[Abyss Invasion: Enemies will be strengthened and become even more ferocious]

[Identity: Wizard]

You are a Hogwarts graduate. Your only redeeming quality might be your quiet, unassuming nature. Nostalgia for your time at Hogwarts has led you to write an application to return and become a Defense Against the Dark Arts professor. You are now awaiting a reply.

When Tan Wenjie's vision flashed again, he had already arrived in the world of Harry Potter.

There are only a few thousand wizards in the entire magical world, and even the renowned Hogwarts only admits a few dozen students each year.

It's no exaggeration to say that Voldemort's fight was just a village-level battle.

Tan Wenjie looked down and checked his belongings. Apart from this somewhat dirty and messy fur coat, he only had a magic wand.

You have obtained the "Unicorn Wand"

You have acquired the talent "Wizard Bloodline"

Wizard Bloodline Lv1: Possesses considerable talent in magic, maximum mana +10
You have acquired the skill "General Wizard Magic Lv1"

Wizard General Magic lv1 (0/30): Has not specifically studied any magic, but has already mastered some general magic.
【Chestnut Unicorn Core Wand (Magic Weapon - Right Hand): Chestnut wood wands possess exceptional talent in taming magical creatures, herbalism, and flight. The unicorn core reflects your inclination towards justice in all areas.】

I got up and went outside; it was a dense forest.

Tan Wenjie's dilapidated wooden house looked all alone.

"Shhhhh."

There was a slight trembling sound in the woods, as if something was rapidly approaching.

He glanced at "General Wizarding Magic" and chose to upgrade the skill to the maximum level.

You have fully mastered "General Wizarding Magic". This reduces spellcasting cost by 10% and increases your maximum mana by 30.

Tan Wenjie casually grabbed the water demon beast talisman embedded in the dragon cloth shoe and placed it on his magic wand.

A gentle wave.

"Clear water like a spring"

"Boom!" X8
Eight enormous water snake heads crashed through the ground, shooting straight into the sky and overturning rows of trees.

Amidst the flying, broken trees, several twisted figures were thrown into the air, tumbling in terror.

A massive eight-headed water snake coiled around Tan Wenjie, surveying all directions and perfectly protecting him.

"So this is magic." Tan Wenjie looked down at the magic wand in his hand, completely indifferent to the torn figures.

They appear to be some kind of dark magic creatures.

He put down the wand, and the eight water snake heads vanished instantly.

The difference in their strength was too great; they weren't even qualified to be tested on him.

Trees, rocks, dark creatures, werewolves, etc., are all just dust. With a flick of your sleeve, you can sweep away any number of dust particles without a second thought.

"Let's just find Voldemort and kill him."

He could choose to speedrun, and besides, there's nothing worth staying here for; perhaps those magical gadgets might be of some interest.

"And alchemy."

The system's alchemy is still worth studying.

"And the Deathly Hallows."

Since the Deathly Hallows are the exclusive artifacts of the Grim Reaper, then perhaps those things would also be suitable for the Eastern "Grim Reaper" Fengdu Emperor.

Some weapons and items are like that; their individual functions may seem ordinary, but when combined, they can achieve excellent results.

As for magical creatures, they're not nearly as impressive as real mythical beasts. If they were demons or angels, Tan Wenjie might actually catch a couple to keep as babies.

Even if you don't use it, it looks nice to have around.

Several faint lights suddenly flew towards him.

It is the scattered soul power of the destroyed object.

But there was something else that caught his attention.

[Soul Essence *1]

"Hmm?" Tan Wenjie frowned.

He took out the essence of the soul and examined its identity information.

Tom Riddle

It seems the news that he was about to become a Defense Against the Dark Arts professor had reached the ears of the infamous Voldemort, who was now planning to find a place to reside on the back of his head.

I sometimes like to scratch the back of my head, and I don't really like having something sucking its fingers on my back.

Voldemort never expected that an ordinary adult wizard could kill him in one move.

Tan Wenjie opened his palm, letting his soul power and soul essence fly behind him. A huge but bare lotus tree phantom appeared out of thin air, and as soon as the soul essence entered it, a cluster of lotus trees was lit up.

A ghostly soldier belonging exclusively to Tan Wenjie is being conceived.

"Seven Voldemort Horcruxes are equivalent to seven essences."

The desire to become partners in justice is growing stronger.

“Key plot characters will drop their soul essence.” Tan Wenjie quickly came to this conclusion.

So Harry Potter, Dumbledore, and Snape should all be able to drop.

But the thought of being an honest and good person made him suppress it.

If it's true, there are too many options available; there's no need to persecute good people.

Tan Wenjie went to the fireplace, found the Floo Powder in the house, and read out his destination.

"Flip-over Alley!"

He needs to get rich, he needs to make quick money, so that he can more easily and quickly realize his vision.

Bang.

Tan Wenjie's figure disappeared into the dilapidated house, and after he left, the house suddenly exploded.

An owl flew in carrying a letter, looked at the devastation and dilapidated wooden house, and then turned away in confusion.

……

Moving around in the fireplace felt uncomfortable, especially since he was currently very "weak".

With a gentle touch of his finger, the "bone necklace" hanging around his neck instantly came to life, transforming into a skeletal arm. The skeletal fingers spread out and pressed against Tan Wenjie's face, peeking out through the gaps between them, forming a skeletal mask that appeared to grow from his collarbone and cover his face.

His attire fits the atmosphere perfectly, and no one would be foolish enough to cause him trouble.

But trouble always finds its way in... I'm talking about Tan Wenjie, who is now that trouble.

After selecting his men, he randomly picked an unlucky guy based on his own mood.

"boom!"

The shop door was kicked open.

What store? Never mind, it's not important.

As he entered, he said in a muffled voice, "You actually dared to send someone to assassinate me."

"Huh?" The dark wizard in the shop looked bewildered. "I'm not, I didn't. Who are you?"

Other passersby were already used to it; the bolder ones stopped to watch, while the less daring ones kept their distance.

Something similar happens every now and then in Knockturn Alley. The anger lasts until the Aurors arrive, and then they immediately become lawful wizarding citizens when the Aurors shout "Expelliarmus!"

"Avada Kedavra... never mind." He strode forward and knocked him to the ground with a single punch. "Robbery!"

Tan Wenjie briefly searched the dark wizard's cabinet and found only a dozen or so Galleons.

Being a robber is such a dead-end job.

The dark wizard, huddled in the corner of the shop, looked at Tan Wenjie, worried about getting punched again, and immediately said, "This is all my possessions."

"Are there any restrictions on exchanging British pounds for Galleons in Gringotts?" Tan Wenjie asked.

“Restrictions? No.” The dark wizard shook his head. “However, Muggle currency is difficult to obtain.”

To ordinary people, wizards are characters who only exist in legends and stories. And to wizards, ordinary people are the same. The complex social rules that they cannot understand will make many wizards hesitate to take the path.

Human society is developing rapidly, but the wizarding world has been reciting the same spells for hundreds of years. Some minor innovative papers are nothing more than exam subjects to get an O in the OWLs exam.

With insufficient population and abundant resources so that survival is no longer a concern, stagnation in development seems inevitable.

Tan Wenjie has a completely new idea.

Even the poor wizards, even those from pure-blood families, are merely the richest among 3000 wizards.

But looking at the entire planet, any few wealthy individuals out of billions of people would have enough wealth to overwhelm the British magical community.

This is the difference between the richest person in the village and the richest person in the world.

Wizards can't use magic to plunder in the Muggle world, and Tan Wenjie doesn't need to use magic either. Seizing the opportunity of 1991, he has too many ways to make money. If he adds a little bit of "technique," his money-making speed will be greatly increased.

Not only Gringotts, but also the wizarding world in Europe and America can exchange for Galleons.

After leaving Knockout Alley, Tan Wenjie quickly took a few steps, removed his disguise, entered Diagon Alley, and left through the Leaky Cauldron.

Hogwarts, Headmaster's Office.

Dumbledore was looking forward to Harry Potter's enrollment, but one thing made him frown.

His chosen new Defense Against the Dark Arts professor, Tan Wenjie, has gone missing.

This student was nothing special; his grades were average, and he had a very weak presence during his years at the school. However, with the Defense Against the Dark Arts class cursed, someone had to be willing to take on the role.

A former student who makes no mistakes is a very qualified candidate.

"Albus, don't worry, maybe that kid is already dead." One of the portraits of past principals hanging on the wall of the principal's office offered words of comfort.

His expression, however, was one of schadenfreude.

“I believe the situation won’t be that bad, but we need to find a new professor now.”

Dumbledore had to prepare for the worst.

……

Time flies by.

It's no secret that Harry Potter, the savior who once defeated Voldemort, will be attending Hogwarts.

Harry Potter did indeed follow Rubeus Hagrid to Diagon Alley after a series of fantastical adventures.

The Leaky Cauldron, located on Charing Cross Road in Westminster, London, is nestled between record stores and bookstores. Knocking on the brick wall in the backyard of the pub will officially lead you into a magical world.

The premise is that the correct method is used.

First do this, then do that...

"Harry Potter! Can I see that?"

This was the sentence Harry heard most often today. Whenever someone mentioned it, he had to lift the bangs covering his forehead to show them the scar.

He gradually went from nervous to expectant; the feeling of being admired was wonderful.

It felt as if I were standing at the center of the world, even though there were only two or three thousand wizards in the entire British wizarding community, which was a huge gap from the center of the world.

Moreover, his parents left him a large sum of money, which was a pleasant surprise.

"This is the Lady Malkin's Robe Shop..." Hagrid introduced enthusiastically.

Harry, standing nearby, couldn't help but remind him, "Hagrid, but it says 'Robe Specialty Store - Tan Wenjie Chain Store' on it."

"Oh, that's... wait, what did you say?" Hagrid rubbed his eyes to make sure the sign was correct.

Just then, Mrs. Malkin came out of the shop.

"Hagrid, it's been a long time."

“Mrs. Malkin,” Hagrid wasn’t one to hide his feelings, “Why did you change the name of your shop?”

“They acquired it with a lot of money and even gave me shares.” Mrs. Malkin said with a smile. “I love this job, you know Hagrid. He made me earn more and was able to continue doing all this, still in full charge of everything.”

In short, he gave far too much.

"Congratulations!" Hagrid sincerely congratulated Mrs. Malkin.

"We have an event, come on little wizard, there's a discount on new wizard robes!" Madam Malkin smiled at Harry.

Harry followed Madam Malkin into the shop with a stiff expression. After taking their measurements, they were going to buy an owl, a wand, and books.

“Let’s go, Harry. We should go to Flourish and Blotts to buy some books.” Hagrid pulled out a book list that was ridiculously small compared to his palm.

At this moment, Mrs. Malkin suddenly said, "If you want to buy books, I recommend Tan Wenjie Bookstore." "Has Flourish and Blotts been acquired as well?"

“Of course not.” Mrs. Malkin shook her head. “But Jay’s bookstore is cheaper. Not only does it offer discount coupons for first-time wizards, but if you get a membership card for the first time, you can use the points earned from this purchase on a 1:1 basis for your next book purchase. He even invited Gilderoy Harlot to hold a book signing.”

When the internationally renowned author, who had won the "Most Charming Smile Award" and the "Sir Merlin Order, Third Class" award, was mentioned, a happy smile appeared on Mrs. Malkin's face.

She got the autograph right away; it's an employee perk.

Hagrid took Harry outside in confusion, and sure enough, they saw a much larger new bookstore that had opened right across from Flourish and Blotts, with the straightforward name "Tan Wenjie Bookstore".

A long queue had already formed at the entrance, and it was full of housewives.

The Flourish and Blotts bookstore across the street was deserted, with only the owner grumbling and cursing.

Just then, a family with striking red hair walked by, and the plump woman at the head of the group was comforting her child: "That's Gilderoy Harold's autograph session, Ron."

The little redhead looked a bit aggrieved: "But I still need a new wand."

"Don't worry, Mom has enough points on her membership card to help you get a decent magic wand."

"Really?"

Listening to the family's conversation, Harry couldn't help but take a few more glances.

As Hagrid entered the bookstore, he had just taken out his book list when someone brought him a pre-packaged set of books.

"Brand new, and all at 3% off."

"How much?" Even Hagrid, who wasn't particularly interested in money, couldn't help but raise his voice. "Why is it so cheap?"

"Because this is a Tan Wenjie chain store?" The bookstore employee blinked, puffed out his chest, and looked very proud.

Hagrid couldn't help but say, "I'm starting to get interested in this mysterious guy."

“Hagrid, I thought you would remember me.” A voice came.

Tan Wenjie, dressed in an elegant suit and carrying a walking stick, approached Harry Potter and simply nodded slightly.

"You are... I think I know you."

“We’ve known each other for seven years, Hagrid,” Tan Wenjie said calmly.

This memory may have been inserted out of thin air, or it may be that he really did have a parallel world identity in the vast infinite world, just happened to graduate from Hogwarts, and he came here to take his place.

As long as there are enough parallel universes, anything is possible.

“You are…” Hagrid scratched his head.

Having a big head doesn't mean he has a large brain capacity; now he's just completely confused.

“An outstanding graduate?” He turned to Harry Potter and said, “Tan Wenjie, we will be alumni in the future, Mr. Potter.”

Harry was slightly surprised. This was the first time someone had known his identity and hadn't rushed to look at the scar on his forehead, nor had anyone made a fuss about it.

The other person's composure filled Harry with awe.

The people he encountered along the way were all too flamboyant, but the man before him seemed like a composed adult.

"Won't you lose money selling like this?" Hagrid couldn't help but ask.

Of course, you'll lose money; every single deal is a drain on your wallet.

The business world is like a battlefield. Now he's throwing money at seizing market share, which could force tough businesses like Flourish and Blotts and Ollivanders to go out of business and eventually bankrupt them.

When he controls the entire market, everything here is his.

Whether it goes up or down is entirely up to you.

Moreover, it's just a small market of 3000 people, which is nothing compared to his daily income of 3,000. His economy in the Muggle world can easily support 3,000 wizards.

During this period, Tan Wenjie transformed himself from a penniless man into a multi-millionaire through stock trading alone, especially in fields such as computers, high technology, and medicine.

On the Ministry of Magic's side, he is actively investing in and supporting Cornelius Fudge, who has been seeking partners since Millison Bagno's resignation last year.

Dumbledore's willingness to support him was part of the reason, but as a minister, Fudge didn't want to always be at the mercy of others. In the beginning, he would consult Dumbledore on everything, and the White Lord was his reliance.

But as Fudge's time in a high position lengthened, his confidence grew, and so did his ambition.

He is currently working with Dumbledore while actively seeking new partners. The original pure-blood families are good candidates, but everything changes after Tan Wenjie appears.

Facing Hagrid's probing gaze, Tan Wenjie said, "When I was in school, I had many classmates. Some of them couldn't afford wands, some wore tattered clothes, and some had books that their older siblings had left over. So after I earned enough money, I decided to help all the little wizards, no, not just little wizards, but also great wizards. I will provide jobs for more wizards."

“You are such a kind person,” Hagrid said sincerely.

Harry also looked at him with admiration.

Tan Wenjie smiled: "It's all for a better tomorrow for the magical world. I'm sorry, I have work to discuss. I also have an appointment with the Minister of Magic later. Goodbye Hagrid, goodbye Mr. Potter."

“Goodbye, sir,” Harry said immediately.

As Tan Wenjie led everyone away, Harry couldn't help but say, "He's such a fine gentleman."

“Yeah,” Hagrid said, scratching his head in bewilderment. “He was practically invisible in school, but I never expected him to change so much after graduation.”

Hagrid's memory is hazy; he's only certain that there really was such a student who had no presence.

Tan Wenjie left quickly, and many people smiled and greeted him on the way.

This scene is very familiar.

In a very short time, he could point to the shops in Diagon Alley and say that only a few of them were not his.

Even if he bought the whole of Diagon Alley, it wouldn't cost much. So, whether it was a snack shop or a beverage shop, he would take over any store. Meanwhile, the shop owners thought that buying their shops at high prices would only mean buying a storefront, and they could open a new store.

Give a lesson to a young wizard who wants to get rich.

In business, reputation is everything.

They could never have imagined that Tan Wenjie was not only unafraid of losing money, but was even actively contributing his own. If he wasn't afraid of scaring the wizards, he might have given them the money directly.

In business, quality and price are always the most important factors, especially when product quality is the same or even better. In such cases, word-of-mouth can spread rapidly and firmly control the public's psychology.

What truly interests Tan Wenjie in the magical world are potions, such as the Felix Felicis potion, which can temporarily boost luck. Throughout his journey, he has only received a tiny, fixed increase in luck when he becomes an immortal or a god.

But potion shops need wizards, and it's difficult to acquire them by simply throwing money at them. People with skills are generally arrogant and never short of money.

Today, Tan Wenjie is going to discuss a fairly large business deal.

He wanted to buy the Daily Prophet and have dinner with Minister Fudge.

Gringotts was also his target, but the goblins who controlled the wealth were not easy to deal with and were extremely cunning.

If he wanted to bring down Gringotts, it would be very simple: he could deposit a large amount of money, then arrange for wizards to take out large loans from Gringotts, and then withdraw the money in large amounts.

The wealth accumulated by thousands of people over hundreds of years is like a drop in the ocean compared to the wealth circulating among billions of people in a single minute.

But there's no need to do that. If you want a permanent solution, force would be simpler.

Tam Man Kit never forgot that he was a righteous character.

He won't waste too much time in this world, at most one academic year.

……

Before they knew it, the new school year at Hogwarts had been underway for a while. Harry had met Ron and Hermione, and even made a bit of a splash, but none of that mattered to Tan Wenjie. He had no interest in the trio.

He also came to Hogwarts.

He is now standing in the headmaster's office at Hogwarts.

If you were to summon the Water Beast directly here, it would definitely wipe out the entire Hogwarts.

We're not on the same level.

“It’s a pleasure to meet you, Dumbledore.” Tan Wenjie smiled and nodded, then pulled out a chair and sat down.

"Would you like some sugar?" Dumbledore asked.

The fact that the once quiet and unassuming student had suddenly become so cheerful and outgoing made him raise an eyebrow.

This is a good sign.

"Thank you." Tan Wenjie did not refuse.

"You are now a very successful businessman," Dumbledore remarked.

It had only been a short time since we last met, but the other person seemed like a completely different person.

Success truly does change a person from the inside out, and Dumbledore was quite certain that the other person's magic was ordinary.

“I funded the Ministry of Magic.” Tan Wenjie nodded without any concealment. “They allowed me to open a convenience store at Hogwarts, and I now provide jobs for more than 300 adult wizards, helping them support their families. They even have six types of insurance and one housing fund, as well as various holidays.”

"Don't say any more, or I'll be tempted to quit my job as headmaster and work for you," Dumbledore joked.

Tan Wenjie jokingly replied, "That probably won't work. After you turn 50, our company will take care of your retirement. Simply put, you just need to collect money and don't have to work."

The trend of retirement planning hasn't reached the magical world; there are too few people, resulting in a severe lack of both consumption and creativity.

Even though Tan Wenjie has been spending as much money as possible to cultivate the wizards' spending habits, the purchasing power of several thousand people is still disappointing.

He's planning to hold more Quidditch matches.

“I’m already an old man in your eyes, Jay,” Dumbledore chuckled, winking. “Perhaps I really should find a suitable successor.”

Tan Wenjie suddenly recalled his conversation with Minister Fouché during their dinner.

“You could easily become the headmaster of Hogwarts, and even decide who will be the next Minister of Magic,” Fudge said, slightly tipsy, his words a little slurred. “Because you have hundreds of wizard workers under your command.”

In the British wizarding world, with a total population of only three thousand, he has hundreds of employees, who in turn have families, which means that Tan Wenjie has already leveraged nearly a thousand wizards.

The true uncrowned king.

Tan Wenjie nodded: "If you are really willing to step down and make way for someone more capable, I might be able to take over and reluctantly serve as the headmaster of Hogwarts."

"If you were really made the headmaster, what would you do?" Dumbledore asked.

A game scene instantly popped into Tan Wenjie's mind, something like "Training Hermione"?
It's a real shame that a school principal doesn't operate this way.

“Safety,” Tan Wenjie said. “Then, based on each person’s individual characteristics, we will selectively train their skills to make it easier for them to find jobs after graduation.”

Dumbledore expressed his opinion: "I think they can live without worry."

“This may be the happiest time of their lives.” Tan Wenjie nodded in agreement.

Many people find after graduation that the hardships of studying are nothing compared to the hardships of life.

Of course, they can't be replaced like that. Even if they went back to their student days, they would find that they still couldn't endure the hardship of studying.

People tend to idealize the paths they haven't taken, but in reality, they'll regret whatever they choose.

"I wish you a pleasant stay at Hogwarts," Dumbledore said, seeing his guest off.

“Don’t be in such a hurry, Dumbledore,” Tan Wenjie said. “Just recently, when I left England, I was attacked by a group of dark creatures, one of which was quite special.”

Dumbledore had always thought he would keep this a secret, but now that he heard him bring it up, he immediately perked up his ears with interest.

"special?"

"Voldemort."

The air in the principal's office suddenly became cold and silent.

"you sure?"

“I saw him, and I’m pretty sure I killed him.” Tan Wenjie nodded. “He was very weak, vulnerable, and his soul was on the verge of collapse.”

One-seventh of a soul fragment can yield a soul essence; perhaps a complete Voldemort soul can produce a high-quality soul essence.

Dumbledore didn't speak, but simply looked quietly at the completely different student in front of him.

He suddenly realized that he really didn't know the other person at all. Everything about him over the past seven years had been vague, and he had always been just a background character. But now, he suddenly became dazzling.

If the other party really wants to hide, they might be a more dangerous character than Voldemort.

But at the last moment, he said earnestly, "I need your help, Jay."

Between doubt and belief, Dumbledore chose to believe his student.

“Of course, what do you want me to do?” Tan Wenjie asked.

Dumbledore said seriously, "I need to know how much you've researched about Tom, and also, I hope you can come and teach at Hogwarts."

"I thought you would make me the principal."

"I'm about to retire, and I'll definitely recommend you to the Ministry of Magic afterward."

"It's a deal," Tan Wenjie joked.

He eventually landed a job as a professor of Muggle Studies, a very easy job because it was an elective.

No one understands Muggles better than him.

The specific job duties include Muggle daily life, as well as fields such as mathematics, physics, biology, and history. As for the difficulty... calculating the circumference of a circle, the sum of the interior angles of a triangle, etc., are the test points for the ultimate wizard exam.

To make it even more difficult, the examiners themselves wouldn't understand.

Tan Wenjie was also reminded as he left the office.

You have successfully entered Hogwarts, and "Good Performance in Quest 1" has been activated.

[Help Hogwarts students improve their studies and grades; Quest 2 is pending activation]

"It seems I really need to give the little witch a good talking-to." (End of Chapter)
