HP: At the beginning, I influenced Snape's childhood.

Several days have passed since the troll incident and the Quidditch incident, and Snape will soon be acting as the referee for a Quidditch match. Lin Mo knows that Snape dislikes Quidditch and hates such occasions; if it weren't for protecting Harry, Snape might prefer to be with Potions.

Moreover, given Snape's reputation among students, he would certainly be accused of trying to suppress Gryffindor and Harry.

Currently, Lin Mo doesn't have the energy to deal with these matters. He's about to face Voldemort after the troll incident. Although Lin Mo possesses advanced magical talent, he hasn't learned the three Unforgivable Curses, nor has anyone taught him. And facing Voldemort, who's obsessed with Avada Kedavra, Lin Mo has virtually no means of dealing with him.

Recalling his previously created spell abilities, Lin Mo became very interested in this. Currently, all the spells he could access and was allowed to use were white magic with almost no offensive power, excluding weapons, of course.

In terms of attack power, white magic is indeed inferior to black magic. After all, the great white mage is right here, and even if he had powerful white magic, he wouldn't dare to use it, let alone let Lin Mo learn it.

Therefore, creating his own spell is currently the best option. Although Lin Mo's strength is low compared to the current powerhouses, strength doesn't equate to research ability. In fact, Lin Mo's research ability is very strong, and according to what he learned from Chang Feng, this self-created spell only involves three steps.

The first step is to find a desired spell template and break it down. The second step is to incorporate your own ideas using mature techniques, making appropriate modifications. The third step is to practice in real-world scenarios and refine the scheme further.

Of course, the reason why this first step required using someone else's spell to break it down was because Lin Mo's proficiency and skill level were not yet up to par.

After careful consideration, Lin Mo chose two spells: the Armor Charm and Snape's Omnipotent Spell. The Armor Charm was easy to handle, but the Omnipotent Spell required him to find Snape. As for the location for the actual combat, Lin Mo decided on the Forbidden Forest.

Without further ado, Lin Mo went to Snape's cellar during his free time. The stone serpent coiled at the entrance was already used to seeing Lin Mo. After all, apart from those who were often punished by doing hard labor, he was the first student who liked to come here often.

As you can see, even Draco avoided coming if he could avoid Snape's low-pressure intimidation. (ಥ_ಥ)

Snape was sitting at his desk grading papers. Well, this self-proclaimed poor Potions Master was wasting his precious potion-making time grading these monstrous scribbles that gave him a headache and made him extremely angry.

He already knew when Lin Mo arrived at the door, so with Snape's consent, the cellar door was opened by the stone snake.

"Sir!" Lin Mo's voice sounded particularly abrupt in the silent cellar, like a ray of sunlight shining into a dark valley.

"Mr. Lin, please mind your Slytherin manners," Snape said, pausing before continuing without looking up, "Oh, what brings you, the renowned hero who vanquished trolls, to your poor professor's dark and cramped cellar?"

Lin Mo felt a headache coming on. Every time he saw Snape, he would get a few sharp words from this master of rhetoric. Helplessly, he protested in a low voice, "I'm still a Ravenclaw, you know..."

Hearing the child's "mutterings," Snape looked up at Lin Mo. However, since Lin Mo was standing while he was sitting, it was tiring for him to keep his head up. Snape gently raised his hand, and a chair was placed behind Lin Mo.

Seeing this, Lin Mo readily sat down. Well, he regretted it the moment he sat down; the oppressive atmosphere surrounding Snape quickly enveloped him. However, even though Lin Mo knew his words would cause this outcome, he still wanted to see the Serpent's reaction. |ω・）

"Is Mr. Lin dissatisfied with Slytherin and wants to leave for Ravenclaw?" Snape frowned. He had heard that Lin Mo hadn't been sleeping in his Slytherin room every night recently.

"No, no, no," Lin Mo quickly denied, but seeing Snape's unmoved expression, he quickly softened his stance, "I was wrong..."

"What did I do wrong?" Snape pressed on relentlessly about this matter, which wasn't exactly fair. His mood improved considerably, his body relaxed a bit, and he leaned back in his chair.

"I..." Thinking to himself, "How would I know?", Lin Mo gave up. "If you think I'm wrong, then I'm wrong, but could you please stop calling me 'Mr. Lin'?"

Instead of using "您" (nín), they used "你" (nǐ). While "您" is respectful enough, it carries a sense of distance.

"Alright," Snape said, seeing this, and decided not to tease Lin Mo any further. "So, Mo, what do you need me for?"

"I want to learn the Divine Sword Without Shadow."

"What did you say?" Snape wondered if his ears were playing tricks on him lately because he'd heard so much talk about the trolls in the upcoming Quidditch matches. "Say it again."

"Sir, I want to learn the Divine Edge Without Shadow." Lin Mo repeated.

"No." Snape's brow furrowed even more. What was a first-year student doing learning dark magic, and how did he know about the Divine Strike? Snape remembered that he had never used his spells in front of Lin Mo.

"Sir..." Lin Mo didn't know how to talk to Snape, and hesitated for a moment, "I need to have a way to protect myself."

It's not a question, it's a statement.

Upon hearing this, Snape's heart tightened, but his face remained expressionless. Snape had known since the day Lin Mo killed the troll that Dumbledore, that old fox, was using Lin Mo as a backup pawn, one that would soon be placed on the board, and that Snape couldn't stop him.

He had always known Lin Mo was perceptive, but he hadn't expected him to be this perceptive. Snape knew the matter was settled, so he ultimately agreed.

Snape took a yellowed Potions textbook from the drawer on his left and handed it to Lin Mo: "Here, take it. Study it yourself."

Lin Mo nodded, opened the book, and saw notes and research results written in a single hand on the page. Compared to his current handwriting, the handwriting had more of a naivety and high spirits, and less of a composure and depth.

Of course, he flipped to the pages of "The Unseen Swordsman" and "The Half-Blood Prince." Lin Mo's gaze was fixed on that spot, and Snape raised an eyebrow but said nothing.

"Draco, you should thank me. I saved you from being hit by the Divine Strike." Lin Mo thought to himself.

For the sake of academic research, Lin Mo shamelessly occupied a quiet corner of Snape's office, borrowed a quill pen and parchment, and began to write and draw.

Snape opened his mouth as if to utter something sarcastic, but ultimately remained silent. In his heart, this boy, whose appearance and behavior so closely resembled his old friend—the boy he had once hurt—shouldn't be involved in this game. If it weren't for his prophecy to Voldemort, none of this would have happened…

The boy, who was writing with his head down, paused for a moment, but Snape, distracted, did not notice.

Severus, are you taking the blame for everything again?

A——L——W——A——Y——S

With the Quidditch match drawing ever closer, Lin Mo was focused on creating spells, undisturbed by anything except attending classes and doing homework.

He was also surprised by the quiet period, as Dumbledore hadn't invited him for tea.

Unbeknownst to Lin Mo, Snape had later advised Dumbledore to postpone the White Lord's actions. However, just as Snape's persuasion was about to lose its effect, a handsome man imprisoned in Nurmengard suddenly had a stroke of genius and escaped. This left Dumbledore overwhelmed and with no time for Lin Mo. (After all, he spent all his time with his old flame (｢･ω･)｢hey)

However, Snape had recently noticed that he was hearing far fewer rumors about the trolls, and he guessed that perhaps the novelty had worn off. But he didn't care about anything else.

In reality, Lin Mo used his and Draco's influence in Slytherin to silence the snakes, and as Slytherin students, they didn't want to tarnish their headmaster's reputation, so very few people discussed the matter.

Meanwhile, the Ravenclaws doted on this smart, capable, and handsome freshman who constantly boosted the House's points. Although the hawks weren't particularly concerned about grades, who wouldn't like to have higher scores? So when Lin Mo brought it up, all the hawks unanimously stopped discussing it, and besides, they weren't exactly gossipy.

Harry promised Lin Mo and Draco that he would ensure the Gryffindors would minimize their attacks on Snape until the truth was revealed, so the Gryffindors quieted down considerably under the guidance of the Golden Boy.

As for the most gossipy little badgers, they only dared to discuss it behind the backs of the giant bats they saw. Therefore, the amount of discussion about Snape refereeing Quidditch matches at Hogwarts was significantly less than in the original stories.

Since Lin Mo enrolled, Snape had always liked to have him handle potion-making materials. This was because Lin Mo was quite capable and willingly provided Snape with free labor, so the two had an unwritten agreement of unilateral labor. Lin Mo would have two free days each week to come to the cellar to help process the potion materials.

Although he was supposed to be helping, Lin Mo was very efficient and rarely needed Snape to handle things, so he naturally became more and more adept at using him.

However, Lin Mo had been busy researching spells lately and neglected this matter, so Snape had to do it himself again. As the old saying goes, it's easy to go from frugality to extravagance, but difficult to go from extravagance to frugality. Accustomed to Lin Mo's efficient and hassle-free approach, Snape looked down on the herbs that other students had processed, and doing it himself would be a waste of time.

Congratulations to Lin Mo on receiving a long-term cellar work card.

After Lin Mo discovered this, he quickly took over the task. Large chunks of time in the evenings were spent researching spells, so he could only travel back and forth between the classroom and the cellar during breaks between classes. The time became shorter and the work schedule became longer. What could have been done in two nights a week now required him to run to the cellar almost constantly.

Snape was already used to the fact that he would find more processed herbs every time he returned to the cellar after class, and that he would often run into Lin Mo coming and going in a hurry.

The potions professor had no intention of helping, because Lin Mo often used this opportunity to ask him questions and frequently came to the cellar at night to conduct experiments. Therefore, both of them used this matter as a medium and a reward.

The Quidditch match finally arrived, but Lin Mo didn't go out to watch. During this rare free time, he continued to refine the spell he had already completed in the cellar. Before Snape returned, seemingly somewhat angry, Lin Mo finished the final touches; he planned to go to the Forbidden Forest that very night.

Back in the cellar, Snape's anger vanished instantly, replaced by his usual calm. Seeing Lin Mo packing his things, Snape asked, "Is the research finished?"

"Yes," Lin Mo replied with a smile, looking at Snape, "I've troubled you these past few days, sir."

Snape nodded and sat down on the sofa to read. Lin Mo packed his things, nodded slightly, and left without saying a word.

—Night, Forbidden Forest—

Although most of the animals here no longer harm humans, a small number are still the bad apples, and Lin Mo chose to target these animals.

Lin Mo then defeated the animals with an overwhelming force. A passing centaur, using the moonlight, looked at the animals lying on the ground, glanced at Lin Mo, and then turned and left without saying anything.

Lin Mo cleaned up the battlefield, collected some useful medicinal herbs, and left. He named this self-created spell "Heavy Sword Without Edge."

It is an offensive spell that can rival the Divine Sword Without Shadow, and even has greater potential for development than the Divine Sword Without Shadow, but it is not entirely an offensive spell.

It possesses the defensive and reflective capabilities of the Ironclad Curse, even ensuring that the victim is only severely injured when facing the Death Curse. Of course, this was something Changfeng told Lin Mo; Lin Mo wouldn't give himself a chance to face the Death Curse just to test his abilities.

Logically speaking, the Death Curse should not be blocked by magic, but due to the series of buffs that Changfeng gave Lin Mo for free, this curse has this incredible effect.

As it turns out, Lin Mo is the group's favorite.

--border--

A man in camouflage was escorted out by a group of people. Although he was already over 1.8 meters tall, he was only 15 years old.

A voice echoed in Lin Boyan's mind: "No way... Breaking Waves?"

"What?" Lin Boyan didn't react for a moment. "I remember you seem to have a second older brother... are you talking about him?"

"Hmm, Boyan, the contractor of this guy in front of you is my second brother." Zhi Gua's voice was serious. He thought to himself: Oh no, he brought a practitioner with him too! Oh no, my eldest brother's favor has been divided in half again. (ಥ_ಥ)

The man being held captive looked up at Lin Boyan and suddenly exclaimed in surprise, "Yanlong!?"

After talking to Zhi Gua, Lin Boyan felt relieved. Zhi Gua and Po Lang also contacted each other. After confirming that their practitioners would not be in danger, the two of them started arguing because of Chang Feng.

"You know me? Who are you? What's your name?" Lin Boyan waved his hand, then released his grip, and the person straightened up and stretched.

"Of course I've heard of the God of War. I am Tang Chen, Commander of the Shadow Court." The man introduced himself.

The surrounding subordinates did not show any other expression. They were all loyal to Lin Boyan and naturally would not pay attention to such things.

"Yingting..." Lin Boyan murmured softly, then, as if remembering something, "Do you know my younger brother? His name is Lin Mo."

"Xiao Mo?!" Tang Chen, who had been expressionless, finally reacted strongly upon hearing this name. "We were both spies in the Dark Night, but how could he have an older brother?"

"This is a long story, and it's not safe to stay in the border region for long. Let's go back first. Xiao Mo is still studying at Hogwarts; this is the Harry Potter world." Lin Boyan explained briefly, then gestured for his subordinates to form a protective formation around the two of them.

Lin Boyan pulled Tang Chen and his men away.

Author's ramblings: Hahahahahahahahahaha, the time-traveling formation has finally reunited. Don't worry, Lin Boyan and Tang Chen don't have many scenes.

Well, Po Lang and Zhi Gua are brother-complex characters, Tang Chen and Lin Boyan are brother-complex characters, so... guess who Lin Boyan's partner is? |ω・）
