Starting from the Legacy of Hogwarts, he transformed into the Dark Lord.

After leaving Ollivanders wand shop, Saco ran without stopping to the deepest part of Diagon Alley, where abandoned and deserted shops were located.

He randomly picked a shop that he could enter without kicking down the door, walked all the way to the back of the shop, and came to a relatively intact dilapidated house. This place used to be a warehouse, with many nearly rotten wooden frames lying around. After setting up a chair for himself, Sako plopped down on it.

The small bag, which had originally contained a lot of money, now looked rather bulging. After spending money to buy his first item in Diagon Alley, he realized what his cheat code to time travel was.

It's Fenglingyueying, and the mods he installed!

He clearly remembered that he had activated the feature where the store would pay him back when he bought something.

So, whatever amount he spent on something, he would get double the money back – one part was the principal, and the other part was extra money from the shopkeeper. At this moment, the Hogwarts scholarship had doubled; without counting, it was always fifty or sixty Galleons.

"Why can't you use credit cards in the magical world?"

Using metal coins is too troublesome, especially bronze knat. One gallon can be exchanged for 493 broken bronze coins, which are numerous and heavy. After taking out all the shiny gold gallons, he threw away the remaining silver shiko and bronze knat. Now that he didn't have a bag with the Unseen Stretch Charm, he was too lazy to carry so much money that he couldn't spend it all.

The money you lose won't increase; only the money you spend will come back to you.

"Now that I've become a disciple of Ancestor Fengling, surely the other functions I've unlocked will also be useful!"

With a wand in one hand, Saco opened "Standard Spells: Beginner" in the other, his first-year textbook, and the first spell taught in it was—

"The fireflies are twinkling."

The moment Saco waved his wand according to the pattern in the spellbook and correctly recited the spell, a magical feeling suddenly welled up from the bottom of his heart.

"I have completely mastered this magic."

Looking at the lit tip of the wand, Sarco spoke with certainty.

"So that's where the unlimited experience is used. As soon as I learn magic, my experience is instantly maxed out, jumping directly from beginner to expert."

But soon, Sarko fell into thought again.

He had a vague feeling that he could take it a step further.

Following this feeling, Sakho began to experiment. After a few minutes, he suddenly straightened his back and exclaimed, "I've got it!"

"I even added 999 talent points, and this stuff can actually be used here?!"

"Fluorescent lights!"

Saco covered his eyes and flicked his wand, and an extremely dazzling ball of white light flew out from the tip of his wand, illuminating the dilapidated house in every detail.

"This is definitely comparable to a flashbang."

Even with his hands covering his eyes, Sako could feel the burst of intense light. If he used that to ambush someone, he would definitely succeed every time.

After trying the Light Charm, he immediately followed up and quickly flipped through the Charms textbook.

Hogwarts doesn't teach a lot of magic. In the seven books from first to seventh year, there are only less than 50 spells recorded. Especially in the textbooks for the higher grades, after you have learned the basic spells, these books will teach you various spell casting techniques and knowledge about spell expansion.

For example, the Light Charm and the Greater Light Charm adjust and expand the effect of the spell by adding specific modifiers. The Light Charm, which originally only lights up the wand, can now produce a ball of light and change its shape and color. This teaches a more refined and advanced approach to spells.

This stuff is completely meaningless to Sako. He mastered a spell and immediately reached maximum experience level. He already knew these things even without learning them; knowledge entered his brain in a strange way.

"That's too little! That's far from enough!"

"Is this all the basic stuff that Hogwarts' Charms class teaches?!"

Sako's eyes, which had been fixed on the book, were slightly bloodshot. After learning all the "standard spells" recorded in the textbook, his desire for magic grew even stronger.

"No wonder the Hogwarts professors run clubs. The mediocre ones just learn the magic in the textbooks and can manage normal life after graduation, while the truly talented ones get special tutoring. All the good stuff is with the professors!"

"Professor Flitwick... hehehehe... don't hold back, Professor."

"I'm sure I'll be an excellent student, I promise!"

After tossing the book aside, Saco returned to Diagon Alley, changed into a brand new robe, and was no longer dressed as a disheveled vagrant. He received a warm welcome from the shopkeepers whenever he went to any store.

The shop owners who had visited before couldn't recognize that this handsome young man, dressed neatly and smiling brightly, was actually the homeless man they had previously refused to even look at.

Sako immediately went to the magic equipment shop and bought the space pack he desperately needed.

He only had enough Galleons to buy the smallest size bag, but after he went out to shop, in less than two hours, his Galleons were almost overflowing the bag, which had a capacity of about one cubic meter.

"Which is your store's best, most expensive, and most spacious seamless stretch wrap? I want them all!"

The owner enthusiastically recommended his signature dish to the customer who had returned shortly after leaving.

With his entire body completely transformed, Sakho now sported a crossbody dragon-skin backpack and a slightly smaller waist pouch. Both were crafted by top leatherworkers using the toughest fire dragon leather, and then handed over to an alchemy master who used pure gold and high-grade magic gems to create an embedded alchemical array. This expanded the space inside the pouch to the size of two football fields, thirty meters high—more than enough to house a private zoo.

"The same portable zoo that Newt Scamander wears – it's a steal!"

In just one afternoon, the slovenly poor boy was transformed into a suave and extravagant young nobleman. The shopkeepers in Diagon Alley were all smiles. Saco bought things like he was stocking up on inventory, as if he wanted to buy the whole store.

After glancing at the hundreds of thousands of Galleons that had now piled up like a mountain, Saco ended his shopping spree in Diagon Alley. He had bought everything he needed to buy, and he had no intention of ruining the magic world's economy. He didn't want to know where the money came from; if anyone asked, it was Wind Spirit Moon Shadow.

Night had fallen, and a new light had been lit in a guest room at the Leaky Cauldron.

Sakho, sitting on his bed eating a smoked meat sandwich, opened the most interesting book he had acquired that afternoon.

Dark Magic: From Beginner to Expert

This is a book highly recommended by the manager of Boginbock, and it's the best introductory text for enthusiasts of dark magic.

none of them!

This book details the hand gestures and spell techniques for the three Unforgivable Curses, and also thoughtfully includes some fun curses suitable for playing pranks on friends with whom you don't get along.

For example, making people's anus develop taste buds, which is safe and fun.
