"boom--"

Amid the rolling waves, the dark and damp black rock walls exploded.

The spell hidden on the rock wall instantly shattered in the face of absolute power, revealing a long and dark corridor behind it.

Golden lightning was wrapped around Lin Zhongtian's body, and he slowly flew into the cave behind the rock wall under the shining golden light of thunder.

After passing through a long secret passage, Lin Zhongtian arrived above a black lake. The lake was extremely wide and boundless. The cave that housed the lake was also extremely wide. Looking up, it seemed that there was no top to be seen.

"Is this the traceless extension spell?"

Lin Zhongtian looked around thoughtfully and clearly sensed the magic that shrouded this place.

In addition to the spell of expanding space, this place is also shrouded in some other magic, such as the thick and indissoluble darkness around, which is a kind of magic that blocks vision and gathers darkness.

Well, the effects of these magics are pretty good.

But in front of Lin Zhongtian, it was not good enough...

Lin Zhongtian waved his hand casually, and golden lightning spread out in the shape of branches, like a sharp sword shining with golden light, instantly tearing through the thick and indissoluble darkness around him.

The curtain of darkness was torn apart by the golden lightning, illuminating the entire cave with golden light.

Under the shining golden light, Lin Zhongtian crossed the lake and landed on the black stone slab in the middle of the lake.

Looking at the stone basin in front of him that was emitting a faint green light, Lin Zhongtian stretched out a hand, wanting to reach into the basin that was emitting emerald green light.

At this moment, an invisible resistance appeared out of nowhere, as if the surrounding air had become extremely hard and indestructible, and was trying its best to stop Lin Zhongtian from reaching forward.

But Lin Zhongtian's expression remained unchanged, and his right hand slowly extended forward as usual.

“Crack—”

With a slight crackling sound, the spell contained in the emerald green liquid shattered silently.

The space was torn apart by brute force, and traces of silver light flashed out from the hair-thin cracks around it.

Just like that, Lin Zhongtian ignored the powerful spell and the confined space, and relied on brute force to force his hand into the emerald green body, and took out a golden octagonal pendant box from it.

This thing is one of Voldemort’s Horcruxes, Slytherin’s locket!

And this world is the famous "Harry Potter" world.

I just don't know whether this is the world of movies or the world of novels...

While thinking this, Lin Zhongtian played with the pendant box in his hand with great interest.

According to his understanding of the original book, this thing should be a fake, and the real Slytherin locket has actually been replaced by Sirius's brother, Regulus Black.

At that time, Regulus Black, who decided to turn over a new leaf, drank all the emerald green potions and asked his house-elf Kreacher to take the locket away. As a result, he was dragged into the Black Lake by the Inferi and became one of the Inferi guards.

"Yeah, what about the Inferi in the Black Lake?"

Lin Zhongtian suddenly reacted and looked at the surrounding black lake with surprise.

He felt something was wrong from the beginning, and now he finally knew - why was there not a single corpse at the bottom of the Black Lake?

Lin Zhongtian looked at the black lake surface in surprise. His black eyes could clearly see the empty lake bottom through the dark water.

Where is the Yin corpse?

After a little thought, Lin Zhongtian felt that it was most likely the work of a time traveler from this world.

And based on the fact that the locket is still present in the stone basin, it can be seen that the plot of this world should not have developed to the stage of "Half-Blood Prince".

In this case, the fact that this fellow time traveler who had never met was able to eliminate all the corpses in the Black Lake shows that he is already quite powerful and is very likely to be a senior or even a teacher of the Harry Potter protagonists.

Of course, it is also possible that the other party is gifted and possesses power that is no less than that of veteran wizards at a young age.

But then again, since the other party is a time traveler, he should know that the pendant box here is just a fake, so why would he come here to destroy the corpse?

Lin Zhongtian was a little confused. He threw the pendant box back into the stone basin, splashing emerald green water.

At this moment, the stone basin seemed to sense the return of the locket, and a new spell emerged out of nowhere.

"Can it be recovered?"

Lin Zhongtian looked at the stone basin with interest for a while, then turned around and flew out of the cave.

As we all know, in the world of Harry Potter, time travelers generally only appear in two places——

It was either Hogwarts or Azkaban.

Lin Zhongtian planned to go to Hogwarts first to see if the old fellow villager he had never met was there.

…

…

On the other side, at Hogwarts School of Witchcraft and Wizardry, three second-year kids sneaked into the dilapidated bathroom.

"Do we really have to be here—I mean, should we find a more private place?"

The little boy with red hair and blue eyes huddled at the door of the toilet, looking around nervously.

Beside him, the fluffy-haired little girl glanced at him and said, "Believe me, Ron, this place is hidden enough. In Hogwarts, any student with a normal mind would never come to this bathroom, even the stupid Goyle and Cleopatra..."

Before she could finish her words, a sharp cry came from the bathroom cubicle, interrupting the girl's words.

The three kids, including the girl, covered their ears together and endured the most unbearable high-pitched stage.

After letting go, Ron Weasley looked at the closed toilet cubicle and sighed: "You're right, Hermione, no one will come to this place with Moaning Myrtle here..."

As soon as he finished speaking, there was another sharp high-pitched sound.

The three children had to cover their ears again.

"Stop talking!"

Hermione glared at Ron, who shrank back.

"Take out the book first!"

The black-haired boy next to him whispered.

He has a pair of bright blue eyes, black and messy hair, and a long, lightning-shaped scar on his forehead. He is the protagonist of this world - Harry Potter.

Hearing Harry's words, Hermione nodded and took out the book that was as thick and old as a brick from her bag.

Hermione carefully opened the magic book, and the three of them leaned over to look at the wet pages in front of them.

With the help of the light from the bathroom, the three children flipped through the pages to find the potion they wanted.

While flipping through the book, they finally understood why this book, "Powerful Potion", was rated restricted.

Many of the potions in the pharmacopoeia have terrifying effects and are accompanied by shocking horror illustrations.

When they saw the illustration of a man with his internal organs turned out, the three little ones couldn't help but scream in surprise. They quickly turned the page and forced themselves not to think about the horrific scene they had just seen.

Finally, after flipping through the pages, they found the potion they wanted.

"It's him!"

Hermione said excitedly, pointing to the page.

Ron and Harry also showed happy expressions.

But soon, the expressions on the three people's faces became complicated.

"This is the most complicated potion I've ever seen!"

Hermione frowned tightly, running her fingers over the list of ingredients, muttering: "Lacewings, leeches, slugweed... and powdered bicorn horns, scraps of boomslang skin, and a little bit of the person we want to become."

Listening to Hermione's words that sounded like a spell, the poor student Ron was filled with awe.

"Hermione, are you sure we want to do this ourselves?"

"What else?"

"How about we go find Fana? She has always been top of the grade in Potions, and even the picky Professor Snape can't find fault with her grades!"

"Don't be naive, Ron, what we are doing is against school rules!"

"So what? Fana has such a good relationship with Harry, she will definitely be willing to help us - Oh, I see, you are not considering her as a competitor because someone else took away your first place in the grade, right?"

"……you!"

Hermione glared at Ron, grabbed the brick book in front of her and pretended to hit him.

Ron was startled and quickly hid behind Harry.

Looking at the two noisy friends, Harry sighed helplessly: "Okay, stop it, Hermione is not that kind of person, and I don't think it's a good idea to find Fana. Although she is my friend, she is also very close to Strelling's people..."

"Oh? There is such a thing?" Ron became interested, his eyes widened, and asked curiously, "Is it Malfoy? No, no, no, Malfoy is not qualified. It should be Senior Ander Kerr who is two years older than us, right?"

Harry nodded: "Well, I heard that they are from the same hometown, so they have always had a good relationship."

Ron's face suddenly became clear, and then he gossiped with great interest: "Do you think that the two of them will..."

“Pah—”

The sudden sound startled Ron and Harry.

The two turned around and saw Hermione put the brick-like books together, glaring at them and saying, "Are you going to do it or not? If you don't want to find out whether the heir to the Chamber of Secrets is Malfoy, I will go find Madam Pince and return the book to her!"

“…”

Ron and Harry looked at each other and nodded quickly.

Ron muttered quietly, "To be honest, I never thought that one day you would encourage the two of us to break school rules."

Hermione couldn't help but glare at him again, a faint blush appearing on her cheeks.

Harry said quickly: "That's it! Hermione, what do you think we should do?"

Hermione snorted softly, turned the page again, looked at the list of materials and whispered, "First, the sap grass, it must be picked on the day of the full moon, and the lacewings, which need to be boiled for more than 20 days..."

Just as the three little kids were hiding in the bathroom and plotting loudly, outside the bathroom, a tall, black-haired boy with slightly pale skin leaned against the wall at the corner of the corridor, his ink-black eyes revealing a thoughtful look.

And on the chest of his robe was the Slytherin silver snake emblem.
