The goal was achieved, Chen Yi and Nagini rushed to Hogwarts together, and on the way, Chen Yi asked on a whim: "Sister Nagini, can you become a human with the upper body and a snake with the lower body?"

"Do you mean that?"

Nagini glanced at Chen Yi strangely, and then transformed, her two slender legs quickly turned into a snake body, with the beautiful face of her upper body, the whole person looked like a bewitching taboo.

And because Nagini's lower body turned into a snake body, the whole body was half a head taller than Chen Yi.

"Ah~!! I love it! ”

Chen Yi covered his heart, feeling that he couldn't stand it anymore, Nagini's sister Saigao!

"Chen Yi! Are you okay! ”

Seeing that Chen Yi suddenly covered his heart, he couldn't speak in pain, so he hurriedly twisted his body and crawled to Chen Yi's side, hugged him and asked with concern.

"I'm fine!" Chen Yi broke free from Nagini's embrace and looked around her, and then Nagini saw that the reason why Chen Yi was so excited was entirely because of his appearance at this time.

Seeing Chen Yi blushing a little, Nagini couldn't help touching his snake tail and asked, "Chen Yi, don't you think I'm the way I look now...... Is it ugly? ”

"Ugly? How could it be! Sister Nagini looks the most beautiful I've ever seen! Yes~!!! As he spoke, Chen Yi couldn't help but throw himself into Nagini's arms and hang on to her like a coquettish child.

Seeing that Chen Yi liked the way he was now, Nagini's eyes flashed with joy.

"Since you like it, then I'll keep it like this in front of you in the future." Nagini said softly with a smile on her lips.

"Thank you! Sister Nagini, you are so good!! ”

Seeing Chen Yi happy like a child, Nagini touched his head lovingly.

"Fool, no matter what the requirements are, my sister will meet you, just say it to me directly in the future!"

Chen Yi squinted his eyes and enjoyed the warmth above his head, and after a while, he opened his eyes and said to Nagini seriously: "Sister Nagini, don't always hide alone in the future, from the moment you stand up and block me, I swear that I will not let you be wronged in the future!" ”

Nagini's hand paused, but soon she stroked the top of Chen Yi's head again, only this time the movement was more gentle, and after a while, she was heard to respond softly.

"Well, then my sister will rely on you to protect ......"

......

When Chen Yi returned to Hogwarts again, it was already dark, and Nagini had already inhabited the Black Lake, of course, her arrival would inevitably make a wave of chickens and dogs jump in the Black Lake, and the giant squid was not in the Black Lake at this time, but may have run along the tributaries to other places.

Only some of the fish-people living in the Black Lake were so frightened by Nagini that they hid far away in their nests and did not dare to come out, and it was estimated that they would inevitably go to Dumbledore to complain afterwards......

However, Chen Yi was going to say hello to Dumbledore after a while, so these fishmen were destined to huddle in the corners of the Black Lake in the future......

After returning to Hogwoods Castle, Chen Yi did not return to his dormitory, but walked straight to the library, he wanted to find some alchemy books, and by the way, he went to the forbidden area to see if he could find some interesting magic......

At this time, the dinner in the school had just ended, and a few students walked towards their bedrooms in groups.

Mrs. Pince, the librarian, was also about to close the door of the library at this time, when she heard the footsteps behind her and said, "The library is closed, I want to read the books and come back tomorrow." ”

"Mrs. Pins, I have some important materials to find, just leave the library to me during this time, don't worry, I will close the door when I leave," Chen Yi said with a smile.

Mrs. Pince turned her head in confusion to see which student dared to speak to her like this, only to find that standing behind her was the newly appointed Vice Chancellor, Professor Chen Yi.

"Ah, Professor Chen Yi, I'm sorry I didn't know it was you." Mrs. Pince said apologetically.

"It's okay, can I go in now?" Chen Yi didn't care, but asked her kindly.

"Of course, professors can use the library at any time!"

Mrs. Pins got out of the way, this woman usually regarded the library as her own kingdom of power, of course, this so-called power is only for the little wizards, she doesn't dare to stand in front of the professors at Hogwarts with a squib, not to mention that Chen Yi is still the vice principal!

After entering the library, Chen Yi first searched for knowledge related to alchemy in the general book area, although most of the alchemy books in this area recorded some basic knowledge, but it is always right to lay a good foundation first.

After selecting a few more comprehensive alchemy books, Chen Yi came to the forbidden book area.

The décor here is completely different from the normal area, not to mention the isolation of the books, and most of the books on the shelves are chained so that students cannot sneak them away.

Of course, borrowing a few forbidden books as Chen Yi was just a matter of words, and soon he found the book he needed, a forbidden book containing alchemy and enchantment, and the reason why this book was placed in the forbidden book area was because there was a lot of content about blood sacrifices.

Although it sounds a little bloody, much of the knowledge in it is genuine, and even the master alchemist Nicolame has studied this book.

Putting this book into the system backpack, Chen Yi found another spell book, which not only recorded the three unforgivable spells, but also recorded the fire spell and the Bladeless Spell invented by Snape, although these spells were a little disdainful of Chen Yi, but they could be used to teach students in the future.

Just when Chen Yi was looking at the magic book in the forbidden book area, the door of the forbidden book area suddenly became windless, as if an invisible person pushed the door and walked in, and the strange scene made people feel chills in their hearts.

The corners of Chen Yi's mouth turned up slightly, and with his keen perception, he could easily spot Harry's traces, not to mention the system logo above Harry's head and his mental qi perception, but from Harry's subtle breathing and footsteps, Chen Yi could detect his existence!

Chen Yi looked at the book quietly, pretending not to notice Harry's existence, this legendary boy who was called the savior of the wizarding world was peeking at Chen Yi at this time, as if he wanted to know why this mysterious vice principal would come to the forbidden book area in the middle of the night.

"Does he have any secret to tell?"

Harry thought to himself, thinking that Chen Yi and the troll appeared at Hogwarts on the same day, and he couldn't help but wonder if there really was such a coincidence in the world.

The more he thought about it, the more suspicious Chen Yi became, so he wanted to step forward to see what Chen Yi was looking for in the forbidden book area, but as soon as he moved, Chen Yi took the book and walked outside. Harry, who was still looking for information about Nicolamay in the forbidden book section, had to regret stopping and did not choose to follow.

But what Harry didn't know was that Chen Yi did not leave the library, but also entered a state of invisibility in a place where he couldn't see, and was quietly following him at this time!
