For a few days, Zhang Xuan's life was very peaceful, and at one dinner time, Dumbledore announced that the basilisk had been killed, and the medicinal materials for rescuing the petrified students had begun to be cultivated, and everyone relaxed.

Only Zhang Xuan Harry already knew about this and didn't care.

"Looks like Dumbledore must have been to the Chamber of Secrets!" Harry whispered, "Otherwise, some of them are proficient in snake language, or they won't know that the basilisk is dead!" ”

Zhang Xuan raised his eyebrows, he didn't expect Harry's mind to turn so fast! It seems that his experience has also made him grow a lot these days!

"Harry guessed right!" Hermione also said, "But it looks like Dumbledore and they are not going to explain more!" It seems that Harry has to prove his innocence and find the secret room! ”

"That's right!" Harry nodded, "I've been thinking for the past few days, the basilisk can only petrify people by seeing their eyes, so how does it manage to run around the school without being noticed?" ”

"Could it be invisible? Like a chameleon? Ron wondered, "Or is it a transparent snake like a jellyfish?" ”

"I don't rule it out!" Hermione said, "But I've made a new discovery these days, the secret room was opened fifty years ago, and then the first victim appeared!" ”

"Who is it?" Harry asked hurriedly.

Zhang Xuan looked at Hermione with a smile, and she said the expected answer, "It's the myrtle in the abandoned bathroom!" ”

"Looks like we're going to have to go find her!" Ron said, "Let's go, let's go now!" ”

As he spoke, he was about to go to the bathroom, but Professor McGonagall came over: "Zhang Xuan, please come with me to the principal's office!" ”

Harry glanced at Zhang Xuan and said, "Let's go by ourselves!" ”

With that, they hurried away, apparently not wanting Professor McGonagall to know of their plans.

"Okay Professor McGonagall!"

Zhang Xuan smiled, and looked at the figure of Harry and Hermione in the distance, this group of little ghosts is really reckless enough, when they encounter danger, they just think about their heroes, if it weren't for the secret protection behind them, they don't know how many times they died!

Follow Professor McGonagall to the third floor, where you will see a large statue of a phoenix.

"Headmaster Dumbledore, Zhang Xuan is here!" Professor McGonagall said to the statue.

Then the phoenix's eyes lit up, and it moved to the side, revealing a staircase.

"Alright, just go up!" Professor McGonagall hurried away.

Zhang Xuan's heart was happy, no wonder Dumbledore could live so long, this caution was very rare.

Just now, the eyes of the scenery statue lit up, and then the gem of Zhang Xuan's belt also lit up, obviously there was some detection magic, and Zhang Xuan searched his body.

And others just thought that this was a reminder that there was a staircase entrance, but they didn't know that they had been screened through.

When I went up the stairs, I saw a small office.

Just like many offices have a large bookshelf in the background, Dumbledore's office is no exception, with portraits of past headmasters hanging on the wall. The phoenix, which has been alopecia, is drowsy on the shelf.

So bald?

Didn't Dumbledore pluck your hair and go to the clutches?

You must know that phoenix feathers are very good magic materials.

After two turns, Dumbledore came down, he had eyes at this time, holding a crystal ball in his hand, looked at Zhang Xuan and smiled:

"Welcome, welcome, I didn't expect Zhang Xuan, you to be such an excellent student!"

"I wonder why the principal said this? I'm just a student who likes knowledge! Zhang Xuan said with a smile.

Dumbledore sat down and said, "Don't stand, don't be inhibited, sit down and talk!" ”

"Thank you!" Zhang Xuan leaned back in his chair, but saw Dumbledore using a crystal ball in his hand.

In the crystal ball, there was an image of Zhang Xuan entering the secret room and summoning Nasario to kill the basilisk.

Fortunately, Zhang Xuan was cautious by nature, so Tom Reardt hid in the diary and did not show up, otherwise Zhang Xuan would have lost an excellent magic instructor.

"I didn't expect you to be not only very smart, you know how to use strong light to block the petrified vision of the basilisk, but also have such magic that you can summon all the spiny dragons, which is really incredible!" After Dumbledore finished showing the video, he smiled and said to Zhang Xuan:

"This is the best student I've ever seen in fifty years, with a wealth of knowledge, great magic, and perfect tactics! Kill the basilisk without much effort. ”

Zhang Xuan looked at Dumbledore with an admiring look on his face, not happy or sad in his heart, knowing that he still had questions.

Sure enough, Dumbledore said again, "I'm curious, do you also know snake language?" How did you get into the Chamber of Secrets? ”

It seems that Dumbledore didn't take pictures of the bathroom, and he probably didn't be embarrassed to shoot it, but it was a women's bathroom, and this magic monitoring crystal ball was not exhaustive.

There is no scene in the bathroom, there is no image of Zhang Xuan in the pipe, and the perspective in the crystal ball is also condescending, Zhang Xuan immediately judged the location of the crystal ball to collect the image.

It's in the upper right corner of the secret room, just like the one you can get an overview of.

I didn't expect to find it in the secret room last time, and it seems that I was negligent.

"The Alajo Cave is a very useful magic to open the door!" Zhang Xuan smiled: "The secret room has been built for too long, so there is no Shakya to resist the magic of the Alaho Cave!" ”

Alaho Cave is also known as a thief's friend, and it is first-class to pick the lock, but it can't be opened for things that are sealed with extremely strong magic, but some simple spell seals can't be stopped.

"I see!" Dumbledore nodded, "So how did you find the basilisk?" ”

Seeing Dumbledore looking at himself, Zhang Xuan smiled calmly: "On the way back that day, I found a flash of gems on my belt, which is a magic detection device I made, and if magic is released towards me around the detection path, it will flash!" ”

Zhang Xuan pointed to his belt and continued: "I turned around and found nothing, given that there were people in the school who were petrified, I realized that this was the petrified gaze of the basilisk!" ”

"Then it's easy! I walked around the school with my sunglasses on, narrowing it down little by little, and finally I was in the bathroom! Zhang Xuan said with a smile.

"Really? Will you show it to me? Dumbledore seemed very interested,

"Absolutely!" Zhang Xuan said with a smile, although it was very unsightly to untie his belt to this old man, Zhang Xuan still handed it over.

Dumbledore took it and looked at it himself, and then with a movement of magic, the jewel of the belt buckle really sensed, and the red light flashed.

"Very good warning magic!" Dumbledore smiled, "There are several precious materials mixed in it, as well as a detailed magic circuit, I didn't expect you to have such a high talent for alchemy!" ”

Dumbledore returned the belt to Zhang Xuan, "But you must also be vigilant not to fall into the dark vortex of alchemy, my good friend Nick Lemamel is an example!" ”

Nick Lemay is said to be over 600 years old, a monster that is gradually decaying, and the Philosopher's Stone makes him immortal, but it cannot stop him from aging and decaying. The Philosopher's Stone slowed down the process of his death considerably, which can be described as torture.
