This is what Ravenclaw looks like..

Chapter 196 Adventure (Outing)!

"Well, let's begin." Dumbledore gently pressed the faucet, and the carved little snake pattern emitted a dazzling green light when the wand touched it, but it was soon covered by a violet light.

"ssssssssssssssssss..."

Andrew heard a creepy sound coming from a faucet, as if something was about to crawl out of it and attack.

'Snake, yes, it's the snake language?'

With the sound, it began to emit a burst of white light, then quickly spun and grew larger, pressing the pool down, eventually forming a long pipe that people could crawl into.

...

too frightening…

Andrew had roughly analyzed Dumbledore's magic - the professor's undisguised approach made it not that difficult for Andrew to understand.

The spell just cast directly enchanted and activated the entrance, and then gave it a brief magical life. Under the absurdly powerful transformation spell, it opened the blockade of its body using the method it remembered.

In simple terms, it is like a smart door lock that has grown hands and feet, inputs all the passwords it has memorized, and then opens the door...

'Shh... Forget about this lock. Even the Gringotts vault can't defend against this kind of trick, right? But Gringotts seemed to have been stolen last year? That's fine. It's not worthy of it.'

“So interesting…”

Dumbledore stared at the pipe, his admiration obvious, "Without our knowledge, there is a passage leading underground... What a great surprise."

"There is no doubt that someone intervened in the castle's pipeline repair a long time ago, at least hundreds of years ago, and built this secret passage leading directly underground," Professor McGonagall checked the protection of the pipeline, "but no headmaster in history has ever discovered this secret passage."

'It may be found out after checking... No, the headmaster would never hide such a secret room, because he has dozens of ways to expel people that are much better than the basilisk, instead of using a stupid snake to do it.'

"Then the mirror goes down first, and then the water."

Dumbledore clicked his wand and the two transformed creatures shrunk a bit and went into the pipe, "And how are you, Severus?"

Professor Snape said nothing and went into the pipe, followed by Dumbledore himself, then Percy and Andrew. Professor McGonagall stayed last, sealed the bathroom again and was the last to enter.

"It's a pipe network... and even a weak lighting system. Damn, how much power does this castle have?"

Sliding down along the densely packed pipes, Andrew was trying to determine his position all the way.

Maybe the surface...underground...this is almost deeper than the Black Lake, right?
Probably because of the water passing through, the pipe was a little damp, but it was not a big problem. Andrew soon felt a magical force slowing down his descent, and even the slope of the pipe was decreasing.

"thump…"

His butt slid across a section of flat pipe and then gently touched the ground outside the pipe.

A magical force came, he was pulled up, and the dampness on his body disappeared in an instant.

Next, it was Professor McGonagall's turn - but Andrew paid no attention to her at all, concentrating only on the room they were in.

A ball of fire floated from the ceiling, setting the whole place ablaze.

It was part of a tunnel—the walls were clean, the floor was dry, and the bright light of a fire drove away any darkness.

'Damn it, it must have been cleaned by Dumbledore... I don't believe it can be this clean after all these years without anyone using it...'

Andrew was full of resentment - even if he couldn't write directly, he could just use it as material accumulation. How many people have seen a magic secret passage that had not been repaired for more than ten years!
Not to mention that this is the one used to build a school!

But he was a pure idiot who came here only to gain experience, so he had no right to speak. Professor McGonagall looked around for a while and found the exit directly. "Here, another pipe with automatic return effect, also borrowed from the castle's protective magic... Merlin's socks, this one can't really be that, right?"

"Professor, you mean, the Chamber of Secrets?"

Percy hesitated for a moment before blurting out.

"Although we have believed it to be fake for many years, but..." Professor McGonagall looked around, "There is no doubt that this place has existed since the school was founded. I can even only control part of the authority..."

"Let's go, looks like I have to send a letter to a legend - tell them I found another buried treasure."

Dumbledore was joking, but his expression and actions did not show any sign of relaxation—the mirror and the water ball had already gone ahead to explore the way.

"There are a lot of rat skeletons. It looks like there is a creature here that feeds on rats."

Andrew didn't know how Dumbledore communicated with the transformed creatures, but he started reporting from a distance.

As for the problems of light and humidity, they were completely solved by the fire on the ceiling - Andrew could even see traces of magical processing left on the stone slabs.

To be honest, if Andrew didn't know that this was the legendary secret room, he would even feel like he was on a picnic - as if someone was using a one-kill cheat to clear the map.

"Another interesting discovery. Well, wait a moment - don't worry, I'm here."

Dumbledore smiled, and soon, the water ball came over wrapped in a huge snake skin.

"Merlin's socks!"

Percy looked at the snake skin, "Is this a basilisk? Yes, it must be a basilisk. There is a basilisk hiding underground!"

"No doubt, Weasley, and I hope there is more than one basilisk - but I'm afraid there won't be more. Few creatures live for thousands of years."

Dumbledore looked at the snake skin and said, "Perhaps it would be a good gift for Hagrid. Taylor, please accept it."

Collect it?
Andrew was stunned for a moment, realizing that the professor didn't want him to be dragged, but deformed.

He picked up his wand and used all his strength to cast Transfiguration...

"It's harder to transform than I expected. This thing has too high a magic resistance. I just barely have enough mana..."

Fortunately, it was just a dead object - it soon turned into a beautiful cape.

“It’s an improvement over last time…”

Dumbledore nodded, "Go ahead, there is a stone wall ahead, and it seems to have the same lock."

???

This way?

Are you going to kill the snake and give me the skin? Or is it the snake's molt?

Andrew rarely has strong demands for things, but this snake skin is indeed very good for practicing range casting - the magic resistance is higher than that of processed dragon skin. Andrew is sure that the original skin is much better than those common hybrid dragon skins.

But Dumbledore said nothing, he just walked ahead.

The group continued on their adventure (outing), but Andrew suddenly needed equipment.
