This is what Ravenclaw looks like..

Chapter 187 Entrance
"It's not about driving him away, but about catching a pervert..."

Percy communicated with difficulty, while Andrew simply took out canned beans from his bag and began to cast a spell.

"Please go out for a while, at least take some protection, it hurts..."

While taking out his wand, he whispered to the crowd around him - act out the whole thing, and don't let people see that you can catch a pervert. Who will believe that you are here to catch a pervert?
Soon, several armor spells were propped up, and the students who had not mastered them hid behind them, with curious looks on their faces like college students who had not been polluted by knowledge.

"Miss Myrtle over there, could you please hide for a moment? Yes, that's what I said, please hide for a moment... And you, don't hide behind the armor spell, or you will get hurt accidentally."

"Huh? You're looking at other girls while you're talking to me? Oh, yes, Myrtle is dead, so there's no need to consider her feelings! I'm not leaving. It's just a spell, and I'm just going through it at most... I'm not afraid."

For some reason, Myrtle, who had stopped crying, looked like she was in a bad mood, and those who followed her followed her example and refused to leave.

"Really..." Andrew complained in a low voice, then raised his voice again and asked, "Are you really not going to leave? It hurts!"

But the crowd of onlookers showed no sign of dispersing.

"Percy, please, can you clear this place?"

Percy tried, but failed - because everyone had a suitable excuse.

"Cast the spell, Andrew."

Percy yelled in frustration.

Andrew sighed - he had warned him, and even if his reputation was damaged, Percy would bear it with him.

Anyway, it just hurts a little, it's not a dangerous spell... at most it will rebound a few times and cause a little damage...

"For the last time, protect your head. This is no joke. Percy, help Myrtle cast an Shield Charm!"

After making sure that no one would be injured and sent to the school hospital, Andrew began to cast the spell.

He swung his wand violently, and the jar began to squeeze wildly, as if someone was trying to crush it. As the wand was raised, the jar began to explode violently, and countless beans flew out, leaving a trail of blue - the place that was hit quickly changed color, but there was no sign of smudge.

This is not a range-effect Transfiguration spell, but a super-simple version that Andrew envisioned for detecting the existence of the Disillusionment Spell - it can now be cast independently.

Following a series of tinkling sounds and mixed screams, Andrew shook his head - as expected, the pervert he had made up did not exist.

The beans that bounced a second time left blue spots that quickly faded away almost everywhere. With such a density, not only people but even mice could not hide.

"Hiss... Andrew, you guy... it seems that you don't have it?"

Percy, wearing an armor charm, looked around the bathroom like Andrew - the noisy crowd was secondary; the key was to catch the pervert.

"And the damn cubicle, and me!"

Myrtle managed to stop crying, and she became furious - Percy's Shield Charm was completely ineffective and had no protective effect on her.

“I don’t know how many beans hit me, passed through my body, and then passed through in the opposite direction!
Do you think that since Myrtle is dead, we don’t need to consider her feelings?”

"Thanks for the reminder, Myrtle, you are such an observant witch!"

Andrew ignored the complaints and responded loudly to Myrtle's reminder - apart from affirming the effect, he really didn't know what to say now.

"I won't forgive you, you bastard, even if you say so!"

Myrtle yelled, then jumped into the toilet and disappeared.

"I cast a spell, but it had no effect."

Percy explained in a low voice, "It may be a problem with the Defense Against the Dark Arts... Most spells are ineffective against ghosts..."

Obviously, even a class leader would not be so crazy as to ask the ghosts in the school to cooperate with him to complete some spellcasting experiment.

The other students were calm, and instead of being scolded as Andrew had imagined, they chattered and started discussing imitation... 'What the hell? What's going on?'

Andrew began to feel worried - could bean bombs become a trend in the school?
But there was no time to think about that now.

After opening the cubicle and checking it once with beans, it was almost certain that there was no pervert in the bathroom.

"Those two bastards..."

Percy gritted his teeth.

"No, it seems that there is..." Andrew shook his head at Percy and raised his voice, "Can we go out? This test is too dangerous. I'm afraid of hurting people."

Now it's easy and the bathroom becomes clean soon.

'preparation…'

Andrew waved his wand, and the floor began to turn into soil rapidly with his feet as the center. The beans scattered on the ground also began to sprout rapidly and grew long roots.

"call…"

When Dou Miao did not appear, Andrew put away his wand and shook his whole body, but his eyes became sharp.

found it…

Although I had made several guesses during the holidays, I was still delighted to find it so smoothly.

He only noticed it when he got the plumbing diagram for the holiday.

If the damn Chamber of Secrets was hidden in the pipes, then it couldn't have been connected to the pipes when the school was founded - cast iron pipes were only available in 1800, and even if there were water pipes when Hogwarts was first built, they were probably lead or ceramic!

Later, I looked up some things about the school decoration that further explained this problem. Therefore, it must not be Slytherin himself who hid the Chamber of Secrets in the pipe! (Note)
Andrew had already figured it out. If there was a spell fluctuation, unless it was done by Slytherin himself or Dumbledore, it would not be hidden under his Transfiguration spell.

Sure enough - when he cast the spell to activate those beans in the range just now, his target was exposed.

"This way, Percy, and Nazarov."

Andrew called out to the two prefects as he checked.

This is a copper faucet with a small snake carved on the side of the faucet.

"here it is?"

"I don't know, but my Transfiguration can't affect it. I just feel that there is a difference here."

"Then I can't do that either?"

Percy asked after a moment's hesitation.

"No, I thought there would be a person or an alchemical device or something... But... This thing is more advanced than I thought... Wait, I thought of something."

Andrew's expression was solemn. "Don't leave, Percy. Keep an eye on Nazarov and don't communicate with those people. Forbid them to come in. I'll go inform the professor. Believe me, this is for your own good!"

"Keep an eye on Nazarov?"

Nazarov, the Hufflepuff prefect who came to help, pointed at himself, looking confused.

"That's right. Keep an eye on him. The news here cannot be leaked out. Not at all."

Andrew looked serious.

Only in this way can Ginny be implicated and the diary be caught in one fell swoop - although the snake has nowhere to escape and the diary is also caught in the jar, Andrew decided to play it safe.
