Harry Potter followed Professor McGonagall to the first floor and the basement.

Harry's face turned pale when he saw that the destination was actually the bathroom where the three of them had secretly made the compound potion...... At this moment, he thought that they had stolen Snape's medicinal materials and prepared forbidden drugs.

McGonagall...... Professor......" he stammered.

"What are you stopping for!" Professor McGonagall said anxiously, "Headmaster Dumbledore is still waiting for you!"

Professor McGonagall's impatient tone was interpreted by Harry as harsh.

Hearing Dumbledore's name, he staggered to even walk.

Could it be that Professor Dumbledore is going to be angry and expel himself because of this......? It was estimated that in ten minutes, he would be packing up and going out, and what would the Dursleys say when they saw him at the gate?

Walking into the bathroom, he was surprised to find that Professor Flitwick, Professor Sprout, and even Professor Snape were all there, in addition to Professor Dumbledore.

The door to the compartment where the cauldron and the remnants were kept was still closed, with no sign of opening.

"Good afternoon, Harry!" Professor Dumbledore said gently, "There's one thing, maybe I'll have to ask you for a favor!"

"Help?" Harry couldn't help but breathe a sigh of relief, seeing Professor Dumbledore like this, it didn't look like he would have been expelled if it wasn't for the Polyjuice Potion.

"Come over here!" Professor Dumbledore patted Harry on the shoulder, signaling him not to be nervous.

Harry nodded, and did as Dumbledore had commanded, bending down.

With a bang, the bathroom door was pushed open!

Two second-graders barged in.

"Miss Granger, Mr. Weasley!" Professor McGonagall frowned.

Harry's face changed suddenly, and he desperately glanced at Hermione.

Unfortunately, Hermione's attention had been on Professor McGonagall and Professor Dumbledore since she entered the bathroom.

"Professor McGonagall, it wasn't Harry who did it, I did it!" Hermione's tone was like a cannon, "I came up with the idea of borrowing books in the forbidden section to prepare a polyjuice potion, I lost the dung eggs from that Potions class two months ago, and I also stole the bicornus powder and the skin of the African tree snake from Professor Snape...... If you want to punish me, you can punish me, and it has nothing to do with Harry and Ron!"

Hermione's idea was simple, Harry and Ron had already taken a big credit since the start of school, and if anything went wrong, she might be expelled, and she had to take it all down, at least Professor McGonagall still liked her, and at least she wouldn't be fired for a big mistake.

Ron gasped for air beside her, but didn't have time to stop her.

In the bathroom, the scene became a little awkward.

Professor McGonagall's face turned grim with anger.

Professor Flitwick and Professor Sprout looked at each other.

Professor Snape froze for a few seconds before he could react.

"Very good...... Granger ......" Snape sneered, "Now I know!"

Looking at Harry's loveless expression, and looking at the reactions of several professors, Hermione suddenly realized that she was in trouble.

"What's wrong?" a Defence Against the Dark Arts teacher walked in, breaking the awkward atmosphere inside, glancing at the crowded bathroom, "I remember it was an abandoned girls' bathroom......

"Oh, Headmaster Dumbledore...... Merlin, you're back!" Gilderoy Lockhart shouted with excitement on his face.

"Good afternoon, Gildero!" Dumbledore greeted Professor Lockhart with a smile, "We just discovered the Slytherin Chamber of Secrets, would you like to break into it?"

"Slytherin's Chamber of Secrets......" Professor Lockhart's face changed suddenly, but he immediately changed his expression: "I'm honored...... No, I mean, I've known for a long time that this bathroom is a Slytherin chamber, and I've been planning to get rid of it, but I haven't had time lately......"

Dumbledore ignored him and turned his gaze to Professor Snape, "Severus, at this time, maybe we shouldn't be paying attention to the minutiae!"

"The minutiae?" Professor Snape sneered, "Well, if you insist, Dumbledore!"

"Of course, it's just relative!" the expression on Dumbledore's face returned to seriousness, "Miss Granger, I hope you can come to my office tonight, and we can have a good cup of Prince of Wales tea together, and near the spiral staircase on the top floor, before a gargoyle, the password is 'lemon ice cream'." ”

"Yes, Professor!" Hermione nodded apprehensively.

"Then let's get down to business!" Snape snorted coldly, "Potter, come here...... See the side of this copper dragon head, carved with a small snake...... Say a few words to it. Say a few words in a parseltongue!"

......

The faucet emitted a dazzling white light and began to spin rapidly.

Then the pool moved, and they watched as it slowly disappeared from view, revealing a pipe that was so thick that a man could get in.

"It's amazing!" Gilderoy Lockhart couldn't help but exclaim, but after glancing at the unkind eyes of several colleagues, he quickly feigned a deep expression.

"Looks like you can only accommodate one person at a time!" Dumbledore smiled, "Gildero, or you can ask first; as our Defence Against the Dark Arts teacher, haven't you been looking forward to destroying the Slytherin monsters, and now it's time for you to do your duty!"

Professor Lockhart had a long mouth and didn't know what to say.

Snape kicked him lightly from behind, only to hear a scream and Lockhart fall.

Several other teachers looked away from them, pretending they hadn't noticed anything.

Harry was about to follow Lockhart and get into the pipe, but was stopped by Snape, who just glared at him coldly before jumping into the pipe for the second time.

One teacher after another and students got into the pipes...... Professor McGonagall was going to let Ron and Hermione go back to the Gryffindor common room, but Professor Dumbledore stopped her, agreeing to let the two second-year students join the hunt.

It felt like a swift rush down a dark, slimy, endless slide, with their tube twisting and turning, steeply incline all the way down.

After a few minutes, they emerged from the mouth of the pipe one after another, and fell to the wet ground with a thud.

It was a dark stone tunnel, large enough to hold several people standing in it.

They may have reached miles below the castle.
