In the blink of an eye, it was already early the next morning, and Dumbledore still hadn't returned.

He was unreachable to anyone, including Professor McGonagall, the Vice-Chancellor and member of the Order of the Phoenix.

During the search for the castle, Snape was found unconscious in the Potions classroom, clutching a scale in his hand.

There were a lot of traces of battle left at the scene, including the blood of some kind of magical creature, a ripped out snake eye bead, and the snake's main fangs.

It is speculated that Snape encountered the basilisk and went through a difficult battle, successfully destroying two of the opponent's most threatening eyeballs and breaking the fangs.

"It's unbelievable, judging by the size of its teeth and eyes, this basilisk has at least a thousand years of life."

"Your Slytherin dean is really strong, and he can fight to this extent, and it looks like he has the upper hand."

An instructor from a clock tower is recreating the scene.

"Look, it was around the corner of the hallway that the first battle broke out here, and he used some kind of sharp cutting spell to blind the basilisk with great precision, and there was still liquid residue inside the eyeballs, and the two eyeballs, including a large part of the head, were really beautifully done!"

"I heard he's a master of potions? Maybe he'd been able to deal with similar snake tissues to be so precise, but this magic was actually the key to his victory. In the ensuing battle, the basilisk continued to lose blood, indicating that the injuries caused by this magic have the property of being difficult to heal, please forgive me for not being able to tell which one it is, similar effects are relatively rare. ”

This white-gloved lecturer looks fanatical and excited, and he is like a medical maniac.

After that, he cleverly took advantage of the disadvantage of the basilisk's inconvenient turning, diverted, and used various techniques that restricted the terrain in the dead corners, but the basilisk's skin hydrated ordinary spells could hurt it, and finally, he introduced the big guy into this classroom, where he knocked out its full mouthful of teeth, pulled out its fangs, and even had the energy to collect the basilisk's venom - wonderful tricks! He is a master of potions! ”

The lecturer fumbled for a long time in a pool of half-coagulated blood underneath, and finally found a palm-sized short-mouthed bottle with a lot of blood on it.

"That's it, he's tossed the basilisk enough to choke, and the venom taken from the living basilisk is the best quality."

"So, what about the basilisk now?"

Professor McGonagall bothered in her spirits, there had been so many things that had happened that night, that she could not cope with them for a while.

First, Harry Potter died in a duel, then the Dark Wizard invaded, and then it was discovered that the students of his own house had colluded to trick the teacher into stealing the dark magic from the forbidden book area, and when he returned to the castle, he found that Lockhart had been killed, and then an earth-shattering battle, and Slytherin Dean Snape fell unconscious.

Until now, there has been no count of how many places were destroyed during Snape's brief encounter with the basilisk, and how many students were accidentally injured during the night tour or watching the excitement.

The clock tower didn't stop and asked Hogwarts for an explanation.

However, Dumbledore, who was supposed to be the one who was supposed to be the leader, was not there.

Everything was on her shoulders alone, and now only she, the Deputy Headmaster, could call the shots at Hogwarts.

It's a pity that she's actually not young, and she still has to deal with so many troubles.

Merlin, why is there so much going on at Hogwarts this year?

Professor McGonagall sensed the malice of the world.

"Basilisk, that guy wasn't lightly injured, and he wasn't much of a threat anymore. Having lost its deadly sight, and fangs, and blood loss, I suspect it's dead. ”

The lecturer stood up and spilled a silver powder, and many marks appeared on the ground, which seemed to be slime that was difficult to find.

"Follow the slime to find the basilisk, it's so badly injured that it won't be able to escape far."

Eventually, they found a centuries-old water supply pipe at the opening of the hole.

"Look, this is a common design for medieval castles, I've seen something similar to it at Ghost Castle, but it's older here."

"The aristocracy of the time used groundwater, well water, spring water, and even condensate from the humid air to create a very complete water supply system inside the walls, which is still not obsolete today. Hogwarts seems to be a bit more advanced, with special magical maintenance, and it still works well after millennia. ”

"Actually, I've always been very interested in the water network of this castle, if I can ······· it"

Another lecturer seemed to be very interested in a similar architectural design, chattering in front of the large hole in the wall as if he had seen some precious architectural example.

Professor McGonagall finally couldn't help it and interrupted him.

"I beg your pardon········ I would like to ask what course do you teach? ”

Several lecturers on the side coughed and gestured with their eyes.

"Well, I teach magical architecture and engineering at school."

It was only then that he realized that this was not the right place to talk about his profession, and it was a bit of a joke.

"Before I came into contact with magic, I studied civil engineering at Southeast University in China, and I was very fond of architecture, especially in the wizarding world."

"I'm really sorry to delay everyone's time."

He stepped out of his seat, smirking and stepping aside.

"Professor McGonagall, there's a water pipe, and the basilisk looks like it's being transferred through these pipes all over the castle."

"Do you know where it leads?"

Everyone was gathered here, except for a few professors who were reassuring the students.

Professor McGonagall thought for a moment and shook her head.

"This was a long time ago, and until you find the blueprints of the Slytherin family's castle at the time, no one knows how the pipes were laid out."

"All I know is that the sewage is discharged directly into the bottom of the Black Lake, and this is how it has been going down for thousands of years."

You don't want to go down the drain, do you?

It's been used here for thousands of years, do you know how dirty the sewers are?

Even if there are house-elves affiliated with Hogwarts who follow the old practice and maintain them on time, it doesn't change the fact that it's dirty.

"Well, we're afraid we won't be able to find the basilisk unless someone knows where it's hiding."

"After all, it's such a long pipe··········"

The Muggle Studies professor said so.

For a moment, there was silence on the field.

The whereabouts of the basilisk must be traced.

Despite being blind and with its fangs broken, it was also a dangerous basilisk, and its body alone was enough to torture a student.

Indulgence is the biggest irresponsibility.

But what to do?

There's no way they're really going into these pipes that don't know where they lead, and they're playing hide-and-seek with basilisks.

"I know where the basilisk goes."

A voice spoke softly.

They looked over and somehow, Hermione was standing there.

"Hermione? Good girl, how did you end up here? ”

Professor McGonagall's first reaction was that there was another bear child who violated the rules for a night trip.

"Professor, I've found some information that might help you."

"Please come with me, and I'll take you to the basilisk."

As soon as she finished speaking, she turned and left.

"Fifty years ago, there was a big incident at Hogwarts, a Ravenclaw girl was found dead in the girls' bathroom, and it has been abandoned ever since."

On the way, she explained to the professor behind her.

"It turns out that the crying myrtle also died under the gaze of the basilisk."

Professor McGonagall had an epiphany.

Legends about the Chamber of Secrets have endured, and on that occasion the Ministry of Magic even sent Aurors and Strikers to inspect the castle for three days, but they forgot about the water pipes.

Coming to that toilet, Myrtle is no more, in fact, she will never come back, banished to an unknown place, even a ghost cannot find a way back.

On a copper dragon head to the left of the pool, they found a small dark gold snake carved into the side of the dragon's head, carved lifelike.

"That's it, someone used to speak here in snake language, Myrtle told me, she heard something like hissing."

Several professors examined for a moment and nodded to each other.

"Good girl, thank you for your help in adding fifty points to Gryffindor."

Professor McGonagall gave a rare smile.

"Leave it to us adults, go back and have a good rest, we probably won't be able to attend classes today."

"If you want, you can go and inform the prefects to spread the news, until we are done with the matter here, all the students cannot go out alone, and must act collectively."

"I will, Professor."

Hermione looked like usual and nodded at her.

She really needs to take a break, and there will be a lot of trouble in the future!

After getting this crucial news, the entrance to the secret room was difficult for so many professors.

It was not practical to learn snake language on the fly, so Professor McGonagall casually turned the toilet door into a slender python and ordered it to come forward.

The python spits out the snake letter and hisses at the faucet, which is probably something like "get out of the way", "open", "get out of the way".

So, the passage opened, and some people followed, and another people answered on it.

The secret room, which has been dormant for fifty years, once again welcomes a new visitor.

This time, it will be the time to solve this big problem once and for all.

In the secret room, they found the dying basilisk that had lost too much blood.

On top of that, there were some Slytherin's experiment logs and the like, but unfortunately the valuable ones had long since been taken away by Tom Riddle.

They brought back the basilisk's corpse and eventually sealed off the vault again.

"Now, a problem has finally been solved."

However, the duel was not over yet, and Professor McGonagall only felt tired.
