Hogwarts founder returns to campus

Filch was already standing in the corridor on the fourth floor. As the administrator of Hogwarts, he had many years of experience in fighting wits and courage with students.

He knew what kind of temptation would emanate from the corridor on the fourth floor at this time, inducing those students to explore here.

Just now he heard a loud noise coming from the direction of the fourth floor. If it wasn't because the door lock was intact, he would have thought that some students had already invaded and wreaked havoc inside.

At this moment, Mrs. Norris, his pet cat, seemed to smell the smell of troublesome students again.

If the people who came here were lower grade students, he would definitely let them try the feeling of hanging people with iron chains.

Since Dumbledore took charge of the school, because he did not advocate strict teaching, the iron chains that were once used as punishment tools have been dusted for a long time.

He had to spend his private time tending to the chains and oiling them to ensure they could be used in the future.

He followed Mrs. Norris to a corner, only to find that Mrs. Norris was lying on the ground, trembling and desperately playing with an aromatherapy ball, licking and kissing constantly, and humming to represent pleasure.

He had never encountered such a situation before, even if he gave Mrs. Norris an extra meal, he had never seen Mrs. Norris act so crazy.

"Passed out!"

A red light suddenly shot towards him from the corner, and before he could react, he had already lost consciousness...

"Stunning Curse!" Hermione grabbed Cassandra's clothes, "You actually used a Stunning Curse on Filch! How did you know how to do this?"

"Good job! I'll know how to deal with Filch next time!" Ron's tone was filled with excitement, "But what is that thing that fascinates Mrs. Norris?"

Cassandra put the wand into her pocket, and said with a smile on her face, "Nepeta, Muggles call it catnip, is a herb that can drive cats crazy, but it has no side effects."

"Let's go! I think my headache is getting worse!" Harry's forehead was covered with cold sweat, and the sweat even wet his clothes.

This time the headache was unprecedentedly severe, which made him feel dizzy, and now he is relying on his will to hold on.

When he came to the wooden door, Harry found in despair that there was no movement inside, but the lock was intact.

"Snape has already gone in, and he may be about to get the Sorcerer's Stone by now!" Harry's face turned pale again, "He is too dangerous, you can actually go back, help me notify Professor McGonagall!"

"What nonsense!" Ron pushed the door open.

The four hurried into the room, and they were horrified to find that the room had been extensively damaged.

Fragments of musical instruments were scattered on the ground, the floor was lifted, and the walls were full of cracks. The three-headed dog Lu Wei kept a forward posture.

It wasn't until a closer look that Lu Wei's body was covered with scars, but the blood was a strange gray-black color, like the color of cement.

"Black magic, the skin of the three-headed dog has strong magic resistance, and it can only be petrified by cursing it through blood." Cassandra's face was ashen, "How dare you do such a thing! Unforgivable!"

She began to chant spells on Lu Wei, and various healing spells made the blood on Lu Wei's skin gradually return to normal, turning dark red.

Then they took out the glass bottles from the small bag. The labels of these bottles and jars were somewhat recognizable to Hermione and the others, such as white fresh, silver powder and so on.

They haven't learned these materials yet, such as Motra's tentacles juice, hawthorn wood powder, etc.

Cassandra even took out a self-igniting stirring crucible, and added the ingredients into it one by one while chanting the spell.

"The difference between people..." Ron rubbed his temples, "Hermione, can you understand what she's doing?"

"Probably brewing healing medicine?" Hermione's eyes flickered, her tone was uncertain, "Lu Wei is her friend."

"No wonder he and Hagrid have so much in common." Ron said with a knowing expression.

Cassandra's movements were extremely fast, and she had completed all of this in less than a few minutes, and then said with a long sigh of relief: "Go on! This still needs to be boiled for at least three hours."

Harry hurriedly opened the trapdoor, his condition was even worse now, and he fell into it in a drowsy state.

Ron quickly grabbed Harry's clothes, and the two of them fell into the hole together.

"So impatient?" Cassandra muttered, took out a blue-green egg sac from her pocket, grabbed Hermione's hand, and the two jumped into the hole together.

"What are these? I feel like I'm strangling!" screamed Harry and Ron.

"Devil's net! Hermione, use the Fire Curse!" Cassandra ordered, "Luminescence flashes!"

During the fall, Hermione almost missed her wand, but soon she felt something soft and sticky under her feet, supporting her and Cassandra, and finally landed smoothly.

"Fire!" Hermione who landed finally seized the opportunity to cast the Fire Curse, and blue bellflower-like flames gushed out of her wand.

Then Harry and Ron felt the sense of restraint in their bodies gradually disappear, and finally left their bodies, curled up in the dark place in the corner.

With the help of the Illumination Charm, they discovered that there was a charred black hole next to it.

Fortunately, Harry and Ron fell into the entrance of the cave. Otherwise, according to the original direction, they might not be bound by the devil's net, but a hard stone slab.

"You're waiting for us here, you're in a bad state." Ron said, supporting Harry.

"No...I have to go." Harry refused, sweat dripping from his brow to the ground.

"Stay safe!" Cassandra suddenly pointed her wand at the scar on Harry's forehead, and recited a spell.

Harry's complexion improved at a speed visible to the naked eye, and his eyes could finally be fully opened.

"What did you do to him?" Hermione asked in surprise.

"A protective spell that deflects evil spells. I feel like Harry is being cursed continuously by something, so I temporarily cut off this connection." Cassandra said with her wand back.

"Let's go quickly! If it's a little later, Snape might get the Philosopher's Stone!" Harry took the lead and ran to the front.

The four of them went down the long ramp, and at the end of the ramp was a brightly lit room, which was also in a mess.

Numerous keys were scattered on the floor, and a large hole had been blown open in the door at the end of the room.

"And the temperature, it seems that Snape is not much earlier than us!" Harry carefully picked up the key on the ground, feeling the remaining warmth on the key.

After passing through this room, what I encountered was still ruins. Countless statues were smashed, and I could vaguely see a huge wizard chess board here, and those statues were chess pieces.
