Stumbled all the way to the door of Luwei. The process was very unsmooth, first bumping into Lady Loris, and then bumping into Peeves. Fortunately, the three of them were more clever and came over without danger.

But I saw that the door of Lu Wei's room had been opened and a crack

"Looks like we're a step late" Facing the half-open door, Harry realized that the front could be very dangerous. He looked back at Ron and Hermione, "If it's too late to back down now"

"Don't be stupid, of course we'll be with you!" Ron replied immediately

"But Harry, knowing that Quirrell was already in. Shouldn't we come with Ivey, it's safer. For the safety of the lives of the three of them, Hermione thought more thoughtfully.

"No, I can't. We don't know what's going on inside, I'm afraid it's too late. Ivey said that she would go to the principal's office to take care of Phoenix in the evening, and Betty would definitely be with him. If you want to find them, let alone whether they will be discovered by Filch or others, the time it takes to go back and forth alone cannot afford to delay. Maybe by the time we ventured over, Quirrell would have already done it. "It's not like Harry hasn't thought about asking for help

"In that case, don't think too much, just bite the bullet" Ron is a rough man, as long as he is not afraid, he dares to rush.

"Fluorescent Scintillation"

The three of them quietly opened the door after lighting the lamp and crept into the room

The sound of the flap pulling stimulated Lu Wei's nerves, and although he couldn't see it, he could smell it. It barked low and shook its nose frantically.

"Look at its feet," Hermione pointed in a whispered reminder. Harry and Ron barely heard

"Harp? It must have been Quirrell's stay," Ron said

"Shall we blow it?" Harry pulled out Hagrid's Christmas present

"Don't bother, look at me," Hermione pulled out her wand

"Vocal Music"

The light flashed from the fallen harp, and the body rose instantly, and the strings began to pluck themselves. Soon, a beautiful melody filled the room. Louwey's vicious eyes narrowed and became slouched, it stopped barking, shook a few times, and then its knees went limp, and it fell to the floor, and fell into a deep sleep.

"That's amazing!" Ron complimented. He regained his normal voice

"Didn't Ivy say that we should learn more practical magic when we were talking about it," Hermione took for granted

"You think everyone is like you, we're already busy just studying for exams," Ron was unhappy with her relaxed tone

"So none of you learned?" Hermione looked at them incredulously

"Who said I didn't learn a single one! Who to look down on! I learned one anyway," Ron retorted

"Me too," Harry said

"Really?" Hermione looked incredulous

"Alright, let's go down," Harry digressed

Ron opened the cellar entrance and suddenly found a wreck in the corner. If you look closely, it's all gears and shafts, "It looks like a broken music box"

"What's so nice about a pile of garbage, go down!" Hermione urged

The trio jumped down and landed on a black vine. Here they were confronted with a devil's net, and the layers of vines twisted around the three of them like pythons. Harry and Ron struggled desperately at first, but the more they broke free, the faster and tighter the vines became entangled. Moment of truth – or Hermione.

She recognized the devil's net at a glance, and immediately stood still and sank, and then promptly reminded the two men to relax their bodies and not struggle. Harry was okay, he listened to the command, and quickly got out of the situation. Ron was more of a problem, seeing his companion disappear, he couldn't relax at all. In the end, Hermione, who was still familiar with the habits of the devil's net, released a beam of light and saved him.

Keep going. They made their way through the hallway to a brightly lit room. The vaulted room, with a very high ceiling, is filled with countless key-like birds, flapping their wings and flying slowly in the air. On the opposite side of the room was a heavy door, and on their side were rows of broomsticks.

Seeing this, the situation is very clear. As the youngest Seeker in a century, Harry stood up for it. He also has a veritable ability to fly. Chased by a group of keys, he not only finds the target, but also successfully catches the key with its wings hanging and opens the door.

Coming to the next level, which is Ron's home arena, a large game of live wizard chess. He charged into his own battleground, spotting Harry and Hermione's perilous situation on several occasions and helping them out of the siege. In the end, he sacrificed himself and retired. Until the moment when the White King threw away his sword, as a knight, he fulfilled his mission perfectly.

After clearing the level, Hermione hurried forward to check on his condition

"He's fine, just unconscious"

"It's the third level. Don't know what's next? Harry worried

"Hagrid said that all the professors were involved in the defensive setup. That devil's net must have been set up by Professor Sprout; The key to flying is apparently Professor Flitwick; This game is supposed to be Professor McGonagall's Transfiguration. All that's left is Snape and Quirrell," Hermione sorted out the message

"Let Ron rest here first, and we'll move on."

The two then came to a door

"Let's go straight in," Hermione pushed the door open

A disgusting stench came to my face, and the pungent smell made my eyes so bad that I couldn't open my eyes. In the center of the room lay a troll, its head cut open, and its blood mixed with its brain and body flowed to the ground.

"This is Quirrell's defense," Hermione whispered, pinching her nose

"Why not Snape?" Harry asked

"You can see it from the previous levels. Professor Sprout's Herb class, Professor Flitwick's Levitation Charm, Professor McGonagall's Transfiguration, these are all part of our class. In response, Professor Snape would test his knowledge in Potions class, and Quirrell would be the Dark Arts Defence. Hermione gave him a blank look and explained

"So—at the Halloween feast, those trolls were also released by Quirrell." It dawned on Harry

"Yes. Here's what I guess happened: that night, Quirrell unleashed a lot of trolls, causing a commotion. He took the opportunity to go to the fourth floor and wanted to steal the Philosopher's Stone. At that time, he had already figured out the method of passing through Lowe from Hagrid's mouth, and the defenses were all arranged by the professors together, and he knew how to crack it. Thankfully, Professor Snape saw through his ruse. Didn't you say that Snape was scratched on the calf that night, probably by a mistake by Laura when he stopped Quirrell. Hermione spoke all the conjectures in her mind

"According to you, isn't the Philosopher's Stone very dangerous! Quirrell may have already done it! Harry grew more and more worried

"Don't worry," Hermione was sure, "not just the professor, but the principal." Dumbledore's defenses weren't going to be simple. ”

"Also," Mr. Chancellor is always reassuring

"Let's get ahead"

"Well, here's the level that Professor Snape has laid out."
