Everyday players at Hogwarts.

At 5 o'clock, the three Harrys stood in front of the corridor. Under the invisibility cloak, they looked at each other.

The door has been opened a crack.

"It shouldn't be. This was not the time in my dream."

"Could it be that Quirrell didn't succeed? He failed, and then at night Voldemort's collaborator - the mysterious silver-eyed wizard came back to steal the Philosopher's Stone?"

"Quillot's failure was probably because Voldemort was not with Quirrell to avoid Dumbledore's sudden attack!" Harry whispered to Ron and Draco.

Seeing the half-open door, the three of them understood that someone had passed through Lu Wei.

Harry said to Draco and Ron under the invisibility cloak: "Draco, you go to Hagrid first and ask him to write to Dumbledore. Ron, if you want to leave, I won't blame you, You can go to Professor Snape and tell me I'm in danger."

"Well, maybe Dumbledore just pretended to leave and waited." Draco joked to reduce the tension.

And Ron gasped, "Don't even think about leaving us."

"The three of us want to be together!" Draco emphasized.

"Don't you understand? If Quirrell gets the Philosopher's Stone, Voldemort will come back! Haven't you heard what was going on here when he wanted to dominate the world? If he succeeds, Hogwarts will not It will exist!”

"I don't want to abandon you, I want you to find helper, Hagrid, Snape or Dumbledore will do!"

"If it's just the three of us, if we fail, not only will we lose our lives, but our family's lives will also be lost because of our failure!"

"After this, he will burn the school to the ground or turn it into a school dedicated to teaching dark arts! Can't you see why I want you to leave?" Harry glared at them angrily.

"We don't need to go there in person to report the news. Why do you think I just spent so much time checking whether Quirrell is still there?"

"I wrote a letter by the way and made three copies. I have already told Goyle and Crabbe that if I don't come back within an hour, let them find Hagrid and give them the letter I wrote in advance. Give it to Hagrid, and give the other two letters to the owls for our Dean and Dumbledore respectively!" Draco said shrewdly.

"Draco is really yours." Ron couldn't help but call out his name. Draco was obviously not used to it and shuddered, "You should call me Malfoy, Weasley."

Harry had no excuse for them to leave now.

As Harry opened the door, Lu Wei, who had been listening to the conversation between Harry and the three of them, suddenly started barking.

Although it couldn't see them, all three of its noses were twitching and sniffing frantically toward them.

But Harry had already prepared everything. He took out the flute that he had enchanted, and the flute kept playing something that could barely be called music automatically.

The big dog's eyes began to droop downward.

Slowly, the big dog's barking stopped - it swayed a few times, its knees softened and it knelt down, then plopped down on the floor and fell into a deep sleep.

"Look, there's a harp there. It turns out to be Quirrell or someone else."

"If it's Hagrid or Dumbledore, they won't be able to use it." Ron's face became serious.

"Did you notice that we were talking so loudly outside just now, and Lu Wei didn't react at all?"

"Also, Lu Wei has been calling for so long, why hasn't anyone been attracted outside? The fourth floor is always quiet when I pass by during class."

"There must be some soundproofing magic here." Draco guessed as he followed Harry and Ron towards the trap door.

"It stinks, why don't Lu Wei wash it off." Ron covered his nose and opened the trap door. They had already taken off their invisibility cloak.

"Nothing could be seen in there - it was pitch black - and there was no ladder to get down."

"Looks like we have no choice but to jump." Harry said as he looked at the dark passage, "I'll go first. I'll know there are many obstacles. It's very effective in jumping from high altitudes."

"I'm using the levitation spell down below." Harry thought of a way to break the situation in just a short moment.

He had thought about turning the ground below into a haystack, but this would apply magic to the outside world. If the object applied was not an ordinary ground, it would be a useless effort.

This made Harry reject the idea and instead used the curse of obstacles. After he knew that Ryan could fly, he thought about related spells, and finally saw a different use of this curse in Atlantis. .

Ron and Draco nodded, with expressions of admiration on their faces.

"Obstacles!" This spell mainly slows down the object on which the spell is planted. Both spells and objects can be used.

And Harry now imagined the air below him as an enemy.

It went smoothly. Harry fell slowly as if he were in a fluid, and soon touched the ground.

It was obviously summer, but the surrounding air was still very cold and humid, and the ground was very soft, as if he was standing on some kind of plant.

This is Professor Sprout's line of defense!

It needs to grow in a moist and cold environment, needs a dark environment, and is vine-like - Devil's Net!

No, it shouldn’t be that simple. Could it be that this plant has been modified?

In such a dark environment, wizards will use spells such as fluorescent flashes. At that time, the plant will entangle according to the light, strangle or trap the wizard who breaks in without permission?

"You jump first, it's a soft landing." As soon as Harry finished speaking, Draco and Ron also jumped down.

"Oops, the devil's net is really invisible. I didn't feel it at all, but it was wrapped around my legs." Harry made a grimace.

"Devil's Net? Even I know it's afraid of sunlight, and flames are better." Ron was already wrapped around his ankle.

"Weasley, you idiot, it must not be that simple, it must-" Draco closed his mouth mid-sentence.

The scene in front of him shocked both him and Harry. Ron conjured up blue bellflower-like flames that Harry had often used to warm his hands.

In just a few seconds, the vines loosened their grip on them.

It shrank away from the light and warmth. The plant twisted, twitched, and hid in the corner.

"What are you sure about?" Ron kept the flame alive.

"It's nothing, maybe the previous Quirrell has broken through the transformation." Harry comforted himself, he didn't believe it was really that simple.

If it were true, wouldn't his struggle just now be the same as Ron's (fool).

"Unexpectedly, Professor Sprout's line of defense is what we taught in our first-year class." Draco wiped his cold sweat.

"Yeah, luckily I paid attention to the class." Ron said proudly without hearing the implication.

Harry and Draco looked at each other and decided to let Ron be happy first. Such a mood would be more conducive to later levels.
