When Harry Potter woke up, he found himself in a very strange space. He lay in the middle of a stone platform about 30 feet long and wide, surrounded by a dark space that could not be seen, except for the point of light that glowed like fireflies floating on the platform he was on.

Harry stood up and shook his dazed head, then remembered that he had left the common room on the basement level, so he took his invisibility cloak and set off for Malfoy. Later, he saw Malfoy push the door and enter the reading room with Zhang Xu there, so he quietly followed. As a result, as soon as he walked into the reading room, he lost consciousness with a "biu", and when he woke up, he found himself in this strange space.

"Zhang, are you there? What's going on?! Harry, who had used the word "loud," shouted.

Harry was sure that his current situation must be related to Zhang Xu.

It's just that Harry didn't get any response after shouting a lot of words, and just as he was wondering, he heard a "boom" sound coming from his head

Harry looked up and saw that in what had been a dark mass of space overhead, a stone ceiling covered with spikes like a hedgehog's back was slowly but surely pressing downward.

If he didn't find a way, Harry thought he would be a hornet's nest in two minutes.

After trying a few spells to no avail of the ceiling, Harry immediately ran to the edge of the platform and looked down.

Standing on the edge of the platform, Harry saw a black platform floating about three stories below, and it wasn't hard to see if it was too difficult to jump over it.

Without much thought, Harry took a few steps back and jumped onto the platform with a run-up.

After landing safely, Harry had to be glad that he had learned a Levitation Charm to create a Slow Fall Charm, otherwise he would have choked on him from such a high height.

Harry had barely been on his feet when he heard the sound of stone shattering overhead, and he looked up to see that the platform he was standing on had been smashed to pieces by the ceiling, and then the pieces had fallen down into the endless darkness below.

Harry didn't know what was in the darkness, but his instincts told him it was best not to jump down.

At that moment, a circle of big-headed monsters suddenly appeared around the platform where Harry was.

For Harry now, a few Dementors weren't enough to fill his teeth.

After dealing with the big-headed furry, Harry walked over to the platform and saw another platform appear below.

At this time, Harry could already be sure that this inexplicable and dangerous space must have been Zhang Xu's ghost. Although he didn't think that Zhang Xu would kill himself, he could still do it by lying in the school infirmary for half a year or something.

Harry didn't hesitate to jump onto the third platform.

After driving a transformed werewolf off the platform and falling into the black mist below.

Seeing that the spiky ceiling was not far from him, Harry hurried to the edge of the platform, and found that the platform below him was covered with the same spikes as the ceiling, while the normal platform was about ten stories high from him.

After Malfoy left the reading room, Zhang Xu also left, but he did not go back to the dormitory to rest, but went to the E-13 classroom on the fifth floor.

The classroom was empty except for Friday night, which Dumbledore used to help students with their homework.

When Zhang Xu came to this classroom, Dumbledore was already sitting in front of the table, and Zhang Xu sat down on the chair opposite Dumbledore after saying hello.

At this time, there was a crystal ball the size of a rice cooker on the table in front of the two of them, and the crystal ball showed Harry Potter who had personally experienced "A Man Will Go One Hundred Floors Hogwarts Edition".

"How's Harry doing?" Zhang Xu asked.

"He's already down to the twenty-third floor." Dumbledore replied as he shoved the plate with cockroaches on the table in front of Zhang Xu.

Zhang Xu pretended not to see Dumbledore's movements, and then took out a piece of rainbow mousse and ate it himself.

Dumbledore shrugged his shoulders and pulled the cockroach pile in front of him.

Harry, who was now on the twenty-fourth floor of the platform, surrounded by zombies with a bucket on his head, wondered if he would have gone crazy if he had known that the two initiators of his suffering tonight were sitting in the classroom and eating snacks while watching him fight hard.

"Do you think Harry will be able to make it to the end?" Zhang Xu asked Dumbledore.

"I don't think it's too much of a problem." Dumbledore said.

After a while, Dumbledore added, "If Harry can complete this challenge tonight......"

"I'll lend the Resurrection Stone to Harry as agreed." Zhang Xu said.

After the two of them finished speaking, they refocused their attention on the crystal ball that showed Harry's actions.

Harry, who had just wiped out the zombies, was lying on the platform, gasping for breath, as he had just made his way to buy himself some rest.

It's just that as the number of floors increases, Harry has less and less time to rest.

The consumption of physical strength and magic is one thing, the main thing is that he does not know where the final end is. Battles without knowing the goal and the conditions for victory are extremely testing of one's will, and can give up because one cannot see the goal.

It didn't take long for Harry to see whose handiwork this routine was too strong, and he guessed that he would definitely be able to get out if he "looked for death", but what supported him at this time was that he wanted to see where his limits were.

After a while, Zhang Xu watched Harry run around as he was being chased around by the rotten kun on the fiftieth floor and asked, "Professor, what kind of opening conditions do you plan to set for this 'dungeon'?" ”

"I'm going to have students who come out late at night to experience it." Dumbledore replied.

In the past, Zhang Xu introduced the meaning of "copy" to Dumbledore in a chat, and it turned out that Lao Deng was quite interested in this method of fighting monsters and upgrading. The result of Lao Deng's interest was that he led a group of people to start tinkering in Hogwarts Castle, and Zhang Xu was assigned the task of writing a "copy" script by him.

And now Harry Potter, who is being chased around by a group of Fallen Demons shouting "Lacanixiu", is the first "dungeon" of Hogwarts to experience it.
