Su Yun sighed, he still hadn't been able to get much useful information from Zhou Yi's mouth in the end.

He continued to wait, according to what he knew, the madman who didn't know the name behind the red door, as long as he didn't knock on his door, he wouldn't come out, and the "fool" Xu Youliang behind the blue door should be sleeping.

So what Su Yun was waiting for was the "heart demon" Tianyu in the black door.

He didn't know how long he waited, but he didn't see Tianyu walk out of the door, in order to prevent himself from being too bored and leaning against the corner to fall asleep, Su Yun counted his pulse measurement time.

an hour.

Two hours.

Three hours.

Four hours.

Five hours.

Just when he was calculating that the fifth hour was approaching the sixth hour, suddenly his eyes went dark, and he lost consciousness inexplicably!

There was only one sentence left in his heart: "it".

When he woke up again, Su Yun was already lying on the bed again, and the first thing he did after waking up was to rush to the door and enter the door opening code "5189" in his memory.

Wrong password!

Su Yun's heart suddenly cooled.

He roughly knew a new rule, which was that there were only six hours in a day, and six hours after waking up, some kind of special "reset" mechanism would be triggered immediately.

Su Yun calmed down and told himself that there was still time to go, and there was still thirty days in the plot world at a time, and he still had a chance to try, although now his head was messed up and he had no clue.

He started the password attempt, starting with zero-zero-zero.

Four hours later, Su Yun broke the code.

He then lifted the bedside table under his buttocks, smashed open the window, and held a piece of sharp glass in his hand as he had done yesterday.

There were still two hours left, and Su Yun told himself in his heart that within two hours, he had to trigger the backtrack.

In order to prevent accidents, he took the initiative to cut his wrist before going out, so that he could ensure that he would die within two hours and trigger the backtracking stably.

With the blood stains on his wrists, Su Yun walked out of the room.

There were no dead people outside the door, red, black, blue, and the three doors were tightly closed, indicating that the madman, the demon, the fool, the three people did not go out.

Su Yun had already tried, the door that had been opened could not be closed again, even if it was covered, it would be difficult to close, the door would slowly open by itself, even if there was a bedside table behind the door, it was useless.

And green, purple, yellow, white, the four doors are open at this moment.

As usual, Ora sat in the doorway, her hair disheveled, but it was a little different from the last time Su Yun saw her, her eyes were bloodshot, and she looked even more terrifying.

Su Yun came to Euler without fear and said to Ora, "Hello, Miss Ora......"

"Miss, your mother! Your whole family is a young lady! Ora suddenly stared at Su Yun and raised his head and scolded, "Get out of the way for the old lady, otherwise be careful of the old lady and I will strangle you!" ”

Su Yun took a few steps back, looking at Ora who looked like a mad demon, his eyes narrowed slightly.

It seems that Euler seems to be a little abnormal today, just like yesterday's Zhou Yi.

Her eyes were bloodshot, and it seemed, it seemed, that she was crazy?

Su Yun didn't ask any further, after all, the number provided by Euler, or the number of days, was not of great help to him.

He cautiously walked downstairs.

There was blood and the smell of blood on the stairs again.

Su Yun cautiously walked down the dark stairwell, and sure enough, he stepped on a corpse at the end of the stairs.

He now has a wrist injury, so he didn't try to carry the body because it would speed up his bleeding.

He ripped the corpse off of its clothes, then walked back to the middle of the stairs and made out the color of the clothes by the light coming from upstairs.

Although most of the clothes were stained red with blood, it was still visible through some parts that were not stained red, and it was once a yellow garment.

In this way, Master Zhou Yi was killed by someone on the stairs again.

Someone should have asked Zhou Yi a question, but he didn't want to pay, so he killed him with his backhand.

Su Yun threw down his clothes and continued to walk downstairs.

The downstairs was still as dark as he remembered, but this time, there was a faint smell of smoke in the darkness.

Something seems to be on fire!

Su Yun quickened his pace, moving in the direction of the library in his memory, and soon saw a dazzling firelight, he pushed open the door of the library, only to see that the fire inside was fierce, the smoke was billowing out, and he couldn't see anything clearly, Su Yun lowered his body, only to find that there was already a charred corpse lying on the ground.

Because the body was charred throughout, he couldn't tell which one it was.

Su Yun explored the fire for a while, and then couldn't help but retreat from the thick smoke and high temperature.

Faced with the smoke billowing from the entire floor, he wanted to retreat to the upper floor first to take a breath.

He walked in the direction of the stairwell, only to find that an invisible barrier had appeared at the door of the stairwell, just like the one that had prevented them from exploring the downstairs on the first day.

I can't go back after going downstairs!

For the first time, Su Yun learned a rule.

No wonder someone set fire to the second floor.

Those who came down from the upper floors could not immediately find a way to the third floor, and they would have to die of smoke from the fire, because they would not be able to go up or down.

This also explains why the fire below has been burning for so long, but there is no smell of fireworks upstairs, if it weren't for the one-way barrier here and the fire downstairs, the upstairs would have been full of smoke.

After understanding this, Su Yun safely slashed the wrist on the other side with a glass piece, and then continued to grope in the dark, blood loss and poisonous smoke, it is estimated that it will not take long to trigger the backtrack, using this time, he can fully explore the situation in this layer.

Maybe in the darkness, there are other people who are like themselves, sealed in poisonous smoke.

However, before he fell into a coma, he searched the entire second floor, and found no other body.

Unless there are other bodies hidden in the library, it can be assumed that only one person is dead on the second floor.

I don't know how long it took, Su Yun woke up in bed again.

He sat up on the bed, then slammed down on the door and typed the code in.

The password is correct.

Su Yun breathed a sigh of relief.

He opened the door and walked outside.

As expected, the red-eyed Miss Ora was the first to come out of the room after him, and sat down in the doorway, still clasping her hands on her knees.

Su Yun tried to walk over and said tentatively, "Miss Ora." ”

Ora's eyes glared in Su Yun's direction and shouted, "Miss, your mother! Your whole family is a young lady! Roll away for the old lady, or be careful of the old lady and I will strangle you! ”

Exactly the same words.

Su Yun was almost certain that Euler's transformation did not happen on the current day, but at some point in time before, because he had gone out early enough this time.

But he remembered that yesterday, Euler was still normal.

Why is it suddenly like this today?

There must be something strange in this.

Just as Su Yun was thinking, the purple door opened, and the "director" Moriarty walked out of the room with a normal face, and when he walked in front of Su Yun, he said without changing his face: "Hello." ”

Su Yun took a deep breath, returned to the room, smashed the window with the bedside table, and took a piece of broken glass in the palm of his hand.

First of all, he had to find out who set the fire on the second floor yesterday, and who was the one who was burned to death.

His mind began to slowly analyze.

According to the picture he saw yesterday, only Ora, Socrates, Moriarty, Zhou Yi, and himself opened the door, and the other three people, Xu Youyou, Tianyu, and the unknown madman Mr. None of them opened the door.

Zhou Yi was thrown to his death in the stairwell.

Then, in the end, only one of Moriarty and Socrates could be burned alive in the library on the second floor, and the other who survived managed to escape to the third floor.

Looking at the current situation, Moriarty went down ahead of schedule and took the lead, so there is a high probability that it was Socrates who burned to death in the library in the end.

Su Yun hesitated for a moment and decided to go downstairs first to get in touch with Moriarty.

Just as he reached the top of the stairs, the yellow door opened.

Su Yun thought about it for a while, and finally didn't choose to meet Zhou Yi, he needed to know how Zhou Yi was killed in the end.

He originally thought that Moriarty had thrown Zhou Yi to death, because Moriarty had admitted it before, but this time, Moriarty went downstairs ahead of schedule, according to the principle of irreversible movement of the floor, it should not be Moriarty who caused Zhou Yi's death in the end.

Su Yun walked towards the bottom of the stairs step by step, and just when he was halfway there, Zhou Yi's voice came from behind him:

"Ouch, Brother Su Yun, come on, come on, do you want to settle a hexagram with me!"

Su Yun looked back and saw Zhou Yi walking towards him on the stairs, Su Yun sighed helplessly, it seemed that it was impossible to completely not interfere with the development of the original events.
