Yu Xiao felt a chill at first, then thought of something and asked, "Are you sure there is only one old lady in the room?"

"I think so..." Zhou Xiaozhen said puzzledly, "The old lady rushed towards me at that time, and I didn't see clearly."

Zhao Lan asked, "Xiaoxiao, why do you ask that?" "

If, I mean if." Yu Xiao looked into the eyes of the two people, "If our previous speculation is correct, then the bedroom where the old lady is is the future of the bedroom we are in now. But there is only one old lady in that bedroom, which means that we must have successfully left this copy later."

"Yes." Zhou Xiaozhen nodded, "Why didn't I think of it?"

"It may not be this reason." Zhao Lan waved her hand and said, "It is also possible that something happened to us later that prompted us to leave this bedroom. It is also possible..."

She seemed to be reluctant to continue speaking, Zhou Xiaozhen hated it most when she was left half-sentenced. "It is also possible what?"

Zhao Lan showed a painful look. "It is also possible... that old lady is one of the three of us."

Zhou Xiaozhen was dumbfounded. She stammered for a long time, "How is it possible... the three of us are together, if... what about the other two?"

Zhao Lan took a deep breath and said, "Maybe they died in an accident, or maybe... you still remember what Haikuan Tiankong said, the negative energy in the copy will corrode the living. It is also possible that we stayed here too long..."

She couldn't say the rest of the words. The color on Zhou Xiaozhen's face faded, and she looked at her two sisters in a daze.

"Don't make blind guesses." Yu Xiao put his hands on the shoulders of the two, pinched them gently, and said: "I believe that the old lady will not be one of the three of us. Let's not consider the issue of food. You should know that among the three of us, only my points can support me to become an old lady. The points of the two of you are not enough to live to that age."

Zhou Xiaozhen asked seriously: "Then Sister Xiao, how do you know that the old lady is not you?"

"Because I can't live here for so long." Yu Xiao said as a matter of course: "If you all die, then I can't live either. Even if I don't commit suicide, I will go to St. Elizabeth's to be the dean. How can I stay here and become an old lady?"

... What he said made so much sense that Zhou Xiaozhen and Zhao Lan were immediately convinced.

Zhao Lan held up two fingers and said, "Then there are only two possibilities now. One is that we have successfully left the copy, and the other is that we have all left this bedroom."

"These are just our guesses." Yu Xiao tried to show a high-spirited state and said, "Now what we have to do is to verify our guesses."

Zhou Xiaozhen: "How to verify?"

Yu Xiao looked around and said, "From now on, every time we open a space, we will leave some marks in that space that will remain even after many years. If we find marks in the space again, it means that what has changed outside is not only the space, but also the time."

"Okay." Zhou Xiaozhen did what she said, and said, "Let's make marks now."

Zhao Lan said, "Think carefully about the location of the mark, it will be bad if it is destroyed by other patients."

"This kind of location is not easy to find." Yu Xiao said, "In order to leave the copy, the patients should not miss any place in the space."

Zhou Xiaozhen: "Then make a mark that they cannot destroy."

"What mark cannot be destroyed?" Yu Xiao was confused for a while, and suddenly she thought of it, "I know."

Zhao Lan: "What?"

"Why must it be indestructible? Isn't it enough as long as we can make sure they can't destroy it?" Yu Xiao explained: "Let's find a hidden place, behind the bed, behind the cabinet, and write down our identity, our guess about the copy, and the reason for making the mark. I believe that as long as the patient is clear-minded, he should not destroy our mark."

"Yes." Zhou Xiaozhen nodded repeatedly, "Let's do it this way. Where should we put the mark?"

Zhao Lan looked around and pointed at the closet and said, "Let's carve it on the wall behind the closet."

"Okay." Yu Xiao nodded and went to move the closet with Zhao Lan. As soon as they moved the closet away and looked at the wall, their eyes froze.

Because Zhou Xiaozhen had to check the door, she couldn't leave the bedroom and couldn't see what was on the wall. She only saw Sister Lan and Sister Xiao standing there in a daze after moving the closet away, their eyes staring, as if they had seen a ghost, no, it was scarier than seeing a ghost.

"What's wrong?" Zhou Xiaozhen said in surprise, "What did you see?"

Yu Xiao and Zhao Lan looked at each other and swallowed their saliva. They walked to the wall together. On the wall in front of them, someone had carved a line of words with great effort, and you could see the cement inside.

[Our guess was correct.]

Yu Xiao raised his hand to scratch his head. Zhao Lan bit his lip and asked, "Who do you think wrote this line of words?" Yu

Xiao looked at the words suspiciously. Although she found it unbelievable, a voice in her heart told her that the words were written by her. She wrote them by herself. She had a bad habit of writing. The reverse dog radical looked like three circles connected together. And the words on the wall looked like this.

"I..."

Zhao Lan: "What? What do you want to say?"

"I." Yu Xiao couldn't imagine what her expression was at the moment. She said, "This line of words seems to be written by me."

So Zhao Lan also remained silent, and only Zhou Xiaozhen was anxious outside the door.

"That is to say... Although we don't know when and under what circumstances we wrote this, our guess is right." Zhao Lan looked at Yu Xiao, "right?"

Yu Xiao nodded with difficulty.

"Then..." Zhao Lan turned around impatiently, she felt helpless, "Then what should we do next?"

Yu Xiao glanced at the words on the wall again, "Time... I should have thought of it earlier. The attending doctor and the hospital are both named Shi Guang, which means this copy must be related to time. I should have thought of it earlier..."

The two returned to their bedroom, Zhao Lan explained the situation, and Zhou Xiaozhen was shocked.

The three of them sat on the bed with their backs to each other, and Yu Xiao said, "The condition for leaving must be related to time."

"Why?" Zhao Lan asked.

Yu Xiao scratched her head again. Her hairstyle was already very ugly. She said, "The time in the copy is chaotic. We can go to the past or to the future. Suppose, suppose we find such an exit, who can guarantee that after we go out, the time period we are in is the same as our original time period?"

Zhao Lan slapped the bed, "You mean the correct time!"

Zhou Xiaozhen's scalp tingled, "What is the correct time?"

"Our time." Zhao Lan was a little excited. She raised her hand and pointed to the bedroom where they were, and said, "This is our time. From the time we opened the door and came in, the flow of time in this bedroom is the same as ours. If we want to go out, we must find our time, then open the door and go back to the time period outside that belongs to us."

Zhou Xiaozhen seemed to understand, "Then how do we find our time?"

Yu Xiao thought for a while and asked, "Do you remember the time we came in?"

"You mean to open the door at the same time tomorrow?" Zhao Lan immediately took out her cell phone to check. She shook her head and said, "I only know it should be between 8:20 and 8:35, but I don't know the exact time."

Yu Xiao didn't know either. She didn't even notice looking at her cell phone when she entered the room.

"How about giving it a try?" Zhao Lan said, "Starting from 8:20, keep opening the door?"

There was no better way now, so this was an idea. Yu Xiao nodded and said

, "Let's do it this way." Zhou Xiaozhen couldn't think of a better way, so of course she would do whatever the two sisters did. But she still asked, "Should we continue to open the door?"

This was indeed a problem. Yu Xiao fell on her back on the bed, feeling very tired.

"Take a break." Zhao Lan's head was buzzing with various news and speculations, and she also wanted to lie down and rest.

Zhou Xiaozhen felt okay, she was not tired, and she couldn't play with her phone here. So she said: "You guys take a break, I'll go open the door, and call you if something happens."

"Okay." Yu Xiao closed his eyes.

Zhao Lan turned over, and the two of them lay on the bed with their eyes closed to rest.

Zhou Xiaozhen walked to the door and opened it. In fact, she decided to continue opening the door not only because she was bored and had nothing to do, but also because she wanted to find the kitchen. Even if their guesses and actions were completely correct, they would not be able to leave the dungeon until tomorrow morning. Sister Lan and Sister Xiao were so tired that they needed to eat something to replenish their energy.

When they opened the door, there was a toilet outside. It was an old-fashioned squat toilet, very dirty. Zhou Xiaozhen closed her eyes and closed the door.

When she opened the door again, she saw an old-fashioned living room outside. It was very dark and she couldn't see what was inside, but it smelled bad.

Zhou Xiaozhen prayed in her heart that it would definitely be the kitchen next time, and it would definitely be the kitchen next time...

She didn't know if she was lucky or if God really heard her prayers, but the next time she opened the door, it was actually the kitchen. But the situation in the kitchen could not be described with just one word: miserable. In the old-fashioned kitchen, the entire wall was smashed to pieces, and there were clothes on the floor, as well as dark brown traces that were not sure if they were bloodstains. The smell was extremely bad. Zhou Xiaozhen took a look and closed the door in despair.

It was really a torture. With helplessness, she opened the door again.

This time, after she opened the door, she felt a flash before her eyes, and something hit her face.

Zhou Xiaozhen didn't even have time to take out the talisman. She only had time to shout for help before she was thrown to the ground.

Yu Xiao and Zhao Lan on the bed jumped up immediately, and saw Zhou Xiaozhen being thrown to the ground by a gray figure. Yu Xiao kicked it, but failed to kick the figure away.

"Ah!!!" Zhou Xiaozhen began to scream, "It bit me!!"

Zhao Lan immediately took out two chapters of the Thunder Strike Talisman, and two lightning bolts appeared out of thin air and struck down fiercely. The bedroom was filled with smoke, and Yu Xiao covered his mouth and nose and walked over to pull Zhou Xiaozhen.

"Are you okay?" Yu Xiao pulled Zhou Xiaozhen out, "Where did you bite?"

Zhou Xiaozhen didn't say anything, Yu Xiao could only hear her sobbing.

"Cough cough cough...

A cough sounded in the smoke, and Yu Xiao's body tensed up, it was a man's cough.

"Sister Lan!" Yu Xiao shouted, "Be careful! There may be another ghost!"

Zhao Lan, who couldn't see anything, immediately grabbed the talisman with both hands and squinted her eyes to look carefully in the smoke.

"It's not a ghost!" A pleasant male voice said, "I am a human, and I am also a patient."

...

Zhou Xiaozhen was bitten on the back of her shoulder and her neck was nearly broken. Fortunately, Yu Xiao's healing talismans were enough, and after using a few more of them, her injuries were completely healed.

The smoke in the bedroom had dissipated, and on the other side of the door was a very simple bedroom. The room was simply decorated, and there was not even a floor, just cement. There was a wooden bed in the room, covered with printed There was a quilt with red double happiness patterns.

Behind the door of the room stood a person, a man. A

very young man, in his early twenties. He wore a military green shirt and had very fair skin. He was tall and thin, with a good-looking face, his eyes were not pure black, but had a hint of amber, and his temperament was very gentle.

He stood outside the door, watching Yu Xiao treating Zhou Xiaozhen, smiled and said, "You have a lot of talismans."

Yu Xiao let go of Zhou Xiaozhen, glanced at the gray figure lying on the ground and still smoking, and said, "What's going on?"

The man raised his legs to walk in, and Yu Xiao stopped him immediately, "Wait a minute, don't come in."

The man took a step back with understanding, pointed at the ghosts on the ground, and said, "You are the patients who entered the copy several times before, right? I just entered the dungeon and was looking for clues when this thing crawled out from under the bed. I was fighting it when the door suddenly opened, and then you all knew it."

Zhao Lan was surprised to hear him say, "You just entered the dungeon? Is this your first space?"

The man frowned, obviously not quite understanding what Zhao Lan meant specifically, but he understood the general meaning, so he nodded.

"You are so lucky." Zhou Xiaozhen said, "If you met us, you might be able to leave here alive."

"Is this dungeon dangerous? "The man was not nervous at all, and his attitude could be described as indifferent. It seemed that no matter how dangerous this copy was, he would not care. Do you know how to get out?

They were talking, and Yu Xiao was watching from the side. Somehow, she felt that this man was somewhat familiar, as if she had seen him somewhere.

Zhao Lan explained: "We have verified that this copy is related to time. Once you leave the space you are in at the beginning, you will be trapped in another time, or perhaps you will never be able to leave..."

"You..." Yu Xiao suddenly asked: "What's your name?"

The man was stunned, and Yu Xiao said: "I am a patient of the Sixth Hospital. My name is Yu Xiao. What's your name?"

"Sixth Hospital?" The man narrowed his eyes, his eyes confused, "Where is the Sixth Hospital? Isn't there only one hospital? My name is Teng Jingzhi. "

Yu Xiao's breathing stagnated and his eyes trembled.

Zhao Lan and Zhou Xiaozhen also looked at each other in shock, "Are you Teng Jingzhi?"

Teng Jingzhi was puzzled by the reactions of the three people, "Do you know me?"

"You..." Yu Xiao: "Are you Teng Jingzhi from City X?"

Now it was Teng Jingzhi's turn to change his expression, "Do you really know me? Do we know each other in real life? You... Excuse me, I didn't... didn't recognize you."

Yu Xiao blinked and asked, "You... Have you already written that suicide note in your phone?"

Teng Jingzhi was stunned again, "How did you know..."

"Oh my God." Zhou Xiaozhen held her head with both hands, "We actually saw Teng Jingzhi alive, is there such a thing?"
