Hahaha, the man's proud laughter sounded again in the air. Silly children, I have modified the manual control switch. Only the control switch on my side can turn on the fire nozzle. You think too much!

Behind him, countless zombies have become angry and crowded into a group because of the attack. Those who have been knocked down struggle to get up, crowd among the corpses and rush towards Hao Zhi again!

No switch, no spray device, and it's easier said than done to go back to the glass house again.

The voice echoing in the hall showed incomparable arrogance and pride: goodbye, children, you did well, but you were a little unlucky!

"Hum! Don't be so proud!" Hao Zhi smiled contemptuously and raised the art knife in his hand.

You think I took this knife for self mutilation?

oh

The man's voice showed great interest.

This empty room can contain more than just your spray.

what?

This time even Wang Yanke was surprised, but he saw that Hao Zhi was in no hurry. He turned and left the fire box and ran to the elevator door. By the door, there was the body of the soldier!

Wang Yanke suddenly realized that not long after the soldier died, the blood on his body had not solidified!

"Hehe, boy, you have a good idea, but you also have to have that courage... Normal people are afraid of corpses, especially if you have to dissect a corpse with a knife, which requires long-term psychological preparation to overcome!"

Hao Zhi rushed over and held the knife high above his head. The sharp and thin blade flashed cold. It was facing the exposed neck of the dead soldier. As long as he rowed down, the blood would spill out, and the three people would be saved!

But the fact is as Lin Tao said. After all, it's a person. Even if he dies, he has to cruelly destroy the body twice. Normal people will instinctively think of pain, pain and death... It's no better than breaking the packaging box of an express package. After all, people's psychology has an endurance limit.

"Hao Zhi, close your eyes!" Wang Yanke shouted in the glass room.

When Hao Zhi looked back, the corpses had gathered around him. The blood on his hands was still flowing. He had no time to think about it!

Fear finally defeated morality. He suddenly raised his knife, stabbed it without hesitation, pulled it horizontally, and the soldier's neat uniform was cut open. The blood was blurred under his clothes, and the blood quickly flowed under him.

A knife, a knife, another knife... Like a farmer planting rice seedlings, Hao Zhi straddled the dead man, bent down and rowed desperately

Song Xiaojia looked at Hao Zhi's desperate action and couldn't help whispering: "I made a song. He won't kill us, too?"

The corpses suddenly smelled the greater smell of blood splashed out, and they all rushed here frantically. Hao Zhi took off his vest, wrapped the wound on his arm, quickly avoided the wall, and ran around to the glass room.

The zombies, like ants meeting a big piece of sugar, crazily licked around the dead soldier's body. Hao Zhishun road opened several dead bodies. He had already escaped safely to the door of the glass room. Song Xiaojia opened the door, and the two girls rushed out and hugged Hao Zhi excitedly.

"Ha ha, I didn't expect this. You're not stupid at all!" Song Xiaojia patted Hao Zhi on the shoulder excitedly.

"Hurry up, we have to hurry upstairs!" Hao Zhi turned and took the lead, ran towards the ladder entrance and got into the dark corridor

There was a faint warning light above the emergency exit, shining on the dim yellow in the stairwell, narrow and humid, with a rotten smell.

Three people rushed into the entrance of the ladder, turned back and closed the wooden door opposite the entrance of the ladder. The world was quiet in an instant.

Just a moment of panic and fear, the clothes of the three people had been soaked with sweat. In this way, it seemed that the stairs were gloomy, cold and empty.

Looking up, the staircase in this staircase is not the staircase style of ordinary civil buildings, but a cylindrical patio. In the middle of the patio is a spiral upward iron staircase, steep and cold, like a huge DNA double helix structure model made of metal.

Song Xiaojia takes the lead. After Hao Zhi breaks, he climbs up the stairs one after another. After climbing for a long time, he turns dizzy and swollen. Song Xiaojia finally sits on the steps. If he doesn't climb, he has to rest for a while. If he turns again, I'll throw up!

Wang Yanke squatted down, took Hao Zhi's art knife, bared and cut a long piece of cloth from his trouser leg: "come on, I'll help you wrap up your arm, and you'll die if you lose blood!"

Hao Zhi happily stretched out his arm with full warmth. Wang Yanke carefully put his arm on his leg, and then wrapped it tightly with cloth strips in circles.

She tooted her small mouth and complained in a low voice: "you are really cruel to yourself. You pull it down after making a cut. It's so hurt that I can only help you delay the bleeding temporarily. I'm afraid it won't work if you don't sew..."

Feeling Wang Yanke's concern, Hao Zhi became happy. It was worth another two knives to get the gentle girl's care.

Song Xiaojia sat on the high steps, looked at the picture of two people warm bandaging their wounds, snorted with disdain and turned her head.

Hao Zhi roughly estimated that the three people have walked for 15 minutes since they stepped up the stairs. No matter how slow they climb, they should reach the top!

"But it's the height of the 18th floor. Why haven't we reached the roof yet?" Hao Zhi muttered strangely.

"Maybe it's fast. Let's go. We have to hurry. There's only one hour. I don't know if the grandson will break his promise!" Song Xiaojia reluctantly stood up and continued to take the lead to climb up.

After walking for more than ten minutes, the three finally sat down panting again. They were too tired. Climbing stairs was the most physical activity.

"The situation... No, it's not right..." Wang Yanke gasped and wiped his sweat. "The stairs... How do you seem to go? You can't get to the end?"

Infinite loop?

Song Xiaojia jumped up. Is it the "panlos ladder"?

"I saw it in the book ghost blows the lamp. It's also called the hanging soul ladder. No matter how you go, you can't get to the end!"

"Impossible!" Wang Yanke made a firm judgment. It's OK in fantasy novels, but it's impossible to make it in the world we live in, unless

Unless what? Hao Zhi doesn't like reading and is confused.

Unless we are in a four-dimensional space, that kind of stairs can't really appear!

"I have to praise you again, miss. Your judgment is as good as your knowledge!" the man's voice appeared again. The three people looked up instinctively, but there was still no one.

"This is my personal little invention. Its name is' only half of the stairs up ', that is to say, if it is not for identity verification, you are only allowed to walk half of the stairs. You can never walk up the other half. Of course, it is impossible to leave. Even if you want to go downstairs, you can never finish it. No matter how you walk, you can only stay at this height!"

"Impossible! How can there be such a thing in this world? Will the stairs automatically lengthen as we climb up? Even if it can grow, it can't grow into space?" Song Xiaojia retorted loudly.

If you don't believe it, you can try it! Ha ha ha

By the way, you have less than half an hour left! But during this period, we can play a game. You can get five minutes extra time for each question you answer.

"Go home and ask your mother!" Song Xiaojia angrily gestured a middle finger in the air.

"Don't... we are in other people's game now, so we can only act according to the rules formulated by the other party. Don't be impulsive. Maybe it's a delaying measure..." Wang Yanke whispered together with Hao Zhi and song Xiaojia to analyze, and then said loudly to the invisible voice in the air, "ask!"

"That strange girl with curly hair, I want to know, when did you find your strength different from ordinary people?"

I? Song Xiaojia didn't understand why the other party suddenly became interested in him, so he scratched his head: "Probably after I went to junior high school, I gradually had this strength. At first, I was no different from ordinary girls, but later, my strength became stronger and stronger. Hao Zhi wouldn't let me tell others that scientists would take me away for dissection and make specimens, so outsiders didn't know at all. Even my parents didn't say..."

"Is there a similar situation among your parents and family?"

"No... I may be the only one!" Song Xiaojia shrugged and smiled.

"Do you know they adopted you?" the voice suddenly inferred.

Song Xiaojia jumped up: "you are adopted. Your father, your mother, your sister and your whole family are adopted!"

"Don't be unhappy. I'm just guessing this possibility. After all, you are different from most people. You remind me of a good friend many years ago..."

"Will people like you still have good friends? Hum!" Song Xiaojia fought back discontentedly.

Just when song Xiaojia quarreled with the mysterious man, Wang Yanke on one side always frowned and his brain kept running fast. What's the matter with this damn staircase?

"Let's go. We can't talk to him here. He's trying to delay our time. We have to hurry up and open the elevator door to save Lele and Dian!" Hao Zhi clapped his hands and stood up and encouraged the two girls to say, "climb another stage. Ke Ke Ke also said that the stairs that guy said can't be true. As long as we insist, we can always climb to the end!"

Wang Yanke hesitated to look up and down the stairs and shook his head, but he didn't say anything. He had to run up with Hao Zhi. The three climbed quickly for a while and stopped panting again

In the dark corridor, the three people looked at each other. Hao Zhi lay down outside the handrail of the stair railing and looked up and down. It seemed that both ends of the huge stair were still extending, and there was no end at all!

They were still in the middle of the stairs, and the strange situation showed their mysterious face again.

"It's over, we'll never get out of here!" Song Xiaojia almost sat on the ground and cried. Hao Zhi expressed understanding and sighed. He felt extremely tired all over. The sense of despair that can never see the end was collapsing. Even he almost had the idea of giving up.

"Don't be discouraged, calm down and don't be deceived by the other party!" Wang Yanke wiped the sweat on his face, threw it aside, and then said to Hao Zhi and song Xiaojia, "there's only one way left now!"

What can I do? Hao Zhi looked helplessly at Wang Yanke's bright eyes in the dark, as if they were shining with excitement.

"You two stand still!" Wang Yanke told her, then turned around and walked downstairs tentatively.

"What are you doing? There are zombies down there!" Hao Zhi shouted.

Wang Yanke ignored him, went down several steps and turned around the stairs several times. From the height, there was a drop of three or four meters from the two people, and then stretched out his head and shouted up, Hao Zhi!

Um! Hao Zhi lay on the handrail of the stairs and looked down, but in the dark environment, Wang Yanke could not be seen at this distance.

"I just threw my sweat on the wall. There should be water marks on the wall. Look, is there any more?" Wang Yanke asked loudly.

sweat stain? Watermark?

Hao Zhi felt out his mobile phone, turned on his flashlight, and squinted hard at the cylindrical wall under the strong light. The patio of the ladder was very narrow, and the wall was within reach of the stairs.

The wall is dry and there is no watermark!

"Nothing!" Hao Zhi replied loudly.

Wang Yanke nodded. At this time, she was staring at the wall corresponding to the position she was standing on. On the wall, there were clearly a few watermarks, bleeding out deep colors

She smiled
