Chu Yuchen stared at the glass door with his eyes, and took out an hourglass commonly used by psychiatrists in his pocket.

2 minutes later, the hourglass had been leaked, and Yan Shiyu didn't dare to breathe during the whole process, staring closely at the glass door for fear of something unusual.

As if realizing something, "This door... Is there a reverse mirror behind it?"

Chu Yuchen heard Yan Shiyu's suspicion, his black eyes stared at the door, and he suddenly realized something!

“... No, run!"

"Ah——!h

She couldn't help but scream in fright, and the reverse mirror shattered in response, revealing a black, shaky shadow hiding behind the glass door.

Only a strange voice was heard, a hoarse and terrible voice, a strange Uru sound came from the throat, and the sharp knife in his hand flashed an extremely bright light under the refraction of the glass door.

"He's got a knife in his hand!"

She was out of breath when she spoke, and her injured feet hurt unbearably, but now she didn't dare to stop at all, and there were heavy panting and footsteps on both sides of her ears.

"Go to the elevator!" Chu Yuchen shouted, turning back violently and finding that the location of the elevator seemed to have run over!

The man behind him was extremely fast, and his well-trained figure was as fast as lightning, holding a knife and rushing towards Yan Shiyu, who had slowed down a step, seeing that the knife was about to fall.

Yan Shiyu used all her strength to push Chu Yuchen forward, and she quickly squatted, dodged the sharp knife, and turned around and ran in the opposite direction.

This mutation made the dark shadow man stunned for a moment, and he sneered lowly, and the voice of the blade swished by, "Where to escape!"

The man's voice behind him was gloomy and chilling, his frightened eyes constricted, and his tense facial muscles twitched slightly.

Chu Yuchen was caught off guard by the words, and fell directly from the middle of the stairs by stepping on the air, only to hear the sound of a heavy object falling on the iron handrail, echoing throughout the high-rise,

"Shi Yu..."The weak male voice looked upstairs in pain, Chu Yuchen fell down a full 4 floors! The fracture of his left wrist was extremely serious, if he hadn't reacted quickly and held it up, I'm afraid it would have been now...

The situation is not optimistic, the red blood slowly flows down the handle, the whole head is blurred with flesh and blood, it looks miserable, and the voice of the shouting is mixed with pain and despair...

No one chased after him, the man who couldn't see his face clearly was chasing Yan Shiwei, and the other party's target was not him...!

When she said that, her face was stained with soil, and she only knew that she was running wildly, and her cold sweat soaked her entire back, and her face was red, which was caused by excessive physical exertion.

Where's the elevator?

Yan Shiyu's lips had been bitten, she staggered and almost fell, and quickly reacted to prop up the ground with her hands and continued to run forward, and the man behind her came with a cursing voice.

"Don't run, you can't run away!"

Yan Shiyu covered her mouth tightly to prevent her panting voice from being heard, and at the same time, under the overload of physical overdraft, she turned left with the last willpower and the brain that had no time to react!

The sound of heavy breathing was suppressed under the control of Yan Shiyu, and the nerves that almost collapsed had reached the limit, and he poked the button of the elevator with his hand, and the elevator showed that the button was up.

Open the door!

Yan Shiyu looked at the black shadow that was getting closer and closer to her in horror, cold sweat flowed down, and her heart was pounding.

Don't! Open the door! Hurry up and hurry up!

The speed of the elevator door is like a year.

Open the door!!

As she spoke, she gasped for breath, and the black shadow saw the pale prey standing at a hot distance, and a wicked and terrifying smile appeared at the corner of her mouth.

"Hey, hey!"

Striding over, the face of the black shadow gradually became clear, and Yan Shi looked at Yan Hao in disbelief, his eyes were like ashes.

Yan Hao saw that Yan Shiyu was motionless, thinking that this woman finally understood current affairs.

Whatever you run, you just lie quietly on the operating table, waiting for the organs to be taken.

It must be wonderful to make such a beautiful face into a work of art!

Yan Shiyu lowered her head and couldn't see her face clearly, Yan Hao laughed arrogantly, "You are finally...!"

The voice stopped abruptly, and the woman in front of her suddenly flashed into the elevator, and the elevator door was slowly closing...

Yan Hao shouted violently and quickly ran over to open the closing elevator door.

The needle in his right hand containing a milky yellow liquid was squeezed hard because of anger, causing a few drops to flow out.

Yan Shiyu trembled all over, wanting to scream in horror, but found that she couldn't make any sound, and her fingers trembled and pressed the door button frantically, almost smashing the door button!

Crying breathlessly, biting his bloodless lips, the fear in his eyes almost overflowing.

Shut it up! Please, close it! She must not fall into his hands!

In the pupils, a pair of copper-colored big hands stretched out like demons, less than a meter away from Yan Shiyu!

"Ahh

Yan Shiyu screamed and jumped up and stepped back, crying tears blurred, "Don't come here!"

The elevator "dropped", slowly walked up, Yan Hao's face like a grim reaper looked at the elevator climbing up, turned his head and went straight to the safety staircase.

How many floors should the elevator stop at?The limit of the human body running upstairs is four floors, and then the speed of running the stairs will be reduced to varying degrees...

But her room is on the fourth floor!

As she spoke, she trembled her hands, and her left hand held the disobedient right hand to press the 8th floor.

The elevator slowly stopped on the 8th floor, and on the safety staircase on the other side, Yan Hao stood between the 4th floors and searched.

Didn't you come to the fourth floor?

Yan Hao chuckled in his heart, and turned his head to the elevator, the elevator showed the location of the 16th floor, and the 16th floor was his room!

Do you think that the most dangerous place is the safest place?

Yan Hao sneered and walked into the elevator and slowly went up to the 16th floor, while Yan Shiyu on the other side hid in the safety staircase, quietly holding her breath, and the elevator showed up!

But is he not in the elevator! Or is he also using a trick to get off the elevator early and press on other floors?

Yan Shi is crazy to calculate all the possibilities, the brain cells have been running to the extreme, no, he must be in the elevator, but when he reaches the 16th floor, he will find that there is no one on the 16th floor!

How many layers will he go to at this time? Yan Shiyu's mind was like a hemp rope wrapped around her nerves, like an invisible net constantly tightening, and she couldn't breathe...

Empathy! Yes, she must think about where she would go if she was the other party, and she would find out that she had been deceived!

After a normal person knows that there is no one on the 16th floor, their first reaction can know that she has done a simple trick, and one trick can't deceive people twice!

Then he couldn't be sure if she would return to the 4th floor he had just searched, or if she was hiding an entire floor in the elevator!

In the case of uncertainty, the safest way is to guard the elevator door! Let the elevator door be kept at the top of the position, so that the speed of the elevator is very slow, a time is wasted when it is opened and closed, it is set on the highest floor, and the elevator will be wasted!

Now there is only a safe staircase left, she is now on the 8th floor, Yanhao is on the 16th floor, she must go down to find Chu Yuchen to meet!

The 4th floor is the dangerous floor, and the 1st floor is the easiest to find, so the 8th floor where she is currently located is the safest!
