After Qu You saw the information on the tablet, his eyes once burst into a dazzling light of survival.

However, Qu You only woke up after seeing the 3D schematic diagram later, yes, how could the murderer be kind enough to make such a gamble with him that would let him live.

This is clearly to let himself go to the road of death.

The blood was still slowly flowing down his arm, and Qu You felt that his body was a little cold.

He wouldn't be stupid enough to make a choice easily, and he didn't dare to look at the screen of the tablet in front of him, he felt that watching the time decrease by second was like watching his own death slowly approach.

And below that countdown there is a line that reads, "You're running out of time!" This line of small characters is more like an invisible palm pinching his neck, and the more he looks at it, the more he feels panicked, and his hands and feet are even colder.

He held the only remaining tank of oxygen in his hands, it was his last hope, and he didn't want to suck it into his lungs so easily.

Even in his hands, he felt that he now had the hope of life.

If a person in the dark does not have a time benchmark, even after a long time, he may only feel that a short moment has passed.

When Qu You, who was holding the oxygen tank with his head down, began to gasp for breath, and Qu You, who also had a painful and struggling expression on his face, greedily pressed the respirator of the oxygen tank to his mouth and nose, he finally moved his somewhat wooden expression and glanced at the time on the tablet.

03：30！！！

Qu You shook the oxygen cylinder in his hand, and there was still a small half in it! His face had a complicated expression of triumph, triumph, and bitter helplessness.

He wanted to let go of his wild laughter, this countdown could not decide his life or death at all, even if he didn't choose to gamble, the remaining oxygen in his hand could easily let him survive the three and a half minutes!

The murderer miscalculated! He lost!

Just when Qu You was thinking like this, "Boom! Boom! Boom! Qu You suddenly heard a knock above his head that almost burst his eardrums.

He was stunned for a moment, he hadn't realized what the sound of the knock meant, having been trapped here for a day, meant. But after a pause for a few seconds, a look of ecstasy appeared on his face.

He opened his mouth and wanted to shout for help, but before he could shout a word, he was horrified to find that on the tablet in front of him, the words directly below the countdown suddenly changed, becoming "Bet or die!" The choice is yours! ”

The knocking sound outside seemed to be no longer there at this moment, and Qu Yu looked at the words on the screen in horror, and he realized that the sound of knocking on the 'cellar' might not be the one who came to save him at all! It was the sound of the murderer's urging!

His heart was pounding uncontrollably at this moment, and he felt that the blood flow throughout his body seemed to become extremely fast, and the blood began to slowly seep out of the wounds on his arms that seemed to have scabbed.

His legs also began to feel the sensation of kneeling on the blade of a knife because of the flow of blood.

He wanted to scream in pain, but when he opened his mouth, he found that there was no sound coming from his vocal cords, only a faint "terror" sound coming from his open mouth.

His hands trembled involuntarily from the pain, and he could barely hold the last tank of oxygen he was holding, because he wanted to fall to the ground because of the pain.

Sweat glands play an extraordinarily efficient role at this moment. The pain of Sui Yu, when he couldn't distract himself from the pain with screams, sweat seeped out of his pores, and he who had been hungry for a day seemed to collapse in an instant at this moment.

The precipitation of a large amount of sweat made most of his physical strength consume in an instant.

The oxygen cylinder in his hand slipped limply from his hand and slammed to the ground.

Qu Yu was no longer able to reach out from the iron ring that had entrapped him, and picked up the oxygen cylinder on the ground. He looked pale as the oxygen cylinder on the ground smashed and bounced off the ground, he always felt that it was like he was struggling powerlessly in the hands of the murderer, no matter how much he jumped on the oxygen cylinder, he would still return to the gravitational embrace of the earth, and his life would eventually return to the hands of the murderer.

Qu You could now clearly feel his blood flowing out of his veins and then pouring out of his body from the wounds on his body, which was a sign that his life was quietly passing.

It turned out that the countdown given by the murderer was not a countdown to running out of oxygen at all. He gave a countdown to his death due to blood loss.

Perhaps, perhaps, if you try the method shown in the diagram, you may be able to find someone who can ask for help!?

Qu You looked at the chain that hung his two arms, and then looked down at the ground in front of his knees, although he didn't see it really, he still found the two grooves that seemed to be able to bounce, which should be the cylinder that can pierce his body in the schematic diagram!

When he looked at the groove, Qu You's body shook involuntarily, he didn't have the courage to do that, even if he bled to death, he didn't want to choose the end of being stabbed through the body by two cylinders.

Qu Yu stared at the grooves in the ground in confusion, and he didn't notice that the 'cellar' he was in seemed to be slowly moving upwards.

It wasn't until the whole 'cellar' shook with a bang that he suddenly realized that something was wrong.

He looked up at the time on his tablet, which was now 00:38.

Qu You's lips trembled slightly, and he stepped back.

"Knock Knock Knock !!" He heard a knock overhead again. He didn't think it was the murderer's knocking. But he didn't dare to respond, and he couldn't do it.

He curled up backwards, like a wounded wild dog trying to curl up in the corner of the "cellar".

Even if the people outside were policemen, he didn't want anyone to bother him now.

His eyes widened, staring at the countdown on the screen, decreasing by second.

"Bang dang!" There was a sound from outside like an iron lock hitting something, and he shrank back into the corner again in fright, trying to protect his body with his hands. His eyes scanned the "cellar" in horror, especially the grooves in the ground, and he feared that the cylinders on the ground would suddenly burst out and pierce his body.

“10！”

“9！”

“8！”

......

“2！”

“1！”

In the midst of Qu You's horrified gaze, he finally saw the numbers on the tablet jump to 00:00! There are no sharp cylinders sticking out of the grooves in the floor!!

The horror and fear on his face turned into ecstasy in an instant, like a Sichuan opera changing his face.

It was at this time that he suddenly heard "Bang! There was another loud bang, and it was the sound of the iron lock being broken. Then a voice came in from outside, "Is there anyone inside?" ”
