The Underworld Detective

Five minutes later, we had difficulty breathing, but the rescue was delayed, Huang Xiaotao had fallen to the ground, sweating cold, and gasping desperately: “Song Yang, I may not be able to! ”

I'd like to say don't exhale, but I can't. I'm also seriously hypoxic and drowsy.

The knife god suddenly said: "If one person dies, the others may be saved. ”

As he raised his knife to himself, I yelled, "No! That makes no sense. ”

The knife in his hand suddenly fell to the ground, his right hand trembled constantly, and he, like everyone else, entered a severe oxygen deficiency, in which his hand was as strong as it was white.

I exhausted my last airway: “Don't give up. Even if you are in a hypoxic coma, your body will be able to support you for about five minutes. Uncle Sun must be diligently digging through the passage right now, we still have hope!” In this desperate situation, willpower is important, but I did not tell them one thing: after a long period of severe oxygen deficiency in the brain, the brain dies and becomes a vegetable.

I think hard, there's a way to save everyone. At this time, I heard the ticking water, I stood up, I felt a little light on my head, dark in front of me, so I slowed down, I looked around and found a wall leaking.

As if I saw a glimmer of hope, I waved weakly: "Come here! ”

We almost climbed under that wall, and the explosion could have blown through the inner pipe, and I dipped a little water in my hand, and it was tap water, and I said, "Do something to get more water! ”

Huang Xiaotao asked: “What do you want water for? ”

My voice is getting weaker and weaker: "Hydrogen and oxygen can be electrolyzed in the water to support us for a while. ”

“But where to get electricity, there are lights, but on top of your head. ”

“Your radio battery!” I said.

Everyone's frustration swept away. Officer Liang took off his beret and took off a nylon shirt to cover it. The knife god kept poking the wall with a knife, and the water was increasing.

I took out the lithium battery in the radio, smashed the whole radio, and found two wires in it to connect to the electrode. I just needed a piece of metal to make the electrode. Officer Liang pulled out a packet of cigarettes, and I folded the tin paper inside into a square to serve as the electrode.

I plugged the positive and negative electrodes into the water and waited for a while, some very small bubbles appeared on the electrodes, and Huang Xiaotao's purple face had a smile: “Song Yang, it worked, you are amazing! ”

I laughed sadly: "Just high school physics. ”

The battery's limited power and low amount of oxygen that can be electrolyzed can only alleviate our lack of oxygen.

I've heard the stones moving outside, nobody talking, waiting quietly. At this time, the door was knocked for a while, and the voice of Sun Tiger came, as if it were far apart, and it was very thick.

Sun Tiger roared: “Are you in there? ”

As I watched the battery run out, I walked up to the door and knocked hard, shouting to the outside: "There's not enough oxygen, drill a hole! ”

“What?”

The door was so thick, I shouted Sun Tiger three times before I heard it. I was tired and I had fallen asleep and sat by the door. I noticed that the weird device on the wall was no longer flashing, and the red light was on for a long time, and it looked like it was an oxygen detection device.

One minute later, there was a bombing outside the door, and the SWAT was drilling with a portable electric drill. I was trying to fuel them. Come on!

The sound of the drill bit got closer and closer, suddenly a spark appeared on the door, a hole appeared on it, because the negative low pressure in the house, fresh air poured in, everyone breathed happily, Sun Tiger shouted across the hole: “Are you all right? ”

“It's good!” I nodded: “Do something to open the door. ”

“This door is too thick. We need to blow it up. You guys try to stay away.” Sun Tiger warned carefully.

“Okay!”

When I heard the beep, the five of us looked up together and saw the device on the wall go from a red light to a green light. I had a bad feeling when I paused.

The walls on both sides burst into flames, the bricks collapsed like sugar blocks, and two giant metal plates appeared behind the walls, quickly squeezing towards the middle. I instantly realized that the oxygen detection device was meant to kill us, and that once there was an oxygen influx, it would activate the second option, and the watchmaker's design was painstaking.

Hearing the movement inside, Sun Tiger shouted: “What's going on! ”

I replied: "Uncle Sun, the wall is shrinking. Don't blow it up yet. The watchmaker should be nearby. If you catch him, you can disarm the machine! ”

Sun Tiger replied: "I left some people to continue blasting and the rest to catch people! ”

The metal walls on both sides soon shrunk to a meter wide, and the knife god suddenly ordered a sentence: "Stars, you jump on top and cut the glass with a black knife, maybe you can escape! I'm here for you. ”

Song Xingshen bit his lip and looked at me. I nodded at him, so he quickly climbed onto the wall, supported the wall with his feet, and pulled the knife towards the tempered glass.

The knife god held his hands against the wall, and I heard his joints make unbearable crisps, Yellow Peach biting his teeth: “Together! ”

We held on with our hands so hard, I felt like my hands were crushing and my muscles were breaking. In fact, the strength of only four of us is irresistible. There is also an important reason why the shrinking wall slows down. The ground bricks are piled together, forming a support for the time being.

But the brick structure is fragile, collapsing under enormous pressure, and the space left to us is increasingly limited.

At this time, a broken noise came from above. Everyone looked up with surprise. Song Xingsheng had broken that glass. He threw the knife in his hand, supported the wall with his hands and kicked it with his feet towards the broken glass.

After kicking his four legs, the whole piece of glass cracked open, and he entered immediately and rushed into the control room of the machine.

Song Xingsheng glanced at the board and said: “I don't know what to do! You guys come up first. ”

I said, "No, one man lets go and everybody dies. ”

Song Xingshen bit his teeth: “Young master, I'll let you live! ”

Liang suddenly shouted: "Cut off the power or find a way to shorten the system. ”

Song Xingshen looked around and hit the control board with his fist, pulled two wires out of it, connected the two wires together, immediately burst out a dazzling electric spark, only heard a blow, the organ stopped, the pressure on us suddenly loosened.

I gasped for a long time and felt my hands almost unconscious. Officer Huang Xiaotao and Liang were all sweaty and even the sword gods were gasping.

Sun Tiger knocked hard on the door outside and shouted, “How are you? ”

I said, "Uncle Sun, we don't have to blow it up. We found another escape route. ”

Sun Tiger said over there: "Okay, great! I have some good news for you, too. The watchmaker caught it and killed it, to be exact! ”
