I saw Zhe Xi turn around and leave, so I put on an oxygen mask, took out a flashlight, and walked another road with heavy gas gas.

I was afraid that he would delay there for too long and wait for me to pass, and that something would happen, but fortunately he was not impulsive.

The oxygen mask is tightly covered to prevent some harmful gases from entering. Our oxygen cylinders are not pure oxygen in the traditional sense, which can be poisoned. Under normal circumstances, medical oxygen cylinders are filled with pure oxygen, which is placed next to the nose through the catheter, and most of the oxygen in the catheter is air for each breath; Our oxygen cylinders are ordinary air with high oxygen content, which is very light and easy to carry, and correspondingly small, with not much storage.

After such a toss, the road to Zhe Xi's side has been completely blocked, and the small quicksand in the road of my escape is leaking down one by one, and I can't delay any longer, so I grabbed my belongings and ran.

The road slopes all the way down. I accidentally tripped over a small point of the falling stones, and the big one was in the middle of the road, and my center of gravity stepped forward on the rolling pebbles, and I lost my balance and simply hugged the package and rolled down.

The sand that flowed down gathered on the ground and formed a strong resistance, I didn't dare to stop and get up and continue to move forward, but I was so anxious that I tripped and rolled a few times, and on my back side up, there was just a wisp of falling sand piled up on my chest. The slate suddenly shattered, and stones and sand covered my head.

This time I can't run, I sighed, the area is too big. I could only watch the sand and gravel fall, and although this moment was short, it felt long.

"Boom", ordinary firecrackers are simply inaudible in front of this sound. Even though my head was about to be flattened by the slate, I lifted it up and looked at me, the direction from which the voice came.

The stones fell and collided with each other, creating sparks that exploded through the area where the gas was strong.

The stone that was about to smash my head was suddenly swept away by a wave of air, and I only felt a huge force pushing on my body, and I flew uncontrollably.

I could only protect the vital point, and then I was slammed into the wall, and the oxygen cylinder almost killed me, but fortunately it didn't explode. Try to curl up to reduce the risk of being hit by the rocks set off by the air waves, but fortunately, there is a rope tied to the top of the flashlight so that it is not lost, and I can see the larger stones and dodge in time.

Luckily, there weren't too many rocks flying here. As soon as the idea came to me, I forcibly moved up a few inches, parted my legs, and thrust between my legs with a clang. He took a hard breath, but he was stunned and held back only halfway, moved his upper body a few feet to the left, and quickly sat up. The package smashed on the place where the head had just been, and the mess was scattered all over the ground.

Quickly stood up and looked around, I was already at the bottom of the cave, and the collapse seemed to have stopped, finally good news. I picked up the scattered items, hoping that Zhe Xi was okay.

I had already thrown everything I could throw when I ran for my life. The package was littered with artifacts that should never be thrown away, so I took off my coat and put them inside.

Finally, pull out the path that is inserted into the ground. However, with such a simple movement, I heard the sound of something shattering, and I looked down in disbelief, and the ground I was standing on quickly cracked, and I fell.

It was another steep slope and saw some bright light. I began to roll down, which was dangerous, and my head could easily touch the stones on the ground, so I slammed my path into the nearby wall and clung to the hilt of my sword. The wall was soft, and the full sword sank in with ease, stopping me from rolling down.

The quality of the oxygen cylinders is so good! The mask fell to the side.

"Brother?"

It was Zhe Xi's voice, and I was simply ecstatic, "I'm here." ”

Suddenly, I felt pain everywhere on my body, and I wanted to stand up against the wall but found that it was very slippery, and I fell again. Fortunately, Zhe Xi ran over and helped me up.

I saw in the distance what seemed to be the bottom of the cave.

"Brother, the explosion just now scared me to death, if you die, I will be martyred with you, no, with the funeral. Our brother said okay, he died on the same day and month in the same year," Zhe Xi chattered excitedly, and a stream of water suddenly erupted from the place where the path was inserted into the wall, interrupting his words.

"Isn't it!" I was helpless, the path was sprayed out, I bent down to pick it up, quickly put away the mask to avoid tripping over the catheter, and pulled Zhe Xi across the water and ran up.

"Brother, run down, run down, the top has been completely blocked, and we will be drowned if we run over." Zhe Xi shouted.

Running down is not faster than drowning! This is my subtext, not spoken. Turning around and going down the river, the walls of all the places we passed exploded, and the surging water directly filled the roadway and followed us all the way.

We didn't run far to the bottom of the cave, and it seems that our two brothers are doomed today. I wanted to give Zhe Xi a hug, but he pressed him into the cinders on the ground.

"Brother, lie down, close to the ground, mouth wide open." Zhe Xi shouted.

Trust that goes deep into the bone marrow is that no matter what the other party says, I don't think about it, I just do it.

The wall burst for a while and stopped, but the underground river formed a curtain of water that kept moving forward, threatening to drown us.

Getting closer and closer, I reached out and grabbed Zhe Xi, and suddenly there was a roar in my mind, as if my body had been crushed, and my eyes seemed to be unable to withstand such pressure and wanted to fly out through my eye sockets like bullets.

It took a long time to get used to this feeling, so you shouldn't be dead, right? If you die like this, it is considered a kind of happiness, and there is basically no pain.

When he opened his eyes, Zhe Xi lay on the ground bleeding and smirked at me, "Brother, we're not dead!" Are you okay? His face was covered in blood. ”

I sat up and didn't speak, because I was shocked by what I was seeing. The curtain of water formed by the underground river is not far from us, and no matter how hard we try, we can't move forward even a bit.

Because this is a dead end, the underground river water is impermeable to the bottom of the cave, so the pressure of the air resists the water.

"How did you come up with this idea?!" I couldn't believe we had survived like this, and there was excitement in my voice.

"One of my colleague set the world record for the longest time he was trapped underground, and he was in a similar situation to us." Zhe Xi was also very excited.

"How long has he been trapped?"

"Eight hundred and five hours, that is, thirty-three days and thirteen hours, was found by rescuers."

This is simply a miracle of life, more than a month, even if people are put alone in a place with beautiful scenery and pleasant scenery, let them support themselves, many people will not be able to stand it in less than half a month.

Zhe Xi and I carefully observed the surroundings, there was a distance of about seven or eight meters from the bottom of the cave to the water curtain, the way up had been blocked, and it took about five minutes to swim to the place connected with the underground river.

"Brother, it seems that we have to wait for rescue, you must hold on for thirty-four days and beat his record." Zhe Xi turned off the flashlight to save energy.

I laughed, "Don't get cranky, rest for a while before you go." ”

"Where are you going? They're all trapped here. He got up and walked to the water curtain, took a sip of water, and washed the blood off his face.

I walked over and drank water like this and it was an amazing experience. You need to tilt your head, pout your mouth, suck the water into your mouth, have a sweet taste, wash your face, and feel refreshed. "Have you forgotten what you're carrying on your back?"

Zhe Xi touched the oxygen cylinder with his back and immediately laughed. "Brother, this quality is okay!"

When he was about to set off after resting, Zhe Xi rubbed in every possible way, took off his pants and squatted down at the bottom, leaving some evidence that he had been there.

"Brother, do you have any paper?"

"Let's use panties"

"But how do I take it off when I'm squatting?"

"You won't stand up!"

"But it's uncomfortable to stand up and the middle of the two halves is slimy."

"You can also not wipe it." I smell something.

"Okay, I'll take it off! Brother, I stepped on it! ”
