In the darkness, Qian Qian and Yue Yue shouted in unison, and Qian Qian said loudly: "Why is this light extinguished?" The tomb was filled with the sound of water jets crashing down, mixed with the sound of footsteps, Yue Yue opened his mouth and said, "Qianqian, come to me!" ”

I don't believe it's a coincidence, maybe that person, just somewhere watching us at a loss, couldn't help but feel a chill, and said: "You all come to me, this sarcophagus is still some height, with the current speed and density of the water column, I'm afraid that in less than thirty minutes, the water surface will not pass the ding!" ”

"Will the water rise?" Sissi was very surprised: "Won't it flow out through the gap?" ”

Me: ".................."

Yue Yue couldn't help but laugh and said, "If there is a gap for the water to flow out, then wouldn't it be in vain to set up this kind of mechanism in this tomb?" ”

Sissi was suddenly a little panicked and said, "What should I do then?" ”

As she spoke, she came to my side and grabbed my arm tightly, and I felt her trembling body and knew that she was already afraid.

If she could see and touch the enemy poorly, she would not be afraid of anything...... But she is full of brute strength, but in the current situation, it is useless, how can she not be afraid?

Yue Yue sighed: "This water has not passed us, it will take at least one or two hours, and in these two hours, we can slowly find a way to escape." ”

Sissi interjected hurriedly: "Do you have a way?" ”

Yue Yue paused, but did not answer her words, only said: "What I am most worried about now is the problem of oxygen, this tomb is sealed. In other words, all the oxygen is that, how long can the three of us survive? ”

I said, "Don't worry about this for now!" ”

Yue Yue asked, "Why aren't you worried?" Without oxygen, if you don't wait to be drowned, you will suffocate to death, how can you get out? ”

Feeling that the water on the ground had soaked into the shoes, we hurriedly climbed up the sarcophagus and sat on the coffin lid, and I explained to Yue Yue: "Two days ago, the company just reported a problem with ambient air quality. I found all the specific information. I almost vomit every day, so I haven't forgotten this data until now, even though this oxygen is not enough for the three of us for a long time. But at least we don't have to worry about suffocating before drowning! ”

"Oh?" Yue Yue seemed to have slight doubts. After all...... This burial chamber does not seem to be a big deal. There are no more than ten masters, and it is really hard to believe that such a cramped space is really hard to believe. Three people were able to survive in it for a long time.

The jet of water splashed all over us, and I wiped it all over my face, shivering suddenly, Nima was so cold...... He said to them: "The composition of the air is 78% nitrogen, 21% oxygen, and 0% noble gas by volume. 94%, carbon dioxide 0. 03%, 0% for other impurities and gases. 03%。 ”

Yue Yue: "............"

Sissi: "............"

Listening to me recite such a piece of data, the two of them were instantly messy, and they didn't speak for a long time, I felt that something was wrong, and said: "I did too much to report two days ago, and I really overreflexed, sorry, sorry!" ”

Yue Yue said: "To get to the point, in such a big place, can we really use oxygen?" ”

Sissi said, "Luo Xue can still lie to you?" ”

"It's not that I don't believe her, it's just ...... In the end, there is no data to make people feel reassured! Yue Yue was a little helpless, and said: "If something goes wrong, it will be a big matter of life!" ”

What else did Qian Qian want to say, but I quickly intercepted it: "Yue Yue's worries are not unreasonable, if it were me, I wouldn't easily believe other people's empty words!" ”

Sissi muttered, "You're no one else......"

Yue Yuedang didn't hear it, and so did I, so I only said: "According to the data just now, the conclusion is that in the volume of air, nitrogen is about four-fifths, and oxygen is about one-fifth. And according to the literature, an adult inhales 0 per day. 8 kilograms of oxygen, which is six taels of ............ per catty"

Sissi exclaimed: "Can oxygen still be calculated in catties?" ”

Me: "............" rolled his eyes at her, knowing that she couldn't see it, and then continued: "And the density of each cubic meter of air, that is, the weight, is 1. 293 kg is 2. 586 pounds. Then oxygen occupies a fifth of it, which is ............"

"Let me do the math!" I was stuck, so many decimal places, I couldn't do mental arithmetic, I squatted on the coffin lid, and counted on the coffin lid in the dark, Yue Yue and Qian Qian looked at each other, and I didn't know what to say for a while, I didn't know the psychological activities of the two of them, and finally calculated the result, so I looked up and said excitedly: "It's 0." 2586, which is 2. 586 taels! ”

"Huh...... Heh......" Yue Yue laughed dryly twice and said, "So what about ......"

"One cubic meter of oxygen is 2. 586 taels, then ten cubic is ...... Two pounds, five twos, eight ......" I paused: "Oh yes, maybe there are not ten cubes here, so it will be counted as nine cubes...... That is...... You wait for me to calculate......" I lowered my head and was about to calculate again, Yue Yue and Qianqian said in unison, "No!! ”

Ha, it scared me a lot, I looked up at them subconsciously, but I couldn't see my five fingers, Yue Yue coughed dryly, and said, "Don't be so troublesome, just count it according to ten cubic meters!" ”

"Well, the weight of ten cubic meters of oxygen is two catties, five taels, eight dollars and six ......."

"Do you want to be accurate to the money?" Sissi wanted to laugh and cry at the same time.

Although I knew that she couldn't see it, I couldn't help but glared in the direction where Sissi was, and then continued: "The amount of oxygen has been calculated, the three of us, even if each person inhales eight taels a day, the three of us are only two catties and four taels a day!" ”

"Hehe............" Yue Yue was speechless, and could only laugh dryly...... Sissi said: "I'm not worried about being suffocated now, but this water ............"

I couldn't help but spread my hands and said, "Don't count on me about this, there has been no report on this in the society recently, so ...... I can't figure it out either! ”

Yue Yue said: "No, no, this water can be seen...... Well, what you can touch is not the same as oxygen, and you can judge one with the naked eye, which is about the same! ”

"Oops!" Sissi said: "What's the use of just thinking about this? It's good to have that brain to think about how to get out! ”

Speaking of this, I was angry, slapped the back of her hand, and retracted her hand as if she was electrocuted, and before she could shout aggrievedly, I said angrily: "You still have the face to say? If you weren't cheap, would you have been able to get to this point now? ”

Sissi was very aggrieved and said, "Where can I be blamed for this?" ”

"...... you say?" I was so angry that I wanted to beat people again, but then Yue Yue hurriedly came up to play the round and said, "Anyway, the thing is there, even if Sissi doesn't touch it, we have to touch it............" (To be continued.) )
