After the tomb door was opened, a sour smell of decay came out, the smell was really enough, no one had opened it for many years, there should be no vents inside, the air did not flow for a long time, and it was easy for people to suffocate when they entered.

After the ancient tomb, once people rush in, it is easy to suffocate to death, most of the oxygen content in it is very thin, especially the kind of ancient tomb that is very deep underground without a vent, generally after opening the robbery hole, the tomb robber will not enter the same day, will rest for a day, let the air inside circulate naturally, so as not to die unclear.

In addition, because it is buried in the ground all the year round, the corpse inside will inevitably decay, all kinds of gases gather together and can not be dispersed, there will be a series of chemical reactions, comparable to biological weapons, according to legend, Qin Shi Huang's tomb, there is also a kind of vacuum tomb, as long as people go in, the organs inside can immediately pump the air clean, there is no out, like this tomb, in ancient Egypt and the Amazon generation, have been recorded.

In fact, this is all anti-theft measures in the ancient tombs, after all, no one wants to be stolen after their death, the treasures collected during their lifetime are stolen, and they wish to be filled with mercury in their tombs, so generally only the real imperial tombs, do not need this kind of defensive measures, will leave vents in the tomb, this kind of thing is also divided into two sides, after all, some people, do not want to be able to change their breath after death.

Therefore, the general tomb robbers will let the ancient tomb naturally go down the wind before going down to the tomb, and will not be in a hurry, after all, the tomb is there, and will not run away by themselves with long legs.

There is also a direct way after all, that is, to bring a few living creatures, there are a lot of people who raise birds in Panjiayuan, Beijing, and some of the bird raisers, the identity is a little different, when the Tufuzi who is not able to resist the tomb generally, he will tie a goose in front to lead the way, as long as the goose does not die, there will be no danger to life, even if it triggers some mechanism, it can be dealt with in time.

And the more powerful, will be specially trained birds, this kind of bird has a general name, called the tomb spirit bird, which is used to guide the way in the ancient tomb.

There are several well-known varieties of such birds, and they are all quite expensive, but they are really useful, and I am thinking about getting a few over there in the future.

If you want to be simpler, there is also a simple way, go to the vegetable market to buy a pigeon, help with the kite string on the feet, throw it in and let it fly, if you can't die, the tomb can go down, after half an hour to pull the line back, if the line is broken, or the pigeon is dead and the body is divided, you have to think twice about going down to the tomb.

These are the local methods left by the ancestors, and now that science and technology are so developed, many professional tomb robber gangs have begun to use robots and flying cameras, this kind of thing is a bit high-end, but it must be learned in the future.

"I'll try!" The fat man said while taking out a fire fold, opened it and threw it in, the fat man's strength was very great, although the fire fold was light, but it was also brushed out far away, to our surprise, the fire fold had not yet landed, and it was directly extinguished.

"Come on, let's get some sleep, look at this posture, now we are allowed to go in and die one by one, and our gas masks can also cover the smell, and they can't fight the anti-virus effect." The fat man said with some disappointment, but he was quite open-minded, and after finishing speaking, he began to look for a place to lie down and sleep.

I looked at my watch, it was just three o'clock in the morning, and after working for so long, I was really tired enough, it was time to rest.

"Step back a little, the air inside will come out, and it's not safe for us to sleep here." I nodded.

When the fat man heard this, he walked back to the road just now, about fifty meters or so, and I saw that the distance was about the same, so I motioned for the big guy to stop.

Sleeping in the ancient tomb is definitely a very exciting thing, after all, this is a place where the dead sleep, and the living sleep here, I always feel very weird, but now there is no way, the main tomb can not enter for the time being, and I can only sleep first.

The fat man was very sleepy, and I didn't want him to keep vigil, so I motioned to Liang Zi and Trigger to be on the first shift, and I and Biscuit would be on the second shift in three hours, so I would come first tonight.

Liang Zi and the trigger one left and one right, a few of us lay directly on the ground, I and the fat man and Huo Nan's jacket were blocked by the crack of the door, fortunately, Liang Zi's backpack stuffed a marching quilt, directly sideways, the three of them did not dislike, directly squeezed together and began to sleep, the fat man is like a big heater, these gloomy and desolate tombs do not feel cold.

Coupled with the last Warring States Tomb, this is the second time I have gone to the tomb, but it is the first time I have to sleep in the ancient tomb, naturally I can't sleep, I can't sleep when I lie on the cold stone floor, and my head begins to think crankily.

I thought about a lot of things, from the big zongzi in the Warring States Tomb, to Zhang Moxing and the fat man, and Dad, when I thought of Dad, I thought that I didn't seem to have seen him for two years, and I don't know where he is now......

After three hours of confusion and sleep, Liang Zi and the trigger came over and woke me up with the biscuit, I rubbed my eyes and sat up, gave up the position to the trigger, Liang Zi handed me the rifle, sat directly on the ground and squinted his eyes.

Holding this ninety-five, my sleepiness almost disappeared, just like a biscuit to start a vigil.

The number of people who died in this tomb was estimated to be a thousand, if not 10,000, and I leaned against the wall with my gun, and my eyes kept staring at the location of the main tomb, and I always felt as if there was a pair of eyes staring at me all the time, which felt very strange and penetrating.

I took a cigarette out of my pocket and lit it, I looked at the position of the biscuit again, it was very dark, he couldn't see anything on his side, in order not to waste electricity, we all turned off the flashlight, just lit two candles, the biscuit sat quite far away from the candle, I could only see the candle flickering, as if it was going to go out at any moment.

I can't help but think of people lighting lamps and ghosts blowing out lamps, after all, this is in the tomb, dealing with the dead, we lit the candles, if they go out later, no matter what the reason, I feel quite frightened in my heart.

So my eyes focused on the candle in front of me, and after about an hour, just when I had some water to drink, and wanted to drink some water, suddenly a biting cool breeze blew, and I shivered violently, and this cool breeze seemed to be able to penetrate my clothes and blow directly into my body, and I only felt that my scalp was blowing up, and this cold was not the kind of winter cold, but the kind of eerie cold.

Almost at the same time, the candle in front of me ......

Extinguished!
