Although there is a machine in this excavation, it is much slower than expected, every 30 minutes of digging, the hammer has to rest for a while, although the person is not too tired, but the machine needs to be cooled, 4 wolf warrior members took out the sapper shovel to help clean up the excavated soil.

And this excavator is not very advanced, just think about it, Ma San and Iron Hammer are not rich, they have lived very hard before, and there is no such advanced tool as in the movie or novel.

After dark, Liu Jie decided that today's excavation work will end everywhere and continue tomorrow, after all, the sight and danger at night have improved a lot. Although I really want to enter this ancient tomb as soon as possible and deal with that monster, I am not in a hurry to do so.

After finishing work, Ma San and Iron Hammer were also tired for a day, originally Liu Jie wanted to arrange for the Wolf Warrior members to send two people to the hotel at the bottom of the mountain to take a hot bath and rest for a night, but they were rejected by Ma San, Ma San and Iron Hammer just smiled at Liu Jie, saying that the two of them have not suffered a lot, and they have experienced a lot more than this, and now they are doing good deeds, not for money, and the mentality is not the same, if Liu Jie really wants to thank them, just wait for the two to finish the matter, please have a good drink.

Liu Jie nodded, then took the two of them to the tent, briefly ate the food brought by the Wolf Warrior members from the bottom of the mountain, and then arranged for the two of them to live in the tent next to him.

It was another peaceful night, the monster did not appear, early the next morning, Ma San took the hammer to eat some dry food, and then continued to dig, from morning to more than 3 o'clock in the afternoon, with a boom, the hammer shouted excitedly: "Third brother, get through." ”

Then drop the digger, turn around and run. Liu Jie was startled, thinking that something was wrong, and immediately waved his hand, and all the wolf warrior members immediately made an attack state, and Ilya instantly ran to a place where no one was there to transform, holding the ruby magic wand in his hand.

Iron Hammer gasped for breath, Liu Jie hurriedly stepped forward and asked, "Brother Iron Hammer, what did you see?" ”

Iron Hammer gasped and said, "What did I ~ see? I saw that the hole was opened. ”

Liu Jie was stunned for a moment and asked, "You opened the hole, why did you run out in such a panic?" I thought you were attacked by a monster or a zombie? ”

Ma San walked over with a smile and patted Liu Jie's shoulder and said with a smile: "Brother, I think you misunderstood, the reason why the hammer ran out without even taking the tools is for a reason, the ancient tombs are generally less than a hundred years underground, and more than a thousand years old, and there is no oxygen in such ancient tombs, this kind of sealed ancient tombs, there are corpse gas, swamp gas, and many other harmful gases, and the moment you open the channel, the underground gas will gush out along the channel, and if the hammer does not run out in time, most of them will die under those gases." ”

Liu Jie nodded again and again when he heard this: "It turns out that there are still these words, so when can we enter the ancient tomb?" ”

Ma San took a puff of his cigarette and said, "Send your men to guard near the entrance of the cave, and for 72 hours, don't let them get close to the entrance of the cave, and don't inhale any gas floating out of it." ”

When Liu Jie heard this, he immediately asked the wolf warrior members at the entrance of the cave to stay away from the entrance of the cave, and then left these 4 teams to guard here.

Liu Jie turned his head to look at Ma San and asked, "Third brother, your consciousness is 72 hours, can we enter the ancient tomb?" ”

Ma San shook his head and said: "We don't know the structure of this ancient tomb, because I haven't entered it yet, and we don't know if there are vents in this ancient tomb, whether there is poisonous gas in it, so we have to wait for three days to let fresh air enter the ancient tomb, and then we are using some means to check it, and we can enter." ”

Liu Jie nodded and said with a smile: "That's good, just listen to the third brother, we are not bad for these 3 days, we are waiting for 3 days, we are deciding whether to enter the ancient tomb or not." ”

Three days passed in a blink of an eye, on the afternoon of the fourth day, Ma San called Liu Jie, and then took two packages with the hammer, and walked towards the hole entrance, Ma San came to the entrance of the cave, looked inside the hole, and then took out a prop from the package, it should be said that it was a small plate, and then put a candle on it, with hooks on the four sides of the plate, Ma San hung the plate with the candle with a rope, and then took out a lighter, lit the candle, and then put it down towards the hole little by little.

Liu Jie looked at Ma San with a candle and asked curiously, "Third brother, do you want to see if there are ghosts in the ancient tomb?" ”

Ma Sanyi was stunned and said helplessly: "Who did you listen to?" ”

Liu Jie smiled: "Do you want to blow the lamp?" Doesn't it mean that if the candle is extinguished, you can't go to the grave? ”

Ma San shook his head with a wry smile and said, "If candles can detect whether there are ghosts, how many people in this world dare to use candles, and who else dares to open a candle shop?" ”

Liu Jie knocked twice in embarrassment and asked with a smile: "Then third brother, why do you want to put candles in?" ”

Ma San sighed and said, "It seems that you are in school, and your grades may not be good." ”

Liu Jie paused for a moment, thinking about it, if there is no system space, his academic performance is indeed not very good, but with the system space, his brain has become smarter, and his grades have improved.

Ma San continued: "Carbon dioxide is denser than air, and when carbon dioxide is less, it is not harmful to the human body, but when it exceeds a certain amount, it will affect people, and other organisms are also breathing, because the concentration of carbon dioxide in the blood increases, the acidity increases, and acidosis occurs. If the candle is put down and extinguished quickly, it means that there is a lack of oxygen underneath and is not suitable for the grave, and the candle can burn all the time, which means that there is enough oxygen below for us to breathe. ”

Ma San sighed and said: "Brother, it's okay to study more, I know you're busy, but you can't be illiterate, and you still blow out the lamp, I really don't know what you think." ”

Liu Jie shrugged his shoulders with a smile, and then looked at the candle in the cave, the candle kept burning, Liu Jie asked excitedly: "Third brother, the candle is burning, it means that we can go down, right?" ”

Ma San shook his head and said, "Don't worry, let's watch for a while, if this candle is completely burned out, it's not too late for us to go down, it's hard to say now." ”

Liu Jie sighed, and then several people crawled at the entrance of the cave, watching the candle burn, Ma San said with a smile: "In fact, there is another advantage of putting down the candle, that is, you can find out whether there are creatures in the ancient tombs, and some ancient tombs have live mouths, not necessarily where they lead, so there are often some animals in the ancient tombs." Candles can draw them closer. ”
