Looking at these strange plants, Instructor Liu seemed to suddenly remember something, and then he asked everyone to follow him and follow the root system of these plants. However, Instructor Liu's order made Chen Ziyang feel a little puzzled.

If Instructor Liu's order was to let everyone follow him to the depths of this space as soon as possible, it would be understandable, after all, Chen Ziyang knew that among all the people, he was the only one who was most anxious about this ancient treasure. But Instructor Liu asked everyone to follow him and follow the roots of these plants, which made people feel strange.

After thinking about it carefully, when Chen Ziyang saw these plants for the first time, Instructor Liu did not give such an order, and everyone thought that these plants were just some vines, but these things were relatively hard and different from ordinary plants.

However, when everyone noticed that these plants had become thicker for the second time, and thus deduced that these were not vine plants, but seemed to be the root system of some kind of plant, Instructor Liu's attitude changed.

Carefully thinking about the changes in Instructor Liu's attitude before and after, Chen Ziyang came to a conclusion, it was very likely that the treasure of this ancient country that Instructor Liu had been looking for was related to a certain plant, so when he knew that these plants climbing on the side wall of the space were the root system of a certain plant, he gave such a strange order.

For a long time, Chen Ziyang couldn't figure out what kind of treasure could make someone like Instructor Liu so obsessed. From his previous words, he judged that these treasures were definitely not some property, but for Instructor Liu, he had taken off everything that existed, otherwise, he would not have endured it for more than ten years.

Chen Ziyang has been pulling Yang Lei to walk at the end of the team, although it is said that Instructor Liu's weapons are on the two of them, but after all, the two of them lack experience in fighting, especially now Chen Ziyang is half disabled, and if he really wants to fight, he can't use his strength at all. Be careful to sail the ship of ten thousand years, it is better to watch out for these people.

The secret room of this ancient country is not too wide, the distance between the left and right is not very far, but it is very long, under the illumination of the flashlight beam, the place where everyone can see is full of these strange loess coffins. Some of the loess coffins have been damaged, but without exception, there is a skeleton in these loess coffins.

After a rough calculation in his heart, Chen Ziyang has seen no less than four or five hundred of this kind of loess coffins seen by several people so far.

Four or five hundred coffins is just a number, but when Chen Ziyang really saw more than five hundred loess tombs, this visual impact was very shocking, and wherever he could see, there was nothing else except this loess coffin.

"I said Eryang, you said that the people of this ancient country are really poor enough, we have seen so many graves, and there are many damaged ones, and there is not even a single burial item in it, how did they live.

Isn't this closer to the Hotan area, I was still wondering if I could get him a piece or two of Hetian jade, a small fortune, if I could touch a Hetian Ziyu, it would be perfect. Yang Lei looked east and west while saying to Chen Ziyang.

"I think you're crazy about money, it's okay to want money, but you have to have some knowledge about money. It is true that it is relatively close to Hetian, but the mining history of Hetian jade is only more than 1ooo.

What is this place? The ruins of the ancient kingdom of Sumi, the ancient kingdom of Sumi existed in the Western Han Dynasty, more than 2,000 years ago, and it is very likely that Hetian jade had not been seen at that time. ”

"Hey, it's a pity, maybe this trip will be in vain again. It's not strange that you say that this surname is Liu, it took more than ten years of hard work, just to find some plants, it seems that this kid should not be short of money, unlike us, he has not lived a hard life. Hearing that it was likely that Hetian Yu could not be found here, Yang Lei was a little depressed.

"Don't look around, focus on the two people in front of you, be careful to let these two people overshadow us, after all, things have come to this point, it is still more beneficial to the two of us, maybe you can get out alive, no matter how much treasure you find is the saddest thing."

Knowing that there was probably no treasure to be found here, and that everything looked exactly the same, Yang Lei lost interest in these loess coffins. But Chen Ziyang is different, in the process of moving forward, he has been paying attention to observing the bones inside the loess coffin.

All of these bones are relatively intact, and it seems that the people who died here should not have died of external injuries, although occasionally there are a few bones with broken or broken bones, but from the healing of the bones, it can be seen that the injuries on those bones should have been formed many years before the death of this person, and they were not their fatal cause of death at all.

Instructor Liu opened the way in front, but his eyes were not at these loess coffins, but at the plants on the side walls of the entire space, and as everyone advanced, the roots of these plants climbing on the walls seemed to be thicker.

Although Instructor Liu had been paying attention to these plants, after walking for a while, he realized that something was wrong with the situation around him, so he made a gesture and signaled everyone to stop, and everyone looked at the environment left and right, and they also saw the difference here.

Not far in front of everyone, one by one loess coffins disappeared, replaced by loess mounds, and a clear dividing line was formed between the loess coffins and the loess mounds.

Because such a strange thing happened suddenly, Instructor Liu didn't dare to act rashly. He turned his head and looked at Chen Ziyang with an inquiring gaze. Looking at the loess mounds on the ground, Chen Ziyang was also a little puzzled.

Walking in front of Yang Lei, Instructor Liu stretched out his hand, wanting to borrow a sapper shovel from Yang Lei to dig up these loess mounds and see what was inside. But his request was denied.

"Don't, let's do this kind of work by ourselves, your old man is expensive, and he can't use this strength, not to mention that I'm afraid that you will use this shovel to split my head in half at once." While teasing Instructor Liu, Yang Lei walked to the nearest loess mound, and began to dig the loess with a sapper shovel.

The loess mound is not too large, but the shape of the entire loess mound is very similar to the previous loess coffin, and it is also an oval hemispherical shape. Looking at this familiar style, before Yang Lei completely dug up the loess mound, Chen Ziyang had already roughly guessed what was underneath the loess mound.

Sure enough, after a few shovels went down, Yang Lei dug up the loess on the loess mound, and a corpse buried in the loess was exposed.

"His grandmother's, I thought there was something valuable buried here, it turned out to be a poor dead man." Seeing this corpse, Yang Lei seemed to regret the strength that he had wasted just now.

Seeing that there were still only human bones under the loess, Instructor Liu lost interest again and continued to walk forward. Chen Ziyang, who was at the back of the line, was thinking, why didn't the people here use brass coffins? Is it because of their humble status? It doesn't make sense at all. And judging from the linen cloth worn by the corpse just now, his identity should be the same as the person buried in the loess coffin before.

Generally speaking, the people buried in the innermost part of the tomb are the most noble, while the people buried in the outermost part are the lowest. It doesn't make sense that the person buried at the entrance used a loess coffin, but the person inside only buried the bones with loess, which is unreasonable. But Chen Ziyang couldn't figure out the reason, he always felt that something was wrong here.

The rest of the way was accompanied by the five people all this loess mound. These loess mounds are arranged in exactly the same style as the previous loess coffins, one after the other, leaving a small gap between them. And as everyone marched, the roots of the plants climbing on the wall became thicker and thicker, and now they were the thickness of human arms.

After walking for a while, the five people felt tired, and when they stopped to rest, Chen Ziyang estimated that not counting the hundreds of loess coffins before, there were already more than 1ooo of these people buried under the loess mound alone.

And along the way, the scale of the loess mound is getting smaller and smaller, and the loess used is getting less and less, and even several corpses are exposed outside the loess.

"You said that these ancients also did some tofu scum projects, and those who died before also used a loess coffin to do some superficial work, so that people who entered here thought that it was all this kind of loess coffin.

But then it's over, it's buried with loess, and it seems that these people are still cutting corners, and the loess is being used less and less. Yang Lei said while eating, looking at the surrounding loess mounds.

Although Yang Lei was half-jokingly talking about these things, his words were heard by Chen Ziyang.

"Something is wrong, it's not that these people from the ancient kingdom are cutting corners, it's not that they're getting lazy, it's ......"

Thinking carefully about all the clues, when Chen Ziyang remembered the soul of the little girl who was counting, and the pattern that the little girl carved on the wall, he suddenly came to his senses.

"Quick! Put on your gas masks! All the people here are dying of the plague! He hurriedly reminded the four people around him. Then Chen Zi Yang Xun put his hand into the backpack, but after touching it for a while, he suddenly realized that there was no gas mask in his backpack at all.

Before going down to the deep well where the stone platform and stone pillars were located, in order to reduce the size of his backpack, Chen Ziyang threw some equipment that he felt unusable in the car, and did not wear a gas mask at all.

Hearing Chen Ziyang's shout, the other four people were all startled, and even Yang Lei was frightened, a biscuit that he held in his mouth choked directly in his throat, and coughed for a long time before he spit out the biscuit.

When Yang Lei was coughing, Instructor Liu asked Chen Ziyang, "Why are you so sure that these people died of the plague?" We didn't even have gas masks on us, and we didn't know where we got it by the sand. If these people really died of the plague, chances are we've all been infected. ”

After sighing, Chen Ziyang shook his head helplessly, because of Yang Lei's reminder, he strung all the clues.

From the previous clues, it can be inferred that within a certain period of time, the people of this ancient country continued to die, and this period lasted for more than three months, which is why the little girl painted more than 1oo villains lying on stretchers on the wall.

At the beginning, the little girl still wrote a number next to each villain, but in the later stage, these numbers disappeared, only the pattern of the villain remained, Chen Ziyang estimated that it was because in the following time, too many people died in one day, and the little girl was too much to count.

In other words, the number of people dying every day in this ancient country is increasing, and in addition to the cause of war, the only thing left is that it may be disease, and only infectious diseases such as plague can make so many people die one after another in a period of time.

The death toll from the plague will increase over time. Because when more and more people get sick, the degree of infection will also become faster and faster, which is why the later it is, the more people die in a day.

In addition to these clues, Chen Ziyang's basis is another one, that is, these loess coffins and loess mounds.

In the early stage of the plague outbreak, the number of people who died in one day was not too many, so these people were buried well, and a loess coffin was built outside the bones, in addition to burying the dead, this loess coffin is likely to have another use, that is, to prevent the leakage of the virus, but it is unknown whether people in that era understood the virus.

But in the later period, the number of dead people increased, and the loess coffins could no longer be done, so the people who buried these dead simply buried these people with loess.

Even in the later stages of the plague, it may be because the loess has run out, or it may be because there are fewer and fewer people burying these dead, so the further you go inside, the more rudimentary these so-called coffins become.

After thinking through all this, Chen Ziyang Yue affirmed his thoughts. Seeing that all five of them did not have gas masks, and that after walking for so long in this cemetery where the plague dead were buried without protection, he felt that none of them could escape the fate of contracting the plague virus.

"You don't have to worry too much, even if these people really die of the plague, the probability of us contracting it is very low." The team doctor, who had been silent along the way, spoke rarely.
