Due to the special relationship between Chen Ziyang and Yang Lei's identities, these two people have become the two most idle people in the entire team. Except for the two of them, the rest of the team was busy with their duties, but only the two of them lay down in the canvas gap of the carriage every day and looked out.

On the first day of excavation, all personnel of the entire fleet were assigned tasks. Instructor Liu has a very strong ability to co-ordinate, and also has a certain leadership ability, under his arrangement, the excavation work of the entire team is carried out in an orderly manner.

However, due to the various arrangements and the time it took to install the equipment, the first day of excavation did not achieve any real results. The two large excavators only dug up the surface of the desert.

Although the excavation did not make any substantial progress, Chen Ziyang found that Instructor Liu was in a particularly good mood that day, he kept walking around the entire large excavation site, pointing at this place, and explaining a few words to that place, but no matter where Instructor Liu went, he had a smile on his face, not a long dead donkey face that saw himself and Yang Lei.

The next day, the overall situation was still about the same. Two large crawler excavators have dug very deep, Chen Ziyang visually inspected, these two excavation equipment, each dug a deep pit of several thousand square meters, and the depth of this pit is almost seven or eight meters. However, a depth of seven or eight meters is only a drop in the bucket in the desert.

Although Chen Ziyang didn't know how deep the ruins of this ancient country were buried, Chen Ziyang made a rough judgment by relying on the barely useful word tricks here. Using the surrounding tall sand dunes as a reference, Chen Ziyang estimates that if there are large areas of buildings buried beneath the desert, they will be buried at least forty or fifty meters below the surface of the sand.

But all this is just Chen Ziyang's approximate speculation, because the usefulness of Wenzijue in the desert is very small, the wind and sand in the desert change very quickly, and at the same time, the sand and gravel in the desert all look the same, and it is impossible to distinguish the age of these sand and gravel from the sand and gravel, so the role of Wenzijue is greatly limited here.

Although Chen Ziyang saw that there was still no progress in the excavation work of the team, he saw that Instructor Liu was still in such a good mood today, and even he and Yoshioka Yu found a shady place, and the two of them actually sat there and tasted tea with portable tea sets.

Seeing Instructor Liu's confident appearance, Chen Ziyang pursed his lips, he felt that Instructor Liu was a little careless this time. From the excavation of the entire team, Chen Ziyang roughly judged that it is very likely that the place where Instructor Liu is digging is fundamentally wrong, and there should be no ruins of the ancient kingdom below.

The reason why Chen Ziyang can be so sure is that his judgment is based on those groups of people who use Luoyang shovels. When visiting the tomb in the villa before, Chen Ziyang used the Luoyang shovel for the first time. It is precisely because of the use of the Luoyang shovel that he has raised his understanding of the Luoyang shovel from the theoretical level to a higher level.

Chen Ziyang has a strength, that is, he has a special mind, and he can draw inferences from one another, in the words of the old way, that is, he does not follow the routine. Don't look at Chen Ziyang, he only used the Luoyang shovel once, but this time he summed up a lot of experience. After using this time, Chen Ziyang can be said to have a very good understanding of the Luoyang shovel.

While watching, Chen Ziyang kept staring at those who used the Luoyang shovel. Instructor Liu divided into several groups, ranging from 3 to 5 people in each group, and these people were all holding Luoyang shovels in use, but none of these people gained anything.

And Chen Ziyang also noticed the style of the Luoyang shovel they used. Although the Luoyang shovels they use are not as exquisite as the ones they custom-made, they have all the functions they should have.

And Chen Ziyang noticed that the Luoyang shovel used by these people was also combined, but the one they used was much rougher, and each combined steel pipe was about three or four meters long.

This is located in the desert, the sand in the desert is very soft, and the gap between the sand particles is very large, so it is very labor-saving to use the Luoyang shovel to shovel here.

Chen Ziyang saw that these people had already laid a lot of shovels around the two excavators, each shovel was 30 to 40 meters deep, although occasionally a few shovels were relatively deep, but these people's shovels never brought out anything.

The sand grains in the desert are relatively loose, and it is difficult for the Luoyang shovel to bring the sand out of the desert, because when the shovel is lifted up, most of the sand particles flow down the hollow place in the middle of the shovel, so basically how the shovel goes down and how it will come up.

However, there is only one exception, that is, when these shovels hit some dense hard objects, such as clay pots, or wooden boards and the like, if the Luoyang shovel passes through this kind of thing, when the shovel is lifted up, these things will be stuck in the middle of the Luoyang shovel, and they will be brought out together.

But after watching for nearly two days, Chen Ziyang found that none of these people who went to Luoyang to shovel found nothing. Even if the ruins of this ancient city are buried fifty meters below the ground, what is this place? This is the desert. It takes time for the desert to cover the ancient city, and it takes the movement of the sand little by little.

When the sand slowly covers the ancient city, some of the lighter and smaller items in the ancient city will slowly move under the drive of the wind and sand. In other words, if the ancient city is buried 50 meters below the ground, then within the range of 30 to 50 meters below the ground, there should be many small objects left in the ancient city.

The smaller and lighter the object, the closer these items will be to the surface of the desert, which is very dry and the sand is also isolated from the air, which means that these small objects buried under the sand should be very well preserved and will not rot easily.

However, in the past two days, these groups of people using Luoyang shovels did not even bring a single thing, that is, there was nothing but sand in the sand layer 30 to 40 meters below the surface. Through this, Chen Ziyang is almost 100% sure that there are no ruins of the ancient city below here.

Originally, Chen Ziyang wanted to tell Instructor Liu and Yoshioka Xiong about this situation, after all, the blood-colored diamond had told him that he could heal his sucked left arm in the ruins of this ancient city, and from this point of view, Chen Ziyang didn't want Instructor Liu and them to return in vain. If they miss the month when the diamond key is opened because they are digging in the wrong place, then their left arm will be completely useless.

But after seeing Instructor Liu's arrogant appearance, Chen Ziyang knew that even if he told him now, he would only get merciless ridicule and abuse. Instructor Liu's temperament Chen Ziyang has already figured it out, and he will always do what he recognizes to the end, without hitting the south wall and not looking back, this kid is a master who is dead to the tip of the horns. With this in mind, Chen Ziyang decided to wait a few days.

On the morning of the third day, the first thing Chen Ziyang did when he woke up was to get out of the carriage and look towards the place where the two excavation equipment were located. Now the two excavation equipment are basically invisible, and only the tail of the equipment can be seen at the edge of the deep pit dug by the two equipment, and the pit has been dug relatively deep.

Shovels after shovels of sand were continuously transported out of the pit by these two machines. Chen Ziyang combined the inclination angle of the current equipment and the length of the equipment in his previous memory, and roughly calculated that these equipment had been dug to a depth of more than 40 meters below the surface.

At this time, Chen Ziyang also saw that Instructor Liu was no longer as comfortable as he was two days ago. With a straight face, he walked around the edge of a huge pit dug by an excavation machine with his hands behind his back. Yoshioka, on the other hand, looked down carefully from the edge of another pit. Although Chen Ziyang couldn't see Yoshioka's face now, he judged from Yoshioka's movements that this kid must also be anxious.

The impatience shown by Instructor Liu and Yu Yoshioka let Chen Ziyang know that the two of them also realized that something was wrong, but it was still not time to talk to the two of them about these things. So Chen Ziyang was patient and continued to exercise in the carriage.

In the past three days, because the convoy no longer continued to drive, there was no bumps on the road, Chen Ziyang actually felt that his injuries had recovered very quickly, and his physical strength had also recovered a lot. After all, more than ten days have passed since the injury, and normally the wound should have healed long ago, but the bumps along the way have slowed down the healing speed of Chen Ziyang's wound.

In the past three days, Chen Ziyang felt that the wound on his chest had been a little itchy from time to time, which was a sign that the wound was about to heal, and after these few days of continuous rest, he felt that he was no longer dizzy, and it seemed that the essence blood sucked by the blood-colored diamond had basically been replenished. In addition, Chen Ziyang has now adapted to his dry left arm, so in his spare time, Chen Ziyang has begun to do simple restorative fitness.

On the morning of the fourth day, Chen Ziyang found that the positions of the two excavators had all changed, and they had moved to a certain distance from the previous excavation site. Such a large piece of equipment was moved so far, it seems that in the middle of the night last year, Instructor Liu and Yoshioka Xiong had already given the order, and these two people should have also noticed that something was wrong.

One of the most deadly aspects of digging in the desert is that the soft sand around it will flow down to the deep trenches that have been dug out. Therefore, if you want to dig deeper in the desert, you must use an inverted cone excavation, and the closer you are to the surface, the larger the area you need to excavate.

Moreover, the whole excavation surface is not vertical, but slowly extends downward at a certain angle, so that the sand and gravel on the excavation surface will not flow to the bottom. However, there is also a very big drawback in this way, that is, it invisibly increases a lot of engineering volume.

If you want to dig into a circle with a diameter of 10 meters, it is likely that you will have to dig a circle with a diameter of 100 meters at the point where the conical type touches the ground. Because of this, the two excavation equipment dug a deep pit of several thousand square meters, but in fact, when the pit extends to a distance of more than 40 meters below the surface, the excavated area is not very large.

Seeing that the two excavation equipment did not dig anything at all, Instructor Liu was a little anxious, so he ordered the two excavation equipment to move a large piece to the side, and then continued to dig along the edge of the deep pit dug out of the original, so that only a small amount of work can be used to increase the excavation area of more than 40 meters below the surface.

Chen Ziyang judged that the reason why Instructor Liu did this was because he still felt that his excavation location was not wrong, but because the error was too large, and the area excavated more than 40 meters below the surface was very small, so that he did not see the ruins of the ancient city.

Thinking of this, Chen Ziyang knew that his opportunity was about to come, but today was still not the time, only when Instructor Liu expanded the area of the pit and found that there was still nothing below the pit, he was able to realize that this time it was a complete mistake, and he was able to listen to his own words.

However, Chen Ziyang is also a little strange, it stands to reason that this Instructor Liu should not make such a mistake, he should have done it strictly in accordance with the mantra of finding the ancient country, plus he has the ability to watch stars, these are added together, so Instructor Liu will have that confident expression on his face a few days ago.

But a person who is so skillful and has mastered the mantra of finding the ancient country is wrong, where is this mistake? Is it because it is too wrong to judge the position of the ancient country through stargazing? Or did Instructor Liu misunderstand one of the sentences in the mantra? Or is it not deep enough to excavate the ruins of this ancient country at a depth of several hundred meters below the surface?

Originally, Chen Ziyang wanted to take advantage of the fact that Instructor Liu dug up the wrong place to extract that mantra from Instructor Liu's mouth, but now he is a little hesitant, a smart person like Instructor Liu, who has mastered this mantra for more than ten years, he may make mistakes, even if he knows these mantras, what is the use?

Chen Ziyang doesn't think that he is smarter than Instructor Liu, and at the same time, he doesn't feel that he has the kind of perseverance of Instructor Liu, and now his only advantage is that the blood-colored diamond key in the ancient country was opened by himself, but this Instructor Liu still didn't let himself open the key again when the excavation was fruitless, it seems that there are still many hidden secrets that he doesn't know.

"Tomorrow, I'm going to have a good talk with him tomorrow, or it's probably too late." Chen Ziyang thought in his heart.
