In the classification of the Seven Divisions of Maoshan, Chen Ziyang felt that the most difficult thing to learn was the knowledge of the Maoshan Star Division. Lao Dao once left a lot of Maoshan classics, these books covered a part of the knowledge of the various classifications of the Seven Divisions of Maoshan, and Chen Ziyang read almost all of these books.

Although he has only read many things in the book once, and he is not proficient in it, he can also know a general idea. However, it only involved a booklet of Maoshan Star Master, and Chen Ziyang only read the beginning and gave up.

The words in the book are obscure and at the same time very profound. Originally, Chen Ziyang still wanted to study carefully, but when his current Maoshan Star Master's book was only compiled by Maoshan descendants themselves according to the beginning of a fragment, and it was the most elementary of all the Star Master classics, Chen Ziyang gave up completely. This job of Maoshan Star Master is not something that anyone can do, at least he thinks he will never be able to do it.

So at this time, when Chen Ziyang saw Instructor Liu standing in the distance measuring the position and angle of the stars with a sextant, and pinching his fingers to calculate something, Chen Ziyang knew that this Instructor Liu still had the ability to watch stars, but he didn't know what his level was.

The method of Guan Xing is all-encompassing and ever-changing. One of the most basic uses of stargazing is to determine the position of the mark through the position and angle of the stars, which is somewhat similar to the dragon hunt in Feng Shui, except that the dragon hunting trick is based on the location of the mountains and rivers, plus the twenty-four mountains to record the geographical location, while stargazing uses the position and angle of the stars.

The ancients have long found that the same star is in different positions in the sky in different seasons. Therefore, it is more difficult to simply use stars to mark the location of a certain place, and the angle of the stars must be added. Therefore, it is only the most elementary application of stargazing, and it also requires stargazers to be familiar with the trajectory of the stars in different seasons.

Originally, Chen Ziyang wanted to secretly tell Yang Lei and let him find a way to get close to Instructor Liu and Yoshioka Xiong, and eavesdrop on what they were talking about now, and it was best to get the mantra they knew about the treasures of the ancient country, but after carefully looking at the terrain where Instructor Liu was located, Chen Ziyang dispelled this idea.

Probably to prevent others from eavesdropping, the relatively high sand dunes chosen by Instructor Liu and Ji Gangxiong were very far away from the convoy, and only the car they drove in the entire small area, and the others were very far away.

And the surroundings of the two of them are very empty, there is no shelter at all, under the bright moonlight, the scenery around the two of them can be seen at a glance, so Yang Lei has no way to sneak close.

Looking up at the twinkling stars in the sky, Chen Ziyang now except for the Orion constellation and the Big Dipper, he doesn't know any of the other stars and constellations, and Orion is still because the three stars on Orion's waist are very obvious, so he can remember it.

Looking at the starry sky, Chen Ziyang was intoxicated. Nowadays, the air pollution in the city is very high, and the various lights that flicker at night make the stars that are already hidden by the sand and dust even more inconspicuous, so it is difficult to see the night sky in the city.

At this time, in this desert without pollution and without the influence of light sources, the stars in the sky look very bright and clear, the whole night sky seems to have just been washed with water, and the stars in the night sky look very numerous, very dense.

At this time, this beautiful scenery looks very peaceful, and there is a refreshing feeling that comes out of nowhere for some reason, which is very comfortable and very happy to watch.

However, looking at the dazzling stars in the sky, Chen Ziyang thought of another thing, although he didn't like Instructor Liu very much, and was even very hostile to him, but now Chen Ziyang actually admired Instructor Liu a little.

This person has been able to endure for fifteen years, just for the goal of the treasure of the ancient country, so many years of not giving up so single-minded, this person has such energy, his attitude can do things well no matter which side he puts on, what people are most afraid of is serious, Chen Ziyang has now regarded Instructor Liu as the most terrible opponent in his heart.

Thinking in his heart about the mantra that can manipulate blood-colored diamonds, Chen Ziyang kept staring at Yoshioka Xiong and Instructor Liu after seeing enough of the starry sky. It was at this time that he saw a scene that was difficult for him to understand.

At this time, Instructor Liu was facing away from Chen Ziyang, his hands were pinched around his waist, his shoulders were bent together, as if he was saying something excitedly, and Yoshioka Xiong, who was standing next to Instructor Liu, looked at Instructor Liu's respectful face, and nodded from time to time, as if he recognized Instructor Liu's reprimand.

At this moment, Chen Ziyang was a little confused. How did the identities of these two people seem to be reversed? Ji Gangxiong should be Instructor Liu's superior, and when the two of them appeared at the same time, Instructor Liu was also respectful to Yoshioka Xiong. All the orders were also given by Yoshioka Yu, and Instructor Liu was just like a small leader.

But at this time, how to look at the scene in front of Chen Ziyang's eyes, how is it not like this, because Yoshioka Xiong is far away from the two of them, and the reason why the light is not too good at night, so Chen Ziyang feels that it is likely that he has misunderstood too subjectively, these two people are just talking normally, and they have misunderstood.

After calculating at the stars for more than an hour, Ji Gangxiong and Instructor Liu drove back to the convoy, and then the entire convoy went out again, and this time the convoy traveled very fast, it seemed that Instructor Liu had determined the location of the ancient ruins through the stars.

However, objects that can be used to determine the location of the stars are generally relatively large objects, ranging from villages and towns, avenues, mountains, rivers and valleys. Therefore, there is a big disadvantage of using astrological signs to determine the position of objects, that is, the error is very large. Even for an object as large as the ruins of an ancient country, it is very difficult to determine the location of 100% of the time using astrology.

So on the way, under the command of Instructor Liu, the convoy stopped three times, and Instructor Liu also went to a high place to observe three times, and after many times of position correction, at dawn, Instructor Liu led the convoy to a location.

It looks like a basin in the middle of the desert, except that the basin is not surrounded by mountains, and the ground is not sunken. There are some tall sand dunes in the distance. These dunes act as a natural wind barrier, and such tall dunes move very slowly, even in the face of strong winds.

It is precisely because of the presence of these sand dunes that it is not buried by the sand blown by the strong winds. Although he didn't know what was going on, looking at the tall sand dunes in the distance, Chen Ziyang felt that there was probably something underneath those dunes, otherwise, these sand dunes would not be so tall, much taller than the large sand dunes he had seen along the way. It is precisely because of this that Chen Ziyang feels that Instructor Liu should have found the right place.

Under the command of Instructor Liu and Yu Yoshioka, the people in the convoy were divided into two parts. Some of them were installing the large excavation equipment under the command of Instructor Liu. They unloaded the equipment from the car and began to build, while Yoshio led the rest of the people to set up a temporary base for long-term habitation.

The construction of the base was simple, and Yoshioka gathered all the vehicles that were not used together and formed a large circle. Then dig out the sand in the middle of the circle so that the circle around which the car surrounds creates a sheltered depression. Not only can you sleep here, but you can also stock up on some important supplies in case they are blown away by the wind and sand.

The camp under Yoshioka's command was quickly completed, but it was not so smooth with Instructor Liu, the two large excavation equipment were very difficult to assemble, and the equipment was also very large, and it was not until the evening that Instructor Liu arranged for someone to assemble it.

Looking at these two behemoths, Chen Ziyang and Yang Lei glanced at each other, and they both saw a trace of shock in each other's eyes. It's too big! These two excavators are just too big! Before seeing these two pieces of equipment, Chen Ziyang and Yang Lei didn't know that there was such excavation equipment in the world, and they didn't even dare to think about it.

Crawler chain bucket excavator, this is the name that Yang Lei himself gave to this kind of equipment. Both machines are identical, looking like a long tank track. It's just that this track is much longer than the tank track, and if the ring of the track is opened, the length of this track is likely to reach 1oo meters long.

On this track, at intervals, a large shovel head similar to an excavator's bucket is attached to it. The tracks and all the shovel heads are connected to the levers that are directly connected to the various machines in and around the middle of the tracks, and the whole two weird excavators are placed diagonally, high on one side and low on the other.

Before Chen Ziyang and Yang Lei could see the overall structure of this strange equipment, the two excavators moved under the command of Instructor Liu. Then the two people saw that with the transmission of the track, the buckets were dug into the sand under the crawler one by one, and then the sand was loaded upside down in the bucket and transported to the rear of the crawler, where the soil was poured into the empty truck under the excavator.

The whole excavation equipment integrates excavation, transportation and unloading. Seeing the power of the excavation equipment, Chen Ziyang figured out why Yoshioka Xiong and Instructor Liu had to bring these two behemoths all the way over. These two excavating equipment are very convenient, very fast, and most importantly, very effective.

Each crawler excavation equipment is equivalent to dozens of excavators working at the same time. Bucket by bucket of sand was dug out in a steady stream. When the sand underneath the excavator has been dug clean, the excavator will easily turn in one direction and continue digging downward.

After carefully staring at the two excavators for a long time, Chen Ziyang and Yang Lei roughly figured out that these two excavation equipment should be specially used for digging in the desert.

Whether it is the style of the excavator or the way it operates, it is very suitable for digging up the sand, and this crawler excavation equipment seems to have been developed for digging in the desert.

After watching these people busy for a day, Chen Ziyang and Yang Lei were a little tired. The two of them had not slept the night before, and this one had been so noisy by the busy people outside that they couldn't sleep at all, and after the excavation work might have been going on for several days, the two decided to sleep first.

The two of them still slept in that compartment, and according to their status, there was no place for them in the center of the camp surrounded by vehicles, and now the truck where the two men slept had become part of the camp. However, what made Chen Ziyang feel comfortable was that the female team doctor who had been following the two people was gone.

After the team doctor left, the reason why Chen Ziyang was so happy was not because he hated this woman, but because he felt that this person was sent by Instructor Liu or Yoshioka Xiong to spy on him.

With this woman here, Chen Ziyang felt awkward, and now that there was finally a space with only him and Yang Lei, Chen Ziyang put his mind down steadily, fell asleep there.

Although there was a lot of noise outside and the sound of machines roaring incessantly, the two people in the carriage slept very well. When the two of them woke up, it was already the morning of the next day, and even the two of them slept so much that they missed breakfast.

Chen Ziyang, who was hungry, looked outside the carriage, and in the entire huge basin, except for two more relatively large sand pits, there was no change at all.

At the same time, Chen Ziyang also showed a disadvantage of this crawler excavator, that is, this equipment can only excavate a large area horizontally, if the longitudinal excavation with depth is adopted, the sand on both sides of the equipment will continue to fall down and pour into the deep pit of excavation. Therefore, this kind of excavation equipment can only dig the surface soil one by one, and when the entire area is dug again, it will be dug again and gradually deepened the depth of the excavation.

Maybe Instructor Liu also showed the disadvantages of this equipment, or maybe he knew before that in addition to the excavation places of these two machines, Instructor Liu also arranged for a lot of people to carry out small-scale excavation in other places. Even Chen Ziyang saw several groups of people using Luoyang shovels to hit the bottom of the sand.

As far as the eye can see, the entire basin is full of people, vehicles and equipment, but after a night of digging, these people have not gained anything at all. Although the area of an ancient country site is not small, it is still pitiful compared to the boundless desert. In particular, the location of the ancient country is still determined by stargazing, and the error is also very large.

All of these elements come together to make excavation of the ruins of the ancient city very difficult. Chen Ziyang knew that it would not happen overnight to dig up the ruins of this ancient city, so he looked down at his left arm and let out a long sigh.
