If you want to conduct a deep scan, it may take a lot of energy or even a lot of time. These are not something that Yang Heng and others can afford.

It is still possible to just scan the surface of the planet and see the changes of the planet. Why do you need to scan it? This is because the legacy left by Emperor Xuanyuan needs to be found with some special landmarks, rather than the coordinates and locations given. This is mainly to prevent the third-type intelligence from being obtained inadvertently, and initially it is necessary to confuse the second-type intelligence.

In the research of type 2 intelligence, people have also been worried about whether this intelligence will generate consciousness. However, no matter how these intelligences generate consciousness, there is no way to judge some special things, such as several markers, plus several special instructions.

The prompt left by Emperor Xuanyuan was a painting, and there was another sentence. One painting was a terrain, and there were no buildings on it, but there were mountains, water, rivers, and trees, sunshine. In a word, there were only four words, the place of death.

How to explain these, Yang Heng, Li Er, and the generals and ministers have conducted many researches, and even asked about the spacecraft system many times, but have not received any effective instructions.

But what is this instruction? There are mountains in the picture. These mountains have four special places, which may be able to deal with the word "death", that is, the four characters. If the death is changed to hope, would it seem more reasonable? So the location of the heritage is determined. However, where is the qualified place? Judging from the planetary pictures released by the system, there are no peaks on this planet, and the only one that has not changed are those rivers. This was confirmed by the system. At that time, Emperor Xuanyuan only leveled some peaks, but for the rivers, it was just reinforced and did not change the way. So, it would be better to find this river, but this river only appeared in one section and had no characteristics. Whether it is a river or multiple rivers, there would be such a section.

So my mind fell into a misunderstanding again, so I came back to observe this painting again. This painting was in spring and at noon. Also, the trees on the edge were very distinctive, the tall ones were very tall, and the short ones were all the seedlings that had just budded. Will there be any prompts here? According to the size of the seedlings, a considerable number of them were of the same height.

So I checked the information again. Through comparison, I knew what trees these were, how tall the tallest ones were, how tall the seedlings just grown, and even what are the differences in different places in the north and south. So, based on the shadow of noon and the leaves of the seedlings, we can judge what dimension this is. Well, this may be a bit exaggerated, but based on the picture of the entire planet in front, we can compare the dimensions of these seedlings in. You must know that this planet is much larger than the earth. These four seasons are more obvious. Perhaps the seedlings cannot explain much, but as big trees, the trees in each dimension are still different.

These are collective thinking. For example, trees, some people have said that we should consider the appearance of trees, pay attention to the impact of seasons on trees, and pay attention to the differences between the same tree between the north and the south. Therefore, when one suggestion is concentrated, the specific dimensions will be roughly judged.

Then, I searched carefully based on the image. Well, another problem arises. I have been missed twice for the image on the surface of the planet, and there is a phenomenon that is easy to ignore. In one place, the playback of these two times will be a bit slow, and no difference can be seen without watching it dozens of times.

Also, in this slow place, the buildings seem to be a little uncoordinated. The corresponding four mountains are four passages, and they are in irregular shapes. This is rare in some square urban construction. Even in the entire image, there is no place similar to this place. If other places have regular shapes, there is irregular shapes here.

After scanning the surface, the longitude and latitude of the planet are generally given. You should know that in a planet covered by smoke and a planet with geomagnetic disorder, the longitude and latitude are difficult to determine. Only by scanning the world and positioning some key buildings. Although the entire planet's surface is ruined, the height and even some outlines of some buildings are still there, especially coastlines, rivers, and lakes, are all the standards for positioning.

"Report to the marshal, determine the location, and whether to go to the target location now." Why can the system confirm now? In fact, it is easy to use an intelligent system to confirm the fixed coordinate points. This is beyond the reach of manpower.

"Locate and perform deep scanning." This time, it is a deep search. Naturally, things like airships cannot be used. As deep scanning instruments, they are a bit too large, and only spacecraft can carry them. They are closely integrated with the system. This instrument is also a unique equipment for this adventure spacecraft. Furthermore, it is a separate equipment on the ground.

"Report to the Marshal, after scanning, I found the underground bunker and the underground entrance. The underground bunker was five thousand meters below the ground, and the entrance was blocked by many big rocks." While the spacecraft reported, the sectional view of the scanning ground was also displayed on the screen. A hundred meters above it was melted, so now, the only way to let the prospecting airship take action.

"Brother, what are we looking for? If there are so many days, can't we go out to play?" Not only the baby, but also the children on the spacecraft were waiting for Yang Heng's reply, because they found that the commander here was Yang Heng, so they naturally had to come to find Yang Heng, while Li Er and the others returned to their cabins to rest. They just came to pay attention to the progress occasionally. In order to give the children a place to play, Yang Heng canceled the screen in the command room except the screen in front of him, and even some seats and the tracks below were covered. This became a cabin for the children to play, and the game rooms in front were now given to the soldiers and some places for them to exercise their physical fitness.

"Be good, go and play with your friends. When the elder brother digs out something, I will call you." The children left disappointed and played those boring games again. It was really boring on the spaceship. If some videos on the spaceship were made, there were no other images except for the pictures of the planet carried by the mecha. At that time, for the sake of the children's boredom, they let these images go many times, and they don't want to watch them now.

It was a month later, and the melting layer above was finally dug out. You should know that the airship that prospected was only used for exploration, not for excavation. Not to mention, this melting layer is a variety of metals, and the lava has been melted together. Digging downward is quite troublesome. One of the main reasons is the lack of large-scale excavation engineering machinery.

This is a large pit with a diameter of over 100 meters. When the blockage of the stones below appeared, Yang Heng breathed a sigh of relief. At this time, the airship only used a steel wire rope to lift the stones below one by one. This design is quite interesting. This is a straight up and down passage. It can be seen from the sectional view that this is an underground passage that was later modified. Originally, it was a spiral ladder-shaped passage, but that passage was directly blocked with metal, lava, and even some other substances. Obviously, these stones were added later to preserve some things, but if no one discovered these things, they would probably never appear again. You must know that no one would find five thousand meters underground.

"It's out, it's out, the baby is out." The children all surrounded them and jumped up happily. They also saw that the sectional view had reached the bottom floor, and then there was a large space.

"Yang Qing, has it really been dug up?" Li Er was excited. When he heard the children's screams, he quickly ran out of the room. You know, he was the one who was most concerned about it, although he pretended not to care.
