Ten thousand I am across the heavens

Truck drivers in the doomsday world are not much different from taxi drivers in modern society. They often have radio stations or communication channels to communicate with each other. If there is anything, they can be informed and communicated on the communication channel at the first time.

  After Lan Nuo revealed the coordinates, other truck drivers soon found out what the huge building on the surface was.

"You mean the abandoned gene bank? It was built a long time ago, but it's now abandoned. It was originally a backup of our civilization, storing a large number of fertilized eggs of various species, including humans. But in the previous disaster, the fertilized eggs were destroyed and most of the seeds were unusable, so it was abandoned."

A driver enthusiastically explained to him that this building was so eye-catching that many drivers must have seen it on the surface.

Lan Nuo nodded and continued to drive his heavy truck to the designated location to transport the mined minerals. These minerals were to be put into the heavy element fusion reactor, which was an important source of energy for the Planet Ark.

Lan Nuo silently memorized this location while driving the truck. If she had the chance to apply for a set of equipment for independent travel, she would come here to explore. Her intuition told her that this building should be the key.

……

Half a month passed, and after driving the truck dozens of times on the ground, Lan Nuo was basically familiar with the road conditions in this area and the use of this large engineering vehicle. Before setting off, Lan Nuo also called the Nangong couple.

One of them is a demon hunter, and the other is a siren. They are both races with strong survival ability, especially the latter, who is almost immortal in the ordinary human world. With the two of them, it will be safer to go out.

"Are you saying you want to take us to visit the ancient buildings on the ground?" Nangong Wudi took a sip of the alcoholic beverage specially made for this world and thought thoughtfully: "Do you also think that the people here are too weird?"

Lan Nuo nodded: "Yes, they are too kind to us. Moreover, when I was a dung collector some time ago, I found that there was very little human feces in the sewers. This may mean that the residents living here have undergone a high degree of mechanical transformation, or even robots.

I feel that this should be related to the damage to their species' gene pool. Perhaps it is precisely because of the loss of precious human gene inheritance that they have to give up their flesh and blood. My application for a visit has been approved. I received a total of three sets of protective clothing, which will facilitate our activities in the ice and snow outside. "

"We don't have much to do anyway. We work here just because we can't spare any time. Since you want to go out and take a look, let's go together. It just so happens that when we first came here, we survived in the wild for quite a while, so we have some experience in how to survive in the ice and snow."

Elsa nodded and said, "Yes, he was frozen like a dog at the time. If it weren't for my strong vitality, which kept a layer of water shield covering his body surface, I guess he would have frozen to death long ago. His ability to survive in the wild is indeed very strong."

Nangong Wudi: “…”

Elsa is no longer the lady she was when they first met. What kind of personality will a siren, a creature that almost never dies, develop in its long life? As you can imagine, it is undoubtedly a very casual existence.

"Then I'll rely on your help from now on." The three of them agreed to set out together early tomorrow morning. Lan Nuo drove them to the abandoned species gene bank.

……

On the vast white ice field, the huge tires of heavy-duty trucks weighing hundreds of tons and more than a person tall rolled over the ice, making a loud rumbling sound, and roared along the remains of roads built in ancient times towards the huge man-made buildings in the distance.

It was a tall iron-gray building. From a distance, it looked like a huge tombstone inserted into the surface of the planet, giving people a very ominous premonition.

In front of such a magnificent building, their huge heavy-loaded truck seemed extremely small. Amid the violent shaking, Elsa and Nangong Wudi looked unhappy, as if they were carsick.

"I remember the experience of falling into a blender when I first came to this world. I felt like my whole body was being shaken by you." Elsa is worthy of being a mermaid. Telling this experience would scare many people to death.

"Stop complaining. We're here. He went around looking for the door. Although this building is built on the ground, it must have taken into account the prevention of various natural disasters. The entrances are tightly sealed. I wonder if the pass in the underground shelter can still open the door here after it is abandoned?"

Lan Nuo parked the car at the door, put on protective clothing, and then jumped out of the car. Although the Nangong couple could barely survive in such a harsh natural environment, after experiencing the beating of the harsh natural environment, they still obediently put on protective clothing and jumped out of the car.

Lan Nuo took out the pass he carried with him and swiped it on the ancient gate. Although this place had been abandoned for a long time, surprisingly, there was still electricity. After swiping the pass on it, the long-dormant system slowly started up, and the isolation gate slowly opened. The heavy gate was half a meter thick and was made entirely of unknown high-strength gold. It was conceivable that when seeing this place, the defense specifications must have been very high.

The three of them walked in and found that this place was just like a spaceship. After entering, they needed to wait in a structure similar to an airtight chamber. After the outer gate was closed, they waited in the two-layer gate for a while before the inner gate opened and they officially entered this long-abandoned ancient building.

This design should be able to cope with a vacuum environment. The designer may have taken into account the possibility of a large amount of atmospheric loss from the planet during navigation, so he chose this special design similar to that of a spaceship.

Entering the inner gate, the building's internal system sensed the arrival of a visitor and started working again. The emergency dark red light finally came on, barely illuminating the space.

It can be seen that within the field of vision, there is a rather large function hall, with roads leading to different sections, and signs on the ground and the roof, indicating the different functional areas in the building. "I didn't expect that after so many years, this ancient building can still operate." Nangong Wudi couldn't help but sigh: "This is much more powerful than things on Earth. According to them, this thing has been preserved for nearly 1 years. I'm afraid that the only things that can be preserved from years ago are some oracle bones."

Nangong Wudi was just marveling at the aliens' advanced technology when his wife ruthlessly interrupted him: "That was on land, in the Siren City Nasatron, but it has been preserved until now. At least before I left the seabed, all the functions there were still intact, although we don't know how to use many of them ourselves."

Lan Nuo remembered that in the original book, the city built by the sirens on the seabed was actually built on the basis of a spaceship that sank to the bottom of the sea. However, when they traveled back in time, they basically lost their original memories, and the civilization was in a state of collapse and disintegration. Even if they gradually rebuilt the civilization later, they could not start their spaceship again. At most, they built a large shield underwater and established an independent city isolated from the world.

"Let me see... Let's go to the human gene bank here first. I asked among the drivers before, and I heard that it was because the human gene bank was damaged that this gene bank was finally abandoned."

Everyone nodded and followed the sign above their heads to enter the corresponding passage. The elevator here was ready to use. After taking the elevator to the corresponding floor, they saw the warehouse of the human gene bank. The temperature in the warehouse was quite low, basically the same as the outside temperature. This was a cold storage, and the seeds inside were preserved at low temperatures with liquid nitrogen. They should be human seeds.

Today, it seems to still be running automatically, and the pipeline for replenishing liquid nitrogen has not leaked. Interestingly, Lan Nuo discovered through observation and reading the instructions left here that all the human seeds stored here are sperm and egg cells stored separately. There are no complete fertilized eggs, which inevitably makes people wonder, not only are there no fertilized eggs, but there are also no embryos.

Logically speaking, under ultra-low temperatures, embryos that have undergone a few divisions are theoretically easier to preserve than sperm and eggs. Complete cells have the ability to divide themselves, so they are safer to store and should also be much easier to replicate.

Such embryonic cells are easier to culture and replicate. They are more suitable as seeds of civilization and can also be used to prevent the situation where in vitro fertilization cannot be completed due to lack of technology when civilization is cut off.

However, it is not certain that there are no embryos here. Perhaps this room only stores sperm and egg cells.

"Let's go to other rooms. This should be safe. My husband and I already know the language of this world." Nangong Wudi took Elsa to other rooms. Lan Nuo swiped his card and took out a can of frozen cells.

Cells preserved in an ultra-low temperature environment are almost in a state of time stopping. Theoretically, they can be preserved for a very long time. Although it may be a bit exaggerated to say that they will never be damaged, in theory, there is no problem with tens of thousands of years.

After taking out a can of frozen cells, Lan Nuo found the laboratory in this building and carefully opened the frozen container. Although someone had told him before coming that the human seeds stored here were damaged, he still wanted to take a look to confirm it.

As Lan Nuo opened the valve, a puff of white gas came out. It was liquid nitrogen used for freezing. He used a specific instrument to measure the temperature inside and confirmed that there was indeed no problem with the temperature. It was a low temperature that could preserve sperm and egg cells for a long time. Then he skillfully used the professional instruments here to take out the cells stored separately in the container, put them into the professional equipment to slowly thaw, and put them under a microscope for observation.

This process can ensure that the cell structure is not damaged during the thawing process. After a moment, Lanno took out the cells and placed them under a microscope.

During the observation process, he couldn't help but frown. The aliens' optical microscopes were not much different from those on Earth. After all, the optical principles were there, and it was difficult to make a distinction.

Lan Nuo was sure that there was nothing wrong with the steps he took when using the microscope. He observed through the microscope that these sperm and egg cells had no structural damage at least. They still looked like living cells, and the internal organelles were well preserved. They did not look like the damaged cells described.

But there is no reason for people in this world to lie to him about this kind of thing. This means that the damage may have occurred at a deeper level. This requires more professional instruments and equipment.

Fortunately, there is the most advanced biological laboratory on the planet. The corresponding equipment is not difficult to find. Lan Nuo found equipment that can perform gene sequencing in the laboratory. The arrangement order of DNA cannot be seen by a microscope, so more professional equipment is needed. Nanomachine assistance is required to detect it.

Lan Nuo carefully checked the equipment here, read the manual of the equipment, and tested the status of the equipment. This was not a microscope, and he could not guarantee that the alien equipment was easy to use. After all, nanomachines were much more valuable than clumsy equipment. If they were not maintained, they would be easily damaged. Fortunately, the nanomachines were also stored in ultra-low temperature liquid nitrogen, so they were still not damaged even after a long time.

Nangong Wudi, who had been searching for a while, looked unhappy. He had already found his way back: "We found a... um... breeding room. The situation there is... hard to describe. You'd better go and see it yourself. But be prepared. The scenes there are not something that most people can bear."

Lan Nuo nodded and said, "Wait a moment. I am inspecting this equipment and will sequence the genes of sperm and egg cells in a while."

Elsa twisted her sea snake tail and crawled over, poking her husband with the tip of her tail: "Don't you think it's a bit strange? How come Lan Nuo adapted so quickly? It seems like he can use everything."

"Maybe he was a scholar before he came here. Educated people are different." Nangong Wudi was born in a relatively ignorant and backward era, so he was more accepting of the various incredible technical abilities displayed by Lan Nuo. After all, whether it was a steam engine or a nuclear reactor, to Nangong Wudi, it was no different from magic.

After checking the equipment, Lan Nuo confirmed that there was no problem in principle and the equipment was not damaged. Then he injected the thawed cells into the equipment and started gene sequencing.
