One of the main reasons why Xu Ran was able to survive in the fragmented city was that it was on the space key.

It's all because when Xu Ran touches the space key, his body is affected by the -y energy factor in the space key, and his body will also secrete this energy substance.

In addition, during the teleportation process, the space key is squeezed by the power of space, which will force the -y energy to grow rapidly, and at the same time, it will also stimulate the -y energy in Xu Ran's body to grow rapidly.

The more times Xu Ran performed spatial teleportation, the more this energy factor would accumulate in his body.

In addition, human beings themselves are different from other organisms, the metabolic mechanism is strong, and those -y energy factors have strong adaptability to the human environment, and will be enhanced and integrated into the human body with the change of Xu Ran's physical fitness, thus becoming a part of Xu Ran's body, forming a unique human evolution mechanism system.

This -y energy factor, when the laboratory researched it, Xu Ran temporarily gave this energy factor a term that human beings would often mention, potential.

Because he will stimulate the metabolism and physiological circulatory mechanism in Xu Ran's body, so as to promote Xu Ran's physical fitness to become stronger and more adaptable to the environment, so as to stimulate some evolutionary potential that human beings do not have, this kind of -y energy factor is called potential, which is extremely appropriate.

The mutant creatures in the biological garden were originally injected with the -y secretion material extracted from Xu Ran's body and fused with other matching substances, and artificially caused them to undergo genetic changes, so that they also had the -y energy factor in their bodies, so that they could survive here.

It's just that the size of those creatures is too small, and they are very different from human bodies, and the absorption rate of the -Y factor in their bodies is very low, so the accumulation is very small, so they can only stay in the biological garden, and they can't survive in the fragmented city environment for a long time.

Theoretically, if Xu Ran injected other humans with this -y energy factor, after the substance he called potential, there was a possibility that other humans would be able to survive in this fragmented city.

It's just that this kind of method of experimenting with living people, Xu Ran never dares to try it easily, which involves his bottom line of life.

Now in the fragmented city, whether flying in the sky or running on the ground, there are robots everywhere.

According to the statistics of housekeeper An'an, the number of robots currently in work has reached 6,000, and there are 1,000 in reserve.

The work of all robots is distributed in an orderly and unified manner, and the division of labor is reasonable, so there will be no interference with each other in any work, and there is no waste of robot resources at all.

Each robot here has its own purpose, and the type of work it does is completely different.

Even if there is a new work demand, it will not be temporarily deployed as in the past, but will be coded and deployed in the robot reserve to authorize the division of labor.

At present, there are three main cores of fragmented cities.

One is the Artificial Intelligence Center, the other is the Robotics Experiment Center, and the third is the Unisplendour Research Center.

Of the three places, one is to study aspects such as robot control, as well as intelligent logic and evolution.

The other is mainly to use artificial intelligence to study the scientific research tree of the Blue Star World where this fragmented city is located, as well as some black technologies obtained from other sources.

The third core, as the name suggests, is to research, utilize and transform the mysterious purple light that will appear regularly in the fragmented city, and become a strategic resource that can be used by the fragmented city.

Since the alien spaceship performed the last crazy signal launch, but was intercepted and destroyed by the mysterious purple nebula, and the alien spaceship was dismantled by the robot, the violet light scanning, which had been irregular before, is now back to normal.

It's just that the discovery of the alien spaceship, the purple nebula that appeared at the same time, and the mysterious existence in the purple nebula, all gave Xu Ran a sense of urgency.

He didn't know what kind of existence existed in the universe outside this space, whether they were monitoring everything in this fragmented space and letting it develop freely with tacit approval.

But this was the planet where humans used to live, but the entire planet has been shattered, and humanity has been extinct, leaving only a small piece of debris space protected by earth-core energy and dust energy to survive in this universe.

Xu Ran didn't know if the mysterious existence in the nebula was not friendly to humans or other carbon-based lifeforms, and might even be enemies, otherwise it would not have been able to suppress and destroy the alien escape spacecraft with a thunderbolt when it sent out a signal wave.

However, Xu Ran also had a doubt, if the mysterious existence was hostile and unfriendly to humans, then he often appeared in the fragmented space, and if the mysterious existence could be detected, maybe even this fragmented space would be destroyed together.

Moreover, this fragmented space is the human civilization of the Blue Star World, but after Xu Ran's exploration and summary, he found that this place is also inextricably linked with the human civilization on the earth.

Just like the space key on Xu Ran's body, it was discovered from the earth, and there are some other related mysterious existences, and similar traces can be found on the earth.

I don't know what the cause of all this is, and this needs Xu Ran to explore the universe here in the future to find the answer.

Xu Ran entered the fragmented city this time, in addition to the large quantities of materials he brought in, he also regularly provided water resources here.

The water resources extraction points on the earth, in addition to the small freshwater resources extraction points set up by Xu Ran in Jiangcheng in China, the most important large amount of seawater resources are from the underground base of Tridoran Island.

At the freshwater resources extraction point in Jiangcheng, there are also special robots in charge of their duties, which will take fresh water resources in the river in advance and store them in the water droplet storage device.

Today, however, the main industrial water used in the fragmented cities is seawater resources, and freshwater resources are stored for experiments and other research purposes.

And the extraction of seawater resources is now more convenient for Xu Ran, since the underground base of Tridoran Island has been built.

An automatic water storage system has been built there, and there is no need for robots to do so, and the automatic water storage system will regularly store a large amount of seawater into a large space of water droplet reservoirs, and all the water droplet reservoirs will be full.

In the past, in order to solve the problem of water resources, Xu Ran was not asked to be a water delivery worker, and in order to be lazy, Xu Ran never let the artificial intelligence experimental center stop the research and development of water resource storage equipment.

Nowadays, using the combination of quantum technology and space technology, four types of water droplet storage devices have been developed, which have a larger water storage space.

A small water droplet reservoir that looks the size of a quail egg can store up to 10 million cubic meters of water at a time, but it is still being developed and improved in the experimental center.
