Busy and busy, but Chu Tianjiang lived a very fulfilling life.

The two years spent in the second home can be said to be the happiest two years after Chu Tianjiang fought a decisive battle with Williams and came back from the dead. Every day, in addition to training with the ten army commanders selected by Zhang Xiaogang, Chu Tianjiang had enough time to spend with his family. Although Nicol and Clara both feel that their lives are very comfortable now, and there is no need to have several children to make their lives more fulfilling, Chu Tianjiang is also very satisfied, because he also knows that with his current situation, it is not suitable to have children of his own.

In fact, except for Zhang Xiaogang and Luo Jinyong and others, no one knows the true identity of Chu Tianjiang.

In the second home, Chu Tianjiang was just an ordinary person, at most he had a very special relationship with the management authorities and enjoyed many privileges.

Restoring the identity of an ordinary person made Chu Tianjiang feel very comfortable.

No matter how famous he is on the first star, Chu Tianjiang prefers a peaceful life rather than thinking about things related to the survival of human civilization all day long.

More importantly, in his second home, Chu Tianjiang found a sense of belonging.

Not only living in human society, but also related to Zhang Xiaogang's special arrangement. That is, on a smaller planet of the secondary star, a home was established for Chu Tianjiang, a home that was exactly the same as the home of the river valley, and others were forbidden to go to this planet.

For Chu Tianjiang, this is his home.

Although Chu Tianjiang knew that this was not the earth, and the earth he was familiar with had long been unrecognizable, this home was almost the same as the river valley home he was familiar with. To this end, Zhang Xiaogang even made a lot of effort, such as by adjusting the star core, to transform the planet's environment so that it is almost exactly the same as the earth. The purpose of this is simply to create an Earthly atmosphere on the surface of the planet, such as planting some plants from Earth, creating a gravitational field similar to Earth, and a natural landscape where the sun rises and sets. Chu Tianjiang felt that it was a bit troublesome to do this, but in Zhang Xiaogang's words, this was the reward he deserved.

In the past two years, the second home has also undergone drastic changes.

The full exploitation of the first colonized star system has given many people a taste of benefits, especially those citizens who wish to gain the right to reproduce through exploration. As a result, by the time the Authority announced its readiness to wage the next war, more than five trillion citizens had signed up to pioneer the colonies. That is, half of the citizens of the second home want to settle in the colonies in exchange for the right to reproduce.

Zhang Xiaogang had long expected such a situation and had already made arrangements.

In the past two years, the management authorities have selected 1 trillion yuan of applicants with the best quality from among the 5 trillion applicants through lottery and assessment, and trained them.

Of course, this is also a lesson learned.

In the development of the first colonized star system, many unexpected problems were exposed. For example, the colonists' abilities and skills revealed a lot of problems when transforming the stars, and they had to control the military power of the original owner's intelligent civilization. This shows that colonists also need to be strong enough individually, and more advanced techniques are needed to improve colonization efficiency.

Improving the colonist's personal abilities is not a big deal, just get enough cores, or simply replace the mass with them.

The key lies in the techniques involved in colonization.

Among them, the most important is space bridge technology.

Using the space bridge made by Ali can allow colonists to reach the colony, but it is too inefficient to use it to transport supplies. To put it simply, the most important material for building a colony is the star core, and in order for the star core to pass through the space bridge, it must be directly controlled by personnel. If it is not controlled, send the star core into the space bridge, then the star core will be completely dissipated before it passes.

It's just that it's not easy to solve this problem.

At the beginning, Zhang Xiaogang proposed that more people should master the space bridge technology, which could reduce Ali's burden and make her no longer worry about trivial matters, and second, to improve transportation efficiency, speed up the construction of the colony, and develop the speed of the colony.

Unfortunately, this is almost impossible.

Ali said very simply, the three-dimensional universe has been formed, and the space bridge technique involves the core technology of the great civilization, and it is not something she can give if she wants to. The point is that there are subtle differences between the galaxies created by different creators, and this difference limits the use of space bridge technology. Although humans can master Ali's space bridge technique, they can only use it in the star system created by Ali. As long as it comes to the star systems created by other creators, it must be Ali's intervention, and only Ali has this ability. As for the technique of creating a space bridge, because it is based on the core technology of a great civilization, it is impossible for a human individual to master it.

In fact, none of the intelligent civilizations in the Three Micro Universes were able to master this kind of technique.

In a sense, this is also the main difference between the intelligent civilization and the great civilization in the space of the three micro-universes, and it is also the fundamental guarantee for the lofty status of the great civilization.

To be more precise, if there is no great civilization, the intelligent civilization in the three micro-universes will be finished.

With the speed of light being limited, the distance between star systems is almost an insurmountable barrier, let alone the distance between star systems. Without space bridges, any intelligent civilization can only control the star systems created by the same creator, and at most can only occupy a few surrounding star systems, and the resources in these star systems are limited, which cannot meet the development and expansion needs of intelligent civilizations. What's more, as the pace of external expansion gets farther and farther, the impact of distance will become more and more obvious, such as the consumption of more and more resources for expansion, and the resources in each star system will continue to decrease. After reaching the limit, the resources consumed for expansion will exceed the resources obtained for expansion, so no intelligent civilization can continue to grow through expansion. At the end of the day, the distant distances between galaxies, the continuous reduction of resources and the irreversible time will become the shackles around the necks of all intelligent civilizations. The only way to solve this problem is the space bridge mastered by the great civilization.

It is precisely because of this that the intelligent civilization in the space of the three micro-universes is inseparable from the great civilization.

It's just that it's not impossible to overcome this problem.

After learning the details from Ali and knowing that the Dao Space Bridge Technique was the core technique that the Great Civilization had to control, Luo Jinyong proposed a solution that even Ali was surprised by. That is, to keep the space bridge built by Ali always on.

After Luo Jinyong proposed this method, Ali was shocked, and immediately said that this is absolutely impossible.

The reason is very simple, the core of the space bridge is actually parallel space technology, that is, the use of parallel space to connect two distant places in the three-dimensional universe. The problem that arises is that in the open state, the space bridge will absorb the matter and energy of the three-dimensional universe. If the space bridge is always open, it will inevitably lead to an imbalance in the three-dimensional universe, and even lead to the collapse of space.

Needless to say, the result is simply unimaginable.

Even if there are infinite parallel spaces, the three-dimensional universe is unique, and it is the home of all intelligent civilizations.

If the three-dimensional universe overlaps with the parallel universe, it will be an unprecedented disaster.

Just when everyone thought it wouldn't work, Luo Jinyong came up with an unbelievable idea to reverse connect the two space bridges together. What made Chu Tianjiang and Zhang Xiaogang even more unbelievable was that Ali actually thought that the method proposed by Luo Jinyong would work.

It is precisely because of this that Arley has built two spatial bridges between his second home and the first colony.

According to the method proposed by Luo Jinyong, the two space bridges are reversed to dock, and a subspace is set up at each end, and the subspace at both ends is opened at the same time when in use, so as to ensure that the space bridge will not absorb the energy and matter in the universe, and will not cause serious space distortion.

The experimental results proved the theory proposed by Luo Jinyong.

The two reversed space bridges have been in existence for half a year and have been very stable and have not negatively affected the two star systems.

Of course, this two-way space bridge has been in play.

Once completed, the Second Home will use this two-way space bridge to send personnel to the First Colony, which in turn will return the mined cores to the Second Home.

This technique can also be used between the Second Home and other star systems.

Of course, this technique also solves the problem of building a certain star system into a headquarters for external expansion, which is specially used to station the military power of human civilization. If the system is large enough, it can also be used to station colonists sent to colonies.

It was precisely because of this that Zhang Xiaogang transferred the corps headquarters to the third homeland.

This is the extremely unstable star system, but large enough and structurally complex to effectively hide the military power stationed within. You must know that the human race no longer has one legion, but ten legions, each of which is 10,000 people. Although in terms of numbers, the military strength of the human race is not huge, but in terms of combat effectiveness, it definitely surpasses all the intelligent civilizations in the vicinity.

In the early stage of dimensionality reduction, it is difficult to imagine that an intelligent civilization in the three-micro universe space can have such military power.

You must know that this is a hundred thousand warriors with a ninth-level composite star core. In the early stage of dimensionality reduction, there were only a few hundred thousand family members in the Becca family with ninth-level composite star cores.

Two years is not a short time, it is not too long, it will pass quickly, and a new war is coming.
