"You are crazy, you really dare to directly send a fleet of 100,000 to travel through the undercurrent of time and space!" Sunbird Zhu Danfeng walked around in front of Zhang Jingyuan.

"Tsk tsk..." Boss Zhang was savoring the tea without any rush. Although the spaceship outside was shaking, Boss Zhang could not feel any shaking at all.

But in fact, Zhang Jingyuan was just calm on the surface, and he was indeed a little worried in his heart. It was too risky to enter the undercurrent of time and space directly. But China had to gamble, and it was nothing if it failed. At least the main migration fleet was not here - although it was the elite of China, it must be clear that the elites were only elites, and the migration fleet had a population of tens of trillions. How difficult it would be to re-screen and cultivate a group of elites. Therefore, even if the assault fleet was wiped out, the impact on China was not very big.

As for a few masters such as Zhang Jingyuan, they are also capable of escaping from the undercurrent of time and space.

But it must be admitted that if the risk is successful, you will get a lot! If you can migrate your fleet in advance to reach the Andromeda galaxy for 4,000 years, it will lay a solid foundation for the migration of China and the same important step.

This is a typical gambler psychology.

Zhu Danfeng turned around and found that Boss Zhang ignored him. Then he slammed the door and left. There were not many people who dared to face Boss Zhang like this. Even if Zhu Danfeng was one of them, you have signed a contract with me, what else can you do!

Zhu Danfeng left, Zhang Jingyuan put down the teacup, poked the consciousness out of the spaceship, and looked at the situation outside. A faint uneasiness flashed in his heart!

The outside world is rotating wildly, which is the entrance position of the space-time submerged stream; at this moment, countless spacecraft fell into it like dumplings. After years of exploration, the entrance position has expanded to a diameter of one million kilometers. It is enough for the 100,000 fleet of China to form a certain defensive formation.

In order to adapt to the environment here, all the spacecraft here use a small space below 10 kilometers to prevent space conflicts and other problems, and they also try their best to cover up the fluctuations in space. In addition, all the spacecraft have not activated the space defense technology, only simple virtual physical defense and relatively ancient energy protection layer technology - also to prevent space fluctuations.

After a while, Xiao Qingshan's message finally came. All the spacecraft had arrived and were in good condition. Although the surrounding area was rotating strongly, China had studied it for three hundred years and had almost thoroughly studied it - at least this entry point is.

Although Xiao Qingshan is the direct commander-in-chief of the fleet, he also needs to report the relevant information to Zhang Jingyuan and others; perhaps sometimes these elderly people still need to come out for emergency treatment.

The fleet only begins to move forward after completing the inspection. It is in the true internal of the space-time undercurrent, but it cannot detect the changes in space-time - being in it; but this does not mean that there is no danger, but because there is no direct investigation, it can only be indirectly detected through some data comparison, which is even more dangerous.

The fleet is moving forward day by day, and at first it is a proven route. However, as it goes deeper, some problems begin to arise. These problems are not big, but they are heartbreaking! For example, it is obviously the same spacecraft. As a result, within a month, the clocks at different positions of the spacecraft actually appear at different times. Perhaps the time difference is a few seconds, which is awesome for more than ten seconds, but don't underestimate this problem!

The most important thing in modern technology is time; the core technology of satellites entering the sky is also a matter of time! Under ultra-high speed, the gap of 0:00 seconds means an error of several kilometers!

For example, at the speed of sublight (the super-light speed technology is not required to turn on the sub-light speed technology in space-time undercurrent). A gap of hundreds of thousands of kilometers is a few seconds! The ultimate manifestation of this gap is the spacecraft stress!

In low-speed environments, people will not care about changes caused by time and speed. Moreover, although the time itself is different in every place in normal time and space, the same place is uniform, so there is no need to worry about this. But now it is different!

A spacecraft, especially under the sub-light speed, must not ignore the changes in time - but China rarely encountered such a situation before! Under the sub-light speed, time changes lead to changes in speed on the other hand; as a whole, the spacecraft must advance as a whole, and cannot advance in batches; however, different parts of the spacecraft have different speeds due to different time. If you want to balance these speeds, you must rely on the strength of the spacecraft itself! This causes the internal stress of the spacecraft (tension, pressure, distortion, impact, and even internal expansion, etc.).

This is like a tow truck. If the car in front slows down, the tow truck in the rear will hit the car in front or protect it; if the front front accelerates, the tow truck in the rear must be pulled; and similarly, if the tow truck in the rear is stuck, the tow truck in the front will also be pulled; if the tow truck in the rear suddenly accelerates (such as downhill, impact) due to external forces, it will also cause an impact on the front front; in extreme cases, if the tow truck flips, don't run away!

The current spacecraft is facing this situation, which only occurs on the time and space scale. Because of the change of time, such as the time is fast, the speed of the speed of the spacecraft will be fast, and the slow time is slow, the speed of the spacecraft will be slow. But the spacecraft is rigid, not noodles, so these changes are ultimately reflected in the overall spacecraft, which will cause various pulls on the hull of the spacecraft. Under such repeated impacts, it will inevitably lead to loose structure and metal fatigue. The final result is self-evident!

However, this comes from changes in time and space, but no defense technology can defend against it. Moreover, the larger the spacecraft, the more serious the damage it will suffer.

Even space defense technology cannot prevent changes in time - especially the current space defense in China, which is actually very primitive.

This situation was reflected in Zhang Jingyuan at the first time, but what can Boss Zhang do? It’s powerless! Immortals are also humans, not gods of creation. Besides, the practice of China is more for enjoying life, not for various powerful abilities - that is a matter of technology; with technology, immortals also have to be lazy.

Scientists and various elites gathered at the first time, and the fleet even had to find a relatively stable place to dock for the time being.

"Use a small spacecraft to move forward and turn on space defense!" Li Xianjie made adjustments immediately based on the current situation. Under the current conditions, it is a joke that you should carry out scientific research, reproduction and adjustment of the spacecraft; all you can do is to use existing technology to find safe methods bit by bit.

Soon the first 30-kilometer-sized spacecraft set off. There were only a few masters and a few elite scientists on it. The rest were unloaded and placed in other spacecraft. The spacecraft moved forward at 0.9 times the speed of light (relying on inertia) and activated the space defense technology. During the flight, the defense intensity of various space methods was continuously adjusted and improved, and the surrounding time was constantly corrected, and the surrounding safety tunnels were explored.

This flight took only one month, and the spacecraft continued to run about 800 billion kilometers.

The results are good, and the small spacecraft is indeed effective! But more than half of the spacecraft on the scene are large spacecrafts of 300-100 kilometers; and it is always turned on space defense, which is also a great challenge to energy consumption! Don’t forget that there may be battles ahead; and after leaving the space-time undercurrent, battles may also occur!

But Li Xianjie is Li Xianjie. After comprehensive consideration, he actually proposed a bold plan: a one-character long snake formation!

Well, this is really a long snake; according to this plan, it is to fly with a small unmanned spacecraft in front and explore the route; all the spacecraft behind it does not form a formation, but instead advances like a long rope. This can ensure the safety of the flight route to the greatest extent; but it reduces the safety performance of the spacecraft's fleet. Once a certain spacecraft fails, it will directly affect the entire spacecraft. The entire fleet length is extended to a length of 500 million kilometers!

"I don't know if it's feasible to reduce the speed of the spacecraft? After all, the migration fleet in the alien sky will take at least five thousand years. We can still meet them even if we fly in the space-time tunnel for 4,500 years." Xiao Qingshan is not a decoration.

Li Xianjie shook his head firmly: "It is feasible in theory, but it is not feasible in fact. First of all, although the slower the speed of the spacecraft, the smaller the pressure it bears; but the slower the speed also means that the longer the pressure it bears; once the time exceeds a certain limit, all the spacecraft will disintegrate; time itself is the biggest killer. Secondly, energy; the longer the stay, the higher our energy consumption. Finally, whether the mood of the people is taken into account; whether it takes into account such abnormal time and space for a long time is a serious challenge to our physiological conditions."

Xiao Qingshan stopped for a while, and after a long period of depression, he could only sigh deeply! According to Li Xianjie, the shorter the time, the better, and it seems that the same is true. In the space-time undercurrent, the time speed is very fast because of the distortion of space-time undercurrent. It seems that thousands of years have passed outside, but the time in the space-time undercurrent may have been thousands of years! Even tens of thousands of years are possible.

Not to mention in this strange space-time undercurrent, even in normal space, the spacecraft will work continuously for thousands of years, which is a harsh challenge! This is not a few thousand hours, a few thousand days, but a few thousand years!
