Although Wu Han took the lead in making arrangements, the plan did not change quickly and things did not go as smoothly as planned in advance.

The structure of the new engine is simple and there is no difficulty in manufacturing. However, for the sake of confidentiality, the engine structure is designed very complex, but 90% of the structure is created to confuse the public and is useless at all. The actual part is less than 10%.

Because of the complex structure and the inability to reduce the accuracy during manufacturing, the new engine, which originally took only a few minutes, was extended to one week before the finished product was taken out. It was installed at the first time for the Skyhawk and the warships stationed at Saturn. Next were four warships stationed at the moon base.

In addition, all the engines planned to be installed on the Star Gate garrison warship were sent to the Skyhawk.

In addition to the above warships, the military also has four warships stationed at the Giant Star and Yin and Yang Star, which together are exactly the Ten Eagles and Ten Harriers new warships.

Twenty warships will form the backbone of the Chinese fleet. Originally, the military needed at least three-digit warships to effectively form sufficient strategic advantages, but qualitative changes will occur after all warships are installed with new engines.

A fleet with rapid transfer ability will have a speed advantage that no country can imagine. Within dozens of light years currently occupied by humans, no matter where abnormal situations occur, the Chinese fleet can arrive within a few days, thereby forming a truly rapid response fleet.

In addition, the fleet consisting of old and old ships is only four Yanjing-class battleships left by Proxima Centauri.

These four main battleships were originally planned to be sold to Russia, but because the human fleet completely defeated the fleet of the exoskeletons, countries no longer had the urgent need for warships. Russia suspended the ship purchase plan, and China almost broke the local warships. Fortunately, some countries wanted to organize fleets but were not short of money. After arduous negotiations, the military finally sold all the remaining warships.

However, the price of the four main battleships is too high, so there has been no buyer. So in the past few days, Proxima Centauri has taken advantage of its residual heat - the military plans to dismantle the weapons from the four battleships and transform them into mobile mining bases!

There are many planets near the Centaur alpha triad, and they have a large amount of mineral resources worth mining. China has established a mining base in Proxima Centauri. It won’t take long to provide a large amount of mineral resources for the increasingly depleted solar system.

Not only China is trying to fight Centaur Alpha, but the United States, Russia and Europe also have their own plans. However, neither side does have the cruel courage of China and directly transforms old warships. After dismantling weapons and most of the armor, fourteen to fifteen kilometers of space can be freed up in the seventeen-kilometer warship. However, because the power system and propulsion system must be retained, the space that can be used is just over ten kilometers.

A transformed Yanjing-class battleship is a mobile industrial base. It can provide a complete set of industrial equipment from mining to smelting to processing. It is a necessary magic weapon for developing colonial stars, going to deep space, and mining resources outside the solar system!

Currently, only one warship has been transformed. It was originally planned to deploy the second base ship on the Superstar to contribute to the construction of the Giant Star. However, after discovering the neutron star, Wu Han persuaded the senior management to transform the remaining three main battleships at the same time and deploy all three base ships in the neutron galaxy!

Although the status of the Giant Star is important, what is important is that it has a good colonial environment, and in contrast, it lacks a large number of resources for industrial development.

After several years of development, Giant Star has built a supporting industrial system that can provide some light industrial products for Giant Star immigrants.

If you pay a little attention to the development of Giant Star, you will find that there is no heavy industry there. The only thing that can be associated with heavy industry is the synchronous orbit base of the garrison fleet.

China does this. Its external caliber is to protect the natural environment, but the real reason is that it is from the strategy of strong trunks and weak branches. It does not build heavy industries on Giant Star to avoid the situation of strong trunks and weak branches, which will eventually lead to the division of the country.

China is fundamentally just one of hundreds of countries around the world. Even if its military and national strength are the best in the world, it cannot reproduce the glory of ancient feudal dynasties in expanding territory.

However, the outer enclave is a whole planet with good conditions. It is more suitable to be the center of the country than the local area. Now the local area can still control the enclave with the accumulated foundation of thousands of years, but what will happen in a few decades? What will happen in a few hundred years?

If colonial stars are not restricted, there may be signs of division within decades.

And this is only one reason, and the other is the distance between the giant star and the solar system.

Everyone knows that the farther the distance is, the more difficult it is to communicate with each other and the higher the possibility of separation.

The distance of twenty-nine light years is 76 times the speed of light, and it takes more than four months to fly over. It takes more than half a year to travel once, which greatly reduces the local control over the giant star.

The local government can still use the method of stumbling the colony star to control it, but what if the colony star develops? It would be nice if the colony star does not interfere with the local neck.

Fortunately, the pink crystal brought back by Ye Fei solved this problem. The modified Skyhawk flew at the highest speed and only took thirty hours to reach the Giant Star. Even if the speed was limited according to Wu Han's intention, it would only take one month. Although it was still unsatisfactory, it was much better than before.

Therefore, the development of crystals has been included in the national key strategy, which is also the main reason why Wu Han convinced the senior management.

In addition to the new engine, the transformation of the new laser is also very simple, but there are thousands of lasers installed on a warship, which cannot be modified in a short while. In addition, the number of crystals transported by the Skyhawk is too small and must be used for research. Therefore, the transformation plan for the laser cannon will be carried out after the warship returns to the neutron galaxy.

Ye Fei originally wanted to take advantage of the opportunity of the warship to undergo transformation and return to Earth for a while, but failed to do so. He thought he would not have the chance to go home to see him this time. Unexpectedly, the Saturn base had only completed the research on robots, but it only used as a technical reserve and did not carry out large-scale manufacturing. If the Skyhawk wanted to bring enough robots with him, he had to wait for a while.

Ye Fei happily brought all the officers and soldiers of the ship back to earth and reunited with his family for half a month.

In recent years, there has been no threat from the external bones, but Ye Fei always flies everywhere without touching the ground. It is nonsense to say that there is no complaint at all at home. Gao Lan wants to apply for transfer to the Sky Eagle several times, and the application can be approved by 100%, but the twelve-year-old Ye Qi has already started to go to junior high school. As a mother, Gao Lan is reluctant to leave the child.

Military warships can make room for soldiers' spouses, but they will not consider the issue of children for a while.

In the past few days, Qian Liguo has not forgotten to send several Harrier-class warships to send the new engines to Giant Star and Proxima Centauri. However, due to the slowdown, only Proxima Centauri's four industrial base ships received the engines. After the modification is completed, three of them will set off for the Star Gate. Move the modification work originally completed in Centauri α to the neutron galaxy.

Half a month later, Saturn's base will gather all the robots needed, and the officers and soldiers of the ship will gather together again, and will return to the neutron galaxy.

But unexpectedly, two soldiers who returned to Earth for vacation had problems. They had not returned after the time to return to the team, and they could not contact them in any way!

This situation attracted the attention of the military. The military intelligence department immediately intervened in the investigation.

But the Skyhawk did not stay for much because of this accident and still left the solar system as planned.

In addition to the cargo carried on the ship, there were twelve additional researchers, the youngest was over 60 years old, and the oldest was over 110 years old.

In addition, in order to accelerate the construction of neutron stars, the military also sent Ye Fei a modified transport ship. The transport ship that runs through the new design concept can fly alone or be connected with the Skyhawk to form an extended warship with transportation modules.

The Sky Eagle quietly came back and left quietly, without making any big fuss or deliberately concealing it, as if nothing was abnormal.

In fact, any warship of the military is the focus of attention of the intelligence departments of various countries. Although the Sky Eagle is low-key, it still inevitably attracts the attention of the intelligence departments of various countries.

Because the Skyhawk has been docked at the Saturn base, the military has kept everything strictly confidential, and these powerful intelligence departments have not been able to obtain any information returned by the Skyhawk this time!

In the past, no matter how well it was kept confidential, it could have obtained some useful information and no information could be found. This itself represents an abnormal situation.

The intelligence department with a keen sense of smell also focused its attention on the Skyhawk. Although there are some intelligence personnel from other countries in the Saturn base, few people can access high-level secrets. Even if they can access, they do not have the ability to send the information out.

So these intelligence departments set their minds on the Sky Eagle officers and soldiers who returned to Earth and brazenly carried out secret kidnapping.

However, China's National Security Bureau is not a vegetarian. Intelligence departments of various countries have always been cautious in their tails. Suddenly, frequent activities naturally attracted the attention of the Security Bureau. The two sides secretly engaged in a fierce secret battle. Without the knowledge of the Sky Eagle officers and soldiers, dozens of black hands stretched towards the officers and soldiers were cut off.

Unfortunately, they were finally able to succeed.

The enemy who had found the treasure immediately conducted an assault interrogation of the two soldiers and directly injected the real agent.

But Ye Fei did a good job of keeping secrets. There were only a few people who were informed on the Sky Eagle. Except for him, they all stayed at the Saturn base. In the end, only the news of China's discovery of neutron stars was leaked, and nothing else was gained.

If they ask about the departure and arrival time of the Skyhawk, they will immediately find that China's aerospace technology has made a new breakthrough. Unfortunately, the guy who interrogated did not expect this.

It was not until one morning after the Skyhawk left that two unconscious soldiers were discovered by residents who were getting up early to practice.

After arriving, the police determined the identities of the two people and sent them to the hospital for treatment as quickly as possible. The examination found that a large amount of spitting agent in the blood of the two people remained. After full rescue, the two woke up one after another three days, but neither of them remembered what had happened in the past few days.

The snoring agent is actually a special anesthetic agent. The nervous system of two people is affected by excessive injection of anesthetic agent and is no longer suitable for serving on warships, so they can only call out the fleet in disgrace.

But this matter is not over, and the military's intelligence department launched a series of retaliation operations.

Secret war is not a fight against the Ministry of Justice, so there is no need for evidence. Just know who did it. For a time, the intelligence departments secretly dispatched by various countries in China were in panic, and the total number of military officers deported exceeded 20.

But all this has nothing to do with the Sky Eagle. After leaving the solar system, the warship lowered its speed and flew towards the star gate at a light year every day. The previous two months of voyage had been shortened to twelve days. But Ye Fei still felt that the speed was too slow.

After leaving behind the new engine, the Skyhawk plunged into the nebula. When he arrived here, Ye Fei no longer suppressed the speed of the warship. It took him several hours to fly to the neutron star.

The twelve-man research team immediately started the research and in order to carry the equipment needed for the research, the Skyhawk even had to give up some of the missiles to spare enough space.

Thousands of robots and some of the equipment carried on the ship were sent to Chixing by the landing ship. The robot immediately started working according to the degree, began to look for mineral veins, and built Chixing Industrial Base as planned at the most suitable location.

The efficiency of robots is far from comparable to that of humans. The modularly designed industrial bases rose up almost at a speed visible to the naked eye. Then unmanned mining equipment began large-scale mining work.

At the same time, another batch of robots and equipment was sent to Silver Star, which will become a production base for robots in the near future. After manufacturing enough robots, it will be expanded into a real heavy industry star.

It takes a certain amount of time to expand the scale of mineral mining on the Red Star, while the resources contained in the Milky Way of Silver Star are relatively single, and the development of the two planets is launched at the same time. It can complement each other's advantages.

The transport ship that departed from the Sky Eagle remained above the Silver Star orbit and would be responsible for the task of transporting robots to the Red Star.

However, neither the Red Star nor the Silver Star is anything to be considered. The only ones that are truly valued are the super heavy elements in the asteroid belt!

The engineering ships that had all changed all the personnel entered the asteroid belt as soon as possible, and made every effort to mine green crystals to prepare for the renewal of the Skyhawk's laser cannon.

In just one day, all the work was put on track and everything was unfolding in an orderly manner.

Half a month later, three Yanjing-class warships flew to the neutron galaxy. One of them had completed one-third of the transformation, and the other two had not yet begun the transformation. Ye Fei sent all three warships over Silver Star and would use the resources of Silver Star to complete the equipment transformation.

As long as Silver Star’s robot construction enters orbit, as the number of robots increases, the development speed of neutron galaxies will become faster and faster.

Just when everything seemed to be on the right track, Dr. Liang from the research group suddenly put down his research and came to find Ye Fei in person.

Non-military personnel like Dr. Liang must not enter the bridge. Ye Fei met with Dr. Liang in the captain's office and poured Dr. Liang a cup of Longjing tea that he had only drank once.

This thing was given by Jiang Yufei when he returned home a while ago, saying it was some authentic good tea. But Ye Fei couldn't feel any good when he drank it in his mouth.

Dr. Liang, whose hair was already white, put the teacup aside and said straight to the point: "Captain Ye, I'm here to find you a big matter of life and death."

Ye Fei wanted to laugh secretly, but in just a few days he brought the life and death to say something. But he was very polite: "Dr. Liang, you are too polite, just call me Xiao Ye." Ye Fei has enough reason to respect Dr. Liang, no matter in terms of age or knowledge.

Dr. Liang nodded bluntly: "Xiao Ye, I mainly study neutron stars. I believe you also know the situation of this neutron star. According to my preliminary calculations, we only have five years at most."

"What?" Ye Fei didn't understand what Dr. Liang meant, "What five years?"

Dr. Liang patiently explained: "I mean the neutron star, the giant planet that revolves around the neutron star, is approaching the neutron star like the nearby nebula. In five years, the distance between the two stars will be close to the critical value." He stretched out his big palm and stretched his five fingers straight.

"You mean, that giant planet may crash into a neutron star?" Ye Fei immediately seized the key.

"Yes, that's what I mean," said Dr. Liang.

Dr. Liang was straightforward, and Ye Fei also said bluntly: "Doctor, I am a soldier and don't understand complex astronomy. Just tell me what will happen after the impact? Will neutron stars turn into black holes?"

"That won't be." Dr. Liang shook his head, "The mass of a giant planet is not enough, and the impact will not produce a black hole. But after all, it is a collision between a giant planet and a neutron star. The impact will release huge energy in the form of strong light and strong rays. At that time, no matter how good the protection is, people in this galaxy will be exposed to violent radiation, and the electronic equipment on the robot will be burned by strong rays."

Ye Fei immediately breathed a sigh of relief when he heard this: "That's all?" It's just a strong light and rays, just avoid it?

"That's it?" Dr. Liang suddenly widened his eyes, "Captain Ye, you don't take human life seriously."

"Calm down! Calm down first!" Ye Fei quickly comforted the old man, "Isn't it just a collision? Then we can just withdraw early?"

"You said it easily, how can things be that simple?" Dr. Liang finally knew Ye Fei's astronomy level. "Neutron stars are an unprecedented research topic. We don't know the specific impact time at all. We can only calculate the possibility within five years. After more than five years, it is impossible to determine whether to impact immediately or in ten years!"

"Oh, so that's it." Ye Fei nodded, "That's nothing. We can find a way to get the impact ahead of time and come back after the impact is over, wouldn't it be enough?"
Chapter completed!
