Speaking of the clansmen of Ulantis, Lin Yifan told Mrs. Lin about the Lanxin Legion. When Mrs. Lin heard that she had found so many clansmen, and that she had also found the daughter of a minister, she was very excited.

In the past few decades, she has been taking Lin Yifan to escape from the pursuit of the overlord forces. In addition to Lin Yifan, there were only Tis and Xingsheng on the battleship, but the two of them were not from Ulantis, but the energy lifeforms created by Queen Ulantis.

Mrs. Lin hadn't seen her own people for decades, and now she cried with excitement when she learned that Lin Yifan had found so many.

Lin Yifan also asked Mrs. Lin about the energy guard, hoping to learn more about the specific situation from her.

But what Lin Yifan didn't expect was that Mrs. Lin didn't know that there were energy guards in the crystal stone, she only knew that there was something sealed in the crystal stone that could protect the crystal stone, but she didn't know what it was.

Lin Yifan summoned four energy guards, and Mrs. Lin was very shocked when she saw these energy lifeforms.

Madame Lin could feel the power of the energy guards, and they possessed infinite energy, which made her heart that she had been choosing finally let go.

With so many powerful energy guards, Lin Yifan's safety would not be a problem. Madam Lin was well aware of the power of the energy lifeforms, and she was very confident in these guards.

For the next few days, Lin Zhiyuan and his wife did not go to work. Lin Yifan has been by their side for the past few days, and the next time they leave, they may not be able to see each other for a long time, Lin Yifan wants to talk to them more.

A week later, Lin Zhiyuan and his wife returned to the Institute of Science and Technology and began their intense work. And Lin Yifan also began to implement his plan, striving to improve the Federation's combat power to a third-level technology within half a year.

The federation also made a very big determination this time, and the chairman of the Supreme Council and Li Aiguo, who mobilized the elites from all walks of life, all threw themselves into the construction.

Military, agricultural, industrial, aerospace science and technology, biotechnology, electronic science and technology and other fields have developed in an all-round way. In order to speed up the process, the federation has also recruited many high-achieving students from major colleges and universities to join.

The progress of science and technology in all fields has greatly improved the lives of the common people. The territory of the Federation has undergone earth-shaking changes, which are somewhat unacceptable to the common people.

There are many cities that are built in a very advanced way, even beyond what is described in science fiction. The development of biotechnology has made those intractable diseases as easy to treat as a cold.

Through the popularization of all walks of life in the media, biotechnology has been recognized by the general public. Now the common people are lining up to buy life elixirs, just ask that person who doesn't want to live long.

Especially when your standard of living improves, you don't have to work hard for life, you don't have to suffer from illness, and people start to enjoy life.

In various parts of the people, the people spontaneously organize all kinds of activities, including literature and art, fitness, and collective travel to browse the scenery of various places, and the rich and colorful life makes the people very happy.

While enjoying life, the Federation did not forget to strengthen military propaganda. The government media regularly publicizes the current situation to the common people, so that the common people do not blindly just enjoy life, and forget about the evil forces that are eyeing the stars.

Becoming a soldier has become the dream of many young people. Young people are full of enthusiasm and want to serve the country and show their strength.

To this end, the Federation has proposed a series of plans to increase the number of troops. The families of all soldiers who have successfully enlisted in the army enjoy certain preferential treatment.

If you make military achievements, you will enjoy higher treatment. If they die on the battlefield, the family will enjoy the excellent benefits of the Commonwealth for the rest of their lives, and the elderly parents will be cared for until they die a natural death.

Speaking of which, a new problem has arisen here, which is plaguing many families of fighters.

With the life elixir, the life of the parents has increased significantly, and if the child dies in battle, the old couple will be lonely for the rest of their lives, which is also a tangled place.

To this end, the federation has added a new regulation, the family is an only child and the parents are old, they are not allowed to participate in the front-line troops, and can enter the logistics department to serve.

In addition, the federation also encourages ordinary people to have more offspring, and the federation is ready to push the population base to a new height.

In fact, the above problems can be solved after the improvement of artificial intelligence. The front-line battles are all handled by intelligent robots, and humans only need to take charge and command.

However, the Federation did not neglect the training of fighters because of the development of artificial intelligence technology. On the contrary, the Federation has also increased the intensity of training and subjects in order to meet the needs of future wars.

The Federation has officially established the Warframe Corps, the Kamikaze Task Force, and the Falcon Task Force, which are currently the only units fully equipped with Warframes.

In the coming days, the Federation will continue to expand these two teams. And to train more excellent commanders, the Federation must build a force with strong combat power and super comprehensive quality.

The Qilin Warframe and the Falcon Warframe, after being fully upgraded, are still the preferred equipment of the Warframe Corps.

At the same time, the Federation also compiled the medical armor soldiers in Lin Yifan's crystal stone, or intelligent medical robots, into the armor corps.

With these intelligent Warframes that can fight and heal alone, the survivability of the Falcon Task Force and Kamikaze will be greatly increased.

For the safety of his mother, Lin Yifan also helped the Federation build ten Ice Phoenix Battleships. With the Ice Phoenix battleship, the mobility of the Federation fleet is greatly improved, and it can also fight across galaxies.

A quasi-first-level scientific and technological civilization, after decades of rapid development, has now nearly entered the third-level scientific and technological level. In particular, the rapid development of the federation in the past few months has exceeded the imagination of the federal leadership.

Although the situation of the Federation in this battle was quite dangerous, the final result was a great benefit to the Federation.

Not to mention the countless wreckage of warships, the more than 90 small and medium-sized flagships alone have raised the combat power of the Federation by several notches.

All of these flagships have been pulled down in the spaceport of the asteroid belt, where Tis will give them a full upgrade.

The upgrade of dozens of flagships is a huge project, and it will take at least five years to upgrade all of these flagships to Level 3 technology.

It is impossible for Lin Yifan to wait so long on the earth, so Tis has equipped the Federation with a super artificial intelligence system, and the future transformation and management of warships will all be completed by this super artificial intelligence.

The federation has fully entered the third-level science and technology field, which makes the bigwigs of the federation breathe a sigh of relief. They don't have to worry about pirates or some small and medium-sized forces invading, now they have the absolute combat power to destroy them.

Half a year passed quickly, and during this half year, the federation was greatly developed. Now all areas are on track to normal, and there is no need for the team at Teess to assist them.

It's time for Lin Yifan to leave the earth, there are still many things waiting for him to do. Although they are reluctant to leave the earth, the current situation makes it impossible for them to live in such a comfortable life.

Within half a year, Lin Yifan received a message from Lan Xin. The scuffle between those small and medium-sized forces is now out of control.

Some forces have taken advantage of this scuffle to plunder resources everywhere. The contradictions between the various forces are continuing to increase, and even the hegemonic forces behind them are a little unable to sit still.

The conflict between the hegemonic forces is not good for Lin Yifan, at least not for now. He still has a few crystal stones that have not yet been found, and now that there is a conflict, it will be difficult for Lin Yifan to get close to those planets.

Lin Yifan had to find those crystal stones before these overlord forces completely broke out into war. He ordered Tis and her team to hand over to the Federation as soon as possible, and for the Federation's engineers and scientists to take over the ship's modification.

Half a year is not a long time, but it is not a short time. Lin Yifan, Lin Nan and Wang Xiaopang were reluctant to leave their hometown where they were born and raised.

Before leaving, the Federation held another banquet for Lin Yifan and them. The first is to thank Lin Yifan for his help to the Federation, and the second is to let relatives and friends get together at the end.

Lin Yifan doesn't know when he will come back, maybe a few years or decades.

Although the life expectancy of their relatives has increased, they cannot see their relatives for endless years, and the pain of longing can only be experienced by themselves.
