Su Jiao spent three years cracking the weapon of the energy body, and finally found an alternative energy source.

So far, Huaguo's ground transportation architecture and sky transportation architecture have been completed.

The basic defenses have also been upgraded to state-of-the-art technology.

The textbooks are also updated at the same time, and a lot of theoretical knowledge is explained by Su Jiao and Qin Lanzhou before it is submitted to the education department.

Nowadays, the Ministry of Education has a group of scholars who specialize in the study of civilized science and technology, and Su Jiao and Qin Lanzhou occasionally make cameos to discuss future science and technology with them.

Huaguo took the lead in entering the third-level civilization stability period, and the rest of the countries under the leadership of Huaguo have also improved their science and technology rapidly, but they are still much worse than Huaguo, but now the entire planet has formed a defense team to be responsible for the security of the star fields around the Blue Star.

Qin Lanzhou is responsible for training this team, and every six months, a new group of people will go to the sky to patrol.

Whenever there is danger, they signal to the ground.

On top of the connecting station, Huaguo has built a space station, which is not a simple space station, but a place where residents can live.

There is a protective shield on the outside, and humans can live normally inside.

At present, the materials are still transported on the ground, but Su Jiao has opened up several planting areas in the space station, using artificial light for planting, and a batch of vegetables can be harvested in more than two months.

Many botanists and agronomists are working on new projects here, and Su Jiao believes that it will not be long before the space station will be self-sufficient.

Not only plants and crops, but also people raise many animals, and the pond is full of fish that everyone eats, and can meet their daily needs for meat.

Su Jiao took the time to take Qin Shi'an and Qin Shimiao to see it, both of them were very interested in the cultivation of the space station, and Qin Shimiao was even more surprised.

"Mom, we won't have any problems eating the things that grow here, right?" Qin Shimiao asked a question that Qin Shi'an was also concerned about.

"No, there is a protective cover outside, and there is an oxygen concentrator inside, the ecological environment here is similar to the ground, and the protective shield isolates the starry sky radiation, which is safe." Artificial light is safe, and the Coalition has used it for thousands of years without any problems.

"Oh, is it okay for us to come and live on it if we want to in the future?" Qin Shi'an was a little curious.

"Qin Shi'an, do you like to look at such an empty place? It was pitch black outside, and there was no scenery at all. Qin Shimiao muttered quietly.

"Sister, the scenery of Lanxing is very good, but the scenery here is even more special, it's good to stay for a few nights and feel it."

There doesn't seem wrong with thinking like this, it's better than staying in a starship all the time.

Although the eldest uncle made the virtual world out, and he could go inside when he was bored, Qin Shimiao still liked the natural environment and liked to touch the world with his hands.

"Brother, let's go see those fish." After speaking, Qin Shimiao dragged Qin Shi'an away, and Su Jiao followed behind slowly.

The two children are growing up, and there is no place for her to worry about, Qin Shi'an is sensible, Qin Shimiao is ghostly, she is not worried at all that Qin Shimiao will not know the danger and play casually.

Even Qin Shimiao can supervise her brother.

After all, Qin Shimiao was already an adult soul, and he knew what danger was and what he couldn't do.

The two children looked at the fish swimming happily in the pond and had to admire their mother's strength.

In their eyes, building a city in space is something they don't dare to think of!
