When the third child heard this, his face turned red and he nodded in agreement.

The little goldfish and the others cheered and joked with smiles, but the third child waved their hands in disgust, telling them to shut up.

Seeing them laughing and having fun, Zhou Jimin said again:

"It's like this. I'm going back to the capital in the afternoon and will come back in two days. You guys, the third and fourth, will watch them these two days..."

"Okay, brother, don't worry."

It’s not the first time anyway, so Zhou Jimin is of course relieved.

In the afternoon, Zhou Jimin left the small town of *** and stayed in the capital for two days.

The current situation of the little fat pig has improved slightly, but it is limited.

At just over a year old, he still needs help to walk. He is slightly trembling and stumbling, making him much worse than his older brothers and sisters.

Zhou Jimin checked the little guy as usual and confirmed that there was nothing wrong with his body, which made him feel relieved.

This child is what he and Ding Qiunan worry about the most, and they have put a lot of effort into it.

But he is like a man who understands nine of his ten orifices. He knows nothing, whether it's talking or walking. It's really heartbreaking.

"After he turns two years old, I will feed him space spring water to see if there will be any improvement by then."

Thinking silently in his heart, Zhou Jimin put the matter aside.

He has many children, and his expectation for them is that they grow up healthy and happy.

Regardless of whether it is the child born by Ding Qiunan or the child born by Qin Jingru and the others, he treats them equally.

Only the little fat pig has really worried him from birth to now.

It is said that one looks eighty at the age of three. As far as the current situation of the little fat pig is concerned, if it does not return to normal before the age of three, Zhou Jimin will really be in a hurry.

Among infants and young children born all over the world, there are always some children who are infected with some strange diseases.

Although the little fat pig looks very healthy, from the current point of view, he should have some so-called hidden diseases.

Alas!

After staying in the capital for two days, Zhou Jimin returned to the small town of *** and continued his recklessness.

The engine is still in the wind tunnel laboratory, and there is currently no way to conduct further research, so let’s tinker with the missile propulsion system.

This time, he did not use new materials.

Baiyi alloy material is too expensive, and he doesn't dare to use it on missiles.

Besides, it may not be appropriate.

Intercontinental missiles, also known as ballistic missiles, usually consist of a propulsion system, a warhead, a missile body structure and a guidance system.

At present, there are no other types of intercontinental missiles. There is only one type, and that is the land-based intercontinental missile.

The research and development of land-based intercontinental missile propulsion systems has actually involved rocket launch thrusters.

After all, the fastest speed of future intercontinental missiles is Mach 27.

At present, the fastest speeds of the intercontinental missiles of the two countries, Polar Bear and Bald Eagle, exceed Mach 20.

However, in fact, it is useless to be fast because it is too restrictive.

Moreover, the precision strike error is very large, usually around 2.5 kilometers to 5 kilometers, which is a huge deviation.

Of course, even if the deviation is large, the nuclear warhead of an intercontinental missile is quite powerful.

Due to the reference materials, when Zhou Jimin participated in this project, he proposed that the power of missiles should not be improved simply by relying on large yields, but that precision strike, maneuverability, miniaturization and other aspects should be considered for research and development.

Especially for the guidance system, advanced technologies such as starlight guidance and radar guidance should be developed, and a fast-burning engine can be developed to enable the missile to automatically shut down and fly at an altitude of 80 kilometers.

Spray anti-laser materials or other protective materials on the surface of the missile to improve its own protection capabilities, etc.

These ideas he put forward were unanimously praised by experts from the entire project team.

After all, precision strike and maneuverability are what are most needed on the battlefield.

If the current land-based missiles of Polar Bear and Bald Eagle are discovered by satellites, then an intercontinental missile will pass by and the entire missile launch base will be useless.

However, vehicle-mounted intercontinental missiles with ultra-high maneuverability are not afraid of these at all. Coupled with precision strike capabilities, this is the enemy's nightmare.

Since the establishment of the project, the overall project progress has been quite fast.

The town of Liuer is also involved. After all, the guidance system still requires their participation.

Zhou Jimin is responsible for the fast-burning engines and other missile propulsion systems in the propulsion system.

At present, it can be said that there is no progress at all on Zhou Jimin's side.

He put the fast-burning engine last. What he needs to deal with now is the rocket engine.

The rocket and satellite developed by *** Xiaocheng can only reach Mach 17 in speed. They are just copied and improved. It is useless as a missile propulsion system.

First, rockets and satellites are still too big, and their launch and take-off propulsion weights are in the 100-ton level.

The weight of vehicle-mounted missiles is generally less than 100 tons, and more often 40 or 50 tons.

In other words, its propulsion system will be more advanced, the speed will be faster, and the fuel used for propulsion will be lighter.

The propulsion system can't already weigh 70 or 80 tons, leaving the other warheads with only 20 tons in weight for the missile structure and guidance system, right?

Even so, such a missile is quite bloated, and the requirements for a mobile vehicle carrying the missile will be very high.

After all, generally speaking, the load capacity of large trucks is about ten tons. If a super-heavy truck transporting 100 tons is transported, the fuel consumption per kilometer will be very alarming.

As for vehicle-mounted missiles, maneuverability is more important, so while ensuring the power of the missile, try to reduce the weight of the missile itself. Only in this way can its maneuverability be guaranteed.

A few days later, the wind tunnel laboratory was completed and Zhou Jimin began to inspect the engine.

The improved high-speed ramjet engine made of new Baiyi alloy materials has no problems at all.

The testing in the indoor wind tunnel laboratory has been completed, and the next step is the outdoor wind tunnel laboratory.

All steps must be carried out strictly according to the plan, and no step can be missed.

Zhou Jimin still cherishes his life. Although he has space, it is almost difficult to encounter danger.

But who knows?

Things like rebirth have happened, how can he guarantee that no accident will happen?

His life is his own, not someone else's.

"Dad, is there anything happy that happened? Do you want to share it with us?"

While the laboratory was conducting tests, Zhou Jimin walked out of the study and went outside to relax.

During the recent period, except for the two days he spent in the capital, the rest of the time he was in constant motion, almost never stopping.

I finally went for a walk today. The children happened to be playing in the yard on the weekend.

When they saw their father strolling around with a smile, they all came over and surrounded him.

"Well, Dad did encounter something happy, because Dad solved a big problem..."

The little kids didn't ask any questions, just chattering and pulling him to play games together.

Compared to the capital, there are many more games they can play here in the small town.

Especially those toys at home, every time they invite their friends to play at home, they always get the exclamations from their friends.

In exchange for these toys, they have some foreign friends who invite them to play some games that they know how to play.

There are many different ways to play, such as singing children's songs, playing counting games, card games, catching singles and not catching evens, etc.

After playing with the little kids for more than an hour, Zhou Jimin left home and went to the satellite communications office.

"Xiao Yan, isn't Lao Zeng here?"

Here in the Communications Department, Yan Ziyue was busy with his head down. When he heard the sound of ticking coming from the door, he didn't even look up.

It wasn't until Zhou Jimin's voice sounded that he saw it was Zhou Jimin.

"Hello, Boss Panda, it's like this. Director Zeng is at the research institute, not here."

Yan Ziyue quickly stood up and said respectfully.

"It's okay, is Lao Dong in there?"

"Yes, Team Leader Dong is in the office inside."

"Okay, you go ahead and do your work, I can just go there by myself."

Zhou Jimin nodded and said nothing more to the other party.

After all, his identity is different. An ordinary researcher like Yan Ziyue will still be somewhat nervous when facing him.

Coming to the office inside, Zhou Jimin briefed Dong Chuanan.

The latter is the project team leader of the Satellite Communications Division, and is one of the leaders of the entire Communications Division, except for Zeng Qingfeng and a few others.

Naturally, I came to see this person today not to chat, but to ask about the satellite communication system.

According to Dong Chuanan, the seven satellites in space are currently operating well. From previous tests, they can basically communicate across the country.
