In the evening, Ning Yu finally met the representative of the Matsumoto family, a middle-aged man who felt very serious, and it could be seen from the other party's gorgeous clothes that he was the core figure of the Matsumoto family.

"In Shimomatsumoto Yasu, it is an honor to be able to meet Ning Shao, to be able to occupy the Lai family at such a fast speed, and the Ning family of the three major gene families really deserves its reputation."

Hearing the other party's compliments in Chinese, Ning Yu was a little more curious about the other party's intentions.

"I don't know what happened to Mr. Matsumoto's coming to Ning's house, if it's about that batch of mechas, I can return it now." Ning Yu had already thought about it, compared with the 60 billion deposit, this batch of "anteaters" was not very important.

"No, those mecha are just one of the reasons why I'm here, I have a more important business to discuss with Ning Shao."

Ning Yu knew that the main event was coming, so he nodded and continued to listen to the other party's next words.

"I heard that the Ning family wants to step out of the earth to develop in outer space, so they should urgently need relevant technology and assistance from outer space, but I wonder if the Ning family wants to have an ecological ark in outer space?"

Ecological Ark? Ning Yu quickly looked up this word from his already small number of human space words.

However, Yan Caiyu's expression, who was listening to the side, was very reflective, and she looked surprised.

Thinking about it, Ning Yu finally remembered what the ecological ark was.

Before the outbreak of nuclear war, various countries established a large number of space stations in space, and these space stations gradually evolved to gigantic with the upgrading of technological competition and military demonstrations of various countries.

Of course, this is only from the perspective of human beings, and there are many things in Ning Yu's shattered memories that are larger than human space creations.

However, it is impossible for the Ning family to make those things in Ning Yu's memory now, even the highest technology of human beings cannot build such things.

Looking at it this way, this kind of human space creation is now the best platform for the family to gain a foothold in the universe.

Matsumoto Yasu also saw the possibility of a deal in Ning Yu's eyes, so he smiled and continued: "The inner diameter of the main gravity ring is 10.3 kilometers, the width of the ring is 4.1 kilometers, excluding the outer solar panel array and the airport platform, the average thickness of the gravity ring is 0.8 kilometers, it can dock 8 large capital ships and 32 medium-sized ships at the same time, and it also has an ecological circulation farm and a gas-liquid circulation system that can normally maintain a maximum of 100,000 people......"

With Matsumoto's explanation, a three-dimensional projection was projected from his portable mind, in which Ning Yu saw a huge space station shaped like a wide bracelet, and its huge volume, even if Ning Yu saw it in the projection, he also felt extremely shocked.

The inner diameter of 10.3 kilometers simply makes the capital ships next to it seem small, you must know that the capital ships are generally more than 1.5 kilometers big, which shows the huge size of this space station.

In the projection, Ning Yu also saw that the bracelet-like space station was always rolling. Ning Yu knew that this was to replace gravity with centrifugal force, so that the inner surface of the ring of nearly a hundred square kilometers could have artificial gravity, and this gravity was proportional to the speed of rotation.

This method is the most important method of obtaining gravity in the universe today, because although human beings already know the existence of gravitational waves, in the application of the universe, human beings are not yet able to create gravitational waves by themselves, so the easiest way to obtain gravity is the gravity arm and gravity ring.

This is already known from the "Kangaroo" obtained by the Ning family, because the living module of the "Kangaroo" is a kind of rotating gravity arm.

In addition, the starship program of the Ning family is also developing a gravity device that can transition from the surface environment to the space environment, requiring the ground to adapt to the gravitational field, and quickly enter the centrifugal state after liftoff.

Just now, after Matsumoto Yasu threw this thing, he observed Ning Yu's expression, and saw that Ning Yu was a little moved, so he began to explain in depth.

While Matsumoto Yasushi was explaining, although Ning Yu was looking at the projection in front of him, he was thinking about the Matsumoto family's intentions in his heart, because the other party threw such a thing, and the Ning family had no equal bargaining chips at all.

Ning Yu smiled secretly in his heart, he had never seen the rich man holding the gold ingots to exchange things with the old farmer, didn't this Matsumoto family have a problem with their heads. The Ning family now has a large amount of food and materials in their hands, isn't it just an old farmer...... Hehe...... Hey...... Don't............

Ning Yu finally understood what was going on, the biggest bargaining chip in the Ning family's hands now was food, this Matsumoto family should have used the mecha matter as a cover to fight the Ning family's food abacus, they were afraid that more families would see the source of those foods on the market, so they deliberately made things difficult for the Lai family on the surface, and took the opportunity to contact the Ning family.

Ning Yu roughly calculated, although those grains could not be compared with the other party's conditions now, but once the food crisis spread, this batch of food would become the life-saving food of the major families, and these people had to pay attention to it.

Thinking about whether to point it out in front of the other party, Ning Yu really didn't want to listen to the other party continue to introduce this ark, listening to it was too exciting, Ning Yu was afraid that he would not have the courage to bargain with the other party for a while.

"Does the Matsumoto family want to give this ecological ark to the Ning family?" Ning Yu asked with ill intentions in his heart. At the same time, there was a layman's expression on his face, pretending to be vivid.

"Ah......" Matsumoto Yasu was first startled by Ning Yu's lion mouth, he had never seen such a person, what is this ark, it is a small city with a valuation of no less than 4 trillion earth coins just Ah, I want to give it away for nothing, you must know that 4 trillion can buy more than 30 capital ships.

Fortunately, Matsumoto Yasu is not a simple person, his expression quickly changed back, and he glared at Yan Caiyu who was smiling secretly next to him and said: "We are very sincere, if the deal is reached, we can also give that batch of mecha to you." ”

Seeing that Ning Yu continued to pretend not to know.

Matsumoto Yasu shook his head and said, "Okay, you know that our family usually sends technical advisors to the products that are lent out, and our personnel in the Lai family happened to hear that the Lai family has stored a huge amount of food supplies not long ago......"

Ha, hearing this, Ning Yu can already confirm his inference just now, the Matsumoto family is really here for the food reserves under this base.

"Since Mr. Matsumoto already knows, then I will ask clearly, how much do you want to exchange, I'm not sure that the amount of food we have is enough for your ark?"

After Ning Yu finished speaking, Matsumoto Yasumoto was detained for a moment but did not answer, Ning Yu saw that the other party really didn't know his hole cards, so Ning Yu was finally relieved, he planned to take out half of the food, saying that it was all in his hands, to see if the other party could change it, Ning Yu felt that he really had the potential of a profiteer.
