Yu Nan's satellite has a radar wave stealth effect, but also has a counterattack system and a self-destruction system, the largest geostationary orbit satellite weighs only a few hundred kilograms, using the old-fashioned Ark system energy body as the engine energy, for Yu Nan, this kind of thing as long as it can maintain the satellite function.

After working for most of the night and traveling tens of millions of kilometers, Yu Nan finally debugged all the satellites, and when all the satellites began to operate online, this Skynet system, which belonged to him alone, began to comprehensively monitor the situation of tens of millions of kilometers of the earth and outer space.

Piloting the spacecraft back to Earth is another special test for Yunan, regardless of the size of the spacecraft, how to not produce violent friction in the air when it comes into contact with the atmosphere is a top-notch technology.

In some movies, alien spacecraft have to ignite a raging flame when entering the atmosphere, which is impossible, and with the action of anti-gravity systems and thrusters, it does not take much energy to reduce the speed of the spacecraft to the point where it will break through the atmosphere without high temperature friction.

Yu Nan's small spacecraft is testing this technology when it enters the atmosphere, and if the verification is successful, Yu Nan can also use anti-gravity and thrusters combined with low speed to break through the atmosphere and enter space in the future.

Can cancel the gravitational pull of the planet, you can control the speed of the spacecraft, when Yu Nan's small spaceship approached the gravitational circle, turned on the anti-gravity system, as the spacecraft entered the atmosphere vertically at a speed of 100 meters per second, and finally slowly landed on the roof of the villa, Yu Nan came out of the spaceship to check it and happily put away all the facilities.

The test results were flawless, which means that in the future, when Yunan rebuilds the spacecraft, the acceleration of the protruding atmosphere can be ignored, and in the case of gravity cancellation, even if the spacecraft moves like a snail, it can go into space.

......

Three days later, late at night, on the big bunk in the master bedroom of Yu Nan's villa, Natasha had already said goodbye, and Yu Nan had to hold back the anger that he hadn't seen for three days, he didn't expect that he didn't usually feel it, as long as he was with Natasha in the big shop, his anger was so violent, and even got stronger and stronger.

It is said that Natasha has good physical fitness, flexibility and resistance to blows are far stronger than normal people, it should be said that she will squeeze Yu Nan dry, but in fact, she has been defeated repeatedly, and now she can't bear to beg for mercy.

At dawn, Natasha found that Yu Nan had actually gotten up early in the morning to swim in the pool behind, she wrapped a bath towel and went to the bath and shouted:

"Yu Nan, I forgot to tell you last night, Hammer Industries plans to display their new weapons at the Stark Industries Fair at eight o'clock tonight, and representatives of major arms companies and the military will participate at that time, and Stark's friend Colonel Rhodes snatched a steel suit, but Stark is unwilling to say anything."

Yu Nan had already known these news in advance, he swam to Natasha's feet and looked up, and saw that he almost wanted to pull Natasha into the water to be happy, but he knew that if Natasha didn't rest well during the day, he probably wouldn't be able to play at night, he lay on the edge of the bath and scratched his fingers on Natasha's legs and smiled:

"Hammer Industries has always used Stark Industries as a potential competitor, even if Tony has given up on designing new weapons, the last time I watched Hammer, that guy is not a good bird, everyone be careful;

As for Colonel Rhodes, although I haven't seen it, I heard that Tony and him are very close to wearing a pair of pants, you said that Rod stole his steel suit, do you think there is no identification system and control system in a suit? All this is just Tony's intention to let him take it, or it will blow itself up with a bang, who will get his things. ”

Natasha squatted down and pulled Yu Nan to the edge of the pool and sat down, she gently rubbed Yu Nan's arm and smiled:

"It seems that there are a lot of sober people, and I guess so, it should have something to do with Mr. Stark's body, right?"

Yunan knows everything, he doesn't want to interfere with Tony's heroic behavior, because he doesn't need to interfere with these things, he knows that after tonight, Natasha is expected to disappear for a few days, and he also plans to return to reality to deal with some things first, and then enter here or from other movies, as long as Natasha remembers his relationship with him.

Yu Nan thought for a while and said:

"Something is likely to happen tonight, Natasha, pay attention to Hans Industries."

Yu Nan didn't say much, Natasha wouldn't tell Yu Nan casually about the secret, as a S.H.I.E.L.D. agent, Natasha and Yu Nan have a special relationship, in fact, it has a great impact, but how can Natasha withstand the powerful attraction of Yu Nan's four spirit bodies, although she still maintains the sobriety of the agent, her body has completely fallen into Yu Nan's hands.

Remind Natasha to pay attention to Hans Industry, Yu Nan doesn't want Natasha to have a little accident, although he did not interfere with the development of this world, but he still understands the butterfly effect, since he appears in this world, it is inevitable that it will have a certain impact.

Dead someone else, Yu Nan won't care, Natasha is his bed partner, and the two of them are very happy to play, in this case, Yu Nan doesn't want Natasha to have a little crisis.

Natasha smiled and went back to the room to change clothes, she was even more seductive and charming in a black tight leather suit, but few people knew that she was a ruthless agent, and said goodbye to Yu Nan, Natasha rushed to the Stark Industrial Building, but Yu Nan leaned against the bath and whispered to herself:

"Ivan. Vanke ...... Top weapons expert, unfortunately he will die at night. ”

Yu Nan only expressed regret and did not think about recovering Ivan, because he is also a top weapons expert, biologist and physicist, and now he can act as a researcher for at least a dozen research projects by himself, plus his super host system and automation system, he does not want to get a large group of people to conduct production design research.

The power of the green dragon of the Four Spirit Body made Yu Nan's originally evolved brain clearer, and he would not feel the slightest confusion even if he was studying a lot of things, which also allowed him to focus on more things in addition to retreat and cultivation.

He relied on himself in just one or two months to fuse all kinds of science and technology in his hands to make a spaceship, although it can only be a spaceship in the star system, but it means that his technical control and combination ability is no less than a super-large research group, and the manufacturing technology is at the forefront of the world.

With such ability, Yu Nan had no intention of looking for some technicians to assist in the research. A top weapons expert like Vanke would die, and he just sighed for a second and gave up.
