This kind of attraction from biological instinct comes from the genetic level, and personal emotions will be affected instead, just like Natasha will take the initiative to go to Yu Nan, which is unlikely in itself, but in fact, Natasha did it, and she didn't even regret it at all, this is that she feels that Yu Nan is the best match at the genetic level, and as a female, her body even has a strong sense of surrender, but this is just the beginning of her ability to let the agent instinctively suppress one or two, as for the future, it is estimated that it will be very suspenseful.

When Natasha seemed a little inconvenient to walk, Yu Nan muttered with a little smugness:

"Supposedly, I shouldn't be so powerful, Natasha is a Russian woman, or a well-trained top agent, her endurance and endurance are far beyond ordinary people, is it a physical problem of my evolution, but with Natasha, don't worry about her accidentally winning the bid, she has been sterilized when she became an agent."

Yu Nan is studying all kinds of medical classics from Tianmen during this time, don't underestimate the guy Emperor Shakti, he has a disciple called a divine doctor, just with medical skills, he can almost live the dead with flesh and bones, and his medical skills are superb, Yu Nan found that he couldn't use scientific and technological means to make himself a normal person for the time being after studying genes, he simply studied the top medical skills in the Fengyun world.

Therefore, his various medical skills have reached an extremely high level, with his genetic level and the combination of ancient medical skills, it is not difficult to restore Natasha's fertility problem, but he has no intention of letting Natasha give birth to a male and half female inheritance for him, so knowing that Natasha is unable to have children, he can do that kind of thing without restraint.

After Natasha left, Yunan got up and went to the basement, opened the compressed space device, and he continued his various researches.

During this time, Yu Nan didn't just stay like this, he didn't have much to worry about doing things, on Natasha and Tony, he released the ultra-miniature spy robot that he had only made recently, and its purpose was very simple, that is, to complete his plan.

There are a lot of scientific and technological products in S.H.I.E.L.D., these are not very much in Yu Nan's eyes, what he cares about is a thing in S.H.I.E.L.D.'s secret research base outside the city.

Cosmic Rubik's Cube, which is an object with powerful space power, or a kind of space energy crystal, one of the six infinity stones of this world legend, can not only have powerful energy, but can even open space and the derivative plane of this universe.

For the derivative plane of this universe, Yu Nan also knows very well, the plane, the universe, this is a spatial structure of interlaced existence, the infinite plane is different from the derivative plane of this universe, the infinite plane can be the existence space of the magic fairy with various scientific and technological special abilities, and the derivative plane of this universe is a superimposed existence, and all spaces have a special cosmic structure with potential connections.

The six infinity stones are one of the powerful energy structures in this universe-derived plane, Yu Nan has the intention of not letting go of the benefits, and has now used a miniature robot to detect the existence of the cosmic Rubik's Cube, but he has not yet found a way to control this energy, he simply responds to all changes and takes the cosmic Rubik's Cube at the right time.

Tony is studying his steel suit at home, and there is a semi-artificial intelligence to assist, theoretically it is difficult for others to enter this semi-artificial intelligence database to seize information, but Yu Nan's super quantum computer group is too fast, and it only took half a second to crack Tony's artificial intelligence database and copy all the relevant information.

Yu Nan is now analyzing and studying the advantages and disadvantages of the steel suit, so as to improve the structure of his sound-absorbing steel suit, and in the continuous research, Yu Nan also admires Tony's genius design, the miniature missile launcher hidden in the shoulder arm, and the use of ion thrusters to excite high-energy ion light wave attacks, which Yu Nan has never thought of.

The steel suit is propelled in the hands and back thrusters, and the concealment is extremely good, but the variable trajectory of the battle is worse, Yu Nan is constantly modifying the design of the sound-absorbing steel suit, he plans to make a new suit with faster dress, stronger attack performance, and an energy shield, only with the ability of sound-absorbing steel to absorb energy, he is not sure that he can eat in other worlds.

In the afternoon, Yu Nan returned to the ground, he drove the helicopter around the beach, and from a distance he saw Natasha's sports car speeding by, and after entering the villa, she stood on the tarmac and waited for Yu Nan to come back.

When Yu Nan turned off the helicopter and jumped, Natasha, who was dressed in a black tights, came over pretty, and the two hugged each other for a while, and the two of them seemed to be eager to start the exploration of life next to the helicopter.

After a period of intense exercise, Natasha and Yunan entangled back to the living room, until it was dark and the sensor light in the house was turned on, and the two slowly separated, and Natasha was already weak and leaned on the sofa and said in a greasy voice:

"Yu Nan, how did I find out that I couldn't help it when I saw you now, and I almost forgot about it."

Yu Nan leaned on her heart and said curiously:

"What's the matter?"

It is said that there should be nothing serious during this time, the news of the Hulk was published in the newspaper, but he has disappeared from people's sight, and S.H.I.E.L.D. has no plans to accept the Hulk into the Avengers, so there is no problem with this matter for the time being;

Tony had just handed over most of Stark Industries to Perper, and he was concentrating on developing a new steel suit at home and looking for a cure for the ailments caused by radiation in his heart. Vanke was rescued from Monaco prison and hired Hammer Industries as the chief weapons designer, and it was impossible for Hammer Industries to create a robot warrior in three or five days.

Therefore, Stark Industries will not have trouble at this time, as for his existence, his personal combat power is strong, and his wealth is extremely amazing, but it will not cause too much tension in S.H.I.E.L.D., not to mention Natasha's relationship with him, Natasha will never give him a negative evaluation, and big things will not happen to him.

In addition, what special things can make Natasha say when she is happy, Yu Nan rubbed Natasha's heart, and after Natasha groaned, she quickly hugged Yu Nan's head and kissed it and said:

"Do you know the Fantastic Four?"

Yu Nan nodded, he knew that the Fantastic Four were in this world, and even lived in New York City, but he didn't have much interest in the Fantastic Four Yu Nan, at least not now, so he just inquired about the news and didn't follow.
