Ye Heng used money to open the way, and asked all over Cloud City in a daze, but no one had this thing, including the largest arms black market under Cloud City and the surrounding cities.

No one dares to sell enriched uranium, not to mention whether there is a buyer or not, and whether it can escape the blow of the state, the radiation alone is enough for these people to eat a pot, and the shell of enriched uranium must also be packaged with inert metal.

The folk method of purifying uranium ore is the local method, but what they get is only "yellow cake", and these uranium concentrates in the form of diuranate or uranate do not have much value in the hands of ordinary people.

The same is true for Ye Heng, he doesn't have the equipment to continue purifying.

Just when he was at a loss, he was told that several people in the lockdown had enriched uranium in their hands and were looking for buyers.

Ye Heng was a little skeptical about this, he didn't believe that these people had real enriched uranium, unless they were smuggled in, or just ammonia biuranate containing a small amount of uranium-235.

Ye Heng still plans to go to the lockdown city, if he can find the problem, it will be solved, and if he can't find it, he will go abroad to try it.

Those outlaws abroad can do any deal, they only care about money.

But now is not the time to leave, the third aunt is about to have surgery, and he has to communicate with him about many things.

It seems that there is still a long way to go in making robots, Ye Heng just wants to protect himself, after all, the international community is not very stable now.

When the time comes, he will secretly develop robots and build his factory underground into a super-large base, just like the base in those sci-fi blockbusters, and I feel excited when I think about it.

Ye Heng returned to the production line, the mastermind was already making and manufacturing robots, except for the power core, other things could be made, and when the time came, just put the power core directly into it.

So be it for now, when you have time, go to the lockdown, and hope that there will be a harvest by then.

After running around for the past few days, Ye Heng found that he had no protection at all, and any man-made or non-human accident could kill him.

"Mastermind, is there any way to minimize the damage I take, such as fending off swords and guns?"

"You can design a close-fitting garment that can distribute the force evenly, and use high-strength and tough materials that have a strong protective effect on the wearer. ”

Hearing that it could be made, Ye Heng relieved himself and asked him to go to those marginalized people in society without protection, he was still a little scared.

"What materials do you need, and how long does it take to make them?"

"Sir, the materials you bought last time are fine, and it takes 2 hours to make. ”

"Okay, let's make this for me first, and then move on to the robot. ”

Ye Heng waited for two hours, and the mastermind made a pure black costume.

He picked it up and looked at it, how did it look like a reinforced suit in the killing city, except for the head that had no protection, everything else was wrapped up, and it was quite thin.

"Mastermind, what about the head?" Others are not stupid, don't they just cut off their heads when they leak a head?

"Sir, I have my monitor on top of the suit, and when you are in danger, I will control and eject the protection. ”

Ye Heng put on the clothes, then picked up a knife and slashed his arm, except for some oppression, he did not cut the clothes.

He picked up the lighter and burned it on his arm all the time, and he didn't even feel the burning sensation, it seemed that it was really invulnerable.

Then it's no problem, after all, safety comes first, so he dares to do some shady deals.

The mass production of this suit must be a good choice, but the cost is a bit expensive, and it cost a set of manufacturing robots when it was just made, which means that it will be hundreds of thousands of dollars less, and I will talk about it later.

At this moment, Ye Heng's father called.

"Hey. Yezi, the doctor said that the operation is going to be arranged, and you must sign it. ”

"Okay, I'll be right here. "Why do you have to sign it yourself? I don't understand.

Ye Heng drove to the central hospital, and then hurried to the ward.

"Mr. Ye, sign here and we can start the operation. The doctor took a document and handed it to Ye Heng.

There was already the signature of the third aunt on it, and he looked at it and thought it was okay, and then signed his name.

The doctor and nurse pushed the third aunt into the operating room, and Ye Heng and the others sat in the corridor outside, anxious.

The success rate of the operation is only less than 50%, everyone is happy if it succeeds, and he is afraid that Ye Xin will not be able to accept it if it fails, this child is in high school, and if the third aunt dies, it will directly affect her studies.

However, for Ye Xin, the results can only be said to be an accessory now, who told her to have Ye Heng, the elder brother, just like her father, it is better to do better than to be born.

The operation was undoubtedly painful, and a short afternoon passed, and the lights in the operating room changed from red to green.

The attending doctor walked out, he unbuttoned his mask and took off his gloves.

Ye Heng and the others hurriedly greeted them.

"How's the doctor, was the operation successful?"

"Which of you is his immediate family?"

"I, I am. The third uncle replied dryly.

"Yes, the bone marrow transplant is done and it is going well, but this does not mean that there is no problem, this depends on the recovery after the bone marrow replacement, whether there is infection, whether there is a non-fusion reaction, and whether the new bone marrow can make blood normally in the new body. ”

"Then can I go in and see my mother?" Ye Xin asked.

"No, because after the bone marrow is replaced, the immune function of the person is almost zero, and now it is in a sterile environment and cannot be in contact with the outside world. ”

Now we can only wait, there is no other way but this. So except for Ye Heng, his parents planned to stay in the hospital and wait, Ye Heng had something to go.

Ye Heng left the hospital and drove back to the factory.

took out his mobile phone and dialed the "intermediary" of the person who said that there was news of the lockdown.

Ye Heng's phone calls are all specially encrypted by the main brain, and they will not be monitored by others.

"Hey, who?"

"I'm the one who asked you about enriched uranium this morning, how did you get in touch with that person in lockdown?"

"Oh, when you get to the lockdown, wait at the entrance of the East Railway Station, someone will come looking for you, remember to tie a purple cloth strap around your arm. ”

Ye Heng hung up the phone, all he thought, how could the group of people in the lockdown look so much like an underworld group?

Ye Heng is now invulnerable, but if others directly kidnap and imprison him, isn't it the same effect?

"Mastermind, check the information about the lockdown of the East Railway Station and the related purple cloth belt. ”

"Yes sir. ”

The so-called knowing oneself and knowing the other is invincible, let the master brain investigate first and make a decision.
