When he arrived at the battleship, Stephanie met three United Nations clerks from the United States, Russia and China. The purpose of asking Stephanie to come was also mentioned. In short, it was to let Stephanie use her ability to witness a negotiation - pure business negotiation, but the object of the negotiation was aliens.

Both sides sat down in the reception room, and Zhang Cheng and Stephanie also met aliens. This time was different from the last interrogation. The other party wore a full set of space suits. Although they knew they were smart creatures, humans still felt that they were hideous when they looked at the octopus star.

After the two sides signaled that the talks could begin, they each took out the product catalogs and exchanged them. Zhang Cheng and Stephanie received a product catalog in English and Chinese versions respectively.

After scanning the product catalog, Stephanie said to people from the United States, Russia and China: "The other party's spacesuits have a certain degree of resistance to my abilities, but it can still be done by scanning the psychological dynamics. Now it can be confirmed that the products given by the other party are real, but they are not satisfied with the products given by us."

"I know, if you are not satisfied, you will be satisfied if you are not satisfied."

Zhang Cheng thought the product given by the other party was good, a very prosperous product. In the words of earth, it is a nanorobot.

There are many applications of nanorobots. For example, in medicine, nanorobots can kill cancer cells, crush stones, and remove blood clots.

In agricultural applications, nanorobots can kill parasites and pests on livestock and crops, and can also bring nitrogen and water in the air directly to the roots of crops, and pollination is not a problem.

In life, nanorobots can form anything you need. For example, the octopus astronaut now wears a space suit composed of nanorobots. This space suit will automatically intercept substances that are not good for the body, automatically replace the waste gas inside and fresh air outside, and automatically massage the body's muscles - of course, it also has the effect of a bulletproof vest.

Nano-level people can also form accommodation transportation tools such as houses, cars, planes, ships, etc., computers, insulation water cups and other daily necessities. They can also form hot and cold weapons such as guns, bows and arrows. They are almost omnipotent - in addition to being unable to be digested by gastric juice, they are also harmless when eaten.

However, the greatest value of nanorobots is that they can complete self-replication. That is to say, as long as there is a nanorobot, they can use solar energy as energy to find materials in soil and rocks to create another exactly the same nanorobot. It only takes three or five days for the Earth to complete a replication.

If there are enough nanorobots to form a spacecraft, it is quite simple to fly manned spacecraft. One engine cannot do anti-gravity, but countless engines can do anti-gravity.

After reading the promotional brochure, Zhang Cheng couldn't help but say, "Oh, it's such a good thing."

As a result, Zhang Chengyi spoke, and the aliens on the opposite side also spoke, and they used Chinese: "You are an immortal, right?"

Zhang Cheng was surprised: "How did you know?"

The alien pointed to his head with his tentacles wearing a space suit: "The nanorobots here can detect the intensity of the magnetic field. Your magnetic field strength is at the level of immortals..."

"This is the first time I heard of this statement."

While still talking, internal strife broke out inside the earth first, and Russia couldn't help but say: "There has never been any saviors, nor ghosts and gods."

The US representative said I just check it out and didn't say anything. The Chinese representative followed the Russian representative and nodded in agreement. Although the person on the other side looked like a Chinese, he naturally agreed with what the Russian representative said in terms of values.

"You believe the lyrics too. Dear, have you seen a tiger without a tail and a tiger without an ear running together..." Zhang Cheng felt that he could only show his hands at this time, but how can he use to show his hands?

Zhang Cheng looked around and found that this closed environment was more suitable for simple and easy-to-understand magic, so Zhang Cheng concentrated the fairy energy in his body at a point on his index finger, and saw the whole finger unconsciously emit a dazzling light. Then Zhang Cheng used this glowing index finger to point the porcelain cup containing coffee in front of him.

After Zhang Cheng taped the white porcelain cup, the whole body changed color and turned into a shiny gold color. This is also a trick that Zhang Cheng knew in his previous life. The technique of turning stones into gold - in fact, it consumed a lot. When the master taught, he said that he should play less, but fortunately the cup was not big.

"Villegude." The American representative who looked straight and clapped first - for Americans, it is normal to undermine each other with China and Russia.

Zhang Cheng bounced the cup a few times, then pushed the cup in front of the US representative: "It's golden, I'll give it to you for fun."

"Three grams of oil."

The Russian representative complained in his heart: Isn’t it just a chain reaction that changes the atomic structure?

Of course, it is still difficult to explain how a person can do this scientifically.

The octopus-type alien said at this time: "It's okay, the magnetic field strength on your body has been reduced a lot!"

"No problem, just take a break."

"It's fine." said the octopus: "The immortals always have many drugs, some of which are useful to us. They are unique drugs that cannot be synthesized by machines and can be used as commodities."

In fact, they are all by-products of refining elixirs, and Wushi Powder and Black Gunpowder in the reverse textbook are all by-products.

Now Zhang Cheng probably knows that it is completely impossible to live forever by taking a few pills. Even if this pill exists theoretically, the energy contained in it is enough to burn a person to ashes - from the inside out.

"Look at this." Zhang Cheng didn't have many medicines, but there were still some. He threw out a few porcelain bottles out of thin air, high-level golden sore medicine, Dali Pills, and Jing Bu Jing Pills all over.

The Octopus Star stretched out three tentacles, took away three bottles, and used the nanorobot space suit outside the tentacles to analyze the effects of the drugs in the three bottles and then said to Zhang Cheng: "These two are very useful to us. These are gene repairers and gene enhancers."

Zhang Cheng looked at the gene repair agent that the octopus mentioned was a high-level golden sore medicine, and the gene reinforcement was a pill of Bujing. Originally, Zhang Cheng was still looking forward to Dali Pills...

What Zhang Cheng is more concerned about is: "How many nanorobots can be replaced."

The Octopus Star poses tentacles: "This is not enough to change one. Nanobots are products and technology. Your gene patchers and gene enhancers are complete commodities, and we cannot synthesize even if the ingredients are measured."

Thinking about it, this is the reason. Zhang Cheng waved his hand and had a bunch of bottles on the table. This time he simply took out all the advanced golden sore medicines and essence-enhancing pills: "All of them are here, what about these? How many nanorobots can be replaced?"
