After submitting the system, Tongzi and I became famous all over the world

"Don't worry, they won't come here again. By the way, this is Murong Yan, the secretary of the chief of our base. He came here specifically to trade technology with you. This is Minister Hua Zhao of the Ministry of Foreign Affairs and Mr. Yan from the Research Institute."

After Han Chen finished speaking, he pointed at the two people next to him and introduced them. He and Lao Zhou already knew each other the last time they came here, so there was no need to introduce them again, so he only introduced the few people who came this time separately.

"Hello, hello, please come in and sit down. Don't stand outside."

After saying this, Luosangsang quickly led everyone into the store's rest area, and Chen Yanxuan also smartly poured a few cups of tea over.

Although I don't know the origins of these people, but looking at the expressions of my two teammates, I guess these people who came this time must be big shots, so I'd better listen carefully.

"Hello, I heard about your request last time and we discussed it for a long time. We also brought technology with us this time. The technology before the apocalypse can be traded at the price we agreed on last time, but for the technology after the apocalypse, we still want to renegotiate the price. I would like to tell you the details."

After sitting down, Murong Yan began to speak. Although the price of this transaction was not low, the weapons developed after the end of the world, the use of crystal cores, and the potions that stimulated superpowers were all very precious. If they were not from this world, they would not have taken them out for trading.

After all, it is safest for these technologies to be in the hands of their own country. If they are scattered abroad, they do not want another base to appear in the world to compete with them. The world is already in chaos, and it will become even more chaotic if that happens.

Luosangsang glanced at Lu Chenyu beside him, and the two looked at each other without saying anything. He did not expect them to make such a request, but he also wanted to first understand what technology they were going to trade this time.

"Can we know what post-apocalyptic technology you want to trade?"

"Sure, thank you for your help, Mr. Yan." After saying this, Murong Yan looked at the old man beside him.

The old man next to him slowly put down the teacup in his hand and said.

"I haven't felt so comfortable in a long time. This tea is really good. Kids, do you have this tea for sale? Pack some for me so I can take it home and drink it slowly."

"Yes, Mr. Yan. I will send you some later. I will give you a pack of each type of tea. You can take them back and drink them slowly." Luosangsang replied with a smile.

"Okay, okay, then this old man will thank you first." Old Yan laughed and continued.

"I heard that you wanted to exchange for technical data, so I came here to take a look. You are all good children. You are exchanging these for your country. I won't talk about the things before the end of the world. I have already prepared everything for you, including weapons, industry, lithography machines, medicines, etc. But I will tell you about the things after the end of the world."

"Since the end of the world, cold weapons and pistols can no longer do any harm to zombies, so we are now researching laser guns and pulse guns, and the main energy source used by these is the crystal core."

"In addition to weapons, there is also a supernatural power activation potion, which we also extracted from the crystal core. Moreover, people who take the potion can greatly enhance the activation of supernatural powers. Of course, the success rate is only about 40%."

"We also have testing equipment that will test what type of superpowers you are suitable for before activating your superpowers. This way, after the test, taking the medicine to activate your superpowers can increase the success rate of superpower activation, and..."

Listening to Old Yan's slow narration, Luosangsang's eyes lit up, and he tugged at the corner of Lu Chenyu's clothes without making a sound. Chen Yanxuan next to him was also ecstatic when he heard it.

"That's all we have for now, so we want to renegotiate the price of the technology. We hope that after the end of the world, the price can be raised to 80 each. If that's possible, we can trade now."

After saying this, Mr. Yan stopped talking and picked up the teacup on the table and continued drinking.

After a moment of silence, Lu Chenyu spoke up. "Can we discuss this first?"

"can."

Hearing this, Lu Chenyu pulled Luo Sangsang and Chen Yanxuan to the cashier counter and asked softly.

"What do you think?"

"I think it's possible. After all, even if we take the crystal core back now, our researchers can't research anything right away, and they certainly can't research as much as they have. Moreover, I just heard from Elder Yan that there is also a superpower activation potion. Although the success rate is only 40%, if this technology is exchanged, the cost of creating superpowers in the future will not be so high for the country."

Luosangsang said that she really thought it was feasible. Although the price had increased by 30 trading coins, she felt that it was worth the money because it could help the country avoid some detours when researching these things.

Chen Yanxuan on the side also nodded in agreement.

Seeing that both of them had expressions of agreement, Lu Chenyu nodded to indicate that he understood, then walked back to the rest area and looked at the people opposite him.

"Okay, then it's settled. The post-apocalyptic technical data will be 80 trading coins each, and everything else remains the same."

"Okay, Xiao Han, take out all the information and give it to the kids." After hearing their agreement, Mr. Yan was very happy, and then turned to look at Han Chen and said.

"Okay! Mr. Yan."

Han Chen responded, then waved his hand and took out all the information he brought this time from the space. Sheets of paper were piled together, forming three large piles. There were also several large bags of crystal cores in sacks, which were densely packed together, which was quite spectacular.

The hearts of the three people watching trembled together, and they kept sighing in their hearts, it really is worthy of being an official base, you can tell whether it is good or not as soon as you make a move, it is too arrogant, they like this arrogant look so much~

"They are all here. There are eight copies of technical data before the apocalypse and five copies after the apocalypse. This time I also brought crystal cores from the base and exchanged them together."

After Han Chen finished speaking, he lifted up several bags of crystal cores together with the guards beside him and poured them into the exchanger. For a moment, the store was so quiet that the only sound could be heard was the clattering of crystal cores hitting the cabinet.

This pleasant sound made Luosangsang and the other two feel excited. These are all treasures...

This sound continued for several minutes. After everything was poured in, the exchanger also gave the specific transaction currency.

[Level 5000 crystal core, level crystal core, level crystal core , level crystal core...total exchangeable trading coins.]

"Wow~"

Chen Yanxuan couldn't help but exclaimed. This was the first time he had seen so many crystal cores. Not to mention him, even Luosangsang and the others looked at the transaction figures. It was more than 1.2 million. It was really amazing! Just the crystal cores could be exchanged for so many trading coins.

Even after being surprised, he did not forget to ask Xiaobai to exchange the technical information for trading coins.

After being busy for a long while, she finally finished trading all the items from the two official bases. As the quantity of this transaction was too large, covering everything from food, clothing, and medicine, she not only exchanged all the items in the warehouse, but that was not enough, so she bought some more from the system store.

By the way, I also packed several bags of the best tea for Mr. Yan, which made the old man so happy that he narrowed his eyes.

After exchanging the money and chatting for a while, they prepared to go back, but this time they left two armies behind, and it seemed that they were going to station near the store.
