According to Sofia's account, his team entered another core city while exploring other areas of the ruins.

And that core city also happens to have a survivor base.

Originally, everyone was survivor after the disaster and should help each other to build a new home on this ruin.

But the problem is that human nature is restless. Even in the end of the world, no matter how difficult the environment is, internal struggle will never stop.

So, the war began and the survivor bases of the two core cities fought.

Sophia, who has experienced war and betrayal baptism, has long been mature in her mind, and her ruthlessness and coldness are also engraved in her heart. Since the other party wants to fight, then accompany them to fight and fight to the death until the other party is killed.

The battle lasted for more than a year, many people were killed and injured on both sides, and the ruined medical system was almost collapsed. After Sofia used up the collected medicines, she had to ask Jiang Bo for help.

This is not a problem for Jiang Bo.

Long ago, he asked Zhuang Miao to prepare food and medicines in the frozen warehouse. Now Sofia mentioned that he could easily take out the medicines she needed.

When Sofia asked for the drug to be traded, a prompt popped up in front of Jiang Bo's eyes.

[Sophia officially requested you for a transaction. There are three transaction contents, but you can only choose one of them]

【Option 1:1 kg of copperene, option 2: anti-gravity spacecraft wreckage, option 3: The stunning maid from the ruins】

[Please continue to communicate with Sofia based on your thoughts.]

"Copperne?" Seeing the option 1 given by the system, Jiang Bo showed doubt.

Close the pop-up window, Jiang Bo's eyes turned to Sofia and said slowly: "The medicine is fine, but I can only give you the most primitive one."

Sofia hurriedly said: "Yes, the most primitive medicines are the ones that you traded with you a few years ago. If you give them high-end medicines, we can't use them..."

Advanced medicine? Sorry, I don't have one here.

Jiang Bo laughed in his heart, but he remained calm on the surface and continued to communicate with Sofia: "Can you find such a material like copperene?"

"Copperne?" Sophia was stunned, "Mr. Zhushen, are you referring to the kind of copperne used for cables?"

Cune as cable?

Jiang Bo flashed slightly, and realized something in an instant, and said, "Well... I don't know much about it. I just heard such a name by chance. I'm a little curious about it. If you don't mind, you can introduce it to me."

Sophia blinked her beautiful eyes lightly, but she didn't think there was anything wrong with Jiang Bo's words. Instead, she felt that Mr. Zhu Shen was so polite.

Sofia hurriedly said: "Mr. Zhushen, I don't know much about copperene, but I just know some uses. It is a material with strong electrical conductivity. Its most widely used is probably used as a cable."

“Very strong conductivity?”

"Yes, I remember writing in the textbook that the conductivity of copperene seems to be more than 10,000 times that of copper metal."

"That's really an interesting material." Jiang Bo was ecstatic when he heard this. Is this missing something? The system father really loves me, and he likes this routine of playing cards according to common sense.

But Jiang Bo's expression was still calm, "This way, give me 1 kilogram of copperene for this transaction, and I will prepare all the medicines you need in the future."

The light flashed in Sophia's beautiful gray eyes, "Mr. Zhu Shen, do you only have 1 kilogram of copperene?"

"That's right, it's only 1 kilogram." Jiang Bo looked at Sofia with a warm smile on his face. He thought I wanted 1 ton or even more, and the key dog ​​system only gave 1 kilogram a choice.

However, Sofia didn't think so. In her opinion, cable materials such as copperene are objects that can be seen everywhere in ruins and are not of high value.

However, Jiang Bo chose to trade this very ordinary material with her, and only needed 1 kilogram. What does this mean?

Sofia felt it was self-evident.

"Mr. Zhu Shen, I take great care of me. Moreover, he responded to every call from me, and the price offered is within my acceptance range, which means that he must have been paying attention to me... He, he really likes me, right?"

Thinking of this, a thin layer of blush appeared on Sophia's charming and delicate face, and the eyes of Jiang Bo were filled with shyness and shyness.

Jiang Bo did not pay attention to Sofia's expression changes, and all his thoughts were on the top of Tongne and said with a smile: "How about Sofia? You haven't answered my question yet."

"Ah?" Sophia quickly came back to her senses, tidied up the corners of her clothes in panic, stroked her white hair, and tried to remain calm, saying, "No problem, Mr. Zhushen, I can get 1 kilogram of copperene in a short time."

"Very good, then let's do it first. You can prepare copperene now and we will trade it tomorrow." Jiang Bo said.

"Yeah, OK!"

...

The next morning.

Jiang Bo put the medicines into the inventory and came to the ruins again.

However, in just a few minutes, the delivery was completed with Sofia and successfully harvested 1 kilogram of copperene.

Afterwards, Jiang Bo left the ruins and returned to Earth under Sophia's affectionate and shy gaze.

Then he went to He Tianqiang's laboratory without stopping and handed him the copperene he had just obtained.

Through the test, He Tianqiang excitedly told Jiang Bo that this is indeed a material with extremely strong current carrying capacity. The carrier movement speed and carrier concentration have undergone earth-shaking changes compared to ordinary copper metals.

This is an extremely ideal instant charging technology material!

And with it, let alone the instant charging technology, the global power cable industry will undergo disruptive changes.

However, the problem is that this material is strong, but it is only one kilogram, which is too little.

"Professor He, then the task of reverse deriving such materials will be left to you, is that okay?" Jiang Bo said to He Tianqiang.

There is too little material, and the system store does not provide corresponding information purchase options, so we can only let He Tianqiang try reverse derivation first.

"Don't worry, Mr. Jiang, I will do my best to deduce the technology contained in this material." He Tianqiang promised.

To be honest, Jiang Bo actually does not expect He Tianqiang to deduce the entire set of copperene technology in a short period of time.

After all, with examples of nanobionic skins, this kind of reverse deduction technology is often difficult to succeed.

However, what is strange is that Jiang Bo did not report much hope to deduce, but was directly conquered by He Tianqiang two days later.

After asking, Jiang Bo realized that it was He Tianqiang, a genius who suddenly became enlightened and became a great god, but... this tm copper-ene is completely a combination of copper and graphene.

Through detection and analysis, He Tianqiang came up with the composition structure of copperene in less than two hours, and then for the remaining day, he was almost entirely analyzing the composition forms of copper and graphene.

By the afternoon of May 13, I had basically thoroughly studied it, and I also successfully made samples through the single crystal of graphene taken from the carbon material company.
Chapter completed!
