According to Sophia, 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 a survivor of the disaster, and it was supposed to help each other to build a new home on top of the ruins.

But the problem is that human nature is restless, even in the last days, no matter how difficult the environment is, the infighting will never stop.

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

Sophia, who has experienced the baptism of war and betrayal, has long matured her mind, and ruthlessness and ruthlessness are also engraved in the depths of her heart.

After more than a year of fighting, many people were killed and wounded on both sides, and the ruined medical system was nearly collapsing, which forced Sophia to turn to Jiang Bo for help after she ran out of collected medicines.

This is not a problem for Jiang Bo.

A long time ago, he had asked Zhuang Miao to prepare food and medicine in the freezer, and now Sophia mentioned that he could easily take out the medicine she needed.

When Sophia's request to trade drugs fell, a prompt popped up in front of Jiang Bo's eyes.

[Sophia officially makes a trade request to you, and the transaction content has the following three items, but you can only choose one of them]

[Option 1: 1 kg of cupurene, Option 2: Anti-gravity ship wreckage, Option 3: Stunning maid from the ruins]

[Please continue to communicate with Sophia according to the thoughts in your mind.] 】

"Cufene?" Seeing the option 1 given by the system, Jiang Bo looked puzzled.

Turning off the pop-up window, Jiang Bo's eyes fell on Sophia, and he said slowly: "The medicine is fine, but I can only give you the most primitive kind." ”

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

Sorry, I don't have any of them.

Jiang Bo smiled secretly in his heart, but he remained silent on the surface, and continued to communicate with Sophia: "You can find this material like copperene, right?"

"Curacene?" Sophia was stunned, "Mr. Chasers, do you mean the kind of copper that is used to make cables?"

Copper for cables?

Jiang Bo flickered slightly, realized something in an instant, and said, "Hmm...... I don't know the specifics, but I heard such a name by chance, and I'm a little curious about it, if you don't mind, you can introduce it to me. ”

Sophia's beautiful eyes blinked slightly, but she didn't think there was anything wrong with Jiang Bo's words, but felt that Mr. Chaser was really polite.

Sophia hurriedly said: "Mr. Chase, I don't know much about copperene, but I know some uses, it is a material with strong electrical conductivity, and the most widespread use is probably to use it as a cable." ”

"Very conductive?"

"That's right, I remember writing in the textbook that the electrical conductivity of copper ene seems to be more than 100 to 10,000 times that of copper. ”

"That's really interesting material. When Jiang Bo heard this, he was ecstatic, what is missing from this, right? The system father really loves me, and he likes this kind of routine of playing cards according to common sense.

But the expression on Jiang Bo's face was still calm, "That's it, you give me 1 kilogram of copper in this transaction, and I will prepare the medicine you need when I go back." ”

The light in Sophia's beautiful gray eyes flickered, "Mr. Chaser God, do you only need 1 kilogram of cuperene?"

"That's right, just 1 kilogram. Jiang Bo looked at Sophia with a warm smile on his face. I thought I'd like 1 ton or more, but the key dog system only gives me a 1 kilogram option.

However, Sophia does not think so, in her opinion, copper ene, a cable material, is an item that can be found everywhere in the ruins, and its value is not high.

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

Sophia felt that it was already self-evident.

"Mr. Chaser has taken such good care of me, and he has responded to my every call, and the price he has offered is within my acceptable range, indicating that he must have been paying attention to me all along...... He, he doesn't really like me, does he?"

Thinking of this, a thin layer of blush appeared on Sophia's charming and delicate face, and her gaze at Jiang Bo was full of shyness and shyness.

Jiang Bo didn't pay attention to the change in Sophia's expression, all his thoughts fell on the copper ene, and said with a smile: "How about Sophia? You haven't answered my question yet." ”

"Huh?" Sophia hurriedly came back to her senses, tidied up the corners of her clothes in a panic, brushed her gray hair again, tried to keep her composure, and said, "No problem, Mr. Chase, 1 kilogram of cuperene, I can get it soon." ”

"Very good, then let's do this first, you go and prepare copper now, and we will trade tomorrow. Jiang Bo said.

"Uh-huh, okay!"

......

The next morning.

Jiang Bo put the medicine in his inventory and came to the ruins again.

In just a few minutes, the delivery was completed with Sophia, and 1 kilogram of copper ene was successfully harvested.

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

Then he came to He Tianqiang's laboratory non-stop and handed him the copper ene he had just gotten.

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

This is an ideal material for second charging technology!

And with it, not to mention the second charging technology, the global power cable industry will undergo subversive changes.

It's just that the question is whether this material is strong or not, but it's only one kilogram, which is too little.

"Professor He, the task of reversely deriving this material is left to you, no problem, right?" Jiang Bo said to He Tianqiang.

There are too few materials, and there is no corresponding data purchase option in the system store, so he can only try to reverse deduce it first.

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

To be honest, Jiang Bo actually didn't expect He Tianqiang to be able to deduce the full set of copper enene technologies in a short period of time.

After all, there are examples of nano-bionic skins in the past, and it is often difficult to succeed in this kind of reverse deduction technology.

However, the strange thing is that Jiang Bo did not report much hope for the derivation, but two days later, it was directly conquered by He Tianqiang.

After asking, Jiang Bo found out that it was not He Tianqiang's genius who suddenly became enlightened and became a great god, but ...... This TM copper ene is completely a combination of copper and graphene.

Through testing and analysis, He Tianqiang obtained the composition and structure of copper ene in less than two hours, and then spent more than a day analyzing the composition of copper and graphene.

By the afternoon of May 13th, it was basically thoroughly studied, and a sample was successfully made through the graphene single crystal taken from the carbon company.
