To put it bluntly, this printer can't print nanorobots with complex structures.

But directly use this printer to print according to the basic structure of graphene, you can print the most perfect graphene crystals, but its output will not be very high.

"Modeling is complete, start printing."

Gu Qian completed the modeling of the core components of the graphene preparation production line and began to print directly, and with a slight sound, it didn't take long for Gu Qian to get a core component.

"Next, we will wait for all kinds of equipment to arrive and assemble the production line."

“……”

In the evening, Gu Qian returned home, and after dinner, he returned to the room to burn incense for the system.

"Erha, the soul is back, ......"

"Erha, the soul is back, ......"

"Host, I'm coming......"

Xiao Erha appeared in Gu Qian's sea of consciousness in a hurry, and it wagged its tail desperately trying to rub against Gu Qian.

"What are you doing?"

Gu Qian looked at its appearance and couldn't help but push it out.

Who knew that Erha looked aggrieved, and it cried with tears in its face.

"Host, it's not fair."

"What's wrong?"

Gu Qian looked at it suspiciously, wondering in his heart if his own system was being bullied in the underworld again?

Erha:(¬_¬)

Xiao Erha glanced at Gu Qian, and then said quietly.

"Host, the hostess of other people's houses holds their pets in their arms and massages them with big breasts."

"Why don't you do that, it's not fair."

"I'm going to kill with a big chest and a stuffy face, ......"

(*'dish ́*)ノ┬─┬ノ┻━┻

Hold a grass!

Gu Qianqi grabbed it and beat it up, this system dared to go to the house to expose the tiles without fighting for three days, and he had no memory at all.

Fat beat the system, and didn't care about it crying dad and calling mother, Gu Qian threw it aside, and then he thought of business.

"Hurry up and ask you something."

"I can't get up, anyway, I'm already a waste Erha, no one hurts and no one wants it."

The system was lying on the ground and rolling, looking like a waste of wood.

"When others see the pets of beautiful women, they are envious and jealous, and they want to replace them, and I guess that even single dogs will despise me."

"Woo woo, I'm already injured, I need my little sister to kiss and hug me to get up."

"I want the host's stuffy chest to kill, ......"

"Hehe......"

Equity had a black face and couldn't help but sneer.

"If you don't get up again, don't expect me to burn you for a while."

"Aha, don't host, if you have something to say, I'm kidding."

Hearing Gu Qian say this, Erha shook his body and got up, and came back to life with full blood in a second.

God, the reason why it can live a good life in the underworld is because Gu Qian burned a large sum of money for it every once in a while.

If Gu Qian gave it no food, then it would be back before liberation and would have to sleep in the bridge hole.

"Host, what do you want to say, Xiao Erha, I know everything, and I have no end to it."

"You know each other."

Gu Qian sneered, and then said with a straight face.

"You can help me see how much power is needed for controlled nuclear fusion technology."

"Wait a minute, host." Xiao Erha was silent for a while, and then said: "There are many kinds of controlled nuclear fusion technologies. ”

"These include large-scale thermonuclear fusion technology, small-scale thermonuclear fusion technology, micro-thermonuclear fusion technology. It is also necessary to subdivide magnetic confinement controllable nuclear fusion, inertial confinement controllable nuclear fusion ......"

"In each of these categories, the heart of science and technology has documented seventeen ways to achieve controlled nuclear fusion."

Hearing the system say this, Gu Qian nodded, which was expected.

"Help me choose the one that is the best at the price and the easiest to achieve."

"Okay." Xiao Erha lowered his head and answered, and then said: "The easiest and cheapest magnetic confinement large-scale controllable nuclear fusion technology requires six million power points. ”

However, it added: "However, its pre-technology magnetic confinement technology and superconducting material technology cannot be realized at the current scientific level." ”

"Is that so?"

Gu Qian had thought of this a long time ago, this was like giving a primitive man a cannon, and the primitive man who couldn't master the cast iron technology couldn't make a cannon at all.

In the same way, modern people who do not have enough magnetic confinement and superconducting technology will not be able to achieve controllable nuclear fusion even if they draw a scoop from a gourd.

"Help me see magnetic confinement techniques for controlled nuclear fusion, and superconductivity techniques."

Gu Qian said and added another sentence.

"Also, help me see accelerators for controlled nuclear fusion."

"Okay, host, wait a minute."

Xiao Erha said and began to look for related technologies.

"There are four magnetic confinement technologies that can satisfy controlled nuclear fusion."

"Among them, the most suitable price and the best effect is "Advanced Electromagnetic Technology", which can confine plasma well."

"The accelerator can use the super particle accelerator of "Heart of Technology", which can make deuterium and tritium nuclei collide at extremely high speeds, instantly producing a high temperature of 200 million degrees."

"Well, not bad." Gu Qian nodded, most of this problem has been solved, it depends on the material.

"Help me look at superconducting metals."

"Okay." Xiao Erha nodded and bared his teeth.

"Host, there's a magic alloy that's particularly suitable for controlled nuclear fusion."

Soon, from Erha's mouth, Gu Qian figured out the role of this superconducting alloy.

The name of this alloy is superconducting alloy A, and its performance is far beyond the imagination of many modern people.

First of all, when the temperature exceeds 20 degrees Celsius, the resistance of this alloy will become zero.

When the temperature exceeds 6,000 degrees, it will be transformed into a semi-energetic and semi-material form, and its microstructure will undergo a fundamental change, and at this time, its thermal resistance will magically become zero.

"That's an exaggeration, isn't it?"

Gu Qian was a little surprised, as we all know, the higher the temperature of the metal, the higher its resistance and thermal resistance will become, and once it reaches a certain temperature, it will burn out the metal.

And this superconducting A alloy actually has a lower resistance and thermal resistance at higher temperatures, which completely violates the laws of physics.

"Host, that's not an exaggeration."

Xiao Erha shook his head: "In fact, if you follow the theories of the real world, many theories can't make human beings go far. ”

"Even many theories have been proven wrong, so if humanity wants to step into the interstellar age, it must establish new theories."

"And this superalloy itself is the product of a new theory."

“……”

Gu Qian was speechless for a while: "Okay, okay, Ren Tianya is the author of the heart of science and technology, and he can open his brain as he wants." ”

"But you've got to make sure it works in the real world?"

"There's something really wrong with that."

Erha said, leaning its head away, as if thinking about something:

"He's not a scientist after all, so the superalloy technology in the book can't be copied into reality."

"However, the system can use his ideas to deduce superconducting A-alloy technology and theories that are suitable for the rules of this world."
