"Do you need to eat?" After Liu Qian sat down on the sofa outside, he took some food and water out of his backpack and asked Yinhe.

"No, I don't." Galaxy shook her head.

"And where does the energy come from when you're physically active?" Liu Qian asked Yinhe a little strangely.

"High-voltage plasma energy supply." Galaxy replied to Liu Qian.

"High-voltage plasma? What's new? "Liu Qian had never heard of it before.

"When you were underground just now, you should have seen those huge magnetic rings, right? It is a very sophisticated magnetic energy generating device that can compress the plasma. Yinhe explained a few words to Liu Qian.

"See." Liu Qian nodded.

"Inside my body, every nanobot is a small plasma reservoir." Yinhe reached out and tapped at the handheld computer in front of Liu Gan, and output the structural simulation of the nanobot in her body to the computer screen.

They all have a spherical device in their bodies, somewhat similar to the magnetic energy array that Liu Qian saw in the underground space before, but the size is much smaller, and then there is an extremely bright light in the center.

"It's a mass of plasma with a high concentration, and its brightness is even dozens of times higher than that of the sun, and I've greatly diminished its brightness on the computer screen." Yinhe continued to explain to Liu Qian.

"How big can nanobots be? Molecular-level, right? How much plasma can be stored in the body? Liu Qian's expression was unclear.

"There aren't many plasmas stored in each nanobot, but when they reach the trillion-trillion-level level, the reserves are considerable. These nanobots are powered by plasma, and at the same time provide my body with metabolic energy. The lightning energy that drained from the sky at the top of the building was compressed by a large magnetic ring array and safely channeled into the small magnetic ring in the nanobot's body and stored. Yinhe explained to Liu Qian in detail.

"It's amazing!" Liu Qian continued to be unconscious.

"I just downloaded part of the database of the main system of the laboratory, and I found all these contents in that database, otherwise I wouldn't know what was going on." Milky Way added a few words.

"How long will the energy stored by the nanobots in your body last for you?" Liu Qian then asked Yinhe, he didn't understand or care about those technical things, and he was most concerned about this issue now.

"Before you wake me up, about seventy-one percent of the nanobots in my body are filled with plasma energy, which is enough energy for me to use for three days without emitting an electric current attack." Galaxy replied to Liu Qian after testing himself.

"Can only be used for three days? That's a short standby time, isn't it? What happens if you run out of energy for nanobots in your body? Liu Qian frowned.

"I'm going to pass out until I recharge those nanobots."

"The lightning rod on the roof of this building is built to recharge your body's batteries? How long did it take to fill this 71 percent? Liu Qian asked Yinhe again.

"According to the records in my database, I was born two months ago, and it took about a month to fill 71% of the nanobots with energy, right?" Yinhe roughly calculated, and then replied to Liu Qian.

"So many thunderbolts in a month to charge so much energy? Only enough for you to use for three days? Liu Qian kept shaking his head.

"The plasma conversion efficiency of the magnetic ring array is very low, and only a few tenths of a thousandth of the lightning that is drained into the building can be converted into storable plasma, and thunderstorms are not every day." Galaxy replied to Liu Qian based on the records in the database.

"In other words, if you run out of energy, I'll have to bring you back here and recharge in the magnetic ring array of the underworld, right?" Liu Qian confirmed to Yinhe, this is a bit troublesome.

"I've just checked, and the magnetic ring array in the ground has been artificially destroyed for some reason, and it is no longer possible to inject plasma energy into the nanobots in my body." Galaxy shook her head.

"Won't you be able to recharge anymore?" Liu Qian is really depressed now.

"Not necessarily, after I find enough parts, I can make a small plasma compression charging device, go to a place with a lightning rod during a thunderstorm, as long as I successfully channel the lightning into this small charging device, I can compress the available plasma into the nanobot in my body and save it." Yinhe took out the small metal box she had found from her backpack, opened it, and explained it to Liu Qian.

The metal box contained some messy parts that Liu Qian didn't even recognize, and they hadn't been assembled yet, and it was obvious that it would be the future lunch box of the galaxy.

"Where are we going to find the parts that are missing?" Liu Qian asked Yinhe.

"According to the information in the main system, the laboratories above the building have the parts I need, and as long as I search this building, I should be able to make this small charging device." Galaxy replied to Liu Qian.

"Oh?" Liu Qian pondered for a while, he might need to readjust his plan, compared to the airship in Qingpu Harbor that he might not be able to get his hands on, it was obviously more important for him to search this mansion and solve the problem of eating at the Milky Way.

The main city can find a way to go over at any time, but once Yinhe faints from hunger, without Jiang Jinyuan, he himself will not be able to wake her up again.

"The conversion efficiency of a small plasma compressor is very low, which can only reach about 0.15 thousandths, and the compression conversion efficiency of the large magnetic ring array underground can reach 0.43 thousandths." Galaxy added a few more words.

"That's too low...... By the way, can ordinary mains power supply charge for you? Liu Qian thought about it and asked the galaxy again, although it is the end of the world here, the motor for gasoline power generation should still be found.

"The voltage is too low to make plasma, at least hundreds of millions of volts." Galaxy shook her head.

"So? Then let's adjust the plan, we won't go to Qingpu Port tomorrow, and we will search the building in one day, and strive to let you make the plasma compressor. Liu Qian thought about it and decided.

"Okay, thank you, master." Milky Way's favorability towards Liu Qian has a slight tendency to increase.

"By the way, what did you just say about the external discharge current attack?" Liu Qian remembered something, so he asked Yinhe again.

PS: In the new week, at the critical moment of the new book list, I ask my brothers and sisters for recommendation votes, thank you!
