Nanobots

"Have you been following the routines that I have given you? Such as controlling your Qi, reading the books I gave you, and using your Power, such as your Nanobots?" Yuki asked in a gentle voice as she waited for her to answer. When she first read that Fumiko could use Nanobots, she didn't know what to feel because in her mind Nanobots are one of the hardest to control, based on her experience. Back on Earth, she has made a few projects containing Nanobots that change the World, such as having a small metal cube that is about the size of a baby's fist and transform into a perfectly drivable car. Guns that can be hidden as a ring without anyone knowing, a skyscraper that is practically invincible from earthquakes, and fire and safe if it ever gets destroyed because it has a mechanism where all of it would slowly dismantle while still handling everyone who was inside gently. Though the Skyscraper that was made purely with Nanobots was Yuki's hardest project to ever make, it took her at least five months to build it as the main problem was the mechanism, A.I, and coding for the Nanobots so that they knew what to do.

It was even Yuki's finest works that made her recognizable around the whole globe, no one such as herself could think of such a thing, it was unique in its way, but also very helpful for the country especially in Japan. It now doesn't have any buildings that weren't made by Nanobots except for those traditional houses that don't want to be turned into a robotic house that has their mind. Japan has improved so much because of it almost in every aspect, as the Nanobots can create any furniture, appliances, and the shape of your house by just encoding it to the heart of the Nanobot. But to say that the job of creating such Nanobots was easy is an overstatement. It was a hell of an experience for Yuki, it gave her many headaches, and hardships to make. The hardest part of making the Nanobots was to control them, as each Nanobot has its made, she needs to create a system that can control thousands or even millions of Nanobots in a single System. That is why she doesn't know what to feel because the Nanobots on Earth were made and proposed by her, but this was different. She doesn't know if it is the same.

She has already calculated the time that passed since she made her Nanobots from the person that made the Nanobot here in the Immortal Realm. She made her Nanobot back when she was just 18, and it was not even close to the years since the Nanobots were made in the Immortal Realm because she doesn't know or even have any clue about how the Nanobots work, she was quite worried for Fumiko's safety. But she still tries her best and gave Fumiko all of the knowledge that she has and teaches her all of it.

But she was not trying to say that Fumiko is far inferior to her, it is just she was worried because Nanobots were quite dangerous things despite being as small as a grain of sand. There was no way of telling when they can go berserk and if that ever happen, the Nanobots would have their mind and do something out of the System's code which could lead to a dangerous situation.

"Yeah, I have read the two books that you gave me, but there is a thing that I am confused about. In the book you said that you need to have a System or a Computer to control each Nanobot, right? But how do I specifically do that? I don't have a computer to control them." Fumiko was abruptly shocked because it seems that Yuki was trying to avoid fighting Yumie, but she still answered honestly.

"If my theory is correct… you can control your Nanobots in two different ways. One is through your emotions because it may act on emotion, I have seen quite a few Elements that act upon their Master's emotions. The second one is of course your mind as it can act as a Computer System that controls them, though you need to have a tough mind and can multitask. Though I am assuming that you can control them in whatever way you want just by using your mind, you don't need to control each Nanobot as that would be practically impossible… splitting your mind into a Million pieces just to control each Nanobot is just absurd." Yuki said with a slight smile on her face, she then encouraged Fumiko to bring out some of her Nanobots on her palm to witness it.

The two seemed to have their world as they ignore everyone around them, they were talking with each other as if there was no one around them. But that didn't change the fact that everyone was speechless to hear what kind of Power does Fumiko control, even if they have no prior knowledge of Nanobot, you don't need to be a genius to understand how powerful it is, a weapon that can transform to anything that you want is powerful.

Yuki and Fumiko continued having their little conversation, but Fumiko has her eyes closed and was seriously trying to bring out her Nanobots whilst listening to Yuki's every word on how to. She is still new to this, but she was personally taught by Yuki to become a great Cultivator. Nothing happened as the second passed, but no one was discouraged and just waited for Fumiko to make a miracle for herself and that was to bring out her Power. But it didn't take long for something to happen… like magic, bits of a black-looking grain of sand came out of her hand and sat on top of her palm, everyone was practically confused and even thought that Fumiko has messed up, but Yuki was the only person who knew that she was successful in bringing out her Nanobots.

"Looks like your hard work has paid off, you made it… Nanobots. Can you try to change its shape? You can do it with anything you want. But I would suggest something small such as a dagger." Yuki gave Fumiko another task, but this was a lot harder than the first one as this would set how she can control the Nanobot. Fumiko slowly nods her head as she closes her eyes once again to fully focus herself, she uses her mind and began to think of a picture of a dagger and from Yuki's teaching she needs to have as much as detail she can. From the height, weight, length, and width. It was perfectly accurate in what she wanted. It was not a hard thing to do, but she would just need to entirely focus on her job. And as she focuses, Yuki looked at the people beside her and said something.

"Consider this as free training for your mind. Don't try to look down on what Fumiko is currently doing because it is not as weak as you think. Because if you do, you will easily lose against someone. This is also to train your mind to be stronger, to make it adapt to harsh work such as multitasking which is the hardest. And if you can somehow do it, it would look something like this…" Yuki showed them a great example which was making three Ice Fairy that begins to fly around, then each one of them hold a tiny dagger and begin to spar.

"This is it… It might not seem like it, but I am controlling all three of them. Up, down, left, right, forward, backward, and strike." At every command, all three Fairy followed Yuki's words, though it may seem like she was just commanding them through her voice, it was the opposite of what she is doing. Her mind was split into four, and she can even see what the Ice Fairies were seeing.

"I'M DONE! Can you look at it, Yuki?"
