"Why is this so big?" Leon asked. "I just want to read some archives... I don't want to make calculus and discover how to use them all the energy of the sun."

"You asked for the best compute, that is the best we currently have," Yuki said. "With it, you can make simulations of many things. Though, I doubt that you know how to use it. Anyway, you will find all the information you are looking for inside of it. There are also tons of images that you can use as a reference. I don't know how you can transform a small amount of earth into sunglasses, but you will need that kind of extra information for whatever you are trying to do."

"Thanks. How much do I owe you?" Leon asked.

"You can have it for free since you helped us a lot more than once," Yuki said. "That is what I would like to say... but we are quite interested in your helmet. You said with it you can increase your aim and also have several other functions. If you are fine with it, we would like to study and try to replicate."

"It will be difficult since that is alien technology, but I guess it is fine," Leon said. "But if you succeed in replicating it, you will have to negotiate them with the other camps."

"That is only fair," Yuki received the helmet. "I will try not to rip them off... too much."

Leon sighed. Regardless, he wouldn't need that helmet for the time being, probably. And considering everything, it would be safer and more convenient to install it and study on Ilyana's world.

"Ilyana, can you transport me and this computer back to your world?" Leon asked.

Yuki and Ren frowned when they heard Leon saying that, they didn't know any Ilyana. So, they couldn't help but frown since no one was near them. To make matters worse, Leon waited for an answer for several minutes.

"I know that you are watching me, don't pretend and try to make a fool out of me," Leon said.

Once again, no answer. Leon was getting kind of angry since it was evident that she was trying to mess with him, but two people can play that kind of game.

"You don't transport me and this computer now. I will learn Thoughtography and distribute the picture of how you looked on the first time I saw you to all the people on the planet," Leon smirked.

The next moment, Leon and his computer appeared back on Ilyana's world, where he usually trains.

"You have got quite the nerve to threaten me like that," Ilyana said.

After a few seconds of silence, Leon finally noticed that he acted without thinking. That kind of dialogue made him feel closer to her, and that wasn't something he wanted. Feel closer to someone who always hides information from him. Regardless, before doing anything, Leon created a room where the wind and rain wouldn't damage his computer. Since some stray shot could fall on that building, he made everything exceptionally sturdy. The price of that was the heat inside of the building...

"Well, it doesn't matter, I can use Cold Breeze to make the ambient more pleasant."

"We didn't ask this before, but what do you plan to create?" Celsius asked.

"Nothing very complicated at first, but since I can create several things using Transmute as long as I understand them, there are several things I want to use. By combining magic and firearms, in the future, I want to create a weapon that absorbs solar energy and disperse it to cause massive damage, there is a limit with the things I can do with magic, but since solar energy doesn't have a cost, it will be useful against the invaders."

"That certainly is an interesting idea..." Undine said. "But will you learn that alone and before the start of the battle? Even if you succeed, that will only happen in the far future. What do you want to create now? I'm quite sure anything you can create using the technology of your world can be replicated using mana."

"You are right, but I'm doing this to relax, remember? For the time being, I will feel satisfied in creating surveillance cameras that can work using solar energy only or, at the very least, some robots to produce mana liquid for me. The effectiveness will decrease, I know, but it will help me save time."

Still, before turning on his computer. Leon had to train for a few days since he spent three days on earth, but thirty passed on that world. Things progressed slowly since he didn't have a target, but Leon was okay with it. Now that he had a new goal aside from revenge, he could do things at a more reasonable pace.
