"I guess I will need to create another replica, one that will only create things for the shop," Leon nodded to himself. "I just hope I will obtain enough mana from this to do other things."

"Thanks, once again, Leon," Hector said after he heard Leon muttering something to himself. "Although you don't look that reliable, you always surprise us with new things that help us again."

"It looks like you are recovering your old annoying habits…" Leon sighed.

"Really? Was I like that when I was young?" Hector smiled. "I just tried to crack a joke, but… now that you mentioned it, it feels kind of natural."

"I also feel full of nostalgia after hearing that," Amanda forced a smile. "How can I feel nostalgia toward something that I don't remember?"

Leon shrugged. It was weird, but nostalgia was one of the things he barely could feel. All thanks to the power to control his own memories. If he wanted to re-experience something, he could do it easily. Speaking of which, Leon also created the tomes that would let his friends learn the same things he did it. If they had the time and enough coins, they would be able to remember about Leon on their own. As much as Leon wanted that to happen, he couldn't demonstrate. So, he didn't lower the price of those tomes. That was one of the reasons. The other was about efficiency. If Leon doesn't recover, at the very least, the same amount of mana he used to create those things, he basically would be wasting time. Precious time that he could focus on increasing his strength. It may sound arrogant, but Leon was fully aware that he was one of the best human fighters, and he couldn't slack off after coming this far.

"Well, I'm going," Leon said. "Since I'm the core of the profession system, I need to unlock other classes and jobs for you guys to have access to. Once I unlock them, I will tell you the requirements to unlock the class. Spread the knowledge about it as you see fit."

Before leaving, Leon watched the silent women who were also with them. It was Maya, his niece. Although she wasn't looking at him suspiciously anymore, she still had a frown on her face. Leon felt quite like he had found a pretty lame goal, but he wanted to become a respectable uncle… but it looked like that would never happen.

"Man, I can never get tired of this…" Leon grinned. "This is strangely addictive… I wonder why."

The system could be improved, but for the time being, it was more than enough. Besides, considering that Leon doesn't have much experience using his new ability to skip steps of things and create new rules for others, maybe it was better for him to keep improving himself instead of the system. That was also the fact that he needed to keep unlocking new classes for the people on Earth to get stronger as well.

"If I only had this system when I was on that island…" Leon sighed. "Well, imagining, that is pointless. It is crazy to think that the system's creator could have saved billions of lives if he had spread this knowledge on Earth. Besides, there is also the fact that maybe that person discovered this after all that happened. Time dilation is insane, after all."

Leon began to make some calculations and then concluded that when Ilyana was probably on the fifth stage of assimilation, Leon got stuck on that island. It was hard to imagine a being less powerful than the sixth stage being able to use conceptual attacks, so it became evident that he only created the system when Earth was already on dire straits. Besides, instead of helping aliens, if Leon were him, he would use the system to help humans. So, hoping that some stranger would do something, he wouldn't was meaningless.

"Well, the knowledge of this system already proved itself to be more valuable than anything, so perhaps…" Leon muttered and then considered a few possibilities. "No… I'm not sure of that yet. I'm not strong enough to do something like that… even if I succeed in defeating the remaining harvesters, there is no telling if I will succeed or not… I need to keep improving until… I obtain unlimited power."
