In the end, Leon didn't spend much time on the centaurs' world. He didn't face any problems there, the only real dangerous situation he faced was when he appeared, and hundreds of archers tried to kill him. Aside from that, nothing happened, and he didn't learn anything new. Besides, the number of centaurs he faced was severely lacking... the fact that they used tactics like that wasn't because they weren't that smart. It was because it was their only way to increase their chances of survival.

"Well, I leveled up some skills up to the level one hundred. So, not everything is bad news... Still, what now?"

The best way for Leon to gain some status points was to fight some powerful enemies, and the best place to fight was on the world that were on the third stage of assimilation. If Leon could reunite his friends and practice with them, things would evolve by leaps and bounds, but was that even possible? Those guys became enemies over the course of nine hundred years. Besides, Leon would have to waste some time organizing that kind of thing...

"I must forget that kind of idea... I don't have the time or the right to babysit them."

Although Ilyana saw a potential that she couldn't find in people that managed to keep their fighting spirit burning for years like Gisela and Yuki, Leon, on the other hand, was kind of unstable. He already knew that helping him was a bet Ilyana decided to make, but despite the hardships he had to endure, Leon wasn't mentally strong. He did everything because he wanted to reunite with his family and friends. Although such a person could become dangerous, only someone who was mentally strong to pursue revenge for hundreds of years could achieve their true potential... At least that was what Leon imagined that Ilyana thinks.

Leon knew that whenever he starts to think too much about things, his progress would slow down. The best way to avoid that was to buy some tomes and practice them for a change of pace, but since Leon already starting leveling up his old skills up to the level one hundred, he decided to keep doing that until the very end.

"There is also the option of facing Crik again. I bet I could level up my skills at an insane speed training with him... but something was off about him. There is also another problem... I would have to ask Ilyana for a favor in order to meet him, and I even don't know in which stage that world is."

In the end, Leon decided to look for the dungeons that spawned the most troublesome enemies first, near the places that have no humans. That way, Leon would avoid hunting monsters that could make other survivors grow strong and prevent those creatures from harming the planet.

"The most troublesome monsters are the gremlins... but I already exterminated hundreds of thousands of them."

The best places to hunt would be in dungeons in Africa and South America. Although Ilyana's dungeon was there, she was sending her monsters periodically to the world where the mithril people are. So, she probably didn't have the need to make her monsters hunt other monsters. Gisela's camp was in Europe, and considering her strength, Leon doubted that she and her friends would suffer many losses even if all the monsters in Europe and Asia try to attack them. Japan's territory was under the total control of Yuki, and Australia also became a walled country.

"I guess I could give a hand to Hector and Amanda... It looked like they regained their fighting spirit after that battle, but I doubt that those years of peace won't be difficult to leave behind. No... it is exactly because of that that I can't help them."

In the end, Leon headed toward Africa to kill some three-headed salamanders and Man-Eater plants. He couldn't relax on his resistance training, so those creatures would help him with that... even though Leon had a hard time enduring the shivers that the tentacles of the Man-Eater plants gave him for some reason.

Although fighting such opponents was troublesome since Leon wanted and could only use those low-level skills, it wasn't so bad because Leon had to focus on their attacks more in order to avoid getting hit in vital areas.

"I wonder if just this is enough to protect my planet from the monsters..."

"What do you mean?" Celsius asked.

"I mean... the harvesters will attack this world when it reaches the fifth stage of assimilation. When that happens, won't the dungeons that connect this world with worlds on the third stage of assimilation disappear?"

"Probably," Celsius said. "... but did you forget that you visited that had only single weather before? Worlds that only had deserts or were covered in snow and ice... those worlds didn't become like that due to the actions of harvesters."

Leon nodded, doubting himself was already a habit, but he understood that his actions weren't meaningless. Leon recalled the world of the slimes that he once visited... even small and weak monsters could destroy entire planets. He certainly wasn't wasting time in decreasing their numbers.
