"Oh, boy... so much work to be done," Leon said after a long sigh.

After five years, the horde of zombies finally stopped. In the end, Leon had to increase the height of the power because the number of zombies was too big. He also had to reinforce the foundation... a big headache giving the size of the island and the fact that the zombies didn't give him a single minute of a break.

"Let's see... I don't want to create other statues of zombies, but I don't have much of choice here," Leon scratched the back of his head. "Creating one for every year should be enough."

Since Leon had to know for how long he had been there, he didn't have any choice. After those five years, Leon was now ninety-nine years old. The more Leon thought about it, the more he felt like it was a foolish situation. Regardless, since many things were getting even weirder, Leon decided to use Mind Summoning and bring a notebook and a pencil. Most likely, those wouldn't last until the end of the trial, but those would help me remember specific questions.

"Why am I facing the monsters in such obvious order? Why am I facing the zombies that made me recall the people that died trying to survive the assimilation?" Leon wrote in the notebook.

Those were the two most weird questions that Leon couldn't understand after thinking for quite a while. The moments he tried to understand the situation and other things were also the moments he didn't delete from his memory, but the more he thought about it, the less sense it made for Leon. Regardless, Leon didn't much time to think about it because a new enemy appeared... gremlins.

"So, those little monsters are the weakest ones that can be found in the third stage of assimilation?" Leon asked. "That is kind of surprising."

Maybe it was about time for Leon to do some labor work and kill the monsters himself. Since the gremlins were fire monsters, they had a bad affinity with Leon's corrupt mana trees. So, the best option was to kill them instantly, and so Leon did. A single Plasma Bullet in the had been enough to kill the gremlins. After that, the corrupt mana trees ate the corpses.

"It has been a while since I saw this... and I'm already sick of it," Leon frowned.

"Let's see... the cheapest summoning spell I can learn now is... Summon Fire Elemental," Leon rubbed his chin. "The monster that made me find Ilyana."

Against the gremlins, the flame elemental would be useless. So, Leon decided to start with the frozen ones. Although Leon would obtain the power to summon them once the gremlins are around the level three hundred, he was sure that it would be fine. The combination of ice and thunder was quite powerful, after all.

In any case, leveling up those three summoning skills to the level max would take at least one decade. Although that was quite a good amount of time, Leon learned his lesson this time. He could have easily leveled up to the max level four or five summoning skills while fighting against the zombies, but he didn't. Due to the circumstances, he was forced to use his most powerful area of effect skills to defeat them, and those were already at the max level, so Leon didn't obtain a single coin and only a few status points.

"Since Aquatic Slimes can be found in worlds in the second stage of assimilation, why are their tomes more expensive and the cost of mana larger?" Leon frowned. "Did Ilyana messed with the prices?"

While Leon was looking for new summoning spells, he found some monsters that he had never seen before. Although the map Yuki gave him had the locations of dungeons that spawned such creatures, he never went to those places. In any case, Mechanical Scorpions and Mechanical Golems and were far larger than Mechanical Spiders, but just as Leon has expected, they didn't have any elemental attributes. Just like the mechanical spiders, they didn't have health and stamina either. Considering their nature and how difficult it would be to summon several of them, it would take more than a few decades to make those reach the max level, but Leon wasn't in a hurry.
