In the past, Leon had to watch his skill list in order to think of new spells unless he has some sort of sudden inspiration, but Mana Eyes changed that. Using his own spells, Leon could see how they worked in a manner like he never did before and thus think of new ways to use them. That kind of change was enough for him to learn new spells.

"The names are getting less objective, but instead of that, I wanted to cost of mana could decrease..." Leon sighed. "My mana pool is getting larger, and recovery is also growing by the day, but it isn't enough."

It looked like the problems of mana would never leave alone. Even though he could recover five thousand points of mana every second, thanks to Mana Magnetism, he wanted more. It was a wonder that Leon didn't obtain the lion's greedy or something. Maybe he didn't obtain such skill because a person could only have one, and Leon's pride was more powerful than his greedy for power.

There were many things that Leon couldn't understand about that kind of skill. Regardless, even though that kind of thing was useful, Leon didn't want to put more restrictions on himself. To use Lion's Pride, he had to fight alone. Donan had to get mad and predictable to activate Wrath of whatever, so that was a problem as well.

"I wonder if Ilyana has that kind of skill..." Leon rubbed his chin. "I never saw her eating anything, so if she has that kind of skill, it isn't gluttony. Since she rarely leaves her castle, perhaps sloth is her deadly sin, but how would that sin work in her benefit?"

Putting such questions aside, Leon resumed his training. Although it was a pain, he ended up creating another island using Earth Manipulation and Geomancy in order to cultivate the blue angel leaves and train the skills that increased the effects of potions. It took a little while thanks to that, but Leon eventually managed to create a Soul Eater. He probably could have done that a little earlier if he had created a sword and given the effects of a magic box, but Leon decided to follow plan A just to because he felt like it.

"The best way to collect mana using Soul Eater would be to create them and pass them to my death knights," Leon said. "I'm pretty sure I can control them to do that... the problem is, that skill is already at a max level. Geez... I'm really greedy for mana. I can recover using plants, mana fruit, Mana Magnetism, and now I even want the mana from monsters."

Fortunately, Leon couldn't think of any other way to recover his mana. Otherwise, he would work toward obtaining it. After noticing that was indeed the case, Leon started to think that maybe it was time for another session of endless grinding. He had already used Skill Bestowal and created some Soul Eaters and gave them to his summons. Still, much to his surprise, he would have to look for new ones, because he was already using the mechanical golems, and they were already at the level four hundred.

"Even though I'm not creating them all that frequently, the battles against monsters of the same level increased their growth speed," Leon concluded. "Even though I decided not to use buffs to help them... those creatures are sturdy as hell."

Leon experienced how hard it was to deal with inorganic creatures, but it looked like regular monsters were particularly bad in dealing with creatures like mechanical golems. They were immune to negative status, after all. Besides, they didn't feel pain when they were attacked.

Regardless, even though worrying about new summons was difficult, it was only for a while. Leon decided to focus on the monsters himself once Farming, Alchemy, Potion Creation, and Enhanced Potion Creation reach the max level. It would take a few years, so Leon would have to buy a few more tomes that grant him summoning spells.

"This should be enough..." Leon said.

Although Leon felt like he was continually being troubled by summoning skills, he only felt like that because he was deleting his memories since it always takes years to make a summon reach the max level. Regardless, Leon summoned his new monsters and tested them in combat. Death Machine was another robotic summon. Unlike the previous ones, it didn't have an animal-like shape. It resembled the boss that Leon fought when he arrived on Miebos since it could shoot Mana Bombs like a machine-gun.

The other monsters were also weird. They were basically stones made of ice and fire that floated without doing anything. They could slowly freeze and burn whatever tried close to them, but their real power was activated when they were about to die... they caused a self-explosion that caught Leon by surprise the first time it happened. Still, even though their power was weak at the beginning, the cold core could freeze half of the island once it reached the level two hundred.
