In the end, it took Leon two years for him to obtain enough coins to buy the Mind Shifting tome. Although it had been two long years, he imagined they would be worthy of the wait because he had some ideas of using that spell, aside from deleting his most boring memories.

"Oh boy... one thousand mana per second?" Leon frowned. "I should have expected that give what I can do with this skill, but still..."

Leon could accelerate or slow down the process of how he reexperiences his memories again, but there was a limit. Besides, he couldn't be careless, the chances of him deleting some unnecessary memories in that imaginary dimension were low, but the chances were there.

It already had become a habit, so Leon used that skill for several days until it reached the level two hundred. Thanks to Mana Magnetism, Leon leveled up the skill very quickly and deleted some of his memories when he was training his spells. Leon only didn't delete the memories where he learned new skills or managed to make others reach the level max.

"As expected, I feel less mentally tired and bored now," Leon nodded to himself after analyzing the changes he made. "Still, I have to be careful and not delete the memories that tell me why I want to delete some memories... this is a bit confusing, but I guess it is impossible to happen since I'm always thinking about the reason. Well, now... it is time for the second test."

Just like many spells have more than one application, Mind Shifting could do more than create and delete memories. Instead of deleting the memories of a target, Leon could transfer those memories for himself. Although that would go against Leon's previous plan, Leon had to test if something was possible. Since his mechanical spiders reached the level max, it was time to learn a new summoning spell, and Leon found the perfect creature to do that.

"They are pretty strong for a level one monster... their potential is terrific, but I already expected that given that I had to spend one hundred million coins to buy the tome," Leon said.

The island was currently being attacked by devourers, even though those monsters weren't that strong, they were quite problematic, so Leon hurried to create as many as Ghost-Swords as possible. However, five of them he just gave the order to attack the empty hair for a few hours. After that, Leon used Mind Shifting and absorbed their memories.

...

"Hehehe, it does work," Leon smirked.

Although it wasn't the same thing, it was similar. By making his monsters do something like swinging around their bodies for a while, by assimilating those memories, Leon received the same kind of experience he would obtain by training with swords. That kind of application was really interesting and useful. However, Leon's surprises didn't end there.

Congratulations! You have learned the skill: Mind Absorption.

"What the heck..." Leon frowned.

Despite the surprise, Leon had already found a tome that could teach him that skill. The problem was the price... one hundred billion coins. Given that information, it was clear that Ilyana's wasn't just putting random prices in the items in her vault. Regardless, Leon didn't expect to learn it just because he combined Mind Shifting, Omnilingualism, and Mind Melding.

"I guess the requirements of Mind Absorption is exactly that, use those skills at the same time," Leon rubbed his chin. "Still... I didn't expect to save one hundred billion coins, just like that."

Mind Absorption was even more powerful than Mind Shifting. Even though he couldn't use that on his summoned monsters, Leon could use that skill to obtain all the knowledge a monster has. Skills, spells, levels, battle experience... Leon could obtain them all by using that skill. The price to use the skill was high in mana, but he also would have to keep stored in his mind the lives of the monsters he uses that skill.

"There is a way to counter that... If I just absorb the exact moment a monster learned skill, and grind the skill myself, I will be able to delete the memories without losing the skills and levels," Leon said. "But it will be hard to find those moments."

In the end, even stupidly powerful and useful skills like that have limitations and drawbacks, but Leon was pretty much okay with it. Skills like that were much better than Summon Zombie that didn't have any apparent weaknesses, and Leon didn't do anything to deserve to have it.

"Mind Absorption won't work on the monsters that this place spawns either since they are created a few moments before they appear," Leon said. "Still, it doesn't matter."
