As expected, the more the replica got stronger, the cost of keeping it existing increased, it would take a while, but eventually, it wouldn't be that efficient. The best way Leon could efficiently use that method to get stronger was to by summing his replica that received the knowledge after sleeping for a few hours.
"Things are starting to get even weirder..." Leon frowned. "Now I'm summoning copies of myself as if I'm copying and pasting files of a computer. Although that is an efficient way to get strong, it is really problematic that several individuals have the same power, and they don't have my noisy conscience."
In any case, Leon could keep ten replicas of himself active as long as he doesn't do anything but keep using Mana Magnetism, he could create a lot more if he uses his Soul Eaters, but he decided to let them continue to absorb the monsters mana. Instead of worrying about increasing his mana and intelligence passively like that, Leon resumed his training.

After learning the mana and stamina version of Dragon's Vitality, Leon resumed his experiments. As expected, the monsters he summoned using Mind Summoning still had their memories, so Leon quickly managed to learn several spells. Although he had to use spells like Mind Control and Mind Melding to make and the cost of mana to keep all those spells active wasn't low, it was worth the hassle.
"I can assimilate the knowledge and experience of my replicas, but the same process it isn't so simple with monsters," Leon rubbed his chin after he failed in copying Fire Trap, a skill that he had never seen gremlins using but actually have. "I guess it is only obvious given that they are monsters and their bodies work in different manners."
Regardless, even though Leon couldn't copy every single action and skill of the monsters as they do, he could customize them, and so he did it. It was quite surprising that monsters had the knowledge of runes, but Leon felt thankful for it instead of confused. Maybe one day, he would be able to create his own runes and thus different effects, but he still had a long way ahead of himself, considering that he had only a few spells that used those.

"Well, even though those are basic spells, I can use them quite frequently even without waiting for them to activate," Leon said. "Putting that aside, even if I level up those skills to a decent level, I will need ten thousand more points to meet the requirements to learn Foresight finally."
Leon still didn't have even thirty percent of the coins necessary to buy the skill, and considering his progress so far, he wouldn't learn it alone. Thanks to that, he started to wonder if it wasn't a waste of time to buy it. In the end, he could learn a lot more skills by copying from monsters and also buying tomes.
It has been a long while since Leon felt hesitant in doing something. It was a useful skill. Who didn't want to see the future? It was as appealing as it was dangerous... In the end, the only thing Leon could actually do as to think while he practices his new spells.

Unfortunately, training didn't make things easier for Leon. On the other hand, even if he decides something, he probably wouldn't learn the skill in the next few months or even years, and he didn't have enough coins to buy it. So, Leon was at least safe from the temptation.
"If only I could learn a spell like Dark Aura... I would be able to hibernate without worrying about anything until the day this dimension disappears," Leon said after a long sigh. "Well, first, one has to make some replicas and order to mediate day in and day out, but it is pretty clear that Dark Aura would increase my strength exponentially."
A long time has passed since Leon had to deal with Donan; by the day, his hatred for him was decreasing. Still, even at the moment he hated him the most was that exact day, Leon wouldn't be able to force him to use Dark Aura over and over again just to study it. Leon still believed that he could learn something like that without the power of the spirit, he would find a way, but to do so, Leon would have to make Donan die several times... he was one of the worst sons of a bitch Leon had even met, but Leon wasn't cruel enough to make him taste the same death over and over again.
