In the end, Leon found a way to increase his status using his own energy. However, it was incredibly difficult, annoying, and probably not efficient. By concentrating his own mana in a single spot and let his body absorb that same mana, Leon could increase his own max mana. However, to do that, Leon had to concentrate a lot, and thus he wouldn't be able to use any other spells. Besides, to increase a single point of his mana, Leon had to spend one million points of his own mana.

"I found the skill I was looking for, but I didn't expect to be so difficult," Leon frowned. "I can't stop in the middle of the process of gathering mana... so I can only rely on my recovery to obtain enough energy, and I also can't let the mana crystalize and become mithril..."
In any case, Leon was sure that he could do the same thing using his stamina and health. Health Sacrifice would be a little more difficult to learn because Leon barely trained the spells that consumed his own health.
"Using this kind of skill will be difficult, and I bet I can increase my mana much faster just by learning new spells and training the old ones," Leon concluded. "Still, the other versions of this skill will be necessary for me. Even though controlling stamina and health will be difficult, there is a way to ignore that kind of problem. I just have to outsource the whole process."

After learning those skills, Leon created spirits and gave them the knowledge of how to use the same skills. Although it was annoying to repeat that process over and over again since the skills were at a low-level, that worked better for Leon because even though the skill couldn't get more efficient, the cost of energy consumed by every second increased a lot.

"Mmm... I should have left the skill at the level one," Leon frowned, when he noticed that both rings could kill him if he gets careless. "No, if I had upgraded the rings only a single time, I would be able to keep them even while I sleep, but now I will have to be careful."
Although Leon made a mistake, that mistake granted him the opportunity to notice several problems of those rings. As expected, when Leon equipped the rings, he felt like a monster was biting his fingers and draining his energy. Thanks to it, Leon noticed that he was also losing his vital force... it was the same process when he recovered after losing a lot of blood. Little by little, Leon was losing weight.
"I will have to increase the amount of food I have to eat," Leon nodded to himself. "While that isn't so bad, losing vital force so frequently might be dangerous."
In any case, even though that was problematic, that wouldn't make Leon lose some nights of sleep. Fortunately, the rings could store the energy they drained from Leon, so he could resume the process or stop whenever he wants.
Regardless, thanks to those rings and skills, Leon would be able to increase his health and stamina without doing anything except spending status points. With one less worry in his mind, Leon decided to train for real again.

Although Leon spent a few weeks training those spells and his discovery of how to increase his energy was still recent, he was starting to feel like learning something impressive again.
"I guess I'm about to learn the ���whatever's Greedy," Leon said. "I still have some coins to spend, but considering that I don't know how long the zombies will attack me, it isn't a good idea to spend it."
Leon's only option was to learn something new alone. While that wasn't entirely impossible, it would be difficult since his Soul Eaters weren't absorbing more mana since the zombies didn't have any.
"Well, even though it will be more difficult and troublesome, I will feel more proud of myself after it," Leon said. "Still, what can I possibly learn that will be as incredible as my last achievements?"
Leon thought for quite a while, but in the end, that kind of inspiration could only come in a rare moment, and it was beyond his control. The only thing Leon could do was to keep training and keep his mind sharp.
