In the end, Leon had a hard time thinking about it. He could heal wounds, but the wound on his shoulder was already healed, there was nothing to heal left. Leon tried to make his arm using mana and tried to stimulate the mana, but nothing happened. That would be very hard... if he couldn"t heal, the only way to regrow his arm was to multiplicate his cells. Heal repaired dead cells... so he had to learn the method to heal a cell so much that one would become two cells.

"That sounds somewhat unpleasant... I feel like if I make a mistake, I will end up creating a monster copy of myself..."

Anyway, Leon had no other choice but to try. After focusing his mana as much as possible on his shoulder, Leon stimulated his mana inside the cells, but there was no change in his body.

"Well, until I have a better idea, I will keep trying."

As it turned out, Leon didn"t think of anything. So, he kept trying for two days straight, and then when they reached the Brazilian territory, it happened. Leon"s theory was right; he could multiplicate cells by stimulating them as much as possible. However, Leon felt terrible pain. His body trembled, and he lost the air his lungs, and then the earth platform started to fell.

"Wha… Hey, Leon, what is going on?" Betty shouted, noticing that they were falling.

Sasha, who was sleeping, woke up and grabbed her weapons only to notice that no enemy was nearby. Both of them saw Leon trembling, his face was pale like a ghost, and he couldn"t hear them. Although that was a problem, the fall itself wasn"t dangerous. Betty grabbed Leon"s body, and then they jumped from the earth platform and landed on a beach. A few monsters approached, but Sarah easily killed them while Betty was looking after Leon. They finally noticed after several seconds why Leon so much pain. His arm had been regenerated… at least a small part of it. They didn"t know how, but Leon recovered three centimeters of his lost arm. However, Leon only stopped trembling and recovered from the shock after half an hour. He felt like he tasted h.e.l.l and just wanted to rest, but after noticing how much his arm had been healed and after looking at his surroundings, he got up.

"Let"s go… now I can finally focus on the mission." Leon said.

"Wait, you should rest a little," Betty said. "You looked like you were being electrocuted from inside, you know. Although you learned the skill, it isn"t something so convenient."

"I learned the method, but not the skill," Leon said. "I will probably learn once I heal my arm completely. However, I will do that after completing the mission. We don"t have time to rest. Just look around."

Sasha had already noticed, but Betty only saw a ma.s.sive destroyed forest around them after Leon mentioned that. In the distance, they couldn"t see anything but burn down trees and smoke. The monsters horde pa.s.sed by that place a few hours ago…

"Are you really fine?" Betty asked.

"Yes, I"m sorry for scaring you two," Leon said. "It looks like we can regenerate lost body parts by forcing the cells. However, multiplication of the cells using mana alone is like trying to stretch our bodies beyond the possible… I felt like my very soul was being pulled out of my body."

"That sounds… unpleasant." Betty frowned.

"Anyway, let"s go," Leon said.

Leon created another earth platform, and they began to fly again. He hadn"t told them, but that power had many demerits. The pain caused couldn"t be alleviated by endurance and mentality. Other skills that also worked to decrease pain had no effects since that was a counter-effect of healing a lost body part.

Leon began to wonder if there was another way to regenerate his body like that. The pain he felt was h.e.l.lish… it was almost unbearable that it wouldn"t be strange if some people decide to live their lives without a limb rather than feel such a pain. Anyway, Leon was worried about Gisela, the pain he felt mostly was in his body, but he didn"t feel pain in the head. However, if he tries to heal her eyes, the pain would be much worse, to the point where medicine to dull the pain would be almost useless.

Leon was worried about those effects, but soon he was forced to forget them when they finally catch up with monsters" horde. The monsters were trents, snakes, harpies, and many types of oversized insects. However, what caught Leon"s attention were thousands of T-rex that he could see. Those things were huge, and just their appearances were enough to Make Leon feel s.h.i.+vers. He saw pterodactyls and velociraptors now and then, but the totally forgot that someday he would be able to see those humongous creatures.

Leon started to wonder if his skeletons would be enough to kill so many of those creatures, and then his doubts disappeared when they had to fly for several kilometers to surpa.s.s the horde of monsters. His skeleton army would have no chance; those creatures would arrive and attack Fortaleza in two days. Unless the survivors managed to store hundreds of thousands of potions, Leon wouldn"t be able to build the army to stop them… and that horde was just a fraction of those monsters since many others were going to the other four cities.
