Donan used that strategy to try to counter-attack Leon's attacks for a few minutes, but soon gave up on the idea and started to move around like a madman punching the walls and empty space while he tried to hit Leon by chance. However, he failed miserably. Donan was using the sounds to find Leon, and whenever he heard anything, he moved to somewhere and attacked…

"I knew it… his body is slowly getting destroyed by that dark aura…"

Leon couldn't use Appraisal without seeing the target with his own eyes, even though he could feel it, that wasn't enough. However, something like that became evident after Leon punched Donan's a few times… that dark aura also had the smell of blood, probably because Donan was bleeding inside of it, but the blood couldn't leave the aura.

It was hard to be sure, but Leon concluded that dark aura consumed a few hundreds of mana points per second. So, it was more than obvious that Donan was receiving mana from something. Despite that, his wounds weren't healing as fast as his body was getting destroyed.

"This is so stupid… his wrath could make him three times stronger, while the dark aura probably increased his power ten times. Despite all that, I don't even have to attack to defeat him."

Still, the hole Leon created was slowly falling apart, and it would become more difficult to hide if he let Donan rampage like that. Solving the problem with magic would be easy, and even though that wouldn't be much satisfying, Leon decided to attack using a combination of magic and physical powers. There was no room for mistake because Leon intended to concentrate all his mana and stamina in a single attack.

"Here goes nothing…"

Leon decreased his weight using Gravity while he tried to increase the power behind his right fist using Stamina Manipulation and Mana Reinforcement. The effects of Rage, Haste, and Lion's Pride were already there. So, Leon just finished everything by flying toward the rampaging Donan. At the last moment, Leon increased his weight using Gravity, and that increased the potential of his punch even more. The result had been shocking in many ways… a thunderous impact echoed through the entire area and even made the ground tremble for several seconds, and that had been the result of Leon's fist hitting Donan's face alone. The entire hole collapsed when Donan's body got hit against the wall. Even though a lot of earth stopped him, the impact made him open a fifty meters long tunnel.

It wasn't a skill that Leon could use, not with the body and status of a mage. Every single bone of Leon's right arm broke, not only that, Leon had several spots where he could see bones and muscles… Somehow, the pain was much worse than the time he woke up on the island. So, most likely, Leon destroyed his muscles, arteries, and tendons. Instead of using just Heal, Leon used Full-Recover when he ate some blue angel leaves and had enough mana.

"Although Rage, Mana Reinforcement, and Lion's Pride increased my physical status, to the core, I'm a mage… my body already adapted to become a long-range fighter. So, I guess it makes sense that punching a stronger person will destroy my fists…"

Regardless, Mega-Punch would be one of the skills Leon would rarely train and use only to surprise his opponents. Putting that aside, Leon walked toward the tunnel he created using Donan's body, there he saw the unconscious Donan covered in blood. The Dark Aura disappeared, so Leon didn't have to worry about anything.

"Mmm… I punched him a lot of times, but only a special skill made me achieve my goal here."

Leon's punch broke most of Donan's teeth, so he was satisfied… to some extent. He achieved his goal, but in the end, that didn't change anything. Darya was alive and was being fed by Donan's lies. Considering everything, it was most likely impossible to restore her memories, Donan wasn't a fool to leave a blind spot like that, after all.

"Hey, dog… wake up," Leon kicked Donan's head.

Leon didn't hold back, but even after a strong kick on Donan's head didn't wake him up. Although he was bleeding, he won't die. However, his body reached a peak of exhaustion, so it wouldn't be weird if Donan sleeps for a week or two. It was annoying, but Leon used Heal on Donan's head a few times until he woke up. However, he was so exhausted that he barely could keep his eyes open.

"Now, we are even," Leon said. "Still, I can't forgive you for what you did to your own granddaughter. However, I know that spell you used probably deleted her memories instead of sealing them. The Darya I knew doesn't exist anymore, you can keep acting as if you care about her, but if you delete her memories again, or let her die, I will return to kill you. And don't think you will die fast, I will cut your limbs one by one and feed you with them… is that clear?"

Donan could only move his head a single time before losing consciousness again, Leon wondered if he would remember that after he wakes up. However, he already gave his warning and wouldn't say the same thing twice. After that, Leon grabbed Donan's by the neck and flew toward the hole Donan created when he attacked Leon… it was time to say goodbye.
