478 Chapter 476

"It has a lot of health, mana, and stamina, considering that it is only a mutant monster of a world that is in the second stage of assimilation," Celsius said.

Leon nodded, it wasn't weird that the creature was causing problems and hundreds of grizzly giants had to face the thing at the same time. He arrived on time to see a battalion of them shooting steel arrows toward the beast, but the projectiles only caused scratches.

"Their bows are big like their wielders... the power should be greater than any normal bow. Still..."

Although the grizzly giants were tall, they liked light armor. In fact, Leon couldn't see a single one among those hundreds of warriors wearing heavy armor. Their weapons were bows and lances. Weapons that had a big range and could keep them away from the monsters. They were a race that survived the assimilation for decades, but it looked like their nature didn't change. Either they didn't like to fight, or they always focused on winning the battles without suffering any wound.

Even though they were equipped with magic weapons, only a few hits were necessary for the mutant devourer to break those. Those creatures were powerful, but not powerful enough to do that. Leon noticed that when those things got too close, the magic weapons little by little lost their glow.

"Oh boy...their presences alone suck the mana of everything around. I want to learn that. "

"That is a skill the monster evolved at random when it suffered the mutation," Undine explained. "Even though the other mutant devourers probably have that same skill, I doubt that you can replicate or even understand as of now."

"Thanks for the vote of confidence..."

Despite saying that, Leon knew that it was true. If he could learn such a technique, Ilyana would have taught him since mana could increase Leon's training speed exponentially.

...

Leon frowned when he received those notifications again, but soon understood why it appeared. While Leon was talking with the spirits, the grizzly giants finished off the mutant devourer, and some of them looked around in search of something. It was quite an interesting way to level up skills. Leon wasn't spending more mana than usual, after all.

"The problem is... how the heck will I manage to stop the monsters from appearing and then leave carrying all the corpses?"

"The grizzly giants will probably enter the dungeon to investigate the very moment the mutants stop coming... I can't help them directly and let them see me. So, if that happens, they will probably die since the monsters have the advantage in a confined space."

It would be a pity, but Leon didn't come to save some lives. He had come to that world in order to make things a bit more convenient for Ilyana in the future. Regardless, Leon had to wait for several hours until things got dark and quiet. During the day, the number of attacks by the mutant devourers was intense. At least one every ten minutes was bound to appear. Thanks to that, Leon saw several grizzly giants being knocked down unconscious. They weren't that physically strong, either... Leon saw some of the warriors' arms being broken like twigs.

"It doesn't make any sense... but it looks like they even disturb the mana inside of living beings' body and make them frailer."

Leon wondered if things would be fine with him, but considering that Ilyana said that he had to drain their mana, it wouldn't be that difficult. It was a mutant version of a monster in a world that was on the third stage of assimilation, but Leon would be fine as long as he is careful.

At night, some warriors watched the entrance of the dungeon, but since the mutant devourers didn't appear that frequently, they relaxed a little, and Leon obtained his chance to enter the place. Using Transfer, he appeared inside of the dungeon and behind the guards. They had good instincts and felt the presence of something behind them. But when they turned around, they found nothing. The giant grizzly guards waited for a monster to appear for a while, but after a few minutes, they relaxed and just shrugged while looking at each other.

Leon sighed in relief when he activated Mana Dominion and confirmed that no one was following him. However, he couldn't help but worry when he didn't feel any signs of monsters in the range of his skill.

"That is weird... I already don't understand how this place can spawn only mutant monsters, but I can't understand why it spawns so frequently during the day and almost nothing at night."

Leon didn't know anything about monsters' biology. He doubted that even if such a thing exists could be applied to a mutant species. But it looked like the mutant devourers were a species that only could function well during the day. Leon found the purple crystal, but there was nothing weird in any place.

"Now what?"
