Chapter 509: Leons Speculation (2/2)

Although he managed to slice off half an arm, the attack was not as clean as he had anticipated. Evidently, the mutant was not only physically strong, but their bodies were also incredibly robust.

After sending out his divine sense, he understood the reason.

The mutants' inner structure was almost entirely encased in bones like a hard exoskeleton shell protecting its vulnerable organs.

The heart was black like its blood, but it was strangely filled with abundant amounts of lifeforce.

Leon watched as the mutant's bones rapidly grew before a new arm was formed, albeit without its layer of tumorous flesh.

Unsurprisingly, these mutants also had extreme regenerative abilities.

However, they seem to belong to a different class from the fleshly abomination. The fleshly abomination could regenerate its flesh while the mutants regenerate their bones.

Even so, the mutants were not hard to deal with, once Leon learned of their weakness.

After driving his bone spear through their hard skeleton shell, penetrating their black heart, and scorching it with his flames, the mutant's resistance became weak, seemingly lost all its strength.

”Oh? It's not dying yet? Such impressive vitality.” Leon commented with surprise before withdrawing his spear from its chest to finish it off with a penetrative blow to its head, destroying its brain.

Afterward, the mutant finally died.

Screee!

The other mutant cried with a high piercing pitch like it was mourning for its loss before pouncing towards Leon in a frenzy.

However, its entry-level Transcendental strength was no match for Leon.

With each swing of his bone spear, a limb was removed from the mutant's body, one after the other, until it finally fell flat on its back, limbless.

Leon stomped on its chest, stopping it from getting back up before he tried communicating, ”Can you understand my words?”

Screee!

The mutant struggled furiously while its limbs were regrowing.

”I suppose not.”

Shortly after ending the mutant's life by destroying its heart and brain, Leon returned to Duna's location promptly.

”You look a little disappointed.”

”Well, I did expect them to put up a stronger resistance than that. But then again, I don't know what the heck they are. They are neither humans, beasts, nor demons. Any ideas?” Duna replied with a nod before hopping off the boulder she was seated on.

She was only able to witness his impressive display of brute strength and none of his other abilities. To say she was disappointed was not wrong.

”If I'm not wrong, these mutants might have been survivors from the Cataclysm over 10-thousand years ago,” Leon made a guess after some thought while they were beginning to leave the subterranean space together.

”The Cataclysm from 10-thousand years ago? Are you sure they can live for so long, given the sort of extreme regenerative ability they have?” Duna responded with doubt before adding, ”I would not be surprised if such ability even shortens their lifespan.”

”Well, it's just a guess. I could be wrong. However, I don't think I am. At least, I believe these mutants should be related in some way. I can't think of any way these mutants could possess such grotesque appearances other than getting scorched by the sun's solar flare during the Cataclysm directly without Gaia's atmospheric protection.”

”Without Gaia's atmospheric protection?” Duna was surprised before she asks, ”You mean they might be coming from…?”

”The void.” Leon nodded while pointing directly upwards.
