being caught in a beast's territorial war part 1

I left my ruined base and traveled while grinding for beast ranking from 100-130. I made sure the beast I hunted are more than 15 rank below me, just to be safe. among the beast that I mercilessly slaughtered I picked a few corpse to use "[DARK]devour" to raise my strength and acquire useful skills.the corpses I picked are "Titan boa"and"Demonic Raptor" I specifically choose this to exact my revenge.I then gained "[Skill]Detection: use for scouting nearby enemies" and "[Skill] Piercing eyes: an intimidation skill". I also pick "Diamond slime: a slime made with the hardest mineral known to man evolved after absorbing a number of diamonds "this was an annoying battle because of its tenacious quality, but in exchange I gained "[SKILL] diamond manipulation:produce diamond and manipulate it at will". "Ancient forest guardian: a huge tree that live for hundred thousands of years and gained consciousness" it's not hostile I just want to gain "[Nature]forestation: grow all kind of plants in seconds" because it will be useful in agriculture. anyways after being too focused on my "status" panel, a huge crisis came. I felt surprised of what I encountered. without me noticing I was already in the middle of a battle between "chaos beast:once a normal beast but was influenced by chaos and is now a beast with a body envelope in purple darkness corrupt all kinds of life and turn them to beings called corrupted" and "beast of the void: a beast influenced by the power of void and is now a beast with a body envelope in crimson red, slaughter anything that moves, came from the wastelands of another dimension".
