Reborn as a Skeleton, I Can Level up by Killing People

[Western Fantasy + System + Decisive Killing + Cool Text + Single Female Protagonist Sweet Pet + Cat-Eared Lady] Tianxuan Continent is vast and boundless. All races are in it. Lin Nian was reborn in another world and became the lowest level skeleton. When you open your eyes, you are in the skeleton village, where the same race is ostracizing and the weak are preying on the strong. Then—slaughter the entire village, feed on the bones, and evolve through killing! Awaken the undead evolution system, devour bones, unlock magical skills, and command thousands of bones. From the lowest skeleton, fight your way to become the Lord of the Netherworld and the Supreme of Ten Thousand Bones! In the end, Lin Nian borrowed the body of a skeleton to conquer all races, hold the sun and moon, reverse yin and yang, and kill the universe!
