I Have Just Become a Centenarian, and the Country Invites Me to Seduce the Devil.

(Semi-invincible + Decisive in killing + Unchanged youth + No heroine + No overwhelming combat power) Lin Xiao, the ancestor of the Chantian Sect who took the ancestor system and traveled through time and was reincarnated a hundred years ago, found that the world had been saturated with blood when he woke up. The blood moon hangs high in the sky, sprinkling weirdness and pollution into the world, and folk customs and legends turn into terrifying replicas that devour life. The trialists struggle to survive in the gap between illusion and reality. The whispers of the outer gods seep from under the seal of the stars, and the boundary between the two universes is about to collapse. Lin Xiao looked at the bright red seal of the "Jiazi Demon-Destroying Plan" on the state secret document, and flicked the whisk: "Three thousand years of Taoism, we have the confidence to eliminate the demons." When the relatives of the outer gods screamed in the city streets, and when the pollution of the blood moon eroded people's hearts, Lin Xiao used the thousand-year Taoist law as his sword to cut off all the strange things in the world.
