I Kill Immortals and Demons in Troubled Times

The roots of the dynasty have long been hollowed out, and the lintels of the aristocratic families are full of withered bones. In this purgatory where human life is like grass, the great demon regards the city as a pasture. I would like to ask the common people, how can they survive? Is it just begging for mercy and living an ignoble existence? Let's use blood as salary and bones as firewood to fight a bloody path to the sky! Shen Zhui, who traveled through time, was trapped in the lowest level of prison, but accidentally awakened the [Evil Punishment System] - killing traitors can gain skills, and slaying demons can gain talents. He started as an executioner, and everyone under his sword was someone who deserved to be killed. At first, he just wanted to survive in this cannibalistic world. But when he killed the sanctimonious "immortals" one by one and killed the "ancient demons" who sacrificed human beings... Suddenly looking back, he saw the corpses of gods and demons under his feet, and the broken sky above his head. The once unattainable ten thousand year orthodoxy and the immortal dynasty were all trembling under his blade. "If there is no justice in this world, my sword is justice!"
