Rebirth: Degenerate Slave Abuses Tyrant - Chapter 80

The formless ancient world was infested with despicable demons. They hunted and feasted on mankind, keeping the human civilization constantly in a weak and suppressed state.

Wei Huo has been ignored and overlooked by almost everyone his entire life, including God. In a bid to transform the world into a more game-like one, God halted time for all humanity except for Wei Huo, leaving him to fend for himself.

When a person dies, they either die light as a feather (aka unimportant) or heavy as Mt. Tai (aka very important).

A lecherous army special task force soldier from 21st-century Hong Kong is selected to travel back in time, choosing to go to the Chinese Warring States Period. Unfortunately, the time machine runs into an error during the experiment. With no foreseeable way to return to the present, he must use his combat skills and knowledge of history to thrive in his new life in the year 251 BC.
