In the Prehistoric Period, I, Hongyun, Became Stronger When I Lay Flat. Hongjun Was Anxious.

I traveled through time and became the hapless Ancestor Hongyun who was destined to perish. He was bound to the "Ultimate Salted Fish Lying to Win System". I originally wanted to live forever, but because the system's rewards were too generous (you can become stronger just lying down), it attracted the jealousy of various bosses and was forced to be involved in the calamity.
