From the Start, I Sign In with the Nine Dragons Carrying a Coffin: The Grim Reaper Descends

[A villain forced to grow up + sharp-tongued king + negative-emotion harvester + lighthearted + funny + scheming + Grim Reaper's egg] Ye Yan drinks himself into a fresh start. When he wakes up, he discovers that he has transmigrated to the Ancient Tai Ling Domain and become an unborn baby still in his mother's womb. At his birth, a celestial phenomenon appears, and eight dragons carry a coffin to welcome him. “Hey, why are there only eight dragons carrying my Nine-Dragon Coffin? Oh, my old hag of a mother sucked one away. Give it back!” Ye Yan forcibly steals the dragon aura from Ye Han, his unrelated half-brother and the chosen one. The Nine-Dragon Coffin is in position. All aboard! “What? You can collect negative emotions? Easy. I'm a master of trash talk. Every client I deal with storms out, furious, and slams the table. Hilarious! I got another free meal. Couldn't be better.” “What? Hatching this egg lets me inherit the power of the Grim Reaper?” “My brothers abandoned me, my own family died protecting me, the Emperor stole my dragon aura, and my clan was slaughtered. Then let there be darkness! I'll bring chaos to this prosperous age. In this age of great struggle, I, Ye Yan, have arrived!” From then on, Ye Yan walks the path of a villain, going further and further until he establishes an empire for the Ye family and brings peace to the land... A hundred years later, the truth comes to light, and heaven and earth weep for three days...
