The game hasn't even officially launched, and he's already become the short-lived husband of the future Empress Liu Hanyi—that good-for-nothing young master who dies a year after marrying into her family!

"The famous Goddess of Slaughter, Ji Fei, is actually your maid?!"

"And the Nine Heavens Sword God, who can cleave immortals with a single sword, is just your butler?!"

The reincarnated Empress is stunned. You call this a useless son-in-law?!
