Ultimate: Brother-in-law Linglong, I just want to slack off.

Su Luo travels to the Ultimate Series Gold Dimension and awakens a god-level mission (and slacking off) system.
You can get various rewards such as combat power index by simply completing tasks!

From then on, he resolved to become a ruthless task machine.
KO rankings? Not interested!
A battle between good and evil? That's none of his business!
Boss? I wouldn't even be a dog!
All he needs to do is complete tasks, fish, and chat with beautiful women to be invincible across all twelve timelines!
Eighteen years later, after his coming-of-age ceremony, he was dragged by his family to a blind date, only to find that his date was Hua Fulong. So, he was actually Hua Linglong's brother-in-law.
