High Martial Arts Super God: Become Invincible from Refusing Involution

I got the most incredible system in history. It says that as long as you fulfill your wish, you will be rewarded. But I turned down all the assignments. The system collapsed on the spot, and I cried and offered ten times the reward, begging me to accept it. So I became the strongest saint in history, and I seemed to be able to level up even while lying down.
