The first task is to let him, a paralytic, win the Olympic running championship! Isn't this a fantasy? After being tortured by the mission for three years, the desperate Lu Fan was about to commit suicide, but accidentally saved Bulma's father, obtained a mechanical exoskeleton, completed the mission, and regained his health.
But the system still wouldn't let him go, and issued various weird tasks, such as beating up the 11-year-old Monkey King! If he can't defeat him, he will outsmart him. Lu Fan successfully becomes friends with Sun Wukong by using delicious food, and gets a reward that increases his combat power. During an adventure, Lu Fan took a mysterious pill to cleanse his essence. Not only did his strength greatly increase, but his appearance also took on a new look.
As the adventure progresses, his relationship with Bulma quietly heats up. However, behind King Quan's arrangement for his time travel, there is a surprising secret hidden: Sun Wukong will turn black in the future and will be unbeatable in the universe, and Lu Fan is the key to changing all this. Can he complete the many tests of the system and rewrite his destiny in this Dragon Ball world full of dangers and opportunities?
