Slam Dunk: Unorthodox System

A Slam Dunk fanfiction, a system, and lighthearted humor. No bitterness or deep hatred. A quest to save all the unresolved feelings. The protagonist, Lin Feng, travels into the world of Slam Dunk and obtains the Basketball God's assistance system. But why is this system so deviant? I'd call it the most deviant system ever!
