Liu Jiagui guessed it all correctly—the car accident was indeed orchestrated by Feng Jun, and it was simple to execute, just a Divine Sense Attack would do.
When he heard that the Liu surnamed still could not keep his mouth shut the next day, verbally abusing others, he sneaked into the hospital at night and sealed off the sensation in his lower body.
Feng Jun didn't kill the man, not only because his crimes didn't merit death, but also to serve as a warning to others.
To him, directly killing Liu Jiagui would have actually been letting the scoundrel off easy. He not only refrained from killing him, but he didn't even intend to leave him in a long-term coma—I want you to live consciously, to feel every bit of life slipping away.
You think you can bother people, create trouble? I'll break both your legs and see how you'll trouble anyone then.
