Yang Kai was so ruthless precisely because he wasn't only in for the reason Sun Honghai had him sent here.
Mainly, it was because yesterday, a lawyer visited him, asking him to take down Sun Honghai.
He was assured that if he dealt with Sun Honghai, he wouldn't have any problems.
Moreover, the lawyer also said that as long as he crippled Sun Honghai, they would use their connections to reduce his sentence, and when he got out, he'd be given a million.
As for who sent the lawyer, he didn't know.
But he knew there was no need for the other party to lie to him.
Plus, he already harbored a bone-deep hatred for Sun Honghai; he was willing to do it since crippling Sun Honghai wouldn't get him in trouble, it might even reduce his sentence, and there was a million waiting for him upon his release.
Thus, Sun Honghai ended up in his current predicament.
"Yang Kai, aren't you being a bit too brutal?" a prisoner jeered through laughter.
