@AmaraSol its not like he was imprisoned for the whole 4 years. He have a lot of chance to let woowoo know how he's doing and yet he failed to do so. It is and more understandable if he was imprisoned for the whole 4 years just what on the previous chapter, he mentioned doing mission for the italian mafia meaning he wasn't detained do probably being monitored but i'm sure have chances to let woowoo know. He seems to have forgoten that Qu Cheng still the boss of a powerfull gang, he should have ask for help instead.
