So the guy quianqiu that's been trying to brawl with our xie lian is currently the martial g** of east, in his human life he used to be a prince of a country called yongan and his martial arts teacher was xie lian (in his human life) ... but soon some people of opposing country called Xianle planned to massacre the royal family but xie lian reaches just in time before they kill the King of yongan ( quianqiu s father) and they all retreat but now the king of yongan is enraged and he orders to kill everbody of Xianle kingdom as revenge hearing this our xie lian is in shock and cannot accept it so to save the lives of millions he kills the king and right when he does that the prince - quianqiu enters and catches him red handed and then later stakes him .... so the real culprit of yongan nobels massacre were prince an le, qi rong ( green ghost) and some rebels of xianle kingdom ... so now when the martial g** is accusing our xie lian our hua cheng knows the truth and also the fact that martial g** himself knows something and as he finds out from the green ghost after all those beatings that it was the martial g** that killed prince an le one of the culprits so he shouldn't be accusing xie lian and that's why he brought xie lian and made the green ghost confess infront of him i think to help him not feel guilty or anything
