Long Chen could feel that he was going to enjoy the fight. It was going to be fun to watch the girl who had helped to kill Mu Lin get beaten. Even though Long Chen hadn't known Mu Lin personally, he found a sense of closeness to Mu Lin.
Both of them had a similar past. While Long Chen was thrown off a cliff by a bastard for no crime, Mu Lin also had a similar bad fate. He was also killed for no crime. He was also thrown off.
There were only a few differences. One of the differences was that Long Chen was thrown off a cliff, and Mu Lin was thrown into a lake. Another difference was that Long Chen was thrown off the cliff with the intention to kill while Mu Lin was killed first before he was thrown.
Long Chen disliked the girls from his core as he saw a glimpse of Long Su in them.
He also knew that if he met them outside the Ghost Temple, he might enjoy killing them the same way. While he was reveling in the thoughts of torturing and killing them, he heard Xun's voice in his head.
