"I had not asked you to vow. That was your own choice." Long Kael pointed out unhappily. "And how many times have I reminded you to not vow so casually? That will cause your life eventually." He added reprimanded.
Long Cheng tried to grin for the sake of lightening the mood, "You are fair king! You will not take advantage of the weak, I know that" He trusted his uncle and knew that all actions and intention was for the greater good. Since he was also vowing for Lu Meili to be free, then he would not regret it.
However, Long Kael would have never thought that he would disregard Long Cheng's trust in him in the near future when all his rational thoughts were thrown away.
