Han Dai

Elder Dongmei knew he could not treat Han Cai as a child anymore; the kid had become more powerful than him, and if that was not enough, he had become an emotionless killer and thief too, but the kid never disrespected him or the sect master. 

Elder Dongmei would brag in front of the core elders and shame them whenever he got the opportunity that the child he raised was more powerful than all of their disciples' strengths combined. No core elder was ready to believe that Han Cai was that strong until Han Cai beat up dark hall elders. After that, the core elders had sweat forming on their heads. 

The dark hall elders that Han Cai beat up were all golden core, and the core elders of the sect were also golden core. This meant that Han Cai was not only stronger than their disciples, but he was stronger than them too.

Han Cai ignored the elder's warning about robbing his targets.
