Not want Long Jie to succeed Long Shaoming

Inside Long Shaoming's study. 

"What were you thinking, Shaoming? We discussed it before. You announced your retirement without even discussing it with the family. "Elder Long was enraged. How many times had he told his son that he didn't want Long Jie to be his successor? It was not because he was not capable, but because he would destroy the centuries-old legacy. He would destroy the family for revenge. Or this was what Long Yuhan had been telling himself for years now. 

Elder Long's actions were enough to indicate how much he hated and loathed Long Jie and why did so was still unknown. He did everything in his power to keep Long Jie away from the family but then his wife and Long Jie's grandmother had to come and screwed up all his plans. He made sure Long Jie never came back but he returned one day and terrifyingly transformed into something -- he couldn't decipher until now.
