Later, Yu Hai practiced evil cultivation and killed countless people. Yu Rou sacrificed herself to save Ye Chenghong, blocking Yu Hai's attack and perished in the Underworld. Under the joint assault of Ye Chenghong and Gu Zhongyi, Yu Hai fell off a cliff.
Back then, Ye Chenghong sent many people to search the bottom of the cliff, but Yu Hai's body was never found. The matter fell into oblivion. No one knew that after falling off the cliff, Yu Hai escaped capture and founded the Poison Medicine Sect.
A few years later, he returned to the Guh Family in a wheelchair, pretending to be helpless and alone, seeking help from Guh Tian. Seeing that Guh Hai was no longer a threat, Guh Tian sent him abroad, treating him well, effectively confining him.
Guh Tian didn't know that his brother was the respected Sect Leader of the Poison Medicine Sect. Nor did he know that his granddaughter Guh Siyi's mentor was actually his own brother.
