Compared to Wind and Rain City, Liuhuo City was actually closer to Dragon Tears Valley.
When the Devils in Dragon Tears Valley were gathering, Liuhuo City Lord Wu Yan had sent more than one message to Zhao Hua, accusing Gu Jinlai, the Zone Leader under him, of cleansing the Demon Territory and disrupting the fragile balance between the Human Clan and the Devils, triggering a great war.
Zhao Hua was also filled with anger at the time, so as soon as Gu Jinlai returned to the city, he immediately gathered his forces and attacked, intending to teach him a lesson.
He even planned to throw him out directly for Liuhuo City to deal with.
However...
After sending one Martial Saint Sect Yan to his death, Zhao Hua was scared by Gu Jinlai into not daring to act rashly.
Later, as Gu Jinlai was besieged by people including Duanmu Shan, he was forced to flee Wind and Rain City, succumbing to Wu Tianya's deception, and defected to Star Trace Demon God, whom Wu Tianya served.
