Zhan Ling's greatest mistake in life was suffering from a lack of education. She had not entered the Dihua Ability Institute for further study. Instead, she had thirsted intensely for power and authority. By chance, she came into contact with the "cult" scattered throughout the world in various dark corners, and that was where her mistake began.
Because of Zhan Ling's unique nature and talent, she received a personal audience with Luo Zhong.
He was not only willing to provide Zhan Ling with a special evil cultivation technique, but also bestowed upon her a team of a hundred people, helping her secure a sufficiently high position within the Dark Forces.
In return, once Zhan Ling reached a certain height, she would have to provide the "cult" with all kinds of assistance.
To ensure that Zhan Ling would not go back on the agreement midway, she had to be subjected to "gu poisoning" beforehand.
Without relying on the shortcut provided by the "cult," Zhan Ling might have needed another ten or even twenty years to reach the heights she eventually attained, and the process would have been extremely dangerous as well... Therefore, Zhan Ling ultimately agreed to this "deal."
Luo Zhong personally planted a Soul Gu deep within Zhan Ling's soul.
Once she accepted the gu, no one and no method besides Luo Zhong could remove the Soul Gu from her body.
It was only after Zhan Ling gradually climbed to the peak of the Dark Forces that she began to realize the magnitude of the mistake she had made and slowly saw through Luo Zhong's true nature.
This man could not be described as merely "evil" or "wicked." He was an outright heretical existence—anti-human and antisocial. In Luo Zhong's eyes, the entire world was nothing more than his personal "feed."
