Everyone in Qingyun Sect knows that their junior apprentice, Mu Qinghe, has a crush on his second senior sister and is always at odds with his eldest senior brother, Lin Qingfeng. He secretly hides Lin's notes and deliberately interrupts his conversations, acting like an immature child. No one knows that behind Mu Qinghe's "targeting" lies the System's cold warning: "Host is the destined villain. You must sabotage the male lead Lin Qingfeng's opportunities, or the backlash of demonic energy will kill you within seven days."
He'd planned to follow the System's instructions and keep his head down to survive, but his feelings became confused as he grew closer to Lin Qingfeng. Lin seemed aloof, yet patiently guided him whenever he made mistakes in his cultivation. When Mu Qinghe was overcome by a demonic affliction, Lin protected him with the power of his true dragon bloodline. Even after Mu Qinghe's demonic identity was exposed and a kill order was issued, Lin still protected him.
Watching the two of them together, the System assigned him a mission to kill Lin Qingfeng. But he refused, even breaking free of its control for Lin's sake.
From then on, the cultivation world lost a pair of paragons of the righteous path, hailed as a match made in heaven, and gained a unique pair of cultivator partners who joined hands to resolve the conflict between humans and demons.
