Qin Chuan transmigrates to a fantasy world and becomes the young master of a cultivation clan. But on the day of his wedding, demonic cultivators invade. With mediocre talent, he works hard at cultivation for decades and still gets nowhere.
During another great battle between the righteous and demonic factions, he unexpectedly obtains a demonic inheritance and awakens the Yin-Yang Reversal System.
But the System vanishes almost as soon as it appears, leaving him with only a few minor benefits.
Sixty years later, Qin Chuan emerges from seclusion with his demonic arts perfected, only to run into Ye Ningshuang, who nearly married him all those years ago.
After a fierce battle, Qin Chuan is outmatched and taken back to the Listening Tide Sword Pavilion. Then something strange happens: nearly every disciple wants Qin Chuan to beat them up.
Qin Chuan: I'm a poison cultivator! Aren't you righteous cultivators afraid of poison?!
Listening Tide Sword Pavilion: What poison? This is amazing!
Heavenly Sword Tower: Divine Healer! Save me! Please, save me!
Demon Beast Sect: What do you mean, a poison core? This is a heavenly-grade healing medicine!
Qin Chuan: No! I'm really a poison cultivator!
