Lin Muhan transmigrates into a poorly written cultivation novel called The Path to Enlightenment Through Purple Qi, as a cannon-fodder character, one of the five peak masters of Tianyan Sect. The Peak Master Lin, who shares his name, is cold and merciless, with severe OCD. He demands perfection from himself and only takes on attractive disciples. But after accepting Xiao Yuexian as his disciple, he starts looking down on the boy's talent compared to the male lead, who is apprenticed to his senior brother, and treats his own disciple with harshness and cold indifference.
The unloved young disciple falls for the male lead as he grows up. Rejected after confessing, he turns evil and becomes the story's first major villain. He kills his master, murders the male and female leads, and destroys the world.
How could such a sweet little thing turn evil? Impossible! As long as he raises him properly...
What? Breaking character comes with a weakness debuff? Fine, he'll get a few more secret identities.
Huh? Why has my disciple still turned evil? Wasn't he supposed to be the male lead's future harem member? Why is he building his own harem and adding his benefactor, friends, and brothers to it, then making his master his sex slave? Good disciple, how about only collecting your master's secret identities?
