Luo Xun is a busy villain. He has to support the good-for-nothing protagonist while constantly courting death in front of him.
In the end, he is supposed to become a world-destroying demon god, be defeated by the protagonist, let the protagonist save all living beings, fulfill his destiny, and ascend to godhood!
But Luo Xun torments the protagonist-disciple into becoming his most devoted hater.
Luo Xun: You're only fit to sweep the sect's mountain.
Protagonist: Master is taking great pains to protect me, knowing that towering trees attract the wind.
Luo Xun tells the sect disciples to ostracize the protagonist.
Protagonist: Master is helping me sever worldly ties. He's helping me cultivate the path of passionlessness.
Luo Xun gives his disciple a pile of weird, shoddy pills, waiting for the protagonist to take the bait.
But the protagonist treasures them too much to eat any, and escapes a calamity.
The protagonist gets beaten black and blue by Luo Xun.
Protagonist: Sect Leader, Peak Masters, I tripped on my own. It has nothing to do with Master.
Luo Xun has no choice but to go even further in courting death. One day, the protagonist gets revenge by imprisoning him as a cultivation furnace. Who knew the disciple would fall into demonic cultivation after draining him?
Luo Xun is baffled. I'm the one who's supposed to turn demonic!
Later, Luo Xun regains the memories of his past life and remembers that the protagonist-disciple was his master in that life.
His master bears Heaven's punishment and despises Luo Xun. In this life, he set up a System scam to make Luo Xun suffer and bring about the world's destruction.
Luo Xun curses the System: Get out, you wretched thing my scumbag master used to deceive me!
System: Host, I really was made by you!
This story begins at the very end. There's a little angst, but not much.
