The Huaxu Sect has a sword immortal who never draws her sword in a fight.
Mu Jin transmigrates into this notorious show-off. In her first three days in the book, she draws her sword seven times.
Everyone she draws her sword against ascends within three months of their battle.
Word of her sword-drawn ascension spreads far and wide, and the entire cultivation world goes wild.
Seeing a line stretching for miles outside her sect, Mu Jin scrambles back to the rear mountain.
The next day, a recruitment notice appears in the World Mirror:
[Looking for a hired fighter. Meals and lodging included, with an official position. Great pay, little work, and high status. P.S. Only the strongest need apply.]
The ruthless man who doesn't waste words: [No one in this world can match me.]
Overjoyed, Mu Jin coaxes and tricks him into joining the sect, promising to draw her sword and send him ascending in three years.
Three years later, Mu Jin keeps her promise and draws her sword, eager to send him on his way.
The man reveals his true form and cuts down ten thousand swords with a single move. Gritting his teeth, he says, "This time, you're not sending me away."
The Demon Lord Xie Xigui has a special cultivation technique that creates a clone every hundred years.
By the time he finally gathers all seven clones and prepares to make his move, all seven of them have ascended together.
He bursts out of the Demon Abyss with his sword in hand, only to find the culprit conveniently delivered to his door.
Xie Xigui secretly vows not to return to the Demon Abyss until he's killed her.
Three years later.
The people of the Demon Abyss: "Demon Lord, please come back! Marrying into her family is a terrible idea!"
