After Xi Shiyu dies, he transmigrates into a cultivation novel as the sinister villain's... master.
The System promises that if he raises the villain into an even more vicious world-destroying demon than in the original story, it will let him live freely in this world.
But when Xi Shiyu looks at the young villain before him, who does nothing all day but sleep and read storybooks, he can't help feeling that something is off.
Until one day, Xi Shiyu casually remarks, "This rain is heavier than the day Yiping went home to ask for money."
Someone behind him quietly adds, "This rain is heavier than the day Consort Qi was beaten to death."
Xi Shiyu: !!!?
His target is another transmigrator!
Well, that makes things easy.
You can burn, kill, rob, and do every evil deed imaginable, becoming the villainous big shot who terrorizes the region,
while I follow behind and sip a little of that freedom,
so what's not to like?!
One lazy fish: Thanks for asking. I'm slacking off.
His fellow countryman is useless, impossible to shape. He won't cultivate or face-slap the protagonist, and despite being a domineering dragon-born hero with a mountain of gold and silver, he spends every day eating, drinking, and waiting to die.
In a fit of rage, Xi Shiyu...!
Exchanges with the System for a body identical to the villain's, then controls it to follow the plot.
He follows the villain's plot while also playing out his own cannon-fodder story. He works hard every moment of every day, earning the title of workaholic from his lazy fellow countryman.
Xi Shiyu: ...Get lost!
At last, when the mission is complete, Xi Shiyu, who has kept his accomplishments hidden, leaves all the wealth he has accumulated over the years to his disciple and fakes his death as instructed by the System.
Two years later...
He leaves his secluded mountain forest and discovers that the world outside has completely changed!
Demons run rampant, the righteous sects have fallen into decline, and the Three Thousand Realms have fallen into demonic hands!
...The Demon Lord's name sounds so familiar.
Isn't that his lazy disciple!!!
When they meet again, the lazy fish who could barely roll over without getting salt on himself two years ago is now wrapped in killing intent, his eyes blood-red, showing all the signs of demonic possession.
He stares at Xi Shiyu, angry and laughing at once:
"I knew you weren't dead, Xiao Yu."
Xi Shiyu: ...Do you have any idea what it means to respect your master? Is "Xiao Yu" really what you should call me?!
