The Straight-Laced Senior Brother Gets Stolen Kisses Every Night from His Villainous Junior Brother

[Two male leads + transmigrate into a book and cultivate immortality + a touch of ensemble cast + many foreshadowed clues + younger shidi and older shixiong + fake death trope + redemption and growth + both pure + secondary couple]

A genius talisman cultivator, straight-laced shixiong bottom x a beautiful little shidi who appears obedient but is cautious and suspicious at heart, a Teng Snake top

After the illustrator Xue Zui dies suddenly, he learns that he was originally the grand shixiong to the protagonist top, protagonist bottom, and villain in a novel about two men.

The System says that in the novel, both the protagonist top and the villain fall for the protagonist bottom. After the protagonist bottom dies, they turn against each other, leading to their mutual destruction.

His mission is to change the disastrous ending in which everyone dies.

Xue Zui: "Easy. I'll just pursue the beautiful villain, right?"

System: "The villain is a man!"

Xue Zui: "Never mind, I'm straight. Time for Plan B."

Plan B is to stick close to the villain and make sure he doesn't fall for the protagonist bottom.

So Xue Zui eats and sleeps with the villain, gives him gifts, stands up for him, and even lends a hand when the snake's mating season comes around.

The villainous little shidi: "Shixiong must like me."

In his imagination, he goes from wary and suspicious to gradually accepting it.

Xue Zui is stunned: "We're just brothers!"

Rejected, the villain turns into a gloomy, manipulative flirt and desperately begs for love.

Later, Xue Zui fakes his death to save the protagonist bottom. When he returns, his identity is exposed, and the now-dark and obsessive villain locks him in his bedchamber.

The villain clutches him and weeps in grievance: "Shixiong, please don't leave me again..."

Everyone in the cultivation world says talisman cultivators are good-for-nothings, until Xue Zui picks up his brush and draws an assault rifle, a rocket launcher, and a cannon.

Xue Zui: "Shh, quiet. I'm about to show off."
