My Sickly Disciple Wants to Usurp His Master

[Two male leads + transmigrate into a book + equally matched leads + scheming yandere + younger man] (The shizun is the one being pursued)

A gentle, aloof, beautiful shizun who is actually proud, fiercely competitive, and battle-crazed, paired with an affectionate, jealous disciple who seems sweet but is actually a yandere with a deceptively innocent facade. [The gong has several clones.]

Tianfeng Wan, a heavenly god, transmigrates into the world of a book. Not only are all his powers sealed, he also has to escort the male lead along the path to becoming the foremost cultivator of the righteous sects.

Since that's the case, he becomes the male lead's shizun, guiding him carefully while taking down scumbags along the way.

But as they spend time together, he realizes there's something wrong with the male lead. Not only does he always cling to him, sometimes he even dares to flirt with him in a way that's downright outrageous!

Male lead: “Shizun, I've told you before that you smell so good, even sweeter than the candied fruit I've had before... I wonder if what's inside tastes even sweeter...”

In the end, he discovers that his handsome little disciple is actually dark inside!

Question: What do you do when you've raised the foremost cultivator of the righteous sects to be evil?

Question: What do you do when you've raised the male lead all wrong?! Help, I need an answer urgently!!

He goes to find a friend in the middle of the night to discuss a solution, only to be caught and dragged back by his own dear disciple.

The male lead angrily grabs him by the chin. “Shizun... do you really like him that much?!”
