After I became a villain master, my beautiful apprentice fell in love with me

[Single female lead + system + dog food + master and apprentice + book travel]
Also known as: The villain master does not turn evil, the beautiful apprentice wants to hug
Su Chen traveled into a novel and became the villain master who turned evil in the later period of the book. It is impossible to turn evil, he wants to live comfortably until the end of his life.
Who knew that he would force the male lead to become a villain, so he killed the male lead and he will be the villain.
System version:
"Lovely pat the head to kill, and say 'Ling'er is so good'."
"Feed with care, and let the beloved apprentice say 'Master feeds so delicious'."
"Domineering wall kiss..."
The tasks issued by the system are getting more and more greasy. His life cannot be controlled by the system, so he decided to do it himself.
