After Becoming a Cannon Fodder

After Chang Hao is betrayed, he unexpectedly binds to a System and travels through various worlds to live out the lives of cannon fodder characters.

Cultivation World:

The original host spent his entire life as a pawn controlled by others. His sect was destroyed, he was forced to pretend to be someone's lover, and he endured insults and abuse from the people around them before dying without ever learning the truth.

After transmigrating, Chang Hao ruins his enemy's prospects and reputation, deals with the demon who manipulated others, kills the mastermind, and ascends to immortality.

ABO World:

The original host was married to someone for ten years, spending all ten years slavishly devoted to them. Even after learning that his spouse was using his money to support a mistress and had brought her home, he had no choice but to silently endure it for the sake of their child.

Then he discovers the child isn't his.

After his spouse and the mistress join forces to take his company, they sell him to a brothel and call in his former business rival to humiliate him.

Interstellar World:

The original host rescued a boy from the black market. Feeling sorry for him, he adopted him.

He never expected the boy to spread rumors behind his back and impersonate him to commit crimes, ruining his reputation and turning all his friends and family against him.

Even after destroying the original host's social circle, the boy still didn't stop. He drugged him, hired people to beat him until he was permanently disabled, and made sure that for the rest of his life, he could only live like a dog, dependent on the boy.
