He Has a Sickness that Needs to be Cured Novel

Sentenced to missions across various worlds for a past transgression, Xi Ning's task is to correct plot-altering anomalies. His assignments involve individuals such as a non-existent character, a supporting character experiencing a breakdown, or a villain who eliminated the protagonist.

Fortunately, each world offers an "antidote" to alleviate his condition. Xi Ning, guided by the principle of utilizing all tools, finds the narrative unexpectedly shifting.

A dangerous vampire threatens a sickly youth, demanding a bite. The usually silent mermaid bargains with a pirate leader, offering a song for cake. And a depressed elf clings to a dark magician, begging him not to leave.
