The Sick and Weak Demon Lord Is Pampered by Me

The Male Protagonist Is Sick and Weak. He Could Cough up Blood, Faint, Have a Heart Attack, Be Paralyzed, or Anything Else.

I want to read a book like "Although I'm Sick, But I'm Really the Savior". It's best if it's free of CP and can be eaten casually, as it can be life-threatening! ! ! Group favorite!
