Ji Jin is a doctor who died suddenly due to overwork.
Then he bound the system and entered a book. The system asked him to save the world.
"I know that the host is very determined and has a strong desire to survive. As a doctor, rescuing the wounded and saving the world are also your strengths." The system was complacent with its own vision.
Then, as you wish.
So
The system is reading and Ji Jin is eating;
The system is decrypting and Ji Jin is sleeping;
The system was studying ways to deal with the demons, and Ji Jin got up from the bed with the demon king.
System:…
System: "Labour and management don't care, save the world and love whoever you want."
A few years later, the small world was peaceful. The first thing a demon said when meeting a human was: Have you had lunch?
Motto: Work hard and take care of your health
