Martial King's Retired Life - Chapter 11Book 15:

I, Seiren Shikino grew up in an orphanage. On the day of my high school graduation, I somehow got transported to another world, and turned into a girl as well. ……Eh, this isn’t my original world and gender, right!? It seems that I’m now Seiren, the daughter of a noble from another world. This is a light hearted story about family and romance.

Amidst a disaster, an orphan contracts a sickness.

“Welcome to Perfect Life Simulator!”

“You can choose to simulate your own life or someone else’s life to find solutions to many life problems!”

…

A watch handed down from his deceased parents allowed Su Wu to start a future life simulator.

He thought that he could really use this simulator to lead a perfect life without regrets, but unexpectedly things developed in another direction.

In the future, as long as there is light, there will be evil spirits that kill people;

Hanging in the sky and covering a city, it leaves a city without red lanterns of living people;

The scarlet eye that can use a mobile phone to spy on the specific location of others…

Will such a future really come?

…

“you are dead.”

“This simulation is over.”
