“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.”

She is a top-class spy, a poison specialist, but also a young and cute girl with a sinister temperament. In spite of her sweet and innocent appearance, she can complete any tasks without the slightest hesitation. One day because of an incomplete black magic, she was sent into the body of a girl who was deemed as a good-for-nothing. What kind of change will she bring to this continent?

Her rebirth gave her a second chance at life. She was back with a vengeance and wanted to make those that had harmed her pay. But to those that helped her, she wanted to repay them. Her evil stepmother? She would slowly pull out her claws, one by one. Her evil stepsister? She would crush her pride. She thought that by getting her revenge for her past life, she would be happy in this life. However, she never would have thought that danger would chance upon her time and time again. The hatred from her clan and whether their bloodline would continue to exist, lay solely on her shoulders. Luckily, on this thorny path, someone had always been protecting her. “Third Prince, have you ever regretted being with me?” That person laughed lightly and peered at her with a loving yet weary look, “As long as I am together with you, I have no regrets.”
