Life Simulator: Make the Female Demon Regret Her Life

[Rating just released, will rise further] "Life simulation" + "Reality alteration" + "All heroines included" + "Main heroine is brand new, some secondary heroines are not new"

[In your first simulation, you've been transported to a world of cultivation.]

You become an alchemy disciple. In a mountain cave, you first encounter a female demon. You refine elixirs for her, restoring her to her peak condition, and in return, she bestows upon you a great fortune.

[In a great battle, a wisp of your true dragon energy awakened a dragon that had been dormant for 100,000 years, saving her life.]

When the simulation ended, you died, while the female demon, carrying a crystal coffin, stormed into the Ninth Heaven...

...

[In the second simulation, you've traveled to the world of Zhenwu.]

She was the Empress of the Great Yan Empire, and you were a strategist from an enemy state. After your defeat, you were captured and subjected to all sorts of humiliation.

Seeing the jade pendant on her, you mistook her for your long-lost younger sister, but in reality, your sister had become one of your female generals...

In the end, your younger sister rebelled, and you died protecting the Empress. After the Empress was reborn, she and your younger sister came to find you...

...

Countless simulations, with regrets, disappointments, and gains...

However, what they regretted for the rest of their lives was... how could Su Fan be so philandering!?
