Dragon Prince Yuan - Chapter 2 Genesis Runes

On that fateful day, a voice in the sky told everyone on Earth that the world they called home has just been part of some sort of simulation.

In a world where reality shifts with every roll of the dice, a man daily partakes in an extraordinary game with the gods, his actions dictated by his decisions and the face of the dice. He takes great joy in this game until the tables turn, and he himself becomes a piece on the game board. Now, the dice are in his hands, and it’s his turn to shape his own destiny. It’s time for the Snowman to play his part.

Jiang Pengji got something called the Court Intrigue Stream System.

Jiang Pengji: “Okay, System. No problem!”
Years later, she met the target by becoming the most prestigious woman (the Empress).
Jiang Pengji: “Well done, no?”
