An accident brought programmer Li Wenjie into contact with a surreal sandbox system called "Guardian of China".
The system constructed several virtual time and spaces for him that were completely isolated from reality, allowing him to "experience" the key nodes that determine the direction of history and make his own choices.
From the changes in the late Qin Dynasty to the critical life and death in the late Ming Dynasty, he strategized and achieved the "most perfect" ending in repeated deductions, and even his real life also ushered in a turning point.
He thought he was just playing an absolutely safe simulation game, but he didn't realize that every time he clicked "Confirm", he was quietly changing himself... It wasn't until the system revealed the final truth that he realized that the price of this game was far heavier than he imagined.
