An accident brings programmer Li Wenjie into contact with an ultrarealistic sandbox System called [Guardians of Huaxia].
The System creates several virtual timelines completely isolated from reality, allowing him to “experience firsthand” pivotal moments that shaped history and make his own choices.
From the upheavals at the end of the Qin dynasty to the Ming dynasty’s desperate struggle for survival, he devises strategies and achieves the “perfect” outcome in one simulation after another. Even his life in the real world takes a turn for the better.
He thinks he is playing a completely safe simulation game, unaware that every time he clicks “Confirm,” he is quietly changing himself as well... Only when the System reveals the final truth does he understand that the cost of this game is far heavier than he ever imagined.
