Traveling through the Northern Song Dynasty, Song Zhao became a failed scholar on the streets of Yuncheng, making a living by setting up a stall and writing letters. The chessboard of destiny awakened in his mind, but he saw the death methods of all the 108 generals - gathering Yi, recruiting An, conquering Fangla, and dying, no one was left.
He changed Ruda's life, but the price was that he choked on drinking water for three consecutive days and fell when walking; he saved Lin Chong from disaster, but the price was that he was falsely accused and almost went to jail. Every time he saves a person, the future on the chessboard becomes blurred, and he changes from an omniscient God to a half-blind chess player. What's even more terrible is that there is a person in the dark, holding the "Fragment of the Book of Heaven", a divine artifact from the same source, who can deduce the fate of the country and is locking all heroes on the road to death.
One changes one's life, the other locks one's life. A poor scholar with no power, versus a behind-the-scenes chess player who has controlled Song Jiang for twenty years.
Song Zhao wrote a letter for Song Jiang, but he wrote two more words at the end. Five years later, Song Jiang came to him and asked him what those two words meant.
He said - see for yourself.
