Jiang Ye, a new recruit, took a dead man's quota at the recruitment office and was sent to the Ash Star to mine. Ten years later, he became the most inconspicuous accountant in the Munitions Department - handling three thousand accounts, and everyone regarded him as a soft persimmon who set the abacus.
But no one knew that he was not calculating the score.
Buried under the Ashes Star are the ashes left by the burning of a chess game three hundred years ago; in the shipyard to the south, there is a broken ship that recognizes its owner; the ship-eating wall in the Unconfused Star Zone is the chessboard left by the shipbuilder. The seventh ship has fed the shipbuilders a three-hundred-year wall, and every shipload of mines fed into it is a piece that falls on the chessboard.
The wall is the chessboard, the account is the chess record, and the key is a ship pretending to be dead.
Jiang Ye held the account book with only the word "accept" written on the last page, and decided to take away this three-hundred-year chess game on behalf of the shipbuilder.
At the end of the chess game, the winner has to take the chessboard away for the loser.
