Fighting with Oneself as a Chess Piece

Destiny is given by heaven, and people are destined to cultivate it. Destiny always opens a chess game for you inadvertently. Dayan's number is fifty, Tianyan's is forty-nine, leaving a thin line for others to fight for. If you win, it's luck, but if you don't, it's fate. And I just want to use myself as a chess piece to fight for this chance of survival.
