Lu Yichen, the youngest chess master in the world, is known for his calmness and wisdom. He accidentally awakened the power of "playing the sky", and every time he made a move, he could deduce the future. Xuan Mingzi, the elder of the Immortal Sect, appears to be highly virtuous and respectable, but in fact, he secretly controls the chess game, tampering with the secrets of heaven, and using all living beings as pawns to seek immortality. In a public chess game, Lu Yichen revealed the ironclad evidence that Xuan Mingzi had tampered with the secret of heaven using a three-piece layout, which shocked the world of cultivation. Xuan Mingzi became angry and launched a pursuit. Lu Yichen relied on his deduction ability to work step by step in a desperate situation, using chess theory to break formations and people's hearts to break power, and finally killed Xuan Mingzi in the chess game of life and death, and brought clarity to the world. The whole book uses chess as the blade and wit as the bone, showing the unique edge of rationality and the game of destiny in calm and cool writing.
