Shen Yichen, a young genius, became famous after playing in a street chess hall when he was 14 years old. With his powerful chess style of slaying dragons in every game, he quickly emerged as a bright new star in the Chinese Go world. Facing Japan's six top players, he traveled east to stir up the chess world, winning his first world championship and becoming the only player in the world in the 1990s. However, as AlphaGo swept across the Go world and defeated Li Shishi and Ke Jie, human chess players fell into a trough. Shen Yichen, who has been retired for many years, chooses to come back and start a peak showdown with AI - a five-game battle. Will human wisdom win, or will cold calculation control the future? On the chessboard, the outcome is uncertain, and the legend returns!
