Seventeen-year-old Yun Tianche just wants to be an ordinary high school student. However, in the old bookstore left by his grandfather, a piece of warm ancient jade broke his peaceful life - he was the successor of the "Blue Dragon Chess Soul" that sealed the passage to the Three Realms five hundred years ago. The blond girl Elena descended from the sky, claiming to be his Greek cousin, and was ordered to take him into the "Tianji Pavilion" to practice chess. Here, the duel is not a battle, but a "chess game": there is no attack power and health, only the flow of "luck"; the battlefield is the Nine Palaces Bagua disk integrated with Qimen Dunjia; every hexagram card has yin and yang sides, and every choice accumulates karma. When masters compete, the arrangement of cards itself is a poem, a word, an allusion - this is "contextual resonance". The Guixu Cult is stirring in the dark. They believe that "nothingness is liberation" and attempt to gather five chess souls to return all realms to zero. Yun Tianche's mother disappeared eight years ago and is being imprisoned deep within the cult. From the tragic defeat, he realized that "losing is the first step to becoming strong", and from "not fighting", he realized that "the way follows nature" - what Yun Tianche must learn is not only how to win, but also how to bring the opposing "powers" into harmony. The work integrates the hexagrams of the Book of Changes, the Five Elements, various schools of thought, poetry, and songs, and uses original rules such as "luck roulette," "Bagua array," "law of cause and effect," and "contextual resonance" to build an unprecedented card duel universe. This work spans ancient and modern times, China and foreign countries, and tells an epic story about destiny, choice, inheritance and reconciliation. The game is not about winning, but about following the path. The real chess player is not to conquer the opponent, but to harmonize the "power" of both parties.
