The arena is a chess game, and everyone is a chess piece. The Black Iron Alliance in the north, the Yanyu Tower in the south, and the Burning Heaven Palace in the west are three pillars of the alliance, fighting endlessly.
Su Jingchen, the master of Zangfeng Pavilion, wants to use business as a blade and hide his edge in a sheath to end this troubled world.
His younger sister, Su Qinghuan, has a pair of plain hands that can revive the dead and poison all living beings. She was originally a lazy spectator outside the chess game, but she made a plan for her brother and bought back the sharpest knife from the most mysterious "Night Walk" in the world.
His name is "Zero". He has no past and no future. The only meaning of existence is obedience.
When the most unruly soul meets the coldest weapon, the chess piece she casually dropped becomes her only variable and weakness.
She taught him to see clearly the evil deeds in people's hearts, and he shielded her from open and hidden arrows.
In this huge gamble with the world at stake, she had calculated everything except that the sharp blade that stained her with wind and frost would actually point to her own heart.
Purpose: Taking the chess game in the troubled times as the background, it tells the story of the companionship and secret love between the chess player and the killer chess piece, breaks the plan and fate, and explores the awakening of human nature, the pros and cons of power, and the incalculable core of the heart.
