Modern forensic doctor Lin Weixi, through a carefully calculated "time and space echo technique", traveled through time and became Su Wan, an orphan girl from the Dajing Dynasty who was forced to marry as a substitute. The memory fragments that suddenly appeared in her mind and the warning letters hidden in the secret compartments of her old home came from her previous life - the national master Yunyin who had great power but was betrayed and his entire family was executed.
It turns out that this time travel was never an accident, but a revenge plot across time and space that Yunyin set for himself in this world at the cost of his soul. She carries double memory seals, and every step she takes follows the trajectory of her previous life: poisoning the prime minister at a night banquet, dealing with the sick and weak prince Xiao Jamyan, but while consuming "fate energy", she encounters strange variables.
Seven time and space anchors appeared one after another. The enemy's proton, the king of rivers and lakes, and the abandoned concubine in the cold palace were all hidden chess pieces from the past life, but Jamel Xiao was actually the unrecorded eighth anchor - her reincarnation. When the "sick" prince turned against her and imprisoned her, and when the "Time and Space Management Bureau" that manipulated history emerged behind the court's intrigues, Lin Weixi was shocked to realize that the chess game was far deeper than imagined.
Three identities are intertwined, non-linear time is intertwined, the current life chooses to rewrite the past life, and the layout of the past life leads to the current life. Should he follow his past revenge plan, or should he break fate and become his own chess player? The most terrifying game is always the confrontation between oneself and oneself; the most extreme freedom is to still choose to reshape destiny despite the thousands of layers of layout.
