A bullet sent his soul away for a thousand years; an imperial edict sentenced him to eternal damnation.
Luo Yi, a modern anti-narcotics police officer, died heroically in the mission, but his soul fell into the eye of the storm in the 17th year of Zhenguan in the Tang Dynasty - becoming the deposed prince Li Chengqian who had just failed in his rebellion and was sentenced to death by the emperor's father Li Shimin! The blade of the sword reaches his throat, poison enters his heart, and murderous intent is everywhere inside and outside the court.
In ten days of longevity, two souls will live together. The overwhelming hatred and broken memories of the original owner remain in his body, and before him is a shocking killing scene that has not been recorded in history books. The gentle and gentle King of Wei, Li Tai, laid out a series of poisonous schemes: cutting off the heart of Gelsemium for seven days, constructing irrefutable evidence of rebellion, manipulating the heroes of Lingyan Pavilion, and even using the emperor's blade to cleanse all the insiders! At every step, he wanted to nail "Li Chengqian" to the pillar of shame, leaving no trace of his body.
Modern criminal investigation VS Tang Dynasty conspiracy! Luo Yi used toxicological analysis to identify the real culprit, used the scar code to decipher the mutiny code, and used handwriting identification to uncover the perjury. When Li Tai revealed a murderous weapon that spanned time and space, when Emperor Li Shimin's heart was as deep as the abyss, when the consciousness of the original owner in his body laughed wildly, "You will pay the debt of Gu"... Luo Yi could only rely on his life, and in the ten-day countdown, set off an ultimate showdown in the Tai Chi Palace that would tear the curtain of the prosperous age!
Is he a stranger who has borrowed his corpse to return to life? Or the crown prince reborn from the ashes? Behind the truth, where the smoke is filled, there is a greater shadow that stirs up the fate of the Tang Dynasty...
