Chen Du is a modern forensic doctor. His younger brother died in a "hit and run" three years ago. The murderer is still at large.
Late one night, his phone suddenly lit up with a message: "Want to overturn the case for your brother? Help history overturn the case first."
The next second, the world was spinning - he had traveled through time.
Southern Song Dynasty, Shaoxing eleventh year. In Dali Temple, Chen Du was promoted to official.
Qin Hui threw a case file in front of him: "Yue Fei conspired to rebel and will be sentenced to death within three days."
Chen Du opened the case file - the evidence was all forged, the witnesses were tortured to extract confessions, and even Yue Fei's nails were pulled out.
This is not a trial, this is political murder.
But behind Qin Hui was the emperor, and the emperor didn't want Yue Fei to live.
Chendu only has three days. Three days later, either Yue Fei will die or he will die.
He used modern forensic knowledge to conduct autopsies, identifications, and find flaws, and he battled wits and courage with Qin Hui in the Dali Temple, which was full of informants.
But when he finally got the evidence, he discovered that history could not be changed if he wanted to.
The Yue Fei case is just the beginning.
Yuan Chonghuan, Lan Yu, Han Xin... One after another eternal injustices are waiting for him.
The "historical correction value" on his mobile phone told him: Every time he turns over a case, he will be one step closer to the truth about his brother.
But is the person waiting for him in the gap of time really his brother?
