Ten years ago, young Lu Jinghan rescued Shen Qingci from dying at a mass burial site in the wilderness. Their fate was bound together for ten years.
Lu Jinghan, the former war god of the country, was charged with treason and returned to Beijing covered in blood. Officials throughout the dynasty rushed to step on him, and the second prince secretly set up a trap. Everyone tried to avoid him, and every word was to put him to death.
In the midst of the scolding, Grand Tutor Shen Qingci, who had been lingering on the hospital bed all year round and coughed until he lost strength at the slightest movement, stepped forward with his thin body and tried to protect Lu Jinghan in order to save his life. The courtiers all sneered secretly, concluding that he wanted to treat the criminals harshly to please the royal family.
No one saw through his disguise. Shen Qingci was cold and distant in front of others, but secretly swept away the assassinations and suppressed the rumors. Even if he coughed up blood and hurt himself, he would still protect Lu Jinghan from all the open and secret arrows. After ten years of bedridden illness, he had been waiting for only this person.
Lu Jinghan was proud and wary at first, but when he was faced with desperate situations again and again, his hard heart gradually softened. Frauds and tortures followed one after another, and the dusty past came to light: the destruction of the Shen family and the disastrous defeat of the Northern Territory were all a conspiracy by the emperor to check and balance.
In a desperate situation, the two of them took off their disguises. The despised general is a good general who betrays his loyalty and secretly investigates the case; the sick minister who is despised by everyone is the chess player who has been planning for many years and controls the court.
The whole world wanted to break them up, but when they first met when they were young, the two of them were destined to share the same fate. One civil servant and one military officer join forces to eliminate the traitorous party, and the palace walls confront each other. How can they tear apart the ten-year-old shocking scam laid by the emperor?
