Shen Qingci died in the flying snow because of the poisonous wine given by Xiao Jinyuan, the emperor he had loyal to for his whole life. Just because his favored ministers betrayed him, the emperor believed that he was colluding with the enemy and treason.
When he opened his eyes again, he was reborn and returned to the year before his death. He was still the commander of the royal guards, and Xiao Jinyuan was still the cold and fierce emperor. In this life, he put aside his sincerity and only wanted to investigate the unjust cases in his previous life, protect his people, and stay away from Xiao Jinyuan to save his life.
But he gradually discovered that Xiao Jinyuan had changed - he would sacrifice his life to protect him when he was assassinated, would quietly send him a warm stove when he was on duty at cold nights, and would even protect him immediately when his favorites provoked him.
When Shen Qingci was confused, he didn't know that Xiao Jinyuan also had a secret. When the hypocritical courtiers and the green tea nobles jumped around one after another, Xiao Jinyuan's "cruelty" was all directed at the enemy, leaving only tenderness for Shen Qingci.
On the road to rebirth and revenge, the two went from testing each other to fighting side by side, only to realize that there was a bigger conspiracy hidden behind the misunderstanding in their previous lives...
