He is Xiao Ce, the God of War of Dayin. He has protected Xiao Heng for twenty years, from a swaddling baby to a young emperor. The arrow wound on his chest is a medal, and the peace charm around his waist is an obsession.
But when Yanmen returned home in triumph, what awaited him was not the ceremony and music, but false evidence of collaborating with the enemy, a royal staff attached to his body, and a broken gun pierced into the chest by Xiao Heng himself. "Your Majesty, your uncle is so great, I can't keep you." The last thing he saw before his death was the young man who used to cling to him for the peace charm. There was only cold suspicion in his eyes.
Xiao Heng thought that the hidden danger had been eliminated, but he was gnawed by regret for countless late nights. Until Yanmenguan met Su Qingyan by chance - that sickly scholar whose facial features were eighty-nine similar to Xiao Ce's. He felt like he had found a treasure and imprisoned him beside him, forcing him to wear old armor and imitate old shadows to be a substitute for his regrets.
But a shadow is a shadow after all. Su Qingyan's cold demeanor and the freedom in the sound of the bamboo flute are completely different from Xiao Ce. When the conspiracy struck again, Xiao Heng was swayed by suspicion and once again raised the blood-stained broken gun and pierced the double's chest.
"You personally killed two people who were sincerely interested in you." When Su Qingyan fell, she threw the peace charm stained with the blood of the two people at him.
From then on, Xiao Heng became a loner. He dethroned the throne and guarded the solitary tomb. In the wind and snow of Yanmen Pass, he held the broken gun and the remaining talisman, and repented every day. Red plum blossoms covered the tombstones. He spent the rest of his life atonement for the two withered bones, but in the end he could not get back the words "Uncle Emperor" and "Qing Yan".
This is an emperor's self-destruction, a lifelong sacrifice paid for with two lifetimes of affection and two lives.
