[Double male protagonists + HE + dual purity + master and slave + dual powerful plots + etiquette and taboos + extreme restraint + forbearance and affection] The young emperor Xie Heng is cold and taciturn, decisive in killing. He ascended the throne at the age of sixteen. He has powerful ministers inside and powerful enemies outside. Shen Qingci, the protégé of Southern Chu, was as gentle as jade and had no plans to leave behind. He came to Beijing at the age of eighteen and worked every step of the way, just to protect his homeland. They are natural rivals. They use the world as a chessboard and the country as a bet. They plot against each other and check and balance each other. They are also the only confidants, supporting each other and supporting each other in the darkest moments. When the palace changed, he stood in front of him and sealed his throat with a sword. On the road to exile, he was separated by three thousand miles of mountains and rivers, clearing all obstacles for him. On the top of Mount Tai, thousands of people were worshiping him, but he accidentally stepped on the hem of his clothes. Next to the imperial mausoleum, he erected a wordless stone tablet for him. Everyone in the civil and military circles of the dynasty knows that His Majesty and the Prime Minister are wise kings and wise prime ministers who are rare in the ages. Together they put down civil strife, unified the world, and created a century of prosperity. They have been kings and ministers all their lives and have followed the rules all their lives. No one knows what kind of unspeakable secret is hidden in those two tombs standing side by side.
