In the twenty-seventh year of Yongxi's reign, the sixth prince Li Zhao was reduced from a prisoner in the imperial city to a prisoner due to an unfounded arson case. He was demoted to a commoner by his father and sent to Yanmen Pass in the north. Everyone thought this was a desperate situation, but they didn't know that exile was the way to break the situation he had earned with his own hands - smoke was everywhere in the north, and 30,000 Chile cavalry were pressing down on the border. However, he had an intercepted secret message hidden in his arms, and a copper bell left by his mother and concubine hung around his waist. He wanted to tear open the cracks in the conspiracy in the blood and fire of the wall.
On the way to relegation, the Shadowscale Guards chased him, the secrets of the ghost market, and the natural credit contract came one after another. He meets Zhongyong's old subordinate Shen Tang and gets help from the killer Shen Qingyi (actually the eldest son of the emperor Zhao Heng who is hiding under a pseudonym). He even accidentally discovers that the mother-in-law's "suicide" had a hidden secret. The truth about the queen and the prince's affair with a foreign enemy gradually comes to light. From the deadly battle at Luhe Station to the defense of Yanmen Pass, from the fire attack at Heifengkou to the uprising in the imperial palace, Li Zhao used blood as ink and a knife as a pen to write the legend of "relegation is a gift" on the frozen soil of the north - he lost his status as a prince, but won the hearts of the soldiers; he was burdened with the curse of heaven's credit, but he held the key to breaking the situation.
When the bell was broken, the secret passage was opened, and his brother returned, he finally understood: the so-called relegation was the hidden expectation of his father, the protection provided by his mother and concubine, and the starting point for him to break away from the shackles of fate and protect the people of the country.
