In his previous life, Mu Yuge, the prince of Wangjiang Marquis, mistakenly believed in the "life-saving grace" of Ping'an's concubine Jiang Liyan and insisted on marrying her, but was betrayed. She colluded with the enemy, falsely accused the Hou Mansion of collaborating with the enemy, and caused the entire Mu family to be executed. On the execution ground, the dying 14th prince Xiao Jinyuan told the truth: the person who saved Jiang Pan was actually him. Mu Yuge died with hatred.
When he opened his eyes again, Mu Yuge returned to the night before the marriage proposal. He tore up the marriage contract and swore that he would no longer be a loyal minister and good general, but only wanted to live freely in the world.
Unexpectedly, three days later, Xiao Jamyuan was reborn and returned to Beijing. The two reunited in Yanyu Tower and discovered the secret of each other's rebirth. Mu Yuge said: "In this life, I will lead the horse for you, and you will kill all the thorns for me."
So the prince wrote to set up a situation, and the prince held a sword to judge the crime. They teamed up to expose Jiang Liyan's crime of stealing seals and collaborating with the enemy, thoroughly investigated the conspiracy of Ping'an's Mansion, and finally made the truth known to the court. Jiang Liyan was sentenced to death, and the Hou Mansion was wronged.
However, Mu Yuge refused to accept the title and only wanted to indulge in the mountains and rivers. On a day when the spring breeze was blowing in the willows, Xiao Jingyuan stood on a white horse at the foot of the city. Mu Yuge came with a smile, rode together, and rode off into the sunset.
"In this life, I would rather lose the mountains and rivers than lose you."
