Eleven years ago, General Shen Chongyuan of the Northern Guard was falsely accused of "having an affair with Beidi and plotting to seize the imperial city", and his whole family was convicted. All members of the Shen family died in battles on the border or were taken to the execution ground. Shen Qingxian, who was only eight years old, was desperately rescued by his father's bodyguards. He lived incognito and wandered around the world.
