In the last years of Yonghe's reign, Prince Wei Xuan was framed and collaborated with the enemy, and his entire family was executed. Taifu Wei Heng hanged himself in the palace to prove his innocence. Only his youngest son Wei Shuchen survived. Before his death, Wei Heng entrusted his secretary to the Wen family, a close friend of the imperial merchants. He changed his name to Wen Jizhi and hid in the merchant's home.
After ten years of dormancy, Wen Ji has grown up, appearing as gentle as jade, but inside there is thunder in her heart. He is rational, calm and resourceful. Although he is physically weak, he is willing to take risks and vows to uncover the truth about the unjust case and clear up the shame of his family and the prince.
In the north, Lu Yicheng, the adopted son of the Marquis of Zhenbei, has great military exploits and a straightforward and frivolous temperament. He is actually an orphan from the previous dynasty, and his life experience is a mystery. Destiny caused two people who had no intersection to meet. From opposing positions to not knowing each other without fighting, to sharing life and death, feelings secretly emerged.
The court is once again in turmoil, powerful ministers are in power, and old cases are as hard to solve as icebergs. Wen Jizhi used the Wen family's business network as a cover to set up a chess game, while Lu Yicheng used military power as the backing to protect him. The two join forces to fight their way through intrigue and betrayal.
