At eighteen years old, Lin Qingyu was married as part of a Chong Xi into the Nan’an Hou Mansion, becoming the ill Lu Wancheng’s male wife.

On the eve of their wedding, Young Master Hou lay lazily on the bed and said, “Beauty, to be honest, I really don’t want to engage in domestic struggles. I just want to drift along, eat and wait to die. I want to be a salted fish.”

A year later, Young Master Hou became gravely ill. He took Lin Qingyu’s hand and sighed, “Wife, I’m going to die, but I think I can continue to transmigrate. In order for you to properly recognize me in the future, let us set a secret code.”

After the death of Young Master Hou, Lin Qingyu was prepared to stay a widow all his life. Unexpectedly, after only half a year, the great general who had rendered outstanding military service, actually came to propose marriage.

Lin Qingyu would rather die. But the general said but one statement, “If odd, change; if even, remain the same?”

Lin Qingyu: “…I will marry you.”

After two years, the general died in battle. Before Lin Qingyu even had time to grieve, he was recruited into the palace by the Emperor.

The emperor complained aggrievedly, “Baobei, this time I have became the Emperor. My salted fish dreams have been completely shattered…”

Lin Qingyu knew that although his husband was a bag of lazybones, no one was his equal when it came to conspiracy and schemes.

He rubbed the Emperor’s head. “Don’t think about it. Get started on those reports. Behave yourself.”
