Zhao Yelan was born as a criminal s*ave and was rescued by the Third Prince. After years of painstaking efforts to put him on the throne, Zhao Yelan became a sycophantic minister whom everyone detested, but he was actually given a marriage by that person to general Yan Mingting, the lone star of Tiansha.

The general caused the death of his father, his mother, his wife, and his dog. Everyone hoped that the general would kill Zhao Yelan as soon as possible.

On the wedding night, Zhao Yelan, who was dressed in red, took out a dagger, his eyes sharp: “What do you want?”

Yan Mingting held his hand tightly, and borrowed his dagger to carve a large character on the head of the bed – – Early.

“You’re weak and frail, get up early every day and practice horse stance with me!”

“?”

The common people thought this marriage was truly wonderful!

They heard that this big minister was beaten every day. He had to repair the roof tiles when the house leaked and also work in the kitchen. He served his husband and was very obedient, and from then on, he didn’t dare condemn people.

Hey, the general was truly mighty!

Zhao Yelan sat lazily by the bed, playing with the dagger, and raised the ends of his eyes slightly: “Where did these rumors come from?”

“From my dog’s mouth.” Yan Mingting, who was in horse stance, patted his thigh. “Madam, please take the seat of honor. You don’t have to get up early tomorrow.”
