The Three Kingdoms: My Wife is a Great and Good Teacher

Traveling through the chaotic times at the end of the Han Dynasty, Liu Zhaoqing also wanted to be a hero, but unfortunately this was a mythical version of the Three Kingdoms.
Zhao Yun’s spear can penetrate a mountain, Zhang Fei’s roar can shatter a person’s skull, and Lu Fengxian’s halberd can shoot from the camp gate to Jiangdong!
What’s even more terrifying is that they are women!
Fortunately, Liu Zhaoqing has already started a family and has a career. He just wants to live out the rest of his life in peace with his wife and maids in this chaotic world. However... his lovely wife, Zhang Jiao, has been acting a little strange recently.
He often muttered something like "The blue sky is dead... the yellow sky should be established"? ?
