The Treasure Kiln

The general and his son are all circling around; it's obviously doomed. I'm abandoning the story.

The female protagonist transmigrates into the body of an abandoned wife. While recovering from childbirth, she discovers she possesses a space within a clay kiln, containing military strategies and formations. Due to her ex-husband's malicious harassment, she encounters the male supporting character Yu and the male protagonist Chen, who help her out. Later, she uses her space to save Chen's life.

It drags on and on, just describing that trivial matter.
