The Beloved Six-Year-Old Lucky Star

Xu Yan'an, a twenty-first-century genius girl, transmigrated with a System space into the eldest daughter-in-law of the Xu family's eldest branch in Anyang Village.

Xu Yan'an was very glad she had been born into this era as a baby. She had now spent more than six years in the Xu family, and it was time for her to shine.

With the System space, Xu Yan'an began making a fortune by gathering and selling medicinal herbs, cooking delicious food, building a new house, and opening a restaurant.

Sometimes Xu Yan'an also had to deal with the troublesome love interests who pursued her brothers. Once they came of age, she had to worry about their marriages, too.

The System space needed Xu Yan'an's experience points to level up, so every day she fretted over earning money and saving lives.

Come on, read these four points below first, then we'll get to the blurb. This book is also titled The Tsundere System Makes Me Save the World.

This is another beloved farm-family story, mainly about the Xu family's rise to prosperity and the ups and downs between the siblings. (It's a familiar old trope, so please don't complain if it's not your thing.)

Since this is a transmigration story, I don't want to hear complaints that it doesn't make sense. The heroine has a twenty-year-old soul in a six-year-old body, so why expect logic?

The heroine has no romance plot, though she may have a childhood friend. There may be bonus chapters later.

The little System takes the form of a tsundere young boy, while the space levels up by accumulating experience points. (Do good deeds and make money.)
