Su Yu transmigrates into the interstellar Beast World as an F-rank female deemed useless by her family, who sells her to the Northern Border general, on the verge of turning feral, as a good-luck bride.
A livestream accidentally starts on their wedding night, and the entire interstellar world watches, expecting "the mad general to tear his mentally disabled bride apart."
Instead, Su Yu raises a hand and massages his Zhong Ting acupoint. The rampaging SSS-rank beastman instantly goes quiet as a mouse.
The Star Network explodes, the Su family is dumbfounded, and the Council of Elders grows uneasy.
They don't know that Su Yu has an entire vault of human civilization's knowledge in her mind.
Composting is ancient agricultural wisdom, massage is traditional Chinese acupressure, Chinese characters are barrier spells, and the solar terms are rituals for restoring a planet's origins.
She thinks she's livestreaming farming and teaching common knowledge, but every swing of her hoe is digging at the Council of Elders' lifeline.
A monopoly on purification agents? Try calming grass.
Pollution in the mental sea? Practice the Five-Animal Exercises.
A depleted planetary core? Perform the solar-term ritual.
An insectoid prince disguises himself as a merchant to steal seeds, a genius botanist blocks her door begging for a research paper, and the Imperial military lines up to present her with banners of honor.
And one night, the Silver Wolf general, as cold as the Northern Border winds, corners her on the ridge between the fields:
"You healed my mental sea."
"So?"
"So my life belongs to you now."
One-on-one romance, marriage before love, farming and development, livestream face-slapping, civilization-level technological superiority, no harem, no suffering for the protagonist, and all the races of the interstellar world come to pay their respects.
