In the first year of the Zhenguan era, the aftermath of the Xuanwu Gate Incident had yet to settle, though the realm was newly at peace. Lu Yan, an eighteen-year-old refugee, transmigrates to Danyang, Runzhou, carrying a virtual encyclopedia and a Technology Tree Unlock System. He begins his rise in the flourishing Tang dynasty, a land in need of rebuilding. His father, Lu Dachuan, has a lame leg but extraordinary strength. His mother, Madam Zhou, uses her modern weaving skills to improve kesi silk tapestry. His younger sister, Lu Heng, awakens an extraordinary sensitivity to crop diseases because of her asthma. The family of four uses technology as a blade to carve a path through the chaos.
When corrupt officials oppress refugees with exorbitant taxes, Lu Yan puts his chemistry knowledge to work in a "divine punishment by copper sulfate" and even forges an "inspector's handwritten order" to outwit the county magistrate and seize land and resources. His mother, Madam Zhou, incorporates modern fashion into her loom and creates a kesi tapestry of the Mona Lisa that causes a sensation in Chang'an. She is named the "Silk-Weaving Immortal" in a court crafts competition. Lu Yan introduces the concept of hybrid rice, boosting yields from four shi per mu to twelve, astonishing the Minister of Revenue, who personally travels to Jiangnan. Even local strongman Li Sanduo and corrupt county magistrate Zhou Mingyuan are crushed by his technological edge and transformed from enemies into loyal followers, eager to serve him.
Set in the early Zhenguan era, the story cleverly blends historical research with the thrill of modern technology. From improving silkworm breeds to building irrigation works, from cotton trading to tax-system struggles, each technological breakthrough comes with a spectacular burst of knowledge. The modern catchphrase "That move was 666" even becomes Xuanzang's "supreme strategy" for translating scriptures. The family rises from refugees in a ruined temple to powerful officials and merchants: the father becomes a waterworks genius, the mother takes charge of the imperial workshops, and the sister becomes a gifted agricultural mind. Lu Yan uses agricultural technology to outpace the Tang dynasty by five hundred years, writing the legend of a modern transmigrator in the blank spaces of the history books.
