Lin Chen, a top aerospace engineer and history enthusiast, accidentally traveled through a supernatural star, and his soul possessed a down-and-out scholar from the Dayin Dynasty, a dynasty similar to ancient China but in an era of civilization and technology loss. At this time, the dynasty was suffering from internal and external troubles, natural disasters continued, and foreign races were watching with eager eyes. Relying on the scientific knowledge and historical insights that transcended the times, as well as the remains of a severely damaged personal terminal that he carried with him that contained a large amount of modern data, Lin Chen started to make soap and improve agricultural tools, and gradually rose to prominence. He met like-minded partners, encountered stubborn and conservative enemies, and became involved in the deep power struggle of the dynasty and an ancient secret about "the fall of stars and the reincarnation of civilization." What he has to do is not only to survive and get rich, but also to use the spark of modern technology to rekindle the fire of civilization in this lost era, resist the coming catastrophe, and on this road, find his own home and return.
