Cao Zhao passed through the book, and landed in a desperate situation: a destitute scholar, heavily in debt, and being pinned to the ground to destroy his body and eliminate traces. Fortunately, he came with the modern knowledge of another world, and had a complete set of "Principles of Everything" bound in his mind. From farming to industry, he was proficient in everything. Starting from a dry well at the head of the village, he repaired a waterwheel, cultivated improved seeds, engaged in printing, and opened a workshop, and he turned a poor mountain village into a well-known and wealthy land. Just when life was about to get comfortable, an alien who called himself the "Civilized Prosecutor" fell from the sky. According to the setting, he should have wiped out the earth easily, but he felt that the work was too tiring, so he just put it aside and stayed in Cao Zhao's yard eating melons and basking in the sun. Cao Zhao soon discovered that the countdown on the alien's wrist was still rapidly returning to zero - if he continued to lie flat like this, the earth would be buried with him. As a result, a modern man who doesn't want to work overtime and an alien who doesn't want to go to work are forced to start an absurd and heart-warming "ball keeping" cooperation. From the countryside to the county town, from the court to the sea of stars, Cao Zhao used knowledge to drag the aliens to change the world step by step, and finally revealed that there was a universe-level secret hidden behind this guy's mess.
