Traveling Back to Ancient Times, Two Men and Four Women Took over the World

Two 985 graduate student male protagonists, one from the physics department and the other from the economics department, traveled to the ancient Zhou Dynasty. One person and two wives, a novel about farming, business wars, intrigues, battles of wits, harems, and suspense. It is pure information without cheating. First novel, sorry. Tomato won't let me finish. How to fix it. By chapter 28, it's already a perfect ending. If anyone is still watching. I will continue writing the second part.
