Marry First and Fall in Love with a Cold Husband in Another World

[Two male protagonists + Shuang Jie 1v1 + Traveling through another world + Primitive society + Opening up wasteland and farming] Xize (cold but gentle) x Yu Li (beautiful, intelligent and affectionate) Traveling back to primitive society? Don't worry, as long as you have knowledge, you will never starve to death wherever you go. Nothing? A good life is created through labor. He knows a lot of things, but is he still worried about having a hard time? Did primitive society have no clothes to wear? It doesn't matter, he can make a loom. No furniture? Don't worry, he also knows a little bit about carpentry. Coarse salt is bitter and astringent? Purification is not a problem for him. Anyway, just do whatever you don't have! Whatever you want, do it! As for the cold Lao Gong... He thought it was just a fake show, but he didn't expect that the handsome guy was really doing it.
