Stay-At-Home Dad from Another World

Du Ze, who traveled to another world, expressed that he was very panicked. He suddenly became the father of three children, and his mother was the daughter of a grand duke! But I am a low-class person with no money and no status... Fortunately, raising a baby is ultimately a skill-testing job. When the baby is hungry, he has the skills to make delicious food; when the baby cries, he can tell a few fairy tales by Grimm and Andersen; as for my baby, he still wants to be the Lord of Beitong? This is easy to handle! Enclosing land to build cities, sowing and farming, commerce and trade, filling up technology trees... (Ps: Officially renamed "Full-time Dad from Another World".)
