Cyrus, a poor micro-carver, accidentally binds to a micro sandbox and becomes The Creator of the Great Yan in a tiny kingdom. When Jocelyn, the female emperor of Great Yan, faces natural disasters and ferocious beasts, he performs miracles using ordinary items such as water, warm light, and insecticides, and receives priceless micro-carving treasures including Xumi rice and the Nine-Dragon Vessel in return. He sells these treasures to pay off his debts, buys a luxury mansion, and founds a precision medical technology company. He continuously sends supplies such as seeds and batteries to Great Yan, guides its development of smelting and electrical technology, and the tiny kingdom feeds back nanometer-level precision devices in return. Eventually, he breaks the overseas medical technology monopoly, taking care of both his micro subjects and the real-world public.
