I Have a QQ Farm in Another World

He came to another world and became the lord of an island. He originally relied on knowledge to experience a stable life, but when he discovered that this was a strange world. Countless countries, including the Li family of the Tang Dynasty, the Zhu family of the Ming Dynasty, and even the great Qin Dynasty, dynasties have appeared in history, including the Roman Empire, various kingdoms in the west, and the thirty-six principalities of the Western Regions. There are countless continents that can be used for farming, minerals, and even fisheries. You have to kill strange beasts and produce a gemstone in your body, which can be put into the polluted land to farm. High-grade gemstones can open up secret realms of iron ore. But how can we defeat a hundred-meter stone man and a thousand-meter dragon? Can we use nuclear bombs to level them? Fortunately, he has QQ Farm, but it's just a bit of a money trap.
