Bringing The Farm To Another World

He can be arrogant, let him be; I'll just farm my own land. If you dare to provoke me, you won't last until next year. Zhao Hai, a homebody, transmigrated to another world with his QQ Farm, possessing the body of a fallen little noble. His fiefdom was a barren black land, and most importantly, he had an incredibly powerful fiancée, who was the heiress to a duchy, the future Grand Duchess! Most importantly, he was also a magical and martial arts waste, unable to learn magic or martial skills, completely useless. I can't learn magic, but I have a farm. You dare to attack me? I'll release insects to eat your army's food, eat your crops, poison your water sources with pesticides and herbicides, and plant weeds all over your land. Let's see if you still dare to attack me. What? You want to hire assassins to assassinate me? Hehehe, I'll hide in my farm's little house and see how you can get me. When you're gone, I'll make your country's food production fail, and then everyone will revolt against you. See if you still dare to kill me. Let's see how a somewhat cunning homebody uses his QQ Farm to become an existence that everyone in the world will have nightmares about in a world of swords and magic.
