Bringing a Farm to Another World

Zhao Hai, a shut-in, has traveled to another world with his QQ Farm, possessing the body of a struggling minor noble. His fief is a stretch of barren black soil where nothing can grow, and most importantly, he has an incredibly domineering fiancée—the heir to a principality and a future Grand Duchess! Most critically, he is a complete failure in both magic and martial arts; he can neither learn magic nor master combat skills, making him utterly useless. I can't learn magic, but I have my farm. You dare attack me? I'll release insects to devour your military rations and your crops, poison your water sources with pesticides and herbicides, and cover your lands in weeds. Let's see if you still dare to invade. What? You want to hire assassins to kill me? Hehehe, I'll just hide in my little farm cottage and watch you try. Once you leave, I'll ensure your country's food production fails completely, until everyone rises up in rebellion against you. Then, let's see if you still dare to come after me. Watch as a slightly devious shut-in uses his QQ Farm to become a nightmare-inducing existence to everyone in a world of swords and magic.
