Yun Woo is the youngest author in history to enter the literature world. His debut work was a massive hit but this success was short lived for the unprepared.

An intoxicated An Xiaoyu boldly places her hands on her hips: “Hey, handsome, this girl is here to rob you. This road is opened by me, this tree is planted by me, if you want to cross, leave some toll money!”The man approaches aggressively, trapping An Xiaoyu against the wall with no escape.He whispers in her ear: “Money, I have none. How about offering yourself instead?”An Xiaoyu is completely dumbfounded.She just accidentally robbed the wrong person, and now he's haunting her?What? He wants her to take responsibility?“Handsome, a forced melon is not sweet!”“No worries, I like bitter melons!”“You, shameless!”“Can't have a wife with too much pride!”“……”An Xiaoyu: “God, please let me go!”Ahem, 1v1 sweet romance + love over time, guaranteed to make you laugh until you have abs!

“If he’s being badass, I’m gonna plant my own crops. If he messes with me, he will not live past next year.”

Homebody Zhao Hai brought ‘QQ Farm’ along in his traversal to another world and resided within the body of a fallen noble. His fief was a black land which nothing could be planted, and more importantly, he even had a peerlessly powerful fiancee, who was actually the successor of a duchy and future Grand Duchess!

Even more importantly, he is a magical and martial cripple who could not learn magic and martial arts. His crippling was very thorough.

“I can’t learn magic, but I have the farm. You dare attack me? I’ll release bugs to eat up your rations and crops, and put pesticides and weed agents into your water sources to make your lands grow weeds. See if you dare to attack me. What? You wanna hire killers to assassinate me? Hehehe. I’ll hide inside the little house in my farm and see how you can attack me. When you leave, I’m gonna terminate your country’s crop productions, and then all of your people will revolt. See if you dare to kill me.”

Watch how this somewhat black hearted hobo uses his QQ Farm in the world of swords and magic to become a globally known nightmarish existence.
