Liu Tian accidentally traveled to a magical alien world and discovered that elves used moonlight birthing techniques to grow glowing potatoes, and orc berserkers wielded axes to open up wasteland.
He silently took out "Essential Techniques for Elevating the People": "Why don't you try crop rotation?"
The elf elder laughed: "Mortals, without magic, no grass can grow!"
Liu Tian stubbornly reclaimed wasteland and built the first alien manure pile.
When his "organic magic field" produces sweet tomatoes, the elf's moonshine potatoes are instantly as sour as vinegar.
The orcs threw away their axes and lined up to buy iron plows, and the dwarf blacksmith studied the structure diagram of the biogas pit all night long.
The magic guild was furious: "He farms without magic. This is heresy!"
Liu Tian opened "Tiangong Kaiwu": "Science is the greatest magic."
