[Western Fantasy + Farming + Industry + Witch + Light System]
Agricultural researcher Lin En traveled through time and became the son of a businessman who was falsely accused. Faced with drought and the lord's gallows, he did not beg for mercy, but pointed to the cracked surface: "Your Majesty, I know where the water is!"
With his systematic [God-level geological exploration], he not only dug out underground rivers, but also planted potatoes with a yield of 10,000 kilograms per acre.
Just when the nobles laughed at him for taking in a useless witch who "only decomposes garbage", Linn had already started the industrial revolution.
When decomposition capabilities turn into precision machine tools, and when fireworks turn into explosives, Lynn's industrial giant ship has risen on the border of the Duchy.
