Liang Yu traveled to an alien island and became the most miserable refugee. He started with a broken boat and made a living by fishing. Until he met the old fox Ye Hui and tricked him into buying Shuguang Island, a broken island known as "noble status". Everyone laughs at him for being taken advantage of. This island is barren and desolate, and there are extreme cold storms and pirate raids every year. Whoever buys it is stupid!
Liang Yu smiled. He can travel back and forth to the real world in seven days! Selling supplies is just the basics, building houses with cement, modern medical skills, and gunpowder weapons are the best! When others were still using wooden spears, his army was equipped with fine steel crossbows; when other islands were worried about food, he distributed it for free just to win people's hearts; when the nobles indulged in pleasure, he silently lit up the science and technology tree, built infrastructure, built education, and built hospitals!
