In the third year of Yongle, the Lin family business in Quanzhou Port. When the concubine Lin Yanzhou was working in the spice warehouse, an ancient technological tree suddenly exploded in his mind - steam engines, iron smelting, mechanical mechanics... And even complete mecha blueprints. But before he could get excited, two death lines popped up in the system: First, he had ancient cursed blood flowing in his body and could not store spiritual energy. He would die at the age of twenty. Second, each mecha consumes Xuan Jing, and the mining of Xuan Jing will trigger earthquakes in the earth's veins and cause natural disasters. What's worse is that the imperial court's "Tianjia" troops are patrolling the sea. The copper and iron mechanisms on Zheng He's treasure ship are just the tip of the iceberg of the divine machine civilization; and in the dark, there are unknown time travellers, stirring up the storm with fragments of knowledge. Lin Yanzhou gritted his teeth and took over a dilapidated merchant ship, starting from bidding for colored cotton to defeat Zhao Yuanlang's usury campaign; he found the first Xuanjing mine on a deserted island in the South China Sea, which skyrocketed the system's wealth; he used scrapped parts to build a rudimentary mecha, defeating the pirates' high-level mecha beasts with David and Goliath. But the severe pain of the curse became more and more frequent. His ally Zhongbo was penetrated by mecha fragments while trying to save him, but Zheng He himself suddenly asked him: "Are you from that era too?" He only had seven years left. Mechas need to be built, mineral veins need to be robbed, time travelers need to fight, and the catastrophe of heaven and earth needs to be blocked - Lin Yanzhou clenched the wrench and pointed it at the sky: "Then first dismantle this bullshit destiny."
