Maritime Merchants of the Ming Dynasty, from Three Pennies to Maritime Overlord

In the sixth year of Xuande, Lu Ming only had a chart of Zheng He's voyages to the West and three copper coins. The imperial court wanted to close the sea and the treasure ships were in port, but there was still a way out on the sea. Carrying a nautical chart, he boarded a private merchant ship and started working as a cargo man. In a naval battle, he spotted the tide and dark sand, killed three brothers and sank five Japanese ships. From that day on, no one on the Qiongzhou sea dared to look down upon these three words, Kui Mark. But he wants more than that - he wants to have access to this sea; he wants to be rich in this world. The first step is to start with an old boat.
