Age of Empire: I Became Li Chengqian

Li Chengqian, who was checking information in the historical archives, traveled to the world of the Tang Dynasty. I thought that with his understanding of history and his status as a prince through time travel, he would definitely be able to accomplish something. But I didn't expect that this world was not just the Tang Dynasty, but a mixture of various historical countries at the same time. In the Western Qin Dynasty, the sixth generation of virtuous princes conquered the surrounding countries, spanning thousands of miles of territory, with hundreds of millions of subjects, and millions of armored men, dominating the west. The Han Dynasty in the central region built the country in troubled times and endured for three generations. Now the country is rich and the people are strong, and they are accumulating strength and are always ready to attack the Xiongnu in the north. The south was equally divided between the Song Dynasty and the Ming Dynasty. The Song Dynasty was rich and the Ming Dynasty had a strong army. Let's see how Li Chengqian turns his hand into clouds and rain, and strives for supremacy in the troubled times! The light of the sword stretches across three thousand miles, and the two hands push across a million divisions!
