Lü Jiangcheng (1)
In the afternoon, Zhao Hai and the others finally saw lü River City. Lü River City was not only close to the lü River. In fact, they had excavated a moat and a city-crossing river to guide the water of lü River to the outside of lü River City. It became the moat, and another branch was led into lü River to become the city-crossing river. Therefore, apart from the ordinary city gate, lü River City had two Watergate. These two Watergate gates allowed some small and medium-sized warships to pass through.
Lü Jiang city was huge. It was a large city with a population of over a million. In this era where there were not many high-rise buildings, one could imagine how big this city was.
