Next, they needed to find a navy general.
The top ten navy generals in China included the Three Kingdoms Era Zhou Yu, Tang Dynasty Liu Rengui, South Song Era Li Bao and Zhang Hongfan, Yuan Dynasty Yu Tonghai, Ming Dynasty Zheng He, Deng Zilong, Yu Dayou, and Zheng Chenggong, and the last was Shi Lang from the Qing Dynasty. Near the end of the Qing Dynasty, when Deng Shichang was a general, they already had iron warships.
Out of all these generals, the earliest Zhou Yu appeared during the Three Kingdoms Era.
