Later, expert Wang Baobao has been dealing with the Ming Dynasty, but he was defeated more than he was defeated. At that time, the stars were like clouds, and Kitahara had been defeated and fled, but the main force was still there. Later, Hailan broke Beiyuan in Yueerhai, and almost destroyed the main force of Beiyuan. However, ethnic minorities in the north are all like this. As long as there is a little sunshine, they will be brilliant. Tatars, Walla people and Wuliangha people have gradually appeared on the grasslands in the north.
