Man tribe owned Hong Yan valley, they had won a few battles these years and had expanded greatly.
Northern plains was different from southern border.
Southern borders had a forest and mountain terrain, it was easy to defend but hard to attack, long distance travelling causes huge expenditure. Southern border clans worked on self development, accumulating slowly and growing stably, keeping a pure bloodline.
But northern plains was a huge grassland, there were lots of conquests going on. The tribes of northern plains rise up fast but also fall just as quickly. A few wins might allow a small size tribe to become a medium size tribe, and from a medium size tribe, expand into a large size tribe. But one loss could also cause this large size tribe to break down into numerous small size tribes.
Man tribe had absorbed Shi tribe recently, and the elder Shi Wu from Shi tribe became Man tribe's external elder.
