Flee when you're done
Initially, the soldiers of the 6th Combat Brigade were actually quite nervous when they heard they would be heading to the Central Plains. After all, the wars they had been fighting were all in the Northwest. They were used to the conditions there, so even if they could not defeat the enemy, they still had comrades they could depend on.
But now, they were more than a 1,000 kilometers away from Fortress 178 at Mt. Zuoyun. By the time their reinforcements arrived, they themselves would probably be dead.
Later, everyone heard that some Central Plains people who were part of the Prosperous Northwest would join them, but they did not pay much attention to it. In truth, Wang Yun and the others were not enough to reassure the 6th Combat Brigade.
