After eating his fill, Tiger Might began to explain to Su Ying what had happened during this period of time.
"That fellow Cheng Ming was the one who discovered the mine first."
After Su Ying and Xiao Jin returned to the Chu State, Chu Yun and the rest had always adhered to Su Ying's governance philosophy. They felt that if they wanted the people of the northern wilderness to live a stable life, the first priority was to ensure everyone could fill their stomachs.
Only when one's stomach was filled could he engage in thinking and other tasks.
So even after Su Ying left, Chu Yun would still get Cheng Ming to bring people to continue developing wasteland and increase the amount of arable land. This would then ensure there were sufficient food crops.
