The only way of life left for Chu and Ning Countries was to make a northern breakthrough, to take over the land of Central State where Liang resided, seeking survival in this move.
By then, perhaps Chu and Ning could turn their weapons into gifts of silk, joining hands to embark on a Northern Expedition together.
In doing so, they would truly have overcome this great calamity between Heaven and Earth, preserving the ancestral temples of the six clans and seven families.
All of these strategies were based on Bai Yian's true method to break the current stalemate, the only way out for the six clans and seven families, considering various actions up to now.
That's why after his earlier strategy for a decisive battle was rejected, he proposed an equally extreme conservative strategy.
The goal was to preserve the Jiangdong foundation to endure until the great calamity a hundred years later, the last chance for survival.
