This is indeed a substantial benefit.
As for the eastern part of Qingzhou and some territories occupied by Xu State in the north, we can wait to deal with the opponent slowly after swallowing up the central region and crushing Liang.
Chu State still has many reserves of money and grain. This year, after a forceful operation cleaned up the western part of Qingzhou, many money and grains were also confiscated from the local noble families and sects.
Plus, with the stable environment in western Qingzhou after the cleanup, it is expected that next year, these areas can begin production, providing money and grain tributes to Chu State, which is another source of income.
Therefore, the reserves of money and grain in Chu State can be described as extremely rich.
Thus, even if we continue to maintain the current 18 million troops and the 18 million immigration projects, we can still hold on for another two years.
Having money and grain gives us confidence and morale.
