Fortunately, Lu Yuan had never expected both nations to help in this regard.
What he truly valued were the two Inborn Grandmasters, Yan Wangqiu and Su Xuange.
If these two were there, coupled with himself and Lan Cai'er, their united army would form an absolute advantage in ultimate combat strength against Zhou people, outnumbering them with four Inborn Grandmasters.
Four Inborn Grandmasters, that is certainly not a small force.
Based on the idea that a single Inborn Grandmaster can easily defeat ten thousand soldiers, four Inborn Grandmasters gathered together could match forty thousand elite troops in a narrow battlefield.
These are just basic numerical conversions.
Reality is, on the actual battlefield, in a restricted range, the effectiveness of these four grandmasters would be far superior to that of forty thousand soldiers.
Take the simplest example.
