With the current territory of Su Country, as long as it is developed, it can accommodate four to five million people and support an army of two to three hundred thousand.
As long as Su Country can maintain its current territory and maintain stability within the country, it can accumulate the aforementioned population and army in sixty to seventy years.
By then, who can say that Su Country is not a great power?
As for Su Xuange's life span, living another sixty to seventy years is not an issue, and there is even a great chance of living another ten to twenty years.
The potential of the two prefectures and the sufficient lifespan of the Inborn Grandmasters are the decisive factors for outsiders to judge Su Country's power.
Other factors are just icing on the cake and secondary.
In this immortal world, even though it has reached the End of Dharma era, the gap between ordinary people and top martial artists and cultivators is still desperate.
