Any magician who has had the world secret domain for more than ten years will find a mechanism: the strength of the world secret domain is proportional to the size.
With the expansion of the secret realm, power and ability will also be strengthened; As the secret domain shrinks, so does the power.
But if the secret domain of the smallest unit is set to have 100 powers, then the secret domain of 100 units only has 101 powers. That is to say, although the size of the secret domain can affect the power level, the influence factor is very low, even the long-lived god will not use this mechanism. After all, it is more appropriate to use the secret domain to produce various resources than to expand the secret domain with a little power growth
