No matter if foreign enemies invade, they will be detected immediately and then be slain in an instant.
This also represents a tremendous enhancement in the security of border cities.
After all, with an Immortal King guarding the border city, what enemy could possibly breach this giant city?
It should be noted that among the Human clan, the number of Immortal Kings is extremely limited, only a little over a thousand.
Such scarce quantity of Immortal Kings makes it impossible to guard every city.
But now, with the appearance of the divine seal, even a Daluo Golden Immortal can possess Immortal King-level combat power.
Even if it holds only ordinary Immortal King power, it is quite exceptional.
This also means that in the future, Human Race Cities will be stable as a mountain.
There's fundamentally no fear of encountering foreign invasions.
