Moreover, the entire Holy City is filled with mixed forces; if a force does not have at least a half-step Life and Death Realm King overseeing it, it simply cannot survive in the Holy City.
In the Holy City, there are two most conspicuous buildings: one is the Palace of Life and Death at the peak of the Holy City, which controls the entire Celestial Martial Continent, and the other is the Holy Monument in the center of the city.
As for the Palace of Life and Death, there's no need to elaborate, but the Holy Monument is quite interesting.
The Holy Monument has existed since the rise of the Human Race, with a history of millions of years. It contains dense Secrets of Space and Secrets of Life and Death. Every seven days, the Holy Monument opens once, allowing any Transcendent Expert to enter.
