Speaking of which, the current Heaven Realm's Shadow Sect in the Northern Region is like a mouse on the street, too afraid to show itself.
Wu Zuo was very powerful and ruthless. The Divine Temple is responsible for managing the Four Great Secret Realms, and with so many people in the Elder Palace, they only oversee the Northern Region. Soon, they transformed the entire Northern Region into a unified entity. All sects must make offerings every year; whoever stops will face death.
Every cultivator reaching the level of Grand Yan Immortal must register at the Elder Palace's gate. Those without clear identities are to be executed.
Moreover, an outer palace has been established, and even Emperors are forcibly enrolled. Refusing to be listed in the outer palace means death.
Wu Zuo personally hunts down those Emperors who try to escape.
