Su Zimo did not know much about the four immortal sects and merely heard about them for the first time in the battle of the Dragon Abyss Star.
In the Heavenly World, sects were divided into three grades—black, earth and heaven.
Under normal circumstances, those who ascended from the lower worlds did not even have the chance to enter black-grade sects.
As for the four immortal sects, they were heaven-grade sects of Divine Firmament Mainland and one could imagine their strength.
Among the three men, one of them was bald with a fat head and ears like a monk.
Another had dark skin, a tall figure and short hair, resembling a walking iron tower.
The third was a middle-aged man with a Dao crown on his head. His sleeves fluttered and he was dark and calm.
The woman wore a blue dress and her lips were scarlet with a hint of purple—she looked a little terrifying.
