The spies that are flying as fast as they can toward that area suddenly halted in their rush.
They were shocked because this aura coming out form this roar is the aura of a Diamond Dispersal expert.
How could suddenly such an expert appears in this remote region? And they were also shocked because the closer they come; the aura instead of being weakened is getting stronger.
And then they felt it. Deep in their heart. A desire to bow. This is an innate desire, an innate instinct.
Even Celestial with all of their powers could not have such a profound pressure to force their race to bow and kneel.
This is only if they met a powerful person of their own race.
While the Infernal Realm has the nine level and four stages, their races bloodline also have levels.
This is their race bloodline of Kings.
It would only appear on someone who cultivated the pure infernal energy.
