Clearly, Zhou Sui's powerful Primordial Spirit immediately attracted countless Heavenly Demons from the depths of void.
Especially those Demon Emperors standing at the pinnacle of Heavenly Demons.
It was as if a sun was shining, illuminating the void, penetrating countless levels of Dimensional Space-Time, and reaching the space of Heavenly Demons.
It also informed many Demon Emperors at the very first moment.
For them, the sudden appearance of such a Primordial Spirit was no less than a hundred-thousand-year-old Eighth Grade Spiritual Medicine maturing, naturally drawing in swarms of Heavenly Demons.
Many Demon Emperors would also kill their way over, vying for this opportunity.
This is why the deeper the foundation of a Union Cultivator, the more terrifying the Heart Devil Tribulation they face.
Now it was the same for Zhou Sui.
Boom~~~
