The fierce clashes in the sky lasted for an hour. The armies from various factions retreated to their respective backlines to avoid being consumed in clashes between pinnacle-level powerhouses.
The battlefield around the ancient secret realm's portal had become a wasteland with lots of demonic energy, poison, and darkness.
Thousands of moves collided between eight ancient demon ancestors against the God of Poison from the upper realm. The naked eye couldn't follow the exchanges in each clash.
The Great Sage Black Dragon, also known as The God of Poison, activated his domain. A massive spherical domain then trapped the eight ancient demon ancestors. Their fight continued in the poison domain.
The ancient demon kings and their elite warriors massacred the Tiangong Sacred Land's people, including the reinforcements that arrived too late.
The massive flying serpent retreated into the poison domain. The ancient demons accomplished their tasks with minimal casualties.
Without justice, there is no peace. No everlasting peace, anyway.
