Various mystical Dao rhythms appeared within the formation, as four virtual saints sat cross-legged inside.
Peter Brown had never expected that the formation he created could be upgraded to such a level. Without even thinking, he knew he had crafted an extraordinary formation.
All around him, Peter felt the dense demonic energy fading away. As the Demon Saint perished, the whole Demon Clan's land now clearly emanated bursts of holy fate Qi dispersing into the azure sky.
Peter had never seen such a phenomenon before. Only now did he understand the true origin of holy fate—it was generated from the essence of a fallen Saint.
What a pity!
Peter tried to grasp it, only to discover that his current cultivation was far too weak to hold onto it.
After all, his cultivation still wasn't sufficient!
Nevertheless, Peter didn't dwell on this. With a formation now capable of truly killing Saints, he no longer feared their arrival.
