Release the Celestial Captives, Open the Hunting Ground

When Zhang Ruochen was in seclusion in Sevenstar Imperial Palace, he spent a lot of time studying the fifth level technique of Incarceration of Divine Demon. He even took out Demonic Incarceration Portrait to comprehend it.

However, it was a high-level Thousand-Koan Saint Technique that even a Thousand-Koan Realm Supreme Saint would need a long time to master.

Probably due to the great difference in cultivation levels, even with the help of the Heart of Truth, Zhang Ruochen still felt that the fifth level technique was abstruse. There were still many aspects that he failed to understand.

Zhang Ruochen had asked Divine Sky-connecting Tree for advice. Divine Sky-connecting Tree had told him that when a cultivator executed a high-level Saint Technique, not only the person's power was activated. The technique would also activate or affect the surrounding energy.

It was like when a mortal was waving his palm, it would bring a slight wind.
