Chapter 3208: Grade-Three Secret Realm

The glowing black pill that Jun Chong Shan had consumed was called the Reversal Poison Pill. Most people used the pill to harm others. It could even cause a Celestial Lord's cultivation base to regress if the antidote was not taken.

In Jun Chong Shan's case, however, he had taken the pill so that his cultivation would regress back to that of a Ten Directions Celestial King, which would then allow him to enter the upper realm of the Southern Heaven Ancient Realm.

Due to Jun Chong Shan's precise and tight control over the pill's effect, he was able to retain part of the strength of his Celestial Origin Energy that was akin to that of a One Basic Celestial Lord despite having reverted to a Ten Directions Celestial King.

To raise his cultivation base back to that of a One Basic Celestial Lord, he would first need to cleanse the poison left behind by the Reversal Poison Pill in his body. It would take him at least thirty to fifty years to do so.
