Chapter 900 - Mystic Light Realm Sacred Lord
Zhao Feng had nine portions of the Hundred Origin Sacred Honey remaining after giving one to Supreme Emperor Dark Night.
He needed three portions for himself. The first would be used when he was about to reach the limit of the Sacred Lightning Body's 5th level, the second would be used when he was about to break through to the Mystic Light Realm, and the third would be used to break through to the 6th level of the Sacred Lightning Body.
In reality, using the Hundred Origin Sacred Honey more than once would decrease its effects, so using more than three portions or even just two would waste some of the Hundred Origin Sacred Honey's value.
