1971 Tribulation

Within the immortal grade, nine times reinforced pills were the pinnacle standard as well. However, the difference was that in order to be reinforced, unlike mortal grade pills, immortal grade pills needed to withstand a tribulation! 

A single lightning strike… That meant Dyon had refined a one time reinforced immortal grade pill! 

How could Supreme Spiritual not faint? Refining a pill of the immortal grade standard was hard enough. But to reach past the top-grade? On what should have been his first attempt as well? How could he not feel like dying? 

Dyon wasn't very worried about this tribulation lightning. Only the tribulation lightning of the Immortal Plane could threaten his pill. He was technically cheating by creating an Immortal Grade Pill on the mortal plane.
