The innate energy in the Innate Dao Fruit was far beyond his limit, it was still expanding his mortal body bigger every second. Fortunately, the Lei Zhe Continent was huge enough to contain him, else he would have his head out in the outer space. But even so, his head had also extended into the lightning zone.
The innate energy was overbearingly strong and pure, and most importantly, it was in huge abundance. Even with Zhong Yue mustering up everything he had in his Yuan Shen, mortal body, arcane energy, psyche, and blood essence to refine the innate energy into his mortal body, the abundant innate energy was still too much to control.
Finally, when he felt his mortal body start to crumble into bits, the overwhelming pressure forced Zhong Yue to open up his mouth and spurt out the excessive innate energy.
Soon after, he spurted out another mouthful of innate energy again.
