The two demon spirits that had been on the edge of exploding finally underwent slight transformations as they slowly merged a little more.
Suppressed by Nie Li’s Heavenly Energy, the two demons spirits calmed their clash a little.
After roughly an hour, Nie Li felt like his supply of Heavenly Energy was nearly depleted. However, he could sense that the two demon spirits were almost done fusing, so he didn’t want to cut off the stream.
It was about to succeed! Nie Li didn’t want to give up here!
However, those two demon spirits were simply too powerful as they continued to mutually devour each other, producing berserk energy. If Nie Li were to do it alone with his own Heavenly Energy, it’d be impossible for him to suppress those demon spirits. If it weren’t for the vine inside of him that constantly provided him with Heavenly Energy, he would’ve been sucked dry long ago.
*Boom!* *Boom!*
Nie Li felt his own heart jumping as though it was echoing the sounds from the Nightmare Demon Pot.
Nie Li felt a little dizzy and his consciousness felt a little fuzzy. These were side effects from exhausting his Heavenly Energy.
It seemed that the task of forcing a fusion was still too difficult for him, especially with demon spirits of such high growth rates. After all, these processes usually had low success rates. Nie Li focused and squeezed out the last of his energy. If these two demon spirits actually exploded, then all his refining from earlier would go to waste!
