Sure enough, after driving out a surge of black fire again, Liu Chen felt that the entire furnace was already burning up, which gave him quite a shock. It really was incredible. If there were no herbs inside, even a hundred alchemy furnaces would have been reduced to ashes by now.
But because the temperature inside this alchemy furnace never reached its peak, no matter how fiercely it burned outside, it wouldn't destroy the whole furnace.
He didn't know how long it had been, but Liu Chen felt soaked to the skin. The spiritual energy output was too great, making it feel like the cave had become a Flame Mountain. Finally, he seemed to hear a bubbling sound.
"Oh my god, is it just boiling now?"
Liu Chen's mind was full of turmoil, thinking the boiling point must have reached a hundred thousand degrees, considering how long it took to boil. However, at this time, he dared not lift the lid. If the temperature were released, it would probably have to gather again.
