Rumble—
Inside the refinement room, a swirling black cloud appeared above the Creation Cauldron. Countless hair-thin electric arcs danced within the cloud, occasionally releasing deafening thunderclaps.
This abnormal phenomenon had lasted for three continuous two-hour intervals, and not only showed no signs of subsiding, but had grown increasingly intense.
Sitting in front of the cauldron, Wang Chen seemed completely unaware of the commotion, focusing all his mind and strength on the interior of the treasured cauldron before him.
The upgrade of the Dragon Abyss Sword had reached its final stage, where even the slightest mistake could lead to complete failure.
The loss would be immeasurable!
Crack!
A bolt of lightning suddenly struck the lid of the Creation Cauldron.
The cauldron didn't budge, but Wang Chen visibly trembled as though he had been struck himself, his aura momentarily thrown into disarray.
