The small cauldron shook violently, trying to escape from Tang Hao's grasp, but endless poisonous mist rolled in from all directions.
Tang Hao's body flashed and he immediately returned to the divine boat. He opened the shield again to block the poisonous mist.
Then, he sat down cross-legged and activated the true fire in his body to refine the small cauldron.
"A mere seventh tribulation wants to refine this Lord!"
A Black Dragon rushed out of the cauldron and into Tang Hao's sea of consciousness, roaring.
This was the tool soul within the cauldron, the divine soul of a Black Dragon!
This small cauldron was a nine tribulations supreme weapon. As its weapon soul, this Black Dragon Soul was naturally not weak. As soon as it entered the sea of consciousness, it began to wreak havoc and stir up trouble everywhere.
"It's worthy of being a treasure of a poison immortal!"
Tang Hao said to himself.
