Wei Cheng seemed to have forgotten the purpose of his journey to the south.
The life and death of the Supreme Sovereign of demons no longer mattered to him.
Ever since the last fine-tuning of the ecology in the Immortal World, he had been squatting in that Forbidden Pit, accompanied by the ancient forbidden being, lost day and night in its mysteries.
He even allowed the ancient forbidden being to devour him, to envelop and consume him...
He wasn't researching this ancient forbidden being, nor was he observing it. He wasn't even hiding from anything; he was just waiting.
Ever since he concluded that the source of changes in the Immortal World's ecology might be related to the decomposition and evolution of forbidden beings after their death, he had developed a keen interest in it.
