Ye Zhen met Pill King Shuilian within the Mirage Dragon Pearl Temporal Space.
Pill King Peng had followed Ye Zhen to the Primordial Continent for so many years. Originally, according to Ye Zhen's wishes, a Medicine King Manor was to be built for him deep within the mountains of North Sea Commandery, his current fief, so that he could research pills and train disciples.
Pill King Shuilian had agreed to it at the time.
However, ever since learning that Ye Zhen's Mirage Dragon Pearl Space contained a tenfold Temporal Space, and later a hundredfold Temporal Space, Pill King Shuilian had become completely obsessed.
He stayed within the hundredfold Temporal Space, researching the Dao of pills day and night, unwilling to come out.
In his words, what did the path of pill research lack most?
It was not Heavenly Materials and Earthly Treasures, but time!
Only with a vast ocean of time could one reach an unprecedented height on the path of pills, even breaking through the boundaries of their predecessors' research.
Basically, Pill King Shuilian and his disciples had spent all these years within the hundredfold Temporal Space of the Mirage Dragon Pearl.
Of course, Ye Zhen had not left them entirely to themselves. He had done a few things for them.
For instance, he had built several alchemist residences for them inside the Mirage Dragon Pearl, at the very least giving them a good living environment.
Mirage Dragon Primordial Spirit Ah Chou had also long maintained an illusion—a nearly entirely real, breathtaking world of changing seasons within their living grounds.
Naturally, chefs and maidservants to attend to their daily needs were indispensable as well. Those Devil Race captives were the best candidates.
Counting carefully, Pill King Shuilian had spent more than a thousand years within the Mirage Dragon Pearl
