After returning to his cave abode, Chen Lin began thinking about the Hanhai Immortal Palace that the Baozhen Pavilion shopkeeper had mentioned.
He had heard the name before. It was actually the imperial palace of the Hanhai Ancient Country. After the country fell, the palace had somehow survived and become something akin to a secret realm.
It appeared roughly once every five hundred years, at the original site of the Hanhai Ancient Country's imperial palace, a thousand li outside Wanmeng Immortal City.
More than five hundred years had passed since the secret realm last appeared, so there was nothing strange about it opening now.
According to the records he had read, this secret realm was quite famous and contained many treasures, but also many dangers. Originally, he had no interest in it.
However, one piece of information the Baozhen Pavilion shopkeeper mentioned had made Chen Lin hesitate.
During the ancient cultivation era, the Hanhai Ancient Country's royal family had been immensely powerful, with cultivators at spirit transformation or even higher levels. They also possessed an extremely famous spirit treasure called the Liangyi Disk.
This spirit treasure was said to have been destroyed in the great war, but it had formed a peculiar region within the secret realm. Every time the secret realm reopened, heaven and earth treasures of utmost yin and utmost yang would appear there.
He had now gathered all the five elements materials needed to refine the Six-Pattern Seven-Star Pill. All he lacked were yin- and yang-attribute materials of the same grade, so this information was deeply tempting.
Cultivators were generally unwilling to sell materials of such a grade. Anyone who obtained them would keep them for their own use at a critical moment. In the past, he could have searched at his leisure, but circumstances had changed.
