บท 821: The Surrender of Ghost King

Zhang Ruochen tried to crack the Sun-moon Crystal Coffin again. He even borrowed the Void Sword from Han Xue this time. But still, he couldn't open it.

At last, he had to give up and stop trying.

"It is written in ancient books that the Sun-moon Crystal Coffin was a saint weapon of the Moon Worship Demonic Sect, which had been passing it on for a long time and learning of its many uses. After this woman died, she used Sun-moon Crystal Coffin to contain her body, which means that this woman was at least a Palace Ruler or a Saintess, or even an old Hierarch," Zhang Ruochen said.

Neither Zhang Ruochen nor Blackie knew much about Sun-moon Crystal Coffin. They had to return to Kunlun's Field and go through all the files of the Moon Worship Demonic Sect to find this woman's identity.

Such a figure like her must be well-known. Therefore, it shouldn't be of much trouble to find her identity.
