After understanding the grudge between Yin Rong and the Dark Night Ghost Sect, Donor also said, "To be honest, the Dark Night Ghost Sect has always been a huge tumor in the Light Sea. To be honest, its existence is also a provocation to the Elven royal family."
The Dark Night Ghost Sect had existed for more than two thousand years. Sheng Xiao and the others didn't know where this organization came from. Besides, the Light Sea and the Divine Realm Continent were not in close contact more than two thousand years ago. At that time, nothing major happened. The continents never formed alliances easily.
It was only when planes appeared more than a hundred years ago that the communication between the various continents became closer. Later, the birth of the internet tightened the friendship between the various continents.
Therefore, no one knew the exact background of the Dark Night Ghost Sect.
