With the never-ending changes of the heavens, earth and oceans, there may be spell formations born from these natural phenomena, capturing the spiritual energy of nature, complex and mystifying.
These ancient formations are vastly different from the current ones employed by human and demon cultivators passed down from older generations. Most sects and tribes actually derive their inspirations for their spell formations from these ancient formations, which gradually evolved to their current forms. And due to the frequent conflicts and clashes between the human cultivators and demon tribes, the ancient formations born from natural phenomena have become exceedingly rare, like this complete and enormous ancient formation atop the Yingzhou Celestial Mountains.
