The greatest secret within Sky Demon Secret Cave was that it imprisoned a Fire Qilin!
The Fire Qilin was the fiercest intelligent creature with the greatest yang qi. It was different from ordinary intelligent beasts and was very smart. It could live for a long time, and its strength was comparable to that of a powerful martial artist in Myth Realm!
Sky Demon Sect might have one Fire Qilin, but they could not control it. In the end, they could only set up a matrix and set up an environment that was of extreme yang and extreme yin in the cave where the qilin stayed.
The extreme yang environment was a place where the Fire Qilin loved staying, and the extreme yin environment was where Sky Demon Sect rested and grew. It was also where Sky Demon Secret Cave was, which was also the place where the real Sky Demon Sect was located!
