The Winged Man Valley was considered a vassal of Nether Prison. Its geographical location was not far from the latter.
Nether Prison once invaded it, but its Great Saints stopped the invasion. In the end, the top leaders of the two small worlds sat down to make peace and signed some treaties. After that, the Winged Man Valley had a rapid development over the years, and one of the reasons was Nether Prison's timely assistance.
The cultivation base of winged men was ranked according to the number of their wings—the more wings, the stronger the strength. The figure in midair had two pairs of wings, and a terrifying fluctuation emanated from him, accompanied by holy light that lit up the whole world. That was the shocking power of a Great Saint.
