What is Jiu Feng Supreme?

Nine supreme letters are the stalks of "I want to seal the sky" Nine supreme letters mean supreme, the strongest in heaven, surpassing half a step. The characters in the online classic Xianxia novel I want to seal the sky, which was created by China's online classic Xianxia novelist, were once enemies of the celestial world and the underworld. Later, every time I talked about "I want to seal the sky", fans would think of the stalk of "Nine Supreme".
