I! Ghost Immortal, Sign in for a Thousand Years and Become an Immortal Emperor

Lin Yu was reborn in a strange fantasy world where ghosts and immortal cultivators coexist. At the beginning, a god-level sign-in system was bound to the system, and he quickly became a ghost fairy. Sign in to the human world, sign in and be rewarded with the Flying Sky Escape Technique. Sign in in the mountains, and sign in will reward you with a curse. Sign in at Gufen, and you will be rewarded with Ghost Flute and World-Destroying Black Lotus. Sign in in the restricted area, and sign in to reward five innate spiritual treasures of the Ghost Emperor's magic. Who says ghosts and fairies are not fairies? With one command, all the powerful ghosts in the sky can be controlled. Whether it is the Holy Lord or the Xuanmen Sect Master, they will all surrender under his feet... Um, okay, I forgot to mention that a thousand years later, Lin Yu became an Immortal Emperor, married the Empress of the Nine Heavens as his wife, unified the universe, and used the ghost way to suppress the heavenly way. He was the only one who was supreme. This book is my ghost and immortal again, shocking the whole world of immortality. This novel and its characters are purely fictitious.
