Demon King, Guarding the Two Realms of Yin and Yang

When the underworld was first built, there was chaos. There are great masters from the world who break into the underworld at will and modify the book of life and death, while there are also real monks who forcefully break into the river of Hades and take away the souls of their relatives and friends. There are ghost kings from the underworld who secretly stir up trouble and trigger wars in the ghost world. There are also Shura ghosts who don't follow the laws and stay in the world to cause trouble. However, all this changed when Fang Yu traveled to the underworld with her computer and became an eight-year-old naughty child. The computer screen plays the exercises and you can learn them in one go. The hard disk data is synthesized into Wuji Kung Fu, making you invincible with one punch. The keyboard is even more powerful, capable of outputting great horror. From then on, ghosts and ghosts ran for their lives, the war between immortals and demons ended, the worlds of Yin and Yang were balanced, and order was restored. In a dark corner, the demons and ghosts that escaped the net were huddled together and trembling. The big devil is here again! This novel and its characters are purely fictitious.
