Martial Arts: the Coming of Ghosts and Gods

The protagonist traveled to the world of Yitian and Slaying Dragons and became Zhang Wuji. He was possessed by the system, and obtained the Nine Yin Manual from the Dragon Slaying Sword. He was about to return to the Central Plains to kill everyone, but he didn't expect to find out that there were ghosts in this world... "Why did Hero Guo become a ghost? Fortunately, he is a good ghost..." "Even Gang Leader Qiao actually swindled his body..." "Why did Huang Nuxia become like this... You are dead, are you Lin Chaoying?" "The Nine Yin Manual is nothing special, because I created it... I am Huang Shang..." "A certain family seeks defeat alone, but only seeks defeat..." Only then did Zhang Wuji discover that there were not only ghosts in this world, but also countless legendary martial arts people who transformed into ghosts and walked around in this world...
