A Ghost's Self-Cultivation

After an accidental fart, Yuan Zhi became a wandering soul with an absurdly slow speed. He thought he would slowly become moldy in Jiuyou, but unexpectedly he awakened the Jiuyou system and accidentally inherited the inheritance of the underworld! While others rely on hard work to cultivate, he relies on systematic tasks and obtaining authority from the Book of Life and Death. He accepted Wu Chang as his younger brother, controlled the ten palaces of Yama, and took charge of the order of the underworld. A ghost suddenly became the leader of the underworld! I thought that the carefree underworld was enough, but a sudden disaster swept across China, demons were rampant, and the three realms were in turmoil! Sun Wukong, Erlang Shen and other mythical powerhouses came through the void one after another. Since the underworld is not enough, let's just sweep across the three realms! From a humble and lonely soul to taking charge of the three realms of Yin and Yang and Dingding! This ghost is about to cause a shocking catastrophe!
