Use the Nascent Soul Realm to Fight Back to the Demonic Immortal Realm

My name is Chen Zifeng I was originally a casual cultivator in the world of demons and immortals. By chance, I obtained the entire inheritance of the Extinct Sect. Therefore, I took advantage of this opportunity to practice in the semi-immortal realm. Unfortunately, he was chased by three heavenly masters and was defeated. With crazy obsession and the remains of the 12 personal guards, and in order to prevent the sect's treasure from falling into the hands of others, he had no choice but to defy heaven and rely on the only wheel-wheeling bone in the world to open the crack in the passage between the world of demons and immortals and the human world, causing the wheel-wheeling bone to shatter into pieces. Later, he found a cave and hid there. He spent his whole life's spiritual energy hiding this place. Because of his obsession, he stayed here so that he could claim to be his soul body and wait for the person he was looking for. 100,000 Years later, a young man named Li Moyou was the one I was waiting for. Due to being bullied on campus, he fell into a cave and became a dying man. After making an oath to protect his sister to the death, he was willing to be taken away from him. From then on, I will survive as him and protect his sister. However, due to the weak spiritual energy in the human world and the strong power of the stars, I had to practice a single skill - "Xingyun Jue" that I got by chance. When I reach the Nascent Soul Realm and find a way to repair the wheel-turning bones, I will definitely fight my way back to the Demonic Immortal Realm...
