There's Something Wrong with This Cultivator

Reborn in a world of cultivating immortals, Li Bufan became a young monk of the Qingyun Sect. However, cultivating immortality seems a little different from what he imagined? The first time he meditated and fell into trance, he appeared in a bamboo forest. The figure of the immortal spirit was in front of him. Suddenly, a wolf demon rushed towards him from the side. Suddenly awakened from the severe pain, he found that he was still meditating on the spot, his clothes soaked in cold sweat. Is it inner demon? Is it an illusion? Or are you obsessed? He did not believe in evil and entered samadhi again. The same Qingzhu Mountain, the same wolf demon. This time, he lasted three more moves. From then on, he "cultivated" day after day. Get killed and get back up again and again. His classmates laughed at him for being able to meditate until he vomited blood. He was a crazy practitioner. But the master said that he entered the Tao through pain, and his Taoist heart was firm, and he would become a great person in the future. Until one day, the wolf demon in reality attacked, and he closed his eyes to avoid every attack. Li Bufan finally realized—— Is there something wrong with this practice?
