I Am Cultivating Immortality Through Righteous Methods, but the World Calls Me a Devil

This time the world is full of spiritual power, and it is possible to attain immortality. But Zhang Fengyi was annoyed. He was originally the 67th generation Heavenly Master of Longhu Mountain, mastering the Five Thunder Dharma. When I came to this world, I originally wanted to eliminate demons, protect the Tao, and help the world, but I didn't want to time travel into an evil cultivator. It doesn't matter, it's possible to correct the evil and return to the right path. However, when he studied "Palm Thunder", it evolved into "Bone Erosion Thunder". When learning the "Heart Purifying Mantra", it evolved into the "Magic Sound Seizing Soul". When casting the "Golden Light Divine Spell", he was surrounded by hundreds of ghosts, and countless demons and strange images appeared behind him. Zhang Fengyi was confused, this was making him a destined devil! ..... Thousands of years later, Zhang Fengyi was dressed in black robes, with his back turned to all sentient beings. "In a world of chaos and chaos caused by evil and evil, and the collapse of reincarnation, where will the Buddha be?" "The world is suffering and natural disasters occur frequently. Where can the immortals be?" "The distinction between good and evil in this world should not be divided by martial arts, but by human hearts!" "Immortals and Buddhas will not cross over to the human world, I will!"
