In a remote mountain village, there was a young man named Lin Feng. His parents died when he was young, and he lived with his elderly grandfather. Lin Feng is kind and brave by nature, and has a strong interest in martial arts. He often imitates the movements of martial arts masters in his spare time.
One day, Lin Feng went to the mountains to cut firewood as usual, but accidentally lost his way. While wandering around, he discovered a hidden cave. Out of curiosity, he bravely walked in. It was pitch dark inside the cave, and Lin Feng groped forward. Suddenly, a strange light illuminated the front. He walked quickly and found that the light came from an ancient book that exuded a mysterious atmosphere. As soon as Lin Feng touched it, the contents of the ancient book flooded into his mind. It turns out that this is a long-lost secret book of cultivating immortals called "Xuan Tian Jue".
