Ling Yun and Su Muyao went deep into the extremely dangerous Cangwu Fairy Mountain in order to find the thousand-year-old spiritual herb that could heal the sect's elders. This mountain is rich in aura but contains hidden murderous intent. Monsters are entrenched, miasma is permeating the mountain, and ancient restrictions are spread throughout it.
Relying on Ling Yun's exquisite swordsmanship and Su Muyao's psychic skills, the two overcame obstacles along the way, evading the poisonous fog and repelling the bloodthirsty demon wolf. Just when they found the spiritual grass, they accidentally touched the ancient seal and awakened the demonized mountain god who had been sleeping for thousands of years.
The power of the mountain god is unfathomable, and the two of them are instantly in a desperate situation. At a critical moment, the Five Elements Spiritual Root hidden in Ling Yun's body unexpectedly awakened, and Su Muyao also understood the secret technique of ancient runes. They work together to defend against the enemy, use the Five Elements Sword Qi to defeat the demons, and use the psychic runes to trap the enemies, only to discover that there is a conspiracy of the Ten Thousand Demons Palace hidden behind the mountain god.
This seemingly accidental medicinal trip was actually a trap that had been laid long ago. Only by sharing life and death and breaking through their own limits can the two survive in the desperate situation of the Immortal Mountain. They must also prevent the spread of the magic flame and protect the peace of the world of immortality.
