In the first year of the apocalypse, a "spiritual tide" broke out across the world - the fall of immortals and demons on the battlefield caused catastrophe, and mutant beasts and evil cultivators appeared in the city. In order to protect his sister Lin Xiaoxia, Lin Chuan unexpectedly obtained the inheritance of the Shangqing sect from the reclusive Taoist Zhou Xuanqing and embarked on the path to immortality. From a weak commoner in the early stage of Qi training to an urban swordsman who can fly with a sword, he has experienced the fear of fighting strange beasts, a life-and-death battle with evil cultivators, and the sacrifice of his guide, and gradually understood that the true meaning of immortal magic is "protection". In the end, he united the survivors and decent monks to destroy the amethyst pillar at the core of the disaster, shut down the tide, protected the "safe city", and became the guardian of the city.
