Lin Zhao, a young Dharma cultivator at Xuanqing Temple in Qingqiu Mountain, entrusted me with the mission of "guarding the human world" before his death. During the Tianqing period of Great Chu, natural disasters broke out continuously - droughts thousands of miles away, floods that submerged cities, locust swarms that blocked the sky, epidemics that swept through counties, and even blizzards in the cold winter that closed the city... There was an evil atmosphere behind every natural disaster. With the magic of controlling water and earth, exorcising evil and eliminating epidemics, I work on the front line of disasters: I divert rain for drought-stricken people, but the rain diversion technique backfires and vomits blood; I build embankments for flood-stricken cities, and use my own spiritual energy to support the embankments from collapsing; In the process, I met Su Wan, a female historian who records disasters. She helped me collect data on natural disasters and exposed the truth about the hoarding of food by the powerful and the corruption of officials. I also encountered the distrust of the people - some people said that I was a "monster", and some called me "nosy". ", But I always remember my master's words: "Immortal magic is not for immortality, but for protecting people." As the natural disasters intensified, I discovered that all of this was caused by the loosening of the seal of the ancient demon emperor, and the "disaster stars" under the demon emperor were awakening one by one. In the end, I led the disciples of the Immortal Sect, ordinary people, and even the powerful people who were once hostile to me, to jointly fight against the ultimate natural disaster - the "catastrophe of annihilation" in which the sky collapsed and the earth shattered, and I used my life to protect the last hope of the world.
