Yun Heng was originally a disciple of Qingxu Temple on Taihua Mountain. He studied Taoism at a young age and had a peaceful mind. A mysterious celestial phenomenon dragged his soul into the mortal world thousands of years later. He was trapped among steel and concrete, and his spiritual energy dissipated, making it difficult to continue his Taoism. In the new world, the world is hot and cold, all living beings are noisy, and people's hearts are even more unpredictable. Yunheng entered the world of mortals for the first time. He just wanted to find his way back and return to the old view of Qingshan. However, he accidentally touched the suffering and desires of modern beings and witnessed the confrontation between technology and Taoism. Faced with immortal magic that could no longer be used and an endless stream of magical weapons in the world, Yun Heng gradually realized that "the Tao never leaves this world, and the Tao exists in all living beings" between being lost and awakening. When the ancient ideal of cultivating the truth encounters a modern ethical dilemma, should Yun Heng stick to pure inaction, or blend into the world of mortals and find a new understanding of Taoism? This book uses classical writing methods to outline the collision between the past and the present, explores what it means to "become an immortal" and what it means to "be a human being", and write an unprecedented legend of cultivation in the chaos of the world.
