Lin Yan, who was born with "pure yang eyes", has been able to see yin and yang since childhood. From the first manifestation of supernatural powers in Qingwa Lane in Jiangnan to becoming a disciple of a reclusive Feng Shui master, he embarked on the path of metaphysics. Along the way, he resolves strange things, fights against evil spirits, and shoulders the important task of strengthening the seal of the "Lord of Evil". In the end, he grows from an ignorant boy to a master of the world.
