In a dead world called "Xu", everything is dust, only the "soul fire" is immortal. Mortals who light the soul fire can embark on the path of spiritual practice and are called "fire-burners." Young Lin Changgeng was born with a dim soul and was regarded as a useless person, living in a forgotten corner of his family. By accident, he mistakenly entered a forbidden area and found an ancient bronze lamp that could absorb the soul fire of others after death. From then on, he embarked on a path of swallowing soul fire and changing his fate against the will of heaven. However, he gradually discovered that behind this lamp, there was hidden the ultimate secret of the death of the whole world, and he was just the spark chosen to light up the end in the long river of time.
