On the planet of Iris, where elves and humans coexist, Lin Ye, who comes from a declining family of spiritual masters, was once regarded as a loser. In an accident, he awakened the ability to sense star marks, established a bond with the young fire-attribute elf Yan Ling, and embarked on the road to become a spirit master. In the academy, he attracted much attention because of his special abilities. He also discovered the "Star Mark Prophecy" and realized that he had a great mission.
In order to improve his strength, Lin Ye went to the Star Trace Secret Realm to practice. On the way, he encountered contaminated elves and met Irene. After that, they discovered that the top management of the college was actually a minion of the villain Caesar, who tried to use the power of Star Trace to rule the planet. Lin Ye continued to grow with the help of Golden Finger, and joined forces with his partners to form a resistance army to start a decisive battle with Caesar. In the end, Lin Ye understood the guardian power of Star Mark, purified the polluted elves, and defeated Caesar. But the source of Star Trace pollution is still there. He embarked on a cosmic journey to find a solution. After returning, he passed on the knowledge and successfully solved the pollution. However, he exhausted his power and turned into starlight and merged into the planet. His story inspired countless followers.
