About 6,000 years ago, 72 demons gods put an end to humanity's reign. In an effort to safeguard the human race, the Alliance of Temples was established. However, the threat of demons still looms large. Long Hao Chen, a nine-year-old, trains in the Knight Temple Hall and alongside his friends, he clears the knight exam. After undergoing the Holy Resurrection Ritual, Long Hao Chen discovers that he possesses an enormous spiritual capacity as a Son of Light. Recognizing his potential, Long Xing Yu becomes his guide and encourages him to become a powerful knight. Despite being faced with innumerable obstacles, Long Hao Chen may very well be the one to take down the Demon Lord and herald the end of the dark era.
