The human race declined, the demon tribe invaded the Nine Provinces, and Linhai City became the last line of defense. Only Chen Fan survived among the 100,000 divine warriors. He awakened the dragon spirit of the human race and guarded the lonely city alone. On the way, Chen Fan meets Ji Yao, who is of the bloodline of the Human Emperor, and the two work together to gather the power of the human race. While fighting powerful enemies such as the Dog Clan, Sirius, Golden Tiger, and Dragon Clan, they also eliminate the prime minister and undercover agents who collaborate with the enemy. After a bloody battle, Chen Fan broke through the shackles of his martial arts, and finally killed the demon ancestor Ao Guang and restored the human race's country.
