The soul of Su Chen, a modern Journey to the West journey, traveled to the ancient times and became an orphan of the pure-blood human race on the border of the Tang Dynasty. He has no bloodline and no backing, but he awakens the sacred heart of the human race, inherits the "Prehistoric Human Race Secrets", and starts a counterattack on the road to enlightenment. He is familiar with the plot of Journey to the West. He seizes opportunities in advance, slays demons and demons, slaps immortals and Buddhas in the face, borrows sutras to measure his fortune, soars from the first level of Qi refining to a quasi-sage, and earns the dignity of the three realms for the human race. On the way westward, he rescued Ling Qingyao, a holy girl from the Kunlun fairy tribe who was being hunted by heaven, and met Su Qingyue, a human medical fairy who lived in seclusion in the Medicine Valley. The two heroines ran in both directions and accompanied each other side by side. The three of them joined hands to break into the secret realm, resist the disaster, and solve the conspiracy. Su Chen used his human body to protect his loved ones and protect the common people. In the end, he took the two immortals to escape the three realms, leaving behind a legendary story of the supreme human race.
