In District 9, Xiao Yi, an aristocratic boy, offended the powerful because of his arrogant character and was exiled to a heavily polluted slum. In despair, he accidentally awakened Tang Monk's bloodline, bound the sutra acquisition system, and was able to absorb the fragments of scriptures scattered in the ninth area to obtain magical skills. He hides his strength, pretends to be a pig and eats the tiger in the slums, uses a tight spell to subdue his two-dimensional younger brother, and collects fragments to unlock the true form of Jin Chanzi. As his strength increased, he uncovered the truth that District 9 was a two-dimensional prison created by an alien civilization. He proudly chose to protect this land, and eventually became a holy monk in District 9, leading everyone to resist.
