In the near future, a global ecological disaster called "The Gray Tide of Death" breaks out. It is not a virus or radiation, but a flow of corrosive and assimilative microscopic particles of unknown origin. After the gray tide, 90% of animals and plants became deformed and became "aberrant". The land and water sources were polluted, conventional crops could not be grown, and human civilization collapsed. The survivors huddled in a few cleansed areas or ruined cities, struggling to survive.
In the final battle, the "Liaoyuan" feast cooked by Lin Su not only greatly enhanced his own combat effectiveness, but the life energy fluctuations contained in it also unexpectedly affected the aberrations, purifying the weak aberrations and disrupting the powerful aberrations, which relieved Chen Mo's huge pressure on the frontal battlefield. In the duel with Xiao Yang, Chen Mo finally defeated and ended Xiao Yang with his stronger will and the blessing of "Liaoyuan". The Black Wind Regiment was leaderless and completely defeated. After the war, although Oasis made sacrifices, its cohesion was unprecedentedly strong. In the last scene, Lin Su and Chen Mo stood on the watchtower, looking at the smoke rising from the kitchen, the expansion of the fields, and the homes where children were laughing. A new motorcade appeared on the distant horizon, symbolizing the continuation of hope and the reconstruction of civilization.
