In the demon village once every decade, the heavenly light ascends. The whole village is desperately cultivating, except for A Ji, an orphan trash with no cultivation who is stepped on underfoot. On the night before the heavenly light, he dreams of holding a sword and fighting against the upper realm beings that devour all demons. Three days later, the heavenly light truly opens, and all demons cheer and ascend, but A Ji witnesses with his own eyes everyone dissolving and dispersing in the holy light, and a huge golden eye slowly opens deep in the firmament. That is not heaven, it is a cafeteria. A homeless man holding a rusty sword throws him a broken sword, "The upper realm uses ascenders as food, you cannot stop it." But A Ji picks up the sword; the rust peels off, and a golden light suddenly appears. Trash? No. He is the only bone the upper realm cannot bite.
