Invasion of Disaster Insects: Parasitic Cultivation

This world is parasitized. I don't know when the plague began to invade people's lives. They parasitize in the bodies of practitioners and immortals, absorb magic power, nourish themselves, and thus multiply endlessly. Even powerful mana and advanced cultivation are unable to stop the plague insects from parasitizing. If we can deal with the alien species outside, what should we do with the creatures inside our body... When the whole world was almost in despair, a girl protected by the plague insects appeared. Xu Qingyu has no cultivation physique. She should have lived an ordinary life, but she discovered the possibility of symbiosis between humans and plague insects... Even plague insects can absorb the power of heaven and earth and become immortals. This is a parasitic fairy tale about a girl and an alien.
