The Contract Between Yuan Soil and the Inheritance and Choice of Qing Soil

An extended creation based on the world view and core settings of "Owl Rises": Under the boundary between light and darkness, the ancient contract is collapsing. Lin Wan, a researcher at the museum, was forced to get involved in a thousand-year war between humans and underground monsters called "owls" because a jade cong from the Han Dynasty awakened the bloodline of the earth-keepers. When she discovered that Wuying, the leader of the radical faction of the Xiao tribe, was trying to break the contract and return to the world, she had to form an alliance with the explorer Lu Chen who was looking for her brother's whereabouts. Going deep into the treacherous underground world of green soil, faced with the choice between the survival of her race and the fetters of humanity, Lin Wan gradually uncovered the ultimate secret of her own bloodline - she is not the guardian of the contract, but the only key to whether the two worlds can coexist. When darkness engulfs the world, she must make a choice: to be the dawn of salvation or the abyss of destruction? (Note: This is a fan-made derivative work based on the world view of "Xiaoqi Qingyang", and the story is rewritten while retaining the core settings)
