Su Lin, a cold-hearted forensic doctor who has never believed in ghosts and gods, discovered that all the clues pointed to the non-human "murderer" while dissecting each of the strange corpses. At the same time, বারবার, an online writer who specializes in the Classic of Mountains and Seas, provides her with precise ideas for solving the case as a "reader" and guides her towards a "world of strange beasts" covered up by modern civilization.
As the investigation deepened, the mysterious bloodline in Su Lin's body unexpectedly awakened. She discovered that not only could she see strange beasts that ordinary people could not detect, but she could also establish spiritual links with them and even command them. It turns out that her quiet and cold temperament was a form of self-protection formed by her bloodline power to avoid losing control.
When she began to accept her abilities and contracted her first alien beast, a mysterious transnational organization called "Chimera" surfaced. The organization is committed to capturing, studying and even fusing alien beasts in an attempt to create the most powerful biological weapons. Su Lin's special bloodline has become their most desired target.
With the help of Wen Jingci, Su Lin used forensic knowledge to solve unsolved urban cases caused by alien beasts and rectify the names of innocently implicated alien beasts; while constantly conquering powerful alien beast partners, improving her strength, fighting wits and courage with the "Chimera" organization, smashing their plots one after another, and finally uncovering the ultimate secret of her bloodline and the truth about her parents' disappearance.
