Bloodline Awakening: Asylum Temporary Worker

[Introduction to the work] Chengbei Asylum is an institution that is listed in the municipal directory but has never been included in any official document. Su Mu works as a temporary worker here, collecting cats, registering cats, and working the night shift. He commutes to and from get off work on time like all clerks. He never asked himself why - the father's column in the household registration book was empty, and he couldn't remember his mother's name. My whole life was light and airy, as if I could be wiped out from this street at any time. Until that day, he rescued a dying black cat in the backyard of the shelter. The cat is alive, and there is a panel in front of him that does not contain any official documents. It doesn't shout or yell, it only dances one line when it's time to jump: External threat, vital signs, bloodline, not detected. From that day on, everything inside and outside the asylum door changed. There were more footprints in the night shift's backyard, the wall looked like blood, and the red and black mark on the inside of his wrist began to dance. It dances to the same rhythm as the green light on the tip of the black cat's tail. Someone has been outside. They didn't come in, they just stood on the street corner, counting how many times he had returned home over the years. Ma Liu only told him half of what she said, the other half - to him. A key to identify his father, and a key to identify his mother, each hung up for decades without a sound. The key recognizes blood, and blood recognizes days. The day will come when he feels he can protect himself. And what he wanted to protect was never a cat. [Protagonist] Su Mu, 24 years old, is a temporary worker at a shelter in the north of the city, guarding a black cat named Briquettes. [Status] In series, updated daily.
