The shops along the street are closed, the lights of the residential buildings are all turned off, and only the dim street lamps cut the narrow street into a strange form of light and dark. Zizi ...... Zizi ...... After a burst of electricity, the four-character sign "Holy Relic Clinic" lit up in the darkness. Zizi. There is only one "Don't" left on the signboard, like the red light of the siren, flickering uncertainly. Zizi. The word "忄" lit up with difficulty and was at the forefront of the signboard. In the darkness, the word "monster" kept beating and beating like a flame...... All the earth is extinguished. The glass door panel under the signboard shook gently, as if there was an invisible person entering the clinic.
