Chapter 423 To Trade in Cat’s Blood

• In a dimly lit room, the cat restrained for blood extraction suddenly convulsed and struggled. Its body twitched violently, kicking a tray placed next to its feet and sending it flying.
• The tray contained some blood extraction tools, such as needles and blood bags, which clattered onto a nearby cat cage.
• In the room, there were more than a dozen cats. Some of them were frightened by the convulsing cat and cowered in the corners of their cages, hissing with bared teeth as their eyes filled with terror.
