Scientific Research Unit Five building front entrance.
Xu Yi saw the "vampire" that Martin mentioned, and he recognized the person, a security guard at the gate.
Of course, the security of Blood Research Five couldn't rely on these Common people; their duty was to turn away students who wandered in by mistake.
At that moment, the person was lying on top of another security guard, two sharp fangs protruding, fiercely biting into the prey's neck, greedily sucking the fresh blood.
The "vampire" sensed movement behind it and turned its head abruptly, its pitch-black pupils revealing a faint blood-colored Reverse Cross.
Xu Yi was startled; he suddenly had the illusion that what stood before him was an Undead Evil Deity resurrected.
More and more shadows gathered, and Xu Yi glanced around, counting at least eight, each with pitch-black skin and blood-colored Reverse Crosses in their pupils.
