With the experience of identifying medicines by light transmission, Chen Zhou picked up one of the syringes, adjusted the angle in the same way, and looked for a while. Apart from the bright sunlight, he saw nothing.
"That's not right, could this syringe be a mystery box?
This damn thing doesn't specify its use; who dares to just inject it? At least explain the method, whether it's blood injection or muscle injection..."
Chen Zhou had already cursed the Space-Time Administration Bureau in his heart. Paul, beside him, suddenly tugged at his sleeve lightly, signaling him to look inside the box.
Looking down, he finally noticed that under the syringe, there was a narrow slit, with a piece of paper about 5cm long standing upright in it.
