Lu Chen was clearly only prepared to drop a single droplet of his vital blood.
Yet as the blood touched the bottle, the jade vessel suddenly produced a massive suction force!
The small cut on Lu Chen's finger unexpectedly widened, and his vital blood was drawn out as if spurting from a fountain!
"Not good!"
Lu Chen let out a cry of alarm, cursing inwardly for falling into the trap of the Clean Jade Vial!
The space inside the Clean Jade Vial was vast.
At the time, even an entire Dragon Scale Beast couldn't fill it up, let alone his own blood!
However, what Lu Chen hadn't expected was that the suction force of the Clean Jade Vial wasn't absorbing his blood into the vessel itself, but was instead causing it to adhere to the surface!
Lu Chen breathed a sigh of relief, for if it was merely covering the surface of the vial, then that wasn't too bad.
He could grasp the Clean Jade Vial with one hand—it wouldn't use much vital blood.
