Ten minutes later, the space next to the corpse of the invisible man suddenly started flickering, and a man identical to the invisible one appeared from the void.
The man looked at the corpse with a complex expression and murmured, "The boss's premonition was indeed accurate; the trip to Dragon Country was indeed perilous! If I hadn't mastered the Life-Sacrificing Puppet Technique, I might have fallen in Dragon Country today."
The man spread his hand, revealing a metal object in his palm that roughly resembled a mosquito, this mosquito-like thing had a sharp proboscis.
Squeak, squeak...
Suddenly, the mosquito-like object began to flicker and flew into the invisible man's pocket; soon after, it flew back and landed in the man's hand.
The tip of the mosquito's proboscis turned faintly red, dripping out a drop of blood-like substance.
