In a wasted plain that bears the scars of a fierce battle stands two horrific figures, one of them is a monstrous red Demon that emits no lesser aura than the strongest Demons. There was a glowing mark on his forehead, containing a power of ancient damnation.
His hand rested above the mark as his eyes widened in horror.
Realizing that the Slave Mark branded onto him was activated struck his demonic soul.
Without the presence of higher beings, the mark should've remained dormant.
Even then, the reality that the Slave Mark was somehow activated couldn't be denied, and his eyes unconsciously shifted back to Flunra who was already putting on a devilish look, enjoying Demon Lord Kirgil's petrified expression.
Flunra's smirk clearly indicated that he was the one responsible for this weird occurrence.
Turns out, the experiment he was talking about is not nonsense.
