The distant black witch disaster may have passed many years ago, but now, there seems to be signs of reappearance, and the girl embarks on a foreseeable future. Who will be destroyed first? This is a topic that remains unchanged for thousands of years. And the Demon King's Disaster will be the end of these despicable people. You are me, I am you, and you will be reborn with me.
