Honghuang: Trapped in the Depths of Chaos, with a Demon God Next Door

I wake up floating in the chaotic void. There is no up or down, no left or right, no hunger or exhaustion. Once I confirm that this is the origin of the Primordial World, the countdown to Pangu's creation of heaven and earth begins. In my previous life, I was an orphan and got used to being alone. In this dim, gray expanse, there is only me and the three thousand Demon Gods who have yet to awaken.
