Honghuang: Bound to All of Humanity, as the Demon Race Attacks

I transmigrated into a tiny human Nascent Soul just as the final battle between the Witches and Demons was about to begin. The Demon Race was forging the Witch-Slaying Sword and planned to sacrifice hundreds of millions of humans to Heaven. I activated the whole-clan System on the spot, binding myself to 76.3 billion clan members so I could passively receive a share of the cultivation gains of all humanity. But before I could even enjoy it, I looked up and saw demons descending from the sky.
