Guang Xiaoyu always thought her senior brother was a dispirited ordinary person, until one day, his pet cow crushed an entire group of Divine Kings with a single stomp. The black dog opened its mouth and expelled a Sword Qi, blocking millions of the Demon Race. The Earth Chicken that babbled every day turned out to be a descendant of the Ancient Phoenix! Ahhhh! Her worldview collapsed! Zi Ji: “Senior sister, it's terrible! The Demon Emperor is leading an army of millions from the Demon Race towards us.” Guang Xiaoyu: “Senior brother, help!” (This is a story about the Demon Emperor’s rebirth, the Netherworld’s daughter’s reincarnation, the protagonist's pet-keeping journey, and a call to everyone to love and care for small animals!)
