Apocalyptic Turnaround Battle

The earth shook, and Ye Wan grew a pair of cat ears. When she was horrified, she found that everyone had changed, rabbit ears, antlers, tiger teeth, scaly skin... Eyes full of monsters from fantasy movies? Orcs? ! Oh my gosh! This must be a dream! Ye Wan pinched herself hard. The pain was real! Suddenly, she saw an orc with a mouth full of fangs biting the neck of another orc in one bite... Blood is everywhere and killings are everywhere! This is the end of mankind, and the battle for survival is imminent! ~~The pink and tender little seedlings, please take them away! O(∩_∩)O~~
