Global Evolution: I, Scar Carp, Eat as a Taboo

I was once a human being who was betrayed and pushed to the bottom of the river. When I opened my eyes again, I became a carp with a scar on its forehead in a plastic basin in the market, waiting to be put into the pot. There is no system of travelers here, only the bloody fish tank rules. The arapaima is the overlord, the alligator gar is the executioner, and I am... A piece of meat in the eyes of all predators. But I found that I could eat it. By eating a scale, I gain steel defense. Swallowing a piece of meat, I plunder the deadly ferocity. Under the selfie lights and the barrage of onlookers, I survived, lurked, and fought back in the fish tank of death. From a piece of meat, I became a nightmare for all predators. They call me "Scar Carp" and jokingly call me "tank bully". Until that day—— Meteors fall from the sky, spiritual energy revives, and the world evolves! Cities are disintegrating due to the wild growth of plants, and animals are becoming giant due to genetic atavism. The civilization that mankind is proud of has been reduced to wilderness overnight. And I jumped from the broken fish tank into the flooded city. Among the neon lights and ruins, I saw natural enemies that evolved into nine-headed pythons, and saw the ancient bloodline awakening as towering as mountains. Evolutionaries all over the world rank me as the highest threat because I follow the most primitive and terrifying laws: Everything you see is edible. Everything you eat is mine. I eat from rivers to oceans, from cities to secret places. Every ancient bloodline I swallow pushes me to the top of the life map. When my huge body covered with dragon patterns rolled over the ruins, all living creatures were shocked: The "Scar Carp" that they once watched, placed bets on, and teased has become the only living taboo in the era of global evolution... On its way to devouring the world.
