My Sister Traded Her Stupid Snake Fetus for My Genius Shark Cub

The shark cub I gave birth to will be able to howl at the moon within three days to warn of danger approaching. However, even the most basic identification of the cub that was born from her sister's affair was difficult to do. The sister is jealous. She poisoned me, causing me to die from intestinal rupture. When I opened my eyes again, I went back to the day of delivery, when the midwife inserted a silver needle into my Baihui point. While I was unconscious, my sister exchanged her stupid beast cub with my smart beast cub. I endured the pain to create opportunities for them, and personally offered the position of Young Master of the Shark Tribe. Just because I know that after that, the Shark clan tried to seek power and usurp the throne, but they were completely annihilated by the dragon clan, the leader of the orc clan. The young master of the Shark tribe was forced to have his inner elixir removed, and was tortured by thunder and lightning that cut out his heart every day. Now a scapegoat is coming to your door. If you don't change it, you won't change it.
