Taoist Priests and Demons

My father is a shark, a demon. My father is a Taoist priest who eliminates demons. Dad has liked my father for a long time. He took advantage of his weakness and ran away when he fell asleep, and then he carried me in his belly. Dad said: "He is cruel. We must not let him know about our existence. He will eradicate us." I always thought it was a lie, but one day, Dad disappeared. The father went to the door with his sword in hand. He held a bloody scale in his hand. Intention: If you have something to say, don't hold it back
