Being an Eel and Being Named the God of the Abyss

I traveled through time and became a larval eel. Transparent and fragile, with only one black digestive tube exposed like a dotted line. The system told her: You will grow into the God of the Abyss in three years - but the sea level will skyrocket within three years. If the god is not enthroned in time, methane will explode on the seabed and all fish will become extinct within 72 hours. From the Sargasso Sea to European freshwater rivers, from fishing nets, plastics, herons to snakeheads, dams, and farms - every escape is an extreme survival, and every meal may be the last meal. I want to complete the eight years of development of a normal eel in one year, dominate the fresh water, and then migrate thousands of kilometers in reverse direction to the unwitnessed gate of the abyss. This is no ordinary doomsday survival. This is the tragic migration of eels, a cruel sketch of ocean pollution, and a wild history of gods written with slag and slime. I can't fight, I don't have magic, I just slide, squirm, and secrete mucus. But I want to save the entire sea. Read warning: The book contains a lot of real facts about eels, the dark history of psychologists, philosophical remarks from cats, and plots that may make you cry next time you eat eels.
