I Became a Lion

From a stumbling lion cub to a majestic lion king. He originally thought that the vast territory, the dominance of the grasslands, and the fear of enemies would be the climax and end of a lion's life. Unexpectedly, the lion's life has just begun. The earth's energy mutates, various mutated creatures attack, humans fall from the top of the food chain, and the African grasslands are also in crisis. And he is also gradually becoming stronger through evolution and mutation.
