Evolution Through Devouring, Starting as a Sparrow

Aren't angels just birdmen?

It will take at least ten chapters to read

. . . I think writing this kind of book should not be too fancy. Few people who are good at this kind of writing have turned back into humans. They have evolved through devouring. If you become a human, you have to evolve. You might as well practice. Devouring evolution is mainly about the body. A level 2 sparrow threw away its only attack skill and asked for a skill that increases eyesight. In the end, it actually won the snake. The sparrow's claws and beak did not break the snake's defense at all. Even if it evolved once, wasn't the snake a monster? Such a dish?
