Biologists Travel Across Douluo Continent

This is a world with a locked evolutionary path - hunting soul beasts, absorbing soul rings, becoming a titled Douluo, and inheriting the divine throne. Every step is written on an established track. Life should be open, trial-and-error, and adaptable, but here it is forcibly divided into nine levels. And I, a biologist who traveled through time, hold a weapon called a "microscope" in my hand. I decided to let the world learn to evolve again.
