Was there a novel about the war between humans and the Zergs in the interstellar war, and that humans could cultivate?

Please give me the name of a novel. Interstellar War was a war between humans and Zergs. In it, humans could cultivate a technique that allowed them to grow saplings of one level per leaf. In the later stages, the protagonist discovered that the reason for the Zergs 'evolution was caused by an evolution pod placed by an alien life form. The protagonist used another evolution pod to create several children.
The main storyline wasn't about the Zergs, but about the protagonist's cultivation and exploration of the evolutionary path step by step.

Answer 1

" I recommend the novel " Interstellar Biological Empire " to you. The plot of the novel includes the development of biotechnology, the improvement of the environment, and the content of migrating to the galaxy. There is also the plot of humans being able to cultivate and use biological mecha to counterattack when facing the invasion of the Zerg. I hope you like my recommendation.😗
