Interstellar Zerg? Crunchy

Republic 4102, the scientific research ship "Pathfinder" disappeared at the edge of the galaxy. The last message sent by the spacecraft to the universe was: "We may have discovered a brand new civilization." One standard year later, the Zerg invaded. Soon, the illustrious Galactic Republic fell apart under the impact of the insect wave. … Fifty years after the split of the Republic, Jiang Feng came through. In the beginning, he was just a little waiter on the starship. Like other low-level citizens, he had neither expensive enhanced prosthetics nor outstanding genetic abilities. He did not go to the temple to learn telekinesis, nor could he drive a starship invincibly. But he soon discovered that he could actually upgrade and strengthen himself by devouring the Zerg. In the face of the insect tide, the human front made frequent mistakes, struggling to hold on, and succeeding one after another. Even though they were defeated, they were still glorious. Also facing the insect tide, Jiang Feng ate a lot, the more the merrier, simmering, stewing, frying and frying! The Zerg eat more and more, and Jiang Feng's power becomes stronger and stronger. Looking back on his journey, he has become the first scavenger of the galaxy and the universally recognized expert on Zerg taste.
