To make his self-destructing beetles unleash greater power, Huo Hai could only find ways to enhance the force of their explosions. The beetles themselves could not be improved; after all, they were already Gu Insects.
As Gu Insects, and since Huo Hai had never considered anything else when refining them, these beetles still looked like ordinary beetles, yet they had actually lost the ability to continue advancing. Even now, Huo Hai lacked the ability to refine such high-level beetles again and raise the rank of the Gu Insects.
