Reborn as a Beetle in the Immortal Realm

The main character was an average man in his past life who had a deep, hidden desire for power, which was suppressed all his life because of the rules of his past world. Now reborn as a beetle with the potential to challenge the heavens in a world where the law of the jungle reigns supreme, he can let this deep desire fully emerge, which will help him survive and thrive. Because the main character is reborn as an insect, he doesn't have a strong affinity with humans. To make matters worse, immortal cultivators have a deep hatred for magical beasts as they are eternal enemies, which will lead the main character to be seen as a villain by the humans of this world, and with his ability that needs him to devour other life forms to grow, his position as a villain is evident.
