Waking up from a night of sleep, entomologist Russell found himself transported to the world of beast taming, where he became the owner of an insect-themed pet store. In this world, although insect-type pets are widely distributed, they are often considered “lacking cultivation value” due to their insufficient individual strength and are rarely favored by professional beast tamers. With his unwavering passion for insects, Russell awakens a talent called “Cocoon of Evolution,” which allows insect-type pets to grow infinitely. With a team of underestimated insect-type pets, such as the enigmatic Death Moth, the indomitable Sword Mantis, and the timid yet reliable Camouflage Worm, he sets his sights on clearing the Eight Great Dojos, challenging regional leagues, and establishing his own insect-type gym, embarking on a journey to restore the glory of the insect kingdom!
