Transmigration: I’m Not An Omegina!

Silver-Winged Snake Beastman Owen was wandering when he accidentally saved a heavily injured Omegina; he happily brought the person back to prepare for mating. Before he could even touch the Omegina, Owen was thrown over the shoulder by him. Owen lay on the ground, staring at the deep blue sky, feeling his worldview crumbling. Aren't all Omeginas supposed to be very weak? Aren't all Omeginas supposed to be very timid? Why is the future mate he found so ferocious? ... Rowan was a top-tier Alpha during the era of interstellar warfare; during a battle, he accidentally transmigrated to a strange world. While struggling to survive, Rowan was mistaken for an Omegina by Owen, who rescued him with the intention of laying eggs together. Rowan had screamed no fewer than a hundred times: I am not an Omegina, I am not! Unfortunately, no one believed him... ... *World Setting: 1. Rowan's original world: The Mecha Era, set against the backdrop of a war with the Insect Race. There are three genders in this world: Alpha, Beta, and Omega. 2. The world Rowan transmigrated to: A primitive Beastman world with two genders. Beastmen can transform into beast forms for combat. Omeginas are similar to male Omegas in Rowan's original world: frail and capable of reproduction. 3. Forms of address for parents: Beastman fathers are called "Daddy". Omegina fathers are called "Papa". ... *A few words from the author: This story mainly revolves around the courtship journey of the Silver-Winged Snake Beastman Owen. It contains elements of war, tribe building, and civilization construction; however, these are not explored deeply, so please do not expect too much. There may be many inconsistencies, so I hope for your understanding. Happy reading!
