Cybernetic Beast Taming In A Game-like World Novel

In a world where technology resurrected extinct magical beasts, David finds himself reincarnated as Jethro Merrick during a Hatching Ceremony. He receives the lowest-ranked egg and must navigate life as a poor mechvet's son, yearning to become a Riftwalker—someone who tames cybernetic beasts and explores dungeons. When his egg hatches into a powerless Red Lizard fit only for pest control, Jethro's dreams seem dashed. Everything changes when a wrong turn during a training expedition leads him into a forbidden Rift zone. Barely surviving, he awakens with an extraordinary ability: he can perceive the magic and mechanics of every mechbeast, tracing them to their origins. This power comes with a dangerous price. An ancient conqueror who once possessed this ability seeks to reclaim it, commanding a formidable army of terrifying mechbeasts. To survive, Jethro must build his own army, beginning with his seemingly useless pest-control lizard. Now, a rookie with a powerless creature must somehow save the world of Nebulon from destruction.
