A science and engineering guy is reborn as a Siberian tiger cub, drifting onto the African savannah and unexpectedly adopted by a mother leopard. When attacked by hyenas, he cleverly uses mechanics-based footwork to drive off the enemy, and relies on elastic potential energy to set traps and drill wood to make fire for roasting meat. The aroma of the meat attracts covetous beasts, and he uses the terrain, quicksand, and the lever principle to subdue wild dogs and hyenas, establishing a savannah hunting corporation. He also uses the law of inertia to toy with and defeat the old lion king, thoroughly achieving legendary status. Unexpectedly discovered by human researchers, he builds a giant slingshot to precisely shoot down a reconnaissance drone, directly subverting human cognition!
