On the third day when radiation dust covered the sky, all supplies were looted. Xuan Qian huddled in the collapsed underground shopping mall, hearing the roar of the mutant beasts getting closer and closer. What oozes out from the cracks is not an ordinary mutant beast, but a B-class ferocious beast that can tear apart steel - he only has six hours left, and this place will be razed to the ground in six hours.
Just when he was about to accept death, the mutated beast egg dug out of the ruins in his pocket suddenly cracked open, and a cub covered in black scales opened its vertical pupils and directly inserted a sentence into his mind with his consciousness: "Your heartbeat is very noisy, I will lend you a life." From this moment on, he could sense the killing intent of all creatures within a hundred meters, and the mutant beast that should be feared by humans was teaching him how to hunt in the ruins in its own way.
But what he didn't know was that the cub's real name was engraved on the forbidden book list of the old era. Every time it evolved, it was one step closer to the collapse of the balance of the world. When the forces of the military, the consortium, and the mutant beast royal family all targeted him at the same time, Xuan Qian finally realized that what he was contracting was not a pet, but a nuclear bomb that could detonate the world at any time.
