Apocalypse Beast Taming: I Survive by Hiding in Another Dimension

Ten years after the Star Abyss invasion, Blue Star has fallen. Li Chongsheng has survived for ten years in the ruins of the Seventh District, not thanks to any extraordinary ability, but to a mysterious spirit companion of unknown origin—it can't win any fight, but it has a passive talent: when facing lethal danger, it drags its master into another dimension. In short, it's just fast at running away. Until one day, he finds a glowing metal fragment deep in the ruins, and the silver patterns on his spirit companion's forehead light up in response. Then, a woman wearing the Star Abyss Spirit Envoy uniform descends from the sky, riding a spirit that shouldn't exist in this world. "Your spirit wasn't created by Star Abyss technology." "It belongs to this world." "And you, Li Chongsheng—you are the first of the twelve keys." From that day on, he no longer just 'survives'. — Description from novelcodex.org
