Wander Freely Through All of Time and Space? I'll Conquer It All

[Ruthless and decisive + space-time powers + high-energy power fantasy] After an accident, An Xia gained the ability to travel through time and space. He watched Ruola fall into a pool of blood to save him, helpless to change her fate. At the critical moment, he awakened his space-time travel ability once more. He had only one goal: become stronger, then stronger still, until he could reverse life and death. He transmigrates to a late Qing-era escort agency and learns internal cultivation techniques. He arrives in the future’s New Demon Capital and completes extreme body tempering. Hunters come after him? He wipes them all out. The Time and Space Administration schemes against him? He beats them into submission. When everyone thinks he knows nothing but cold-blooded killing, he tears through parallel worlds and slaughters the space-time hunters for a girl he barely knows, Lin Xi. “You saved me twice. This time, it’s my turn to protect you.” The moment Lin Xi stood in front of him, a corner of his frozen heart had already begun to melt, though he didn’t know when. But this world is far more complicated than he imagined: ancient space-time civilizations, abyssal rifts, and hunters at the level of rulers... Faced with ever-stronger enemies, he has only one response: Roll over them. That’s all there is to it.
