Violent Collection? I Use My Backhand to Awaken the Super Powerful System and Smash It

After encountering violent debt collection, I obtained the system and smashed the man-eating company with my backhand. However, I was "recruited" by the Superpower Management Bureau and gradually became their sharpest knife. But my true rebirth started when I joined the "Z" team. Here, I found comrades who I could trust with my back. We are a whole, and my life is tied to theirs. We fought against the darkness entrenched in the city, humiliated the sanctimonious director in public, and ripped apart his disguise during the live broadcast. But we soon discover that the corrupt magnate is not the only enemy; When the tide of beasts that can flood the city comes without warning, and when the unfathomable wormhole opens outside the city and spits out unknown horrors... Then we know that the world is falling into deeper darkness. And my team and I will hold each other's hands and fight against this increasingly crazy world for the shaky lights behind us and for everything worth protecting. From one person's revenge, to the symbiosis of a group of people, to fighting for the survival of the entire world. This is our story.
