Zone Zero: the Black Cat Who Emerged from the Fall of the Old Capital

The world's strongest killer, Black Cat Jinpen, washed his hands and became a gamer. However, the moment he pressed the mouse button when the Zero Zone Zero server was launched, the space he was in instantly turned into a void and swallowed him directly. When he woke up again, he found that he was twelve years old, and in front of him was... Hell on earth. Countless monsters raged on the streets, people screamed and ran around, and the smell of blood and gunpowder filled the air. Just when all this is about to awaken his instinct... "Captain! There are children here!!" "Damn, cover fire, I'm going to save him!!!" ······ "Zoe, please... This child and her are all left to you... You must get out alive!"
