I Was Three After Being Reborn in the Apocalypse

[Blurb] Shen Xin was reborn from the third year of the apocalypse to its very first day. She went from being a human walking arsenal at a base to a three-year-old toddler. Her former neighbor, a grizzled soldier she'd parted ways with, tucked her inside his coat and protected her like a treasure. Shen Xin defiantly pulled an RPG out of her spatial storage: Outrageous! Which one of us is protecting the other? The grizzled soldier Qi Zhao solemnly raised his hands: Xin-jie is awesome, Xin-jie is the strongest. Xin-jie will protect your big brother, right?~ Shen Xin: You never know what might appear from my spatial storage.jpg * Ever since being reborn, Shen Xin has felt that something about this apocalypse is off. Her former roommate keeps asking her for a necklace: I gave that necklace to Shen Xin. It's mine, and the space inside it should belong to me, too! Shen Xin: ??? Fine, fine, you can have it. If you can find the space, I'll admit defeat. The leader of the base from her previous life shows her a strange kind of concern: Xin Xin, don't be afraid. No matter what you turn into, I'll never abandon you. I'll take you away. Just the two of us, to our own paradise. Qi Zhao cracks his knuckles: What's your problem, trying to steal my girl right in front of me? I'll knock you out with one punch! Shen Xin: You two can go fight next door. I'm only three years old and I have no idea what you're talking about. * In August 2030, a meteorite came from a distant star system, bringing a catastrophe that caused biological mutations. Billions of people became zombies. Peace was gone, order collapsed, and humanity's arrogance turned people against one another. In October 2030, humanity uncovered the true secret of the apocalypse. Some despaired, some lost their way, and others took up the last remaining hope. --If humanity is destined to perish, at least let people catch their breath before they die. Shen Xin never imagined that humanity's last gasp would be nothing more than a deep breath. Hope had always been in human hands. She looked at the blue planet. It was wonderful. No one could ever take away its color again. ****Reader's Guide**** 1. Zombies and wasteland. 2. One-on-one romance throughout. 3.
