Is Apocalypse III Sequel Necessary To Understand The Ending?

An apocalypse driven by natural disasters. Survival of the fittest. Typhoons, floods, deadly cold, scorching heat, earthquakes, tsunamis, insect plagues, acid rain… After struggling through three years of the apocalypse, Nicole Floyd met a brutal death. Miraculously, she woke up and found herself three days before it all began. Nicole seized the advantage to reclaim her storage space, flipping the switch on full-on stockpiling mode. She shopped until she ran out of money, and her storage was packed tight. She also looked for the dog that had saved her life once before. She sharpened her knives, stacked her supplies, and took care of unfinished business. She paid back every debt, whether owed in blood or in kindness. And then, disaster struck. Her right hand gripping a knife and her left stroking the dog, Nicole pressed on through the ruins of a world without order or morals.

Eight years ago, I was transported into this post-apocalyptic power fantasy novel as the same-named expendable nobody. I had the ability to create a large-scale radiation shield that could block zombies. I was the only S-Rank ability user in the entire colony. But because my younger brother, Samuel Grant, failed to awaken his ability, my only purpose became providing him with "upgrade materials." I tried to fight against the story and refused to hand over my crystal core. But the story's inertia twisted everyone's minds. My parents accused me of working with the Zombie King just so they could forcefully transplant my crystal core into Samuel. My ex-wife, Chloe Carter, went even further. While I was unconscious, she personally cut open my chest and took half of my crystal core. I survived. But my spine was severely damaged. My ability circuits were destroyed. I became a cripple who could never stand again. After I was released from prison, I could only work at a chemical protection laundry plant on the outer edge of the colony. Then, a mutant zombie horde carrying extreme radiation surrounded the colony. The old shield generator was burned out by the radiation. Suddenly, my entire family knelt in the dirty wastewater and begged me. "Ethan, you're the only one who can manually guide the remaining power in your ability to repair the shield! You have to save Samuel! He's still fighting on the front lines!" Sitting in my wheelchair, I pointed at the eight-inch scar across my chest. Then I pointed at my withered legs. "The crystal core is inside Samuel's body. My broken spine is buried in the mud under your feet. I can't even stand anymore. And you want me to go into the radiation zone? Are you hoping to watch me die?"

"Who needs love when I can see the future?" After being betrayed by my boyfriend and best friend, I died and then woke up five years into the past, bound to a mysterious system. The quest my System gave me—just two weeks before the zombie apocalypse—was simple: find the most dangerous man in the city and make him my protector. Unfortunately, that man is a psychopath. A mad dog everyone fears... and the only person capable of keeping me alive. With Foresight, a pocket dimension, and memories of the world's end, I intend to rewrite my fate. As long as I survive him first. (Mature theme present #threesome)

In her past life, Aria was butchered by her sister-in-law and her husband Ethan, died freezing at -40⁰C outside her husband’s luxury villa.

Outside, the sub-zero wasteland is waiting to claim her betrayers.
