3005 Book(s) Related to my roomate isn't from this world

We’ve been married for five years. Then, she got pregnant with someone else's child.
In front of everyone, she said: "Ethan doesn't want this baby. You've always wanted one, right? Fine, take it and raise it."
In that moment, I finally understood: she wasn’t incapable of loving someone—she simply never saw me as a human being.
I took off my wedding ring, left it on the tray, and bought a one-way ticket to the North. My family said I wouldn't survive in the frozen North; she said that without her, I was nothing.
Three years later, she tracked me down using the GPS hidden inside that ring. She pushed open the door to my attic room, finding only a note I’d left: "Don't look for me. We're square."

In my past life, I personally dug up two alien meteorites, handing the blue one that granted "Frost Mastery" to my childhood friend, Mike. He repaid me by sealing me inside an ice wall, cursing me to "die like a piece of trash" in the minus 70-degree blizzard.
When I opened my eyes again, I was back at the initial blast site.
This time, I didn't even spare him a glance; I stuffed both meteorites into my pocket.
I transformed a missile silo into a doomsday bunker, brought my parents inside, and stockpiled ten years' worth of supplies.
When Mike arrived with a gang of thugs to smash my door down, I stood in the warm command center, watching half his face rot with frostbite on the monitor.
I didn't open the door.
This time, I am sending back the despair of my past life tenfold.

I am a mermaid.

To walk toward him, I swallowed a dark potion, shedding my tail for a pair of legs.
Every step felt like treading on sharp blades, yet I endured it all willingly.
He took me in, promising to protect me for the rest of my life.

Then, his ex-lover returned.

She orchestrated one accident after another to frame me—a slashed costume, a staged fall down the stairs... And every single time, convenient "eyewitnesses" immediately pointed their fingers at me.

He believed them all.

Until a falling stage light crushed her legs.
He pinned me to the operating table, personally severed my legs, and transplanted them onto that woman.

What he didn't know was that anyone who walked on these legs would have to suffer the excruciating agony of stepping on knives.
He simply told me coldly: "You ruined her ability to dance, so you will pay with your legs."

That night, alone and broken, I wheeled myself to the beach.
Using only my bare hands, I crawled across the coarse sand, into the crashing waves, and returned to my true home.

——Leaving him to stare at the security monitors, watching helplessly as I sank into the dark sea, never to surface again.

In my last life, a friend I’d trusted for ten years drove a knife into my heart over a single biscuit. When I opened my eyes again, we had both been reborn—right before the extreme freeze arrived.

He was convinced the apocalypse had come. He borrowed from loan sharks, rented a massive warehouse to hoard supplies, and even crowned himself king during the icebound period, killing without mercy.

But he didn’t know the truth:

This disaster would end completely after only thirty days.

While he taunted me like a madman, I didn’t expose him. I calmly requested thirty days of paid leave from my company.

This time, I’ll sit in a warm, climate-controlled room and watch—when the state machine restarts on day thirty—how he drops to his knees and sobs in despair.

After I retired, I was willing to do the dirtiest work at a small auto repair shop—just to give my sick daughter an ordinary childhood.
I endured my mother’s insults, my eldest brother’s wage cuts, my younger brother’s extortion.
But they actually joined forces to steal my daughter’s life-saving money for gambling, then sold me into an illegal mine to pay off their debts.
When the iron chain locked around my wrist, when my daughter cried in despair, the killing intent that had slept in my blood for three years finally woke up completely.
They had no idea I was once the iron-blooded God of War—commander of a million troops, the name that made enemy nations tremble.
