Global Cataclysm: I Built a Wandering Train

[Apocalyptic Old World + Rebirth + Superpowers + Darkening and Revenge, No Saintly Heroine]

Catastrophe engulfs the globe. A superstorm half the size of a country rages across the land, and temperatures in its eye drop by ten degrees every second, freezing people into ice statues in an instant.

The earth splits open, and countless Xina vines spread from beneath the ground. An unknown ecosystem descends, giving rise to Source-Devouring Beasts that feed on the life essence of humans. Ninety percent of humanity dies.

In his previous life, Qi Feng was killed by his girlfriend and neighbors because he had a heart of gold.

Reborn one month before the great catastrophe, he awakens a fusion superpower that lets him reshape and fuse any inorganic material.

So he finds a heavy-duty train weighing 300 tons and reshapes and fuses it into a wandering train.

Short on supplies? As long as he has the materials and blueprints, he can fuse together anything he wants, without limit.

Need weapons and equipment? Just look at the 30 mm Gatling guns on either side of my train cars and the 120 mm main cannon on the locomotive!

Uncomfortable living conditions? The wandering train he built isn't just a super mobile fortress. It has everything anyone could need.

When the apocalypse arrives, others either freeze like dogs or have their life essence devoured by Source-Devouring Beasts. They'll do anything for a bite to eat, while Qi Feng lives even more comfortably than he did before the apocalypse. Everything on the train is his, and everyone aboard has to obey him.

Ex-girlfriend: Qi Feng, just let me onto your train. I'll do anything you ask.

Arrogant rich kid: Brother Qi, I'll give you everything I have, just give me one meal.

Qi Feng: Sorry, I've already got enough mutts at home.
