Meteorites fell from the sky, blocking the sun. In a land of ice and snow, there were scattered shelters. Lu Chen held a nano core in his hand. He started by learning knowledge by himself, and used the nano core to realize his ideas step by step, develop technology, and strive to survive. Can he finally walk into the starry sky?

The story begins three days before the meteorite fell

PS: The beginning of the disaster article is similar, but the content is different

All of humanity has entered a game called Train Survival. The tracks are endless and no one knows where they lead to.

There are also various carriages on the tracks, including supply carriages, trap carriages, weapons... and possibly... scary and terrifying things.

Zhou Yun discovered that his rate of return golden finger could still be used.

【Return rate】: 4900%~positive infinity.

Risk: Low

[Suggestion]: Low risk, super high return, highly recommended. As a businessman, 300% profit is enough to make you abandon your morals, 5000%, even if it means selling your soul, you must choose it!

Chen Mang traveled to a doomsday world, where corpse tides could be seen everywhere, and death was everywhere.

Survivors need to become train conductors, and gradually upgrade and strengthen their own trains by collecting minerals and other resources, so as to control the train to survive the tide of corpses.

Or become a slave to other train conductors and live under someone else's roof.

All trains have a level limit, and the effect will become stronger every time they upgrade.

However, his natural birthmark gives him the ability to upgrade vehicle accessories without limit.

When several white vehicle accessories such as "car blades" and "drills" that were looked down upon by other train commanders were raised to hundreds of levels.

Only then did I realize that I was already invincible in the world.

So far—

A giant train with hundreds of cars armed to teeth began to roar in the wilderness of the doomsday.

…

"There are only two kinds of people in this world."

"Train conductor or slave."
