Yang Feng somehow transmigrated into a different world and received a legacy of an ‘ancient high tech’ family, which does not directly raise his power, but gives him the technology to build things which are way more advanced than the seemingly medieval world.

But to build something you need resources and energy. To receive resources you need strength. To gain strength you need knowledge. To gain knowledge you… need strength? or a background? Or maybe a fully armed army of high tech robots who aren’t afraid of death?

But is this legacy really for him to keep?

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."
