Classroom Survival: Am I the Only Man in the Entire Train?

In an instant, every subway train in the world hurtles off its tracks and plunges into the endless darkness below!

[Welcome to the world beneath the earth. Drive your train and do your best to survive!]

Surface civilization is utterly destroyed. Ancient underground monsters awaken, and every subway station becomes a death zone.

Just as intern Zhou Yang despairs, he discovers that he has gained full control of this “Nursing College Express”!

While other survivors huddle trembling in battered train cars, killing one another over a bottle of dirty water,

Zhou Yang has already activated the [Train Car Upgrade] System!

[Use 10 “Iron Ingots” to convert Car 2 into a “Basic Greenhouse”!]

[Use 5 “Monster Cores” to install an “Electromagnetic Defense Net” in Car 3!]

[Use 1 “Rare Blueprint” to unlock the S-rank car “Mobile Operating Room”!]

Outside the train are man-eating monsters and the darkness of human nature.

Inside, Zhou Yang and dozens of gentle, lovely nurses gather around an electric hot plate to eat hot pot.

“Brother Zhou Yang, today’s vegetable salad is really delicious~”

“Zhou Yang, I just made a stamina-restoring potion. Hurry and drink it, okay?”

“Stationmaster, do you… do you still need personal nursing care?”
