[Double Survival] [Single Female Lead Pure Love] [Both Leads Are Mischievous] [No Mary Sue] [Game Data System] [Disaster] [No System] [Early Stage Stairs + Mid-Late Few Use Elevator, Others Use Stairs]

Hundreds of billions of people worldwide are paired up to traverse an infinite building to survive, and all survivors need to climb stairs.

Each time they climb the stairs, there is a chance to find resources on the floor or in the corridors.

But dangers may also appear... or they might encounter other players while climbing.

Moreover, at intervals, various disasters break out between the buildings.

Gu Fan and his childhood friend, the school belle of Yangcheng University, Su Liyue, are matched together. The two share a close bond, supporting each other back-to-back, overcoming hardships, climbing floor after floor, fighting to survive together...

[Farming + Lord + Witch + Cutting-Edge Technology]

Transmigrated into the body of a useless, exiled lord, he starts out in an extremely cold wasteland, with no money, no food, no system, and has to face a "calamity witch" who is about to go berserk?

The crowd cried out in terror, "Burn her! She'll destroy the world!"

Victor, seeing the fire elementals surging wildly around the girl, was overjoyed: "Stop! This isn't a calamity; it's clearly a self-propelled humanoid nuclear reactor!"

[Fire Witch]? That's the core of blast furnace steelmaking, that's a 24-hour constant temperature boiler!

[Earth Witch]? That's a humanoid tunnel boring machine, a 3D printer for skyscrapers.

[Lightning Witch]? That's a radio electromagnetic tower, a humanoid battery for a railgun!

When the Holy See's knights arrived with torches, intending to judge the heretics, they were met with a mechanical city forged from steel rising from the ground.

Victor stood atop the steam-shrouded city wall, behind him a row of witches with fanatical eyes:

"Heretical? No, no, no, Your Excellency, allow me to introduce this as my First Industrial Production Brigade."

One day, the Pope arrived: "Victor, you harbor heretics, what is your punishment?"

Victor pointed to the hundreds of intercontinental ballistic missiles poised for launch behind him and smiled:

"My lord, times have changed."
