The Yellow Springs Road, eight hundred li long, connects the Ghost Gate and the Bridge of Helplessness.

  The road surface was potholed, flanked by muddy swamps, and countless ghostly hands reached out from underground trying to grab passersby's ankles.

  At this moment, Slayer was on this road... racing.

  It was unknown which dimensional pocket he pulled it out from, but he was currently driving a heavy armored off-road vehicle (WARTHOG style). The engine roar made the Equinox flowers tremble.

  This car had no suspension system, or rather, it didn't need one. Because when encountering large rocks or blocking demons, Slayer just floored the gas and smashed through/ran over them.

  Clang! Boom!

  He cleared the way in front, forcibly pressing out a wide, but still very uneven dirt road on the muddy Yellow Springs Road.

  Singularity sat in the passenger seat, bumped so hard his breakfast (though he hadn't eaten) was about to come up.

  "Big Hero! Slow down! Slow down! My glasses are going to fly off!" Singularity screamed, clutching the handle. "This road condition is terrible! Can your suspension take it?"

  Slayer jerked the steering wheel, drifting and tail-whipping a zombie that tried to climb onto the car into the air.

  He patted the steering wheel, meaning: Car's fine, road sucks.

  Indeed, the road sucked.

  Even though Slayer cleared the obstacles, this muddy road was still torture for the thousands of ghosts queuing behind to reincarnate.

  Singularity fought back his motion sickness, watching the passing scenery (and the ghosts being knocked flying).

  The "Infrastructure Radar" in his brain began to alarm.

  "No good. With this transport efficiency, we can only move fifty thousand ghosts a day. And the current death rate... it's simply not enough."

  Singularity suddenly had a flash of inspiration.

  He looked at the two deep tire tracks under Slayer's wheels.

  "Isn't this a ready-made... Roadbed?"

  If you spot this story on Amazon, know that it has been stolen. Report the violation.

  Slayer was responsible for leveling the land (physical rolling), so he just needed to...

  "Stop! Big Hero, stop the car!"

  Slayer slammed on the brakes, and the car slid for fifty meters on the mud before stopping.

  Singularity jumped out of the car. Although his legs were a bit jelly, his eyes were incredibly determined.

  He took out his tablet and pulled up the latest [Yellow Springs Road Rail Transit Plan].

  "We're not building a road." Singularity pointed to the straight path ahead. "We're building Maglev!"

  He pulled handfuls of metallic glowing "Gravity Rune Spikes" from his sleeves.

  "Slayer, Big Hero, I need a favor."

  Singularity handed a box of rune spikes to Slayer and pointed to a launcher device at the rear of the car.

  "You keep driving, just charge forward. These spikes will automatically drive into the ground."

  Slayer looked at the box of spikes, then at the long wilderness ahead. He seemed to understand that this was a new "gameplay mechanic."

  He nodded and restarted the engine.

  Vroom—!

  The off-road vehicle roared again.

  But this time, accompanied by the rhythmic thud-thud-thud sound from the rear, rune spikes were accurately driven into the ground.

  With every spike driven in, a blue magnetic line lit up on the ground.

  Singularity stood at the starting point, forming hand seals, chanting:

  "Earth veins as rails, magnetic levitation. Rise!"

  Hum—!

  The rune spikes driven underground resonated instantly. Countless metal elements were sucked up from underground, automatically condensing, stretching, and shaping in the air.

  In just ten minutes.

  A two-way metal track, glowing with faint blue light and suspended three feet above the ground, stretched like a silver dragon along the path opened by Slayer, all the way to the end of the line of sight.

  This was no ordinary rail. This was a "Superconducting Maglev Track" driven by the earth's magnetic field and spiritual power.

  Immediately after, Singularity downloaded a model from the "Heavenly Dao Cloud."

  [Vehicle Model: Harmony · Nether Express.]

  [Capacity: 1000 passengers/car.]

  [Speed: 600 km/h.]

  Several streamlined trains made of a mix of white bone and black iron appeared out of thin air on the tracks.

  "Done!" Singularity wiped his sweat.

  At this time, the first batch of trial-run ghosts were herded onto the train by Yin Soldiers.

  "Attention passengers, this train is bound for the Bridge of Helplessness. Please fasten your seatbelts and do not extend heads or hands out of the window (or demons will bite them off)."

  Whoosh—!

  The train started. No vibration, no noise (except wind noise).

  The Yellow Springs Road that originally took three days and three nights to walk... now took ten minutes direct.

  Slayer stopped the car and looked back at the train whizzing by.

  He didn't feel upstaged. On the contrary, he thought this was very reasonable.

  Efficiency. That was what he cared about.

  Singularity teleported (borrowing the Underworld teleportation array) to Slayer's side, proudly pointing at the silver dragon:

  "Reincarnation this way, express train. How is it, Big Hero? This is much smoother than your off-road vehicle, right?"

  Slayer didn't speak, just silently put the off-road vehicle away.

  The way he looked at Singularity changed. This wasn't just a Daoist who picked up trash; this was practically a humanoid mobile engineering team.

  "Walking vs Transportation."

  The logistics system of the Underworld was thoroughly opened up.

  "Next chapter, time to find some entertainment for these bored ghosts on the train—for example, let them see their families back home?" Singularity looked at the blueprint for the "Home-Viewing Terrace (Wang Xiang Tai)" modification in his hand and smiled with humanistic care.
