Train Survival: I Can Evolve Everything!

Chapter 39: Sublimation Again, Advancing to Level 4 Train

"Stay away!"

"Help! I was so close, just needed a little more to upgrade! Why won't anyone lend me materials?"

"Get lost! You damn monsters!"

"I don't want to die, I don't want to die!"

On this ordinary night, those train conductors who failed to reach Level 2 became food for the monsters.

Even among those who had upgraded, some unlucky souls still met tragic ends when their damaged trains slowed down and were overtaken.

————

Early next morning.

Gentle sunlight streamed into the train.

"Nice weather."

The Sunny Doll had predicted today's weather last night.

Mild and sunny.

The most comfortable weather for human survival.

Opening the window, letting the cool breeze from outside flow in, the wilderness beyond remained unchanged as ever.

"Seventy bullets spent last night? Fewer than I expected."

After checking the sentry's consumption from the night's survival period, Ye Qiyan noted that while the monsters couldn't catch his Level 3 train, some still managed to attack from the sides, damaging the train's flank.

He preferred avoiding damage since repairs would cost materials.

[Stamina: 100][Mental Energy: 120]

Pulling up the system screen, his personal stats showed both attributes fully restored.

Swallowing the last bite of White Forest Fruit, Ye Qiyan finished breakfast and rubbed his hands together eagerly.

"Wonder what train upgrade options I'll get this time."

Entering the locomotive, he placed his hand on the original control system interface.

Though unnecessary after binding with system modules, he enjoyed the ritualistic gesture.

"Sublimation."

[Stamina: 100→70][Mental Energy: 120→50]

[Train upgrade complete!]

[Current level: 4]

[Materials required for next upgrade: 500kg wood, 500 mechanical parts, 850kg metal, 40kg glass, 200 electronic components, 10kg gold, 15kg mithril, 1 calculation unit]

[Upgrade options unlocked]

[Congratulations! You are the first conductor in this sector to upgrade to Level 4]

[Title obtained: Upgrade Master]

[Congratulations on breaking the fastest Level 4 train record! Received 1 Conductor Enhancement Card]

The 100-point cost was only 10 points higher than the 90 required for Level 2 to 3 sublimation.

His Sublimation talent had significantly reduced the expenditure after self-enhancement. Without it, this upgrade might have completely drained him.

Breaking the record surprised Ye Qiyan somewhat.

After all, Shaya had given him a Flame Stone, meaning he could have reached Level 4 quickly even without sublimation.

If Shaya could provide such items, perhaps other veteran survivors could too?

Apparently, Ye Qiyan had guessed wrong.

Those who arrived in this world earlier didn't seem to interfere with newcomers easily—Shaya's case was exceptional.

Post-upgrade, he first checked the train's details.

The core components remained unchanged, with speed increasing by 20 km/h.

But the real changes lay elsewhere.

[Upgrade options unlocked]

[Level 4 train upgrade options:]

[1: Luxury Dream Bed (5 Train Coins)]

[2: Train Space Enhancement (8 Train Coins)]

[3: Train Module: Train Anywhere Door (6 Train Coins)]

[4: Smart Chip (10 Train Coins)]

"???"

Ye Qiyan's face filled with question marks after reading the options.

Five, eight, six, ten—buying everything would cost twenty-nine Train Coins?

Did the system tailor these options based on his current coin count?

With only thirty-nine coins total, purchasing these would leave him with just the ten from the Level 5 treasure chest.

"This is ridiculously expensive!"

Ye Qiyan winced at the cost, muttering complaints.

But Train Coins could be earned back, while upgrade opportunities might not return.

Still, he needed to evaluate each option before deciding.

Touching the hovering screen, he summoned detailed descriptions for all four upgrades.

[Luxury Dream Bed]

[Provides optimal rest on this bed, enhancing stamina/mental energy recovery speed. Guaranteed nightmare-free sleep]

Perfect! His current metal slab bed caused back pain, and the recovery benefits addressed his exact needs.

"Purchased."

[Train Space Enhancement]

[Expands all train compartments/locomotives by 1 meter in length, width, and height]

This immediately reminded Ye Qiyan of Shaya's church carriage—an obvious purchase.

"Bought."

[Train Module: Train Anywhere Door]

[Through compartment doors, freely access any train carriage]

"This seems incredibly useful too. Sold!"

[Smart Chip]

[Installs in mechanical constructs, granting basic artificial intelligence]

"If installed in WALL-E's head..."

"I'll... uh... wait on this one."

Ye Qiyan restrained his impulsive spending hand.

After buying the first three options, only twenty coins remained.

He hadn't forgotten yesterday's broadcast—today all platforms would be trading stations requiring Train Coins.

Spending everything now might leave him unable to purchase desired items later.

Better endure WALL-E's current state and save the coins.

Ye Qiyan decided to postpone the Smart Chip purchase.

Three stations' worth of time—even if he spent all coins at trading platforms, he felt confident about replenishing them.

Post-purchase, the train's expanded space felt noticeably roomier.

Placing the new bed in the temperature-controlled carriage now serving as his bedroom—without the space upgrade, this would have been uncomfortably cramped.

"Ahhh... haven't slept on something this comfortable in ages... no, never had anything this nice..."

Collapsing onto the bed, Ye Qiyan closed his eyes as the soft, resilient mattress enveloped him, dissolving tension and fatigue.

Checking his personal interface showed stamina and mental energy recovering at accelerated rates.

Indeed, making WALL-E wait had been the right call.
