Train Survival: You're really trying to survive!

After Song Mingyu returned from her studies, Su Li returned the skills that Zheng Hongyuan had left behind to him.

With this, the team's strength had once again increased to a higher level. Facing the challenges ahead, Su Li was even more confident.

With five days of rest remaining, Zurich naturally wanted to strengthen his train.

Zuli first bought the level 5 train blueprint, spending 300 survival coins.

[Level 5 Train Upgrade Plugin]

[Consumables: 500 Wood, 500 Stone, 300 Iron Ingots, 300 Copper Ingots, 300 Silver Ingots, 100 Gold Ingots, 50 Lower-Grade Magic Energy Crystals, 10 Monster Cores, 5 Fire Elemental Shards, 10 Earth Elemental Shards, 5 Wood Elemental Shards]

Su Li glanced at the level 6 blueprint again. The blueprint cost 500 survival coins. From level 6 onwards, the train would no longer need to burn wood, but instead would need fuel oil. Upgrading to level 6 required a large amount of resources, not to mention a [High-Performance Internal Combustion Engine].

[High-performance internal combustion engine] No blueprints are required; you only need to create a basic workbench to build it.

However, the tricky part is that manufacturing internal combustion engines requires new metals, titanium ingots and platinum ingots.

These two metals are partially distributed in Level 1 worlds, and widely distributed in Levels 1-2. In other words, under normal circumstances, ordinary players will only begin to encounter these resources after reaching the peak of the Iron level or the Silver level.

There are some resources available from opening treasure chests, but the quantity of metal ingots is limited, and the drop rate for these two metals is very low, making them extremely expensive. It's not worthwhile, so after careful consideration, Su Li decided to abandon further upgrades to the locomotive and instead upgrade the carriages.

[Superior Class Carriage: Requires Train Level 4 or higher] 300 Survival Coins.

[Consumables: 300 Wood, 300 Stone, 100 Iron Ingots, 100 Copper Ingots, 100 Silver Ingots, 10 Wood Element Fragments, 5 Water and Fire Element Fragments, 50 Gold Ingots]

Su Li looked at her supplies and realized that she only had 200 silver ingots that she had obtained from the newly established Blue Star government, which was Zheng Hongyuan.

It's perfectly fine to use it to upgrade the premium class carriages.

Zurich will build the upgrade module for the carriage.

The train automatically drove into the factory area. Because there were many people in the area, Su Li even had to wait in line for a while. This made Su Li miss the happy life she used to have all the transfer stations to herself.

After wasting a whole day, Su Li finally upgraded his carriage.

After the upgrade, it's natural to take a good look at the changes in the carriages.

The high-quality carriages, equipped with a level 4 locomotive, naturally have a different width, upgraded to 4 meters.

The length remains unchanged at 25 meters.

Su Li entered the carriage and opened the control panel, discovering that this high-quality carriage was equipped with electrical wiring. Furthermore, the interior's insulation and food preservation capabilities had been further enhanced.

Then the strength of the carriages was improved.

Su Li pinched her chin, her expression not good: "I don't feel there's anything special about it, it's a bit of a loss."

"However, without upgrading to the Excellent level, you cannot upgrade to the next level. Moreover, many facilities can only be built at the Excellent level."

"Next, let's see what the God of Rangers has given us."

Su Li took out a piece of square steel and a box of screws.

Galvanized square steel

My second aunt's expansion screws

Combining these two methods allows for increased interior space within the train carriage.

This was the first time Song Mingyu had seen this thing, and she couldn't help but complain, "Are you going to completely remodel a coffin room too?"

Su Li was surprised. "You watch these kinds of videos too?"

"Working the night shift in the emergency room is incredibly busy, but also incredibly boring," Song Mingyu explained. "When there's nothing to do, I watch these short videos."

Sofia and Ivan wouldn't get the joke, because when the apocalypse came, these videos of modified coffin rooms hadn't yet spread outside of China.

"It all depends on whether this prop works or not. If it doesn't, we'll have to build a new carriage."

The thought of the materials required to upgrade a carriage from top to premium level gave Su Li a headache.

But they had no choice but to upgrade. If they didn't, many functional rooms wouldn't be able to be set up. Su Li knew that some teams didn't even have dormitories; everyone slept on the floor, leaving all the space for functional rooms.

Su Li took out galvanized steel bars and expansion bolts and selected which ones to use for the new carriage.

Suddenly, rhythmic music filled the quiet carriage. Su Li was first surprised, then her expression turned into that of an elderly person using a cell phone on the subway.

[BGM: YOUBRINGMEJOY]

As soon as the decorating tune begins, the narration follows closely behind.

[A modified train houses a 100-square-meter coffin room]

"A 100-square-meter room for a coffin? That's bigger than my house. Is this corpse even human?" Su Li couldn't help but complain.

Then a poorly modeled humanoid character wearing brightly colored floral shorts suddenly popped out and started waving its arms and legs in front of Su Li and the others.

[Dazhuang spent days scavenging in the game "Eternal," finally gathering enough materials to buy a house with great excitement. But upon closer inspection, his spirits plummeted—the house was so small no one wanted it. Dazhuang exclaimed that he'd completely ruined the game.]

"Is the God of Wandering Knights really that abstract?" Song Mingyu couldn't help but complain again.

The Russian girl and boy duo were completely stunned.

[1. By breaking open the floor, the entire carriage sinks 2 meters, providing a more open view.]

With a deafening crash, the entire floor of the car in front of Su Li shattered, and Su Li and the others plummeted two meters downwards. Su Li's mind went blank for a moment. "My brand new car!!!"

[2. Break open the ceiling and raise the entire carriage by 2 meters to allow better sunlight into the carriage, so that Dazhuang can sunbathe inside.]

With another loud bang, the ceiling flew off.

[3. Dazhuang is very strong, and it's very difficult for him to walk through the half-meter-wide aisle. Open the left side of the carriage so that Dazhuang can dance freely in the aisle.]

Su Li was numb. This brand-new car she'd just picked up—now the floor was gone, the ceiling was gone, and even the left side of the carriage was gone. All that was left was a pair of floral-patterned shorts waving their hands inside the carriage!

When Zu Li stands here, there are no walls on three sides and only one wall, making her look like a character illustration from a mobile game.

[4. Take out the galvanized square steel you just bought, and then borrow some expansion bolts from your second aunt.]

A galvanized square steel frame was used, with several crossbars welded together for added sturdiness. My aunt's expansion bolts were used to firmly secure it. Solid wood flooring was then laid on top.

Large quantities of galvanized square steel billets flew through the air, forming a new frame. Then wooden planks were laid down, and in a dazzling display, the carriages were reassembled.

The background music stopped at this moment, and Su Li closed her wide-open mouth.

Before him was a brand new train carriage.

The renovation is complete and the space in your vehicle has been expanded.

As your carriage continues to be upgraded, the expanded second-floor space will also be updated to match the original size.

However, the expansion of the carriage space caused by using props will not be synchronized with the expansion of the second-floor space.

[Example: When a player upgrades their carriage, the main body width increases to 5 meters. This is considered a main body expansion, and the second floor is also expanded to 5 meters.]

Players can use items to expand the interior space to 10 meters wide; this is considered a space extension. The second-floor space will still maintain the original 5-meter width of the carriage, requiring the use of items to expand the second-floor space.

Once Su Li understood the rule, she couldn't wait to run outside and check the exterior of the carriage.

The exterior of the carriage remains unchanged; it is still a 4-meter by 25-meter train.

Su Li returned to the carriage and began inspecting the new carriage.

The length of the carriage has been extended to 27 meters. It still has a functional room every 5 meters, with the extra 2 meters for passageways and a small staircase leading upstairs.

宽度拓展到了5米，多出来一个1米的通道。原本的功能房的宽度从3.5米变成了4米，高度还是3米多。

Su Li walked up the stairs to the second floor. The second floor was also 5 meters by 27 meters. It was a spacious area, waiting for Su Li to be assigned a room.

Su Li went downstairs and summarized the changes. "We added two more floors of space and optimized the passageways, expanding out the passageways that originally occupied space."

Furthermore, the extra layer of space is still a premium-grade carriage.
