[Jade and Scarlet might not know, but you view the train upgrades on whether they would still be useful and relevant in the real world.]
[Needless to say, the Speed Path was pretty much useless since your speed in the real world was faster than the train could ever achieve.]
[As for the Attack Turret Path, you knew it would easily be power crept if you brought it into the real world.]
[After all, aside from the fact that you won’t be able to obtain train upgrade materials and turret module blueprints in the real world, you also become stronger in an instant due to the doomsday life simulation system.]
[If it were just to deal with small fries and fodders, the base turrets would be more than enough.]
[’It’s still better to treat the train as a movable base and shelter than anything else. Treating it as a war machine wouldn’t make sense since it’s overkill against weak enemies, yet too tasteless and not powerful enough to deal with stronger ones.’]
["From what the World Will mentioned, choosing a Train Upgrade Path will affect future upgrade paths."]
["In other words, as long as we stick to the Miniature Realm Path, its more advanced paths might allow us to create miniature worlds within each carriage."]
[After you concluded that, Jade and Scarlet didn’t disagree, and so, you all chose the Miniature Realm Path.]
[-Ding!]
{The Miniature Realm Path has been chosen!}
{The upgrades will be applied now.}
[After that system notification, you, Jade, and Scarlet noticed that the Apartment Unit’s size was expanding.]
[In just a few seconds, it suddenly expanded to ten times its previous size.]
[It wasn’t merely a direct increase in size. You noticed that the carriage modifier adapted to the increased size and even created four more guestrooms.]
[Not only that, it used the rest of the expanded size to improve the space of the master bedroom, which you and Jade used, as well as the living room, kitchen, storage room, and even added one more bathroom, which was near the five existing guestrooms.]
[Now, there was one bathroom that was beside the master bedroom and another one beside the guestrooms.]
[Needless to say, you and Jade decided to use the bathroom beside the master bedroom to be your and her exclusive use.]
[Scarlet was currently living in one of the guestrooms, and you had already given her daily supplies like soap, shampoo, and whatnot, which you had obtained from plundering the real world’s malls.]
[As for clothes, it wasn’t a problem since Scarlet could take out her own from her picnic basket.]
[Using the Train Conductor Authority to check the other carriages, Jade exclaimed, "Darling, even the ranch feels too vast now!"]
["Before, it felt quite small due to you taking a lot of livestock from the townspeople. Now, there’s too much area left."]
["With its vast size, if someone were born inside it, they would think it’s the real world. That’s just the Tier 1 of the carriage modifiers, and I’m quite excited to upgrade them to Tier 2 after it becomes an option after completing the Extreme Event."]
[If not for the restriction of being unable to upgrade modules until the first Extreme Event has been completed, you and Jade would have already chosen to upgrade the carriage modifiers.]
[Since that wasn’t an option yet, you and Jade chose to upgrade the train, spending a few hours to upgrade the train from Level 11 to Level 15.]
[By the time you were both done, it was already midnight.]
[Using the Train Conductor Authority, you checked the status screen of the train.]

[After checking the stats of the newly upgraded train, you realized, "I see. So that’s how the train speed and durability are increased."]
["I was quite surprised it was so low before, even after upgrading it to a higher level. But it seems only when Train Upgrade Paths and Modules are used to increase the speed and durability that it would become useful."]
["The reason why the train speed was so slow, and durability was so low, was because it shouldn’t be treated as such. But rather, treated as an improvement in base stats."]
["The correct way to make use of it is to gather Modules that can increase its multiplier so that the base stats would be put to good use."]
[Listening to your realization, Jade nodded in agreement.]
[Scarlet had already fallen asleep in her own bedroom that you and Jade allocated for her using the five guestrooms.]
[As for you and Jade, you had exhausted yourselves from upgrading the train. As the train level increased, the upgrade materials became rarer in quality and more difficult to exchange for.]
[However, it wasn’t for naught as the Miniature Realm Path Train currently has a speed of Mach 1.]
[Mach is a unit used to measure speed relative to the speed of sound in the surrounding medium, which is usually air. So Mach 1 is equal to the speed of sound, and Mach 2 would be twice the speed of sound.]
[In your past life’s world, the fastest train was only roughly about Mach 0.5, which was approximately half the speed of sound.]
[For Zenith to reach the speed of sound, you were already satisfied since it still has a bright future, considering it wasn’t truly that high of a level yet.]
[’Although to surpass the speed of light, a train ability that uses spatial folding to achieve it might be more feasible than by pure physical speed. But that’s assuming the world still operates on the laws of physics.’]
[Thinking about your current train speed, you were already satisfied and no longer dreamed of light speed, as it was too far from you.]
[The speed of light was approximately Mach 874,000, which was thousands of times faster than your fastest speed in the real world.]
[Moreover, that much speed was overkill as your current Mach 1 train speed should be more than enough to deal with monster waves and whatnot.]
[In fact, you possess a huge advantage over other Train Conductors and could even manually operate the train to ram the train against enemies or even against other Trains if you encounter them in Multiplayer-type stations.]
[With the Train Armor Plating and Advanced Energy Forcefield modules, you weren’t worried about your train not being durable enough.]
[After you and Jade upgraded the train, you took turns taking a shower and immediately headed to bed.]
[Although both of you had already confirmed your relationship, you and she weren’t in a hurry to hit home base since there was still much to do in the Train Survival World, so neither of you could become careless yet.]
[And so, four days have passed since recruiting Scarlet, and it was already the sixth day since Terrans were transmigrated to the Train Survival World.]
[During the past four days, you, Jade, and Scarlet didn’t encounter any notable stations, and some of them were even too safe or too weak.]
[Aside from opening Iron, Bronze, and Silver Chests to obtain more train upgrade materials, there were also no notable items that you and Jade obtained.]
[At most, you, Jade, and Scarlet had obtained some skill scrolls that suited each of you, and so they were used.]
[Furthermore, you haven’t even obtained any Carriage Modifiers or Modules yet, which made you realize that it was rarer than you expected them to be.]
[As for the previously obtained Train Carriage Modification Blueprint Voucher, you and Jade haven’t used it yet; you are currently in a "wait and see" mindset.]
[Although both of you were leaning to use it to exchange for a Blood Orchard and use one carriage and dedicate it to nurturing Blood Fruits.]
[However, you still held a luck mentality since if you were to gain an Orchard Carriage Modifier blueprint, then the voucher could instead be saved for more useful redemption.]
[While you were having that thought in mind, you and Jade soon heard a notification sound.]
[-Ding!]
{There’s only 3 minutes left before the mandatory station stop. Please prepare to disembark.}
[-Ding!]
{Station Pathways Ability activated!}
{The train is about to arrive at a station world. Please choose one from three of these stations.}
<{Station 1: Goblin Forest And Cave}>
{Description: A forest infested with goblin tribes. There seemed to be screams from breeding slaves coming from the goblin tribe’s cave.}
{Resources Available: Goblin Shaman Staff, Goblin Meat, Goblin Chief’s Necklace, Used Breeding Slaves (race ranges from humans, beastkin, and even a few elves), Magic Crystal, etc.}
{Danger Rating: Extremely Low}
