[Hearing Jade’s opinion, you nodded, "That’s true, we don’t need those train upgrade paths as they don’t fit our envisioned development path for Zenith."]
["As for the Mobile Fortress Path, it’s not that bad. If the Pocket Dimension Path didn’t exist as a choice, I might have chosen this. Unfortunately, it’s still not as good as the Pocket Dimension Path."]
["The Pocket Dimension Path is tailor-made for us. It’s like the true upgrade path above the Miniature Realm Path. On the other hand, the other three train upgrade paths are just derivatives of the Miniature Realm Path."]
["Not to mention, the Mobile Fortress Path has the flaw of being powerful when it’s invaded and the enemies enter the train."]
[Jade also realized the flaws of the Mobile Fortress Path, "If the enemies enter our train, it’s really risky. Even if we can treat each carriage as dungeons and lay traps and turrets inside, those are still unnecessary risks."]
["The perks of a 70% damage reduction might be nice, but the risk is still unnecessary since we already have the Passenger Safety Mechanism in terms of life-saving means."]
["No point in letting them inside and risking it when we can just avoid having enemies even intrude on the train or destroy it. We aren’t relying on turrets anyway, but our own combat power."]
[Jade hadn’t forgotten that you weren’t keen on focusing on turrets. Not to the point of neglecting it, but it wasn’t at the top of your priority list when compared to focusing your effort and time on resources that could improve your train crew’s combat power.]
[She knew that you weren’t counting on turrets and other external means to deal with the strongest enemies. At most, there’d be enough turrets to deal with fodders like those Terran Train Conductors.]
[While you and Jade came to an agreement on choosing the Dimension Pocket Path as your second train upgrade path, you didn’t immediately choose it yet, but instead, asked for Scarlet and Old MacDonald’s opinion in the zenith chat group.]
{Scarlet: I’d choose the Pocket Dimension Path. With it, we can assign the empty spaces of those unused carriages to carriages that have already been modified. We still have around six unused carriages, and the Realm Core can allow us to reassign the spaces for those to other carriages, such as the Blood Orchard, for example.}
{Scarlet: Moreover, the Realm Core allows us to create subspaces and even have limited control over the flow of time within that space. The existence of Realm Energy also allows us to no longer rely on having numerous carriages; instead, it enables us to focus on expanding our train’s interior size.}
{Old MacDonald: Young lad, I also support choosing the Pocket Dimension Path. It might not be an issue now, but later on, when we have a variety of plants and even magical beasts... separating them with the subspace is a must.}
{Old MacDonald: As good as my beast-taming skills are, some prey animals just can’t live in peace in the same land as their predators. There are also crops and plants that can’t coexist in the same habitat, so having subspaces will benefit us in the long run.}
{Zayne: I see... Then, since it’s an unanimous decision of Zenith, Jade and I will choose the Pocket Dimension Path. Don’t be startled by the sudden changes of the train as it will undergo an upgrade.}
[After obtaining their opinions in the chat group, you nodded at Jade and immediately used your Train Conductor Authority to choose Pocket Dimension Path.]
[Your choice was supported by Jade, so there wasn’t any issue in the choosing process.]
[-Ding!]
{The Pocket Dimension Path has been chosen!}
{The upgrades will be applied now.}
[After that system notification, you and Jade noticed that the size of the train’s interior had increased by approximately 20 times.]
[However, that wasn’t all, as you noticed that in the locomotive, there seemed to be an illusory core hidden in another dimension. At least, it was in the same location as the train’s engine, yet wasn’t in the physical dimension but on another one.]
[’Is that the Realm Core? Using my Train Conductor Authority, I feel like I can freely expand the space in my train and no longer be limited to the default interior size.’]
[’Moreover, the carriages now mostly exist as spatial anchors to stabilize any subspaces placed around them. However, due to the existence of the Realm Core, their spaces can be merged or even be connected seamlessly as if they were one big carriage rather than ten.’]
[Not only that, but you also felt that there was an energy flowing within the Realm Core, but it wasn’t that much, only enough to maintain the operations of the train.]
[You figured it was the so-called Realm Energy. And according to your Train Conductor Authority’s feedback, anything could be fed to the Realm Core, and it would be converted to Realm Energy.]
[It was mostly used to recycle useless items and wastes into usable Realm Energy. Moreover, Realm Energy could even be used as the train’s fuel. Train fuel could also be used to convert a meager amount of Realm Energy.]
[Unless it was for emergencies, you wouldn’t convert train fuel to realm energy, as there wasn’t that much yield when converting the two. However, in some ways, the Realm Core could at least be used as a back-up fuel tank for the train as long as it wasn’t depleted of realm energy.]
[’The Realm Core seems to prefer space-attributed items. Although anything can be converted into realm energy, the amount of realm energy yielded would still depend on the item’s quality, quantity, and whether it was space-attributed or not.’]
[’Also, with the Realm Core, I also feel that I possess the ability to create subspaces and control the flow of time within the carriages. However, the time flow control is mostly limited, and at most, it’s useful for making training grounds where the flow of time inside is faster.’]
[’I don’t know about other time chambers, but this one particularly truly achieves time acceleration. So, with a time flow ratio of 2:1, spending 2 days inside while only a day passes outside, my body inside will definitely age 2 times faster, aging 2 days rather than just 1 day.’]
