However...

So far, he hasn't seen even one child, let alone anyone under 12. He hasn't even seen any fifteen or sixteen-year-olds. Pessimistically thinking, in the harsh environment of the apocalypse, it's likely very difficult for this group of people to survive a year after doomsday.

As for the Doomsday Marriage Certificate, he hasn't found a user for it yet.

But there's no rush for now; even if he got Heritage Value, it would only be effective in the advanced areas, and he doesn't plan to go there anytime soon.

And when he looked at the nine vehicle accessories that could be crafted, he finally understood how to repair the damaged train accessories.

-

"Mechanical Nanospiders": Yellow-grade accessory, requires 1000 units of iron ore to craft.

"Combat Training Virtual Space": Yellow-grade accessory, requires 1000 units of iron ore to craft.

"Built-in Space Stabilizer": Yellow-grade accessory, requires 1000 units of iron ore to craft.

"Single-Soldier Skeleton Armor Production Line": Yellow-grade accessory, requires 1000 units of iron ore to craft.

-

These four accessories are mandatory and essential for upgrading the train to Level 4.

"..."

Chen Mang's eyes flashed with an unusual light; all four craftable accessories are very strong!

The first, the Mechanical Nanospiders, are used to repair damaged accessories. Before having this accessory, all damaged accessories were irreparable and could only be used with makeshift adjustments, and if they were unusable, a new one had to be crafted.

It's a bit late appearing; the Level 3 train only has this accessory now.

But upon reflection, it makes sense.

After all, for most Level 1 and 2 trains, the accessories aren't very expensive. If they break, crafting a new one is fine. Unlike his situation, where each accessory's level is very high, replacing one when damaged would bankrupt him even if he had extra resources.

The second and fourth accessories.

Both are used to enhance the combat capabilities of individual soldiers.

The former improves combat literacy, and the latter is the Single Soldier Skeleton Armor, further enhancing the individual soldier's combat capabilities.

He looked at the description of the latter.

It's not about heavy armor, nor is it a mecha.

It's similar to a simplified steel skeleton attached to the human body surface, enhancing the overall physical fitness of individual soldiers in various ways but lacking any defensive capabilities, unable to withstand bullets or monsters.

Worn under clothing, nothing appears unusual from the outside.

However...

"..."

Chen Mang squinted slightly, actually, he always thought that enhancing individual soldier's combat capability was a pseudo-demand. After all, most of the time, the train handled all combat capabilities, but after upgrading to a Level 3 train.

Suddenly, there are two accessories that enhance individual combat capabilities.

And they're all in the craftable accessories.

As the saying goes.

First, there was Pangu, and then there was Heaven; only with Gouba do you get Bi.

If Pangu hadn't opened the heavens, and the latter hadn't created a hole, then these two would have no significance in existence.

This is a natural law.

Which means—

In the process of upgrading from a Level 3 to a Level 4 train, there's definitely a place that highly tests the individual combat capability of the train, and this testing place is likely a job transition task before upgrading to Level 4 or somewhere else.

Otherwise, the appearance of these two individual-enhancing accessories is entirely meaningless.

As for the last mandatory accessory to craft.

"Built-in Space Stabilizer."

This accessory, his slaves would probably like very much.

This accessory ensures that no matter how the train moves, whether it's climbing walls vertically, or floating like a leaf in the air, or even spiraling vertically upwards, it can keep the space inside the train horizontally stable.

No longer will his slaves in the slave carriage pile up like sardines when the train climbs walls.

"Pretty good."

These four accessories significantly enhance the train's capabilities. He looked at the other five non-mandatory craftable accessories.

...

-

"Central Air Conditioning": Yellow-grade accessory, requires 1000 units of iron ore to craft.

"Storage Box": Green-grade accessory, requires 500 units of wood to craft.

"Permanent Shock Absorption": Yellow-grade accessory, requires 1000 units of iron ore to craft.

"Medical Cabin": Yellow-grade accessory, requires 1000 units of iron ore to craft.

"Unknown Accessories": Unknown-grade accessory, requires 1 unit of iron ore to craft. Once the train completes its transition, it automatically becomes the heavy firepower external-mounted accessory for that transition path.

-

The effect of the first accessory is self-evident. Winter is coming, and with this accessory, the basic temperature inside the train can be maintained, preventing his slaves from freezing to death. It also has a fresh air effect, greatly improving the air quality inside the train.

The second accessory, the Storage Box, can store up to 1000 units of the same type of resource.

For example, 1000 units of iron ore.

It can be either Level 1 iron ore or Level 2 iron ore, freeing up a lot of space, though he still thinks the Level 10 refrigerator is a bit more useful.

The third accessory, "Permanent Shock Absorption", is a defensive accessory.

When the train's external defensive accessories, like "armor", are not damaged, it can effectively mitigate the impact from monster collisions.

The fourth accessory, the Medical Cabin, can heal most external injuries when lying inside. He has the Level 10 "Simple Medical Box" as a substitute, which is even more effective.

The fifth accessory...

This is the cheapest accessory he's ever seen, requiring only 1 unit of iron ore to craft, but it's temporarily uncraftable until the train completes its transition.

Transitioning to a "Mechanical Train" grants a heavy firepower external-mounted accessory of that series.

Transitioning to a "Flesh and Blood Train" has the same effect.

...

The nine craftable accessories mentioned above are the most noticeable changes after the Fixed Star train upgrades to Level 3.

It is worth mentioning that—

From 17 craftable accessories at Level 1, to 12 at Level 2, and then 9 at Level 3, the number of craftable accessories decreases with each train upgrade.

Many basic accessories, like "telescope" and the like, are missing.

And the remaining subtle changes are hidden within the control console and Train Panel, unlike the panel itself, which displays them intuitively; he needs to explore these himself.

For instance, a new feature in the Level 2 train's "Personalized Customization Carriage" was added.

The carriage originally equipped with the "40-tube Sakura Fall Rocket Cannon" was an open-air carriage, surrounded on all sides and exposed on top. The drawback is that accessories are extremely prone to damage, given the lack of protective external armor.

After upgrading to Level 3, a more advanced open-air carriage can be crafted.

The open-air carriage transforms into a fully enclosed type, with the rocket cannon hidden inside the carriage. When needed, the armor on top retracts into the carriage, and the lift platform raises the firepower apparatus inside the carriage, roaring and shooting into the flames.

An extremely practical feature.

The price isn't expensive; upgrading one section of the open-air carriage to the advanced version only costs 1000 units of iron ore. He has two carriages, so upgrading them all only costs 2000 units of iron ore in total.

The "armor" that appeared on top of the open-air carriage doesn't require additional iron ore to supplement.

It was already consumed during the previous armor upgrade.

In addition—

The train control console now has three extra buttons, namely:

"Family Planning."

"Instant Self-Destruction."

"Instant Ejection."

Pressing the first button releases a spray inside the carriage, preventing all members, except for creatures in the "Breeding Carriage," from getting pregnant.

He immediately pressed this button.

So far, he doesn't want anyone inside the train to get pregnant.

The second button is also quite crude; pressing it causes the train to self-destruct instantly, unleashing immense power.

"..."

Chen Mang glanced at this button, his mouth twitching slightly. If he accidentally hits this button one day, it would be an instant ascent. But in the next moment, a transparent plastic cover emerged around the button, enclosing it within.

This plastic cover features fingerprint recognition.

Only he can open this plastic cover. If anyone tries to forcibly open it, under the operation of "Train Assistance AI," the "Built-in Fire Control System" will instantly lock onto the enemy and open fire at once.

And even if the button is pressed again, one must also click confirm on the control console screen for the self-destruction sequence to begin.

This pretty much ensures safety.

After all...

No one can accidentally open the plastic cover, and mistakenly press this button, while also accidentally happening to hit confirm on the screen.

If someone is this careless...

Then it's perfectly normal for King Yama to accidentally twitch and erase your name on the Book of Life and Death.
