The supermodel effect is none.

Chen Mang looked thoughtfully at the Level 5 supermodel effect. He now upgrades accessories by first upgrading them to Level 5, just in case this situation arises. If the Level 5 supermodel effect is none, then the Level 10 supermodel effect is certainly none as well.

However, this also solved a long-standing question in his mind.

He possesses the "Unlimited Upgrade" with a Level 0 privilege, allowing him to upgrade accessories continuously, such as "Armor" and "Pickaxe Production Line," elevating them to Level 5 or even Level 10.

But other train captains don't have such methods.

So what should other train captains do?

When the train is upgraded to Level 4, without Level 4 armor, how do they face Level 4 monsters? Without a Level 4 pickaxe, how do they mine higher-level resource mines?

Now it seems he already has the answer in his mind.

That is, when the train reaches Level 4, there should be higher-quality accessories to replace the low-quality ones currently within the train. Therefore, it seems quite normal for the "Crafting Table" accessory to have no supermodel effect at Level 5 since the sole effect of upgrading the Crafting Table is to enable the production of higher-level Energy Stones.

...

Chen Mang withdrew his gaze from the "Crafting Table" and looked at the two bullet production lines.

The "5.56mm Rifle Bullet Production Line" and the "12.7mm Heavy Machine Gun Bullet Production Line."

After consuming nearly 20,000 units of copper ore, he upgraded both accessories to Level 10.

Obtaining four supermodel effects respectively.

-

"5.56mm Rifle Bullet Production Line Level 5 Supermodel Effect": When producing bullets, the bullets can come with flames, having a miraculous effect on wood attribute monsters, with the price unchanged.

"5.56mm Rifle Bullet Production Line Level 10 Supermodel Effect": When producing bullets, the bullets can come with ice, having a miraculous effect on fire attribute monsters, with the price unchanged.

-

"12.7mm Heavy Machine Gun Bullet Production Line Level 5 Supermodel Effect": When producing bullets, they can produce split bullets, with the bullet splitting into three in mid-air while maintaining the same power, with the price unchanged.

"12.7mm Heavy Machine Gun Bullet Production Line Level 10 Supermodel Effect": When producing bullets, they can produce armor-piercing bullets, having a miraculous effect on heavily armored monsters, with the price unchanged.

-

"Phew..."

Sitting at the control panel, Chen Mang took a deep breath. These supermodel effects are naturally strong, allowing his firepower weapons to have more brutal damage while keeping the price unchanged.

Thus!

Inside the "Fixed Star" Train, all accessories have basically been upgraded, each possessing its own supermodel effect. Next, the train could start upgrading!

He looked at the conditions required to upgrade the train to Level 3.

"Upgrade Conditions": Must have 10 carriages, all six necessary vehicle accessories fully crafted, and consume 5,000 units of Level 2 iron ore. The total level of all accessories within the train must exceed 40.

All conditions were met and even exceeded.

Not willing to delay any further.

The next moment——

When 50,000 units of iron ore were missing from the train, a white light flashed from the control panel, and a semi-transparent panel appeared in front of him.

-

"Your train upgraded to Level 3."

"Unlock more buildable accessories and have more personalized and practical functions."

-

Chen Mang looked at the train panel with subtle anticipation in his eyes.

"Train Name": Fixed Star.

"Train Level": Level 3.

"Train Accessories": Level 10 Car Blades, Level 13 Spider Legs, Level 10 Car Sound System, Level 10...

"Number of Carriages": 10.

"Ore Units": 78,000 units of iron ore, 0 units of wood, 112,000 units of copper ore.

"Heritage Value": 0.

"Upgrade Conditions": Must have 18 carriages, all four necessary vehicle accessories fully crafted, and consume 10,000 units of Level 2 iron ore. The total level of all accessories within the train must exceed 80.

"ps": Before upgrading to Level 4 train, complete a transfer. The available directions are Mechanical Train and Flesh and Blood Train. Both transfer directions have their corresponding tasks. Completing them results in a successful transfer.

Finally... finally the Level 3 train.

There was no visible change to the exterior of the Fixed Star Train. Train upgrading does not enhance the train's combat power but only increases the basic speed of the train and allows more buildable accessories while unlocking more functions.

For instance.

The basic speed of a Level 2 train is 130 km/h. After upgrading to a Level 3 train, the basic speed reaches 160 km/h, which basically belongs to a marginal improvement.

In addition, nine more buildable accessories were added.

Among them, four vehicle accessories must be crafted. To reach a Level 4 train, these four accessories must be completed first. The remaining five buildable accessories are optional, of course...

For most people, so-called optional accessories are actually mandatory.

After all, if you don't craft these optional accessories, you cannot meet the total level requirement for train upgrades.

Unless you have other channels to obtain accessory blueprints.

Besides——

The most noticeable change is the addition of "Heritage Value" to the train panel. His heritage value is 0. With a sufficiently high heritage value, one can have the opportunity to trigger more events in an advanced area.

There are just a few sources to acquire heritage value.

For instance, accepting children under the age of 12 within the train or hosting a doomsday wedding with a "Doomsday Marriage Certificate" for survivors in the train.

The former demonstrates that, even in the apocalypse, there are people willing to consider humanity's legacy.

The latter proves that, despite the collapse of order in the doomsday world, true love still exists.
