System: My Doomsday Train-Chapter 577 - 291: Gray-grade components.

After the Constant Star Train was upgraded to Level 19, besides this new function, two additional accessories could be crafted.

-

"Wheel Changer": Red-grade accessory, requires 50,000 units of iron ore to craft. 𝘧𝘳𝘦ℯ𝓌𝘦𝒷𝘯𝑜𝑣𝘦𝓁.𝒸𝘰𝓂

"Trait Material Research Line": Gray-grade accessory, requires 100,000 units of iron ore to craft. This accessory is a special accessory and cannot be upgraded.

-

Only these two accessories.

The first accessory was already very familiar. He had obtained this red-grade accessory with a Rare Train Order, and it was very useful, allowing seamless wheel changes. But the second accessory...

"..."

Chen Mang frowned slightly as he looked at this accessory panel.

The effect is—

It can manufacture "special" materials, provided there is a sample of the material, and it can consume iron ore to create this material.

For example...

If a material is "titanium steel," it is certainly impossible to create such a material with the current train’s capabilities. But if this material is placed as a sample in the "Trait Material Research Line," this material can be mass-produced by consuming iron ore.

"This..."

He was stunned in place, and the scenario for using this accessory almost instantly flashed through his mind.

Currently, the "Cosmic Receiver" has 10 "Receiving Devices," with a daily mining capacity of 4.8 million units of iron ore. The main limitation on manufacturing "Receiving Devices" is materials, but if these special materials can be mass-produced...

This means that "Receiving Devices" can be mass-produced.

receiving devices, with a daily mining capacity of 4.8 million units of iron ore.

Then... what about 100? 1000? Or even tens of thousands?

This accessory might not have a significant impact on other trains, but for him, it’s a killing blow!

And it’s also the first gray accessory he’s encountered.

Cannot be upgraded?

"..."

Somewhat disbelieving, Chen Mang activated Level 0 permissions, planning to force an upgrade. In the next moment—

-

"You consumed 2.7 million units of iron ore to upgrade the ’Trait Material Research Line’ to Level 10."

"And gained two Supermodel Effects."

"Trait Material Research Line Level 5 Supermodel Effect": Material consumption for manufacturing special materials is halved.

"Trait Material Research Line Level 10 Supermodel Effect": Material consumption for manufacturing special materials is halved.

-

Two consecutive half-consumption Supermodel Effects.

This can’t be upgraded?!

Who said it can’t be upgraded?

The resources consumed to craft and upgrade are basically the same as those required for upgrading red-grade accessories.

"Ai."

"Is there information on gray-grade in the database?"

"Yes."

In the train cabin, Ai’s voice sounded: "Gray-grade accessories are special accessories and are not categorized from white to seven-color grade."

"All accessories are engineered by scientists from the Mechanical Civilization, encapsulating a manufactured weapon within an ’Accessory Blueprint’ for mass and rapid production."

"For example—"

"If you manufacture a lithography machine, it requires many resources and is difficult to mass-produce, but you can encapsulate it within an ’Accessory Blueprint,’ allowing others to make one without understanding the technology, just by paying certain resources."

"Different accessories require different resources based on their strength."

"Supermodel Effects are theoretically random and completely unpredictable."

"The scientific term is ’Cosmic Empowerment.’

"It’s essentially ’completely random and uncontrollable.’

"When an accessory blueprint is manufactured, nobody knows what the Supermodel Effect will be; it’s a random existence under core energy, possibly very strong, possibly very weak, or possibly nothing. It’s entirely uncontrollable."

"At this stage, the accessory blueprint is an ’Accessory Original Image.’

"Once an accessory blueprint has been replicated multiple times, it becomes the Accessory Original Image we’re familiar with. Initially, it’s only small-scale replication; scientists from the Mechanical Civilization would use the replicated accessory blueprint to first craft an accessory, upgrade it to Level 10, Level 20, and observe the Supermodel Effect."

"If the Supermodel Effect is satisfactory, the accessory original image is retained and introduced to the market for widespread use."

"If the Supermodel Effect is disappointing, the accessory original image is destroyed, and another accessory original image is created to obtain a different random Supermodel Effect."

"Generally speaking—"

"Seven-colored accessories and white accessories don’t receive this treatment."

"The process to detect Supermodel Effects requires consuming Murphy Stones, and it’s unnecessary to use Murphy Stones for white accessories unless it’s usable, even if it’s none. Even the Mechanical Civilization isn’t sure of a ’fridge’s’ Level 100 Supermodel Effect."

"Because across the entire Mechanical Civilization, not even Princess Tuo Tuo would consider upgrading a fridge to Level 100, nor has anybody that idle."

"Seven-colored accessories don’t use Murphy Stones to detect Supermodel Effects either; any weapon or accessory classified as ’Seven-color Grade’ by scientists from the Mechanical Civilization demands a lot of resources and time, making it hard to create a second one quickly. So even if the first one encapsulated into the ’Accessory Original Image’ has unsatisfactory Supermodel Effects, it won’t be replaced quickly."

Perhaps because of the large amount of information.

After a brief pause, Ai continued: "It’s noteworthy that the ’Doomsday Cannon,’ regarded as a new-player Divine Artifact by all trains, was randomly given three ’Half Consumption’ Supermodel Effects after being reset 43 times back then."

"This allowed it, as a blue-grade accessory, to rival or even surpass some yellow and even red-grade firepower accessories."
