My Doomsday Train

Chen Mang looked at the bread slices that were produced again, took one in his hand and examined it carefully. After casually putting the bread slice into his mouth, he looked at the other components.

After the "Moldy Bread Slice Production Line" was upgraded to level 10.

Not only did the taste and flavor change, but there were also two special supermodel effects. Long-term consumption could ensure that his slaves would basically not get sick, and it could also slightly enhance their physical fitness. Although it was unknown exactly how much it would enhance, judging from the word 'slightly,' it probably wouldn't be much.

Most importantly.

The price didn't change.

It was still 1 unit of iron ore for 10 slices of bread.

More for the same price, not bad.

He currently had 3927 units of iron ore left. He wanted to upgrade all the components to level 10, such as the "Telescope," and the "Refrigerator" and "Cola Production Line" that he hadn't built yet.

The latter two components were non-essential components to build when the train was at level 1.

At that time, he didn't have many resources, and these components weren't essential, so he temporarily put them aside. Now that he had enough resources, he would naturally make up for all these components.

At this point.

All the buildable components of the train had been built by him.

Just as the slaves were scratching their heads in confusion, looking at each other, the train door of the No. 3 living carriage was suddenly opened. Several baskets were filled with soft bread slices containing jam, and Chen Mang also walked out at the right time, leaning on his cane and standing at the train door, looking at the slaves in front of him with excitement in their eyes, and the slaves behind him who were standing on tiptoes, eagerly wanting to see what was happening. He smiled and raised his hand.

The scene instantly quieted down.

"From now on."

"This will be your daily food, delicious bread with jam."

"This is my sincerity."

"If you want to always have the best treatment, I hope to see your sincerity. Repay me with resources, and I will not mistreat anyone."

"Now, let's eat."

He waved his hand, and Lao Zhu and the others stepped forward to carry the baskets full of bread down and prepare to distribute them. He then walked to the front of the train alone, considering whether to add another carriage.

There were a bit too many things in the train.

It was a bit inconvenient to always have Lao Zhu and the other thugs stay in the same carriage as the bread production line. There was also copper ore here, and he would definitely have to build enough bullets as a reserve later.

Then the No. 2 cargo carriage couldn't put some production lines and mineral resources together.

Give the "Pickaxe Production Line" and others a separate carriage, then the bullets and mineral resources a separate carriage, and the thugs a separate carriage. He would see about this in a few days.

Three days passed like this.

During these three nights, Chen Mang would look up at the starry sky, the stars forming that string of words. Whether it was the position or arrangement, there wasn't much change. After nightfall, those stars would always reappear.

During these three days.

He saved a lot of iron ore, basically spending none of it. Adding to the original accumulation, he now had.

"43091 units of iron ore."

It was an astronomical figure. This was the first time he had accumulated such a large amount of iron ore. It was almost enough to buy a Ji Chuchu.

And he set his sights on—

"Train Steel Armor" and "Wind Fire Wheels."

These two green-grade components were what he wanted to build first. The former determined the train's defense, and the latter determined the train's speed.

As of now.

The "Stellar" train, including the train head, had a total of five carriages. Each carriage was covered with a layer of sturdy level 1 train steel armor. Upgrading one carriage armor to level 2 required 5000 units of iron ore.

A total of 25,000 units of iron ore were spent.

All "Train Steel Armor" was upgraded to level 2 armor.

In the night.

Chen Mang walked down the train, gently stroking the armor on the outside of the train, which had obviously become darker, and feeling the strong sense of security it brought. With this, the damage from level 2 monsters could basically be completely ignored, and ordinary zombie hordes could no longer do anything to him.

As for level 3 armor.

This would be considered in a few days. Upgrading one level 2 carriage steel armor to level 3 would consume 10,000 units of iron ore, which would add up to 50,000 units of iron ore, just enough for a Ji Chuchu.

The price of upgrading train defense was the highest.

This was also the most expensive upgrade price among all green-grade components.

After upgrading the armor.

He turned his attention to the "Wind Fire Wheels." The price of upgrading this thing was also not cheap. Upgrading from level 1 to level 2 required 1000 units of iron ore.

He consumed 10,000 units of iron ore and upgraded this component to level 5 in one go. He couldn't afford to upgrade to level 10, he didn't have enough resources.

The main shape of the Wind Fire Wheels didn't change much.

The base speed increased.

The advantage of "Wind Fire Wheels" was that they could maintain the fastest speed of the same level on the wasteland. The basic effect added 30km per hour to the fastest speed.

Each level added 20km per hour to the upper limit speed.

After upgrading to level 5, it directly added 100km per hour to the upper limit speed. In addition, after upgrading to a level 2 train, the train's basic upper limit speed was 130km per hour.

Adding the Wind Fire Wheels, and considering its own weight and other reasons.

The information given by the "Train Auxiliary AI" on the control panel was that the current upper limit speed of the Stellar train was—

254km/hour.

Before the upgrade, it was 156km/hour, almost twice as fast. This time, if he encountered any irresistible crisis, he would definitely not be the one running at the back.

Especially, when upgrading to level 5, the first supermodel effect was also unlocked.

-

"Wind Fire Wheels Level 5 Supermodel Effect": Can stimulate potential state, doubling the train's upper limit speed, but will rapidly consume energy stones and cause some damage to the Wind Fire Wheels.

-

This supermodel effect could play a big role in saving lives at critical moments.

Chen Mang looked at the train data displayed on the control panel, and remained silent, looking at the "Vehicle Auxiliary AI" component. He could actually guess the supermodel effects of some components.

For example, the supermodel effect of the Wind Fire Wheels must be related to speed.

The supermodel effect of the Car Blade must be related to attack.

But for components like "Refrigerator" and "Vehicle Auxiliary AI," he couldn't guess what their supermodel effects were at all. For example, the refrigerator—

What kind of supermodel effect could this thing have?

He suddenly wanted to try it. Anyway, upgrading white-grade vehicle components consumed much fewer resources than green-grade components.
