My Doomsday Train

Of the seven essential vehicle components for upgrading the train, he had already created the "Generator" and "Circuit System," but hadn't put them to use yet, as he didn't have any spare energy stones.

As for the "Energy Stone" on Boss Kun's train, he had tried to pry it off, but couldn't budge it at all.

Clearly, it wasn't the kind of component that could be removed.

He didn't dare swing a pickaxe at it either, fearing it might explode and leave him stranded there.

Of the seven essential vehicle components for upgrading the train, he hadn't yet created the "Purified Water Filter," "Wind-Fire Wheels," "Steel Car Armor," "Pickaxe Production Line," and "Axe Production Line."

He needed to quickly upgrade the train to level 2 to avoid breaking down halfway.

He wasn't short on purified water for the time being, armor was too expensive, and he had plenty of pickaxes confiscated from enemies, so he would have to start by building a Wind-Fire Wheel to increase the train's speed.

When capturing enemy trains, some vehicle components could be removed, such as the "Triple-Legged Gatling Gun," but many more couldn't be detached, like armor and Wind-Fire Wheels.

Wait—

Just then.

Chen Mang suddenly thought of something: he wasn't short on pickaxes at the moment, but if the Pickaxe Production Line was upgraded, would the pickaxes produced mine faster?

He quickly returned to the train car and opened the "Newbie Guide" on the control panel. After swiping around the screen for a while, he finally found the information he wanted in a corner.

-

"Pickaxe Production Line," Green quality, maximum level 3. Each upgrade allows the production of pickaxes capable of mining higher-level mines.

-

Only mine higher-level mines?

Chen Mang frowned slightly as he looked at this line of text. It wasn't useless, at least in the future, it seemed he would be the only one who could freely mine level 4 and above mines. Even if others obtained level 4 pickaxes, they probably wouldn't be able to do it as easily as him.

But it was still somewhat different from what he had imagined.

There was a slight discrepancy.

He wondered if level 4 iron ore could replace level 1 iron ore.

Soon—

He found the information he wanted in the Newbie Guide.

-

10 units of level 1 iron ore = 1 unit of level 2 iron ore.

10 units of level 2 iron ore = 1 unit of level 3 iron ore.

10 units of level 3 iron ore = 1 unit of level 4 iron ore.

On the "Crafting Table," 10 units of level 1 iron ore can be synthesized into 1 unit of level 2 iron ore, or 1 unit of level 2 iron ore can be broken down into 10 units of level 1 iron ore.

-

This time!

Chen Mang smiled with satisfaction. That meant that as long as he found a level 4 mine and upgraded the "Pickaxe Production Line" to level 4, every 1 unit of level 4 iron ore he obtained would be equivalent to 1000 units of level 1 iron ore.

That made the problem much simpler.

He only needed to find a "Level 4 Iron Mine" to solve his current resource shortage.

There were basically two ways to find mines.

Ask other train captains on the "Train Radio," or use the "Resource Detection Radar" to detect nearby resource areas while traveling. Both of these components were available for crafting after the train was upgraded to level 2.

"Purified Water Filter," "Wind-Fire Wheels," and "Pickaxe Production Line."

He placed the filter in the No. 3 living car, and the pickaxe production line in the No. 2 warehouse car. The car layout wasn't perfect yet, but he didn't have any other resources to build extra cars, so he could only make do for now. He would rearrange them carefully when he had more resources in the future.

These three components cost him a total of 700 units of iron ore.

He was completely broke now. He didn't have even 1 unit of iron ore left.

Producing a pickaxe required 10 units of iron ore.

The "Purified Water Filter" could filter all liquids, such as urine and rainwater, into drinkable purified water. The shape was also quite disgusting, a bit like a toilet. After upgrading to level 2, it could directly produce mineral water, each bottle requiring 1 slice of moldy bread.

The Wind-Fire Wheels had already automatically replaced his existing ordinary wheels.

They significantly increased the train's speed.

But the downside was also obvious: they were basically unable to pass through when facing zombie hordes or some bad terrain, and the risk of overturning was very high.

Thus—

He was still missing two essential components for upgrading the train: "Steel Car Armor" and "Axe Production Line."

The "Steel Car Armor" was the most expensive of them all, requiring a full 1000 units of iron ore. What was even worse was that it was calculated per car, meaning 1000 units of iron ore could only cover one car with armor.

To cover all the train cars with armor, he would need even more iron ore. Fortunately, as long as any one car was covered with armor, the train upgrade requirements would be met.

No wonder Boss Kun's train only had armor on the engine.

"So anxious."

Inside the train car, Chen Mang looked out the window at the mine and sighed helplessly. The slaves were still mining in the mine and wouldn't be out for a while. He was tempted to grab a pickaxe and join them.

He needed more slaves!

Oh no.

He had to change that habit in the future. According to Old Zhu, they should be called passengers and survivors.

There wasn't nearly enough iron ore.

It was a pity that he wasn't qualified to build a "Train Radio" yet. Otherwise, he really wanted to know what other train captains did when they lacked resources. There wasn't enough information exchange.

But he suddenly remembered something. He didn't know if...

His "Geothermal Furnace" could refine all the confiscated pistols and pistol bullets.

No sooner said than done.

He immediately walked down from the train car and activated the "Geothermal Furnace." With the opening of the blood basin mouth, he threw a pistol in and quickly obtained 10 units of iron ore.

"Hmm."

Chen Mang curled his lips. It was a bit little, but it was okay. Every little bit helps. Then he threw in all the confiscated pistols and over 200 pistol bullets, immediately obtaining a total of 250 units of iron ore.

He had kept the "GLS pistol" he initially obtained, along with thirty-odd bullets.

Although he no longer needed it, since he had the assault rifle, which was a better weapon, it was, after all, the first lifeline he had obtained in this world, and it was good to keep it as a memento.

He had to build a safe train of his own as soon as possible. Otherwise, if he encountered a zombie horde forming a encirclement again, he would probably have to disconnect all the cars and flee.

If the train was strong enough, why would he run!

He would slaughter them all and maybe get a lot of good stuff!
