The "Survival on the Train" game has bugs, it's really laggy!

While the materials were being processed over a low flame, Su Yuan opened the trading platform again.

The ingredients are all ready, but the problem of "food" for Xiao Huo is still unresolved.

I promised it I'd get some good fuel, so I can't go back on my word.

This time, he directly entered keywords such as "fuel," "coal," and "charcoal" into the search bar.

The search returned quite a few items, but most of them were ordinary firewood with low calorific value and poor cost-effectiveness.

Coal and charcoal were also sold, but at exorbitant prices. They were usually traded for weapons or large quantities of food, clearly indicating that they were being hoarded as strategic resources for speculation.

"This is outrageous! The price is almost as high as the food itself."

Su Yuan cursed under his breath, and then, just like last time, changed his approach and started filtering from the other items.

However, he didn't have a specific target, so he could only keep searching and looking.

Just as Su Yuan was about to lose patience, a product with a peculiar design caught his attention.

It was a photograph. The photograph showed a bunch of dark, greasy things that looked like seaweed, with a layer of shiny crystals on the surface.

[Item Name: Black Seaweed?]

[Seller's message: I don't know what this thing is either. The last stop was a bay, and it was full of these things, not a single fish! I caught some and tasted it; it was salty and bitter, completely inedible! But this thing burns incredibly fast, it ignites instantly, and it produces black smoke, like burning a tire! I have plenty; anyone who wants it can take it, I'll trade it for some food, I'm starving!]

Upon seeing this message, Su Yuan's heart skipped a beat.

Because in his line of sight, that familiar hidden note reappeared.

[Hidden Note: Heavy oil seaweed, a type of algae that mutated under special conditions, is rich in high-calorie oils. Its calorie value is three times that of high-quality anthracite coal, making it an excellent core energy fuel. Disadvantages: It produces a large amount of dense smoke when burned, with a very pungent and unpleasant odor. It also contains trace amounts of toxins, and the cumulative effects of long-term ingestion should not be ignored.]

Its calorific value is three times that of coal!

Su Yuan's breath caught in his throat for a moment when he saw those words.

This isn't seaweed! It's practically solid petroleum!

He quickly contacted the seller, a man named Sun Qiang, who replied to messages almost instantly, seemingly very hungry.

Originally, things that could provide energy were in high demand. Although the energy cores could not be fed too much, you would still consume their energy when you smelted things, which would inevitably lead to a decrease in train speed.

However, the downside of this thing is that it produces a lot of thick smoke and is slightly toxic. In the early stages, everyone was just an ordinary person, so they couldn't withstand it at all.

Only someone like Su Yuan, whose abnormal physique relies on exploiting bugs, is fearless.

The other end replied almost instantly, their words conveying a sense of urgency.

Sun Qiang: "Bro! You want this? Great! Let me tell you, I have tons of this! How much do you want? I'll trade it for food! Bread, biscuits, instant noodles, anything! I'm starving!"

Upon seeing this, Su Yuan immediately typed back: "This is a good thing, but you probably know why it's been sitting in my hands until now."

Sun Qiang: "This..."

Clearly, he must have tried it, and he tried to downplay the seriousness of the issue in his description.

However, some buyers who approach him are not fools. No one will buy a lot right away. Instead, they will make an initial transaction and then make a second, larger transaction after confirming that the items are suitable.

In the end, only a small piece was traded back, and the smoke from it almost choked people to death, so the transaction was naturally terminated.

After all, can you accept a car full of smoke, especially since the smoke is slightly toxic and has a strong smell of burning tires?

Su Yuan: "How about this, I don't have much food myself, but I can trade you some tools..."

Sun Qiang: "Okay...okay then."

[Transaction successful!]

In the end, without much haggling, Su Yuan successfully obtained 100 jin of heavy oil seaweed from the other party.

The price paid was a pickaxe and a cigarette.

Just then, Little Fire's voice rang out again, full of joy, because it could sense that its master had traded something, something dark and indistinct.

Could it be for myself?!

【Master, everything here has been taken care of.】

【ding dong——】

[Smelting successful!]

Congratulations! You have received: 4 units of iron, 3 units of plastic, 3 units of copper, and 1 electronic component.

Su Yuan was overjoyed to see that all the materials were finally gathered.

He walked over, picked up a unit of seaweed, weighed it in his hand, and then threw it directly into the small fire's feeding port.

One unit is 1 kilogram, and Su Yuan managed to get a full 100 jin this time, which is equivalent to 50 units.

The train's storage space is 100 units, and the maximum capacity of one unit depends on the items.

Food and ingredients are filled with 99 units per slot, tools are filled with 9 units per slot, and some special items will occupy 1 slot on their own.

Therefore, the train still has plenty of storage space.

"Come on, I'll keep my word and try your new food."

[This...this is for me?]

Little Fire was stunned for a moment. Clearly, this happiness came too suddenly, catching it somewhat off guard.

"What's wrong?"

"If you don't like it, then I'll take it away."

【Yes, I love to eat! Thank you, Master!】

Xiao Huo, realizing what was happening, immediately panicked.

The heavy-oil seaweed is ignited instantly as soon as it enters the feeding port.

"boom--!"

A burst of intense energy suddenly erupted.

The small flame's core suddenly swelled up, causing the temperature in the entire cab to rise sharply!

An unprecedented surge of power erupted from the core of the flames and spread throughout the entire train!

However, at the same time, side effects also appeared. Thick smoke began to fill the entire carriage, and even Su Yuan felt his eyes were stimulated and couldn't help but squint.

He could imagine the scene of those other people cursing and swearing as they used Sun Qiang's heavy oil seaweed.

Well, you really have to bear the side effects of this stuff on your own.

【ding dong——】

The energy core "Little Flame" has consumed high-calorific-value fuel, significantly increasing its energy reserves!

[Note: Currently, 50 km/h is the limit that a Class I train can handle; the speed cannot be increased further.]

At the same time, Xiao Huo let out an extremely pleasant cheer.

[Oh my god! This! This is it! It's amazing! Master! I love this thing! Give me more! I feel like I can go even faster!]

Su Yuan: "..."

It seems the next goal is to find a way to upgrade the train.

Now that we have all the materials, let's build!

Su Yuan took the blueprint out of his pocket, and sure enough, a prompt flashed before his eyes.

[All materials needed to manufacture the "Platform Forecaster" have been collected!]

Iron: 5/5

[Plastic: 3/3]

Copper: 3/3

[Electronic Components: 1/1]

[Should materials be consumed to manufacture a "Platform Forecaster"?]

"Make it!"

Su Yuan confirmed without hesitation.

As soon as he finished speaking, the blueprint card in his hand instantly turned into a blue light and floated in mid-air.

Immediately afterwards, the iron blocks, plastics, copper, and electronic components in the warehouse transformed into streams of light, flowing into the blue light like rivers flowing into the sea.

The blue light contracted and expanded violently, as if something was rapidly taking shape inside.

The whole process lasted about half a minute.

As the light faded, a sophisticated and technologically advanced instrument quietly floated in front of Su Yuan.

It is hemispherical in shape, with a metal base that can be perfectly embedded into the reserved interface of the driver's console. The upper part is a transparent cover with a complex three-dimensional projection structure inside.

Congratulations! You have successfully created a "Platform Forecast Device"!

Please select an installation location.

"Install it on the driver's seat!"

The instrument transformed into a streak of light and instantly flew towards the cockpit, fitting perfectly into a circular groove in the center of the control panel.

"Buzz—"

With a soft click, the platform forecaster was activated.

At the same time, a new section has been added to Su Yuan's train control interface - [Platform Forecast].

With excitement, Su Yuan strode to the dashboard and tapped the new icon.

Instantly, a brand new information interface appeared before his eyes.
