System: My Doomsday Train

As for the "Sunflower Seed Production Line," it's purely a lifestyle product.

Unlike cola tea leaves which have some special effects, it is purely an enjoyment accessory. 100 units of iron ore can produce 1 jin of sunflower seeds, guaranteeing the best taste for every seed with this supermodel effect that he really likes.

Two of the foods he dislikes the most are—

Clams and sunflower seeds.

It's not that they taste bad, in fact, he thinks they taste quite good.

But eating them feels like playing Minesweeper; no one knows if the next bite will be full of sand or bitterness.

It's like playing Russian roulette.

It's all about gambling.

...

"Not bad."

Chen Mang leaned back in his chair and withdrew his gaze from the five white-grade accessories, finding them all quite useful and to his liking.

As for the rest of this haul—

"Doomsday Marriage Certificate" *3.

No need to say much about this, just toss it in the drawer and use it when couples appear on the train. Best for those in the honeymoon phase, since generally speaking, there are quite a few couples genuinely in love during that period.

"Custom Screen Production Line Blueprint."

Consumes 12,000 units of iron ore to create and upgrade to Level 10, gaining two supermodel effects.

–

"Custom Screen Production Line Blueprint Level 5 Supermodel Effect": Naked-eye 3D immersive experience.

"Custom Screen Production Line Blueprint Level 10 Supermodel Effect": None.

–

This accessory's upgrade effect improves screen quality with each upgrade until it is high-definition.

It's a bit cheaper than using a Mechanical Heart to manufacture screens.

"..."

Chen Mang thoughtfully nodded, planning to spend tens of thousands of iron ore units to make a big screen in some time, allowing all train residents to watch some films together outside the train to relax.

To work well, it's not enough to focus only on physical health; mental health must be considered too.

As for the remaining haul.

"Neon City Free Entry Ticket" *3.

These were also tossed into the drawer.

There were only three left, so they had to be used sparingly. They were not available for purchase in the store, so once these three were used up, there might not be another chance to go to the "Neon City."

"Insurance Room Key Card": Special Tool.

This tool is used to unlock a safe box in the "Neon City" adventure map, but it's not needed yet. When returning to this map, they can look for where the safe box might be; however, finding a safe in such a large city is no easy task.

"Robot Parts Gift Package."

This he immediately tossed to Ai, as a gift for Ai.

Finally, the two main events!

The two most expensive accessories!

Blue-grade accessory "Solar Energy Panels Blueprint."

Special accessory, "Machine Gun Structure Armament Module."

After consuming 110,000 units of iron ore to upgrade the "Solar Energy Panels" to Level 10.

Two supermodel effects were gained.

——

"Solar Energy Panels Level 5 Supermodel Effect": Can still obtain energy at a slower speed at night.

"Solar Energy Panels Level 10 Supermodel Effect": Surplus energy will be converted into Energy Stone.

-

This accessory is quite useful.

It can maintain the normal operation of all accessories on the train by absorbing solar energy during the day. The higher the level, the greater the absorption speed and capacity, with surplus energy being convertible to Energy Stone.

Especially the Level 5 supermodel effect.

It can absorb solar energy at night, though at a slower speed.

"Pretty good."

Chen Mang smiled as he looked at the information on the console screen. The Level 10 "Solar Energy Panels" during the day could almost cover all the train's accessories for normal daytime use, accounting for about fifty percent.

This includes a series of accessories that need to remain on continuously, such as food, central air conditioning, target detection radar, oxygen generator, mechanical eye, etc.

With more than 1,900 additional survivors, his daily iron ore consumption is about over 6,000 units.

Equivalent to saving him 3,000 units of iron ore daily, which means he can manufacture 6 Level 1 Energy Stones each day.

It would pay for itself in less than a month.

This accessory should be prioritized for future upgrades to aim to completely cover the train's daily consumption, easing the iron ore pressure. This way, even if they encounter unforeseen events and can't mine iron ore for ten days to half a month, as long as the sun rises regularly, the train's basic operations can still be maintained.

If the sun doesn't rise...

Then there's no need to consider this at all.

That would truly be the end of the world, and survival with the train would be difficult.

As for the last special accessory, "Machine Gun Structure Armament Module," it's temporarily unusable as it requires a Level 8 train. He purchased it purely because of the simple, unadorned statement on the product information.

"Can greatly enhance the machine gun's power."

That's why he placed the order.

Those were all the gains from this "Neon City" adventure map.

...

"Phew..."

Chen Mang lay back in his chair, exhaling a sigh of relief. For now, he had nothing that needed his attention, so he just had to wait for Er Dan to come by. He had nearly two hours of free time.

A perfect time to watch a movie.

And to try out what this so-called naked-eye 3D immersive experience is like.

He immediately consumed 900 units of iron ore to create a big screen and had Ai set it up inside the train compartment.

"Seen them all..."

He rummaged through the drawer. The films and shows scavenged from the last city visit he had mostly watched, leaving nothing new. It seemed like another trip would be necessary to gather some lifestyle entertainment supplies.

The "last one."

He found a romance film and, after some hesitation, chose to play it.

Normally, he doesn't see himself as someone who would watch a romance film.

Not that he dislikes them.

It's just that he finds them a bit boring.

But there were no other choices, and he didn't want to rewatch movies he had seen before, so he ultimately made a compromise.

"Wow."

The film had just started, and Chen Mang couldn't help but exclaim in amazement. The naked-eye 3D effect was indeed impressive, giving an immersive feeling. Of course, the effect wasn't as realistic as the "Combat Training Virtual Space," not even close, but it was already quite good compared to a regular screen.

...

"Pig Train Captain, you're looking for me?"

In the resident carriage, a rather handsome young man cautiously approached Old Pig and asked.

"Mm."

Old Pig smiled at the boy in front of him, "During the last background check, didn't you say you're a novelist? I read the beginning of your new novel, and it's quite interesting; many residents like it too."

"You don't have to mine anymore in the future."

"Here."

He gestured, and Li stepped forward to hand over a mouse, a keyboard, and a screen that was the size of a notebook. "You'll just be responsible for writing novels in the future, 20,000 words a day."

"For every additional 4,000 words over 20,000, you'll get an extra Fixed Star Coupon."

"But no nonsense writing."

"Rebuilding a civilization involves not just enhancing combat power; entertainment products also need to be passed down. That is your task, a big responsibility, do your best."

"Ah..."

The young man was slightly taken aback, looking at the keyboard and screen before him and tentatively saying, "Pig Train Captain, the computers I used before all required a mainframe. Is this computer without a mainframe... high-tech?"

"Naturally."

Old Pig laughed, "This screen connects to President Ai; Ai is the mainframe. Your future work involves this. Any other questions?"

"Uh..."

After a slight hesitation, the young man continued, "Do I need to integrate any values content into the novel?"

"Such as?"

"Like about Master Mang."

"Tsk." Old Pig patted the young man's shoulder, "No need for now. You just need to write interesting stories, interest is most important."

"Off you go."

Then Old Pig watched the young man's back, sighed lightly, and strode toward his private room in Guard Carriage No. 7, as he still had unfinished work. This time, it was pretty tricky.
