CHAPTER 523: CHAPTER 281: "MECHANICAL CIVILIZATION, NOT YET EXTINCT!

He couldn’t contribute much to the conversation here, nor offer any constructive suggestions.

He was able to stand here entirely because Master Mang trusted him.

But he didn’t want to appear brainless, so what he could do was to echo some remarks he found reasonable.

...

"Li Shiji, do you know how many people live on Water Blue Star?"

"The latest data before the doomsday was 14.7 billion people."

"Do you know how many Doomsday Trains there are?"

"I don’t know."

Chen Mang looked at Li Shiji and said softly, "I’ll tell you, when we were still in the Tieling Wasteland, there were 50 million trains. Now, so much time has passed, this number might have decreased, or it might have increased."

"All trains—"

"At least 100 residents are needed to develop smoothly. Otherwise, the progress of mining will be very slow. We’ve only started selling ’mining robots’ recently, and not many have been sold."

"I can be more specific, ’mining robots’ are gold-grade components, extremely rare, not a component every train has."

"Calculate this, the 14.7 billion people, spread across the 50 million trains, approximately how many people can each train have."

"294 people."

Before Li Shiji could speak, Ai provided an accurate answer.

When it comes to calculations, no one on the entire train could be faster than him!

"Good."

Chen Mang nodded slightly again: "This 14.7 billion figure is the latest pre-doomsday population data, and one year after the doomsday outbreak, the number of trains was 50 million. During this year, some people must have died, right?"

"You should be able to sense what the death rate is."

"Assuming the most conservative death rate, half died, only a 50% death rate, which is 7.35 billion people, and then subtracting the population of 50 million train captains, the remaining population is exactly 7.3 billion."

"This means, on average, each train could have 146 people."

"It is no exaggeration to say... if every train had this population, I have reason to believe, 99% of the trains would have long been doomed. This number of residents can hardly maintain the normal mining needs of the train, too few, maybe enough initially, but not enough with a little development."

"So—"

"I have two possibilities here."

"The first possibility, at that time, among the 50 million trains in the Tieling Wasteland, two-thirds of the trains were newly crafted level 1 trains, and there weren’t many people on those trains, and the remaining population was evenly distributed among the rest of the trains."

"The second possibility..."

Chen Mang paused and didn’t continue.

Li Shiji had a flicker of an idea in his mind and picked up the conversation, a bit startled: "The second possibility is that these 50 million trains might not only have included those on Water Blue Star, but also trains on other planets?"

"Other planets also experiencing doomsday?"

"Yes." Chen Mang nodded slightly and said softly: "That possibility exists, which is why I place so much importance on this ’Withered Wood Spring’ Adventure Map, because if it really is this possibility, then ’Tuo Tuo’ Mechanical Princess would certainly not just select the smartest from one planet but from multiple planets."

"If we could connect with train captains on other planets also experiencing doomsday."

"Then we could send out the ’Neon City Entry Ticket’ and see if we can try to link up the networks in Neon City to other planets, building bigger and stronger connections!"

"..."

Li Shiji fell into a complex silence for a long time before finally saying, "I actually want to say that before the doomsday, the Federation did not detect any planets with characteristics of life near Water Blue Star."

"A civilization level crushing us isn’t in the same league, let’s not think about these things."

Just as a few people were talking.

The badge always flashing in the drawer suddenly shattered, countless tiny red dots emerged from the badge, forming a dark red Teleportation Gate in front of the train, slowly rotating, as alluring as a black hole stained with fresh blood.

Everyone fears black holes.

But...

Who wouldn’t want to keep a black hole at home in a fish tank, it would look really beautiful, looks so tempting, you want to take a bite.

...

Chen Mang didn’t speak again.

Instead, he sat in his chair, slowly pushing the control lever, the train slowly drove into the dark red Teleportation Gate ahead, re-entering the ’Withered Wood Spring’ Adventure Map.

Like a baby seeing the world for the first time, everything in front of his eyes suddenly opened up vastly.

The Constant Star Train appeared on a plaza.

A huge plaza.

As large as several football fields, the plaza was surrounded by a white mist, at a glance all you could see was this plaza and the 19 trains of varying designs stationed on the plaza.

The Target Detection Radar was disabled.

Chen Mang looked at the control panel screen, his Target Detection Radar and Resource Detection Radar were both disabled, he couldn’t see the other trains’ component levels, but they all looked very strong.

These 19 trains, were all expanded.

It’s just that the number of carriages was quite short, basically including six or seven carriages with the train head, and the most having nine, while the Constant Star train had 15 carriages including the train head, not counting the Giant Beast carriages.

His train was the largest with the most expansions here.

It looked extremely conspicuous.

Big, long.

As if he were the flagship of a fleet, and the other trains were just his escort ships, completely not in the same league.

The 19 trains were laid out in a fan shape on the plaza, although he couldn’t see the normal conditions inside the other trains, he could vaguely feel that many people were watching him, more precisely, they were watching his Constant Star Train.
