System: My Doomsday Train-Chapter 807 - 329: "Ascend or Die.

"For example, in a Cultivation Civilization, to become a Fourth or Fifth-level Civilization, it’s fundamentally impossible without consuming tens of thousands of years."

"And in the Cosmos—"

"Space is too vast, distances are too long. Often, exchanges between civilizations are counted in years or even decades."

"Then in the Cosmos, there are many peculiar locations. Perhaps in a resource-poor area, a suddenly discovered planet rich in resources could lead a civilization in that impoverished region to uncover vast amounts of resources through some means, causing an explosive development in the civilization’s strength and level."

"This event is collectively called ’Civilization Explosion’ by all civilizations."

"For Advanced Civilizations, there are many terrifying cosmic events, and the most terrifying is ’Civilization Explosion,’ which often means one’s own civilization might face extinction."

"Those Advanced Civilizations."

"Some have territories spanning tens of millions of light years, even hundreds of millions of light years. Some Advanced Civilizations have a galaxy with a diameter of hundreds of millions of light years; not every galaxy is as small as yours."

"Such a vast territory inevitably means the existence of numerous civilizations within, hundreds of millions or even billions."

"Those Advanced Civilizations can’t possibly eliminate all of these weak civilizations within their territories; it’s an unrealistic task, impossible. The internal regions of all large civilizations inevitably contain countless small civilizations. The Advanced Civilization naturally possesses the high-grade resource mines in these areas, but some corners, like a mining star with dozens of trillion iron mines, are completely ignored."

"These resource-poor areas also become nourishment for these small civilizations."

"A large territory often means extreme difficulty in message transmission, and due to the large size of the civilization, the internal organizational structure is usually quite bloated. Even with using wormholes and other means, conveying a message from the frontier to the political mother planet of the civilization takes at least several decades."

"Decades of time..."

"This means, by the time the political mother planet learns of a ’Civilization Explosion’ occurring within its territorial range, it’s already been decades. Sending the army to suppress it takes another ten-plus years."

"If the first suppression succeeds, it’s fine. If the first suppression fails, by the time the message is returned and the army is dispatched for a second suppression, several more decades have passed."

"Repeated several times."

"Within the territory of a Level 6 Civilization, when a Civilization Explosion civilization suddenly boosts up to a Level 6 Civilization, a great war becomes unavoidable."

"The larger the territory."

"The higher the probability of a Civilization Explosion occurring within."

"Once such an event happens, even if it doesn’t destroy the civilization, it will shake the foundations of the civilization itself, causing considerable damage."

"Thus—"

"’Cosmic Landmine’ was born."

"Its form might be the transformed Stellar Giant Beast you encountered, or it could be other things, but they all share a common trait: normally they remain in a stable state, only when perception detects they will do everything possible to attack the target!"

"Advanced Civilizations deploy these landmines in various areas within their territories, including areas near their territories, to ensure their ruling position and to maximally guarantee that civilizations within their territories won’t undergo Civilization Explosion events."

"Generally speaking."

"To have the capacity to detect this Stellar Giant Beast, they basically possess Doppler Radar of Level 200. This value is precisely the upper limit that a Third-level Civilization’s resources can achieve."

"If the radar grade is relatively low, the detection range is only 0.1 light years. If it’s under Level 200, a Doppler Radar of Level 100 has a detection range of only 100 light years."

"Which means."

"All Advanced Civilizations almost universally expect that as soon as a civilization within their territorial field advances to a Level 3 Civilization, it must be destroyed immediately to prevent future troubles, the ’Cosmic Landmine’ is for this purpose."

"As long as you don’t detect it, nothing happens."

"When you see it, your civilization faces Doomsday."

"Those Advanced Civilizations won’t allow others the privilege of gazing at the starry sky."

"The moment you look up at the starry sky, the depths of the Cosmos have issued a warrant for your pursuit."

The elder explained clearly and plainly, though he was only a leader of a Third-level Civilization, he obviously knew far more than other leaders of Third-level Civilizations.

"..."

Chen Mang sat silently on the chair, after a long while, he lightly said: "Now, what if this Advanced Civilization happened to place this ’Cosmic Landmine’ within a few light years of me, and my radar is merely Level 100, with a detection range of 100 light years, I’ve detected it, and the ’Cosmic Landmine’ perceives my detection, coming to destroy my civilization."

"Is this considered a bug?"

"I don’t have a Level 200 radar, only the deployment location is relatively close to me."

"It’s not a bug, you’re just unlucky." The elder said quietly: "See the Black Hole in that Stellar Giant Beast’s mouth, that Black Hole maintains its energy consumption, which is considerable consumption for Advanced Civilizations, a waste for them."

"..."

Chen Mang looked at the terrifying Stellar Giant Beast on the screen again, paused briefly before speaking: "So, the ’Cosmic Landmine’ deployed by Advanced Civilizations targets Third-level Civilizations."
