System: My Doomsday Train-Chapter 981 - 368: "If You Can Draw This Bow...

"Kasha civilization?"

Chen Mang nodded thoughtfully, standing on the street and looking around. At this time, he was already on a planet within the "Rough Civilization." It wasn’t a commercial planet created as the focal point of a star system, nor was it a tourist planet bustling with people.

It was certainly not a military or industrial planet.

Just an ordinary residential planet.

There was nothing noteworthy about it.

Its only duty was to provide residence for a batch of Rough Civilization’s inhabitants, but such planets often better reflect the grassroots life of a civilization.

Kasha civilization.

He remembered this civilization as it was one of the most powerful he encountered after leaving the Water Blue Star. At that time, the Kasha civilization seemed god-like to him, an almost completely unstoppable force.

He naturally knew that this civilization had a very low birth rate. Yet, even the Kasha civilization hadn’t found an answer; he just hadn’t expected it to be the doing of the "Cyan Mountain Civilization."

"They’ve certainly got a long reach."

"How was it done?"

"A virus transmitted through sex."

"Sex? If that’s the mode of transmission, it shouldn’t spread that widely. To reduce a race’s birth rate, the virus would need to affect at least 90% of the population. HIV is also transmitted sexually, but we don’t see 90% of a race infected with HIV."

Chen Mang shook his head, "From what I know, the Kasha civilization was just a bit corrupt internally, with no excessively promiscuous behavior. There must be other ways it spreads."

Ai nodded and continued, "It’s indeed not entirely sexual. The virus created by the Cyan Mountain civilization doesn’t need actual sexual contact to transmit. As long as you have sexual fantasies about someone, it transmits with one hundred percent certainty."

"For example—"

"You see a beautiful woman on the street, and some inappropriate ideas arise suddenly in your mind. Even though you wouldn’t act on them, not even approaching the woman or taking further actions, the virus is transmitted at that moment of thought."

"Celebrities were among the first victims."

"Moreover..."

"Teenage boys and girls often have fleeting inappropriate thoughts about their parents, cousins, and other relatives during puberty. These never-to-be-acted-upon sexual fantasies are a normal part of adolescent development."

"But under this virus, it becomes abnormal."

"According to data from the Cyan Mountain civilization, a person, regardless of gender, on average, will only have actual physical relationships with six people in their lifetime."

"But at least with 3929 people, they will have had fantasy sexual relationships."

"Therefore—"

"This mode of transmission almost instantly engulfed the entire Kasha civilization. The Cyan Mountain civilization, after finding it quite effective, then targeted the ’Rough Civilization’ upon refinement."

"That last part is my guess. No concrete evidence shows Cyan Mountain civilization handled it very cleanly."

"Understood."

Chen Mang nodded slightly, looking up at the stars overhead, "So the reason Cyan Mountain civilization has attacked the Nia Star System is not only to eliminate the potential danger of Human Civilization but also to completely erase the Nia Star System."

"The Nia Star System probably still holds evidence of the ’Cyan Mountain Civilization’ targeting the ’Rough Civilization,’ including traces from that experiment on the Kasha civilization."

"Cyan Mountain civilization is worried that Human Civilization’s rapid development will attract Rough Civilization’s attention, thus exposing this incident."

"Although the Rough Civilization now lacks leadership—"

"If they knew what Cyan Mountain civilization did, their furious retribution could easily annihilate Cyan Mountain civilization."

"No wonder..."

"No wonder Cyan Mountain civilization is willing to take such a big risk to destroy the Nia Star System."

"That bit I don’t quite understand," Ai voiced her confusion. "Logically, Cyan Mountain civilization handled it quite thoroughly, leaving almost no information within their own civilization. Surely any evidence in the Nia Star System should have been cleaned up too. Is it necessary to take such a big risk to come here specifically?"

"Yes."

Chen Mang nodded slightly, "Every unfaithful person deletes their infidelity evidence meticulously, but when their partner checks their social accounts or frequently used devices, they’ll still feel anxious, wondering if they’ve truly erased everything."

"Cyan Mountain civilization panicked."

"So they chose to render my Nia Star System into two dimensions, ensuring no oversight."

"The more I think about it, the angrier it makes me, damn it..."

...

Although there’s no concrete evidence of the Cyan Mountain civilization’s plot, it’s roughly pieced together now.

If...

If he leaked this information to the Rough Civilization before going to war with Cyan Mountain, they probably wouldn’t even need him to lift a finger. Of course, he wouldn’t do that; doing so would mean handing over all his resources to others.

"..."

Chen Mang walked through a city on this planet known as "Qiu Mountain Star." People on the road occasionally cast strange glances at him. Their gaze was not hostile, just somewhat curious.

The races within the "Rough Civilization" are not of the Human Race, but the "Star Arrow Race."

Initially appearing as ordinary humans before selecting to become god’s chosen.

Upon becoming a "Berserker," their physique quickly transforms to be red, burly, and tall, looking extremely robust.

While those who become "Divine Archers" will exhibit a tall, slender physique, with pointed ears and a third eye on their forehead.
