"Why did prehistoric civilizations come to Earth? Scientific expedition? Explore? Or is it being chased and fleeing? In any case, the idea that prehistoric civilizations were not the inhabitants of the earth has slowly been accepted by most people, but the extreme genetic similarity with humans does not allow us to simply classify them as 'aliens', so the term 'prehistoric civilizations' has been retained. ”

-- Nutshell article: "Why is it called a 'prehistoric civilization' even though it is an alien life?" 》

***

"Now where we are is a cargo terminal." Jiesi pointed to the prehistoric civilization text on the ground, "To be precise, it is the mineral dock, the space mining ship is unloaded in the airlock where we entered, and then transported to the smelting center by the machine on the upper level, and the steel is transported to this layer, and then to the production workshop you saw before, the production efficiency is terrifying." ”

"I didn't find out last time." Ling Yu shook his head, "If I see it, I can take a picture for you." ”

"You don't understand the culture of prehistoric civilizations, boss, and you don't understand the structure of the spaceship, you don't understand where they will write the signs, not to mention, this is a spaceship that has been parked for more than 100,000 years, and many things have been damaged, disappeared or even hidden, just like this signpost, if I don't come, you can't find it if you walk around tens of thousands of times, right?" Although Jiesi's words were harsh, her tone was very soft, which did not make Ling Yu feel uncomfortable.

"Hmm...... That's right. Ling Yu nodded, accepting Jiesi's criticism, and the young man also opened his face armor, revealing his face, "Then how do we go now?" ”

"Here, there should be an emergency evacuation passage out of the airlock, according to what is written on the ground, to the cargo compartment 18-44, the 23rd, 24th, 25th living quarters, the 12th ecological zone and the sixth bridge." Jess pointed to the left of the direction the two were heading, "But it's not that these things are these things as soon as they go out, it's just that they're all in this direction." ”

“…… There are at least six bridges on this ship? Ling Yu was puzzled.

"No, that's not what it means, it's just a habit of prehistoric civilization," Jiesi explained, "The sub-bridges are generally in charge of a certain area, and they can't control the entire ship, similar to the control center of a division, theoretically the main bridge can control all the divisions, but if there is a problem with the main bridge, these sub-bridges can also be used, for example, the Sixth Cambridge should be able to control the living area of 23 to 25...... That's pretty much it. ”

"I see."

Ling Yu nodded, and continued to search and move forward with his gun, and it didn't take long for the two of them to see a small door painted yellow appear on the left side of the passage.

"This is the evacuation route you are talking about," Ling Yu stepped forward and stared at the small yellow door that was basically integrated with the wall - in fact, it was only the color that was different from the surrounding metal walls, and it was impossible for Ling Yu to notice the last time it was not fully illuminated.

"Here, yellow means danger and urgency for prehistoric civilizations, equivalent to our red." Jiesi stretched out her hand and pressed down on the left piece of the wall that did not have any abnormalities, and slid it slightly, revealing the mechanical lock-picking device that Ling Yu had seen last time behind the wall.

"Is this really an escape channel......" Ling Yu expressed doubts and helplessness about the manual door opening device that was hidden so deeply, "How can you notice the manual door opening device of this escape channel in an emergency." ”

"It's because of cultural differences," Jiesi patiently answered Ling Yu's question as she opened the door, "All the escape routes of prehistoric civilizations will be marked in yellow, and the second piece on the left of the inverted triangle wall panel must have a manual opening device, if all are designed like this, then everyone will remember it." ”

"And the enemy ...... The switch cannot be found. ”

Jeuncy's words paused, but Ling Yu felt that Jeuncy seemed to have said something terrible.

Enemy? What enemy? Enemies of prehistoric civilizations?

"I know what you're trying to ask, some things are long, and it doesn't make sense for you to know them." With a crisp sound of metal colliding, the metal plate in front of Ling Yu slowly retracted upward, and the sensor lights inside lit up one by one, revealing a straight ladder downward.

"It's okay, I'm not interested in theoretical knowledge." Ling Yu patted Jiesi on the shoulder, signaling that she didn't have to worry, and then took a step forward and slipped into the door.

"Safety, come down."

The straight ladder down was about thirty meters high, Ling Yu did not slide down directly, but made sure that there was no problem with this ladder that was at least 120,000 years old step by step, and then walked to the bottom, raised the gun, and confirmed that there was no problem, before pressing the communicator.

Jiesi happily slid down the ladder with her hands, and then playfully stuck out her tongue at Ling Yu and looked up at the platform in front of her.

"This is supposed to be a transportation system, and it is documented in the literature." Jiesi walked forward as she retrieved the number from her left eye, "These super-large ships have a levitation transportation system. ”

"Stay behind me." Ling Yu stretched out his hand, stopped Jiesi who wanted to go to the front, and slowly walked to the platform in the distance.

"There are tracks, there are no trains." Ling Yu walked to the edge of the platform, and even those who didn't know anything about prehistoric civilization could see that it was something similar to a subway platform.

"Hmm...... It shouldn't be. Jiesi walked around to something resembling a platform on the side of the platform, and reached out to wipe off the dust about two fingers thick on it, revealing a "piece of paper" that had been almost completely shattered.

"Safety Precautions...... Need to activate ...... 'Avina'? Jess looked at the entire panel, and suddenly showed a sudden expression of realization, "Boss, this way, this way." ”

"What's wrong?"

"Try it, start this."

Ling Yu glanced at Jiesi, nodded, and then pressed his palm into a box next to the control platform.

A burst of light from the electronic circuit flashed under Ling Yu's palm, and the entire panel lit up one by one, and then, a ball of light suddenly appeared in front of the two of them—directly above the control platform.

"It's a hologram." Jiesi grabbed Ling Yu who was holding the gun, "I've seen it on the 'Ark'. ”

"Hmm......" Ling Yu smiled a little embarrassedly, but in the spirit of being cautious, Ling Yu just lowered the muzzle of the gun a little.

At this moment, the ball of light spun around and flew behind the two of them, and immediately after, a stream of jù flashed, and the ball of light turned into a translucent female form floating in the air.

An inexplicable voice came - of course, this was for Ling Yu, Jiesi glanced at the voice's owner, the translucent digital girl, and then turned her head, and a connector protruded from the index finger of the metal's left arm, inserting it into a gap under the control platform.

"Received a command from the bridge and is loading a new upgrade patch."

The translucent girl's figure disappeared in an instant because of Jiesi's movements, and even the ball of light shook a few times, but soon, it regained its brightness and regained its feminine posture.

"Its library has been destroyed, so it's unlikely to answer our secret about where this ship came from," Jiesi gave Ling Yu a not-so-good answer as she operated the holographic keyboard.

But that wasn't really what Ling Yu was interested in.

"Welcome aboard, first mate, it's been 53443233 years since your last landing on the ship, the third planetary autobiographical cycle, which is about 146,419.8 third planetary orbital cycles."

"Load additional patch packs 17 through 51." Just when Ling Yu was stunned, Jiesi spoke, "Remarks, 'The Solar System and the Earth', 'Human Culture', etc. ”

"Loaded, welcome, first mate, it's been 53443233 days since you last boarded the ship, what can I do?"

"This is artificial intelligence?" Ling Yu turned his head sideways, and after getting a nod of affirmation from Jiesi, he was slightly silent for a moment, and gave the first order, "Introduce yourself." ”

"This is a restricted artificial intelligence assistant interface, codenamed 'Avina', my main job is to be responsible for the intelligent management of low subjective initiative on the spaceship, if the permission allows, you can contact the nearby bridge and the main bridge through guò, and I can manage and control all the equipment in the area."

"It seems to be...... Very convenient system. Ling Yu and Jiesi exchanged a look, "But what's the matter with the restricted type, aren't you the AI of this spaceship?" ”

"AI: Unrestricted artificial intelligence, I am not AI, I am just an auxiliary restricted artificial intelligence with low management authority, and I do not have high subjective motivation."

"In other words, she's just a basic helper and not 'smart.'" Jess turned her head to look at Ling Yu, "It's not strange, the real AI may be in the 'Ark'." ”

"I'll ask you about the Ark when I have time." Ling Yu nodded, "Avina, what is this area for?" ”

"This is the terminus of Commuter Transit Line 17, the cargo and resource dock area, from where you can take a commuter bus to the 90-degree loop of the spacecraft." Avina's voice exuded the stiffness and numbness of a machine, even though she was a girl.

"90-degree ring?"

"The spacecraft is divided into four rings, divided by circumferential angles, and the 90-degree ring is the area from 90 degrees to 180 degrees."

In other words, the ship is divided into four zones according to its angle. Ling Yu nodded, supported his chin with his hand, and turned his head to look at Jiesi, "What do you think?" ”

"Let's go to the Sixth Bridge first." Jesse thought for a moment, "It's best to get a map of this area first." ”

"I need to go to the Sixth Bridge...... Commuter car? Ling Yu nodded, and gave the order to Avina in a tone of uncertainty.

"Okay, it's being dispatched...... If an error in the genetic sequence has been detected and you do not have access to the Sixth Bridge, please re-verify your identity and contact the Sixth Bridge using the communication device next to it if you have any other questions. Avina's body suddenly flashed with a yellow light, and then gave a negative answer that surprised Ling Yu.

"Uh...... How so, am I not the first mate? Why doesn't even have access to the sixth bridge? Ling Yu rubbed his chin and turned his head to look, but he didn't find the "communication device" in Avina's mouth.

In fact, Ling Yu was mentally prepared, no matter what reason Avina gave - there was no electricity, the car broke down, and the road was blocked, he was not surprised, but this was indeed an answer he didn't expect.

"Yes, Mr. First Mate." Avina just gave such a clueless answer.

"Sure enough." Just when Ling Yu was inexplicably at a loss, Jiesi, who was holding her chin and thinking, suddenly spoke up.

"Do you know what's going on?" Ling Yu turned his head, but Jiesi didn't answer, just pressed her right hand on the panel where Ling Yu had just performed the genetic test.

"Identification error, if you use a robotic arm, use a natural arm for genetic testing, if you don't have a natural arm, use a genetic permission card."

This time, Avina gave an answer that made Ling Yu seem to realize something, but when he turned his head, he only saw Jesse waving at him.

"Boss, let's go to the living area first."

"I'm going to the living quarters, is that enough?" Ling Yu looked at Jeunsy and wanted to ask something, but swallowed back the words and turned to Avina to give an order.

"Okay, the order has been received, the condition of the vehicle is being checked...... The test has been completed, and the response from car No. 13 has been received...... Transfer......

Ling Yu looked at Jiesi, the girl seemed to be pondering something, and Ling Yu didn't bother.

Soon, a black triangular car drove up and stopped at the platform.

"Prehistoric civilizations seem to have liked the shape of triangles." Ling Yu looked at the "commuter car" in front of him and deliberately made a joke.

"Uh-huh...... Jesse nodded absentmindedly, "Anyway, let's go to the living quarters first, I'll explain the rest to you on the way." ”

=====================

When I got up in the morning, I saw that the three rivers had passed......

Wha www.biquge.info ha

Next week's 21 watch, three watches a day, starting from January 19th for seven days!

If the results are good, it may be extended to 10 days!

By the way, this book is obviously not a 3Q structure (300 protagonists, 3,000 hanging, 30,000 cool points), all the design, plot, emotional cultivation, and details that seem inconsequential now are all [essential] foreshadowing for the future.

I won't explain it in the future, but for the last time, thank you for your support!
