Li Liang was stunned for a moment: "What do you mean?"
"The earliest record was more than 900 years ago," Cain looked confused. "This submarine has been going in circles in the depths of the sea since it was launched into the sea."
"What?"
"Really going in circles, like looking for something."
"Then what?"
"Sometimes it accelerates, sometimes it stays, and then it continues to circle, and it keeps going and going, until the last captain shut down the system three hundred years ago and everyone left here."
Li Liang frowned and said, "Continue."
This kind of navigation route is actually not difficult to understand. It seems to be a patrol. Therefore, there must be something more special that makes Cain speculate that the record has been modified.
Cain said quietly: "From the records, the Defender is simply sailing, or like patrolling."
"Yes," Li Liang nodded, waiting to hear what was going on, but found that Cain did not continue, but stared at him.
He asked subconsciously: "What's wrong?"
"Don't you think it's strange?" Cain tilted his head and smiled, "Why did Xi'an build such a large submarine for patrolling?"
This sentence suddenly woke up Li Liang.
Xi'an owns the whole world directly or indirectly, but throughout the world, it has always adhered to pragmatism.
For example, recyclable garbage from the upper city will be discharged to the lower city for recycling, and the canopy chooses a screen instead of a more energy-consuming holographic projection to simulate the sky.
It’s just that the technological level of Xiacheng District has been suppressed. The performance iteration of the garrison robot army is also very slow. It is said that armed drones, armed robots, and centurion robots were already at the current level a long time ago.
Not to mention the social system in the lower city, the chaotic New Order Joint Conference, etc.
Including the exploration of the spiritual world, once it proves that something is impossible, give up decisively.
Xi'an is like a cold machine, strictly controlling all costs.
Building the Defender must be expensive, and using it just for patrolling is definitely not Xian's style.
"So, I think someone deleted some key records," Cain speculated, "obscuring the Defiant's true purpose."
Li Liang looked solemn, vaguely feeling that there was an answer lingering in his mind, but he couldn't grasp it.
Feeling a little irritated for no reason, he asked casually while thinking, "How did Mayfly find this submarine?"
"Do you still remember, at Zhenjie Fort, you asked me if the previous lords had ever been to the upper city area."
"Well, you said that the second-generation Lord went there and committed suicide when he came back."
"Before committing suicide, he led Mayfly to find the submarine." Cain jumped onto the base of a remaining hoisting equipment. "He didn't tell others how he did it, but I estimate that he probably got the defender in Uptown. No.’s location.”
"It's possible," Li Liang thought for a while, "By the way, are there any areas that you can't enter?"
"Ha," Cain squatted on the high metal shelf, "you finally thought about it. In fact, I can't get in from the first to the fifth floor."
Li Liang nodded.
now it's right.
There must be a core area that only Xi'an people can enter, which is more important than the general control hall.
Cain stared at Li Liang's expression, raised the corner of his mouth, turned over and jumped off the base, put his feet on his neck and said, "How about you, do you want to open my eyes with me?"
"It seems that Mesai is overthinking. You don't need to comfort her," Li Liang said without squinting and pushed her forehead away with his fingers.
"You need it, why don't you need it," Cain said seriously, "When will you be comforted? Now?"
"That's almost it. Hurry up and show you the way."
"Not interesting."
Cain sighed dramatically.
ten minutes later.
The two of them followed the remaining tracks on the ground and came to two huge and heavy metal doors. There were many slide rails under their feet that penetrated into the gaps under the doors, like the entrance to a closed train tunnel.
Li Liang looked at the "platform" on one side, and there was a small door there... When he and Cain first met, he entered the elevator room through that small door, and took the elevator to the main control hall.
Unexpectedly, the entrance to the core area was so close.
"This..." Li Liang raised his head and looked at it, "How do you open the door?"
Cain tapped his chin: "There, there's a doorknob."
Li Liang walked closer and saw a small handle that could only be held by an adult with one hand.
"..."
A giant metal door more than ten meters high with such a small handle, how can you play with it?
However, there is indeed no other verifiable area or controller on the giant black door.
Just this funny little handle.
He had no choice but to reach out, hold the handle, and pull gently.
next moment.
The giant door quietly opened a crack.
A stream of hot air surged out, making a whirring sound.
Li Liang immediately smelled a strong metallic smell.
"What does it smell like?" Cain poked his head behind him, "What's inside?"
The thickness of the giant door is extremely exaggerated, so the two doors are connected at an oblique angle, leaving a gap so that no one can see inside.
Li Liang covered his mouth and nose with his sleeves and opened the door a little bit. He felt that the resistance was moderate and there should be a power-assisted device at the door axis.
Soon, the door was opened enough to allow you to enter sideways. There seemed to be something flashing orange-red light behind the door. Since the door gap was beveled, only light and shadow could be seen.
The door was opened bit by bit, and the light coming out became stronger.
Until finally, the scene inside is revealed.
Li Liang and Cain stood at the door, stunned.
Inside the door is an empty platform, and in the far distance is a transparent column with a diameter of tens of meters, with dazzling energy surging inside, like the surface of the burning sun.
Braving the scalding strong wind, the two passed through the giant door and walked onto the platform. After more than ten minutes, they reached the edge of the platform, holding on to the guardrail and looking down.
This is a loft space, with five floors of platforms protruding out step by step, surrounding a transparent column standing in the center.
The sixth floor platform they were currently on was the largest in area, with many criss-crossing tracks that penetrated into other giant doors around it.
The platform below is indented step by step, resulting in the entire space taking on the shape of an inverted funnel.
At the bottom, there is an extremely complex group of equipment surrounding the cylinder, with tangled pipelines and lines, like an enlarged version of the chip surface.
The orange light emitted by the boiling energy in the transparent cylinder reflected on Li Liang's face, and a layer of fine beads of sweat appeared on his forehead.
this moment.
He finally caught the thought in his mind.
A giant submarine cruising in the deep sea, a large number of cleared areas, engines and equipment that can still operate normally after hundreds of years, plus the world map in the weapons base underground in Zhongjing...
It is possible that the Defiant was once used as an "ark", where the Xi'an... hid when an all-destroying nuclear war broke out.
"Cain," Li Liang's voice trembled slightly, "When did the nuclear war that destroyed the world happen?"
