Mayumi looked up at the news on the big screen on the street, then turned to Starry Night and said, "Is this the one you said you lit up yesterday?"

"yes! Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ”

Then the news host began to broadcast another news: "According to the TPC spokesperson, the newly built Antarctic submarine base - Ice City was also officially put into use yesterday, Ice City adopts a new seawater cooling system, which can greatly reduce the temperature of Antarctic seawater, and the area of Antarctic icebergs will not be reduced from now on, and human beings will not face the problem of sea level rise." ”

"Alas, while trying to find a way to warm up the alien planet, while cooling your own planet," Starry Night couldn't help but shake his head when he saw the news, feeling really ironic: "Human beings stopped using chemical energy after the solar microwave power station promoted by Starry Night ten years ago was launched, and most of the factories that produce greenhouse gases were closed, but even now the greenhouse effect has not stopped, and even has to use technology to reduce the temperature of seawater, so as to prevent glaciers from melting, human impact on the environment is too great." ”

"Lowering the temperature of the sea?" Mayumi was stunned for a moment, then thought about the endless sea water, and looked at the starry night with some surprise: "No!"

"You think too much, it's not about cooling the whole sea water, it's just about cooling the ocean currents around Antarctica," Starry Night said and continued to walk forward: "If you don't do that, I'm afraid the entire Antarctic glacier will melt in a few years." ”

"Really?" Mayumi nodded knowingly, and then said with some wistfulness, "Underwater City, it must be beautiful." ”

"Okay, I'm going there in the afternoon, do you want to go?" Starry Night asked casually.

"Can I go too?" Mayumi's eyes lit up, and she said with some surprise: "Underwater City, I wonder if I will meet a mermaid?"

"You're thinking too much!"

"What, can't you think about what you can't see?"

Starry Night struck mercilessly: "When you get there, you'll know, the bottom of the sea there is pitch black, and you can't see anything at all." ”

"Oh, no. ”

"Didn't you learn physics quite well in middle school?" Starry Night glanced at Mayumi in surprise: "I always know the refraction of light and the wavy diffuse reflection in the water." ”

"Refraction knows, what's the back one?"

“... Nothing!"

Although Mayumi is looking forward to taking a submersible from the TPC Research Department's mid-sea base to reach the distant ice city by crossing the long undersea road as described in "20,000 Leagues Under the Sea". It's a pity that the fact is that a plane that sits in a multi-purpose airship, and then flies over the South Pole before diving headlong into the sea and heading towards the ice city, without accidents, surprises or even a little twists and turns.

The actual journey in the sea was less than 10 minutes, and Mayumi finally understood how dark the bottom of the sea was. It is completely out of sight, and the only light source is the searchlight at the front of the multi-purpose airship.

"I can't see anything," Mayumi muttered as she looked at the dark seabed with disappointment by the window, "I thought I could see a mermaid or a shipwreck." ”

Starry Night lowered his head and pulled the computer with his fingers at random, flipped through the recent operation records of Bingcheng, and said without raising his head: "I told you, there is nothing interesting at the bottom of the sea, what is really interesting is Bingcheng, you see!"

As he spoke, he switched the computer screen to the picture captured by the camera on the front of the airship, and saw that in the pitch-black seabed, there was a large group of buildings that stretched for several kilometers, and all the pipelines and buildings were all brilliantly lit, looking like stars constantly twinkling in the night sky from a distance, more like the mythical and legendary Sea Dragon Palace.

"It's so beautiful!" Mayumi has stars in both eyes, and the scene in front of her is really shocking, although the cost of the ice city is not as good as the artificial sun, but in terms of beauty, there are more than ten streets to throw the artificial sun.

"yes," Starry Night said with a smile, "when I have time to take you to see the underwater city built in the New Frontier project, it will be truly beautiful." A new translucent material supports the surface of the sea, from which you can clearly see the clear water, and sometimes you can see schools of fish. ”

"Really?" Mayumi couldn't help shaking Starry Night's arm, "Na, na, let's hold our wedding in the undersea city, it must be beautiful." ”

"Are you sure??The undersea city is still experimental and uninhabitable, I think about it, we can have a wedding there in about twenty or thirty years, and you can inform your brother that we will get married in thirty years!"

"Ahh

Just as the multi-purpose airship sailed into the ice city, the thing that fell from the universe began to change as if it had received a signal, and quietly entered the ice city from the ground. At the same time, about a light-year distance from the solar system, thousands of unigeneous spaceships exited the space jump voyage and then turned on the light-speed engine and flew towards the solar system.

In the main control room of the ice city, Starry Night is listening to the report of the director of the ice city on the operation of the submarine cooling system and the changes in the Antarctic glacier after use.

"The temperature of the Antarctic sea is currently decreasing at a rate of 3 thousandths per hour, so that it will take only four months for the Antarctic glaciers to stop melting, and then slowly begin to freeze again, until the ice cover of 30 years ago is fully restored, and the seawater cooling system will stop. ”

"Not bad!" Starry Night nodded, and glanced at Mayumi, who was sitting leisurely in front of the surveillance screen, looking at the surveillance footage all over the ice city and outside the ice city.

"Hum, hum!" Suddenly, a shrill alarm sounded in the control room, and the lights in the room suddenly went out, leaving only the emergency lights on.

The face of the director of Bingcheng changed greatly, there was no problem in the morning and no problem in the evening, but there was a problem when the superior leader was inspecting, and asked eagerly: "What's wrong?"

"The seawater cooling system has stopped," the operator said eagerly on the keyboard, "someone has hacked into the main control computer, and the ice city has been controlled by the other party." ”

"What?" Starry Night frowned, pulled up the panicked Mayumi and walked to the console: "Start the auxiliary system immediately." ”

The director looked embarrassed and said hesitantly, "The auxiliary system is not completed yet, so it is not loaded ......"

Starry Night glanced at the director, didn't say anything, just sat down and began to tap the keyboard quickly, the main control computer had fallen into the hands of the enemy, causing all the systems to lose control. So what is needed now is to alert the outside world and let them know what is going on here and deploy accordingly.

ps: In the next tomorrow's exam, I have to review well today, and I don't have time to code, so I didn't have the update at twelve o'clock tonight, and tomorrow's update will have to wait until the afternoon and evening. (To be continued.) )
