One hundred and eighty meters underwater, you can't see anything without relying on a strong searchlight. Looking up at the top, it was pitch black, and Lucifer remembered that he had looked down from the observation deck on the third floor of the Eiffel Tower, and he could see the palm-sized bus, which was nearly 100 meters lower, but the Ohio, which was more than 200 meters away, was no longer visible.

The two-meter-high black iron box, square, has a dial with different scales underneath, and three seconds hands-like hands are fixed in the center of the dial, painted with a thin blue glow. The speed of the hands varies, sometimes fast and sometimes slow, with subtle waves blowing downward.

"The blue light on the surface is Professor Kareven's meditative consciousness, relying on this membrane magnetic needle to rotate all the time, so that the iron box does not sink to the bottom of the sea. On the display in front of Oguyedu was a black iron box that glowed with a faint blue light.

When Lucifer approached, he saw gears embedded in the iron wall, gold threads floating in the water, and those were the internal parts of the magnetic needle, creating a large gap. "It's not a sealed box at all, and if it weren't for the membrane on the outside, the people inside would have drowned in the influx of seawater before the box sank to the bottom of the sea." ”

"Do you think we can bring it up before the sea fills the box?" asked Oguyedu.

"No, you can't. Lucifer gave a direct guess, and then made a quick circle around the box, allowing them to visualize how poorly sealed the box was. "The surface area of the whole box is about 16 square meters, and a third of it leaks, and if you don't have enough water, you can't lift the box within five minutes. But that was impossible, and given the weight of the box and the resistance of the seawater, it would take at least twenty minutes to adjust the speed of the elevator to retract the chains to the maximum. ”

Oguyedu groaned, unconscious meditation is a very shaky existence, which undoubtedly hints at more than one level of difficulty of the mission, once the blue light is accidentally destroyed during the mission, before they can retract the iron box, Natalia will be drowned in the icy sea, and the rescue operation will be a complete failure.

"I'll give you another piece of bad news. Lucifer said quietly.

Oguyedu was drawing up a rescue plan with the command center, and when he heard Lucifer's voice, Oguyedu had an ominous premonition in his heart, and he asked carefully, "What bad news", as if he was afraid that his words would accidentally break the protective film.

"We always think about drowning and suffocation, but we keep missing the important point. ”

"What...... What?"

"Temperature. Lucifer's tone was solemn, "I looked at the weather forecast when I came, the average temperature in Nuuk, the capital of Greenland, is five degrees, and the temperature is minus three degrees, and the sea water should be more than ten degrees below zero, not to mention that this is an iron box, and it should have been cold to the bone after such a long time." According to the images from the Eye of Providence, the girl inside appears to be wearing only a skirt and a coat. ”

Oguye was stunned, Lucifer was a little wrong, the temperature of the Arctic Circle affected by the Arctic Ocean will not be lower than minus two degrees, but the maximum temperature will still not be higher than zero, and if you don't take in energy for a long time, you will destroy your own thermoregulation system, and the heat dissipation will be greater than the heat production, and you will freeze to death.

"That's terrible!" Oguyedu frowned, "Second diver ready to dive." ”

Lucifer raised an eyebrow, "Already have a rescue plan in place?"

"Can't hesitate any longer, time is ticking. Oguyedu thought for a moment and added, "If you are careful enough, you should be able to succeed." ”

"Understood. Lucifer shook the camera up and down, "It won't break the protective film." ”

……

Lucifer had been looking around the iron box for the time Asa had been coming down, he reached out and touched it, and the blue light spread out like water streaks, as if it could be pierced with a finger, but in fact, Lucifer increased his strength, and his hand was almost put into the iron box through the gap between the gears, and the light as thin as light gauze was not torn as he imagined.

He withdrew his hand and stopped tempting, looking quite sturdy, but if it really broke suddenly, it was too late to cry.

He swam down to see the structure of the propeller, three ordinary pointers, not even of the same length, set together and fixed with the backbone of a perpetual motion machine. He looked carefully, the perpetual motion machine was not rotating, and this weird propeller was indeed working without power.

Lucifer had studied Perpetual mechanics, and at that time he was the head of the first section of the equipment department, that is, the head of the headquarters, Oguyedu, personally taught.

Perpetual mechanics has always been known for its obscurity in the Donnas, and the failure rate is as high as 40% every semester, except for students who are interested in the equipment department, few people choose to take this course. Lucifer is not interested in the Armament Department, and as a prince, he is not as passionate about machines as other boys. But he still chose this course that was difficult for him and he didn't like, because the girl she liked was from the equipment department, and she chose this course.

Perpetual mechanics is really difficult, and it feels like he has strayed into a Chinese classroom - he has always specialized in oriental culture, and once even went to a Chinese university to experience the class, and that class was about ancient history, the dispute between Chu and Han. Lucifer listened in a fog, and only remembered the man who was regarded as a hero - Xiang Yu throughout the class. It's just that he still doesn't understand why Xiang Yu refuses to cross Jiangdong.

Lucifer could rarely memorize the basic names of machines, and he barely passed the final exam with the help of his classmates, and he basically forgot the content of the class so far, but at this moment he suddenly remembered the kind of ability that the professor inadvertently mentioned in a certain class - meditation.

Meditation is a very special ability to control machinery. In an old Chinese saying, "man and sword are one", but this "sword" is not just a sword, it can be any metal material, even if it is just a small screw.

Professor Oguyedu said that if a meditator is attacked in a meditative state, his body will be injured, he will bleed or even die, and the meditator will not be aware of it. Once the physical body dies and the meditator cannot wake up from the meditative state, his mind will be trapped forever in the attached machine, feeling and thinking, but unable to do anything, and the machine will become a real soul.

He cast a gap and looked inside, and the faint light shone on the white girl, who was asleep, and even though the light was dim, Lucifer could still see the tears in the corners of her eyes, and her eyelashes, long and dense. The girl held a green coat in her arms, curled up in the far corner of the box, and sometimes she would suddenly grab the clothes in her hands, and her little body trembled slightly, as if she had some terrible dream.

The blue halo was faintly sprinkled on the girl's body, and the blue light was the presence of meditation. Lucifer was curious, according to Professor Oguyedu, Professor Carrivan should still have senses now, and I wonder if Professor can feel the cold, biting, and desperate of the bottom of the sea now. And can you understand the helplessness, fear and loneliness of the little girl's dream?
