Four months have passed since the disappearance of the E562 freighter, as no signs have been detected by sonar. Sino-Ocean International Transport Group announced that the cargo ship had been killed and all search and rescue efforts were stopped.

March 15, 2021

The vast island of Greenland, covered with snow and ice, blows in the wind, and snowflakes are raised like quicksand. There are all kinds of footprints on the ground, as if they have been turned into ice fossils. In the distance, on the surface of the Arctic Ocean, icebergs fall from time to time to break through the water, and pieces float on the surface of the water like broken floors. A humpback whale emerges from the ocean and spews water from its back from time to time, like a volcanic eruption, with a Y-shaped tail floating and swinging, like a flower in the water under the sunlight.

The air flow from a helicopter's blades swirls the surrounding snowflakes around, and the roar of the otherwise silent village is noisy.

Three people got off the plane.

In addition to Liu Fei, there are also Tucker's external scientific advisors: Zhou Yue and Wu Fan.

According to radio tracking, the frequency bands where those sound waves are emitted are in the western part of Greenland.

"Oh my God, the temperature here is really low," Zhou Yue said.

"But no, look at it, you see ......" At this time, Wu Fan poured the water from the thermos cup he brought with him to the ground, and it didn't take long for it to form an ice surface.

"If we still don't find it this time, Liu Fei, what do you say?" Zhou Yue looked at Liu Fei.

"This mission is not trivial, the clues found from the sea last time are extremely important, although the freight company has paid all the cost of damage, but if the mohair is not found, the whole research will be interrupted... It's not about the money!" Liu Fei's righteous reply.

"But don't you think it's too mysterious? How could it be possible to run from the Red Sea to Greenland suddenly, and what speed does that have to be?" Wu Fan on the side said.

Wu Fan is a young programmer, 25 years old, a typical otaku, who hacked the computer intranet of a 10,000-person enterprise at the age of 16.

And Zhou Yue, in her early 30s, is an extroverted female scientist specializing in biological genetics.

"Now the only clue is this band signal and this little piece of paper, let's take one step at a time." Liu Fei replied.

It is a village just 30 kilometers from the signal source, and the village is inhabited by legendary Eskimos.

Because it is the polar day, it is a tiring thing for the original long-distance flight journey.

The white snow and the sun that never sets make this place feel like it's different, everything is white and the world is back to its roots.

Wu Fan turned on the computer he was carrying, and opened his analysis data of the frequency band.

"I've been analyzing this band for a week, it's like some kind of password, and I can't hear anything on a single bar.

But when these bands are stacked every 10 minutes for a segment, the resulting number is:

29 58 33 ?31 ?07 ?50, which is a set of coordinate numbers.

"Guess where?" Wu Fan said

"?

"This is Egypt . . . Pyramid! Liu Fei said

The exact location of the coordinates is displayed on the screen.

"What must they be trying to convey? Is it just a pyramid? ”

"Who are they? What are they going to do?" Everyone was at a loss.

The model of the pyramid remains to be examined, but the source of the signal emission band in front of you is the purpose of this trip. In order to be able to investigate the disappearance of Mohair in good spirits, they rested in the hotel for two days. The next day, I began to prepare my luggage and equipment to enter the signal source. Due to the mountainous terrain and unpredictable climate in the western part of the village, the area can only be driven into the area by electric sleds led by locals. Standing on the top of the mountain and looking down, the sleigh is like a small dot on a white canvas traveling around the curve. They were enjoying the white scenery while looking at the destination shown on the GPS. After about 10 kilometers of driving, primitive Eskimo snow castles and oval-shaped white huts appeared on both sides of the road. From time to time, you can also see people entering and exiting the gate of the snow castle; On the road outside, there were people dragged home by five or six huskies, and there were people playing together. Most people here eat raw food, because the nutrients in raw food are more intact and can provide the body with high-calorie protection. Before leaving, they also tried the local whale meat and seal gall.

In an area two kilometers from their destination, a group of people are performing some kind of ritual. Thirty Eskimos sat together, pale and closed on the ground, sitting around a fire, in a hexagonal shape, waiting for the masked leader to recite a few incantations, and then all of them went into a meditative state, reciting incantations together, as if asking for something...... After about half an hour of the ceremony, everyone put on their bearskin costumes and left.

The trio soon found themselves near the source, and the noise on the computer screen grew louder and louder.

Halfway up the mountain, there was nothing but snow around, and the air was empty except for cold and tension.

The three of them used their instruments to scout as they walked, and they scanned the surroundings to see as if they were in front of their heels.

"Will it be underground?" Wu Fan said

"How so? This is a signal transmitting device, and according to the strength of the signal source, this device will not be invisible"

"Let's go separately and look for it, we must pay attention to safety and keep communicating at all times," Liu Fei said

"Good" Wu Fan and Zhou Yue replied

The three men then looked in different directions for the source of the signal within a mile of the surrounding area.

Zhou Yue looked at the compass in his hand and walked a distance to the north, three arctic foxes came out from the side of the road, and when they saw someone's movement, the fox immediately avoided it. It's cold, but it's still alive, with 900 species of flowering plants and thousands of caribous, musk oxen, and arctic rabbits. 1/6 of all birds in the Northern Hemisphere breed here. As she walked, Zhou Yue collected the hair left by some plants and animals on the road as a specimen for study.

At the other end, Wu Fan went to the downhill of the mountain, looking at the instrument in his hand while walking, the sound waves were still being sent, but sometimes without interruption...

At this moment, there was a roar from the snow-capped mountains in the distance, and the sound was deafening, and everyone covered their ears.

"Oh my God, it's an avalanche!" Everyone is aware

Seeing such a scene, everyone instinctively ran up to the top of the mountain. However, the luggage was too heavy and caused him to move slowly, so Liu Fei decided to abandon some of it and escape. Snow pours down from the top of the mountain like a waterfall, so everywhere you pass is covered with a thick layer.

By the time they reached the top of the mountain, the avalanche on the opposite side had closed the road and the valley was calm.

"We're stuck," Mr. Liu said
