It's another evening, the sky is gray, and the night belonging to the far north seems to be coming.

The orange sun hung on the horizon in the distance, the snow-colored ice fields in the distance reflected the dim light, the cold wind howled, and the white ice crystals like sand and dust fluttered on the earth, and the whole world was filled with a sense of death and gloom.

However, with the passage of time, the sunset on the horizon did not completely set.

It moves slowly on the horizon, as if it is translating, and the trajectory of the movement is almost parallel to the horizon, and the angle of change is very small, as if it will never fall.

This spectacle can only be seen in the polar regions of the planet.

People who have lived here for a long time understand that they will experience this for many months to come.

This is the polar day.

There is no night, only light, and the sun shines twenty-four hours a day.

At this moment, the extreme north region is experiencing a long polar day for six months of the year, while the extreme south region is experiencing a long polar night.

At this moment, on the thick ice sheet in the far north, there was a slight noise in a certain area.

"Brush-brush-brush-"

If you listen closely, the noise is coming from below the ice sheet, very coherently, with some rustling sound, as if some animal is cutting through the ice below, trying to get on top of it.

If the polar expedition personnel heard the sound here, they would be very surprised, because the ice here is already fifty or sixty meters thick, what kind of creatures will move in such ice?

Could it be the legendary Arctic monster?

More than ten minutes later, the strange sound approached the ground, getting closer and closer.

After a few more minutes, only a click was heard, and a sharp metal shard spun rapidly, piercing through the ice and flying into the air with a whirl.

In the vast ice field, this small piece of metal is inconspicuous.

The hole it penetrates through the ice is only about a centimeter in diameter, and it can be buried by just waiting for the cold wind to blow a few fine ice crystals.

But, soon, a small mechanical reptile crawled out of the hole, the size of a coin.

After this little reptile came out, its wings spread, rose with the wind, getting higher and higher, its body seemed to have no weight, and it flew hundreds of meters into the air in just a few minutes, overlooking the world below.

[No signs of activity of the mechanical creatures have been found, and an area of 500 meters around is being searched]

A message was passed to Su Xia, and with it, the vision shared by the mechanical crawler.

At this moment, Su Xia is under the ice.

His face was serious, his brows were furrowed, and his mind was highly concentrated, and he kept sending more nanobots out to explore the way.

This area is exactly where he chose to go ashore.

Contrary to all speculations from the outside world, Su Xia did not choose an island, nor did he choose the edge of a continent, but came to the thick arctic ice, forcibly penetrated the ice, and created a place for himself to go ashore.

The extreme northern ice layer of this world, which is much thicker than that of the earth, has caused Su Xia a lot of trouble.

"Unexpectedly, it took more than ten minutes just to punch a hole the size of a coin." Su Xia sighed, the ice here was harder than he had imagined, and he had expended a lot of psionic energy to make a passage.

"Well, am I right? There are no robots out there! The big whale said proudly.

This area was actually chosen by him for Su Xia.

Prior to this, he unleashed his spiritual fluctuations, and as an overlord, he drove a large number of sea creatures, and it took him two or three days to choose this location for Su Xia.

In order to ensure the safety of the sea, he even drove some creatures such as arctic foxes and arctic wolves on land to this area as a reconnaissance force at any cost.

You know, most of these creatures live in the Arctic tundra region, and rarely come to such inland areas.

"It's true that there are no mechs, thank you." Susha expressed his gratitude to the big whale.

"Thank you, they're all fellow travelers anyway!" The big whale said casually.

At this moment, Su Xia had already put away the big submarine and took the small submarine for sightseeing, suspended under the ice.

He looked up and could see an uneven layer of pale blue ice through the sturdy sightseeing glass, like the sky in the underwater world, as if he could touch it with his hand, with a bit of mystery, making people feel like they were in another world.

The big whale was suspended next to Su Xia, its huge body of more than three hundred meters, in the dark and cold water, it was impossible to see its head at all, only a part of his body.

"You know how to get around when you leave here, right?" He asked Susha.

"Yes, I have the map." Su Xia nodded.

"Once you're gone, you don't know when you'll come back, and the next time we meet, it's probably many years later." The big whale sighed, although he didn't get along with Su Xia for a long time, but when he parted, he was quite reluctant, hoping that Su Xia would stay for a while and go with him to explore those mysterious areas of the Extreme North Sea.

In the years of his long life, he had never made a human friend.

For a long-lived sea monster like him, friends are a precious creature.

He had lived so long that he had forgotten how many years he had lived, and the friends he had made when he was young were now long dead, some of them of old age, some of them fighting sharks, and some of them being hunted by humans.

It was so long that he had forgotten what his former friends looked like.

Year after year, day after day of boring life, he can barely be regarded as his friends, that is, those sea monsters who are also aliens.

"Don't worry, I value my time." Su Xia smiled, "It's not enough for many years, at most half a year will come to you." ”

"Half a year?"

The big whale didn't believe it and asked suspiciously: "In half a year, can you defeat those robots?" ”

"Half a year is enough, the war is imminent, and the final storm is about to start." Su Xia said: "I go back this time, it won't be long before there will be a race war on the land, and it may spread to the sea at that time, so you have to prepare in advance." ”

"So fast?"

"Hmm...... In fact, I smelled war before I went to the bottom of the sea. ”

Su Xia's eyes were deep, and he looked up at the bottom of the ice and thought of a lot.

For the automaton, the undead are an uncontrollable factor after all.

They will not allow any uncontrollable factors to grow, and the best option is to strangle them in the cradle.

At the same time, the wreckage of alien spacecraft around the world is also surfacing one by one, and the next war may also involve the scramble for these wreckage.

The final winner will definitely be able to break out of this planet, become the representative of civilization on this planet, and lead everyone into the interstellar era.

As Su Xia pondered, more and more information was passed back.

[No signs of activity of the mechanical creatures, and an area of 2,000 meters is being searched]

[No mechanical ...... found]

【……】

More than half of the nanobots were sent out by him.

For the sake of safety, the little robots no longer maintain the form of reptiles, but scatter one after another, activate the environment to become invisible, and turn into shining white ice crystals, like sand and dust in the desert, gently fluttering in this white world with the wind.

They are mixed with ordinary ice crystals, and there is no anomaly at all, no different from other ice crystals.

In addition to them, there are also those arctic foxes and arctic wolves driven by the big whale with their spiritual power.

Soon, the area within a radius of about ten kilometers was fully explored, and there was a dead silence, with almost no trace of life except for themselves.

"It should be safe."

Su Xia glanced at the time, and then his heart moved, releasing dozens of tiny metal fragments.

Under his control, the metal shards began to spin rapidly, like sharp blades that never stop, and began to cut through thick layers of ice.

This time, he wanted not just a hole, the size of a coin, but a passage that could accommodate his own entry and exit.

"Brush-brush-brush-"

The cutting speed was fast, but in a few moments, a round hole with a diameter of more than forty centimeters gradually took shape.

As the cutting progressed, countless fine ice crystal particles were scraped off, like fluttering white catkins in the water, clumps, and finally dissolved into the seawater, gradually disappearing.

"You're pretty good." The big whale was a little envious, "If you go to work as a construction worker, you can build an iron tower in one day, and one person can get hundreds of people's wages...... When you go to the vegetable market and sell watermelons, you don't have to put magnets under the weighing pan......"

"Do you know how to put magnets?" Su Xia was surprised.

"I've lived for hundreds of years, and I still know these things."

“……”

During the communication between the two, time passed slowly, and the hole was dug deeper and deeper.

At the same time, Su Xia also took a serious look at the outside far north world through the shared vision of nanorobots.

This was the first time he had come to such an extremely cold world, and he naturally had a lot of curiosity in his heart.

"I heard that in the far north, there is a period of time every year when you can see the appearance of the aurora, but unfortunately it is not the time yet." Su Xia was a little regretful, there were many things that he didn't have a chance to see on the other side of the earth, so he could only pin his hopes on the game, hoping that it could be realized in the game.

"There's nothing to look at, I'm tired of watching it." The big whale spoke casually and didn't care at all.

"Of course you're tired of watching ......"

Su Xia pursed her lips, too lazy to bother with the big whale about these questions.

Under his careful control, the metal fragments in the hole spun rapidly, cutting and scraping the ice, and had already reached a depth of three meters.

"Next, there's fifty-four meters of thickness." Su Xia took out a few psionic replenishment potions and replenished her energy.

The energy is consumed too quickly, and if it is not replenished, the blue bar will bottom out.

It's a very boring process, very tedious, repeated, cut over and over again.

"It's a pity that the ice is too thick, otherwise you can experience the feeling of a submarine breaking the ice." Su Xia often sees the shocking picture of the nuclear submarine breaking the ice in various military videos, and has always wanted to give it a try, but now he has no chance.

Many ideas will not be realized until after the war.

Time passed slowly, and the cold wind above the ice never stopped, as if it had been the case for thousands of years.

In this cold and dead place, time seems to have lost its meaning, everything will not change much, and the world will be white.

I don't know how long it took......

Finally, with a click, a thin piece of ice shattered, and more than a dozen tiny metal fragments broke through the ice.

The nearly sixty-meter-thick layer of ice, under Su Xia's unremitting cutting, was carved out of a vertical passage large enough for normal people to pass through.

"It's time......"

Su Xia let out a breath, and sent a lot of it all over her body, and a feeling of exhaustion surged up from the bottom of her heart.

Controlling metal for such a long time consumed not only the energy in his body, but also his mind, after all, he had to stay focused at all times.

Above him, at the mouth of the passage, the sea rippled, and a bright light appeared, as if it was the entrance to another world.

The sea and the sea are indeed two different worlds.

"It's time for me to go." Su Xia turned his head to look at the big whale, and his voice was flat.

"Good...... Take care all the way! ”

The big whale didn't say anything to stay, he knew that Su Xia had a heavy task, so he just waved his tail lightly and rolled up a gentle stream of water, which was regarded as a farewell for Su Xia.

Su Xia smiled lightly and said, "You also take care." ”

After that, he pressed the submarine's exit button, and seawater instantly poured into the submarine, balancing the internal and external pressure, and the submarine's hatch slowly opened.

The chill of the sea instantly enveloped Su Xia, eroding his skin, making him feel like pins and needles.

Su Xia swam out of the submarine, waved his hand, then put away the submarine and swam to the entrance of the passage.

Looking up, the sky was white, and the sunlight was a little harsh.

Su Xia's eyes narrowed slightly, and he didn't hesitate for too long, and rushed up, rushing out of the seawater world along the smooth and icy ice passage, and returning to the land he had been away from for a long time.

With a few clicks, the sea water on his body instantly turned into ice, turned into ice slag, and fell to the ground.

Whew!

The cold wind was biting, howling by, like a knife cutting through his wet body.

The temperature of dozens of degrees below zero instantly made a thin layer of ice on his clothes, and the skin stained with sea water instantly lost consciousness and was numb from the cold.

"Whew...... This temperature ......"

Su Xiaha let out a mouthful of white mist, the whole person trembled in the cold wind, and his whole body was almost unconscious, and he subconsciously rubbed his arm, and the ice crystal particles on his arm fell one after another.

In just over ten seconds, a thick layer of frost and ice appeared on his hair and eyebrows.

The Far North is a forbidden area for life.

As far as the eye can see, the whole world is only the white of ice crystals, ice and snow, and thousands of miles of ice.

Su Xia immediately took out some blood-invigorating elixirs, poured them into herself, and then wrapped herself in several layers of thick coats, which was barely comfortable.

"From here, all the way south, the ice will gradually thin, then it will pass the Beiyang Bay, and after the Beiyang Bay, it will be the Scannes Peninsula, through the peninsula area, to the southeast, and then across the Mountains of your and into the Great Plains......"

Su Xia calculated the distance, and this road spanned almost the entire northern hemisphere from north to south, from high latitudes to low latitudes.

Pure flying allows him to save a lot of time, and the speed is much faster than at the bottom of the sea.

When Su Xia was looking at the map, the big whale under the ice suddenly moved, setting off a wave of fluctuations.

The big whale passed through the ice, transmitting a spiritual power and asked Su Xia, "Why don't you move?" Isn't it going to be frozen? ”

"No, it's just calculating the route." Su Xia laughed.

"Oh, I thought you were stiff."

"Not really."

"Is the route settled?"

"Alright."

Su Xia looked relaxed, put away the system map, and the specific route had been memorized.

He looked into the distance, his body slowly rising, then looked down, smiled at the big whale under the ice, and said the last word.

"Gone!"
