Observation station on the shallow margin of the continental shelf in the eastern part of the Oji-Sato Peninsula.

Scarlet has two hours on duty today.

Today is not the time to change the stationing robot under the sea, so the work is relatively idle, just let the hunters who brought it to conduct a routine physical examination of the stationing robot, and she herself sits in front of the monitoring table to look at the recent data.

The three-level observation post is manned by a mixture of humans and machines, and non-human personnel come down every two days during the normal day and work on the seabed for two hours at a time. At first, they were in a class of two, and after getting used to it, now they are in a class of one person.

Both Chief Ke and Teacher Cha call these two hours an absolute retreat.

Scarlet thought it was okay, sometimes she would bring some work down to think, sometimes she would sit idle and look at the sea outside, and two hours would pass quickly.

At low tide, there is no swelling in the sea, and outside the dome of the observation station, the current is very light and gentle against the isolation wall, and you have to get used to this absolute silence before you can hear the slightest ripple.

At this time, it is the winter stipulated by the unification of the pan-continent, but on the continental shelf cliffs of the Pampong Sea, those fish can't wait to prepare for the next lively season.

Some of them inhabit the vast sloping seagrass at the end of the continental shelf, and the midday sun shines through the sea, casting the last faint light in the seagrass, and they swim briskly at the interface between light and darkness.

Others hide in a dark stone nest beneath the cliffs of the continental shelf, waiting to be hunted.

Scarlet stares at a one-eyed fish labeled as Non-An'an 18. It flicked its tail leisurely across the surveillance screen.

Well, it's alive.

It's not easy to survive a winter. She pondered.

"Non-security" is the mark of the Department of Security of the Ministry of Non-Human Affairs. It is not a safe species under the Ministry of Human Security.

Usually, if it is not for the discovery of new species, the safety department of Scarlet will not be as keen on marking marine creatures as Chief Ke and Teacher Cha, Chief Ke and Teacher Cha need to track and study species, and they like to mark the fish, birds and even sea vegetables they encounter all day long.

Generally, the scarlet only marks those highly dangerous species that attack humans, and mark them as "non-safe" plus numbers.

Fortunately, there are almost no creatures that need to be on guard in the area under the jurisdiction of the shallow continental shelf observation station in Benpanghai.

Her non-An'an series is currently ranked eighteenth, and it is all marked casually when she is on duty at the Shallow Edge Observatory in order to pass the time.

Fei An'an 18 was spawned by his parents in Fuya Bay last autumn, grew up on his own, and has been eating planktonic wild food, little by little to the end of the continental shelf.

It has been alone in this area for two months, and if it can stay until the spring tide of the Benpang Sea comes, Chief Ke said that it can continue to swim to the far sea with the receding tide, perhaps bypassing the center of the sea on the back and swimming to the other side of the pan-continent.

Fei An'an 18 once again crossed the monitoring screen, and it seems that it is very diligent today and has started to hunt. It can only be regarded as medium and large, at most it circles around the upper part of the cliff at the end of the continental shelf, and does not dare to dive down.

And it's right. At the foot of the cliff, twenty or thirty meters away, a group of Lema fish from the open sea swam here three days ago and were marked by Chief Ke. They are not ready to swim up the slope of the continental shelf into Fuya Bay. Before the spring tide came, Chief Ke said that they would most likely wander around this cliff as well.

Fei An'an 18 turned back from the top of the cliff, and its lungs were not yet able to bear it into deeper, darker places. When it folded back, Scarlet prepared it to swipe across the monitor screen for the third time. Because it almost treats the Observatory as a boulder, every time it explores the cliff, as long as it is not chased by a big fish, it does not forget to wipe its young scales across the outer wall of the Observatory, and then swim away with its head and tail.

Sure enough, it did so, and then, it swam out of the surveillance screen.

Of course, it can also be monitored over long distances to see if it is successfully feeding in the seagrass areas of the continental shelf slopes.

She didn't do that.

Chief Ke's "non-learning" marker creature and Teacher Cha's "non-plant" marker seaweed need her help to count the remainder.

In addition, the 27th operation team of the Engineering Support Department also needs her to follow up on the situational situation.

If one day, Fei An'an 18 appears on the western coast of the Pan Continent, such as Lu Qi District, she can ask Shang Tan'an to help catch it and directly let it fly over the Pan Continent and return to Ben Pang Hai. She was worried.

Yu Bai stood in front of a dark curtain. He felt like a curtain.

Otherwise, it is difficult to explain such a long, wide, and flat piece of black shadow.

His heart was beating violently, as if he heard a loud sound drumming, but in reality nothing was heard.

He took a deep breath and took a step with his feet up. He wanted to see a little more clearly, even to see what was behind the curtain.

There is only forward, there is no reason to go backward.

"This is the beginning of the Kaderyo Belt." A clear voice rang out.

It was the sound that was actually received by his ears.

Yu Bai immediately looked to the left and right, but there was no one beside him, only the sea water surrounded him.

This is the situation, the sea is as omnipresent as air, as light as air, and does not hinder walking and breathing at all, but all you see is darkness.

"I'm not here." The voice rang out again, as if she had seen through his actions.

“…… Can I talk to you? Yu Bai froze.

"Yes. But don't go any further. ”

"Why?" Yu Bai subconsciously looked back at the huge curtain.

"You're going to get swept up in it, and the experience isn't going to be too good."

The sound is like attached to Yu Bai's ear, because there is no concrete voice person, the characteristics of the voice are heard extraordinarily, it is a feeling that makes people calm and have to focus, but now there seems to be some trouble in it, "We have done a very realistic job here." ”

"What you see now is the Zilian Mountain Waterfall," the voice continued, "The Xiangyang Waterfall east of the Zilian Mountain Range in the Yanshen Mountains at the bottom of the Sea Nineteen Districts of the Sea Eighteen Regions originates from the Ollie Ice Sea in the Seventeenth District of the Sea further north, and is a cold overflow waterfall. ”

"This cold overflow forms a faulty inversion layer in the middle of the depth of the Benpang Sea, the Cardel Yo Belt. You've seen it, our Flying Flower can see deep water waves as it crosses. ”

“…… Here's where it started? Yu Bai asked for a while.

"The beginning of the Kaderyo Belt." The voice corrected seriously, "If you go back to the cause, I have already said it, in the Ollie Ice Sea. Of course, the cold current of the Ollie Ice Sea also has its own causes, so ......"

There was a hint of a relaxed smile in his voice, and Yu Bai felt that he might have misheard. "Cause and effect are interlinked, and if you continue to trace back, you may have to detach yourself from the ocean itself, the continent itself, and look up to the sky. The planets around us that orbit together, the Joan Tree System, and even our Union home...... It was decided that this was Rawang, and Rawang was like this. ”

Yu Bai subconsciously raised his head slightly, and the darkness of the curtain and the darkness above his head seemed to be bridged at a higher place, like a chaotic world.

But the image in his mind couldn't help but penetrate the sea with the prompts of the voice.

At this time, Brother Qiong is the hottest time of the day. He said in his heart.

As you can imagine, the sun sprinkled like crystals on the surface of the sea, like shining flowing water, on the most cutting-edge stones of the Shrike Black Cliff Observatory, and a team of robots had gathered around her, flying from the stones into the sky and the ocean......
