“...... The further you go into the depths of the endless ocean, the more you feel like you're stuck in a fog, even though ......there's no fog at all."

“...... The sunlight shining from the sky was pale and dim, making the surroundings faintly hazy, as if they were in another world, and it was basically impossible to communicate with the outside......"

“...... Trying to go backwards to find the starting point of this anomaly, but it is impossible to find it, and it seems to be a small, gradual process of change, from quantitative change to qualitative change, which is difficult to define accurately......"

“...... No matter how you locate yourself according to the sun, the stars, or your surroundings, you will always return to a place you passed before, which is completely different from the flight from the ground to the universe......"

In the Atomic Universe, Lucien looked intently at the information in his hand, the experience of generations of mages exploring the depths of the endless ocean, a precious treasure, just like the attempts of legendary mages and archmages to fly from the ground to orbit instead of space jumps.

According to them, starting from a certain height, the sky also gives people the feeling of being stuck in fog like the depths of the endless ocean, and because of the existence of its own atmosphere, this feeling is more real and illusory, and it is difficult to distinguish, so it will be more difficult to fly from the ground to the predetermined orbit than normal, even if the legend would rather choose space jumping, but no matter what, this flight will not spin in place, as long as it is positioned according to the stars, it will always fly out.

However, in the same way, due to the limitations of external and internal conditions, legendary magicians such as Douglas have not been able to quantitatively give the dividing point of this feeling, and it is impossible to figure out what height to start from. The observation of the ground is completely "foggy", and naturally there is no way to study the mysteries.

After the failure of this "pursuit of the sun", Douglas focused on this, pondering and trying to find a way to locate the demarcation point, and the idea seemed to hit the alchemy items with artificial intelligence, so as to eliminate all subjective interference, so there was a lot of support for Heidi's research.

Natasha wore silver-gray full-body armor and carried the Sword of Truth, and walked in with high spirits: "When are we leaving?"

Things are on track for the expansion of Rentat. The knight's blood in her veins boiled and called for battle. If Lucien wasn't out, she'd be ready to venture alone into the abyssal crevices of the Stroop Forest, where madman-like demons of chaos were better suited as they were less afraid of death after madness - the Scarlet Plains were already overrun by the Demon Monarchs of another layer of the Abyss.

And Lucien really needs a companion to explore the depths of the endless ocean this time. In order to concentrate on experimenting, recording data, and exploring the environment. Other than that. Sometimes, the Epic Knight's intuition is more effective than that of the Legendary Mage, especially when there are subtle changes in the body.

Lucien smiled and put down the information in his hand: "It seems that you have been delayed by something." Instead of me, I can go at any time. ”

It's the end of April in the year 828, and Lucien has read the information about the depths of the endless ocean several times in order to wait for Natasha to finish dealing with the current matter.

Natasha laughed dryly twice, and said "righteously and strictly": "As a queen, how can I just say go, and it happened to coincide with the most troublesome stage of Rentat's expansion, so it was delayed for a month. ”

Then, without waiting for Lucien to answer, she waved her hand "heroically": "Let's go!"

Lucien smiled and shook his head, watching her two long legs move quickly and her back straight.

............

The sky was a pure, immaculate, transparent light blue, and the sea was a rich, tumbling dark blue, and there was nothing but blue.

The wind blew uncertainly, only the undulating sea surface was showing its existence, and suddenly, in the invisible wind, two figures slowly stood out, one was wearing a black double-breasted gown, wearing a top hat of the same color, holding a silver-white pocket watch in his hand, as if looking at "the time to go to the banquet", and the other was a beautiful lady with long purple hair flying in the wind, and the silver-gray armor made her a little cold and hard.

"It's still some distance from the depths of the endless ocean, and we're flying slowly. Lucien looked up at the position of the sun, and there was a darkness in his eyes, which seemed to reflect the stars that were obscured by the sun.

Natasha understood Lucian's thoughts, since he wanted to explore the secrets of the depths of the endless ocean, he definitely couldn't teleport directly to the vicinity, who knows if the road had passed the place where the strange things began to appear quietly, so the best way to do it was to get closer from a relatively distant place.

Before she could nod, Lucien spoke again: "Remember to grasp the changes in your body, and don't let go of any small abnormal changes." ”

"Yes. She nodded slightly, a smile on her face, like a cat that had stolen fish, "I am really, favored, spoiled, and amazed ...... to be able to come in handy in your important experiments."

The idiom "flattered" has been transformed into a lingua franca by Lucian, but in order to accurately convey the meaning, the sentence structure is quite complex and surprisingly long, and Natasha, who has only heard it once, will inevitably feel jerky when repeating it.

Upon hearing her answer, Lucien burst into laughter, and it seemed that she was obsessed with her title of "lab breaker".

"Of course, this is not a laboratory. "How could Lucien let go of the opportunity to tease Natasha.

Natasha glanced at Lucien with a smirk: "Be careful that I won't cooperate with your 'experiment' in the future, anyway, I'm an experiment saboteur." ”

Lucien coughed, wondering when the "experiment" would be successful.

The two of them flew slowly on the surface of the sea, making the sea creatures that swam by look up strangely in the air, how could anyone fly slower than us?

The flight lasted for two days, and was not disturbed by any of the "jumping" sea creatures and vicious birds due to Lucian's magic.

Suddenly, Natasha stopped suddenly, looked up at the silver moon and sparse stars in the sky a little strangely, and said uncertainly, "Seems to be a little heavier?"

The gentle smile on Lucian's face immediately retracted, and he took out a small and delicate metal hut directly from the storage bag.

Magic fluctuations were generated, and the metal hut became bigger and bigger, turning into a laboratory with relatively complete facilities in mid-air, and Lucien stretched out his hands and ten fingers flying, playing the piano to manipulate different magic arrays and alchemy instruments, determining the gravity, humidity, wind level, temperature, star position and other important parameters here.

Natasha stood out of thin air with a long sword in hand, guarding all around.

Time passed minute by minute, the quiet night only the sound of the undercurrent, Natasha's eyes looked around a few times, and then fell on Lucian's face, because of the position she was standing, she could only see Lucian's side face, that handsome face that was usually familiar to the extreme, at this time there was no accustomed gentle smile, no gaze at herself, only a preoccupied expression and deep eyes.

In this kind of relationship, Natasha not only did not feel bored and lonely, but had a sense of peace and tranquility, and smiled while looking at Lucian's focused side face.

Suddenly, there was a sound of water below, and a huge black shadow appeared on the surface of the sea.

With a bang, a sea monster dozens of meters long emerged, black and pressed like a hill, it looked like a freshwater crocodile, but it was so huge, so weird, the scales all over the body shimmered mottled under the silver moonlight, and the breath was strong and terrifying.

This is a sea monster that rules the nearby seas, and it senses the invasion of threatening creatures!

Natasha turned her head, her eyes narrowed slightly, and there seemed to be a silver-gray sword light shining in her silver-purple clear pupils.

The sea monster suddenly froze in mid-air, and then turned and dived down as if frightened.

Although they are sea monsters, they are more like monsters!

"Its instincts are sharp. Lucian's smiling voice reached Natasha's ears.

Natasha said a little embarrassed, "Disturbing you?"

Although the husband and wife don't need to see each other, as a knight, Natasha still feels that she has been a little negligent and has failed to fulfill her responsibilities.

"No, the data collection is complete. Lucien put away the portable lab.

Natasha smiled and said, "Did you find anything wrong?"

"One set of data doesn't show anything. Lucien's answer seemed to indicate that he had a clear direction.

............

In the depths of the endless ocean, Natasha looked at the small island covered with strange red plants in front of her, and said with a solemn face: "We have returned to the place we just passed." ”

"Yes. "Lucien has collected a lot of data over the past month, but he still hasn't been able to avoid it.

"What did you find?" Natasha didn't notice anything unusual at all, except for the slight changes she felt in her body at times, and could only ask Lucien what she saw in the data.

Lucien replied, "I have seen from the information that there is a mysterious 'Blue Gate' in the depths of the endless ocean. ”

"That's right, the 'Azure Key' is a legendary material bred from the 'Azure Gate', and it has become one of the thirteen legendary fourth-order items today after being refined by generations of the strongest people of the Sea Clan, but the 'Azure Gate' is like the 'Chaotic Starry Sky', only the strongest people of the Sea Clan who have mastered the 'Azure Key' can discover it, or be favored by luck. Natasha recalled the information she had read, "And many legendary powerhouses suspect that the 'Azure Gate' does not exist at all, and belongs to the myth imagined by the Sea Clan based on the legendary item 'Azure Key'. ”

"Anyway, we'll have to find out. Lucien seemed to be sure of something.

Suddenly, an ethereal singing voice came, making Lucien, a legendary third-order powerhouse, couldn't help but get dizzy, as if his soul was attracted by the shock.

"Be careful. Lucien's magic was cast, and Natasha, who was trying her best to fight, quickly got out of the way.

"The song of the merfolk, the merfolk of the legendary rank?" Natasha looked in the direction from which the song came from. (To be continued......)
