Taran El, an outstanding elven scholar, an expert in mathematics, mechanics, and natural history, is the recipient of four lifetime honors awarded by the Academy of Truth.

A person who studies hard, a person who works diligently, a person who can stay in the laboratory without sleep, a person who makes Lucrecia worry at any time whether he will die suddenly at the research site.

Now, this learned scholar announced in front of everyone that he was helpless against the geometric light body that fell from the sky.

Lucrecia raised her head, her gaze passed over the crystal ball in front of her and fell on the opposite window. A magnificent light was spreading from that direction. Even though it was midnight, the entire sea area still seemed to be bathed in "sunshine", and among the light, the luminous geometric body like a hill was still floating quietly above the sea, and its flat wall of light was like a steep cliff, stretching between the sky and the sea.

Another small boat crossed the sea filled with light and headed towards the interior of the glowing geometric body, ready to pick up the research team that had completed their rotation mission near the "stone ball".

Lucrecia sighed, withdrew her gaze from the window, and looked at the table next to her - a strange-looking, gray sphere was placed on the shelf on the table.

The surface of the sphere is rough and has a rock-like texture. There are strange, undulating and irregular patterns all over the surface. It is not good-looking, but is filled with an indescribable sense of mystery.

In the center of the huge geometric light body floating on the sea, there is a strange "stone ball" with a diameter of ten meters, and the one in front of Lucrecia... is a smaller and exact replica of the stone ball.

It is almost the only "result" after such a long period of research by a large group of experts and scholars.

"Master Taran El has returned to Breeze Harbor to rest. Strictly speaking, he was 'kidnapped' back to Breeze Harbor by his students," Lucrecia shook her head and said to her brother on the other side of the crystal ball, "If he doesn't rest, he might die suddenly outside - for an elf, dying suddenly at the age of 500 is really too young.

"When he left, he seemed very depressed because this 'fallen object' was beyond our understanding. Whether it was the glowing area around it or the nature of the sphere in the center, it was a mystery to us.

"The researchers scraped some samples from the 'stone ball', but the analysis results showed that they seemed to be fine stone powder. There was no progress in the exploration of the interior of the stone ball - all methods were ineffective, including supernatural powers. It seemed that the thing was wrapped in a dense 'shell', hiding all its secrets. At least until now, we have not made up our minds to conduct destructive... 'tests' on it.

"After all this time, we have only reached one consensus, which is... this huge geometric light body is definitely something that fell off the rune ring around Vision 001. This is the conclusion given by the 'High Tower' in Breeze Harbor. They carefully observed the gap on the edge of Vision 001 and found that the missing part is consistent with the 'geometric light body'."

Lucrecia said a lot in one breath. It was obvious that she had accumulated a lot of annoyance during this period. Tirian was a good listener. He did not interrupt his sister's story. He spoke slowly until Lucrecia finished speaking: "Has it been confirmed that it was a part that fell off from Anomaly 001? Lucy, father had warned the Church of the Four Gods about this before. He said that the 'Sun' might be declining."

"I heard about this incident," Lucrecia nodded slightly. "No one dared to ignore the warning from Captain Duncan, although most people's first reaction after hearing this warning was to feel nervous and fearful about the Lost Homeland..."

Tirian curled his lips. As someone who had met with Duncan Abnomer frequently recently and had witnessed his father's new methods with his own eyes, he could not comment on anything at this time and could only change the subject: "What follow-up plans do you have? Regarding the issue of 'the sun'..."

"What's the plan? Throw this big stone ball back into the sky? Re-embed it in the rune ring of the sun?" Lucrecia shrugged. "I'm afraid only the ancient Kingdom of Crete knows how to repair the sun in the sky."

Tirian was silent.

Lucrecia was silent for a moment and then suddenly asked, "Does father know about my 'research' here?"

"I haven't told him," Tirian shook his head. "I won't say anything without asking for your opinion. What? You want to ask him for help?"

Lucrecia obviously hesitated for a moment, and seemed to be somewhat tempted, but she soon shook her head: "I'll think about it again. My father may not be able to help with this matter, and... well, I'm just a little afraid of him."

"He's actually quite easy to talk to now," Tirian laughed. "But since you don't want to, I won't interfere. But let me tell you in advance, even if I don't tell him, he might get the news someday. After all, he already has connections with the church and the city-state. If he's really interested, I won't dare to stop him."

Lucrecia waved her hands in annoyance. This "sea witch" who was shrouded in mystery in the eyes of outsiders never hid her emotions in front of her family: "I know, I know - let's not talk about this. When can I get the spirit world lens you mentioned before?"

Tirian: "..."

Two seconds later, Lucrecia's dissatisfied voice rang out sharply from the crystal ball: "You forgot again??!!"

※※※

"You don't look well, Tirian."

Duncan arrived at Southport early in the morning, and after seeing some fatigue in Tirian's expression, he couldn't help but say something.

Tirian rubbed his forehead and sighed helplessly: "There are too many things to worry about recently."

This was not an excuse. He had indeed had a lot of things to worry about recently. Managing a city-state obviously required much more effort than managing a fleet. But then again... the impact of his sister's intensive nagging for two hours on his complexion was obviously a factor that could not be ignored.

But soon Tirian avoided this slightly awkward topic. He did not mention Lucrecia, but straightened his expression and said, "I called you here so early today to tell you that the submersible is ready."

Duncan raised his eyebrows when he heard this: "So fast?"

"After considering that the passengers don't need to breathe, many preparations can be accelerated," Tirian nodded. "And the submersible secretly built by the previous Frost Government was built based on the blueprint of the Queen's era. Although there are many improvements, the basic principles have not changed much. If you just want to figure out how to operate it, it is actually a very simple matter."

Duncan looked at Tirian for a while, then looked away and nodded with satisfaction: "Very good, take me there."

"You want to start right away?" Tirian was a little surprised. "We can do some more tests. I asked you to come here today just to let you see it with your own eyes..."

Duncan interrupted: "You should have done some tests, right?"

"... a little bit," Tirian hesitated, "after completing the system verification, I arranged for two undead sailors to conduct a short dive of several dozen meters last night, mainly to confirm the operating procedures and working status of the submersible. There were no problems..."

"That's enough," Duncan nodded, turned around and walked towards the warehouse leading to the underground facility. "Just think of it as me personally completing the subsequent testing process. Anyway, the official deep diving operation still needs to be carried out by me."

Tirian was stunned for a moment, and could only quickly catch up with Duncan's steps. On the way to the facility in a hurry, he couldn't help but feel some doubts in his heart.

He didn't know if it was an illusion... He always felt that his father looked a little worried today, and this urgency was different from before.

It was as if he had suddenly discovered some clue or touched upon some huge secret, and he was driven by an eagerness to solve the mystery and explore the truth.

And this hurried look... gave Tirian a vague sense of familiarity.

The burly figure in a black coat was walking quickly in front, and Tirian was also walking quickly, trying hard to keep up with him.

The latter looked at the former's back, and as they followed closely, he suddenly realized the source of this familiar feeling -

This feeling seems like it happened many years ago.

This is what my father would do when some clues to ancient relics were found, when a new route appeared on the nautical chart, when news about border areas and mysterious visions suddenly reached the civilized world.

This is what he looked like when he was preparing to embark on a long voyage.

The long-lost yellowed memories emerged uncontrollably from the depths of his mind. The scene of following his father to set sail in the past appeared before his eyes. In the overlapping images, Tirian subconsciously slowed down his pace.

Duncan stopped and turned to look over here in confusion.

"Tirian, what are you daydreaming about? Come on."

Tirian was startled, and hurriedly agreed while taking a step forward: "Ah...Oh, yes father!"

Duncan turned around and continued walking forward, not paying too much attention to Tirian's reaction.

Because a sense of urgency to explore this world surged up again, constantly urging him.

This sense of urgency stems from the harvest from his exploration of the brass key yesterday, and from the sudden unveiling of a corner of the mysterious veil of this world—

A huge spaceship that crashed into this world in a lost era, a creation of an ancient civilization from a hidden history called the "Profane Prototype", and a deep mystery that even great scholars like Morris have never touched.

There are too many unknowns, and the clues that appear by chance make people more aware that the secrets of this world are complicated and entangled, like layers of curtains.

Therefore, any opportunity to explore the truth of the world is invaluable.

Explorers should be like this.
