Not long after the journey to the end of the world began, Duncan had an agreement with the Black Sun - when he arrived at the border of order and confirmed the cornerstone of the new world, he would respond to the other party's request for a place in the new world, and at that time, the Black Sun would show him a "clue" related to the new world.

Now, the Lost Homeland has arrived at the Sea of ​​Ashes, and the time for the appointment has come.

Deep in the captain's room, Alice sat obediently with her back to Duncan. The navigation key slid into the keyhole of the doll with a click and turned on its own with a slight friction sound. After the familiar slight dizziness and reset of perception, the place around Duncan had turned into the spacious, magnificent, yet extremely gloomy hall of Alice's mansion.

The dark-colored door of the mansion covered with intricate patterns stood quietly at the end of the carpet. Sunlight seemed to be floating faintly between the gaps in the door. The projection of the black sun should still be waiting outside the door.

However, Duncan did not go directly outside to keep the appointment, but turned and walked into the depths of the mansion. He found Alice, who was holding the drawing board in a daze, in the navigation cabin, and then he returned to the hall with the puppet and came to the front door.

For some reason, he hoped that this doll would witness everything he experienced in this "end of all things" from now on.

Alice didn't think too much about it. She was just very happy, as happy as she was every day. She seemed to be looking forward to meeting the "big ball of meat on fire". As a "high-level anomaly" who had not lived much in human society, she seemed to be neither afraid of the black sun nor showed any resistance to the dangerous "ancient god".

Duncan arrived at the gate of the mansion, and just like last time, he pushed open the half-closed door effortlessly - accompanied by the creaking sound of the door hinges, the door that seemed heavy but actually seemed weightless opened, and the bright but not scorching false sunlight came in his face, filling his vision with splendor and magnificence.

In a bright shell of flames, the pale, deformed pile of flesh and blood slowly expanded and squirmed, and the huge eye was half open and half closed, as if it was looking at me in a dream: "Ah, Fire Usurper, you appear... Are you here to respond to me?"

Duncan faced the sunlight and said, "I have now reached the end of all things and confirmed the foundation of the new world. Now, as promised, I come to meet you."

The flesh and blood tissue inside the black sun seemed to become more active. The flames on its outer shell slowly rose, and low, overlapping vibrations came from between the countless tentacles and lumps. "Ah, it sounds like you have made great progress... Then about my initial request, the location in the new world..."

"Okay." Duncan responded concisely without waiting for the other party to finish.

Perhaps because the answer came too quickly, Black Sun seemed to be stunned for a moment. The wriggling and trembling of its flesh and blood paused for a few seconds before it hesitated and spoke again: "Are you sure..."

"Yes, the new world is big enough to keep a place for you—and the 'home' in your memory," Duncan said seriously, "but the premise is that the new world can be completed as planned."

"...Aren't you worried that I might become a 'dangerous factor' in the new world?" Black Sun was puzzled at this time. "My tribe and I have been exiled from this shelter for 10,000 years, and you are going to take me and other tribes in the shelter to the new world. Aren't you worried that this might become a hidden danger?"

"I've said it before, the new world is huge," Duncan said calmly, and emphasized it again, "huge - your civilization is not an immortal species, and the 'hidden dangers' you mentioned will be eliminated under the vast spatial scale and the accompanying time scale. Within a sufficiently safe period, your civilization will not have the opportunity to come into contact with others. As for you yourself..."

Duncan paused and a smile appeared in his eyes.

"As one of the 'Ancient Kings' when the Sanctuary was founded, you are familiar with the original blueprint of the Infinite Sea and all the system loopholes. Based on your current understanding of the 'Sanctuary', I guess... this world actually has no ability to 'exile' you. In other words - if you want to return to the Infinite Sea, then you would have returned as early as the day when the Ancient Kingdom of Crete raised Vision 001 into the sky."

He raised his head and stared quietly at the huge eye in the center of the creeping sun disk.

"During the construction of this shelter, there was no record of war between the ancient kings. Everything was the result of negotiation. You were exiled voluntarily, but the offspring and residue that grew from you... caused things to get out of control."

Black Sun was silent for a moment, and finally spoke slowly: "The establishment of the shelter was very 'extreme'. At that time, there was not even a trace of extra resources and time to waste. Long Night failed twice, and we must succeed the third time... No one had a choice."

"Thank you for your rationality. Let's stop making meaningless attempts and assumptions. I have my own plans for the new world. Now it's time for you to fulfill your promise," Duncan said with a serious expression. "You said you have 'evidence' about the new world. What is that?"

The black sun did not speak, but slowly stretched out the tiny tentacles on the edge of its sun disk. At the edge of the burning false corona, a limb suddenly extended out - there seemed to be something rolled up at the end of the limb, which crossed the long distance in space and was accurately delivered to Duncan.

Alice, who had been daydreaming for a while, was startled and immediately came over curiously: "What is this?"

"A letter." The black sun's trembling voice echoed in this empty space, and then the "tiny" tentacle slowly stretched out, and an object appeared in Duncan's eyes.

It was just a silver-grey cube, like a metal ingot, with a side length of only about ten centimeters. There seemed to be some patterns engraved on the surface. Although the shape was somewhat curious, it was not as "remarkable a thing" as Duncan had initially thought.

He looked at the small metal cube in confusion, and noticed that the surface of the cube had a faint translucent and fuzzy texture - considering that it was only the projection of the black sun that came here, it was obvious that the cube it showed was also just a projection.

The main body of this cube should be with the Black Sun, somewhere outside the real dimension.

Duncan frowned suddenly as he noticed some patterns on the surface of the cube.

The Black Sun seemed to have expected this, and when Duncan's sight changed, it considerately brought the projection of the cube in front of Duncan and slowly rotated it, showing its every surface.

Duncan saw the outline of a human figure, standing on a coordinate map with many markings and reference points.

On the second surface, he saw a series of circles, arranged from smallest to largest.

On the third surface, he saw intersecting lines, and the intersections of the lines seemed to show some kind of mathematical pattern.

On the fourth surface, there is a crooked picture that looks like a child's doodle. The childish brushstrokes are out of place with the precise and seemingly meaningful patterns on the previous surfaces.

On the fifth surface, there are countless concave dots that seem to be randomly distributed. It seems to be... a "star map" representing constellations or similar celestial systems?

Duncan's eyes fell on the sixth surface.

It's covered with distorted symbols!

They originally seemed to be many different kinds of text, but under the influence of some force, all the text, or the information represented by the text, was distorted into an unrecognizable appearance. Duncan even felt that the distorted symbols were alive. When he stared at them, each of their lines was shaking and reorganizing on its own, making it impossible for him to distinguish their true outlines.

Duncan subconsciously reached out to the cube, but his fingers went straight through the phantom.

The voice of the Black Sun reached his ears: "Its 'entity' is not here, but I can describe its state to you -

"This is a metal ingot with the hardness of steel, but surprisingly light; it is hollow inside, hiding a powerful energy source, and I cannot peek into its specific structure without damaging its integrity; it seems to have some kind of powerful 'mechanism' that releases information outward, but this mechanism is also hidden inside it.

"And one last thing: it seems to have originally carried more intelligence, including the 'text' you noticed that is no longer readable, but this 'intelligence' cannot be read.

"It even made sounds at the beginning, but they were just chaotic noises. It kept releasing some kind of 'signal', but even I couldn't understand what it was. And now, its release process has basically stopped. I can't tell if it's because of a malfunction or because of energy depletion... But it shouldn't have anything to do with energy, because until now, the energy reaction inside it is still very strong."

Duncan did not speak for a long time while listening to Black Sun's story. He just stared at the rotating cube quietly. After a long time, he finally broke the silence: "So, this is a letter, a letter sent from the 'New World' to the 'Old World' - is that what you mean?"

"Yes."

"But how can we be sure of that?" Duncan couldn't help asking, "How can you be sure that it's not another 'relic' from the Great Oblivion? Just like those other twisted fragments."

"Because it comes from a place where theoretically it is impossible for any 'fragments' to exist." Black Sun said calmly.

Duncan frowned immediately: "Where there can't be any debris?"

“…The creation of the world.”

The scene was instantly silent.

Duncan opened his eyes slightly and looked at the projection of the cube in astonishment, looking at every surface that tried to convey various information, as well as the erased words.

This is a letter.

But who sent this letter?
