Duncan listened in silence, when suddenly his heart skipped a beat. He noticed the last sentence the other party had said: "...what does this mean?"

The Black Sun was silent for a few seconds, then slowly asked, "Do you remember how many intelligent races there are in the boundless sea?"

Duncan was stunned when he heard this. For some reason, he felt a trance in his mind, but he still subconsciously said, "I remember there are four races..."

He suddenly stopped.

"Which four?" the Black Sun asked in a low, calm voice.

Duncan didn't answer. He already understood what had happened. A huge shock echoed in his heart, and he didn't know how to speak for a moment.

After a brief silence, the Black Sun's voice remained calm: "You still remember that they existed, but you don't know who they are or what they look like. I also remember that they existed, but I can't remember what they look like either...because those who should have remembered them have forgotten them in a slow but irresistible decay, and in the end, the world corrected this result...at the cost of the Sanctuary's operational life."

"Fire-usurpers, this is what has been happening in our world. It has happened before, and it is still happening now. The Black Sun disappearing from the eyes of the world is just an insignificant part of this constantly repeating collapse." "The Black Sun, where exactly is its main body hidden?" Duncan gently reached out and straightened Alice's head, which was tilting. "I'm getting more and more curious about it."

Alice listened as if she understood, "Then...are we going to find its main body?"

"No," Duncan shook his head with a smile, "That's for later. We still have serious business to finish."

"Serious business?"

Duncan's expression was subtle: "...analyzing the route, have you forgotten?"

"Oh, I forgot!"
