"There's one more thing," Fang Xingjian said. His gaze flashed slightly as he recalled the wordless monument on the Moon's relics. "Has Earth found out about the origins of the wordless monument?"
"No," Fang Yuehe replied, "The Moon's relics are too strange. The wordless monument has knowledge that far surpasses the level of our civilization. Yet, the word, 'left', is a character from our Xin Country's language."
Fang Xingjian said, "It could have been left by someone from a parallel world. However, I feel that it's also very likely that it was left behind by some civilization on Earth from way back."
"A civilization from way back?"
"Get people to investigate this thoroughly and search through all the extents of the planet. Let them see if they can find similar relics. Then have them sort out the findings into a document and give it to me."
