No one interrupted the old lady's narration, and after saying all that, she seemed tired and closed her eyes again. It wasn't long before she continued to speak.
"The nomadic lands of the Boyegu were actually what is now the eastern side of the Qilian Mountains in Ganzhou City, of course, they would never draw near the oasis of Guyuan Town. Guyuan Town was what is now Ganzhou. It is said that after a fierce battle, Guyuan Town took advantage of the situation to dispatch troops and intervene, which led to the extermination of the Boyegu Tribe.
As for the cave you mentioned, I roughly know where it is. Even though the Boyegu Tribe was annihilated, I think this was merely the consequences for those who participated in the war at the time—the children, women, and slaves of the four great Boyegu families, as well as their cattle and sheep, were all plundered by the Eight Great Families.
