Fang Ka glanced at the still unconscious Sonam and then raised an eyebrow: "You mean after the construction of the Underground City?"
Xia Lin immediately realized that she had expressed herself unclearly, and quickly added: "The completion of the Underground City and the concealment of the island took roughly nearly two years. I mean after the completion of the Underground City."
Fang Ka gently nodded: "The Underground City within that island must be vast, right? Even with the goblins' specialized alchemy excavation tools to assist, it still took so long."
Xia Lin promptly nodded: "Yes, it's extremely vast."
"By the way, Master Fang Ka, I think I should first read the memory of that Goblin Knight before continuing to speak with you."
"Because Sonam usually stays in his exclusive Royal Palace conducting research, and only goes out for a round every six months, the routine management and planning of the Underground City are all left to those managers."
