"Do you think the three tribes coalition forces will only loot the first floor, but don't know if there are the second and third floors?" Xiao Han joked.

Serena was stunned: "I don't know that after that battle, the entire imperial city and the queen were killed in battle. No one knew what happened after the three tribes entered the underground of the imperial city, but this floor must have been emptied by the coalition forces of the three tribes. As for the two floors below, I only saw it in a fragment."

"Does Faya know?" Xiao Han asked.

"She should know, I don't know. She only told me about the first floor and did not mention the two floors below," Serena recalled and said.

"Then how did you know there is an entrance to the second floor here?" Xiao Han asked strangely.

"It was also seen from the fragments. There are three entrances to the second floor on the fragments, and here is one of them."

"Where did the fragments come from?"

"Only one-third of the snatched out of the library of the Elf Imperial City Academy after the war, and two-thirds were burned."

"How many people have the opportunity to get into this fragment?"

"Successive queens and several elders in the Elders' Council should be qualified."

"So, what's on this fragment is not a big secret?"

"I don't know, but since I saw this fragment, I have put it away and no one can see it again." Serena said.

"You are right, the fewer people know about such a secret, the better." Xiao Han nodded and praised.

"Since Queen Faya has been here, has she told you something special?" Xiao Han continued to ask.

"No, in fact, if she hadn't told me the topographic map here, I might not have been able to find the entrance to this second floor," Serena recalled carefully and said.

"Okay, that's all by luck." Xiao Han smiled helplessly. There was no information, it was really only by luck. If they couldn't find the entrance to the second floor, they had to return the same way.

Xiao Han lay on the ground, tapping the bricks and stones on the ground one by one with his hands, and listening carefully to the sounds coming from the ground. This may be the most primitive method. To determine whether there is an entrance underground, if all of them are real ground, or if the bricks and stones are too thick, you can't hear them, then it will be troublesome.
