"You?"
Anna and the others were stunned.
Lin Wu gave a faint hmm in response.
In Lu Guichi's plan, he did not intend to let her descend into the mine originally, but he had to retrieve something from the Underground Palace tomb. Without her, to open the circular platform and take the item, he would probably have to use his own blood.
Since her blood could open the platform to extract the contents, just like his blood, it should also be special enough to withstand the black fog outside.
Bo Yuting and Gu Shiqing had both come to this realization. After a moment of silence, they turned towards Anna and the others.
"You must not reveal a single word about everything that happens underground, understand?"
The others, not understanding the situation, instinctively sensed something was amiss and nodded in agreement.
