Since she found them, there was no reason for Gu Ning to let them go. She should catch them and force them to tell her where He Siyang was.
"I think they must have noticed us when our yacht came close and hid themselves somewhere around here. This is an ancient house, so there could be underground rooms or passages. We can search around to see whether they are hiding here," Gu Ning said. Although she clearly knew where those people were hiding, she had to search for them in order to keep her Jade Eyes a secret.
She wasn't fully prepared yet to tell Leng Shaoting everything about her. If it was possible, she hoped that no one else would know about her rebirth and Jade Eyes.
"No problem." Leng Shaoting had the same idea, then started searching.
There weren't many rooms in the house, so it didn't take them a long time.
Within 10 minutes, Leng Shaoting and Gu Ning found the room above the underground room.
