If it hadn't been for Cao Zhen, she wouldn't have chosen this entrance.
She saw Cao Zhen inspecting the broken drum in front of him, but this was not the only drum here. Soon, four people, one who seemed the most inconspicuous, flew down to one of the drums, touched it with his hand, glanced at the drumstick, and finally looked at the door behind the drum, thoughtfully listening to the sound of drumbeats coming from the tower.
Situ Di lagged slightly and flew down behind them, bowing to Immortal Bi Yue beside him, "I have seen Immortal Bi Yue. In some time, our Five Sounds Sect will face a Sect Tribulation, and we will rely greatly on Immortal Bi Yue."
Earlier, when they were outside, there were too many people, and he did not want to draw attention, so he didn't greet Immortal Bi Yue. Now that they were inside the relic, where everyone was from the Great Teaching, especially Immortal Bi Yue who would help them with their Sect Tribulation, naturally, he had to greet her.
