"She isn’t here?" Bai Qi was genuinely surprised. The first thing she had done was contact Mu Shang, and then Qiao Er soon after. Bai Qi would have never led Lu Yin to the first array base without the minimum due diligence. She had only gone to look for Lu Yin after learning that Qiao Er had lost the key. The former general had not even known that Qiao Er was not at the array base.

Lu Yin's expression remained as calm as ever.

Bai Qi had called over a Lockbreaker and asked them to inform her of Qiao Er’s whereabouts. The man was one of Qiao Er’s followers, and he was just a Discerning Elementary Lockbreaker. He respectfully answered, "Grandmaster Mu's birthday is fast approaching, so Miss Qiao Er has gone to help prepare the birthday celebration. She is not here right now."

The Lockbreaker did not recognize Lu Yin, and given the man’s cultivation, it was impossible for him to have seen what had just recently happened at the fourth array base. "A month ago."

Lu Yin's eyes grew cold. The woman had left before Lu Yin had even arrived on the rear battlefield, but this matter had never been mentioned to him. He asked in a casual tone, "I heard that the key to the Coiling Knot down below was lost, right?"

The Lockbreaker replied, "That’s right. Miss Qiao Er accidentally lost it."

"Then what’s the plan to open the sourcebox array?" Lu Yin continued.

The Lockbreaker was completely unbothered. "Open it? We can think about that later....
