Huo Yao simply smiled. She turned to place the untouched cup back onto the coffee table.
What she didn't say was that she simply had very sharp ears.
Wu Yue touched his nose. Just as he was about to speak, he saw Qiao En's assistant hurriedly coming back after leaving earlier.
"My apologies. Prof Qiao has something urgent to attend to. Let me see you off," said the assistant quickly.
Wu Yue could tell it was very urgent, so he did not want to stay and disturb them. He got up and said, "Since Prof Qiao is busy, allow us to take our leave. You don't have to show us out. I'm sure we can find the way on our own."
The incident was very serious, so Qiao En's assistant did not even bother to smile politely. Instead, he heaved a sigh of relief and said to Wu Yue, "Ok, thanks."
After the assistant walked them downstairs, he went back to the laboratory.
