Third Aunt Du blew the whistle three times. Everyone waited for two minutes, but nothing happened.
"Master, does the whistle do anything?" Little Wu asked.
"It should." Third Aunty Du said tentatively, "At that time, I already made arrangements with them. If something happened, this would be our signal. I tried it twice after that, and it worked both times."
"But you've already been blowing it for such a long time, but nothing's happened. Could it be that it's no longer here?" Bei Gong Tang said.
"I can't say for sure. I've been on good terms with them for over tens of years. I hope that nothing has happened to them. Let me try again." Third Aunt Du said worriedly.
After speaking, she blew it again.
"Something's happening." Sima You Yue looked towards the peaceful lake as she spoke.
Just as she spoke, a little head peaked out from the lake, looking at them warily before noticing Third Aunty Du and dashing out of the water.
