Ye Jiuge could not wait until the next day, so she used the Ye Clan's distinctive secret signal to call for Ye Yu.
After approximately the time it takes to drink a cup of tea, a soft knock came from outside Ye Jiuge's window. When she opened the window, nobody was outside. Anyone else would have been scared to death. However, Ye Jiuge merely said, "Come in."
Something flitted past the window. Then, Ye Yu became visible in Ye Jiuge's house, revealing his beautiful face.
"Eldest Miss, why did you call for me?" Ye Yu had recently been cultivating, and Ye Jiuge had not summoned him for some time.
"Go and keep a close watch on the Su Clan. If anything happens, inform me immediately!" Then, Ye Jiuge added solemnly, "Keep an eye on the Su Clan's Old Master in particular."
