Old Master Qiu's status was unique. He was the leader of the Peach Blossom Cove. Strictly speaking, he was Xiao Zeyu and Xiaoying's benefactor. If he hadn't said that he would take them in, Bai Jiuxiang would have had to continue fleeing with the siblings and wouldn't have been able to settle down.
Because of this small amount of kindness, Xiao Zeyu had to catch them red-handed. He had to seize the opportunity to deal with Big Father Qiu and Big Aunt Qiu, leaving Old Master Qiu blameless.
Everything had been planned. He had deliberately leaked Su Qing's whereabouts and created a tense atmosphere. He had said that no one would leave. He had wanted Auntie Qiu to believe that Su Qing was seriously injured and even allowed her to go home and report.
Xiao Zeyu had already sent a good individual, so he waited for Aunt Qiu and Father Qiu to enter the trap.
However, he didn't expect Xiaoying to suddenly go to the Qiu family and disrupt Xiao Zeyu's plans.
