What is 'police'?

Yun Jifeng and his evil father almost died or rage when they heard Lu Aotian's arrangement.

"Who does he think he is to boss people around?" General Yun fumed.

"He does have the power..." shrugged Yun Jifeng.

"Well, he won't be holding onto it much longer." General Yun scoffed and took out his phone.

"Xuanxuan, are you free right now?....Yes, come home okay?"

"Father, why are you calling that girl over?" They were doing something ilegal. Why would his father call Yun Xuan?

"I need her help." he said.

"Father, are you crazy? She's your daughter and my sister."

"All those girls I've used before are my daughters too, and aren't you my son?" he was indifferent.

"That's different. Yun Xuan is the only daughter you love. You said you would never expose her to wickedness."

"And I also promised to pamper her all her life. Haven't I always loved her and given in to most of her demands? She should be glad that I kept one promise.
