Jin Tiao was not home at that time. They only found out he went to the casino when they asked his family.
Yin Feng and the others found Jin Tiao at the casino where he was gambling. When they entered, the gamblers thought they were there to arrest people and all fled.
Yin Feng caught Jin Tiao and showed him the picture of the ring. He asked, "Do you know where this ring came from?"
"Don't arrest me! I will talk… I'll talk! The ring is my sister's! I stole and sold it!"
Jin Tiao spoke honestly. Yin Feng finally had a target now. They then went back to the Jin family again to find Jin Tiao's sister.
After that, it turned out the person who came out was Jin Hua.
As Jin Hua had gotten plastic surgery, her silhouette was somewhat similar to Jing Xi's. That's why Yin Feng thought she was the king's first wife when he saw her.
