In which episode of Wei Zifu was Rebecca abandoned?

Emperor Wu called the Wangs to the temple, but when they arrived, the Wangs were told that Emperor Wu had something important to deal with and told them to wait for two hours. They said they would wait for Emperor Wu of the Han Dynasty and ask their people to tell him not to worry about them. During the absence of Emperor Wu, the Wangs and sisters wandered around the temple. Wang Sang thought that since Emperor Wu of the Han Dynasty called them to the temple, he paid attention to them, which further proved that Wei Zifu had fallen out of favor.

Rebecca looked at the back seat, very tempted. She sat in the back seat, pretending to be the queen, so that Wang Sang could visit herself, and then she let Wang Sang sit on it. At this time, Emperor Wu of the Han Dynasty appeared. Immediately on the grounds of coveting the back seat, he beheaded Wang Sang and sent He Honger to see Qi.
