Which episode is Zhu Yuanzhang's dream of killing Judy?

Episode 4: Late at night, Judy dreamed that she was holding a sword and sneaked into the hall. He found that his father Zhu Yuanzhang was not dead and glared at himself. Zhu Yuanzhang ordered someone to send Judy's biological mother, who died on the spot by Zhu Yuanzhang's sword. Zhu Yuanzhang came to Judy. Although Judy knelt down and begged for mercy, Zhu Yuanzhang slashed at Judy with a knife. When I woke up from my sleep, I found Yao sitting beside him, so I talked to him about the dream.
