When did the new glory of returning to pearls appear? Why did Swallow and Mei have to be separated for two years?

Xinrong should appear in the second film. I think it should be after ChristianRandPhillips came, before the mass exodus. As for being separated for two years, they helped ChristianRandPhillips escape, and the emperor imprisoned Wei Ziyan. Maybe they robbed the prison again, and all the people, including Benjamin, escaped together. When the queen went after Wei Zi, she was blind and Erkang was injured. The emperor knew about it. The emperor himself went to take them back to the palace. At this time, the swallow knew that the emperor was her father's enemy, and Yongqi, the son of the enemy, was entangled in her heart and didn't want to go back, but Yongqi had to go back because of her mother's call. So he made a two-year agreement with Swallow to wait for him. Two years later, they finally met under the sea of flowers.
