What is the ending of Princess Pearl?

Swallow and others opened a perfect noodle restaurant in Nanyang on the way to escape. Gan Long personally went to Nanyang to welcome them back to the palace, but it was revealed that Gan Long was the enemy who killed Xiaoyan's father. Gan Long sent someone to investigate and clarify the misunderstanding. After Wei Zi and Erkang decided to go back to the palace, Yongqi had to go back to the palace with Gan Long because she found the call of the princess, but the swallow could not bear Yongqi's unfilial duty, fearing that the princess would commit suicide again, saying that there was no Ningxiang Pill to save people, and she returned to Dali with Xiao Jian and Benjamin. Swallow kept the agreement with Yongqi for two years, and Benmingjie also kept Swallow alone! Until Xin Rong gave birth to a son, Yongqi resolutely left and gave up everything! On the day of reunion with swallows, Benjamin left a blessing and quietly left.
