In the play, Bai Fengxi returned to Tianshuangmen with Hanpu and put on the clothes of Tianshuangmen disciples, so it was probably because it was too dangerous to destroy the Broken Soul Gate, so he didn't take Hanpu out and left Hanpu to study at Tianshuangmen.
In the original book, Bai Fengxi didn't let Jiuluo people loyal to her escort Han Pu to learn from her teacher until she returned to Qingzhou, and promised to pick up Han Pu five years later. Although she didn't pick up Han Pu on time because of her children, she still picked up Han Pu, and finally Han Pu became a hero.
Han pu's ending
Five years later, Han Pu is a handsome man with unparalleled martial arts, but he didn't wait for Bai Fengxi to meet him. He searched for her in heaven and earth. When he finally met her, he cried like a child. He thought Bai Fengxi didn't want him. It turned out that Bai Fengxi happened to be pregnant that year, and her physical reaction was very serious, so she could not move forward. Now the child will come to pick him up for life. Knowing that Bai Fengxi had married and had children with Black Fox, Han Pu burst into tears again and asked Bai Fengxi to divorce Black Fox, which was naturally comforting.
The carriage drove away slowly, with tears, howls, curses, noises and happy laughter. On the way home, it was so lively. Time is not old, no regrets, everything is so beautiful.
Han Pu grew into a new warrior who unified the Wulin.
