How to find the whereabouts of Tuoba Yuer with Xuanyuanjian?

Looking for Lujiadu in the geodetic map, I found that I couldn't go to the dragon boat. You need to prepare a round to trigger the plot again. A Qiu will get props in houses and shops, and then pretend to be a woman to go boating with Zhang Lie. Tuoba is on the dragon boat. Note: There are officers and men patrolling the dragon boat. You should find the right time to avoid them, or you will be kicked off the dragon boat after being discovered and have to start all over again! )
