Jing Tian, Legend of the Sword and the Chivalrous Man 3, why do they collect five spirit beads? Isn't it just to send the box to Tianchi?

Dear landlord Jing Tian, they collected five spirit beads to repair the Lock Demon Tower. It was because Lu Ye gently pulled out the magic knife, and then it broke. Then, in order to save trouble (perhaps), the leaders of Shushan sent Jing Tian and others to Zhu Ling to repair the tower. I don't know how to play TV, but this is the game anyway.
