Pawns.

Shi Lang pacified Zhu Lingxue and Yun Tian. After giving them careful instructions, he left the Zhu Family mansion. Outside the mansion, Yao Jiming asked him, "Young Master, why did you show favor to Lady Zhu?" 

While gazing at the bustling marketplace, Shi Lang smiled and said, "The Zhu Family wanted to change city governance. This incident may have set them back for a few days, but they will not stop. So, to ease my troubles, I thought, why not instill a pawn of my own in this game of chess." 

Yao Jiming was smart enough to understand what Shi Lang meant and confusedly asked, "Young Master, how will this pawn help us? Do you think that Lady Zhu will go against her father and family?" 

Shi Lang smiled and nodded as he said, "What happens when you set a caged bird free to explore the limits of the sky, Brother Yao?" 

Yao Jiming took a deep breath and said, "Young Master, you are indeed unfathomable for a dimwit like me."
