Chapter 28 mentions a correction regarding a previously told story. What is this correction and what new narrative does the chapter begin to introduce?

Chapter 28 makes an important clarification regarding a story referenced earlier in the Satcharitra. The text notes that a story about a back being beaten and chest being pressed due to a scorpion sting was previously attributed to Chapter 10. However, a devoted follower pointed out that this story about Bhimaji Patil of Narayangaon is actually found in Chapter 13. After making this correction, Chapter 28 begins a new narrative that promises to reveal Sai's compassionate nature. It introduces a trustworthy and obedient clerk, or munshi, named Laxmichand, who worked in Mumbai for the Ralli Brothers, a firm of Greek merchants.
