Can you summarize the story about the serpent in the barn from Chapter 35?

Chapter 35 recounts an incident where a fearsome serpent entered a barn, causing panic among everyone present. They were afraid to even go outside, fearing the serpent might move further into the house. Amidst the fear, one person fearlessly brought a vessel full of milk and placed it before the serpent. After satisfying itself with the milk, the serpent disappeared, eluding everyone's eyes. The entire barn was searched, but no trace of it was found. While most people were relieved, a person named Nevasakar felt disappointed because he had hoped to see the serpent as it was leaving, just as he had seen it when it entered.
