Lin Yu'an immediately stood up, intending to fetch the Thunderbird, and walked to the door, listening intently.
Apart from the howling wind, he heard a sound as if something heavy were sliding across the roof.
This sound startled him! He instantly realized the potential danger, fearing that something might be wrong with the chimney.
"No, I have to go out and have a look immediately."
"This snow is wet snow, with a very high density and extremely heavy. If it accumulates on the roof, especially on the windward side of the chimney, it might exert immense pressure on the structure."
"The sliding noise just now was likely a large piece of accumulated snow falling from above and hitting the chimney."
"If the dry stone structure of the chimney becomes loose or collapses due to impact or heavy pressure, not only will there be a big hole in my shelter."
"More importantly, I will lose my only source of warmth, which in this blizzard is equal to a death sentence!"
