There is a strange smell of rust and dust in the air, which is the eternal smell of the "Steel Teeth" shelter. Gu Yuan wrung out the last clean rag in his hand and carefully wiped his sister Gu Xiaoxiao's forehead.
The girl was lying on a simple wooden bed, breathing weakly. Her once-nimous eyes were now tightly closed, and her long eyelashes seemed to be condensed with gray dust. On all the exposed skin on her face and arms, there were several gray spots the size of fingernails, like peeling mold spots on old walls, with an ominous air of death.
"Brother..." Gu Xiaoxiao's lips moved and her voice was as thin as a gnat.
"Xiaoxiao, I'm here." Gu Yuan immediately came over and held her cold hand, "How do you feel?"
"Cold..."
One word pierced Gu Yuan's heart like an ice pick. He grabbed the only thick coat around him and covered his sister, but he knew that it was useless. This kind of coldness comes from inside the body, from the bone marrow.
