Dumb's family was rather well-off. Did they really have no money to hire a doctor for Dumb? It was only because Dumb's father was unwilling to spend so much money on him.
"How many days have you been left here?" asked Shen Lang.
Dumb tried to count using his fingers, but he could barely lift his hand up.
How strong was he in the past?
"One hand is not enough to count," said Dumb.
That meant that he had been left in the mountains for more than six days. He had no food or drinks for the entire six days and only survived on rainwater.
Without food or drinks, they left him there with broken bones, so he would bleed to death.
Shen Lang had already diagnosed Dumb. He broke five of his ribs; his liver, stomach, and lungs were already suffering from internal injuries.
