"Hahaha, I understand now." Du Heng suddenly burst into laughter. "I figured it out."
But this sudden laughter startled Wu Shengnan, who was about to change clothes, causing her to shiver and reflexively swat Du Heng. "You went out early this morning, and now you're acting strange?"
Du Heng was too excited. "You don't understand. I have found the root cause of Cao Binghe's illness."
As soon as he finished speaking, Du Heng laughed aloud once again.
There's no such thing as incurable diseases in this world; it's just that those who study medicine sometimes lack in-depth knowledge or haven't fully grasped what our ancestors left us.
The confused look on Wu Shengnan's face deepened. "Who is Cao Binghe? What happened to him?"
"Cao Binghe, a doctor at Good Friend Hospital and also my friend, his eye..." Du Heng excitedly began his explanation but abruptly cut it off. "Forget it, there's no use telling you. You wouldn't understand."
