This Doctor Is Too Wealthy-Chapter 704 - 564 Someone has taken a step ahead.

"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."

Du Heng was too excited; he had drawn the crucial insight about Cao Binghe from the medical texts.

Still overjoyed, Du Heng turned and headed out the door again.

Seeing this, Wu Shengnan was dumbfounded and quickly grabbed Du Heng. "Why do you always leave conversations half-finished? And where are you planning on going now?"

"To the hospital. I need to confirm my findings and deliver the good news to Cao Binghe."

"Are you crazy? We promised Tingting we would go to lunch." Wu Shengnan wouldn't let go of Du Heng. "Tingting is waiting for us at school right now. What do you mean you're not going?"

Du Heng tried to pull his hand away, but Wu Shengnan held on too tightly; he couldn't break free at all, so he patiently said, "That Dr. Cao I told you about, his eyes... he can't see.

Many experts in the Capital have seen him, but none could find a solution. It's as if he's been sentenced to death.

I took a look this morning too, and I couldn't find the cause either.

But now, I've figured it out. He can regain his sight!"

Du Heng spoke with great excitement, but Wu Shengnan remained unmoved. She seemed to understand, though. "So you've figured it out. You're brilliant, more brilliant than all the experts in the Capital.

But can't you wait until after lunch to go?"

Du Heng started to grow impatient. Just as he was about to speak, Wu Shengnan continued, "What's the use of being so anxious right now? If you go, can you treat him immediately? If he's treated, will he get better right away?

He hasn't been ill for just a day or two; what difference will these few minutes make?

But your niece is different. That girl has classes this afternoon and evening. If you miss lunch with her today, do you think she'll be able to concentrate on her studies this afternoon and evening?"

Du Heng was stunned silent by Wu Shengnan's barrage of words.

She's right. Cao Binghe has been blind for more than a day or two; rushing over a few minutes earlier doesn't seem to make much difference.

The main thing is, even if I went now, I couldn't treat Cao Binghe on the spot. And to treat Cao Binghe, I absolutely need Lan Changhua by my side.

But if I stood Du Xuejing up, that girl would probably be genuinely furious.

"I was too excited. My mistake." Having thought it through, Du Heng apologized on the spot. "Hurry and get dressed. Let's go have lunch with Tingting now."

"That's more like it."

Wu Shengnan rolled her eyes at Du Heng, quickly changed her clothes, then walked out arm in arm with him.

The place for lunch was the same one where they had previously invited Du Xuejing and her classmates; they were quite familiar with it.

When they arrived, Du Heng saw the same familiar faces.

The moment these young women saw Du Heng, they all called out in bright, clear voices, "Little Uncle!"

And this "Little Uncle" filled Du Heng with joy; even seeing Du Xuejing still giving him the cold shoulder didn't affect his good mood.

But when Wu Shengnan appeared behind him, and the girls chimed in with another cheerful "Hello, Sister!" Du Heng's mood instantly soured.

"You're messing up the seniority by calling her that!"

Du Xuejing, who had been pretending to be angry, dropped the act and jumped up. "What's wrong with all of you? Call her 'Little Aunt'! Are you all trying to take advantage of me?"

"No, we'll just call her Sister!"

"Sister, you're so beautiful!"

"Sister, are you really a police officer?"

The young girls paid no mind to Du Xuejing or Du Heng. Calling out "Sister," they immediately surrounded Wu Shengnan.

And Wu Shengnan, amidst the chorus of "Sister," gradually lost herself, her delighted laughter piercing through the private room.

The playful banter was brief, but it effectively bridged the gap between them.

During the meal, Du Xuejing suddenly asked Du Heng, "Little Uncle, can you stay a few more days this time?"

Du Heng raised an eyebrow. "Why?"

"I have classes today and tomorrow, but this Saturday, I don't have any." Du Xuejing started to act pitiful again. "Aren't you and Little Aunt going to take wedding photos? I want to go too."

Du Heng completely ignored Du Xuejing. "What's wrong with you? We're going to take wedding photos. Why would you tag along? You're not coming. Go find something else to do."

Du Xuejing was unhappy. She tried acting cute, making threats, and pulled out every trick in the book, but she couldn't make Du Heng yield.

Seeing that this approach wasn't working, she switched targets and focused her firepower on Wu Shengnan.

How could Wu Shengnan withstand Du Xuejing's barrage? Besides, as the newly-minted 'little aunt,' she also wanted to make a good impression, so she smiled and promised.
