At this time, Zhang Yu had already reached out to clasp Old Madam Yuan's pulse, gently pinched his fingers, and probed the other party's internal organs with his pulse.

"Huh?" After probing, Zhang Yu suddenly frowned.

"What are you doing, do you want to say that this illness is a bit troublesome?" At this time, Yuan Fei on the side suddenly said with a hint of mockery.

"Xiaofei, don't ...... "Old Madam Yuan wanted to stop her grandson, but before she could say a few words, she was choked back by a violent cough!

"Mom, you're just too kind!" Yuan Fei said indignantly, "We don't see many liars like this? It's just that you just want to take the opportunity to make more money!"

"Ah Fei!" At this time, Chen Tianming on the side finally changed his face, and shouted to Yuan Fei with a gloomy face, "Brother Zhang, he is not a liar! He saved my life! Just a few days ago!"

"What?" Hearing Chen Tianming's words, Yuan Fei's face finally changed!

He doesn't believe Zhang Yu, but he definitely won't distrust Chen Tianming!

Now, Chen Tianming actually said that this Zhang Yu saved his life, combined with what Chen Tianming just said, could it be that the kid in front of him who doesn't seem to have any hair is really a miracle doctor? !

"Brother Chen, don't care, it's okay," Zhang Yu smiled, then looked at Yuan Fei and said, "It's true that you said it, this disease is really a bit troublesome!"

"Grandma Yuan, I just took your pulse and found that except for your lungs, all your internal organs are very healthy, presumably your body must have been great when you were young!"

"Ahem, ahem!" Old Madam Yuan coughed heavily and nodded.

Chen Tianming on the side immediately said: "Grandma Yuan's family is a local martial arts family, and she has practiced martial arts since she was a child. ”

"Then it's no wonder!" Zhang Yu nodded with a smile, then lowered his head and said to Old Madam Yuan, "Grandma Yuan, don't you mind letting me take the pulse of your other hand again?"

"Hmm!" Old Madam Yuan nodded, and then stretched out her hand.

Zhang Yu stretched out his hand again, pinched Old Madam Yuan's vein, then lowered his head, and said silently in his heart: "Yin and Yang eyes, look!"

With Zhang Yu's silent thoughts, his eyes turned into yin and yang again, and everything in front of him instantly turned black and white!

A few weeks ago, Zhang Yu accidentally discovered that this yin and yang eye can not only see through the shape of ghosts, but can also be used to check the health status of the human body.

A healthy person will be white in front of Zhang Yu's eyes, while a sick person will be gray, and those who have lesions in their internal organs will appear gray or black under Zhang Yu's yin and yang eyes!

And at this moment, under Zhang Yu's yin and yang eyes, Old Madam Yuan's body was grayish-white, and in her lungs, there was a black mass that was rising and falling!

"This is ......" Seeing this cloud of black gas, Zhang Yu's eyes lit up, and he immediately remembered the decades of medical experience from Huo Lao that was fused in his mind.

The accumulation of cold in the lungs is probably caused by the accumulation of bruising over the years and whether the trauma has been healed in time!

At this time, there was silence in the box, Chen Tianming and Yuan Fei did not dare to come out, staring at Zhang Yu with their eyes.

It's just that more than a minute has passed, and Zhang Yu has never said a word, which makes Yuan Fei gradually irritable!

"Can he do it?" Yuan Fei muttered softly.

Although he has Chen Tianming's assurance, to be honest, the young man in front of him really has no way to make Yuan Fei believe it completely!

As if he was responding to Yuan Fei's muttering, as soon as he finished speaking, Zhang Yu straightened up.

When Chen Tianming saw it, he immediately leaned up and asked, "How is it?" Brother Zhang, do you see anything?"

"I see a little bit," Zhang Yu smiled, then turned his head to look at Old Madam Yuan and asked, "Grandma Yuan, did you suffer a heavy blow to the chest a long time ago?"

"Huh?" Hearing Zhang Yu's question, Old Madam Yuan couldn't help but be stunned, and then a bright light radiated from her eyes.

Without waiting for Mrs. Yuan to answer, Yuan Fei on the side muttered dissatisfiedly: "Nonsense! How could my grandmother have been injured?

"Xiao Fei, shut up!" Before Yuan Fei finished speaking, the box remembered Old Madam Yuan's stern reprimand, but it immediately turned into a violent cough!

"What Mr. said is right!" Old Madam Yuan forcibly suppressed the coughing phenomenon, and said in a hoarse voice, "When I was young, I used to compete with others, and I was injured by a palm in the heart!"

"Huh?" Hearing grandma's words, Yuan Fei was dumbfounded!

He really didn't know that his grandmother had such a past!

"Then it's no wonder!" Zhang Yu smiled, with a hint of understanding on his face, "I think Grandma Yuan must have found someone to treat her at that time, but she should not have been able to completely persevere, resulting in the root of the disease not being completely removed!"

Hearing Zhang Yu's words, Mrs. Yuan's originally pale face turned slightly red, and she said: "At that time, I was young, I was afraid of bitterness, and I couldn't drink traditional Chinese medicine, so after I felt that my lungs were not uncomfortable, I secretly poured out all the medicine for the next few days!"

This time, the matter is straightforward!

Obviously, the wound on Mrs. Yuan's lungs was left over from when she was young!

At this time, Chen Tianming on the side suddenly said: "Brother Zhang, since you can see the source of Grandma Yuan's old lung injury, does that mean that you can cure Grandma Yuan?"

"That's right!" Yuan Fei next to him suddenly shouted, and then looked at Zhang Yu, with a trace of eagerness and expectation on his face, only to see him clasp his hands into fists, bowed to Ye Qiu for a long time, and said, "Mr. Zhang, please forgive me for being rude just now!"

"If you can cure my grandmother, I Yuan Fei will be willing to be a cow and a horse for you in this life!"

Seeing Yuan Fei say this, Zhang Yu, who originally disliked Yuan Fei, couldn't help but change his opinion of him!

A grandson who can be filial to his grandmother can't do much worse!

"I need a bed!" Zhang Yu said with a deep groan.

"Huh?" Hearing Zhang Yu's words, Chen Tianming and Yuan Fei were stunned for a moment, and then they were overjoyed!

Obviously, what Zhang Yu meant by this sentence is that he can be cured!

However, there is no bed in this box, but a solid wood sofa.

Zhang Yu saw that the sofa was relatively flat and could be used, so he beckoned Chen Tianming and Yuan Fei together, and slowly moved Mrs. Yuan to the sofa and lay down.

And he had already opened the package he was carrying, and took out the spirit snake needle from Huo Lao's treasure from it!

"Ah, what is this?" Yuan Fei couldn't help but exclaim when he saw the silver needle that looked like a snake's head in Zhang Yu's hand.

"This is called the spirit snake needle, which is a kind of silver needle. Zhang Yu explained, while detoxifying the spirit snake needle, and then came to the sofa.
