"Brother Ye, you, you said you found the cause of my grandfather's heart disease?" Qiao Nana looked at Ye Lengfeng in surprise and asked.

Hearing Ye Lengfeng's words, Luo Wenyu, Li Yun, and Yu Tangchang, who were originally walking towards the door, also turned to look at Ye Lengfeng in disbelief.

As everyone knows.

The time Professor Qiao suffered from heart disease, he fainted at the entrance of the teaching building, and after being diagnosed and treated by many experts at home and abroad, he could not find out the cause of heart disease, and he could only think that the person was old and the function of his organs had declined!

The last time, after Ye Lengfeng revived Professor Qiao in Dade Hospital, he asserted that Professor Qiao had been infected with a chronic poison, a chronic poison that is difficult to detect with ordinary instruments, which attracted great attention from the University of Chinese Medicine and Dade Hospital.

Sure enough, as Ye Lengfeng expected, after being tested by Dade Instrument with the most accurate instruments at home and abroad, it was indeed found that Professor Qiao's blood contained a chronic toxin.

This made countless medical experts, while admiring Ye Lengfeng's superb medical skills and judgment, they were also surprised, why was Professor Qiao poisoned? And where does this toxin come from?

However, no matter what these medical experts think, including the fact that they secretly monitor Professor Qiao's daily life and diet, they have never been able to find the source of this chronic toxin!

Now Ye Lengfeng suddenly said that he had found the cause of Professor Qiao's poisoning and heart disease, and it really scared Yu Tangchang and the others.

Because Ye Lengfeng just now, he sat in the hall drinking tea and chatting with them, and didn't go around.

Everything in the entire hall was visible at a glance, and Professor Qiao did not suddenly appear in any unusual situation, so Ye Lengfeng suddenly said that he had found the cause of Professor Qiao's heart disease, which was indeed a little unbelievable!

"Brother Xiaoye, you said that you found the source of Teacher Qiao's illness, where is it?" Li Yun asked suspiciously.

"yes, it doesn't feel unusual!" Luo Wenyu also spoke.

"Brother Xiaoye, don't you say that the source of Professor Qiao's illness is in this room, right? At that time, when he was sick, we searched inside and out, and we also monitored Professor Qiao's food and clothing all the time, and we didn't find the slightest abnormality! Yu Tangchang looked at Ye Lengfeng in disbelief and said.

In the face of everyone's disbelief and doubts, Ye Lengfeng just smiled and looked at the nanny who was arranging flowers and said:

"Can you bring me the flowers?"

The nanny who was arranging flowers turned around and looked at Ye Lengfeng suspiciously, Yu Tangchang and the others were also a little surprised, thinking that they were not looking for the source of Professor Qiao's illness? What does Ye Lengfeng do when he looks at flowers? It can't be that you're drunk and talking nonsense!

The nanny of the flower arrangement was stunned for a moment, thinking that Ye Lengfeng was a guest after all, so she took the flowers.

Ye Lengfeng took this bouquet of flowers and glanced at it, then sniffed it with his nose, nodded and said to Professor Qiao and the others:

"The problem is with this bouquet!"

"What? Having a problem with this bouquet of flowers? ”

"Wouldn't it? What's wrong with a bouquet of flowers! ”

"Brother Xiaoye, are you saying that this flower is poisonous? Probably not! Yu Tangchang also glanced at the flower in Ye Lengfeng's hand, shook his head and said.

Seeing that Yu Tangchang, Luo Yuwen, and Li Yun were all questioning, and Professor Qiao was also not very convinced, Ye Lengfeng smiled indifferently.

"Brother Ye, this is an ordinary tulip, if it was a poisonous flower, we would have discovered it a long time ago!"

Qiao Nana also reminded Ye Lengfeng in a whisper, afraid that he would lose face in front of a Chinese medicine expert like Yu Tangchang, and those previous praises would probably be greatly reduced!

Ye Lengfeng smiled and nodded at Qiao Nana, then looked at Professor Qiao and asked:

"Teacher Qiao, do you feel particularly sleepy after dinner every day? It's different from the sleepiness that I usually feel during the day, but I really want to sleep. ”

"It seems like yes, but a lot of older people do!" Professor Qiao spoke.

"Then let me guess, every time Mr. Qiao, you are most sleepy and want to sleep, it is when the nanny cleans up the dishes and chopsticks and arranges flowers, right?" Ye Lengfeng asked with a smile.

"You...... How do you know? Professor Qiao asked, shocked.

"Brother Ye, how do you know? Do you still know how to tell fortunes? Jonana also asked with her mouth wide open in shock.

You must know that Ye Lengfeng has just returned to the city, and he has not had any contact with Professor Qiao and Qiao Nana before this, let alone come to Professor Qiao's house as a guest!

Although Professor Qiao's clothing, food, housing and transportation were monitored and protected after he fell ill, no one really knew and paid attention to things like this when Professor Qiao went to bed and when he was sleepy.

"That's right, Mr. Qiao, the reason why you got chronic poison and had a heart attack was because of this bouquet of flowers!" Ye Lengfeng said seriously.

"Yes...... But this is obviously a very ordinary tulip? ”

Yu Tangchang was really a little puzzled, thinking to himself how could an ordinary tulip be poisonous, if it was to cause people to have heart disease, it would be even more impossible!

Not only Yu Tangchang, but also Luo Wenyu, Li Yun, Qiao Nana, and Professor Qiao himself were all very surprised, and it was really a little hard to believe Ye Lengfeng's words.

Ye Lengfeng looked at the people present, and finally turned his gaze to Yu Tangchang, an authority in the field of traditional Chinese medicine, and asked:

"It's a very ordinary tulip, but what if the two flowers are mixed for a long time, tulips and nightshades?"

"It will lead to insomnia, dreaminess, poisoning, chest tightness and shortness of breath, dizziness, and in severe cases, it will lead to systemic organ failure...... However, this is just a bouquet of tulips, not mixed with nightshade! Yu Tangchang frowned and said.

"Yes, Brother Xiaoye, these two flowers of tulips and nightshade can't be mixed together, not only those of us know it, but even ordinary people know it, and Professor Qiao's entire courtyard can't find nightshade inside and out!" Luo Wenyu also spoke.

Ye Lengfeng didn't speak, took this bouquet of tulips that seemed to be very ordinary, walked under the light, and shook it lightly with his hand, and the pollen on the tulips fell on the glass coffee table.

"Brother Xiaoye, do you want to say that there is something wrong with this pollen? But there's nothing wrong with that! Li Yun looked at Ye Lengfeng suspiciously and said.

Ye Lengfeng smiled slightly and said to Qiao Nana:

"Nana, you go and get a glass with water, and now it's time to witness the miracle......"
