Mr. Zheng looked at the two of them and said in surprise: "A Qing, it turns out that you and Yanyan, you know each other!"

Fate is such a wonderful thing!

Old Mrs. Zheng said: "Yanyan is the miracle doctor who cures Xiaodie!"

"So that's how it is." Old Master Zheng nodded.

"Grandpa Zheng, Grandma Zheng, come in quickly." Ni Yan turned sideways and let the two old men go in.

The courtyard is very beautifully designed, and it is full of vitality even in winter.

Mr. Zheng and Mrs. Zheng were all amazed in their eyes.

A little fat guy ran towards this side quickly, "Sister! Sister!"

Ni Yan reached out and picked up the fat man, "Yunyun, call him grandma."

Xiao Niyun said obediently: "Grandpa, grandma."

Old Mrs. Zheng smiled and said, "Little Yunyun has grown up so old. When she saw her last time, she couldn't speak. In a blink of an eye, she would run away."

Mr. Zheng looked at Xiao Ni Yun with some confusion.

My eyes suddenly became slightly red.

I don’t know if I am eager to miss my daughter, but he always feels that the little Ni Yun in front of him looks exactly the same as Zheng Tingting when he was a child.

"Can I give me a hug?" Mr. Zheng looked at Ni Yan.

"Yes." Ni Yan nodded.

Xiao Ni Yun is very vigilant. If she were normal, she would definitely not let strangers hug her, but today, when Mr. Zheng picked her up, she was very happy.

Old Mrs. Zheng also looked at Old Mrs. Zheng in surprise. You know, Old Mrs. Zheng doesn’t like children very much.

When Zheng Xianjing was a child, he never reached out to hug her.

"Grandpa." Little Ni Yun reached out and grabbed Mr. Zheng's beard.

"Why."

"Grandpa, what's this?"

“This is a beard.”

"Grandpa, what's that?"

“That’s a flower.”

"Grandpa is stupid, that's fafa."

Old Mrs. Zheng almost thought she was having hallucinations.

This old man was so abnormal today, just like a different person.

"Yanyan, who is here?" Ni Cuihua and Shangguan Dehui walked out of the house.

"Grandpa Zheng, Grandma Zheng, this is my parents." Ni Yan took the initiative to introduce.

Shangguan Dehui knew Mr. Zheng and Mrs. Zheng, "Uncle Zheng, Aunt Zheng."

"Dehui!" The old couple looked at Shangguan Dehui in surprise.

I had heard that Shangguan Dehui had remarried for a long time, but I didn't expect that he would marry Ni Yan's mother.

"Two old men, hurry into the house and sit down." Ni Cuihua said.

"Okay! OK!" Old Mrs. Zheng and Old Mrs. Zheng nodded.

After entering the house, Ni Cuihua and Shangguan Dehui were busy pouring tea and snacks for the two old men.

Ni Cuihua said: "It's too late. Dehui, go to work quickly. I'm at home!"

Today is Monday, and Shangguan Dehui has classes in the morning.

"Okay." Shangguan Dehui nodded, "Then I'll go and say hello to Uncle Zheng Aunt Zheng."

After saying hello to Mr. Zheng, Mrs. Zheng, Shangguan Dehui left.

Mr. Zheng kept holding Xiao Ni Yun, "Yanyan, your grandma Zheng and I have been feeling a little uncomfortable recently, especially your grandma Zheng. They have been coughing for many years and have not been cured. Please show her first."

Ni Yan nodded slightly and reached out to take the pulse of Old Mrs. Zheng.

She frowned slightly, her eyebrows and eyes were serious, and the crystal light reflected a cold light in her eyes, and her appearance was very eye-catching.

After a moment, she let go of the old Mrs. Zheng's hand and asked, "Can I ask what medicine you have been taking during this period?"

Old Mrs. Zheng thought for a while and then said, "I don't know what the name is, it's just a cough-relieving effect."

"It's Chopterlin and Ampicillin." Mr. Zheng replied.

Old Mrs. Zheng looked at Old Mrs. Zheng in surprise. She didn't expect that Old Mrs. Zheng could still remember what medicine she took silently.

Ni Yan frowned slightly, "Is it just the only thing about Chopin and Ampicillin?"

"Does tonics count as medicine?" Mr. Zheng continued.

Ni Yan nodded, "It's also worth it."

"She usually also has some tonics such as ginseng chicken soup, Cordyceps sinensis, deer antlers, etc." Mr. Zheng said.

Ni Yan continued: "Actually, Grandma Zheng's cough is not a big problem, but strangely, the medicine she took over the years is like not taking it. I suspect it is related to eating food normally. Some foods are incompatible. Not only can the medicine lose its corresponding effect, but it will also backfire. Over time, a layer of slow toxin that harms human health will be deposited in the body."

"Yanyan, do you mean, are you Grandma Zheng poisoned?" asked Old Master Zheng.

"Yeah." Ni Yan nodded slightly, "It can be understood that Grandma Zheng's cough has been going on for ten years, and it has been a while since the middle of the disease. It must have suddenly become serious since last year, right?"

"Yes." Old Mrs. Zheng nodded, "It started last year."

Ni Yan said again: "So have you changed your diet since last year?"

Old Mrs. Zheng said: "In addition to three meals a day, I can drink some tonics, which are what your Grandpa Zheng just said."

Mr. Zhao said anxiously: "Then is your Grandma Zheng serious now?"

Ni Yan's expression was a bit serious, "It's not serious, but it's not serious. If the toxins in Grandma Zheng's body are not removed in time, once they deteriorate, they will be in danger of life at any time."

Mr. Zheng's face turned pale, "Do you have a way to detoxify Yanyan?"

"Grandpa Zheng, don't worry, there will be antidotes in this world. Fortunately, Grandma Zheng came here in time. If it was a little later, it would be difficult to solve it." Yuluo, Ni Yan continued: "It's three parts poisonous. During this period, don't take those tonics again..."

"Okay, then I'll bother you Yanyan." Old Master Zheng nodded and breathed a sigh of relief.

Ni Yan took out a small porcelain bottle and handed it to Mrs. Zheng, "Grandma Zheng, you should take this detoxification pill first, and then avoid tobacco, alcohol, spicy food, and raw and cold food during this period. Well, don't take the two medicines of Cough Trillin and Ampicillin again."

"Okay." Old Mrs. Zheng solemnly took Old Mrs. Zheng and took Ni Yan's words in her heart.

After reading it for Mrs. Zheng, Ni Yan took the pulse of Mr. Zheng again.

Mr. Zheng’s pulse was very stable, but under the calm, there was a crisis hidden, and his internal organs were slightly corroded.

If you explore carefully, you will find that his symptoms are somewhat similar to that of Mrs. Zheng.

If the toxins in Mrs. Zheng's body are caused by food restraint, what about Mr. Zheng's?

How could these two old people be poisoned at the same time?

There seems to be something tricky in this.

After a moment, Ni Yan let go of Mr. Zheng's wrist, "Grandpa Zheng, have you been drinking tonics recently?"

"Yes." Mr. Zheng nodded.

During this period, Zheng Lingling would make various tonic soups for him and Mrs. Zheng every day.

"Then who is simmering this tonic?"

"It's my daughter." Mr. Zheng replied.

Ni Yan continued: "Grandpa Zheng, you have been sleeping poorly recently and are also accompanied by tinnitus and dizziness?"

"Yes." Mr. Zheng continued nodding.

"Your body also has a layer of toxins, which is somewhat similar to Grandma Zheng's situation." Ni Yan told the truth.

Mr. Zheng frowned and suddenly thought of the key point, "Is it because you, Grandma Zheng and I, both ate compromising food at the same time?"

After all, what he and Mrs. Zheng usually eat the same food.

"There is also a possibility," Ni Yan continued: "But the possibility of artificial poisoning is not ruled out."

Artificial poisoning!

Hearing this word, Old Ye Zi and Old Mrs. Zheng both turned pale.

"Yes, it probably won't be human poisoning." Old Mrs. Zheng said.

In the Zheng family, who would poison them?

The servants have no grudges and no grudges against them, and they will definitely not be poisoned.

Then there is Zheng Lingling.

But Zheng Lingling is their daughter whom they have raised for more than 30 years. Although she is not her biological child, she is better than her biological child.
