In the end, Yun Xi thought of a particularly clever method. She grounded these expensive Chinese herbs into powder, then added milk powder and some icing sugar into the powder to make it look like a tonic for the old man to take.

In this era, although milk powder was not cheap, it was still much cheaper than Chinese herbs like ginseng and lingzhi. This made the Old Master feel less burdened.

“Grandpa, drink it.”

Yun Qiao put the cup on the head of the old man’s bed and handed it to him.

“What kind of tonic is in this cup?” The Old Madam asked curiously.

“This is milk, which can supplement nutrients,” Yun Qiao answered with a smile. He did not plan to tell the Old Master and the Old Madam the truth about this milk powder.

The Old Madam was a little surprised to hear Yun Qiao’s answer.

Although milk powder was not something that was often drunk in their house, in the Old Madam’s impression, milk was generally white. However, the color of this cup of milk clearly had a yellowish-brown feeling.

The Old Madam’s first impression was that the younger generation had added ingredients to this bag of milk powder. They must have been afraid that the milk powder would be especially expensive, so they added other cheap things to this bag of milk powder, which caused the milk to change color.

Sure enough, one did not like anything that they saw around a child that they did not like. If this cup of milk had been brewed by someone from Yun Gang’s family, the old lady would not have thought so much. However, it was Yun Shan’s family who prepared it, so the Old Madam felt uncomfortable.

The Old Madam thought as she brought the milk over. The color inside was indeed yellow-brown, and the smell was not very pleasant. The Old Madam frowned and was a little annoyed.

“Old nan, didn’t you notice that the taste of this milk is a little off? The color is also a little off. I’m afraid that Yun Shan’s family was afraid that you would spend too much money drinking the milk, so they added other things into this milk to fool us?”

The Old Madam could not keep her mouth shut, so she still spoke her inner thoughts to Old Master Yun.

Old Master Yun was a little surprised when he heard what the Old Madam said. However, deep down in Old Master Yun’s heart, he didn’t believe that Yun Shan’s family would add other ingredients to the milk.

“Old lady, don’t frame the child. This is our biological son. Do you think he can harm me? Besides, this milk isn’t expensive. Think about it, Yun Shan’s family can be considered a well-off family now. You also said that they spend a lot of money on meat at the dinner table. Why should they add anything to this bag of ordinary milk powder? If you don’t have evidence, don’t talk nonsense. When the time comes, you’ll break the hearts of the younger generation.”

The Old Master was a sensible person. When he heard the Old Madam’s immature thoughts, he immediately reprimanded her.

Although the Old Master’s words were not pleasant to hear, the Old Madam did not dare to argue with the old man.

However, the Old Madam was still very suspicious in her heart and prepared to look for evidence herself. The old lady left the master bedroom and went to the kitchen. She walked around the kitchen stove twice but did not find any traces of milk cans or bags.

Finally, the old lady came to the cupboard and finally found traces of a bag of milk powder in the cupboard.

However, this bag of milk powder was just ordinary milk powder that Yun Xi had bought for Chen Li. The old man’s expensive bag of milk powder had to be prepared and brought home by Yun Yang from the medical center every day, so of course, it could not be found at home.

The old lady opened the bag of milk powder and saw that it was indeed milky white milk powder. It did not appear yellowish-brown in color.

The old lady used her forefinger to dip a little milk powder in her mouth to taste it. It was a very sweet milk taste, and the taste was different from the one she smelled in the cup today.

The Old Madam thought to herself, this little daughter-in-law is indeed a sly one. In order to save a little money on milk powder, she added other things to the Old Master’s tonic.

An idea came to the Old Madam’s mind.

Chen Li’s body had recovered a lot after a period of adjustment. In order not to affect the children’s normal study and life, Chen Li told her family that her body was not a big deal and that she should go out for a walk. So the task of buying vegetables naturally fell to Chen Li.

Chen Li went out to buy vegetables at the right time as usual. This time, she restrained herself and did not buy too much meat.

After all, if she offended the Old Madam and she started to scold people at the dinner table, no matter how delicious the meat was, everyone would not be able to swallow it.

However, on the way home today, Chen Li felt that the neighbors around her had been looking at her, and they were mumbling something.
