There are not many ingredients in malt milk essence, since it can be processed into that kind of granule, it should not be difficult for Chinese patent medicine to be processed into that kind of granule.

As for how to make the granules sweeter, then it is necessary to do a fusion test with the sweet ingredients and Chinese patent medicines, and select the ingredients that do not affect the efficacy of the medicine and add them.

Lei Yongan's mind turned slightly, and his heart became brighter.

Perhaps, this method of the little girl is really feasible, maybe you can also make some Western medicine into granules suitable for children!

"Zihan, your idea is too good, you say, how much are you going to sell this idea to me?"

He had already said that he would buy her idea, so he would never break his word.

Zihan shook his head quickly, "I don't want money, this guarantee is to exchange my idea for you." ”

She didn't come up with the idea of making pills or granules, and she was really embarrassed to ask for money!

"No, the guarantee is a guarantee, the idea is the idea, and only if you buy it, can it be regarded as our pharmaceutical factory."

When Lei Yongan said this, his eyes looked at Grandpa Lin intentionally or unintentionally.

Grandpa Lin immediately understood what Lei Yongan meant.

The corners of Grandpa Lin's mouth moved slightly, "Director Lei, this is just a little girl's momentary thoughts, and you can pay for it there." ”

Grandpa Lin's eyes looked at Zihan, and smiled dotingly at Zihan, who seemed to be a little unclear, "Zihan, you can't tell others about this idea in the future, from today on, this idea is Director Lei, do you understand?" ”

Zihan seemed to suddenly realize, and nodded solemnly, "I know, Director Lei exchanged the guarantee for my idea, then the guarantee is ours, and the idea is Director Lei." ”

Grandpa Lin nodded, sighed softly in his heart, and rubbed her head dotingly, it seems that he will have to bring Zihan out in the future, so that she can see the world more.

"Doctor Lin, what do you think of my idea of giving five hundred yuan to buy Zihan?"

Grandpa Lin hurriedly waved his hand, "Director Lei, it's just a child's blind idea, you really don't have to give money, please rest assured, I won't let her talk nonsense after I go out." ”

Lei Yongan hesitated for a moment, but hurriedly took the pen and paper and looked at Zihan.

"Zihan, can I ask you to write a letter of guarantee as well?"

The expression on Grandpa Lin's face froze, and after a moment, he sighed faintly.

"Zihan, you can also write a letter of guarantee!"

In order to reassure Lei Yongan, although Grandpa Lin felt a little uncomfortable, he still decided to let Zihan write a letter of guarantee.

"Grandpa, this is as it should be, Director Lei gave me a letter of guarantee, and I should do the same, and I should be honest in business."

Zihan happily took the pen and paper, lay on the table and tried to learn Xiao Zihan's handwriting and write.

Seeing her relaxed expression, the unhappiness in Grandpa Lin's heart dissipated in an instant.

Also, in the future, they will grow their own medicinal herbs, and they will inevitably deal with pharmaceutical factories, and it is appropriate to be honest.

Zihan writes very carefully, and occasionally raises her head to think for a moment.

When Lei Yongan saw the handwriting written by Zihan, although it was a little crooked, but the content was extremely detailed, the corners of his mouth couldn't help but curl.

"Doctor Lin, your granddaughter is not simple!"

Grandpa Lin took the letter of guarantee handed over by Lei Yongan with a smile, and his eyes couldn't help but light up.

In addition to the initial guarantee, Zihan wrote a letter of guarantee, and there are several additional items below, one of which is that if she violates their agreement, she will compensate the pharmaceutical company for its losses.

In addition, she writes that she will come and try the taste of the new medicine for free and give her opinion.
