Gu Yanfei was wearing a half-new purple Hu costume and riding outfit, and a black flame whip on her waist. She sat in this simple tea shop with casual posture and a bit casual and casual, as if she could naturally integrate into all environments.

No matter where she is, she can be so leisurely and at ease in the courtyard, as the breeze and flowing clouds, free and free.

It is really not easy for a little girl who has not yet reached the age of hair to have such a demeanor... No wonder that Chu Yi was so obsessed with it and was attracted by it.

Thinking of this, Feng Yang looked at Gu Yanfei with an elder's love and joy, and his expression was gentle, thinking: It was still Chu Yi that boy had vision.

Fengyang drank another sip of warm and burnt barley tea and smiled and said, "I may not have drunk this barley tea for a long time."

"I remember the first time I drank this barley tea when I was a child, I followed my father... and passed through a quagmire with me. I was exhausted. My father carried me out the second half of the way."

"After waking up, my father secretly gave me barley tea with others on his back. At that time, I thought the tea was so fragrant and the best tea in the world..."

She was only five or six years old at that time, but now she is almost seventy.

This person is really unwilling to accept his old age. She is more and more thinking about the past...

Fengyang felt a little sad and a little sad... The sadness of such a person who had passed away lingered in his heart.

Of course, Wei Jiaoniang knew that Feng Yang was referring to Emperor Taizu. Her eyes were burning and she looked at Feng Yang with admiration, with a very warm look.

She heard her grandfather and grandmother talk about a lot about Princess Fengyang. Most of them were about how Fengyang galloped on the battlefield and how Fengyang helped Taizu to stabilize the country. However, this was the first time Fengyang heard about her story when she was young.

Wei Jiaoniang lowered her eyes and looked at the cup of dark brown barley tea in front of her. The burnt aroma of wheat penetrated into her nose and the tea soup was rough.

Wei Jiaoniang picked up the teacup and drank the barley tea that she had just despised.

The tea in the mouth is slightly bitter and burnt, and it tastes a bit sweet and refreshing, and there is a strong barley tea aroma that fills the mouth.

Well, although the barley tastes rough, it has a unique taste.

Wei Jiaoni savored the taste in her mouth, put the cup on the table, and shouted boldly: "Another cup."

The waiter quickly added another cup of tea to Wei Jiaoniang.

Feng Yang put the small blue porcelain jar he just bought on the table and asked in a low voice: "Girl, what's the point?"

Fengyang heard from the emperor and Chu Yi that the penicillium powder was originally presented by Gu Yanfei to Gu Yuan.

Gu Yanfei shook his head.

Since that day, she has taken the so-called Penicillium powder back to her house, she has studied it for many days, but she can't tell what it is.

Two days ago, Chu Yi asked someone to bring the pulse cases of the wounded soldiers in the army to her. Gu Yanfei also looked at it carefully, but still found nothing.

Gu Yanfei didn't feel frustrated. In this vast world, she didn't know many things and means.

Instead, she found it interesting and excited, and said, "From the pulse of those injured, this medicine is indeed magical."

"After the medicine is used, it will take about half an hour to take initial results and begin to reduce fever... Within three days, the condition will basically be stable. In the worse part, it means taking the medicine for two more days."

Feng Yang looked at the small porcelain jar with a slightly slight look on his eyes. After a while of silence, he asked, "Girl, what if it were you?"

"It can be cured." Gu Yanfei nodded slightly, "Heavy-stop muscle talisman, clear fire pill, and supplemented by golden needles, but I must treat it accordingly. I can only save one person at a time, unlike this Penicillium Powder, even an ordinary doctor can use it to save many people."

"However, so far, there are still too few people who have used this medicine, and there are only a dozen cases, and I don't know..."

"I don't know if it works for everyone, and will there be any sequelae?" Feng Yang said.

In ancient times, Shennong Changbai Herbs were found to determine the medicinal properties of a herb, and it is sometimes inevitable. It has summarized some experiences of doctors in taking medicine for thousands of years, especially toxic medicinal materials such as centipedes and aconites. When using medicine, it is necessary to carefully consider the dosage and consider the combination.

A slight difference will make you a huge mistake. If you don’t do it well, it will not save people, but harm people.

Gu Yanfei nodded again and asked casually: "Do you understand medical principles?"

Fengyang seemed to have never heard of it. She seemed to be recalling something, immersed in her thoughts, her eyes became even more erratic, and then said: "It will not work for some people, it will be fatal to some people, and it will be helpless."

After saying this, Feng Yang raised his head from the teacup and met Gu Yanfei's slightly surprised gaze. He seemed to know what she was thinking, and said with a smile: "These are all told by my father."

"My father said that although penicillin is not perfect, the benefits far outweigh the disadvantages."

Wei Jiaoniang had no idea what they were talking about, and she was confused when she heard Feng Yang mention Emperor Taizu, she couldn't help but feel excited.

She also likes to listen to her grandfather and grandmother mentioned the legendary stories of Emperor Taizu when she was alive, and she wished she could see Taizu with her own eyes before she was born more than 20 years ago.

Even if he couldn't understand a word, Wei Jiaoniang was still focused and her eyes were brighter than the sun outside the tea shed.

Fengyang noticed the eyes of the little girl in the Wei family, and felt inexplicably relaxed, thinking with some fun: She is really old. When she was young, she was most impatient to gossip with the girls, thinking that it would be better to pull a few more bows and swing a few more swords with this time, so that fewer people could die on the battlefield.

But now, just looking at these two lively and cheerful little girls, even her mood will be happy.

Just as her father said when he was alive, their generation was bloody on the battlefield for the sake of the eternal blessings of future generations.

The curve of Fengyang's lips was also softer, "My father said that penicillin, as the name suggests, is taken from penicillin. The cyan mold produced by rotting fruits, steamed buns, vegetables, etc. can all be extracted. After cultivation, filtration and other steps, penicillin can be extracted."

"He also said that penicillin should not be taken directly orally, and it will be damaged by gastric acid after oral administration, so it will be ineffective. The best way is to inject it. External application is second best, and there is no way to get it."

"My father only mentioned these few words to me, and in detail, I don't know."

When Emperor Taizu was alive, there were too many novel things he mentioned to Fengyang. Just these few words were just what Fengyang thought about on the way out of the palace for a long time before he remembered it.

"Mold?" Gu Yanfei's face showed a little interest, and he stroked his chin with his fingers, "Can mold be used to treat external evil entering the body?"

interesting.

Gu Yanfei silently chewed what Feng Yang said just now, and was full of energy.

"Miss Nine." A young servant in green trotted towards this side from the city gate. When he ran into the tea shop, he was already breathing rapidly. "Here is here, the prince is here!"

Wei Jiaoniang quickly put down the teacup in her hand, stretched her neck and looked up towards the city gate.

But from her location, there is no one to see.

Unlike Xu Yan, the Marquis of Ji'an at the gate of the city, who could see the end of the official road at a glance, a hundred feet away in front of him, Duke Wei led more than a dozen guards of the Duke's mansions to come here, with horse hooves rumbled.
