In late September, Old Man Feng suddenly sent a message to Feng Tiandong to come to the old house in the countryside immediately.

Feng Tiandong was startled, he didn't know what was going on at home, he was afraid that his parents were ill, so he hurriedly said hello to Ishikawa Ichiro and quickly rushed to the old house in the countryside.

Not long before, after the meeting held by Fukuyama Sifu, Feng Tiandong left a letter to Liu Baosheng in the dead mailbox: asking Liu Baosheng to tell the enemy engineering department of the military region as soon as possible, and according to the information of all parties, he had basically determined that the inner line sent by Chang Fei was hidden in the first division.

At the same time, it is reminded that in the near future, the enemy may do some investigation of this inside line to confirm whether he is safe. It is hoped that the military region will take advantage of this opportunity to try to discover some clues.

Because he was in a hurry and the time was inconvenient, Feng Tiandong didn't bother to say hello to Liu Baosheng, and came to the old mansion in a hurry. Ignoring the other people in the family who greeted him, he broke into his father's study in ignorance, but saw that the old man was drinking tea, sitting on a recliner and reading a book, without any anxious expression.

"Daddy! What's the matter, calling me here in such a hurry, it scared me a lot, I thought something big happened at home. Feng Tiandong gasped and said without complaints.

The old man looked at him with a smile, and rarely burst into a foul language, scolding: "Phew! You little bunny, you can't hope for something good! There was also a big incident at home. Naturally, there is a reason to call you here, what's the matter? I can't call you yet? You're not happy yet? ”

"Hey, hey! How can you! Of course I look forward to the good at home," Feng Tiandong said with a hippie smile, then sat down next to his father, poured himself a cup of tea, and drank it dry in one gulp, calming down the impatience of the hurried arrival.

"Dad, is my mother okay!"

"Excellent! You go see her in a moment. ”

The two of them laughed a few words, and the old man gradually restrained his smile, took out two small porcelain bottles, handed them to Feng Tiandong, and said: "Tiandong, do you remember, when you asked me what I was doing, I said I wanted to surprise you, and now it has been completed, this is it." ”

Feng Tiandong's face was full of joy, and he didn't know why, so he took the porcelain bottle and opened it to take a look, and saw that there were three pills in a porcelain bottle, and half a bottle of medicinal powder in a porcelain bottle.

Seeing Feng Tiandong looking at the porcelain vase in a daze, Old Man Feng said kindly: "Tiandong, when your grandfather and I asked you to learn Chinese medicine, you didn't listen, you had to learn some Western medicine, you, you know the breadth and profundity of Chinese medicine, these are the proof." ”

Then, the old man's face gradually became serious, and he explained to Feng Tiandong carefully.

These two things are the research results of Mr. Feng for a long time, a pill, a kind of powder, the pill is taken internally, the powder is applied externally, hemostasis, analgesia, and anti-infection have miraculous effects, from the perspective of the old man's experimental efficacy, the anti-infection effect is at least not worse than sulfonamides.

This prescription, Feng Lao has been alone for more than half a year of animal experiments, and even, the old man has done several experiments on himself, the efficacy is completely confirmed, the combination of these two drugs, for all kinds of external trauma of the body, including gunshot wounds, knife wounds have excellent efficacy, can resist wound infection, accelerate wound healing.

The pill was named "Zhixiao Dan" by the old man, and the medicinal powder was named "Zhixiaodan".

This prescription was provided by Mr. Feng on the basis of the incomplete prescription of Yunnan Baiyao in his previous life, and after Mr. Feng's multi-faceted differentiation and combination experiments, he made great achievements.

Old Man Feng really gave Feng Tiandong a big surprise, an absolutely shocking surprise.

After the surprise, Feng Tiandong fell into a long period of contemplation.

If this is in a peaceful and prosperous era, with this prescription, the Feng family will rise and jump again and become the top family admired by the world, and the old man Feng will also be written into the history of traditional Chinese medicine, but now is the time of war, and Feng Lao's prescription is a medicine urgently needed for the war, how to use this prescription is to test the mind of the father and son for two generations.

Looking at the old man next to him who closed his eyes and recuperated, looked at the prescription in his hand, and then thought about the scene he saw when he went to the Eighth Route Army Field Hospital for surgery last time, and thought about the wounded who lacked medical treatment, Feng Tiandong decided after serious thinking: Sacrifice!

However, will Elder Feng agree to do this? After all, this is the result of the old man's painstaking efforts.

Feng Tiandong stood up, walked behind the old man, and asked tentatively while massaging the old man's neck and shoulders with both hands: "Dad, how are you going to deal with this 'Zhixiao Dan' prescription?" ”

"Child, I'm old and don't want to take care of things anymore, leave it to you, you can decide for yourself." Old Man Feng didn't open his eyes and said without hesitation.

"Can I do whatever I want?"

"Of course!"

"Dad, I want to dedicate him to the Anti-Japanese War Organization!"

"Hahaha! Good! Good! Good boy, Dad really didn't need to mistake you! You are the pride of our Feng family! Old Man Feng opened his eyes, patted his thigh, and said with relief.

"Dad, but in this way, don't say that our Feng family can't make money, and we can't even let others know that this is your invention, whether it's fame or profit, we won't get it, and it may even bring some danger to our Feng family."

The old man waved his hand and said: "Tiandong, you don't need to say it anymore, I have lived for such an age, I don't understand anything, since I said that I will leave it to you at your disposal, that is to trust you, you are my Feng Houpu's son, I believe in you, you will not let me down." ”

Feng Tiandong nodded and took the opportunity to say, "Dad, I said just now that after I donate the prescription, our family will face a certain danger. The world is unpredictable, Dad! You and my mother should go to Chongqing in the rear first. ”

"Little bunny, I told you not to mention this again, you forgot!" Old Man Feng glared, scolded, and raised his hand to slap Feng Tiandong's head.

Feng Tiandong shook his head helplessly.

………………

The stakes are very high, and Feng Tiandong does not dare to slack off.

The old man has the old man's experimental methods, Feng Tiandong has been influenced by Western science, in order to confirm the efficacy of "Zhi Xiao Dan" and "Zhi Dissipation", he wants to do the simplest comparative test in line with Western science.

Feng Tiandong couldn't care about the battle in the second phase of the "Hundred Regiments War" that had begun, so he arranged for Liang Ying to go back to Guhuai, and asked Ishikawa Ichiro for a period of leave on the grounds of a sudden serious illness.

During his recuperation, Ishikawa Ichiro was suspicious of Feng Tiandong, and once assigned another liaison translator, Qiu Guang, to visit him in the countryside.

Of course, guarding the divine doctor Old Man Feng, plus Feng Tiandong himself is also studying medicine, it is still very easy to deceive Qiu Guang's mallet, not only that, Qiu Guang also brought Ishikawa Ichiro the news that Feng Tiandong was very seriously ill.

In fact, Qiu Guang couldn't be happier when he saw that Feng Tiandong was seriously ill, and he wished that he would die of illness, so that he could enjoy better treatment in the secret service, and he was very envious of Feng Tiandong's status in front of the Japanese.

The small animals in the family suffered, not only them, but also Erliang and Shishi, plus Feng Tiandong himself, also became the object of drug tests, and each of them had several wounds on their arms.

In this way, after half a month of simple comparative experiments, the powerful efficacy of "Zhixiao Dan" and "Zhixiaodan" can be basically confirmed.
