In the courtyard, Yun Feng faced his father-in-law Han Tongfu, and this time he was no longer as humble as before.

"This medicine is called penicillin, extracted from mold, if it is extracted well, it is a life-saving miracle drug, and if it is not extracted well, it is a murderous steel knife." Yun Feng was calm.

Pointing to the kitchen room.

"The equipment I use to refine drugs is all in the house, and you can take it away for research." Yun Feng was not afraid of what Han Tongfu could research at all.

Extracting penicillin requires a very rigorous technique.

"Humph!" Han Tongfu snorted coldly: "You kid really can't help me with you?" ”

I saw more than a dozen people quietly surrounding him.

They are all the elite of the Han family, and they are the most capable of the younger generation of the Han family, and they are also the ones that Han Tongfu wants to take to the north to trade.

"Let's go together." Yun Feng was not polite, took two steps back, and picked up the spear from the weapon rack that he usually exercised in the back of the room.

This is his usual occasional workout use.

As the so-called moon stick knife is a lifelong gun, marksmanship must be practiced every day.

If you don't practice for a day, you know, and if you don't practice for a month, everyone will know.

Yun Feng had a spear in his hand at this time, full of confidence.

"Don't waste my time." Yun Feng stared at them, and the gossip of the Yun family under his feet pierced through the clouds and stepped on the gangbu fight, and every step was loud.

More than a dozen children of the Han family looked at Han Tongfu, waiting for an order.

Han Tongfu said resolutely: "Since you kid is looking for death, then don't blame me for being rude." ”

He raised his hand to give the order.

"Don't, Daddy, don't!"

Han Yuyao interrupted his order, and the whole person walked out of the room, with soap foam on his face, and the clothes on his body were not very smooth.

In front of Yun Feng, she opened her arms to block Yun Feng behind her.

Han Tongfu's face was like hoarfrost, and he pinched the corners of his clothes with both hands, forcibly calming himself down.

He said coldly: "Yu Yao, today's medicine is related to the future of the Han family, and I have to get it no matter what." ”

Han Yuyao took half a step back and leaned against Yun Feng's side: "The formula belongs to our Han family, according to the rules of the Han family, Daddy, you can only buy the finished product at cost price, and you can't seek the secret recipe of our seven rooms." ”

"The secret recipe, you tell me the secret recipe?" Han Tongfu gritted his teeth.

"Yun Feng, he is just the son-in-law of our Han family, since he came into our Han family, everything about him is the Han family!"

The son-in-law is like a concubine, and his net worth and life are owned by the Han family.

Han Yuyao said firmly: "Even if it is the Han family, it is also our seventh room." ”

She had no idea of retreating.

Facing Han Yuyao's words, Han Tongfu couldn't refute it, the rules of the Han family were like this.

He could only coax Han Yuyao: "Good daughter, lend the secret recipe to your father first, and then give it to you when the time comes." ”

"No!" Han Yuyao shook her head firmly: "As long as the secret recipe is circulated, it is impossible for it to stay in our seventh room." ”

Han Tongfu really couldn't bear it anymore, he coaxed with red eyes: "Yu Yao, this recipe is to be used by my father to open up the last link in the north, the Han family's planning for this matter has cost all the family's heritage, and it has been planning for more than ten years, and it is impossible to stop because of the secret recipe of your seven rooms." ”

He pointed at Yun Feng: "As long as you hand over the secret recipe, I will allow you to stay with him all the time, and I will never object to you again, and I will restore your seven-room routine every month." ”

With so many conditions, Han Yuyao needed, she looked up at Yun Feng and asked softly, "Is it okay to give them the secret recipe?" ”

It's just a penicillin formula, these people don't know the principle, let alone how to prepare it on a large scale, they can please Han Yuyao, everything is worth it.

Yun Feng almost didn't hesitate: "Okay, I agree, you send someone to study in the seventh room." ”

It's just penicillin, Yun Feng still has many useful things in his mind, and a penicillin is nothing worth paying attention to

Han Tongfu finally relaxed, he was really afraid that Yun Feng would refuse.

Looking at his stubborn daughter, he knew that if Yun Feng didn't agree, Han Yuyao would definitely fight to the end.

"Whew~" Han Tongfu breathed a sigh of relief.

"Wouldn't it be nice to do this sooner?" He couldn't help but complain

At this moment, I heard a voice from the corridor outside: "I don't think it's good, give this kid to our Guangwu Army, I don't want your Han family for the secret recipe." ”

The sound was still far away at first, and gradually it reached the gate.

Dozens of soldiers "hula~" burst in.

Quickly surrounded a group of them, and then an old general came late.

He wore a silver helmet and shiny silver chain mail, and looked heroic.

Han Tongfu turned his head and waited for the old man: "What else do you want?" Yun Feng, he has already agreed to teach you the secret recipe for this medicine. ”

The old general shook his head: "No, I still want him, since he can heal the wounded soldiers, he will definitely be able to heal more injuries." ”

As soon as he opened his mouth, he regarded Yun Feng as a doctor in the army and came to pick him up in person.

Han Tongfu looked back at Yun Feng, and then at Han Yuyao.

He knew that it was impossible for Han Yuyao to agree to let Yun Feng go.

Gritted his teeth: "Old general, my son-in-law is not a doctor, but just a little clever." ”

"No, no, no!" The old general hurriedly shook his head: "It's not a little clever to be able to rescue the person who walked into the Hades Hall with half a leg. ”

"I have seen many soldiers with such injuries in the army, and most of them are much less injured than the boys in this room, but they are all dead without exception." The old general seemed to be recalling something.

"If they could have been treated at that time, they might have survived and become elite soldiers in a hundred battles, so that our Guangwu army would have 100,000 more soldiers."

He looked at Yun Feng's eyes lit up.

Yun Feng had a chill.

Han Tongfu looked back at Han Yuyao: "Yuyao, I have worked hard for my father, and it is really the old general who appreciates Yun Feng." ”

"No!" Han Yuyao refused: "I don't agree, the secret recipes have been handed over, is there still a doctor in your military camp?" ”

"Otherwise, if you take Dr. Ho, he will use medicine. Push the uterus through blood. ”

Dr. He, who was about to retreat and run quickly, was stunned in the wing, stunned.

The old general nodded: "That's right, then take it all away." ”

"Two people, it's better."

As he spoke, a dozen soldiers came out behind him.

"Alas!" Yun Feng sighed, thinking that it could be resolved peacefully.

"Yuyao, you are back." Yun Feng let Han Yuyao lean back, raised the spear in his hand flat, and stared at the soldiers opposite.

More than a dozen people in the Guangwu Army have long been like one, they are united, and the Pu Dao in their hands seems to have become a wall, and several people attack at the same time.

The military formation in front of him was too familiar.

The Northwest Yun family's one-word white cloud array.

Yun Feng was already familiar with this queue, and the spear in his hand stabbed out with a spear.

"Break it for me!"

The crowd is lined up, the head is the tail, the tail is the head, and a group of people are holding Pu knives around you, then there is no chance.

Breaking the game, only when the formation is just rolled out.

Yun Feng's shot, just when they didn't react, rushed directly in front of them.

People move with guns, and guns are also people.

Then a long rainbow ran through the sun.

Blood is spilled, and the shadow of the gun disappears.
