Qi Yan followed Kang Danyang around the iron shop of Kang's family, and finally saw the field sword he customized last time.

Field swords are also a kind of military daggers.

Its main function is to fight close range and assassinate and injure the enemy.

It can also be used to overcome obstacles and open up shrub roads.

The serration on the back of the knife can cut off small branches and set up tents; a blood groove is also opened on the side, which can be used to slaughter wild animals and dig up stems and fruits.

Therefore, in Qi Yan's era, military daggers were still indispensable weapons for soldiers.

The biggest difficulty in this creation lies in the position of the knife grip.

Qi Yan didn't want to be unable to hold the knife because she had sweat in her palms. In the end, she chose to ask the Kang family to use nanmu that is not easy to deform when exposed to water as a sheath outside the handle of the knife.

Nanmu is expensive in the Great Yan Dynasty.

Because Qi Yan has high requirements, it is relatively difficult to build.

But when Kang Danyang handed the field knife to Qi Yan, Qi Yan took the weight and felt very good.

The sharp blade is a good knife!

I have to say that Kang’s iron shop is really amazing. They just draw a drawing by themselves, but they can make a knife mold and then make it one by one!

Qi Yan is really optimistic about Kang's iron shop in this skill.

Kang Danyang said while holding the knife: "The first batch of field knives have been completed, and fifty are still being produced. At most ten days, you can hand them all over to the Duke of Dingguo Mansion."

"good."

Qi Yan nodded, saying that there was no problem.

Just while she was still looking at the knife, a little girl of seven or eight years old rushed in, crying obviously, "Sister, my nanny is vomiting blood! Go and see her!"

"What?!"

Kang Danyang was so scared that he didn't care about Qi Yan and hurried to the backyard.

Qi Yan did not continue to look at the knife anymore, followed behind them and went to see Mrs. Kang.

The incident of Mrs. Kang vomiting blood has not alarmed Old Man Kang, so Kang Danyang and others are the first to rush into the room.

After Kang Danyang entered the room, he hugged Mrs. Kang on the bed. Seeing the blood on the spittoon bowl, he looked distressed, "Ah Mi! Ah Mi, how are you?"

Old Mrs. Kang leaned weakly on her granddaughter's shoulders, and her nose was stained with red blood, and her voice was hoarse and ugly, "I... it's okay."

As soon as Qi Yan entered the room, her left eye opened and she checked the physical condition of Mrs. Kang.

——Female, the age of the bone is about forty-six years old.

——Hemorrhage occurs in the respiratory organs below the throat, and hemoptysis is discharged from the mouth through coughing.

——The condition is occult hemoptysis, which causes nasal bleeding due to bronchodilation.

——Summary: Hemoptysis caused by bronchial disease.

Qi Yan secretly breathed a sigh of relief when the data scanned the result of Mrs. Kang.

Fortunately, it was hemoptysis caused by bronchial disease. If it was a lung disease, if it was a cardiovascular disease, I am afraid that with the medicinal herbs she now has, there is really no way to cure the old lady Kang.

This time, Mrs. Kang pleated hemoptysis probably because her bronchial disease was not well treated, or she accidentally took a prescription to aggravate her condition, which made the condition worse.

Qi Yan took a step forward and looked at Kang Danyang, "Sister Danyang, can you show me the prescription Grandma Kang usually drinks?"

"Xiao Ning, show Sister Yan the prescription that Ah Mi usually drinks."

Kang Danyang nodded, not rejecting Qi Yan's request.

The little girl, who was seven or eight, walked to the cabinet beside her, opened the drawer, picked out a piece of paper, and handed it to Qi Yan.

Qi Yan looked at it carefully and frowned, "Where did this prescription be prescribed?"

"What's wrong with the security guard? Is there any problem with the prescription?"

Kang Danyang didn't know why Qi Yan asked this, but she could tell that Qi Yan's face was a little wrong.

Qi Yan put the prescription in her sleeve and said to Xiaoning, "Xiaoning, go and get paper and ink."

"good!"

Xiao Ning was very quick to prepare paper and ink quickly.

Qi Yan wrote two prescriptions. After the ink was dried, she gave Xiao Ning another five taels of silver and asked her to go to the medical hall to get the medicine.

Xiaoning took the prescription and silver and looked at Kang Danyang blankly, not knowing whether to go.

Seeing Xiao Ning's hesitation, Kang Danyang gritted his teeth and said, "Why are you still standing there? Why don't you go quickly?"

"Okay, I'll go here! I'll be back in two quarters of an hour!"

Xiao Ning put the prescription and silver into his arms and ran all the way.

Qi Yan walked to the front of Mrs. Kang, who had fainted.

Qi Yan said to Kang Danyang, "I know a little acupuncture technique. It was taught by the witch doctor who cured my cousin. If you can trust me, I will give Grandma Kang acupuncture to relieve her pain. She has been coughing for a long time and hurt her throat. If she doesn't treat it well, even if her illness is cured, her throat will be ruined."

"I believe in Sister Yan!"

Kang Danyang did not hesitate at all. She knew that Qi Yan had no malice towards their family.

Even the business provided by the Qi family is the only business they can persist in the capital.

Grandpa Qi is a very good person. Every time he comes, he will bring a lot of delicious food to the Kang family.

Grandpa said that you must be calm when dealing with the Qi family!

Qi Yan asked Kang Danyang to put Grandma Kang on flat, and then she began to apply needles to Grandma Kang.

She now carries silver needles with her when she goes out.

Qi Yan lost Wu Ling, but the silver needle she carried can not only save people, but also kill people!

Qi Yan has not yet killed anyone, because she remembers the sect rules of the master: either do not kill, or kill the entire clan, leaving no future troubles!

After giving Grandma Kang an injection, Grandma Kang's breathing gradually became smooth and powerful from the beginning.

After receiving the injection, Xiaoning also came back in time.

Qi Yan picked out a pack of medicine from it and handed it to Kang Danyang, "Can you make Chinese medicine?"

"meeting."

"Remember, boil it slowly over low heat, and boil three bowls of water into one bowl of water."

"good."

Kang Danyang knew it, so he hurriedly took the medicine bag and went to boil the medicine himself.

When Xiao Ning came back, sweat beads from her forehead kept flowing, and her little face turned slightly red, which was hot.

Qi Yan told Xiao Ning to get a teapot, then smash the other pack of medicinal materials he bought bit by bit, then tie it up with a piece of cotton yarn, throw it into the teapot, and inject hot water into it.

When we finished all this, Kang Danyang came back.

Qi Yan poured out the water from the teapot and handed it to Kang Danyang and Xiaoning, "Drink and see."

"Ah? Give us a drink?"

Kang Danyang and Xiaoning were both shocked.

Qi Yan nodded, "You live next to the iron shop all year round, and the hot temperature is also subtly affecting your body. You can drink it first. If you think it tastes good, you can buy it in the medicine shop every few days, and then brew it to drink it to nourish your body. Xiao Ning, how did I deal with the medicinal materials just now, do you remember?"

"Remember!"

Xiaoning nodded repeatedly, indicating that he remembered it.
Chapter completed!
