It's night, Ganquan Palace.

The opportunity for more than 30 siblings to have dinner together is really rare, and many of them are even meeting for the first time, and they can't even name them, but they will all go their separate ways after a few days.

Of course, Yingyu, as a traverser, has no sense of belonging and closeness, but the etiquette is in place.

At the last gluttonous feast, the princes were not qualified to participate, and they were full of curiosity and anticipation for the delicious food.

As the eldest son, Fusu divided five by two, and then sat down with a group of younger siblings.

In the elegant room of the side hall, in addition to Fusu, Gongzi Gao, Jianglu, Hu Hai, and Yin Yan, there are also Gongzi Leopard who rushed to the military reclamation, and Gongzi Zhu Shen County did a small history.

There are exactly eight people at one table, but they represent eight different directions.

Fusu first gave Yin Yan a beating on his head and face.

"A princess has her own princess's mansion, why should she live in your ninth brother's palace? What kind of system? ”

"Brother Jiu is not an outsider, why can't I live here with Brother Jiu?"

Yin Yan was all mouthful, crying, aggrieved but very stubborn, "Here Langtai Water Pavilion, fairy spirit fluttering, it is rumored that the ancestor Mi Bazi, including grandmother Zhao Ji have lived here, I want to be contaminated with fairy energy here!"

Besides, Brother Jiu and I can learn a lot, and my father also knows that I live in Ganquan Palace, so he has no objection! ”

"You ......" Fusu's tone froze, as if unexpected.

"Big brother, I'll protect Yin Yan, she's very happy here!" Yingyu stepped forward to relieve the siege, and then changed the topic, "Come, let's have a drink?" ”

Unconsciously, Yingyu's status in the hearts of her sisters has quietly undergone great changes, and Fusu is no longer entangled in this matter.

……

"The ninth brother recommended me to the wild land of Lingnan, and it is said that poisonous insects and miasma are everywhere, like a demon cave."

Fusu looked as a matter of course, "You can't ignore it, is there a good way to deal with the miasma of poisonous insects?" ”

"Hehe, big brother, this is lying to me. Became the governor of the three counties, is this a cheap and still a good job?! ”

The corners of Yingyu's mouth seemed to smile and said, "Or, I'll talk to my father and the emperor, and our brothers will change?" ”

"How's that going to work? Because of the harsh environment, the eldest brother is the one who will not let go! ”

Fu Su raised his eyebrows, looking righteous and awe-inspiring, but there was a hint of cunning at the corner of his mouth, "Brothers and sisters, half of them are willing to rush to Lingnan with me, if they make a mistake, I'm afraid you won't be able to explain, right?" ”

"Poof......

Yingyu stroked her forehead with her hand, looking loveless, and had a headache for this eldest brother, "What does this have to do with me?" ”

"Hehe......"

Fusu urged narrowly, "The courtier's brother patted his chest in front of the courtiers and said that there is a whole set of methods for treating miasma?" Do you hide your relatives from yourself? ”

Fusu will go to Lingnan, both full of ambition and nervousness.

And Fusu is such a person, like an old hen, protecting the brother of your brothers and sisters. Why did Hu Hai make a fuss and follow Fusu? Albeit harsh, even somewhat pedantic, there is a sense of security.

When the catastrophe came, he was the first person to take the initiative to resist responsibility and shelter his younger siblings, but he had a slight Tang monk flavor, chattering, and being strict and dull.

"Do you know what the miasma is?" Yingyu asked straight in.

"The damp heat in Lingnan, the most terrible thing is the miasma, it should be a poisonous gas, as long as it is inhaled, the person who will die will be four or five out of ten."

"Under the scorching sun, the fog dissipates so that it will not be poisoned."

"Especially at night, the door must be sealed, otherwise the miasma will seep in and it will be very easy to be poisoned."

……

The brothers have different opinions, but due to the backwardness of cognition, they even blame all the unexplained causes of death in Lingnan on miasma.

In the land of Lingnan, the precipitation is abundant, the forest is dense, and the miasma is poisonous and insects like tigers.

In the second year of the unification of the world, the Great Qin sent troops to Lingnan, and lost 300,000 in the first battle, half of whom died of "miasma" or water and soil adaptation, due to the limited level of cognition, and in fact died of malaria, the source of which lies in the spread of mosquitoes.

The root cause is that the decay of animals and plants in the forest will produce poisonous gases, which cannot be dispersed in a relatively closed and humid space, resulting in the formation of bacteria and poisons, and this environment has become a breeding ground for mosquitoes.

However, this mosquito can transmit malaria virus.

The so-called miasma is deadly, especially in spring and summer, mosquitoes fly in swarms, chasing people and livestock like emitting evil gases, many of these mosquitoes carry malaria parasites, once bitten and infected, the death will be four or five out of ten.

The core of the so-called miasma treatment lies in the treatment of mosquitoes.

At the same time, ventilating the source of bacteria that are relatively closed and rotting in animals and plants can effectively reduce viruses and mosquitoes.

"Big brother, I have a little research on miasma.

Miasma is especially dangerous in dense forests.

If the garrison is camped, first find a ventilated place to camp. At the same time, the fire is burned, and realgar and atractylodes are added to remove miasma and mosquitoes, including poisonous snakes.

If you are walking through dense forests, you first need to wet your nose to filter poisonous gases, and secondly, to prevent mosquito bites.

If it is in the place of residence, the so-called dare not undress, dare not blow the wind, the doors and windows are closed, and the prevention is mosquitoes. ”

Yingyu continued, "I will prepare three more heavenly objects for the eldest brother, so that the eldest brother will not be afraid of the miasma, and at the same time, these three things will become the gods of Lingnan Qiantou." ”

"Tell me about it!" Fusu's eyes lit up.

"The first is alcohol."

Yingyu looked at everyone, "Presumably, everyone here already knows the power of alcohol, in addition to healing, it can also repel mosquitoes." If you are bitten, apply it promptly to disinfect it. ”

"Great goodness."

Fusu said happily, "The ninth brother is tired of going all out to produce alcohol, and I will leave for Lingnan after the spring planting ceremony, and all the alcohol produced in the past few days will be given to me, and alcohol is the first gift to Lingnan." ”

Fusu paced back and forth, and his joy was beyond words.

"It's a bit expensive to use alcohol directly. If you add geranium and peppermint, it is a mosquito repellent water, which is applied to bare skin, which smells good and repells mosquitoes. ”

Isn't this just toilet water? At its core, alcohol is all about it. Yingyu continued, "If you first cover your nose with a wet linen cloth and spray a little mosquito repellent on your body when you are walking through the dense forest, you will basically not be attacked by mosquitoes again!"

Regarding mosquito repellent water, I believe that as long as Brother Gao has alcohol, he will be able to produce a batch quickly! ”

"Thank you Ninth Brother for providing a secret recipe for mosquito repellent!"

Although Fusu mentioned to Yingyu that the mosquito repellent water has not been tried, and a number of heavenly objects have proved to be true, he is convinced of its effect and can't help but be overjoyed.

Then he looked at Gongzi Gao with a straight face, "Sixth brother, I will apply to my father tomorrow to build a mosquito coil workshop, and the sixth brother will definitely help the eldest brother produce more mosquito coils." “

Immediately paced in the hall with great ambition, "This is also the second that the eldest brother brought to the local area when he went to Lingnan, no, adding refined salt is the third gift." ”

"Huh. Don't bother with the eldest brother. ”

As soon as the words came out, Fusu was stunned, and it seemed that it was too different from what he imagined.

Gongzi Gao chose to ignore it, and said suddenly, "I will ask my father for instructions to add a workshop for the production of mosquito repellent water in my great medical department."

This thing is not only used in Lingnan, but even in Chuyan and Yan, there are many mosquitoes, and it can also be used!

Although a great doctor can help the world with a hanging pot, he can't have an empty stomach, right? This is the first pot of gold in my great medical department! ”

"Sixth brother, do you mean to provide mosquito repellent water, and I still have to pay?" Fusu looked incredulous.

"As the old saying goes, brothers, settle accounts!" Childe's high nostrils are facing the sky, with a natural demeanor.

"You?!"

Fusu suddenly had a black line on his face, and his fingers almost poked the sixth brother's expressionless wooden face, and then glanced at Yingyu with hatred.

"It's all your old nine who has a bad head!"

In the past, Fusu has always been unquestionable and unambiguous to his younger siblings, but since Lao Jiu collided, he found that the eyes of his younger siblings looking at him actually lacked the respect and worship they used to have.

Even, even the most well-behaved Yin Yan dared to resist him, this prestige is falling off a cliff!

Of course, Fusu was also as good as a stream, and whispered in his ear: "The first batch of strong wine, give it all to the eldest brother!" The ninth brother knows that Lingnan is bitter. Drinking a little strong alcohol before going out can also ward off miasma.

Besides, my brothers follow me, you can't drink the northwest wind, you can't catch anything, right?! ”

"Hahaha......" Yingyu couldn't help but laugh.

"Do you really think I'm a pedantic scholar?"

Fusu Jijue drank heavily and finally stripped off the posture of Gao Zaiyun, and his speech also had a human taste, and even a trace of ruffianism, "I have been in the army for more than ten years, how can I have so many hypocritical stinky problems." Eating meat and drinking wine together and talking vulgarly about women are excellent brothers! ”

"Poof......

The contrast of Fusu is too great, it is estimated that in order to show the best side of the eldest son, and at the same time deeply influenced by Zhou Li, for a long time, he has wrapped himself in a sleeve and lost too much joy of life.

"Absolutely."

Yingyu secretly rolled her eyes a few times, but her face was as warm as a spring breeze, and continued, "Regarding the first series of mosquito repellent, there are alcohol, strong wine and flower water.

The second sequence of mosquito repellent is the mosquito coil and sandalwood series! ”

……

"Ninth brother, tell me about the formula and principle?" The plain and indifferent Gongzi Gao knew that it was related to medicinal use when he heard it, and smiled at Yingyu.

"As I have just analyzed, the most terrible murderer in the miasma is mosquitoes.

Alcohol is too expensive after all, and mosquito coils are designed to repel mosquitoes. ”

"The sixth brother focuses on pharmacology, and knows herbs such as wormwood, realgar, duckweed, geranium, and atractylodes, supplemented by camphor wood powder, mixed into a paste to make thin strips, and dried.

In the dwelling, ignite it when needed to get rid of mosquitoes. ”

Gongzi Gao thought silently, his eyes getting brighter and brighter: "I didn't expect that the ninth brother actually knows Yin Li, so write the formula to me." ”

Yingyu took out a silk silk casually, thought a little, and wrote down the ratio of the so-called herbs, which is not oral, how can he know the ratio, it is all made up by feeling.

At the same time, he secretly said: "It seems that papermaking and movable type printing are going to be put on the agenda in advance."

Otherwise, not only for yourself, but even for the same text, if you use bamboo slips, it will not be popularized at all. ”

Gongzi took the craft silk silk of mosquito coil with a smile and carefully put it into his arms.

……

Jiang Lu couldn't hold his breath, got up and said, "Ninth brother, Pingsu is the closest to the two of us, what about the gift to the fourth brother?" ”

“（⊙o⊙）？”

"Good relationship? Nima, you haven't said a few words, have you?! ”

Yingyu secretly scolded herself, and then said, "This is the biggest opportunity for the fourth brother, that is, to give the eldest brother the third series of heavenly objects, hacksaw!" ”

"Hacksaw? What is it for? Fusu was stunned.

"The ninth brother is talking about building a batch of steel saws for the eldest brother?"

Jiang Lu was surprised, and then said with a dissatisfied face, "The saw is invented by the ancestors of Gongyi, and it is an artifact of logging, but it has been rarely used for hundreds of years, do you know why?" ”

"Sixth brother, wait a minute, what are you going to do with a batch of saws?" Fusu was puzzled.

"In the Qianshou living area in Lingnan, as long as the surrounding dense forest is ventilated, the miasma can be greatly reduced.

Cut dense forests through ventilation belts while burying dead animals. At the very least, the miasma and mosquitoes around the living area have been sharply reduced! ”

"Hacksaw through dense forest ventilation ducts? What a huge process this is? Fusu lost his voice.

"If there are enough saws, it's easy to solve!"

After thinking about it, Jiang Lu frowned and said, "The ninth brother knows that there is very little steel with high purity, and I am afraid that I will not be able to produce a saw that can be used repeatedly."

Besides, hacksaws aren't heavenly, are they?! ”

"Hehe, don't you know that the fourth brother still doesn't know that the Gongyi clan has obtained my secret recipe for iron smelting, and now he can train steel with high purity, and the hardness and toughness are good!"

Yingyu said leisurely, "In addition to the hacksaw, a batch of machetes and axes will also be built, as for how to control it, it depends on the eldest brother." ”

"Cutting down trees, working people and money, just for the dense forest to ventilate and repel mosquitoes?" Fusu's face was heavy, "It seems that the conscription of Lingnan Qiantou will be aggravated again, but some of the gains outweigh the losses?!" ”

"When the eldest brother went to Lingnan, he brought not only a hacksaw, but also a machete and axe, so that under the premise of protecting the ecology, he could plan to transform the forest, improve the living environment, and solve the problem of miasma.

The cut down trees were bought in six places in Shandong to create simple furniture such as tables, chairs and benches, so that Baiyue Qianshou had an extra income and a win-win situation. ”

"Great goodness, cure miasma, cut down trees and sell them in six places in Shandong? Killing two birds with one stone! Fusu immediately figured out the principle, and sighed with emotion, "The ninth brother has always been far-reaching, and the eldest brother is far inferior." ”

"Big brother, don't be presumptuous. Everyone has a specialization, sitting in Lingnan, the whole Great Qin is none other than the eldest brother! ”

Yingyu looked sincere, "It's just that my only worry is that the eldest brother is kind and kind, don't forget,"

"Confucianism and law are carried out simultaneously, rigidity and softness are combined, thunderbolt means, and the heart of the Bodhisattva."

Fusu repeated silently, holding up the wine, "Our brother drinks a jue." I will carve this into a wooden plaque and hang it in my home and temple! ”

"Finally, I'll give my eldest brother another gift to help him raise his taxes?"

"What's that, say it quickly?!" Fusu looked eager.

"The climate of the three counties in Lingnan is very suitable for growing sugarcane, and the planting of sugarcane is encouraged to be widely planted, which is purchased by the Central Plains to increase the income of the three counties.

Sugar cane is of great use to me, and it can be made into sweet sugar, whether it is sold to other countries or sold to the people of Qianshou, it is a considerable profit. ”

The so-called sweet sugar is brown sugar.

The diet at the end of the Warring States period was extremely monotonous. Apart from the bitter saltiness, there is little taste for the senses.

Sugarcane, on the other hand, is the raw material for the production of brown sugar, and the production is extremely high.

As long as the whole country solves the problem of food, the next step is the take-off of industry and commerce.

"The pattern and vision of the ninth brother, I admire the eldest brother! On behalf of the leaders of Lingnan, I thank you! After Fusu finished speaking, he got up and gave a long stroke.

"I can't afford it!" Yingyu hurriedly flashed sideways, and hurriedly helped Fusu up, sighing secretly in her heart, "As a traverser, a doctor of history, fortunately, I am familiar with the three great divine books of traversal." ”
