After the Dragon Boat Festival, the weather became hotter day by day, and the students of the county school began to reach the most difficult time of the year. Compared with the coolness of the countryside, the rooms in the county town were like steamers, which were sultry and hot, and there were many mosquitoes, which was unbearable.

At night, the magpie and chrysanthemum lit the rope mugwort. Soon, a stream of green smoke began to spread to every corner of the room. The rope mugwort was a mosquito repellent object from the Song Dynasty. It was weaved with wormwood and mugwort and then lit it. The ignited green smoke will drive away mosquitoes, and the effect is pretty good.

This is a mosquito repellent used by ordinary people. It costs two cents per piece, and each piece can be kept overnight. But the trouble is that it cannot be ignited all the time, and it has to be rushed to death every once in a while.

Fugui family uses a fumigation furnace to ignite spices mixed with mugwort powder, which is both fragrant and repels mosquitoes. In addition to incense, Fugui family also installs brocade windows and gauze tents on the bed. Mosquito nets have become popular in the Song Dynasty. As long as the family is not too poor, almost every family has several mosquito nets.

"Little official, there are no mosquitoes over us. I'll repel mosquitoes for you!" The magpie leaned in and said with a smile.

Li Yanqing was sitting on the bed and studying "Mao Shiyi" hard. A ten-axle tent was placed around him to cover the entire bed, like a tent, with bright lights in the tent and mosquitoes crawling on it.

"Okay! I feel upset when I hear them calling."

Although mosquitoes can no longer bite people, the buzzing sound in the room also really affects learning.

The magpies ran in, holding a mugwort rope with green smoke in their hands and waving around the mosquito net. Soon the room was filled with mugwort as the smell, and the mosquitoes gradually disappeared.

"Little official, it seems that there are no mosquitoes."

"Well! There is nothing else except a very large mosquito flying around."

The magpie gave him a blank look and said, "I have no conscience. I kindly help you repel mosquitoes, and I also said that they are big mosquitoes and ignore you!"

The magpie turned around and was about to leave angrily. Li Yanqing hurriedly said to her: "I'm a little hungry, see if there is anything to eat in the kitchen?"

"knew!"

Soon, Magpie brought a plate of buns, which were made by Ju Sao himself. The meat buns were very delicious, which made Li Yanqing praise him.

Li Yanqing asked while eating, "How is Brother Yue?"

"He is like you, but he is more attentive than you to read books. He neither asks people to drive away mosquitoes nor calls him hungry, nor does he laugh at others as big mosquitoes."

The magpie is still resenting the joke that the little official just made.

At this time, Wang Gui's roar came faintly from the distance, "Beat you damn mosquitoes to death, bite me to death!"

The magpie covered her mouth and laughed out loud, whispering to Li Yanqing: "Little official, Gui'er is practicing weightlifting in the yard! So is Brother Tang, too, he was bitten by mosquitoes so much."

Since they decided to take the martial arts exam, Wang Gui and Tang Huai gave up their studies completely. They spent most of their time practicing martial arts every day, and even at night they were very diligent. One was practicing weightlifting hard in the yard, and the other was walking back and forth on a foot-high wooden stake with an iron sand bag tied on his legs.

Li Yanqing smiled and said, "There is no way. No matter how hard the path you choose, you have to continue. But... they are stupid and can practice in the house! Why do you have to feed mosquitoes in the yard?"

"He said himself that he would only know how hard he was when he saw how many mosquito bags he had on his body."

Li Yanqing curled his lips. When did Wang Gui learn to do a face-saving project?

At this moment, the mosquitoes dissipated and the mosquitoes covered the mosquito net again. The magpie stomped her feet in anger and turned around and ran towards the kitchen. She had just cut off the mosquito rope, and now she had to find the flint to reignite it.

Li Yanqing looked at the densely packed black dots on the tent, but he was thinking about how to make mosquito coils. It was actually very simple. Use toner and realgar powder to mix it with dry inulin, and then dry it.

Although it is easy to make mosquito coils, he doesn’t have time to consider these trivial matters. He will be in the imperial examination in five months. He carefully interpreted the interpretation, which will take at least half a year, and he will also spend time practicing calligraphy and writing strategies. The huge academic pressure makes him wish he would not sleep at night.

Li Yanqing sighed softly, if the grain store had not been dissolved, this would be a new way for the grain store.

......

The next afternoon, Li Yanqing and the other two came back from the county school. The weather was so hot that it seemed as if there was a fire on the ground. They were sweating all over when they moved. The four of them were like scorched wheat leaves, with their heads hanging down and listless, and no one wanted to say a word.

Li Yanqing turned over and got off the horse. As soon as he walked into the gate, he saw the magpies trot all the way up to him. Li Yanqing felt a wave of heat coming towards him. He smiled bitterly and said, "My aunt, don't run away. Once you run, the whole heat will come up."

The magpie smiled and slapped Li Yanqing's ponytail and whispered: "Little official, my uncle is here."

The magpie's uncle is Li Dongdong. Li Yanqing hasn't seen him for a year or two. He happened to think of him last night, so he came. It's such a coincidence.

"Where are others?" Li Yanqing asked hurriedly.

"Drinking ice licorice soup in the study!"

I heard that there was ice and snow licorice soup at home. Wang Gui and Tang Huai didn't care about sweating all over and rushed to the kitchen, "Sister Ju, where is the ice and snow licorice soup? Are there any ice and snow cold meatballs?"

"Brother, it's been a long time since we met."

Li Dongdong walked out of the inner courtyard quickly. He wore a straight piece of light silk and a sweat towel on his head. His appearance was no different from a few years ago.

Li Yanqing asked with a smile: "Where did Brother Dong come from?"

"Of course I'll come from the capital! Let's take a look at my little brother."

Li Yanqing wiped the sweat from his forehead, pulled his inner sack soaked in sweat, and said to Li Dongdong: "It's too hot here. Let's sit in the room, magpies, pour two bowls of ice-snow licorice soup. This is really hot!"

"Yes! The capital is also hot. In comparison, Tangyin County is a little better. The whole capital is like a big steamer. If you stay for a few more days, people will be steamed."

The two walked into Li Yanqing's study and sat down. The magpies smiled and brought them two bowls of ice and licorice soup. Li Yanqing picked up the bowl and drank it all. A cold air came out from the soles of her feet, and her whole body suddenly became cool.

"Little official, let's have another bowl! We bought a jar."

"Okay! Another bowl."

"Don't you want another bowl, too?"

Li Dongdong waved his hand quickly, "I've had enough, just give it to your little official."

The magpie was about to go out. Li Dongdong looked at her back and shook her head and sighed: "In the past, she was beaten and scolded by her father at home. She was frightened and scared all day long. She had never seen her laugh before. After following the little official, she became so happy. It can be seen that the little official treats her very well, which is also her blessing!"

Li Yanqing smiled and said nothing. Li Dongdong pondered for a moment and said, "Your father and I have disbanded the grain store. My brother should know about this!"

Li Yanqing nodded, "Actually, I don't think you should have disbanded the grain store. It took a long time to open up the situation and just shut it down. Five years of hard work were wasted."

"There is no way to do this. Without the patriarch, we will lose the backbone. The food store will lose sooner or later. Instead of losing all the money they earn, it is better to stop in time. Your father and I think this is the best decision."

After pausing, Li Dongdong asked again: "Where has your father been? There was no news about him after the breakup in Anyang."

"He is now going to CD and he wrote to me that he would go to Bashu for a month or two, and then take a boat to Jiangnan."

"It's so enviable!"

Li Dongdong sighed long, "Your father is single and relaxed. Unlike me, he has old age and young age. He can't rest for a day and has to continue to support his family."

"What business is going to do in the future?"

"My family is determined to open a tavern or inn. The cost is enough, but I am always a little unwilling to give up. I want to ask my brother if he can help me show me a way to make money."

Li Dongdong admired Li Yanqing very much. The reason why he can have a net worth of thousands of yuan today is entirely due to Li Yanqing's guidance back then. So when he fell into a lost path again, he thought about asking Li Yanqing for advice again.

Li Yanqing smiled and said, "Actually, it's good to open a tavern. If you choose the right market entrance, you can make sure you make a profit. There is also a small deal now. I think you can do it and you should be able to make a small fortune."

"Please say it with a good friend!"

"It's the mosquito that is upsetting right now. We just need to use our brains a little and there is money to make money in it."

Li Dongdong was excited and hurriedly said, "Is there any way?"

"Actually, it's very simple. Rich people use incense, poor people use moxa ropes. What about ordinary people? Combining incense and moxa ropes is a mosquito repellent used by ordinary people?"

Li Yanqing thought of mosquito coils last night, but he didn't have time to do these business. Just as Li Dongdong came, he could give this idea to Li Dongdong. Maybe they can continue to cooperate in the future.

Li Dongdong lowered his head and pondered for a long time, shook his head and said, "I really can't figure it out, I'll teach me!"

Li Yanqing smiled and said, "We usually burn incense, and the incense is very cheap. You can buy two pieces for a penny. Why can't we mix mugwort powder and incense together, and then insert it on the incense burner and burn it overnight? Wouldn't we go to sleep peacefully?"

Li Yanqing discovered the inconvenience of moxa rope. One is that the smoke smell is too strong and it stimulates people's eyes. The second is that it is burned too fast. Every time it repels mosquitoes, it must be extinguished. Then, after a while, it will be ignited and repelled. This will cause three or four times a night and it will not sleep well. The mosquito coils solve the trouble of keeping up the night.

Li Dongdong's eyes lit up, "Yes! Why didn't anyone think of such a simple method? We can make the incense longer and it's no problem to light it overnight."

Li Yanqing smiled and said, "The fragrance does not need to be made too long. It can be broken easily. It can be made into a swirl shape, circle around it, calculate the time, just order it overnight. In addition, in addition to using mugwort powder, you can also grind it with dried chrysanthemum into powder, mix it into powder and mix it in toner and realgar powder. After ignition, the mosquito repellent effect is also very good, and it is also very fragrant, much better than mugwort rope."

"Can chrysanthemums repel mosquitoes?"

"Of course, the effect is much better than mugwort. If you don't believe it, you'll try it tonight."

Li Dongdong was so excited that he rubbed his hands. He happened to know a few craftsmen who made incense and could ask them to make a few mosquito repellent coils to try. If they sell well, they can earn at least a few hundred chunks in a summer.

Li Yanqing smiled and reminded him, "The signboard is very important. I think it's called Li Ji brand mosquito coil. I will teach you how to make mosquito anti-mosquito dew in the future. It's a must-have for wealthy people in summer. Maybe the emperor will not be able to leave it in the future, and our reputation will come out at that time."

Li Yanqing's few words seemed to open a window for Li Dongdong to get rich, making his horizons wide open. In the distance, there seemed to be shining mountains of gold and silver.

He was not willing to wait before talking, and took Li Yanqing's hand and begged: "My little God of Wealth, please tell me how to do mosquito anti-dew now, don't wait for the future."

Of course, Li Yanqing would not tell Li Dongdong how to make money for no reason. He actually wanted to find something for his father. Although the grain business could not be opened, they could do other businesses. They have been working together for five years and can continue to do it.

Since Li Dongdong has already set out, Li Yanqing smiled and said, "It is better to make money by one person than everyone else. How can we join forces again?"

Li Yanqing's suggestion reached Li Dongdong's heart. Although he could do business alone, the couple was illiterate and were always deceived. If Li Daqi could continue to do business with him, then with his mind and Li Daqi's help, I believe they would succeed.

Li Dongdong smiled and said, "Actually, I came to you to have this idea. Although we can't do grain business, we can do other business."

Li Yanqing smiled and said, "Mosquito repellent is just my initial idea. You can go back and try it first. If it succeeds, we will talk about cooperation. There will be many opportunities in the future if it takes a long time."

"Can you tell me the recipe for anti-mosquito dew? I want to make two things together, and the possibility of success is greater."

Li Yanqing thought a lot. He could also make soap, perfume, shampoo, shower gel, etc. In the future, of course, Ruth took it step by step.

Mosquito repellent products were just his thought last night. Whether the market could accept them is still the same thing. Li Dongdong can give it a try first. If the market can accept them, they can continue to cooperate and expand their business step by step.

Li Yanqing immediately told Li Dongdong about the recipe of mosquito anti-mosquito liquid. In fact, it is very simple. After pressing and soaking with wild chrysanthemums and honeysuckle, apply water to the skin so that the mosquitoes will not bite. This is a very effective folk remedy.

Li Dongdong was as if he had a treasure. He didn't even have dinner, so he rushed back to the capital overnight and started looking for craftsmen to make Li Ji brand mosquito coils and mosquito anti-dew. In fact, Li Yanqing also knew that mosquito coils were simple, but they were not easy to make. The key was to ignite them for more than three hours to ensure that they could not get up at night.

But it’s better to ask Li Dongdong to try it. If you try it a few more times, you will succeed in the end.

The other two agreed that if these two mosquito repellent products can be successful, they will join hands to open a new business to bring more trendy products to the market.
