He brought a lot of things, with electric mosquito coils in them.

After unscrewing the mosquito coil liquid, Ao Muyang poured some wind oil essence into it: "Double effect, mosquito removal is more domineering." ”

He took out a vial and showed it to Lu Zhizi, and said: "This is vitamin B1, you put it in a small watering can, and spray it in the room when you are idle, this mosquito repellent effect is very good, and the vitamin B1 aqueous solution is not harmful to the body after volatilization." ”

Finally, he took out some orange peels and put them on the balcony to dry, and said as he spread them out: "The sun is so strong, it will be dried at night, and you can burn two slices before you go to bed." ”

"Can this also repel mosquitoes?" Lu Zhizi was surprised, "Oh my God, I didn't know that I had read so many books in vain, and I really lived to learn." ”

Ao Muyang said: "Hehe, you don't know normal, this can't repel mosquitoes." ”

Lu Zhizi rolled his eyes and wanted to hit someone, Ao Muyang changed his words: "However, this can remove odors and cockroaches, you feel that mosquitoes are terrible now, and when the cockroach army arrives, you will know that mosquitoes are just pediatrics." ”

"Is that all there is to it?"

Ao Muyang shook his head and showed a bright shovel: "This is a physical mosquito repellent method, a chemical mosquito repellent method, and a biological mosquito repellent method." ”

After speaking, he carried the shovel and took the general and Ao Xiaoniu up the mountain.

More than an hour later, he returned with a bamboo basket containing some freshly excavated plants.

The condition of the elementary school is poor, the playground is dirt, and the yard of the teacher's dormitory is also muddy, so it is impossible to stay on a rainy day.

But dirt also has the advantage of supporting vegetation.

Putting down the basket, Ao Muyang sweated like rain under several windows in the house, digging soil pits on both sides of the windows and doorway.

After digging, he planted some shrubs with large green leaves.

Lu Zhizi studied for a while and said, "I know this, this is mint, and you still have mint grass on the mountain?"

Ao Muyang nodded: "This mountain is a treasure house, there is ...... everything"

Hearing this, Lu Zhizi said earnestly: "Really? I want a tank, and I want a guardian angel, well, Chanel's flagship store is also good, by the way, my computer is lost, can you find me a computer in the mountains? ”

Ao Muyang: "......"

Seeing that he had no love, Lu Zhizi laughed for a while.

Ao Muyang looked at her helplessly, and Lu Zhizi said: "Don't look at me with such eyes that care for mentally handicapped children, I follow your words." ”

"Do you also know that you are a mentally retarded child?" Ao Muyang teased, "Okay, let's get down to business, this is mint." It has a cool fragrance, not only used to repel mosquitoes, but also used for you as medicine, and then be bitten by mosquitoes and scratched, pick a mint leaf and squeeze the water to wipe it. ”

"And this, this is mosquito repellent grass, the scientific name is geranium geranium or what? It also has the effect of repelling mosquitoes, and it can also repel ants and bugs like bed bugs and cockroaches. ”

Hearing his words, Lu Zhizi showed a suddenly realized expression: "Oh, this is geranium geranium? I know, it can produce pyrethroid to expel mosquitoes, has the effect of dispelling wind and dampness, invigorating blood and dispersing stasis, and can stop bleeding and relieve pain for laryngitis, urticaria, and poisonous insect bites." ”

Ao Muyang looked at her in surprise, gave her a thumbs up and said, "It's amazing, do you still know this?"

Lu Zhizi shrugged and said, "Do you know that I have a doctorate and two master's degrees?"

Ao Xiaoniu said admiringly: "Teacher Lu is amazing, you are a genius!"

Lu Zhizi proudly held his head high and said: "If you bring me a bottle of Erguotou, I can be more powerful, and now what restricts my bragging ability is my thin skin!"

Ao Muyang quietly glanced at her chest, then glanced again, and finally said in surprise: "Are you?"

Lu Zhizi laughed again: "Of course it's nonsense, I just combined the effects of some Chinese herbs to say something, in fact, I don't know what I mean." ”

When they first met, Ao Muyang thought she was an elegant lady, but now he just wants to see an ophthalmology, why are his eyes so bad?

Ao Muyang said: "I don't know what specific effects mosquito repellent grass has and what specific ingredients it can produce, but it is really powerful in repelling mosquitoes and insects." ”

Lu Zhizi nodded and said: "Yes, it is geranium? Combining the ability of geranium plants and citronellal-containing plants, through photosynthesis, it can volatilize odor molecules such as citronellal, geraniol, linalool, etc., and insects are very sensitive to this odor molecule." ”

Ao Muyang said: "You don't drink the second pot of blowing, it's also delicious?"

Lu Zhizi hooked his hand at him: "Give me the phone." ”

Ao Muyang didn't know what she meant, and handed her the phone.

Lu Zhizi opened the browser of his mobile phone, then searched for geranium geranium, opened it and handed it to Ao Muyang.

Ao Muyang looked at the introduction of this plant in the encyclopedia, although there was no original words that Lu Zhizi said, but about its insect repellent ability, it was summed up as these.

Lu Zhizi said with a smile: "Let me tell you more, geranium geranium is native to southern Africa, and is famous for its extracts that have the effect of preparing flavors, perfumes and additives such as edible oils, soaps, and toothpastes. ”

Ao Muyang was surprised: "But how can we also have it on the mountain here?"

Lu Zhizi said: "You are saying that it is not quite correct to call geranium geranium, it is indeed a kind of geranium, but it belongs to the native species, the extract can not be used to make flavors and perfumes, but it has a good mosquito repellent effect, so the folk call it mosquito repellent grass." ”

Ao Muyang looked at her vigilantly and said, "Didn't fool me?"

Lu Zhizi laughed and said, "When did I fool you? Oh, you said just now? I didn't fool you just now, I wanted you to know who the mentally handicapped child is." ”

Ao Xiaoniu was confused and finally depressed: "I'm the mentally retarded child, right? What are you talking about?"

The general, who was hiding in the house to escape the heat, looked at the three people standing in the sun, and his dog face was very disdainful: It's so hot and still basking outside, I'm afraid I'm not running into a fool, right?

After finishing the work, Ao Muyang watered the mint and mosquito repellent grass, so that there would be a lot fewer mosquitoes in the house at night.

Lu Zhizi prepared a basin of water for him: "Come, wash your face and body, we will buy watermelon to eat later, I have a treat." ”

Ao Muyang wiped his face and said, "Do you have the money to entertain?"

Lu Zhizi said: "Of course, I didn't spend money to invite you to dinner last time, and my waist bag is very thick." ”

"How thick?"

"In exchange for a piece of RMB, it is estimated that there will be a bunch of dollars. Lu Zhizi said confidently.

Ao Muyang laughed and said, "Then you have to break the bill today." ”

There are watermelons sold in the fishing houses in the village, and the three of them went to Ao Mufeng's sea breeze fishing house.

Seeing Ao Muyang, Ao Mufeng said hello: "Brother Yang, your uncle is back, have you seen it?" I remember that Fugui said that your land is in their hands, do you want to come back?"

As soon as he heard this, Ao Muyang subconsciously asked: "My uncle is back? Isn't he working in Hongyang? Why did he come back suddenly?"
