The servant of Ying, the god of the Red Chamber, only loves farming

Baoyu's head was filled with the sounds of the Huahuas crying, and the Huahuas were all complaining to him that the insects bit them so painfully.

[These are aphids.The strong fragrance of roses often attracts these insects.Aphids love to eat flowers and leaves, and the flowers and plants that have been eaten by aphids are not as good as those that have not been infested by aphids. 】

[And these little bugs can infect other flowers.But children are not afraid, Xiaohua retrieved the following recipes to help get rid of pests. 】

Baoyu had a few more methods in front of him, some used the juice of onion, ginger and garlic to repel insects, and some used pepper juice.

"Pepper juice?" Baoyu was puzzled when he saw this, "Isn't the pepper poisonous? I heard from Mingyan that there was a person who didn't know the pepper and died after eating it by mistake." Baoyu looked around in fear. He whispered, "It is said that the appearance of death is terrible."

Baoyu said it was as if he had seen it with his own eyes.

[Children, pepper is a very good condiment.Such as boiled beef, mapo tofu, spicy strips, etc. are inseparable from pepper!The system has detected that the current acceptance of pepper is not high. If children successfully promote pepper, they will definitely gain a lot. 】

Is what Xiaohua said true?Baoyu had doubts in his heart, can peppers... be eaten?

[Automatically search for gourmet atlas related to pepper...ready to play. 】

The system is not allowed to be questioned!

Baoyu stared at the fiery red colors on the screen without blinking, and swallowed involuntarily.

Baoyu clapped his hands after Xiaohua finished displaying the atlas and said, "Tomorrow I will ask my grandmother to give me a pot of hot peppers! Xiaohua, you will teach me how to eat when the time comes!"

Xiaohua looked at Baoyu who was so careful, and always felt strange in her heart.Is it the wrong way?

Why do I always feel that children are trained to be snacks by it.

[Kids should solve the aphid problem first~]

Baoyu patted his little head, he almost forgot about the rose flower.

According to Xiaohua's instructions, Baoyu first separated the flowers with bugs from other flowers to prevent the bugs from infecting healthy flowers.Then Baoyu washed the flowers and leaves with clean water to wash away the bugs, and Baoyu carefully trimmed off some stems and leaves that were bitten by the bugs.In the end, Baoyu mixed these insect repellent waters one by one according to the prescription given by Xiaohua, and experimented on plants with pests.

A few days passed, and there were indeed fewer bugs than at the beginning; but some tenacious bugs were still alive under his "poisonous tricks".

Baoyu supported her little head and asked, "Xiaohua, I did as you said, but the little bug is still there."

【Children, I'm sorry, because of the limited conditions, we can't make chemical pesticides, so we can only recommend these relatively simple and easy-to-obtain ones to children.However, Xiaohua searched the environment just now and found that there is a bitter bark vine that may help children solve this problem. 】

"Bitter bark vine?" Baoyu insisted on asking without understanding, and the system Xiaohua immediately popularized the bitter bark vine to Baoyu.

It turns out that the bark of the rhizome of bitter bark vine can kill insects!

Xiao Hua told Baoyu that the bitter bark vine contained in bitter bark vine is a highly effective insecticidal substance, but this bitter bark vine is difficult to extract. If the extraction is successful, just a little bit of water can protect the flowers from insects. Infested by insects.

After hearing this, Baoyu urged Xiaohua to tell him the extraction method quickly.

[Extraction of paretin, you can use the heat reflux extraction method.Xiaohua can provide you with a schematic diagram of the thermal reflow device, but glass equipment is not popular; but children can try to use copper instead~]

Baoyu drew the schematic diagram and ran to find Jiamu; Jiamu couldn't see what it was, but thought it was a paper pattern for a new toy that Baoyu liked to play with, so she asked the steward of the house to find a craftsman to print it according to the drawing. out.

The device that Baoyu wanted was more complicated, and the blacksmith had never seen such a strange thing, not to mention that it needed to be cast in copper.

Baoyu waited for nearly half a month for the device that Xiaohua said. The skin of the rhizome of Kupi vine was peeled off, dried and ground into powder, and then wrapped in rice paper and placed in a cylindrical copper tube in the middle; Some sorghum liquor was added to the upper pipe; a fire sat under the copper bottle at the bottom.

Baoyu couldn't see the changes in the whole device, and was very curious about what it would look like inside.

"The system turns on the structural scanning mode, and children can see the changes in the copper bottle through the system."

Baoyu opened his big black eyes, and let out a sound of surprise from his mouth; water gradually seeped out of the bottom round bottle.

Xiao Baoyu sat on the small bench and stared at the copper vase without blinking, followed by Zhuzhu who looked left and right but didn't understand what was so special about the copper bump.

"Kids have finished extracting the bitter bark vines, please store them carefully; the system will list out the formulas for you to use as a reference for children to experiment."

Baoyu found a porcelain bottle and filled it with bitter bark vines, happily sprinkled the insect repellent liquid on the flowers and plants in the flower hall according to Xiaohua's description.

Within two days, those struggling little bugs disappeared completely.

"Xiaohua, you are amazing!" Baoyu clicked on the system's evaluation page and filled five little stars without hesitation.

System Xiaohua was a little blissful.

"The device provided by Xiaohua can not only extract picroderm, but also extract essential oils. Adding different essential oils to grease soaps can have different effects. Children, do you want to try it?"

In a few days, the flowers in the flower hall will bloom, and Baoyu rubbed her little hands, eager to try.

Baoyu extracted another bottle of bitter bark vine and went to find Jia Zheng.

"Father, father!" Since Xiao Naibao plucked up the courage to tell Jia Zheng what she thought that day, she was much less afraid of Jia Zheng.

Just as Jia Zheng was in the study, Baoyu opened the door and ran over; his face was full of smiles.

Baoyu was very studious these days, and Jia Zheng saw that his attitude towards Baoyu softened a little.Baoyu took out the porcelain bottle in his hand and showed it to Jia Zheng, and said excitedly and incoherently: "This is the bitter bark vine that Baoyu has newly extracted. Baoyu wants to give a bottle to the prince."

Jia Zheng looked left and right with the porcelain bottle in his hand, lifted the lid and sniffed a strange but inexplicable smell.

Jia Zheng put the lid back on and asked, "What do you mean by this bitter vine?"

Baoyu held the porcelain vase like a baby and replied: "This is called kupitengsu, which is used to repel insects in flowers and plants. Some flowers and plants in the prince's house are sick. Just one or two drops of this thing in the water can make the flowers and plants grow healthily." .”

Jia Zheng scolded in a low voice, "Nonsense! Reading is important, how can you waste time on these rootless things." Jia Zheng didn't believe that the little bottle in Baoyu's hand was so powerful. This incident made Jia Zheng's heart tense.

It seems that Baoyu's schoolwork should be a little heavier, so that the child will not be too lazy to play with things and lose his mind.

Baoyu said aggrievedly: "I have completed the homework assigned by my father seriously. My father also promised that my grandmother would not restrain Baoyu from planting flowers. And Baoyu promised my father that the prince will like this!"
