Guangtong, which is known as China's four major woody oil plants together with Camellia oleifera, walnut and black tree, is commonly known as tung oil.

It can be said that the whole body of the tung oil is a treasure, which is why Ding Qi's eyes are fixed on the tree after recognizing this tree, and he can't take it off.

Tung oil leaves have the effect of clearing heat and reducing swelling, detoxifying and killing insects; The flower has the effect of clearing heat and detoxifying, and building muscles. The roots of the tree can kill roundworms, and the stomach is bloated by feeding; The bark contains tannins, which can be extracted to make barking agents. In addition to being used as a vomiting agent, the most important tung oil squeezed from tung fruit has the characteristics of fast drying, shiny, alkali resistance, waterproof, anti-corrosion, anti-rust, non-conductive, etc., and is an important industrial oil. The manufacture of paints and coatings has particularly good waterproof and anti-corrosion properties and high economic value.

Moreover, the peel of tung oil contains 3%~5% potassium, which can extract tung alkali and potassium carbonate. The peel is burned with ash, soaked in water to dissolve the potassium, filtered and then evaporated, and the soil alkali can be obtained after drying. Soil alkali can be used in potash fertilizers, glass, cosmetics, soft soaps, spices, dehydrating agents, sweet tanning agents, silk and wool detergents and medicines. In the present primitive social period, at the existing level of productivity of the Ding tribe, the needs of wool washing, animal skin tanning, and soap making can be met.

The residues of oil extraction are processed to make livestock feed, olefin oilseeds, compound fertilizers, and pollution-free long-term pesticides. Tung cake contains 77% organic matter and is a highly efficient organic fertilizer. Its wood is soft and can be used as light furniture.

The role of the tung oil is really too much, especially the current problem of leakage of the hull made by the tribe, which will be solved, and then Ding Qi can consider rowing along the big lake to enjoy the scenery.

When it comes to lakes, there is always a suspicion of the nameless lake. In view of the importance of the lake in front of the tribe, and in order to remind himself of his identity at all times, and the lake is located in the south of Ning City, the lake was named South Lake by Ding Qi!

A very sacred, monumental name.

Traveling with beauty on the South Lake? It's not too pretty!

At this time, I don't know what happened to the girl who was deer, not to mention, I really miss her a little! Ding Qi had some thoughts in his heart.

Today, the teaching and training work in the tribe is all on the group she leads, and batch after batch of newcomers join the tribe and have to study the language. And the rapid development of the tribe requires more skilled craftsmen, and these craftsmen come from the training class of deer.

Especially the doctors and witches, they have been having a headache with the knowledge, technology, and cultural inheritance of their original tribe, but now fortunately, with the writing invented by the Aragami, these problems are not a problem, which has stimulated their interest in learning, researching, and contributing to the tribe. Moreover, Ding Qi promised them to provide them with a better recording tool than a slate, which made them more diligent, as if they had been beaten with blood.

What Ding Qi didn't expect was that the group of people in the tribe who were most interested in learning were the Witch Doctor and the Elders, and they also had the highest mastery of Chinese characters, having reached the level of the fourth grade of primary school, and they were all about to catch up with the first group of people in the tribe to learn Chinese characters, such as Xue and Dan. This has something to do with the fact that they are the upper echelons of the original tribe and are smart in their own right.

For this matter, Ding Qi thinks it is a good thing. If the development of a tribe's education cannot keep up with the speed of the development of the tribe, or the speed of social development, it will be a failed education and will be eliminated by history.

As I just said, in addition to the teaching of Chinese characters, Lu also has an important job, which is the teaching of core knowledge and skills within the tribe. For example, a series of jobs such as mineral processing, smelting, alloying, casting and blacksmithing are not just a few to come over to learn, but to be carefully screened. Strict selection was made in terms of origin, mastery of kanji, interests, abilities, age, and even political background (views and loyalty to Aragami and the tribe), and after a series of selections, there were less than 50 of them that could meet the requirements.

Among them, the most important thing is their origin and political background, or their attitude

。 Attitude determines everything, and attitude determines a person's height. Such a well-tempered sentence is definitely a wise saying, which can see most of the problems clearly.

These people are selected and they are subjected to rigorous training and practice. The deer group has only mastered the basic knowledge and skills, and the more advanced content has to find the corresponding craftsmen to teach, go to the site for practice, return to the furnace to learn, and finally go to various important positions according to everyone's interests.

They are the future of the tribe!

Looking at the tung oil in front of him, looking at the green fruits on the tung oil, Ding Qi couldn't calm down for a long time. Familiar and unfamiliar, I feel that the leaves are larger than those planted in the countryside, and they are almost the size of a basketball.

Under the tung tree, the weeds do not grow tall, there are rotten branches and leaves, and occasionally some tung oil seeds can be seen. Ding Qi looked left and right, the area of this piece of tung oil is about more than fifty acres, there are no small trees growing under the tree, only those large tung trees that have fallen in the middle of the gap will have five or six small tung trees growing. However, under the natural law of natural selection, in the end, only one tung oil tree can grow into a big tree.

In this case, underneath the tree, there are just some weeds that don't reach the knees.

Tinckey crouched down and rummaged through the weeds for a while, finding five or six wrinkled fruits that were larger than eggs. The peel is shaped like a turtle's back, tightly constricted, and somewhat similar to a peeled walnut, some are black, some are yellow, and apparently they fall at different times. There was a fruit with signs of rodent gnawing on the outside, and one fruit was half rotten, and the other half was also nearly rotten, and the seeds inside had disappeared.

Holding an intact fruit, rubbing his fingers vigorously, the thick husk is pinched open, revealing the wide ovoid seeds inside, which is the tung oil seeds that can squeeze out oil, and the oil yield of the kernels inside will be higher.

Seeing that the seeds are still intact, it means that there are still many undamaged fruits in this tung oil forest, and you can collect more and go back to extract oil.

Do what you think, arrange for Ling to brag about the horn, and gather others to come over.

"Woo~"

Ling quickly climbed a leafy tung tree, stood on a branch, exposed his head, and blew the horn.

By the time everyone else had come, Ding Qi and the five of them had already picked up a lot of tung oil fruits, and they were all piled on the animal skins on the side. At this time, the rain had not yet fallen, so Ding Qi asked people to pick a lot of tung oil leaves and go to the position of the horses halfway up the mountain to build a rain shelter. I will definitely not set off again today, and the horses will not be able to come up again, so I want to build a shed here to protect from the rain and rest.

Everyone has a clear division of labor, two people set up a shed, two people hunt, and the rest of the people follow Ding Qi to pick up tung fruit together.

When Yun saw this fruit, he was also excited in his heart, and his heart said that he had found the treasure again, otherwise the leader would not be so excited.

"Chief, this fruit is a good treasure, can it be used in medicine? It's delicious or not, why don't I try the medicinal properties first? I am deeply inspired by the story you told us about Shennong tasting herbs, and my generation should take Shennong as an example and contribute to mankind by tasting herbs. ”

After speaking, without waiting for Ding Qi's reply, he rubbed a yellowed fruit in his hand, ready to throw it into his mouth to learn from Shennong to taste the herbs.

"Smack!"

A hand reached over and knocked the fruit off the cloud's hand.

"If you want to kill yourself, then I won't stop you, I'll miss you today next year!"

After Ding Qi saw the cloud's movements, he hurriedly shot to knock the fruit off.

"These trees are called tung oil, and their fruits are poisonous, especially fresh fruits, which are even more toxic. Vomiting and abdominal pain can range from life-threatening to the worst. Moreover, the bark and leaves of the tung tree are also poisonous, so do not swallow them. However, its leaves are also medicinal, with the effect of clearing heat and reducing swelling, detoxifying and killing insects. You can try these slowly, and remember not to swallow them again. ”

Ding Qi explained these tung oil to the cloud as he spoke

Medicinal properties, as a person who has been in contact with the tung oil on the side of the road since childhood, I still have a good understanding of the characteristics of tung oil, at least there will be no poisoning caused by eating tung oil fruit by mistake.

"Boom! Crack! ”

A flash of lightning suddenly sounded in the sky overhead, and soon a cool breeze blew, and the raindrops the size of beans fell on the wide tung oil leaves, making a "poof" sound, which had not yet fallen on the people under the tree.

Hearing the thunder, everyone's bodies began to tremble, which was the instinctive fear of thunder and lightning contained in the body for millions of years. Ding Qi, who understood everyone, beckoned everyone to hurry down the mountain and take shelter from the rain under the rain shelter halfway up the mountain. Others had already lit a bonfire for everyone to eat on the barbecue.

Although it is the height of summer, there is still some coolness on the mountain, and there are very few mosquitoes in the corresponding area, and you have to cover an animal skin on your body when you sleep at night.

When night fell, everyone gathered around the bonfire, and under the background of the sound of raindrops beating on the tung leaf shed, Ding Qi told everyone the story of Shennong tasting a hundred herbs.

"Last time, I said that Shennong got a baby bird named Flower Bird. This stamen bird is a miraculous thing, its body is transparent, you can see everything in its body, including its heart, liver, lungs, blood vessels, including everything it eats moving in its body. ”

Ding Qi picked up his military water cup from the fire, took a sip of strong dandelion tea, glanced at Yun who was listening attentively to the story like a child, smiled slightly and continued:

"In order to know the medicinal properties of herbs and their effects on the body, Shennong boiled a medicine, fed the stamen bird to eat, and watched the walking route of the herb in the bird's belly, remembered the changes in the body, and then took a mouthful of the medicine himself, and felt the medicinal properties ...... himself."

The people around him who could hear it would applaud and cheer when Ding Qi talked about the highlights, and they would also pick up their teacups, take a sip of tea and continue to listen to Ding Qi's example, just like a group of people who listened to people talk and drink tea in the teahouse.

In the middle of the night, when the clouds and rain subsided, the sky showed the playful eyes of the stars blinking, and people who were tired of the day quickly fell asleep with endless aftertaste. Ding Qi was smiling sweetly at this time, swinging his oars with both hands in his dreams, rowing a brisk boat, carrying the medical witch deer on the South Lake.

The deer wore braids, a white shirt, a pleated plaid skirt, and his hands on his cheeks, listening to Ding Qi sing the song "Let's Swing the Sculls". In the beautiful melody, a large white sturgeon jumped out of the water, splashing waves more than one meter high, forming a colorful rainbow bridge under the sunlight, and sprinkling a bell-like laughter.

Suddenly, Ding Qi in the dream suddenly found that the water around him was boiling like boiling water, as if thousands of fish were jumping out of the water below, and even the bottom of the boat felt a shock, which made people feel a sense of shock.

"Boom~"

There was a thunderous sound in the valley, the ground shook, and the beasts seemed to roar.

Ding Qi woke up suddenly, and heard Xiao Erhei and the others stomping on the ground a little irritably, trying to break free from the reins. The cutie next to her, with hair standing on her neck, seems to have a great fear of this voice. Not to mention the group of people who were already on their knees at this moment, trembling, praying for God's blessing.

Ding Qi saw the situation around him the moment he opened his eyes, and combined with the movement of himself and his feet, Ding Qi quickly judged that there was no earthquake, but there was also a natural disaster that made people feel chilled.

Flash floods!

Cold sweat, drop by drop, slid down the forehead. Should we be rejoicing? Or is it that he was prophetic, or is there an invisible force that pushes him to make the choice to summon his people?

Ding Qi, who had just stood up, sat down again, snorting and panting, and the adrenaline secretion was sharply secreted, causing his body to be a little unbearable because he couldn't vent, and he felt that his little heart was about to jump out.
