"Oh no, no, someone passed out."

"It's the kids who burn firewood......"

Fan Jingjing explained that everyone can only drink boiled water when they want to drink water, not raw water, so there is a group of children who are specifically responsible for boiling water.

"Let's hurry up and have a look." Fan Jingjing was a little panicked at this time, there was no one to rely on, only Fan Qi next to her was still her own person, so she called her.

At this time, it is better to have someone to rely on than no one At this time, her eyes suddenly fell on Niu Shijin.

She suddenly felt that if she was by his side, she would definitely be able to bring her greater courage.

It was the first time to bring such a large group of people, and she was also worried that someone would have a problem, but she didn't expect that someone would still have a problem under all precautions.

Approaching the place where the child passed out, Fan Jingjing noticed that there was a wisp of smoke drifting, and the faces of the people who were passing through the smoke did not look very good, and she thought of the poisonous trees mentioned in the previous university class, after picking up and burning, its smoke would cause poison to the human body.

"Stay away from those smoke ......," Fan Jingjing shouted anxiously.

Suddenly, Fan Qi pulled Fan Jingjing and said, "Master, calm down, everyone is watching, you must give everyone confidence." ”

After being reminded by Fan Qi, Fan Jingjing immediately realized that her current identity is different, she is the biggest leader on the scene, and her emotions will affect others.

She had to calm down, so she took a deep breath and looked carefully at their burning branches.

Her deep hope is not to clip the walnut, the oleander is too toxic.

As for the poisonous pomegranate, she didn't think it would grow in this place, it was a coastal plant.

"Is it it?"

Fan Jingjing did not allow everyone to burn the big tree trunk, thinking that the big tree trunk was an important building material, and there were so many children here, so she asked the children here to pick up branches or pull them down.

This is a wilderness, and there are a lot of fallen branches, so it is not difficult to pick them up.

What's more, it hasn't rained in the past few days, and the branches picked up can still be picked, but they are still dry or wet.

In this world, since Fan Jingjing crossed over to the Tang Dynasty, she has not seen a single rain.

After a rain in spring, the earth rejuvenates and sprouts, it is a common sense, Fan Jingjing believes that someone must have noticed the occurrence of this year's drought, and Fan Jingjing is not too afraid of the drought, she is afraid of this year's locust disaster.

She knew she couldn't stop the locust plague.

"Are those children dizzy and vomiting? Now move them out of the smoke zone, and then there should be a stream around there, scrub their nose and mouth with the stream, and fill them with plenty of water. Do not use raw water, some of their boiled water should be already cold, use those water. ”

Fan Jingjing immediately issued the next order.

The reason why people are flustered is that they don't know what they should do to have an effect, and once someone comes out to command, the chaos on the scene stops immediately.

Niu Shijin and Yu Chi Aya also arrived on horseback, perhaps because the situation was urgent, Niu Shijin got on Yu Chi Aya's horse, and it could be seen that Yu Chi Aya's face was red and fluttering.

"What's going on?" Niu Shijin asked.

Fan Jingjing tried not to look at Yu Chi Aya's face, and said to Niu Shijin who jumped off the horse: "There are a lot of black trees around here, so the child picked up a lot of black trees and burned them and boiled water. ”

Niu Shijin has some understanding of medicinal materials in the wild, Niu Jin Dawei, a soldier must be able to make full use of various materials in the wild, so Niu Shijin must know some common Chinese medicinal materials in the wild.

"Ebony?" Niu Shijin glanced at the scene and immediately confirmed what the black tree in Fan Jingjing's mouth was.

"It turned out to be a duck mortar, the root skin of the duck mortar is decoction and drinking, which can be laxative, and the white skin of the duck mortar root can be applied to the end of the white skin, which can remove the dampness and itching of the foot into sores. It is considered a medicinal herb. ”

Fan Jingjing knows that many ancient terms are actually different from modern times, and the simplest garbage was created after the Republic of China.

The black tree is called duck mortar, and the name is already very similar. Fan Jingjing also had no intention of exploring whether Niu Shijin was right or wrong.

This is not the point, the point is to save the child who has a problem, otherwise she will be in big trouble, they are tenant farmers, not serfs, not to mention that Fan Jingjing does not want a living life to die in front of her eyes, at least this is not a battlefield.

And if there is a large area of black tree forest nearby, and there is no need to plant it yourself, Fan Jingjing will make a lot of money.

In the industrial age, it may have lost much of its function, and it was not until people explored the search to replace oil that the oil quality of the black tree was re-refined and used as a living oil.

"You go back to eat first, and I have already dealt with the person who is in trouble."

In the era of agriculture when science and technology were not developed, it was a crop with high economic value.

It can be used as a natural insecticide; The seeds and skin of the fruit are covered with wax and can be extracted as candles for lighting or worship, or as soap for laundry.

In Fan Jingjing's impression, the soap of the Tang Dynasty had not yet been produced.

At least she doesn't have soap to bathe right now.

The leaves of the black tree can be used as a dye for dyeing cloth, and the boiled water of the leaves can also be used as an insecticide, or an ordinary pesticide, and this insecticide or pesticide is natural and has no chemical hazards.

At the same time, the seeds contain a lot of oil, which can be used as a source of lamp oil and can also be used for painters.

Even if the remaining seed residue is possessed, it can be used as fertilizer for plants.

The trunk of the tree is not easy to crack, which is preferred by sculptors, but it is not suitable for kitchen cutting boards, because toxins may be transmitted to food, and it is full of treasures, but it is also full of poison.

Fan Jingjing also knows that his wood can be used as furniture for daily life, made into pulp, and even made into a fun toy spinning top, and even convenient for growing shiitake mushrooms.

In addition to this, it can also be refined into substances such as solid alcohol, glycerin, wax paper, inks and fragrances.

In addition, the processing procedures are not too complicated, and it is a product of the pre-industrial era.

And judging from the branches in front of you, the proportion of the black tree forest here is quite high, and it is a mature black tree forest, so you can use it immediately.

Unfortunately, although the tree blooms and bears fruit in spring and summer, the fruit does not ripen until autumn and winter.

For Fan Jingjing, the most useful and economically valuable oils must not be harvested until autumn and winter.

With its toxicity, as long as it can avoid drought, it will definitely be able to avoid locust plague.

And Fan Jingjing, who can control humidity, estimates that even when a drought occurs, she can still squeeze water out of the air......
