Who knows! As soon as I returned to the mountains to farm, I encountered a natural disaster.

Pigs like to poop under the wall farthest from the trough, so Mu Xi dug a long trough there to make the inside of the pig pen cleaner and easier to clean.

Rice straw was laid on the floor of the pig pen, and as soon as the little wild boar was put in, he lay down and fell asleep.

Recalling his previous plan to shave wool, Zhao Yeqing washed his hands and went back to the tool room, took out the electric clipper and plugged it in to charge.

We can't shave today, it's almost dark, and there will still be a bit of coolness after nightfall. Shaved sheep are prone to getting sick, so they can't be shaved until almost noon tomorrow.

Shaving work is best done by two people working together for the most efficiency. Although the sheep at home are more obedient, they still sometimes have sudden convulsions, and it still hurts when they are kicked.

The white wool was pushed down with the sizzling sound of the electric clipper, and three full sacks of wool were obtained.

After the sheep were shaved, everyone in the sheepfold was smooth except for one, which was kept for slaughter.

Zhao Yeqing was processing the newly shaved wool at home, and Mu Xi planned to visit the orchard.

There were already a lot of fruits bearing fruit last time I went there, so I might be able to pick ripe ones this time.

With the experience of being bitten by a leech last time, Mu Xi was extra cautious this time and was fully armed. He wore a coat with a hood and tightened the elastic band on the hood, leaving only a pair of eyes exposed.

The leaves of the citrus trees are glossy and slippery, reflecting the golden sunlight. The whole orchard looks shiny from a distance.

Mu Xi walked around the orchard and found no ripe and yellow fruits.

The largest fruit is already five or six centimeters in diameter. It should be ripe, but the skin is still green.

Could this be green peel tangerine?

He remembered that when he was a child, fruit farmers near Meishan would also grow green-skinned tangerines. The skin was very thin, only about one millimeter thick.

Mu Xi picked one and when he tore open the peel, he discovered that the pulp inside was already very long and full, and the color was lighter than that of normal citrus.

Tear off a piece and stuff it into your mouth. It's seven parts sweet and three parts sour.

Mu Xi loves sweetness, but cannot tolerate sourness. As soon as the tangerine enters his mouth, he squints his eyes due to the sourness.

But this should be what Zhao Yeqing likes.

He raised his hand and pinched each fruit of suitable size. If it was too hard, he didn't want it. If it was slightly soft, he picked it and put it in a basket to take back.

Only about a dozen fruits are ripe, and most of them will take another month or so.

It was already evening and getting dark when Mu Xi brought the fruit home.

Zhao Yeqing is watering the crops in the field. The current temperature is more suitable for evening watering. The sun at noon is still a bit strong and will not cause the plants to dry out. Watering in the evening is the gentlest way to keep the crops intact for tomorrow. The weather is humid.

Mu Xi handed her the half-eaten tangerine and took the water ladle from her hand.

"Green peel tangerine?"

Zhao Yeqing was a little surprised, but when he saw that only half of the oranges were left, he blinked, "Only one is ripe?"

Mu Xi shook his head, "There are still some in the basket."

I get it, it’s a bit sour.

Zhao Yeqing put the citrus pulp to the tip of his nose and smelled it. The unique fresh and sour aroma flooded into his nostrils, and saliva secreted rapidly in his mouth. He couldn't wait to taste a piece.

Sweet and sour and delicious!

The fruit pulp is juicy. I don’t know if it’s due to the fact that during the fruit expansion period, the high temperature just passed and there happened to be a heavy rain.

Small pieces of fruit pulp burst between the teeth, the sweet and sour juice burst out instantly, and the fruity aroma filled the mouth.

Unlike the soft flesh of sugar oranges, the flesh of green peel oranges is slightly crispy and tastes more like oranges with thicker pulp walls. It tastes very refreshing.

After finishing half an orange in two times, Zhao Yeqing couldn't get enough of it, so he went to get another one from the basket.

The sour taste in her mouth made her squint her eyes. Not every green tangerine can be 70% sweet. The one she opened was probably only 40% sweet.

Zhao Yeqing had a thought and moved next to Mu Xi, pretending to be nonchalant and raising his hand to feed him.

Mu Xi didn't want to eat it at first, but thinking that it wasn't too sour and it was Zhao Yeqing who brought it to his mouth, he still opened his mouth and ate it obediently.

In an instant, Zhao Yeqing saw Mu Xi's face wrinkled into a ball, and he turned around and ran away without hesitation.

Only a series of laughter was left to Mu Xi, who was confused on the spot.

Mu Xi, who was shaking from the acidity, swallowed the pulp in his mouth. He had no choice but to continue watering the fruit before he finished his work.

After finishing the work, I wanted to take revenge, but who is Zhao Yeqing?

On the dinner table in the evening was a large plate of sweet potatoes that Mu Xi had not been able to eat when he was injured in Yunwu Mountain.

This made Mu Xi laugh angrily, "Okay, okay, this is how you play, right?"

Zhao Yeqing blinked his eyes, as if he didn't understand what you were talking about.

Mu Xi could only pick up the chopsticks angrily and lower his head to eat without saying a word.

What can we do? After all, cannibals have short mouths.

From then on, Mu Xi refused to take a bite of the remaining green peel tangerines, and refused to open his mouth no matter how Zhao Yeqing coaxed him.

But even so, every time he refused, Zhao Yeqing would think of Mu Xi's wrinkled face.

Hahahahahahaha, laughing non-stop next to me.

Mu Xi snorted coldly, picked up the peel she had just finished eating on the table, took it out, washed it and dried it.

Dried citrus peels, whether yellow or green, can be made into tangerine peel, which is very good when soaked in water or used to prepare medicine.

After a month, almost all the tangerines were ripe, and Mu Xi picked them all.

In the end, Mu Xi, who was inexperienced, discovered that the citrus trees in the orchard were not of the same variety. The trees in the two rows were normal yellow-skinned tangerines.

I originally thought that the difference in fruit trees was caused by two different environments: being shaded by trees and being exposed to direct sunlight. I never expected that two varieties could be grown in such a small orange orchard.

Seeing that there are still yellow peel mandarin oranges, Zhao Yeqing will not use them to dry them to make tangerine peel this time, but plans to use all the peels of the yellow peel mandarin oranges to extract essential oil.

The peel of Huangpi Mandarin is relatively thick, which is most suitable for extracting essential oils.

Mu Xi thought that all essential oils were extracted by distillation. Zhao Yeqing explained, "Citrus and lemon are not the same. Extraction with high temperature and water will affect the activity. It is best to cold press directly."

This was mentioned casually by the teacher in the chemistry class before. She didn't know any professional techniques, so she could only use the simplest squeezing method.

Scrape off the white innermost meridian of the finished tangerine peel, and then squeeze the orange peel in a small pressing device.

For this equipment, Zhao Yeqing asked Mu Xi to make an ultra-small one based on the principles of their oil extraction machine, specifically used to extract orange peel essential oil.

Because it is not distilled at a high temperature and the storage method cannot be very hygienic, and there may be bacteria in the extraction process, Zhao Yeqing is not using it for people, but for plants.

Orange peel essential oil is very easy to use to kill red spider mites, and it is a natural ingredient and will not be harmful to the human body.

But to extract enough essential oil, you have to peel off the fruit skin.

So the two of them got a huge pot of citrus meat that they couldn't finish eating.
