I live in prehistoric
Chapter 27 Weaving Nets
After "enlightenment" last night, I spent a lot of time, reviewed Xiangzi's homework, and then fell asleep.
When Gong Xi opened her eyes in the morning, what she saw was Xiangzi's pure and beautiful sleeping face, her mind fluttered for a while, and she went to wash up after counting his eyelashes.I took off my shirt and wiped my body, and found that my arms and chest seemed to be firmer, and I couldn't restrain the joy in my heart.Raising her arms, she made a bodybuilder gesture, and was turning her head to inspect it, when she saw Xiangzi staring at herself with her upper body straight and wide-eyed...
Oh, how embarrassing! "Xiangzi, good morning!" He greeted.
Xiangzi had an intuition not to laugh at this time. Gong Xi's small body has indeed become a little thicker recently, and he should be recognized and encouraged.He got up and walked to the depressed and embarrassed Gong Xi, beat his chest lightly, and said with a smile, "It's getting bigger, it's great!"
Gong Xi clutched her chest and watched him go out to find the toilet, the corners of her mouth twitched uncontrollably.Got bigger?What the hell!
In order to make writing paper and start the era of fishing fun belonging to Xiangzi and others, Gong Xi decided to take the lead and try to weave fishing nets.If the fishing net can be made into a shape, there is hope for the filter net.
Xiangzi was braiding the rope on one side, and Gong Xi arranged the rope at an angle of about [-] degrees into two sets of parallel bundles, crossing each other with a distance of half a finger and tying a knot every time.
If this is a big net, the rope alone can't afford it!Gong Xi temporarily gave up the huge fishing net and decided to make a fishing cage first.
The opening of the wrapped net is made of tough and moderately soft and hard bark, and it is tied with a long reinforced rope, which can be thrown directly into the water.Gong Xi couldn't wait to encourage Xiang Zi to go to the sea together...
On Gongxi Road, Fei Shi'er was called to go "sea fishing" together.
This time, I felt a little relaxed and looked at the sea.The sun is good, and the water is glowing with golden light, giving people a particularly open and comfortable feeling.Facing the endless sea, Gong Xi opened her arms and raised her face intoxicated.
Fei Shi'er imitated everything, and unfolded his immature body.She heard the surging impact and the gurgling flow, the warmth from the sun and the coolness from the sea breeze.
Seeing the same movements of the big and the small, Xiangzi turned her head with a smile, swung the net bag around vigorously, and threw it forward vigorously.It flew up along a parabola, fell, and sank into the water, and the rope on Xiangzi's arm was quickly tensed.
Regrettably, Gong Xi missed Xiangzi's projection, so he had to find a big rock and help him tie the rope to it.
"Only shredded pork, no customers~"
"Rose and Jack? Titanic? Very old movie!"
"Xiangzi's desire to catch fish is stronger than hugging from behind..."
"The little girl is here, it's not good to hug~"
In fact, I just regret that I didn't see Xiangzi's heroic appearance. These little tricks... Of course, it's very good to have them!
"Uncle, do you know?" Fei Shi'er opened his mouth softly, "I was quite afraid of coming here. Mother told me before that when I was a little older, they almost abandoned me... a lot of people I will throw the child into the water. If it is better, give it to someone to hold it, and maybe it will live longer..."
It's a horrific and tragic story indeed.Gong Xi felt that she could no longer look directly at the sea surface and the fish in the water!
"...Suddenly goose bumps all over my body!"
"Fei Shi'er, you scared me!"
"Think about it, actually... this is very real."
"I looked at Gong Xi and his face turned pale. I probably won't be able to eat the fish even if I catch it!"
He knew that some things should not be overly complicated, and he had to connect them together, but he still couldn't adapt for a while!
Xiangzi walked closer to the water surface, the wind lifted his long hair and the hem of his clothes, and his trouser legs bulged and danced continuously.He is like a fairy who came and went back by stepping on the water. Gong Xi vaguely recalled the image of Donghua Shangxian who was obsessed with him when he was a child, and felt that Xiangzi was very chic and elegant at the moment.
The surface of the water will always be like this, no matter what hides in it, no matter how much hope or cruelty is left behind, it has never changed.
He felt that the appearance of the palace seal was like a gift from heaven, which changed his life of being at a loss and not knowing why.One day, Gong Xi disappeared completely, did everything go back to the way it was before?Where did he come from, is it farther than the place where Tianhai communicates?
Gong Xi hugged Fei Shi'er to her chest, letting her tears have a destination.
The little girl's eyes were red, and she didn't want to cry at first, but the moment "Uncle" hugged her, her nose became sore... She had never cried like this in front of her parents, only... Daddy wanted to send her away When she is, it is sad.
Xiangzi came up behind him, covered his cheeks that were hot from the wind, and buried her head in the socket of his neck.I am very reluctant and want to tie him up, but I know that I must let him go!
When the fish came into the net, Fei Shi'er took them to the field to have a look.The reason why it is called "land" may be that they think there are more things to eat there.Gong Xi still knew the mulberry tree, but when he saw the fat worms of different sizes and colors lying on it, he felt as if something was about to come out of his throat, and he couldn't bear the physical disgust anymore. , turned around and jumped away.
"Fei Shi'er, uncle has no choice but to point at you!" Gong Xi looked at the little girl with a confused expression, and finally gave up on this sacred exploration.Xiangzi seemed to understand something, the corners of her mouth raised suspiciously.
"Is Xiao Gongxi afraid of bugs?"
"I'm afraid too..."
"Inexplicably, I feel that Xiao Gongxi is so cute!"
"Xiangzi is laughing at him~"
Feeling quite humiliated, Gong Xi crouched on the ground to pick up vegetables, waiting for the two to come over.
"Uncle, don't you like it?" Fei Shi'er asked.
Gong Xi raised her head and saw the finger-long worm curled up in the little girl's palm, and she sat down on the ground.Fei Shi'er, uncle... Brother really loves you for nothing!
Xiangzi stepped over to lift him up in two or three steps, and patted the dirt on his butt... It was really embarrassing.
"That...it's useless for you to keep it. It's a picky eater, and it doesn't eat ordinary vegetables." On the way to collect the net, Gong Xi kept a distance from Fei Shi'er, and told him what he knew. Tell her all the knowledge about silkworm rearing.
"Fei Shi'er has become mischievous too~ Relying on my uncle to spoil her~"
"In an instant, I fell from a group favorite to a group bully, and I feel sorry for Xiao Gonggong for three seconds!"
"Paper was invented because of hemorrhoids, and silk was not invented because of fear of insects... Is this okay?"
"It's the truth upstairs!"
Gong Xi left a message: I don't have hemorrhoids, it's just prevention!
Xiangzi pulled the rope and wrapped it around her wrist, she leaned back and the net bag finally surfaced.Gong Xi and Fei Shi'er temporarily forgot the sad past in Haili, and rushed over to check it out.
The rich treasures in this sea have not been excavated, and seven or eight sea fish were caught on the net just from the fishing cage for testing the water, which really surprised everyone.
"Congratulations! Sprinkle flowers~"
"I'm #% (block words), so much to eat again!"
"It's time to dry the fish..."
"Is it that easy to catch fish?"
"Naturally there are more fish than we have now, and fishing is banned every three days!"
Not to mention everyone's joy, after returning home, Fei Shi'er was in charge of stewing the fish, and Gong Xi helped to plant green onions and vegetables next to her house and her own house, for the convenience of eating in the future.
Intentionally or unintentionally forgetting the previous rumors, the two families got together to eat a seafood meal and shared the latest "new things".The man said, now that the weather is warm, it is time for the old man to go hunting.So the three men entered the mountain and walked into the depths.
Gong Xi followed them into the mountain, still feeling a little apprehensive.He didn't know what he could do to help, maybe it's more likely to happen things that are slow, and those with bad deeds... But Xiangzi and Hanzi didn't say they wouldn't let him go, and his self-esteem couldn't make him take the initiative to say: Then I won't go...
It's just that this time it's really not so coincidental, except for a few sporadic prey, they didn't find any traces of large animals or wolf dogs.The rumored residence of the old hunter was also nowhere to be found.
There are no roads in the mountains, the trees are overgrown, and the thick leaves are very difficult to step on.Fei Shi'er's father was too tired to take it anymore, he leaned on the tree to catch his breath, and shouted depressedly: "This old guy can hide! If I catch his dog son, I will roast it and eat it!"
A howling sound like a wolf came from a distance, and the three of them turned serious and cheered up to chase after it.I went around again, and I didn't even see a dog hair!
All three of them felt that people and dogs were probably avoiding them, and that it was going to be dark, so they had to go out first.
"It's really a good place to hide and seek!"
"This nervousness will scare the baby to death!"
"Mysterious and mysterious, so it's not so easy to find!"
"Xiao Gongxi seems to be holding on to the corner of his man's clothes all the time?"
"Hey, I just noticed..."
Almost out of the mountain, Gong Xi's hanging heart finally returned to its original position.There was another long howl, and Xiangzi looked at him with a wry smile.
The man was so angry that he cursed again: "Old guy! You have a weird temper! If you have the ability, don't come out for the rest of your life! Die inside!" He sighed "bad luck" along the way, and didn't mention when he would go in again.
After taking a shower and washing their clothes, the two of them blushed, neither daring to think about shame.After kissing and hugging, we chatted for a while and then fell asleep.
It rained the next day.The rain fell on this community with a cold feeling, and the autumn colors became more intense, and most of the forests in the distance seemed to have withered and turned yellow overnight.
Gong Xi lay on the bed in Xiangzi's arms, even though she knew that the sky was dark and the earth was only rainy, she didn't want to get out of the bed.
Xiangzi, who has always been diligent and self-disciplined, also lay down with him, only feeling satisfied with Gong Xi's head hanging on her chest.
The only thing that can overcome laziness is the desire to defecate... Finally, Gong Xi hurriedly put on his clothes and slipped into the rain curtain, experiencing the hearty convenience of being out in the open air before, thinking about things, silently blushing.The man's boobs and the hugs and all, it's just obsessive.
Xiangzi ran into the house nimbly, Gong Xi was sitting at the door staring blankly, now she was looking at him.
Gong Xi patted the bench beside her, and Xiang Zi sat down obediently, looking at the gloomy sky and the continuous drizzle outside.
"It's raining!"
"It's raining!"
"It's natural rain! I've never seen natural rain before!"
"The most recent one was 25 years ago... But, does it look different?"
Wiping his half-wet long hair with a cloth, his crooked head gradually leaned against Gong Xi's shoulder.At this moment, Xiangzi is so well-behaved.If it were in modern times, he would only be an adult, so he should still look childish.
Gong Xi plucked up her courage and hugged Xiangzi's shoulders.Although his figure is strong and muscular, Gong Xi thinks he is soft and cute...
"Is it raining for you to fall in love?"
"Shouldn't you work in the rain?"
"Do you have to hug and hug in front of everyone?"
"When the weather is good, you are sweet and sad! When it rains..."
"So you guys plan to hang out all day?"
It would be nice to stay together like this all the time, if possible!
Until the stomachs of the two hummed back and forth, and they looked at each other awkwardly, it was time to cook.Xiangzi kissed Gong Xi on the lips, then turned to light the fire.
The confused broadcaster touched his lips and was obliterated by the barrage.
The author has something to say: 1. The difference between a lake and a sea: a lake is a body of water inside the land, and a sea is the part of the ocean that is close to the land.
2 Sericulture is an important skill created by the working people of the Han nationality in ancient times. According to legend, the method of planting mulberry and raising silkworms originated from Leizu, the wife of the Yellow Emperor.The ancestor of the silkworm is considered to be the wild silkworm (B. mandarina), which has almost no difference in shape from the silkworm, and can naturally hybridize with the silkworm after growing up to produce offspring.There is a silkworm variety called "Qingbai", which is said to be a hybrid of wild silkworm and silkworm.The number of chromosomes in wild silkworm is n=27, and that in silkworm is n=28. It is believed that silkworm is produced when one chromosome of wild silkworm is cut into two during the evolution process.
Before the Xia Dynasty, the domestication of silkworms existed, and silkworms were selected from mulberry pests, creating a sericulture technology.
3 Silkworm colors and corresponding varieties:
Silkworms are white.Also known as the silkworm, it is one of the economic insects that spin silk and cocoon with mulberry leaves as food.Belongs to Lepidoptera, Silk Mothidae.Mulberry silkworm originated in China. Its development temperature is 7-40°C, and its breeding temperature is 20-25°C. It is mainly distributed in temperate, subtropical and tropical regions.
Tussah, yellow.Silk-spinning and cocooning insects that feed on oak leaves.It belongs to the order of Lepidoptera and is native to China.The growth temperature is 8-30°C, the suitable temperature for growth is 11-25°C, and the optimum temperature is 22-24°C.Mainly distributed in China.
Castor silkworm, green.One of the economic insects that spin cocoons that feed on castor silkworm leaves.It belongs to the order Lepidoptera and belongs to the family of the family Mothidae. The castor silkworm is native to Assam in the northeastern part of India. It was spread from India in the 18th century, China, the United States, Sri Lanka, Malta, Italy, the Philippines, Egypt, Japan, North Korea and other countries. Successively introduced and raised.
4 Regarding Ma, I have been brooding about it for the past two days, wondering if I used the wrong materials.Ramie originates in China, and in the Neolithic Age, ramie fibers have been used as textile raw materials.The ramie cloth unearthed from the Mawangdui Han Tomb in Changsha City, Hunan Province has been very finely weaved.It is a famous specialty in China and is known as "Chinese Grass" in the world.Linen is also very old, but it was introduced to China very late. □□It has been planted since at least the Han Dynasty. It can be used to make cloth, refine oil (for paint), and be used as medicine.
