That night, after Ding Qi had dinner in Jing, he asked Jing and his two men to come to his yard with a basket of meat and bones, light a fire in the yard, boil water, break bones, and prepare to boil a natural adhesive: bone glue.

Tinch had previously made two kinds of adhesives, one was the kind of binder that sticks bird feathers to the arrows, using a substance formed by mixing a white milky liquid from the roots of pine resin and dandelions. There is also a kind of writing, that is, the words on the plaque on the city gate, which are adhered by bone glue. At that time, Ding Qi didn't let others intervene to help, but just boiled it there himself. Now Ding Qi shouted Jing up, and Ben, who was ready to come over, let them study together.

Bone glue boiling is hard work, and like wool making, the bones need to be treated with lime water.

First, use a brush made of wild boar bristles and a bronze knife to remove all the debris from the meat bones, such as minced meat and carrion, fascia, etc. The bones are then smashed with a stone hammer, a stone axe, or a bronze axe to remove the marrow and other contents from the inside. Then soak and stir these broken bones in hot water sprinkled with lime to further remove the debris and grease on the bones, and at the same time neutralize some acids on the bones, which play a role in softening bones and making osteoporosis.

After these are done, the softened broken bones are taken out and drained, and then enough hot water is added to the clay pot, at least the amount of water that can extract all the gum in the bones, Ding Qi generally chooses 1.5-2 times the amount of water.

A bamboo grate is added to the clay pot, a clay bucket-like cage drawer is filled with broken bones, and a lid is added, and a heavy object is added to the lid to prevent the lid from being pushed open by steam. The main function of this heavy object is to keep the cage drawer in a closed environment at all times, to put pressure on the bones in the steamer, and to extract more gum from the bones.

Bring the water to a boil over high heat, then change to medium heat and steam slowly. In this process, the gum in the bones is constantly precipitated and flows into the hot water below, where it slowly merges. When the steam starts to decrease, change the firewood to low heat and steam it.

Half an hour later, take out a bone from the cage drawer, and if you can easily pinch the bone into pieces, it is basically settled. Then remove the cage drawer, bones, grate, etc., and use a clean wooden stick to stir the remaining extract in the clay pot, which is the bone glue mixture. Stir constantly, slowly dehydrate, and finally change to a simmer for drying, and finally get bone glue.

Since there was a carpenter in Dingqi's neighbor's house, the method of bone glue was also obtained from this craftsman's hand. In the past, carpenters in rural areas rarely used iron nails to make furniture, and they all used mortise and tenon structures and bone glue to make the furniture strong and durable.

At that time, Dingch was particularly interested in these, and the carpenter said that he was an unborn strange man who could accept the mantle of a carpenter. If it weren't for his family's opposition, Ding Qi would have really followed others to learn carpenter's life.

It's just that when bone glue is used, it needs to be heated with water before it can be used, and the ratio is basically one to one. And the heating temperature should be kept constant, about 70 to 80 degrees, so that the prepared bone glue can achieve the best effect when sticking to the wood, impervious to water and breathable. Of course, the best level depends on the experience and needs of the master carpenter.

After a busy night, Ding Qi finally showed Jing and Ben the process of making bone glue, and at the same time mixed and used the prepared bone glue. Jing was so pleased with the results that he danced with joy and prepared to immediately go to the carpenter's shed to make another model of a fishing boat to see the effect of bone glue. As for the issue of wood waterproofing, he didn't think about it for the time being, because this was something that the leader needed to consider, as long as the leader found it, he just used it.

Ding Qi hurriedly grabbed him and asked him to go with him to breakfast, and then go to sleep before going to work. After tossing for a night, I am already very tired, let alone Jing? Didn't you see that Bendu had been yawning there all the time, and the other two men who had fallen asleep on the ground?

Under Ding Qi's coercive order, Jing Cai reluctantly

Go to eat and sleep.

What about Ding Qi himself? The same is true, hugging the little cutie who has been busy with him all night and sleeping until noon.

The weather is getting hotter and hotter, and although sleeping in a brick house can get rid of a certain amount of heat, it still can't stop the invasion of heat, not to mention the constant chirping. I've been busy with tribal things lately, and I don't even know when I started calling.

He had just crossed over last year, and a fire had burned vast forests and grasslands to ashes, and Ding Qi had not heard a cry all the way. By the time we reached the lake, the weather was getting cooler, the sky was full of smoke and clouds, and the surrounding woods were inaudible.

Unexpectedly, when the weather was normal and summer came, their group of elves nesting in the dirt began to come out to join in the fun. It must be said that this group of creatures who have been living for hundreds of millions of years are quite keen.

The weather was hot, and it was lunch break in the tribe, and even four pergolas were built on the city walls to protect the warriors on duty from heat stroke. Ding Qi estimated that the temperature was about twenty-five degrees, which was not too hot. Ding Qi didn't know how much the maximum temperature would reach, but he knew that the primitive people in the tribe couldn't stand such temperatures anymore.

Ding Qi asked Ben and the buck if there was a hotter time than now, Ben said he didn't know, and the buck said that there were times when it was hotter than this before, the grass and trees on the land dried up, and the river flowed out, which should be regarded as the dry season in the great wilderness.

Since you think of it, you won't forget the deliciousness when you just climbed out.

Recently, I have been so busy that my feet do not touch the ground, and most of the farming matters have been taken care of, except for the rice that has not been planted. Ding Qi saw that there was nothing else to do, so he simply went to the leatherman Niu Er and found a peeled deer urine bubble.

Niu Er is researching how to make water bags from animal skins, and has changed a variety of animal materials, but still hasn't found a suitable animal skin. Now the tribe has not tried three kinds of horse skins, sheepskins and reindeer skins. According to the number of water bladders used in the Mongolian steppe, Gobi and desert, sheepskin and horse skin should be the most, and it is most likely to be soaked in sheepskin and sheep urine. The sheep sacrificed during the previous celebration of the founding of the city, the urine bubble has long been lost. At present, the number of sheep is still small, and there is no scale, and when there are flocks of sheep, batch trials or water bladders can be made.

Ding Qi looks for deer urine bubbles and prepares to make a net that has been caught.

This oval-shaped urine bubble has been concocted, very thin and translucent, like a frosted plastic bag, truncated from the bottom two-thirds of the way. Then he went to the carpenter group to find a half-centimeter-thick bamboo stick and circled it in a circle. Now in charge of the craftsman group is Butterfly, Ding Qi didn't expect that she was very talented in bamboo weaving, the bamboo made is very beautiful and sturdy, not to mention, but also constantly turned over tricks, so that Ding Qi, a young man in the 21st century, is a little embarrassed.

Using the tools of the carpenter's team, Ding Qi rolled the urine bubble on the bamboo circle, turned it over, took a bronze needle to drill a hole in it, and then tied the urine bubble tightly with a thin thread to form a bag with a small mouth and a narrow bottom, just like the aluminum pot used for cooking in the countryside in the past.

The ring is then tied to a long bamboo pole and fastened with three thin bamboos. In this way, a net that has been caught is ready.

Ding Qi finished his work, wiped the sweat on his head, looked at this satisfactory work, he grinned, and was about to step out, when he raised his eyes, he saw Lu smiling and coming over.

"My Lord, what are you doing here?"

The deer flicked his ponytail and asked with some curiosity.

Ding Qi pointed to the Zhiwang in his hand, and said a little ostentatiously:

"Huh? It's a kind of net that catches small animals, can you guess what kind of small animals are catching? ”

The deer tilted his head and thought about it, blinking his eyes and guessing:

"Butterflies?"

Ding Qi shook his head:

"No, but soon,

Flying like a butterfly, you're definitely right to think in this direction. ”

The deer thought about it again, and then there was a cry of knowledge, and her eyes lit up:

"Understood, is it a monkey? Right? ”

"Haha, the deer deserves to be the tribe's doctor witch, so smart! That's right, let's go, brother will take you to catch it! ”

Ding Qi was very happy to see that the deer had guessed correctly, and couldn't help but step forward and scratch the deer's nose, and suddenly made the deer's face like a ripe peach.

Ding Qi's heart trembled, and he felt the urge to step forward and hug the deer and kiss him. But take a closer look at the other party's current age, think about it, forget it, it's still a big Lori, bear with it! The melon is a little astringent, and then eat it when it is ripe, sweet!

The impulse was resisted, but Ding Qi still stepped forward, regardless of it, took the deer's hand and walked towards the east gate, where there were many trees and knew a lot. Passing by the cafeteria, I didn't forget to take a small deerskin bag, ready to hold the catch of it. It's just that his mind doesn't seem to be on walking, and he hits the wall twice in a row. Even the little cutie who followed him was a little puzzled, and looked at him with incredible eyes from time to time.

But Ding Qi, who was immersed in it, didn't know that it was sweet there, and he kept saying in his heart that the hands of this primitive chick were as tender as boneless, and they were reluctant to throw it away.

Coming to the edge of the forest, Ding Qi was full of energy, ready to show his superb level in front of the little girl in front of him, and see how she admired herself.

But when he turned his face to look at the tree, his face suddenly darkened.

I was afraid that I would not know enough, so I found the longest bamboo pole. But who would have thought, these are a little shameless, all lying on the top branches and leaves, and none of them can reach themselves.

I want to show my hand in front of the little girl, but it's good, I can't reach it! Isn't that a slap in the face?

However, Ding Qi was not discouraged, smiled at the deer, relieved the embarrassment just now, turned his head and went to the forest to find the knowledge that he could get.

I don't know if the primitive world knows like this, or if they have discussed it collectively, and they are all at the top, so that Ding Qi came with hope and returned disappointed. Every time they fail, those who know will raise their voices in vain, "know, know" and shout, as if they are laughing at Ding Qi.

No, the bold guy began to tease Ding Qi, slowly moving his body downward, calling as he moved, as if shouting there:

"Come on! Come on! Come and get me! ”

Ding Qi didn't know what they thought, he just knew that his chance had come.

Gently lifted the net high, and slowly moved towards the black Zhizhi that was still ringing, getting closer and closer. Knowing that there is no reaction, it seems that it has focused all its attention on how to attract the opposite sex.

Ding Qi smiled smugly in his heart:

"Look where you're going! Eat me in one net! ”

When he was still twenty centimeters away, Ding Qi suddenly waved the bamboo pole and aimed the net mouth of the Zhizhi net at the Zhizhi and waved it down.

Boom!

"Squeak~"

Ding Qi, who was bound to win, threw himself into the air and let the little guy escape. Immediately after that, under the sunlight, a canopy of mist shone with colorful light, enveloping Ding Qi under the tree, drenching him all over his face.

Tinch's face is even darker!

Before flying, he brought a gift to Ding Qi and knew that he was urinating!

"Giggles, the leader brother is so stupid!"

The sound of laughter like silver bells sounded, which made Ding Qi a little embarrassed, wishing that he now had a pair of wings and could fly up and catch these little ones with his net.

"Humph! Look at me! ”

Swing the net!

Squeak~

Swing the net again!

Squeak~

Three swings of the net~

Squeak~
