Li Siyuan searched in his mind for the records of glue in the memories of his previous life, not to mention, he really let him find some, but considering the actual situation at the moment, he could only choose the cheapest and most convenient pigskin glue!

After Li Siyuan made up his mind, he didn't hesitate anymore, and hurriedly got up to find his mother, his mother should still be at Uncle Zhou's house now, although he didn't know the road, but this didn't affect him to find his mother, because there was a mouth under his nose.

This is Li Siyuan's first time out of home in this era, although he is only walking around in a small village, but he is still looking forward to seeing the scene of the prosperous Tang Dynasty, however, the reality is always cruel, the village does not have the green mountains and green waters in the TV series in the previous life, the scenery is picturesque, some are just some low courtyard walls and dilapidated grass houses, and even Li Siyuan also saw the traces left by the war from some walls!

He heard his mother say that this is a village close to Chang'an, named Li Jiaji, under the jurisdiction of Jingyang County, and traces of war can be seen in such a close place from the heart of the Tang Dynasty.

Li Siyuan inquired all the way to Zhou Butcher's house, Zhou Butcher's house looked much better than Li Siyuan's house, at least many of the furniture was not as old as Li Siyuan's house!

As soon as he entered the door, Li Siyuan saw two young men as big as himself in the yard, squatting there and shaving pig hair, he stood at the door and asked, "Excuse me, is this Uncle Zhou's house?" ”

The two who were busy shaving pig hair heard someone asking, raised their heads and looked at Li Siyuan, and then said with a disdainful face: "What to pretend, you don't know our family, you never regarded yourself as an outsider when you came here before, what's wrong now, is it stupid to catch birds?" You're polite to us! ”

As soon as Li Siyuan heard it, he knew that these two people must be old acquaintances of this body before he crossed over, and it is very likely that these two people were also involved in catching birds by himself!

Sure enough, as soon as the two finished talking, two women walked out of the house, one was Li Siyuan's mother, and the other thought to be the hostess of the house!

Li Siyuan hadn't spoken yet, but only heard the hostess scold: "Two cowards, don't they all blame you for breaking their heads, if it weren't for the two of you who went up the tree with the dog's egg, could he fall and fall?" Fortunately, the dog is safe and sound, and he was taught by the immortals in his dream, otherwise, it would not be too much for the old lady to kill you! ”

The two young men looked very afraid of their mother, stuck out their tongues at Li Siyuan, and then quickly lowered their heads and shaved the pig's hair!

Li came over while the woman was talking, took Li Siyuan into the courtyard, and explained the whole story to Li Siyuan as he went:

The two people who shaved the pig's hair on the ground are brothers, one is 15 years old, the other is 14 years old, both are the sons of Zhou Butcher, their names are Da Niu, Er Niu, the fat one is called Da Niu, and the second cow is slightly thinner. And that woman is the mother of Da Niu and Erniu, Li Siyuan has to call it an aunt, Zhou's temper is hot, and he usually beats his son less, so Da Niu and Erniu are more afraid of Zhou!

After listening to what his mother said, Li Siyuan glanced at Da Niu and Erniu with interest, it turned out that these two boys on the ground took themselves to skip class that day, and then went up to the tree to dig out the bird's nest, these two brothers look five big and three thick, but there are a lot of hearts, and they don't dare to go up the tree, so they encourage me to go up the tree, it's really unseemly! Li Siyuan slandered the two of them, and at the same time gave them a nickname in his heart: Brother Pig Hair!

After Zhou scolded his son, he beckoned Li Siyuan's mother and son to come into the house to drink some water, Li followed Zhou into the house, but Li Siyuan didn't go in, he came to the side of the big cow and the second cow, and watched them shave the pig's hair!

Seeing that his mother had gone back to the house, Da Niu Erniu moved the place closer to Li Siyuan, and then asked Li Siyuan secretly: "Dog, did you really break your brain?" Did the gods really pass on the immortal law to you in a dream? ”

Li Siyuan looked depressed, and scolded the two of them in his heart: You just broke your brain, your whole family broke your brain! Hungry, that's called soul loss, do you understand soul loss!!

Although there was a lot of resentment in his heart, Li Siyuan also knew that the two of them had no malicious intentions, so he nodded and admitted it!

When the pig-haired brothers saw that Li Siyuan had admitted it, they excitedly put down the razor in their hands, stood up, walked to Li Siyuan left and right, and squatted down, and then began to ask:

"What did the immortals teach you?" "Will you turn stones into gold and beans into soldiers?" "Do you know how to pierce walls?" "Do you know how to do invisibility?" "Do you know how to live forever?" .......

Every time the two asked, Li Siyuan had to shake his head once, and in the end, Li Siyuan was really scared by the question, and hurriedly stopped: "Shut up!" I don't know what you say, the immortals just handed me the art of Gewu, not the mess you said! ”

After listening to Li Siyuan's words, the pig-haired brothers showed a look of disappointment on their faces, and Da Niu sighed and said, "I thought you had learned some powerful immortal arts, but it turned out that you just learned something that I had never heard of!" It's really a disappointment, there is no wall piercing technique, let's peek at Widow Liu taking a bath in the future, and we have to climb the wall! ”

Li Siyuan was thundered by the words of the bull, it seems that this brother really did a lot of bad things before!

Seeing that Da Niu Erniu was disdainful of what he said about the study of Gewu, Li Siyuan looked at Da Niu Erniu with disdain, and said: "What do you two fools know, this Gewu is an all-encompassing science, if you can learn to learn fine, you will not be able to go to heaven and earth in the future, and the immortal arts you said are not worth mentioning in front of Gewu!" ”

Seeing that Li Siyuan had taught the doctrine of Gewu so powerfully, Da Niu asked suspiciously: "Is the study of Gewu really as powerful as you say?" Will you hand him over to us? ”

Li Siyuan said without thinking: "Of course it's true!" And I don't just teach you, I can teach anyone who is willing to learn Gewu! This is also the reason why my master gave me this knowledge, and he hopes that everyone in the world can learn the study of things, so that people can live a prosperous and healthy life! ”

Da Niu Erniu looked at Li Siyuan, and at the same time gave a thumbs up, and praised: "Your master is really great!" ”

Li Siyuan saw the flattering expressions of the two, and said angrily: "Okay, okay, you two hurry up and prepare the pig hair I want for me, and by the way, prepare two catties of pig skin for me!" ”

The pig-haired brothers were worried about Li Siyuan's immortal arts, so they naturally responded to their needs, and quickly prepared these things for Li Siyuan! Li Siyuan saw that everything was ready to stop, so he got up and called his mother home!

After Li came out of the house, he saw that Li Siyuan had a lot of pig skins in addition to a large bag of pig hair in his hand, thinking that his son was hungry, and hurriedly prepared to pay Zhou, Erniu saw this and hurriedly stepped forward and said: "Aunt Li, the dog is willing to hand over the immortal art he learned to us, how can we still collect your money for this pigskin!" Get your money back! ”

When Zhou heard Erniu say this, he was also overjoyed, and hurriedly refused the copper money that Li wanted to pay, and also sent their mother and son all the way out of the door, and the enthusiasm made Li at a loss!

Li Siyuan followed Li Shi for a few steps, as if he remembered something, turned back to Da Niu Erniu and said: "You two are not allowed to call me a dog in the future, I am older than you, you either call me brother or call me by my name, in short, if you call me a dog again, I will break off my friendship with you!" After speaking, he didn't wait for the two to agree, hurried two steps to catch up with his mother, and walked back together!

The pig-haired brothers glanced at each other and shouted loudly towards Li Siyuan's back: "Okay brother dog, we all remember!" After shouting, the two saw Li Siyuan stumbling under his feet and almost fell, and laughed together, and then they were driven back by their mother to continue shaving pig hair!

Without saying a word all the way, the mother and son soon returned home.

After arriving home, Li Siyuan began his great business of making toothbrushes, he first washed the pig skin and put it in a small clay pot, then washed the pig hair and put it into a larger clay pot, and then put the small clay pot containing the pig skin into the large clay pot containing the pig hair, and then covered the lid respectively, and began to prepare the steamed pig skin and boiled hair!

Li Siyuan steamed pig skin is naturally for glue, many carpenters in ancient times used pig skin glue or fish bladder glue, these two kinds of glue have many benefits, first of all, the most important is natural pollution-free. Secondly, these two kinds of glue are most afraid of heat, so when the furniture has been used for a long time and is damaged, you only need to use a pot of boiling water to pour it on the glue place, and you can disassemble it. And cold water, no matter how much you pour it, it's fine. Unlike the chemical glue used now, it is basically impossible to disassemble when glued, and the old carpenter also called the modern glue "desperate glue".

The reason for boiling pig hair is also clear at a glance, the first is disinfection, the second is to remove the odor, if the pig hair is not boiled, not to mention how many bacteria there are on it, just the smell, I'm afraid it can smoke and vomit!

When everything is ready, there is nothing to do, the process of steaming pigskin glue takes about two hours, as long as the fire is constantly in the middle, it is not complicated!

In this process, Li Siyuan and his mother made some small, thin pieces of wood, and after a while the pig skin glue was ready, it could be glued to the wooden handle of the toothbrush and clamped the pig hair!

Soon two hours passed, the pigskin had really melted, Li Siyuan and his mother took out the pig hair, washed it with cold water, and began to take advantage of the fact that the pigskin glue was still hot, while selecting the right pig hair, while only making a toothbrush!

The last process of making a toothbrush is a meticulous job, so after more than half an hour, Li Siyuan finally made the first toothbrush, but that is really not flattering!

Li Siyuan didn't care what it looked like, and when the pigskin glue cooled down a little, he hurriedly picked it up and tried it, he tried it while making a summary: there are still some peculiar smells, but it's acceptable, brushing your teeth is much softer than willow branches, well, you can use it, the appearance is slightly improved, it should be able to sell at a good price, but it's not easy to make!

Li Siyuan excitedly told his mother about the experience of the trial, but he didn't dare to say anything about selling it, Li nodded again and again after listening to it and began to make the second toothbrush, of course, at Li Siyuan's request, the shape of the second one looks much better, and both of them have experience, and the manufacturing is much faster!

Li Siyuan took the improved toothbrush and nodded again and again, but he was thinking about this in his heart, his mother didn't let him do business, how should he sell this toothbrush?
