After lunch, they dispersed to prepare.

Qin Huaidao came to a blacksmith shop, and inquired, bows and arrows are contraband, and they are not allowed to be sold publicly, so they can be done secretly, but they have to be ordered in advance, Qin Huaidao saw that the shop had a rope made of cow tendons, and it was best to use it to make bowstrings, so he bought it.

Back to Qinjiazhuang, Qin Huaidao first looked at the construction site, a warehouse is on the wood, once the wooden board is nailed, covered with tiles can be used, the lime placed in the open air has a place to store, several brick-burning, lime-burning kilns black smoke billowing, burning charcoal is not idle.

More far, countless people pulled the stones over, talking about something, their faces were full of smiles, in this cold winter is particularly dazzling, in the open field next to a large pile of stones, two hundred people are nervously and orderly making honeycomb coal, the good stacks are neatly placed, and the rows are gratifying to look at.

When Jia Youcai heard the news, he rushed over and shouted excitedly: "Young master! ”

Three months ago, the house was still worried about the lack of money, the man was ready to leave, leaving the chance to live to women and children, but he didn't expect to have such a big family business today, it looked like a dream, every day, hehehe, seeing that Qin Huaidao was looking at honeycomb coal, he explained: "Young master, those coals were stepped on overnight by finding a few donkeys at night, and I didn't dare to let everyone do it, and the formula couldn't be passed on." ”

Honeycomb coal is just coal and clay, not a formula, but people who don't break this era really don't know, Jia Youcai is a treasure, and would rather let the donkey on the Zhuangzi step on it, and make good slime, rather than let the people of Zhuangzhuang touch it, Qin Huaidao understands Qin Huaidao's thoughts, although he doesn't care, he still respects Jia Youcai's choice.

Jia Youcai continued: "Young master, they want to light briquettes to keep warm, and ask if they can exchange things for them?" ”

"What do they want in exchange?" Qin Huaidao became interested.

"What they mean is that whatever the young master wants, as long as they can get it, they will get it."

Bartering is very common in the lives of ordinary people, however, the people's homes are so poor that rats don't patronize them, there are nothing valuable, it is estimated that they want to see what they want, so they go to find it, there is no fruit on the mountain in winter, wild beasts cannot be found, there is no food in the field, there is nothing to trade, Qin Huaidao looked ahead and thought, but he has the heart to help everyone, but he can't lose money, right?

Suddenly, Qin Huaidao's eyes fell on the straw not far away, which was used to start a fire, this thing is a lot of people in their homes, and they usually use it to burn the fire for cooking, and the endless pile of fields is burned as fertilizer, this kind of thing has a lot of fibers, and it is a material for making paper.

After coming to Datang, Qin Huaidao's most painful thing is to go to the toilet, there is no paper paper, you can only use the toilet chip to scrape, to put it bluntly, it is wood chips or bamboo chips, that is called a sour cool, before running around, busy and not taking care of it, after a period of leisure, you can try to make some hand paper, straw is a good material.

Thinking of this, Qin Huaidao said: "Ten honeycomb coals for a penny, you can let them exchange straw." ”

"Straw? That thing is worthless, every family has it, what is the young master doing with it? ”

Qin Huaidao was embarrassed to say that it was used to make tissue paper, in the concept of the common people, paper is expensive, how can it be used to wipe the buttocks such filthy things? said: "Do it, pile up the warehouse after collecting it, pay attention to fire prevention, waterproofing, I need to go out for ten days tomorrow, what else needs to be decided on the village?" ”

Jia Youcai pondered that Qin Huaidao was pitiful for everyone, and he was embarrassed not to accept anything for the briquettes, so he casually ordered straw to offset the number? It should be like this, no, this favor has to let everyone know that the young master is merciful, and everyone can't help but be grateful.

Thinking of this, Jia Youcai agreed: "Okay, just exchange it for straw, this thing is worthless, almost no one buys and sells, I don't know the price, the young master gives a price, and the old man goes back to handle it, in addition, the village is working, and there is nothing big at the moment, but the young master doesn't know what happened to the cement burned." ”

"I'll go back and see, as for the straw pricing, you can negotiate the price with the person in charge of each village, you can't let everyone suffer a loss, there are a few people who make honeycomb coal, I estimate that the number of people pulling coal will increase next, and you can let Uncle Ma make some molds again, you can't let the coal pile up like this, in case it rains, it's very troublesome."

When Jia Youcai heard this, he felt more and more that his guess was right, the young master was doing a good deed, and he couldn't let everyone lose, but he couldn't let the young master lose, the price had to be reasonable after all, and he promised: "Don't worry, young master, I'll let people go back to the house and say goodbye." ”

The two chatted for a while about other things in the village, Qin Huaidao came to the small kiln where the experimental cement was experimented, burned for two days, and started to heat it, Qin Huaidao climbed up to the mouth of the kiln to see, the stones inside began to turn red, and he didn't know if it would work like this, and told the guard in charge of the fire: "Be sure to record the changes, record them every hour, and I will check them when I go back, in addition, the things inside are not burned, they have to be melted, burned like water." ”

"Remember!" The other party hurriedly agreed.

Qin Huaidao didn't know if it was right to burn it into a liquid state, burn it first, at least it would be simple to burn it into a liquid and grind it in the future, I haven't burned it, let's try it.

"I may not be there when I go out of the kiln, I must cool it for a day or two, I must wear a mask when I go out of the kiln, if the mask is not enough, I will find Mingyue to make some more, and store it in the warehouse after taking it out, and I can't mix it with other things, and I must not see water, I can't go out of the kiln on a rainy day, and then burn the second kiln after I come back to see it."

"Remember, young master!"

Qin Huaidao observed for a while, and then asked about the situation of the burning in the past two days and left, he had no experience, so he simply didn't interfere, and everything was waiting for the burning to come out.

When he came to the place where the coke was burned, he asked the responsible guard to help decorate the coke and send it to the iron shop, just as Xue Rengui was patrolling nearby, so he shouted: "Brother Xue, come here." ”

Xue Rengui hurriedly ran up: "Young master, what are your orders?" ”

"I promised to give you a bow, I went to Chang'an City to ask, there is no ready-made, it needs to be ordered, at least a month, it's too slow, I'll help you fight, you come and fight." Qin Huaidao explained, striking iron is the most laborious, but Xue Rengui is born with divine power, and he can ask at any time if he has any needs around him, just right.

Xue Rengui knew Qin Huaidao's smelting strength, the horse lance made of stainless steel, and the knife were all sharp and unheard of, and when he heard that he wanted to help him build a bow and arrow, he was immediately overjoyed, and promised with a mouth: "Thank you, young master, let the young master bother." ”

Who doesn't want a good weapon for those who practice martial arts?

"It's okay, you can test the strength at any time by your side, ordinary bows are useless to you, you have to be by your side, let's go." Qin Huaidao explained.

When he came to the iron shop, Qin Huaidao found a thick iron bar, started the furnace, burned it with coke at a high temperature, and the iron bar burned red quickly when he put it in, and took it out for forging, and needed to remove the impurities inside, which was the most time-consuming and laborious.
