The weather was good in the next few days, with sunny weather and high temperatures day by day.

With the help of the old and young people in the village, Chen Xu's new house is also slowly taking shape.

During the day, women and children helped clear the weeds and thorns on the ground. Men went to the river beach to pick up some stones of similar size and came back to build the foundation.

Chen Xu, the pine wood that had been peeled off, was also made with an axe and a saw, and the cross-connection parts were moulded, and the tied green vines were all ready.

Although he had never built a house, this simple straw shed didn't need much brains to worry about. Just lay the framework firmly and make sure it didn't fall down. As for ensuring warmth and comfort, the technology and technology are not up to date. There are no red bricks and green tiles now, and there are not even Xianyang, and that kind of residence is not what he urgently needs now.

He had to repair the house before the summer rainy season arrived so that the family would have no place to sleep.

While Chen Xu speeds up the speed of repairing the house, there is also a blacksmith in Qinghe Town, twenty miles away, who is speeding up to build something.

The fire in the blacksmith shop was red. The short and strong middle-aged blacksmith took a small hammer. The two apprentices kept beating a red bronze product with a sledgehammer. They had a very clear shape, which was a bronze hand saw nearly one meter long.

Since seeing Chen Xu make a small change in the effect of the bronze saw a few days ago, the blacksmith seemed to have discovered a new continent, so he has been thinking about creating a brand new copper saw these days. After several days of research, the hand saw is almost successful.

Among the jinglings, red Mars flew around like fireworks.

This hand saw is nearly thirty centimeters longer than the previous hand saws, and the back is thinner and the blade is finer. The bronze used is also the most tough and strongest variety. In the past, it was used to create the sharpest weapon. However, for this hand saw, the blacksmith also spent a lot of money on his best copper ingot. This copper ingot came from Nanyang County City a hundred miles away. It was bought back and spent a lot of money.

"Swish~"

As the hammer stopped, the dark red copper saw was placed in cold salt water to quench, and a thick mist of water rose into the air. When the copper saw was taken out of the water, it was already a complete bronze hand saw, except for the jagged serration and blunt serration.

The blacksmith took the hand saw and squinted his eyes and looked at the two rows of saw teeth slightly apart on both sides. He touched each saw teeth with his hands next to each other. Then he gave a satisfied command, "Get my sharp knife over!"

A sharpening knife is a triangular cast iron tool. Because it is made by directly pouring the melted cast iron into a long ridge-shaped stone groove, the surface is as rough as a sharpening stone. Although cast iron is fragile, it is better because it is hard and much harder than bronze alloy. Using this cast iron sharpening knife to open the edge of the weapon is the best choice, especially a saw with many teeth and dense tools, ordinary sharpening stones cannot be polished at all.

Half an hour passed, and under the polishing of one tooth by the middle-aged blacksmith, each tooth of the bronze long saw became extremely sharp. Then, it was installed with a hardwood handle that had been made, and wrapped with thin hemp ropes next to it. A complete hand saw was successfully completed.

"Carry a thicker piece of wood!" The middle-aged blacksmith nodded with satisfaction and ordered.

After a while, the two young apprentices raised a thick wood with a diameter of two feet was placed on a wooden rack. The blacksmith stood in front of the wood with a copper saw in hand, put down the saw and took a deep breath and pulled the saw.

"Puchi pudchi~"

As the hand saw moved back and forth, fine wood chips fell down like snowflakes. The wood was quickly sawed and a neat gap several inches deep. After a few minutes, with a click, the thick wood was sawed into two pieces and rolled down.

"Haha~Hahaha~" the middle-aged blacksmith laughed excitedly and went out with a saw.

The reason why he was so excited was because of Daqin's reward for craftsmen's innovation.

The Qin Dynasty established its country with agriculture, which not only rewarded farming, but also rewarded inventions that were of great help to farming and production.

Once this saw is officially recognized as having great value for use and innovation, it will not only be recorded on the craftsman's list and reported to the county magistrate, but it will also be spread throughout the country and eventually become a national standard.

Everything in the Qin Dynasty today has standards. For their blacksmiths, there is no special requirement that even a hatchet cannot be made randomly. They must be made strictly in accordance with the official size. Each one must have a name on it, that is, the name of his own name or even the origin of the item he has made must be engraved on the knives he has processed must be marked with the inscription "Qinghe Town Ancient Mountain" on the knives he has processed. Qinghe Town is the place name, and the ancient mountain is his character. Once the knives are not of good quality, they will be complained to the government, and in the end the government will cause trouble. At the least, the compensation will be paid, and at the worst, the qualification of a craftsman will be cancelled. If the consequences are very serious, they will be deprived of their household registration and act as an official slave.

If a new and useful tool is invented and officially recognized, it will not only bring honor to the ancestors, but also have a more direct benefit that it can exempt a lot of taxes and corvee, but also improves its social status a lot. It will become a well-known craftsman in the county town or even the county government. The items they create in the future can be engraved on the ancient mountain of Zhixian County or even the ancient mountain of Nanyang.

Among the four ancient classes, scholars, peasants, industry and commerce, the status of craftsmen was second only to that of peasants, and was much higher than that of merchants who did not engage in production. At least in Qinghe Town, when Lu Biao, who sold salt, saw him, he had to respectfully call him a great craftsman. This is identity and status.

The blacksmith quickly walked into a relatively spacious wooden house in the center of Qinghe Town with a saw, but it didn't take long to come out and his face turned very ugly.

"Master, why are you so depressed?" Seeing the blacksmith come back with a dark face, an apprentice couldn't help asking.

The middle-aged blacksmith sighed and sat on the wooden stake and said, "Don't mention it, I took the copper saw to Lidian to watch. He actually said that I was randomly modifying the style of the equipment and saying that the saw I made did not comply with the craftsman's rules!"

"How could this happen?" The three apprentices didn't understand. One of them said, "This improved saw is so sharp, and saw wood is several times faster than an ordinary saw. You should be rewarded, right?"

The blacksmith touched his chin and said with a hesitation: "Lidian is old and pedantic. It seems that I must go directly to the county town of Zhixian. I heard that the new county magistrate came from the capital Xianyang. His knowledge and insights are not the same as those of the wild men in the mountain village here. So I decided, "You two should prepare horses quickly and bring your self-defense weapons to go with me!"

"Yes, master!" The two apprentices who were called quickly agreed.
Chapter completed!
