Time flies to noon the next day.

The sky was gloomy and it seemed to be raining.

Chen Xu, Niu Dashi and two young men followed Uncle Ma to send four villagers who were going to participate in the road construction to Qinghe Town.

"You four must be together and not separate when you go, take care of each other, keep the money in close proximity, and keep the food in mind. Remember not to argue with others and hate. Don't worry about the crops at home. I will arrange for someone to help you harvest, and I will also reduce taxes when serving. This year your family will pay a lot of less food..."

As the village chief, Uncle Ma sent the four people to the meeting place in the town and then asked the pavilion chief to report, and then repeatedly reminded him.

Chen Xu took out several bamboo tubes Niu Dashi carried in the basket and distributed them to four people.

"Brother Dazhuang, this bamboo tube contains human pills. Remember, if the weather is too hot and you feel chest tightness and breathless, you can hold one or two pills in your mouth. If it is so severe that you have headaches, dizziness and weakness, you can eat three to five pills at a time... This bamboo tube contains licorice tablets. If you eat badly, you can soak in water and drink it. If you have a dry stomach, you can also eat it, but you can't eat too much. If you are injured and bleeding, use the medicine powder in this bamboo tube to stop the bleeding and bandage it. Take this orally, take this if you have a cold..."

Chen Xu opened each bamboo tube next to each other and explained it carefully to the four people.

"Xiaoxu, you really worry. We will definitely return the money to you when we come back!" Tian Dazhuang and Ma Erdan were all grateful to Chen Xu.

"What are you grateful for? They are all from the same village. Take good care of your health. By the way, don't spread these medicines, and it's best not to let others discover them!" Chen Xu gave a special reminder at the end.

"Don't worry, Xiaoxu, we won't spread it!" The four of them nodded with serious expressions.

It has become a consensus among villagers that Chen Xu can treat his illness, so he respects him very much. People in the village think that what he says is very important. And they have also heard that Chen Xu risked the mountain in order to get these medicines. He worked for two days and two nights. This selfless help touched them.

With these medicines, the possibility of them returning alive has increased a lot.

The four men wearing ragged clothes carrying large vine baskets had a red eye circle. After turning around and meeting with the civilians from nearby villages, they soon walked towards the county town led by a few horse-riding soldiers.

It is almost fifty miles from Qinghe Town to Zhixian County. It takes at least four hours to walk. It is estimated that it will be almost evening when you arrive at the county town.

"I hope God will not rain!" Chen Xu sighed at the dark clouds, and then went to the blacksmith shop with Niu Dashi again.

But what he didn't expect was that the short and fat middle-aged blacksmith was not there, and only a tall and thin apprentice in his twenties was left.

The apprentice looked very unnatural when she saw Chen Xu, and her eyes kept dodging the two of them.

"Where is the master craftsman? Call him here quickly. We will buy some things this time and create a few customized tools!"

"My master was summoned by the county magistrate to build logging...the road construction tools are there! I am the only one left here. You can tell me what you need!" The apprentice said stutteringly.

Although Chen Xu thought the apprentice's performance was a bit strange, he didn't care. Now that civil servants are being recruited to build roads, it is normal for craftsmen from various towns to be gathered by the town to create road construction tools.

"It doesn't matter if your master is not here. Today, you can help me build two awls, two chisels and a set of bamboo knives. The specifications and styles should be like this..."

Chen Xu picked up a piece of charcoal from the ground, drew awls, chisels and bamboo knives on a bluestone slab next to him, and said carefully about the size and length.

"These are all small objects. I can build them all by myself soon. Please wait!" The apprentice quickly opened the stove and put several pieces of copper piers of different thicknesses and lengths into the stove. Then he blew them with the blowing skin bag for a while. The charcoal fire in the stove quickly burned, and the copper piers began to turn red.

As the saying goes, the apprentice is guilty. This apprentice never dared to look at Chen Xu in front of him. After the blowing of the wind and then the copper piers turned red, he clamped it out with a pliers and started to pound it with a small hammer.

A few days ago, he knew that the master and two senior brothers were highly praised by the county magistrate for the bronze saw, and they also went to the county town together, and were praised by the county magistrate. The master had been promoted to a master craftsman by the county magistrate, and coordinated the management of more than 200 blacksmiths in the county recruited this time, guiding them to make the modified bronze hand saw. Not only was the status incomparable, but he also heard that the county magistrate would also inform the craftsman in Xianyang, the capital, to ask for merit.

But he knew that the improved copper saw was not invented by the master, but the young man with a torn and thin clothes in front of him.

Therefore, when Chen Xu and Niu Dashi came in, he was always worried and almost let it go.

Once the improvement of the bronze saw is not invented by Gushan, it will be spread, the more rewards the Gushan will receive, the more miserable the consequences will be.

If the matter is revealed to Xianyang and the First Emperor, the crime of deceiving the king can crush everyone, including himself, into pieces.

During the tense and restless beating of the apprentice, it took about an hour to make two copper cones, two chisels and a few tools for breaking bamboo and washing.

These are all small things, and they use very little copper material, so they only cost seventy or eight things. Chen Xu paid the money very easily. Before leaving, he remembered that the saw at home was so frustrating to use, so he asked if there was a new saw this time.

The apprentice was so nervous that he almost turned his back. He nodded hesitantly and said, "I took out an extended bronze hand saw from a wooden box, and said with a red face: "Little Langjun, this is the one I made according to the style you last time. Do you think it's OK?"

Chen Xu took it and found that not only was it much longer, the density and size of the serrated teeth were more suitable, but the serrated teeth were also staggered on both sides, basically meeting his own requirements.

"It's not bad, it's not bad, how much is it?" Chen Xu nodded happily.

"One...one hundred coins!" The apprentice stretched out a finger.

"Okay!" Chen Xu counted another hundred dollars without any hesitation, then packed up his things and threw them into the basket and left the blacksmith shop with Niu Dashi and the others.

"Hu~" The young apprentice breathed a sigh of relief, and sat on the stone with sweat wiping her head, her heart was so pounding that she couldn't stop.

Looking at Chen Xu's back, he always felt that the bronze hand saw was not as simple as the master said.

This boy is very not simple, and the few items he created today are different from the commonly used tools.

One of the awls actually had a small barb. He had never seen two chisels before. One of them was semicircular and I don’t know what it was used for, and I don’t know what it was for, because at this time, although people had already started to use bamboo in their lives, it was limited to building houses and making some simple daily necessities such as bowls, chopsticks, cups and buckets. I haven’t started to use bamboo to make things common in later generations such as mesh sieves, dustpans, mats, curtains, mosquito nets, etc.

Should we tell the master these newly emerging tools?
