The three of them got into the car and passed through the plum garden, and Boss Xue went down to say something.

I also helped Zhou Heng bring some change of clothes, the doctor has a habit of cleanliness, and he can tolerate everything else, but the smell of sweat and dirt makes him unbearable, and Boss Xue knows a little bit now.

Then he didn't stop all the way and headed towards Jiyang County.

Although the two counties are closer, but separated by two mountains, the donkey cart is a little difficult to detour all the way, and it is nearly two hours before arriving in Jiyang County.

Under the guidance of Zhou Yi'an, the three of them quickly found this Liuli Pavilion.

The store is very small, and it is easy to miss it if you don't look carefully, the three of them entered, Zhou Yi'an and the guy explained their intentions, and the man hurried to ask the boss.

Zhou Heng kept looking, there were a lot of objects made of glass in this shop, the big ones were half-human tall bottles, and the small ones were thumb-sized ornaments.

Most of them are colored, vases, utensils, screens, jewelry, craftsmanship and design are very remarkable.

You must know that in later generations, this colored glass is not easy to make, after all, it must be mixed with different substances in order to control the color.

was watching, Zhou Yi'an brought a tall man and walked up to Zhou Heng and hugged his fists.

"Zhou Gongzi is good."

Zhou Heng said with a smile: "Boss Zhou, you're welcome, we are all surnamed Zhou, we are fate, I want you to see if you can do some things?" ”

"Okay, then Childe will please."

Zhou Heng followed Zhou Zhimin to the backyard with the drawings, there is a workshop and a tea room, at a glance, he knew that this person knew how to enjoy, the two sat down, and Zhou Yi'an stood behind Zhou Heng with his hands down.

Zhou Heng turned out a drawing of a syringe and handed it to Zhou Zhimin, if this can be done, everything else is easy to say, as for the glass bottle or the alcohol stove, it is very simple, just need to get some accessories.

"Boss Zhou, this item I need needs to be used in combination, this item is called a syringe, and it is divided into two parts, one is a needle and the other is a plunger. There are two key points in the production of this material, one is that the plunger needs to be tightly fitted to be able to push into the needle tube, not only to not leak, but also to be able to push it. The second is that the position of this needle tip should be standard in size, and the metal needle in front of it cannot be installed if there is a slight deviation. ”

Zhou Zhimin looked carefully, found a metal caliper, compared the size, and did not answer that Zhou Heng couldn't do this, but just thought about it a little and asked.

"Zhou Gongzi, can you give me a bottom, is this object only one piece, or does it require a large amount?"

When Zhou Yi'an heard this, he hurriedly stopped Zhou Zhimin.

"Uncle Cousin, my uncle is in a hurry to save people......"

Zhou Heng grabbed Zhou Yi'an's arm and smiled at Zhou Zhimin.

"Boss Zhou is fast-talking, I like to do business so directly, let's put it this way, as long as the price is right and the size is up to standard, I will demand it for a long time, and I will order fifty in the first batch, of course, it is just this one single item."

Zhou Zhimin was stunned, which means that there are others.

"If Zhou Gongzi has time, I will make one and see if it is possible, so that you can know whether it is suitable."

Zhou Heng smiled, "That's what I mean." ”

Boss Zhou raised his head and laughed, "It's really fun to talk about business with Zhou Gongzi, the price is easy to say, if you want a large quantity, you can make molds." ”

A few people got up, went directly to the workshop, spread out the drawings, and Boss Zhou took off his robe, put on an apron, and wore heavy gloves.

Use an iron hook to open the mouth of a furnace, hook up a piece of transparent glass material, stuff it into the small furnace and twist it continuously, and in a moment the glass begins to soften.

He moved very fast and kept blowing and rotating, and after a few strokes, the shape of the needle appeared, cutting off the excess part, measuring the position of the needle mouth, and adjusting the form, before putting it aside to cool.

Then I changed to a long hook and began to make plungers, the size of this one began to be a little inaccurate, and after trying a few times, there were finally two Zhou Zhimin who were more satisfied.

Waiting for the two parts to cool down, trying to assemble them, as soon as they were installed, they found that one was directly stuffed in, but there was a gap, and the other was a little thicker, and it was impossible to move one-fifth of the way in, and Zhou Zhimin's head was sweating.

Zhou Heng recalled that there were traces of frosting on the plungers of the old-fashioned glass syringes, which seemed to be not only to adjust the size, but also to increase friction.

"Boss Zhou, how about polishing this, it will be smoother."

Zhou Zhimin found a wooden board wrapped in leather, with fine particles on it, it seemed that this was his polishing tool, and he rotated and grinded the plunger around, and there was a slightly made position to polish it more carefully a few times, and then it was installed again, not to mention that this time it was successful.

Zhou Heng took it and tried to push it, but the resistance was not big and smooth.

"Yi'an, get a glass of water!"

Zhou Yi'an hurriedly went to the tea room and took a glass of water, Zhou Heng used a syringe to draw some water, turned the syringe upside down to observe, there was no leakage between the plunger and the needle, and a water trail flew out at the position of the needle mouth and fell in the courtyard.

"The quality is very good, just according to this standard, each plunger is polished once, so that it is smoother, and the thrust is not too big or small."

Zhou Yi'an was thoughtful beside him, staring at the syringe, and his eyes widened instantly.

"Uncle Shi, we can also use this thing for an autopsy, every time we probe the internal organs, the food and blood stains in the stomach will be mixed together, if the blood stains in the internal organs are cleaned up, it will be easier to observe."

Zhou Heng glanced at him, but he didn't expect that this kid's own development ability was not bad, he knew that observing the microscopic and having such details was a manufacturable material.

"More than that, if a hollow needle is installed in the front, the blood in the heart of the deceased can be obtained without an autopsy, and if it is in a fluid state, some drugs can be used to determine whether the deceased died of poisoning, so that many people who do not agree with the autopsy can determine the cause of death."

Zhou Yi'an was refreshed when he heard it, but he held the syringe and shook it to the right.

"It's a little smaller, it's better if it's bigger!"

"You can make different sizes, and the bigger the better."

Zhou Zhimin nodded, "Yes, it's very difficult to look at, not to mention it's easy, if this is qualified, then it can be done in fifty or five days without a mold." ”

Zhou Heng flipped the drawing to the next page and said: "Since this is the case, let's look at something else, this bottle doesn't need to be gorgeous, as long as the belly is big and short, the position of the mouth needs to be a stopper, the size does not need to be too strict, it can be covered on it, and a thick hole is left in the center." ”

With the research of the three of them, three days, they tried again and again, and the alcohol lamp, the drip observation tube, the infusion bottle, the grinding bottle with the lid, and a plate-sized magnifying glass were all made.

This magnifying glass also made a bracket, which can be adjusted to support it on the bed, and it can be held without a handle, so that the stability is better, and all the things cost less than fifteen taels in total, this price, Zhou Heng is still satisfied.

Wrapping all the glassware carefully, the three of them took a donkey cart back to Qingping County, along the way, Boss Xue was surprisingly quiet, and sighed from time to time, Zhou Heng didn't ask much when he saw it.

In the past few days in Jiyang County, Boss Xue went out for two days, and when he came back, he was like this, and he contacted the previous sale of glutinous rice lotus root in Jiyang.

You don't have to think about it to know what you've discovered.

And these people Xue Boss is very familiar, at least it makes him very embarrassed, for Zhou Heng, whether there is sales in this county has little impact, but for the individuals they can share, the impact is indeed relatively large.

As soon as the donkey cart entered Qingping County, Zhou Heng asked Zhou Yi'an to go back to the yamen first, and he and Boss Xue went directly to the Yao Ji blacksmith shop next to the wine shop where the accident happened last time.

As soon as the carriage stopped, Zhou Heng followed Boss Xue out of the car, and after sitting in the donkey cart for two hours, he was sore all over, stamping his feet and stretching his arms and legs.

The big man with a sledgehammer to strike iron stopped what he was doing and stared at Zhou Heng.

Zhou Heng stepped forward and clenched his fist at the big man.

"I'm disturbing my eldest brother's business, I want to ask you something."

The big man clanged, threw the hammer on the iron frame on the side, wiped his hands and looked at Zhou Heng with a vigilant face.

"I know you, the last time you reported the incident in the wine shop."
