The three of them got into the car and passed by Meiyuan. Boss Xue went down and said.

He also helped Zhou Heng bring some clothes to change. The doctor has a vigilance and can tolerate everything else, but the smell of sweat and dirt made him unbearable. Boss Xue knows a little more now.

Then he went all the way and headed towards Jiyang County.

Although the two counties are close, it is difficult to walk around the donkey carts along the way through two mountains. It took nearly two hours to arrive in Jiyang County.

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

The store is very small and it is easy to miss it if you don’t look closely. Three people entered, Zhou Yian and his friend explained their purpose, and the man quickly went to invite the boss.

Zhou Heng kept looking at it and found that there were many glass objects in the shop, including bottles half a person tall, and small ones as big as thumbs.

Most of them are of great color, vases, utensils, screens, jewelry, craftsmanship and design.

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

While watching, Zhou Yian brought a tall man and walked up to Zhou Heng to hold his fists and salute him.

"Hello, Mr. Zhou."

Zhou Heng smiled and said, "Boss Zhou, don't be polite. We are all surnamed Zhou, so we are destined to be. I want you to see some items when I visit today. Can you do some things?"

"Okay, please come from Mr. Zhou."

Zhou Heng held the drawings and followed Zhou Zhimin to the backyard. There was a workshop and a tea room. You could tell at a glance that this person was a person who knew how to enjoy it. The two sat down, and Zhou Yian stood behind Zhou Heng with his hands hanging down.

Zhou Heng took out a drawing of a syringe and handed it to Zhou Zhimin. If this can be done, everything else will be easy. As for the glass bottle or the alcohol stove, it is very simple, just need to make some accessories.

"Boss Zhou, the item I need needs to be used in combination. This item is called a syringe, which is divided into two parts, one is a syringe and the other is a plunger. There are two key points in the production of this item. One is that the plunger needs to be tightly fitted and can be pushed into the syringe, which must not only be leaky, but also be able to push. The second is that the position of the needle mouth must 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, gestured for the size, but did not answer Zhou Heng that he could not do it, but just thought for a while and asked.

"Mr. Zhou, can you give me a brief explanation? Should I only make one item, or do I need a large amount?"

When Zhou Yian heard this, he quickly stopped Zhou Zhimin.

"Uncle cousin, my uncle is in a hurry to save someone"

Zhou Heng grabbed Zhou Yian's arm and smiled at Zhou Zhimin.

"Boss Zhou is quick and easy to speak. I like to do business so directly. Let's say that, as long as the price is right and the size meets the standard, I will need it for a long time. I will order fifty of them in the first batch, of course it is just this one item."

Zhou Zhimin was stunned, which means there was something else.

"If Mr. Zhou has time, can I make one, please see if you can tell if it is appropriate."

Zhou Heng smiled, "That's what he meant."

Boss Zhou raised his head and laughed, "It's so enjoyable to talk about business with Mr. Zhou. The price is easy to say. If the quantity you want is large, you can make molds."

Several people got up, went directly to the workshop, spread out the drawings, and Boss Zhou took off his outer robe, tied his apron, and wore heavy gloves.

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

He moved very quickly and kept blowing and rotating. After a few efforts, the shape of the syringe appeared. He cut off the excess, measured the position of the needle mouth, adjusted the shape, and then placed it aside to cool down.

Then I changed a long hook and started making the plunger. The size of this was a bit inaccurate. After trying it a few times, I finally had two more satisfied with Zhou Zhimin.

Waiting for the two parts to cool down, I tried to assemble them. Once I installed them, I found that one was stuffed in directly, but there was a gap, and the other was a little thicker. After stuffing it in, it could not be moved. Zhou Zhimin's head was sweating.

Zhou Heng recalled that there were traces of frosted marks on the old-fashioned glass syringe plunger. It seemed that it was not only for adjusting the size, but also for increasing friction.

"Boss Zhou, if you polish this, it will be smoother."

Zhou Zhimin found a wooden board with fine particles on it. It seemed that this was his grinding tool. He rotated and grinded the plunger around. There was a slightly formed position and polished it more carefully several times before installing it again, let alone succeed this time.

Zhou Heng took it and tried to push it. The resistance was not very smooth.

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

Zhou Yian quickly went to the tea room and took a cup of water. Zhou Heng used a syringe to extract some water and turned the syringe to observe. There was no leakage between the plunger and the needle tube. He pushed it hard and flew out a trace of water at the point of the needle's mouth and fell into the yard.

"The quality is very good, just follow this standard. Each plunger is polished to make it smoother and the thrust is not too big or small."

Zhou Yian was thinking about something beside him, staring at the syringe and his eyes widened.

"Uncle Master, we can also use this thing for coroner post-mortem. Every time we check the internal organs, the food and blood in the stomach will be mixed together. If the blood in the internal organs is cleaned up, it will be easier to observe."

Zhou Heng looked at him, but he didn't expect that this kid had good development ability. He knew that observing the microscope and having such details were still available. He was a man of craftsmanship.

"It's not just that. If a hollow needle is installed in front of you, you can get blood in the heart of the deceased without an autopsy. If it is in a state of flow, some drugs can be used to determine whether the deceased died of poisoning. In this way, many people who do not agree to the autopsy can determine the cause of death."

When Zhou Yian heard this, he felt energetic, but he held the syringe and sat and shook his right.

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

“It can be made in different sizes, the bigger the easier it is to make.”

Zhou Zhimin nodded, "Yes, it looks difficult, let alone it be easy. If this is qualified, then you can do it in 50 pieces without a mold."

Zhou Heng turned the drawing to the next page and said, "Since that's the case, let's look at something else. This bottle does not need to be gorgeous. It only needs to be a small belly. It needs a plug at the mouth. The size should not be too strict. Just cover it on it and leave a thick hole in the center."

With the research of the three people, they tried again and again over three days, including alcohol lamps, drip observation tubes, infusion bottles, grinding bottles with lids, and a plate-sized magnifying glass.

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

After carefully wrapping all the glassware, the three of them drove back to Qingping County in a donkey cart. Boss Xue was surprisingly quiet along the way, and Shibuchang sighed, but Zhou Heng didn't ask much when he saw it.

In Jiyang County, Boss Xue went out for two days and was like this when he came back. It was related to the previous sale of glutinous rice lotus roots in Jiyang.

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

And these people are very familiar with Boss Xue, which at least makes him very embarrassed. For Zhou Heng, whether there is sales in this county is not much impact, but for individuals who can share the money, the impact is indeed quite large.

As soon as the donkey cart entered Qingping County, Zhou Heng asked Zhou Yian to go back to the yamen first. He and Boss Xue went directly to the Yao Ji Blacksmith Shop next to the tavern where the last accident happened.

As soon as the carriage stopped, Zhou Heng got out of the carriage with Boss Xue. The donkey carriage that had been sore all over, and he stomped his feet and stretched his arms and legs.

The big man holding a sledgehammer stopped his hand and stared at Zhou Heng.

Zhou Heng walked forward and clasped his fists at the big man.

"I've disturbed my brother's business, I want to ask you something."

The big man clanged and threw the hammer on the iron rack beside him, wiped his hands and looked at Zhou Heng with a vigilant look.
