Chapter 450 Timing Tool

Li Yan found Wen Ge and told Wen Ge that he wanted to make a stable timing tool. Wen Ge also expressed his full support.

Li Yan took paper, pen and ink, and drew the design and raw materials.

But this timing tool is something from his previous world, so it is quite difficult to do it.

Fortunately, this thing is not difficult to make, as long as you find the raw materials.

"Your Majesty, do you mean that you need to find a kind of fragrant wood?" Wen Ge asked seriously after reading Li Yan's drawings.

"That's right, wood with fragrance. However, many trees have fragrance. If you want to find them all, let me have a look." Li Yan said.

"Scented wood. I have to go to the medicinal materials department. Our Ministry of Industry is not very clear about the scented wood. If you say hard wood or soft wood, I can help you find it. This scented wood , we don’t know.” Wen Ge shook his head.

"Well, okay then, let's go to the medicinal materials department." Li Yan said with some regret.

But Wen Ge was right, the Ministry of Industry would not pay attention to fragrant wood at all, or the Ministry of Industry would only be able to come into contact with it when the spice industry in the Han Empire developed.

Li Yan stood up and turned to leave the office building of the Ministry of Industry, and Wen Ge followed.

However, Wen Ge's legs were disabled and he walked very slowly, so he raised a giant ape, which carried him and followed Li Yan away.

The medicinal materials department is on one side of the industrial park. This is the place where medicines are produced. There are several houses with yards, each with different functions.

In the past, the person in charge of medicine in the Taka tribe was Bai Wu, that is, Li Yan's mother, but his mother is now the head of the medical department.

The Han Empire ruled thousands of miles of territory, with many counties and towns under it, and medical care and education were important departments of the Han Empire.

Having just recovered 25 tribes in the northwest, Bai Wu will take a medical team to these 25 tribes to sort out the medical care of those people and prepare for the construction of hospitals. Every time a place is conquered, medical care and education must keep up!
Now, the person in charge of the medicinal materials department is the deputy medical minister named Jiang Tu. She is a woman, but she has done a very good job.

After Li Yan and Wen Ge came here, they found Jiang Tu and told them about the idea of ​​making the timing tool.

Jiang Tu was also very cooperative, and found all the fragrant wood and even grass leaves from the medicinal materials department, and handed them to Li Yan to smell them.

A large table of wood, leaves and grass roots is dazzling.

Li Yan picked up the wood one by one and smelled it all the time, some wood was very offensive, some wood had a light fragrance, but none of them were what he was looking for.

"Haha, this is this kind of wood!"

"By the way, where did you find this kind of wood?"

After smelling it for more than an hour, when Li Yan smelled a piece of wood, his face immediately showed joy.

"Return to Your Majesty, this is a specialty of Wuxian County. There is this kind of wood on their islands. It is a medicinal material for treating headaches." Jiang Tu replied repeatedly.

"Okay!" Li Yanxi said, "This is sandalwood, how much of this kind of wood do you have?"

"Your Majesty, there are still a few in the warehouse." Jiang Tu said.

"Well, send it to the industrial park for me." Li Yan said after taking the few pieces of sandalwood.

"Okay." Jiang Tu nodded quickly.

Li Yan took these pieces of sandalwood, and went back to the industrial park with Wen Ge, and they came to the factory for grinding stone tools.

Stone tools such as stone mortars and stone mills are produced here. When I came here, I saw that the workers here were already selling land and working.

Some people are carving stone tools with chisels and hammers, and some are grinding stone sticks, very busy.

In addition to the workers, there are several long-haired savages here, that is, Homo erectus. Li Yan had ordered many savages to be brought back.

The brains of these savages are not as smart as humans, but their IQ is much stronger than that of giant apes and orangutans. They have the IQ of about ten years old. The post of labor increases productivity for the Han Empire.

The director of the stone tool factory received Li Yan's order to grind the sandalwood into powder. This is very simple, but it takes time, so Li Yan handed over the grinding work to the stone tool factory.

Then, he came to several newly built public toilets in the imperial city.

These public toilets were specially made by Li Yan for the production of gunpowder a few months ago. Later, Li Yan discovered that ignition powder plus charcoal powder can perfectly replace gunpowder.

As a result, the gunpowder formula of the sulfur, charcoal, and saltpeter world he designed was left behind and no longer studied, because the gunpowder in this world is better, directly adding charcoal to ignition powder.

However, Li Yan needs to start this plan again now, but the public toilet he built before can be used just now.

In fact, this public toilet has been out of use for a long time, but the substances generated in it have not fallen.

There is only a place to pee in this public toilet, which is a ditch, and then a brick wall is built.

When Li Yan came inside, he saw many white crystals attached to the walls. They were crystals of nitrate, which was one of the necessary materials for making gunpowder, because the urine of animals and people contains nitrate, and when the nitrate evaporates, it will adhere to the walls and carry it. Physically, it is an easy-to-find substance.

Li Yan ordered people to scrape the nitrate from the public toilets. In fact, if the nitrate is used to make gunpowder, it needs to be filtered again, but Li Yan does not make gunpowder, but uses the nitrate as a combustion aid. Wood flour is mixed, so no special treatment is required.

After scraping the nitrate, Li Yan returned to the millstone factory. At this time, some sandalwood powder had been ground in the stone tool factory.

The combustible nitrate and the raw material sandalwood powder seem to be worse than the same adhesive.

So, Li Yan went to the ink factory in the industrial park. The ink factory has gelatin, which is collagen boiled directly from animal skins. Collagen is mixed with oily smoke to make ink. Collagen is an adhesive. Li Yan directly I asked for some and went back to the stone tool factory.

Next, Li Yan personally mixed sandalwood powder, gelatin, and nitrate powder with water, and kneaded the sandalwood powder into a sticky mud.

After kneading it into mud, he found a small bamboo tube, which was only about the diameter of a finger, but [-] centimeters long. Besides this piece of bamboo tube, he also peeled off a dry bamboo stick.

That's right, the timekeeping tool that Li Yan wants to make is sandalwood. Ancient people didn't have watches, and they used incense as a unit of timekeeping, such as the time of a stick of incense.

And what Li Yan wants to make is a large sandalwood, with a bamboo tube, which can make the sandalwood the same thickness and length, so the sandalwood worth it is all standard.

As long as you burn sandalwood, calculate the length of day and night, and when you enter the ark in the island of distortion, you can directly light the sandalwood to calculate the time.

At that time, you will be able to know exactly whether it is day or night in the outside world according to how many sticks of sandalwood you burn!

Mix bamboo sticks with sandalwood powder, seal it in a small bamboo tube to shape it, and then take it out to dry, and a piece of sandalwood is ready.
