Luo Yong is indeed busy. He and his disciples are trying to mass-produce the compass in recent days.

The principle of the compass is not complicated. When I was studying, the school also taught hand-made simple compass. It only takes an embroidery needle and a magnet, and a little paper, cotton thread, etc. to make various compass.

But if you want to make it more delicate and durable, you have to spend more time on that pointer. The main thing is the forging and magnetization of the pointer.

Magnet has existed since ancient times. Before the Han Dynasty, people called it "Ci Shi".

Iron ore can often be found where magnets are found. The ancients believed that stones were the mother of iron. There are also two types of stones: kind and unkind. The charity stone can attract children to gather around it, but unkind stones cannot.

At this time, people in the Tang Dynasty called magnets magnets. Some of them also used medicines. However, they were not very popular in ordinary small pharmacies.

Since Luo Yong came to Changle County, he heard that most of the Hu merchants were walking along the footsteps of their predecessors at this time. Only a few people knew how to identify the direction, and there were very few caravans with valuable objects like Sinan.

It was from then on that time that he asked someone to look for magnets. This autumn, Hu Shang brought him a lot from the south.

Luo Yong bought these magnets and tinkered with Qiao Junlin to make a compass. It’s a pity that neither of them is professionals, and the finished products they made are relatively simple, and it is not certain whether they can be used for a long time.

This time Hengzhi came over. After hearing Luo Yong talk about the compass, he pierced in.

There were several other disciples who helped him, and Luo Yong often went over to give advice. Seeing them working, he sometimes had to get started.

The tea price reduction promotion outside is in full swing, and the master and apprentice are behind the county government, doing craftsmanship work all day long.

In addition to the compass, Luo Yong also planned to draw some maps. Even if a person without geography is given a compass in the world, he had no idea where he should go.

During the Sui Dynasty, Pei Ju once painted the "Magic Records of the Western Regions" for Emperor Yang of Sui, which included several business routes from the Hu merchants, as well as the mountains, rivers, customs and customs of the forty-four countries in the Western Regions. I don't know where this book is now, but Luo Yong would not be able to see it in a short period of time.

In addition to compass and maps, language is also very important. Most of the Hu people who came to the Tang Dynasty to do business are proficient in Chinese, but the Han people think that few people can speak foreign languages ​​and can't speak foreign languages. Once they go out, they will be blind.

That’s right, it’s just going out. In addition to passively accepting the information brought by the Hu merchants, Luo Yong hopes that some people in the Tang Dynasty can go out and go to the Guangpeng Western Regions world to find profits and broaden their horizons.

This is also the first thing Luo Yong said to him after Tang Jian arrived this time.

Although tea trading is important, it is even more important to change the current passive acceptance of the Hu merchants from the Tang and Western Regions in the trade process.

On this day, after two caravans passed by in front, another caravan slowly headed towards the desert.

Many of the Hu merchants in this caravan have settled in Dunhuang, and they are always very reluctant to part, so they delayed a little. If they walk tightly at this time, they will be able to arrive at the first oasis on the business road that goes west before sunset tonight where merchants can rest.

The caravan was walking in front and their family followed behind. This was a delivery to the Thousand Buddha Cave.

Between those Hu merchants and families, there was an old man who was quite old and was so thin that he was left with only a bone. He was leaning on a wooden stick in his hand, moving step by step, following the team without falling behind at all.

In this caravan, behind the Hu merchants who were leading camels, there were also a group of porters carrying goods, among which his son was.

The old man followed the young man who cared for the goods all the way, but never looked back at him and just walked.

This summer, a wealthy family in the city was going to dig a cave in the Thousand Buddha Cave to worship Bodhisattvas. He found a job of carrying a stone here, but he was not even hit by a falling stone on the cliff and was unconscious for a moment.

When he woke up, his two children had been sold by his father. His ten-year-old daughter was taken by a middle-aged Hu Shang. His seven-year-old son also became a slave to the family. Some time ago, he was beaten to death by his master because of some things. The young man learned about this and went to the door to fight with others. However, the other party told him that as long as he could pay two cents of money, the boy would ask him to take him home.

Now, the caravan has promised him two stagnant money. As long as he helps these people carry half a load of goods to the Bangduoshiluo Kingdom this fall, and then from the Bangduoshiluo Kingdom to Dunhuang next year, he will get two stagnant money.

According to the rules, the Tang people were not allowed to go out of seclusion privately, but this caravan has been operating in Dunhuang for many years and can help them get documents for seclusion. After all, the price of porters is much lower than that of camels and can understand the arrangements of the caravan. If something happens, they are also a man who can help, and they are stronger than livestock.

Although the Hu merchants in this caravan are not very kind and kind, considering that they will use the porters to carry goods back in the spring next year, they will not harm their lives for no reason.
