After changing the strategy, Shaokang set out with Ye Qing's price of raw materials such as tung seeds, brown horses, hemp fibers, silkworm cocoons, etc.

This time, Shaokang brought more wooden boats.

Before the beginning of spring, after squeezing out more tung oil, the wooden boats made by the wooden workshop can be put into use.

The fleet also brought a lot of bronze utensils.

First, a small part is used for exchange.

The price of bronze ware is not suitable for too low now, so Ye Qing set a relatively expensive price.

But it is not outrageously high either.

With the strength of the king and the witch king, you can still afford a lot of trades.

The types of bronze ware are temporarily just production tools such as axes, sickles, plows, saws, chisels, and pots.

Although the weapons such as arrows, spearheads, and daggers use very little material, Ye Qing has not exchanged for the time being.

The Dayu Kingdom has not yet discovered the secret of bronze smelting. What kind of tools are exchanged for, and it is only used as the purpose of this tool.

I haven't thought of it yet, nor do I know that these tools can be melted to cast weapons.

Not trading weapons will naturally prevent the ambitions of the Dayu Kingdom from expanding and creating bad ideas.

This time, Shaokang also took a task to build a trading base in the Dayu Kingdom, so a group of skilled carpenters accompanied him.

The task of these carpenters is to serve as technical instructors and organizers of construction sites.

Ordinary workers hire people from the Dayu Kingdom or slaves of the king and the witch king.

In such a big country of Dayu, there is naturally no shortage of ordinary labor.

There is a troublesome place to build a stronghold in the Dayu Kingdom, or in most countries around Leize, there is a troublesome place to build a stronghold, that is, to prevent floods.

Floods in this area are too frequent.

What are the ways to prevent floods from the ancestors of this area?

Built high terraces!

A platform that cannot be flooded!

Therefore, there are many terraces around Leize.

Any family, the huts are basically built on artificially built platforms.

There are vacant places to be built in the Dayu Kingdom.

However, the platform needs to be built by itself.

There are no built platforms in the city, and they are vacant and unused.

Building a platform will take more time and energy than building a thatched hut.

Some terraces that have lived for generations have been built to reach their current scale after several generations of continuous construction.

After all, digging soil with a bone-shaped wood plow is too inefficient.

But this problem is no longer a problem for the construction of trading bases.

Building a soil platform is already a very simple thing for the current Fengfeng family.

Shaokang carried picks, shovels and other tools with the ship were prepared for building a stronghold.

After the stronghold is built, these tools can also be used for transactions. I believe that the king and the witch king will be very happy to exchange them.

After Shaokang set out, Ye Qing arranged for the unemployed vagrants from the Dayu Kingdom who had been traded back to the copper mine and coal mine to mine.

Since we are preparing to trade bronze ware, it is necessary to increase the output of bronze.

Moreover, when promoting copper coins as circulating currency, the reserves of copper coins must be sufficient.

If there is not enough copper coins at that time, it will be a troublesome thing.

After re-arrangement and adjustment of the work, Ye Qing became busy with work that his tribe members were unable to do.

He began to make a coin minting machine.

Most of the ancient copper coins were cast.

Ye Qing does not intend to use this inefficient method.

He is ready to use stamping.

Even a bronze helmet can be stamped, and it is naturally possible to stamp copper coins.

But stamping copper coins is different from helmets.

The helmet is small, and even manual stamping does not take much time.

Copper coins are different.

The copper coins are too large.

Therefore, assembly line production lines must be built.

Then, there are multiple machines involved in the middle.

Only with the participation of these machines can the production line be produced efficiently and can minimize the reliance on manpower as much as possible.

In this era, the quality of workers is not as high as that of modern times.

They will be helpless with many simple questions.

Moreover, with such a production line, the credibility of copper coins can also be improved.

Every copper coin, size and shape, is an incredible thing for people of this era.

This can naturally increase the mystery of copper coins and then increase people's trust in copper coins.

Ye Qing sank into the casting of the coin production line.

Several diplomatic teams with Ye Qing's orders have set off with some goods.

Their mission is to visit countries around Reze, negotiate and establish trade relations, and inspect locations suitable for building strongholds.

They made outposts for future establishments.

In this era, land is not worth much.

The little land that establishes a stronghold is not a big deal for all countries.

However, close to the river and convenient for people to come to trade, we still need to choose carefully.

This group of envoys were still mainly the Dragon Armor Army.

In addition to the two hundred generals, Manniu and Lie, some of the better leaders, Tuncheng, were also selected as the heads of these envoys.

This also has the meaning of cultivating and exercising them in it.

There are six groups of envoys in total.

They set out in six different directions of Lei Ze.

One to the north, two to the east, and three to the south.

The north has the fewest tribes and countries, followed by the east and the south has the most.

The actual location of the Dayu Kingdom is not considered to be the south, but should be the southwest.

The Kingdom of Dayu is located in a huge basin surrounded by mountains. The north, west, and half of the south are all continuous mountains, and only the east is the endless swamp plain.

Although the population density and development level on this plain are not as good as that of the Dayu Kingdom, it is not as strong as that of the Dayu Kingdom.

In such a vast area, there are also a large population and tribes.

The messengers who went to this area also carried a secret mission, which was to find out where the salt produced in the Dayu Kingdom was produced.

Ye Qing was very curious about the ability of the Dayu Kingdom to supply all tribes in the entire Leize area to produce salt.

With the productivity of this era, it is almost impossible to produce so much salt.

The salt in the Dayu Kingdom is sea salt, which has been confirmed. So, should the Dayu Kingdom boil salt or dry salt?

If you cook salt, this scale will be huge.

That cannot be accomplished by the population of a few tribes.

Without thousands or tens of thousands of people cooking salt, the consumption of the entire Leize area would not be available.

If it is salt drying, it seems unlikely to be based on current technology.

First of all, the scientific design of this salt field, and the extremely grand salt field development compared to this era, were difficult for the Dayu Kingdom to complete.

The development of salt fields is different from the building of a platform by piled up soil.

Therefore, Ye Qing felt that there should be a secret of the source of salt in the Dayu country.

For this purpose, the farthest distance of all messengers is based on reaching the seaside.

They all need to look for similar places on the beach, according to the sand table made by Ye Qing.

These places are suitable for opening salt fields to dry salt.

Ye Qing is preparing to make his own salt.
