On Sado Island, Japan, a group of labor prisoners wearing uniform felt overalls and short hair are wielding hammers and hammers to break stones in a stone quarry by the sea. Large chunks of stone have been blasted apart by the powder, but they still need to be broken by manpower before they can be used to pave the road.

As for convenient equipment such as hydraulic forging hammers/breakers, I'm sorry, everything is simple here on Sado Island, and such advanced equipment has not been installed.

And these labor prisoners in labor are also serious prisoners of the Han region, or stubborn prisoners of war in the Khitan, Jurchen, Dangxiang and other ethnic groups, and Zhao Gou is not soft at all when he uses them.

This Sado Island is open up to wasteland, but it needs manpower very much, so if you don't need these people, do you still need the Ministry of Industry to spend money to hire people?

As for why these people all have short hair, it is that they have already been shaved at the beginning of their sentences. If you don't shave, you can't do it, you have long hair to open up the wasteland, lice, dirt, and the hygiene problem can't be solved at all, only bald is clean.

As for whether the prisoners are willing to shave their hair, they have to bow their heads under the roof, which is beyond their control.

What's more, three meals a day after shaving: two dry and one thin, and you can mix some dried meat and fish every day to eat. Those who don't shave their hair can only do one thing and two meals to survive, and the work is even harder, not to mention that the Khitan, Jurchen and Dangxiang ethnic groups have a tradition of baldness (baldness does not mean baldness), even the Han people no one can bear it.

No matter how big the rules are, they can't be bigger than their own lives, and they can't be worth their belly.

And they were all thrown into the sea, except for working hard to escape as soon as possible, there was no one watching them over there, and no one could escape, right?

Where can they flee?

Since Zhao Song negotiated cooperation with Japan, the few Japanese on the island have moved inland. Now this place is a prospecting team, except for the garrison and the prisoners who have been assigned to the labor camp.

Everything on Sado Island is being prepared for the gold and silver mining in the near future, and it is a transit station for the sea soldiers and horses led by Liu Ziyu to make supplies.

That's why the prisoners are so hard, because their workload is extremely huge, and they have to build ports and open up transportation. In the future, I will have to work in the mines.

It is also said that at the moment, it is just rubbing stones on the beach against the cold wind, which is all easy work.

Although Sado Island does not have a natural harbor, as an island, it is not a piece of cake to build a harbor under today's conditions. Aren't you going to build the Sailor Base here?

In addition to these 500 or 600 regular soldiers, there are now exploration teams of more than 1,000 people, divided into multiple teams, and under the leadership of experienced masters, they have been working hard in the mountains of Sado Island for more than half a year. The results are remarkable!

Then there were the more than 2,000 prisoners.

The total population is not less than 4,000, which is not inferior to the original population of Sado Island.

The Japanese government said it sounded very good, but in fact it had deployed additional troops and horses in the Echigo and Central areas on the other side. However, compared with the caution and prudence of the Japanese government, the merchants of Echigo and Echichu were happy. Because of its backing to Japan, many of the resources needed for the reclamation of Sado Island, whether it is food or daily tools, are purchased directly from Japan.

This is a population of 4,000, and their material needs, even if the treatment of many prisoners in labor camp cannot be compared with that of soldiers and exploration teams, but the total amount cannot be underestimated.

Because the prisoners of labor camp also work hard, as long as they are obedient and obedient, and do two jobs a day, they will also make people have enough to eat.

In this way, the neighboring Japanese businessmen have reaped a lot of benefits.

Because when Zhao Song purchased materials from Japan, he was extremely generous. Not to mention the price of goods in Japan, just talk about the convenience of nearby purchases and the promotion of the development of Sado Island, then the Zhao Song government will not care about such a small amount of money at all.

Today's Sado Island is a hot labor. Regardless of whether it is voluntary or not, they are all working intensively.

That is, the officers and men stationed on the island are busy one by one, and their feet do not touch the ground.

Because this rubble and transportation errand is not only done by the prisoners of labor camp, but also by the soldiers.

In addition to the necessary guarding and surveillance work, half of the officers and soldiers were always busy on the stone field every day. This is the fundamental reason why Sado Island has been able to build a beautiful stone base in such a short period of time.

Diligent. Not only the prisoners were oppressed and had to work hard, but even the soldiers and exploration team members on the island were diligent one by one.

There's no added bonus to this, it's just a subtle habit that becomes natural.

When Zhao Song first landed on Sado Island, although there were several Japanese villages and towns here, the wooden houses obviously did not meet Song Jun's pursuit, and it was not safe to use them as prison cells.

What's more, the order they received was to build a stone city, and the interests of Sado Island were unknown to the Song officers and soldiers, exploration team members, and labor prisoners, but Zhao Gou of Bianliang City knew it. Who can guarantee that the Japanese, after gaining insight into the interests of Sado Island, will not send troops to fight?

Therefore, based on the future, building a strong fortress is what must be done.

The people of Sado Island, no matter what their status, have been putting into construction with full horsepower since the first day they came to the island.

Now don't look at Sado Island, it's already taking shape, but the habit has been formed, and I can't stop. What's more, when the results of the exploration teams are constantly being summarized, who still doesn't know what Sado Island represents?

That's absolutely unsafe even if you look at it. Not to mention one stone town, that is three stone towns, and it can't block all the roads.

So, how do you solve this dilemma? Only work hard.

If three stone towns don't work, then five; If five stone towns don't work, then ten. As long as you do too much, you can always block the road.

This is the same as the Goryeo people on the western peninsula, facing the threat of the Song army, they are also constantly piling up troops. Especially in Busan.

The second largest city in later generations was still a small fishing village at the present time.

Under the pretext of guarding against the Jurchens, the Song army smoothly cut off a few pieces of bloody flesh from the territory of Goryeo on the grounds that the Goryeo Dynasty had turned its back on Zhao and Song to claim to the Jurchens. Tamna Island is also, and so is Busan.

Goryeo has always been a vassal state of the Khitan, and it did not claim to Zhao and Song at all, but in the face of the Song envoy's questioning, no one in the government and the opposition dared to refuse. None of them expected that Zhao Song would be able to turn defeat into victory in the war, and not only did not suffer a big loss at the hands of the barbaric Jurchens, but instead pushed the Jurchens back and recovered the Sixteen Prefectures of Youyun in one fell swoop. The situation between Song and Jin was fundamentally reversed, which was completely unexpected by the Goryeo government and the opposition.

So, just like the obedient Jurchens who chose to be obedient at the beginning, Goryeo also offered his knees to Zhao Song.

But this in no way means that the Goryeo monarchs and ministers were willing to watch the Zhao and Song sides encroach on Goryeo day by day.

That's a lot more risk-conscious than the future generations of the 21st century.
