Every year, Wu captured a lot of Kunlun slaves from various islands in Southeast Asia, such as Wa Island, Java Island, and Malay Island.

The dark-skinned Kunlun slaves were actually used by Wu as free labor.

What's more, for example, women have been assimilated and become concubines of the Wu people, reproducing offspring for the Wu people, and spreading branches.

For Wu Guo, the more Kunlun slaves the better.

If the common people of Wu want not to serve the labor, they have to pay a change of payment, and let the Kunlun slaves serve the labor instead of them.

All kinds of dirty talk and tiring work are also handed over to Kunlun Nu to do, and you don't have to feel distressed when you die.

So far, there are probably more than a million Kunlun slaves in the state of Wu.

The footprints of Wu's fleet have spread throughout Southeast Asia in the past 20 years.

According to the navigator of Wu and the map drawn up, Qingji estimated that Wu's caravan had reached as far as the Atlantic Ocean and Australia.

This is the Eastern Route.

On the northern route, Wu's caravan reached as far as Alaska in later times, probably in the cold Arctic Ocean.

The southern route reached the Persian Gulf and opened exchanges and trade with the Persians from the sea.

This is the famous Maritime Silk Road.

"Father, according to your instructions, my sons have drawn the eastern route of my Great Wu fleet and the coordinates of each island into a nautical chart, please take a look!"

Childe clapped his hands immediately, and two guards carried a patchwork navigation chart and placed it on the huge floor, allowing Qingji to look at it.

This nautical chart, sadly called the "Pacific Nautical Chart", there are still many islands that have not been explored, but so many islands can be discovered by the Wu fleet, and so many savages have been captured.

It's not easy.

"Father, half a year ago, the caravan led by Erchen discovered a new continent in the east, hanging alone overseas, I don't know how big the land area is, Erchen estimates that the area on this chart is only the tip of the iceberg of this new continent."

Hearing this, Qingji nodded, very satisfied.

The "new world" in Childe's mouth is Australia.

"Sorrow, have you seen the world map that the widow gave you?"

"I've seen it."

Gongzi frowned slightly and said, "The world is so big, it is indeed wonderful. The fleet of my father and his sons sailed across the oceans, and they were struck by strong winds and waves, and stormy weather, and they almost did not return, and five ships were damaged, and a hundred and twenty-six died."

"The fleet finally landed in the New World, but we had to return because of the lack of food and the fact that many of the people on board were sick with necrosis."

"However, Erchen has left more than 500 people in the New World, and the next time Erchen will be able to cross the ocean again and find the American continent that your father said."

Being able to explore Australia is already a great thing for Wu's fleet.

After all, although the shipbuilding industry of Wu was developed, it was still stuck in the era of sails, and initially had the ability to cross the ocean, but it was difficult to resist natural disasters.

In the event of a storm, the ship runs aground, or is swept up in a whirlpool, most of the people on board will never return.

[The app that has been running stably for many years is comparable to the old version of the book-chasing artifact, which is used by old bookworms.]

Corn, potatoes, and potatoes are all relatively high-yielding crops, and they are very popular."

"And this kind of thing?"

Childe was a little confused.

In fact, Qingji is not sure if there are any remnants of Yin Shang living on the American continent.

As for corn, potatoes, and potatoes, it is true.

"Father, if we follow the world map you gave, wouldn't it be better for my Wu Kingdom to send someone from the Arctic Ocean across Iceland (Alaska) and then all the way south by land?"

「……」

Qingji was quite speechless and said, "The cold weather there is not something that ordinary people can bear. In addition, the fleet is prone to running aground, and in order to explore there, hundreds of people died in the seabed, or were frozen to death."

"The bad weather has become the biggest opponent of my Dawu sailing fleet."

"Besides, crossing from Iceland to the American continent in the south, all the way to the mountains and roads, the widows may not be able to wait for that day, and they may not necessarily return to Dawu and return to their lives with the widows."

The truth is obvious.

Reaching the American continent is already not easy.

In case the people who get there don't come back directly, play for Qingji to disappear, establish a kingdom on the American continent and become king, marry a wife and have children, Qingji can't help them.

Isn't this a wedding dress for others?

In view of this, the leader of the fleet sent by Qingji is basically his own son.

In this way, it is his own son who is the king of the overseas country, and Qingji can still accept it.

"Sorrow, this new world...... Are there any aborigines on the Australian continent?"

"Yes. And quite a few."

"Oh?"

Qingji suddenly became interested.

After all, in his cognition, in the original history, the Australian continent was a place where the English sent criminals, and the people who lived there were basically Caucasians.

Of course, there are indigenous people, but their presence is too low.

It is said that as early as 40,000 years ago, people settled on the Australian mainland.

They are not really "native" Australians, and the aborigines there are also immigrants.

The aborigines of Australia belong to the Neglito race, which is a cross between various primitive races in East and Southeast Asia.

Anthropologists believe that they may have appeared during the recent Ice Age.

When they arrived on the Australian mainland, because the sea level was low at that time, there were land bridges between the islands, and the water surface between some straits was relatively narrow, so it was easier for them to come to the Australian mainland.

However, after the Ice Age, some Negritto ships entered the Australian mainland, and the time is much closer to now.

"Father, son, this time, a total of more than 20 tribes on the Australian continent were wiped out, and more than 6,000 Kunlun slaves were captured."

Gongzi replied, "These natives live the same nomadic life as Rong Di, living by hunting kangaroos and other animals, and using wild plants, nuts, berries and other supplementary food."

"However, the combat effectiveness is really poor, and I don't need to fight."

How can the combat effectiveness of the natives be comparable to that of the regular army of the State of Wu?
