For Qian Rujun, collecting local spices back is really a business with no capital.

When the spices are dried and turned into powder, they are not only better flavored, but also concealed from the outside.

Besides, the volume after making powder will be very small, and it is not cheaper to sell it back than the original things grown by Dahan.

Under the tropical sun, these spices also taste more pure.

After all, spices are not common in Dahan, and they have not yet fully expanded, so the price of these things is still relatively high.

It's just not like the offspring, where a bag of star anise is exchanged for a bag of gold.

Since he had the idea of setting up a base, after returning to the outside world and entering the bookshelf space, Qian Rujun redevoted himself to the work of drawing longitude and latitude lines.

She had to take the nearby island, or the city of Houshi, and find out its coordinates in order to find the largest island, Borneo.

Or find Sumatra.

With relative position, it's much easier to determine where you are.

After all, in daily life, few people will remember the coordinate points.

Thinking of the tsunami that occurred one year and flooded the coast of Sumatra, leaving many people washed away by the sea, Qian Rujun felt that it was safer to find Borneo, because the island was relatively large and had a relatively large inland area.

Of course, in the 21st century, due to Malaysia's relatively small population and relatively late development, there is still a lot of rainforest in the core of Borneo.

However, if Qian Rujun set up a base here and let the Han people breed in large numbers in this place, perhaps the population here will exceed 100 million, and the environment of the tropical rainforest will undergo a lot of changes.

Perhaps the environment of future generations will also change dramatically.

As for the Europeans, they say that the tropics are not suitable for human life, but this is actually a wrong concept.

In tropical places, the temperature is around 26 degrees, and there is almost no change in the four seasons of the year, which is most suitable for human survival.

So that a person will not sweat a lot at all, and can sleep well at night, this kind of environment is basically the temperature of the air conditioner set by Qian Rujun in the summer.

As for what Europeans say, the most suitable temperature for human survival is 16 degrees, and that is 16 degrees in Europe, so they can feel warm.

Europe is the environment, not the most comfortable place.

It's just that the equatorial region is suitable for human survival and at the same time suitable for the survival of a large number of creatures, so the ecological environment here is very abundant, and it rains every afternoon.

Many people think that because the rain will lose nutrients in the soil, it is not very good for the development of this place.

However, the pristine nature of the rainforest is good, but the fact that they grow coffee in the European way is problematic.

In many places, all of a sudden, it becomes desertification.

Creating a desert in the rainforest, the Europeans did it.

But later generations of Asians held on to the land of Borneo.

It's not that it doesn't grow coffee, but it produces more food, and there are Asian-style farming methods, which makes this place different from Africa and America.

If Qian Rujun controls the world, she will not let what Europe did happen again.

Although it was very difficult to make the Han people clean, even if they were taught a hygienic lifestyle and there were no harsh punishments, many people still did the same. No rules can be formed.

Even in Jinmai City, there are not a few people who are punished for being filthy every day, and they have become one of the important incomes.

A large number of geography textbooks mention that the tropics are not suitable for farming, but Qian Rujun thinks that the European way of farming is wrong.

They worship specialization too much, and as a result, they deplete the land of nutrients while increasing efficiency.

And this depletion, in the beginning, not all nutrients are missing. Rather, it is partially depleted.

Because the same plant can only absorb the same nutrients.

So in Europe they used crop rotation, but in other places they forgot about crop rotation.

Moreover, the rain in the tropics is not comparable to them in Europe.

If it is a Han people, no, if the Han people after the Tang Dynasty come to this land and use so much rainwater to open up paddy fields, there will be no problem of soil loss at all, and there will be no problem of large drops of raindrops hitting the ground and causing nutrient loss, because these paddy fields themselves are a protective layer.

The nutrients in this place are not only not lost, but can also be accumulated slowly, and of course, the most important thing is that the farming technology of the Han people can overcome the production obstacles in this place.

They also replenish nutrients at the same time as they obtain them.

The only thing that cannot be overcome is that in this place now, the power of nature is still relatively strong, and in the case of the relatively strong power of nature, a large area is still a space for poisons to live.

It is necessary to remove a large amount of the space in which the poison exists, so that the poison is far away from the place where human beings live, so that human beings can have hope of survival.

That is to say, it is necessary to wage a war of survival, and the time when the war of survival is launched is not a battle between man and man, but a battle between man and nature.

At this time, it is obvious that man is weak compared to the forces of nature.

That is to say, it is not suitable for the hard-working people of the Han Dynasty to live now.

The working people of the Han Dynasty can be very violent, but that must be when they have no way out, and now, the mountains are full of land, and they don't have to vent their ferocity in this place at all.

The working people of Dahan attach great importance to the benefits that can be seen in front of them.

In Borneo, the forces of nature are so strong that they overshadow the brilliance of the Han people, and under normal circumstances, they would not have chosen this place at all.

The power of nature will make the Han people face opponents that they simply cannot understand, and only a large number of deaths will they be able to get the wisdom of survival from within.

This wisdom must also be generated by their intentions for this place.

Illness and death in it made the Han people, whose population is still small, unbearable.

Qian Rujun remembers that in fact, the population of the Han people grew rapidly, but every war was able to kill many people.

Epidemics and famines can also kill people. It's really not easy to survive.

Therefore, the power of nature must be erased in order for the Han people to survive smoothly.

For nature, human beings are both a help and a destroyer, of course, in most cases, from the perspective of future generations, human beings only have a part of destroying nature, of course, in the current situation where there are relatively few human beings, human beings are actually part of nature, under the control of nature.

Only the control of local areas is feasible for human beings to know.

From a point to a surface. It's very simple to say, the danger is very high when humans only exist in dotted settlements.

Only by meeting the surface can we survive in the group.

When people fight against nature, they actually pay a lot of price, and as a result, some people are left to survive.

After we defeat nature, without many natural predators, human beings continue to expand, nature faces the biggest challenge, and when nature is almost extinct, the power of counterattack is also increasing.

However, at this time, the most terrible enemy of mankind is still human.

Finally, humanity has developed to possess the capacity for self-destruction.

After all, there is no way for humans to survive in this land with such a large population.

Because in fact, there are too many people in this world, too many people, and the world can no longer be fed, and people must fight for survival space at this time.

Qian Rujun began to start construction and did the right thing, and the few people who drew the map, of course, would not continue to repair the ship there, but hurried over to draw a new follow-up map.

The most important thing is that all they have to do is know where they are.

It is expressed in an absolute positional way.

Then Qian Rujun will be able to see the relative position.

After they came to the coral reef island, they had already quickly observed the latitude and longitude of this place.

It is not difficult to check the latitude and longitude, the most important thing is to look at the sun, and then do the conversion, although it can not be done, it is really very accurate, but at this time it has been able to help a lot.

At least Qian Rujun saw this latitude and longitude, probably knew the location of this island, and knew how far away the location of this island was from the nearby islands, so he could judge according to the map the direction the ship would go next and the time it would take.

"It's still so far away, I thought there should be islands nearby, but although there are no big islands nearby, there are still a lot of small islands in the area, and this place is very close to Sumatra, which is a bit different from my purpose. ”

Qian Rujun sighed sadly.

In the past, Qian Rujun's idea was that the best position was the location of the strait, and controlling the strait could control the ships along the coast, but Qian Rujun also knew that at this time, not to mention Europe, even Asia, there were no ships coming and going in this sea area, so the necessity of building a city in the strait was not too high now.

This is because the location of the strait is not necessarily suitable for the cultivation of farmland.

Although at this time, even if this place did not farm, it could feed hundreds of thousands of people, Qian Rujun knew that if he forgot the farming technology and did not have a stable income, it would be a devastating blow to the Han people.

, can only be said to be the goal of the future, it is better to be able to occupy Borneo, why not occupy Sumatra, the main reason is that Sumatra is also part of the Pacific Ring of Fire, that is to say, this place is a plate squeeze zone, there are a lot of earthquakes and tsunamis will occur.

Moreover, the ground is not flat, which is actually very unsuitable for large-scale agricultural development.

And there is a lot of land that cannot be used, comparatively, the land in Borneo is much better.

He belongs to the remnants of the mainland, and there are many places, which are actually very flat.

Qian Rujun decided not to change his goal, but the distance to Borneo was much longer than that of Sumatra.

Originally, Qian Rujun wanted to send an army to deal with the problem of people first.

Now, the aborigines living there are relatively scattered, and it will not be too difficult to break them down.

As for large countries, they may rule over a large area, but there is no way to govern such a place.

The ability to rule in this era is very good to be able to achieve stable control.

Often, there will not be a very large force, for the Han Dynasty, 100,000 soldiers is a normal thing, but for these places, a total population of 100,000 is a normal thing.

Even with a total population of 100,000, there was no way for them to extract most of the population to fight for them.

Because they have to have more people in charge of production, and in this era, a large part of the population is children.

You must know that there are more than 30 million people in the Han Dynasty who can support 100,000 troops, and the army will also be unorganized.

If a small tribe with only 100,000 people wants to support an army, even if it is relatively useless, it can support a few more, but the number of people must not be large.

If you want to start a business in another place, one way is to use the method he used to use on the island, and it is recommended to use a business model to let her get used to you.

But there is another, easier way, and that is possession, and as long as possession, force is required.

Qian Rujun looked at the sailors who were already familiar with the navigation of the water conservancy department, and knew that these people had to be put into battle.

Of course, Qian Rujun will let the professional people enter the battlefield first, and the professional people are the students of the academy, but the students of Xuetang Island are not all around him now, and there are only two or three hundred students on Xuetang Island beside him.

It's a bit of a lonely.

The students of Xuetang Island can fight against two or three thousand people with one against ten.

If you fight hard, you can deal with about 6,000 people.

Qian Rujun assessed it, and this should be feasible.

It's just that they won't want to leave her.

Of course, they will not violate Qian Rujun's requirements.

As long as someone stays.

In fact, Qian Rujun really wanted to send a group of people to do things first, so that all the people would not be stranded here and waste time.

She believes that Borneo does not have too strong people, because in her memory, life in Borneo is actually leisurely, if no one oppresses them, in fact, there is no need to rely on anything in life, you can eat the fruit of the tree when you are hungry, you can drink the coconut from the tree when you are thirsty, find a cave to nest in the rain, and wait for the rain to stop.

The rain doesn't go on and on, and it's only for the last few hours of the afternoon.

In addition to sleeping at night, there are more mosquitoes, there is no problem of heat and cold, in many cases, in fact, this is actually a kind of paradise.

As for the problem of heat and disease that the Han people are not used to, many people in this place already have antibodies that will not be affected. Many children have already acquired antibodies when they are sick when they are young, and those who can't survive have already died.

If they don't have antibodies in another place, they may be affected, so they generally don't come and go in this place and move around.

In other words, as long as you control the local people, you can ensure the safety of a place. Wait for the manpower to arrive, and then gradually expand.

"The armed groups in that place, there will be no more than a thousand people. ”

Qian Rujun muttered.
