The land near the Duke's Castle is not very suitable for farming, unless there is a particularly good wheat seed, but as far as Green knows so far, the wheat production in this world is very average.

And among the fantasy plants, there is no such thing as wheat.

Therefore, it is very uneconomical to grow wheat in the ducal manor, which consumes a lot of resources and can only get a small return, so it is better to buy it directly from the Chamber of Commerce.

It can be purchased from the Chamber of Commerce, which involves external transactions, and after all, it is not as good as self-sufficiency.

And it's a staple food, so it's not good to rely too much on the outside.

The bread tree is a perfect solution to this problem, the bread tree fruit can completely replace the white bread, whether it is hunger, nutrients, or taste, the bread tree fruit is slightly stronger than the white bread.

At the same time, the yield of bread trees is not inferior to that of the world's wheat.

Just one bread tree can be used by all the current owners of the ducal castle, and if the number of people in the ducal castle increases, then some more bread trees can be cultivated.

Green decided to build a separate base for the bread trees, not far from the Sivir Red Pepper base, which is also an area of one square kilometer.

An adult bread tree requires 100 square meters of land area, and one square kilometer can grow nearly 10,000 bread trees, which can provide food for tens of thousands of people.

Of course, this is done with careful care, and if the bread trees are allowed to grow naturally, the yield of the bread trees will be reduced considerably, but in any case, it is completely sufficient for the ducal castle.

Green wants to run the Duke's Castle, but it is not simply an increase in numbers, but an increase in talents, and it is enough for someone to do it in all aspects.

In Green's imagination, the Duke's Castle only needed a few hundred people.

This may sound like a small number, but on the one hand, because the area of the Duke's castle and the Duke's manor is not very large, it does not require too many people, and on the other hand, because Grimm is a wizard.

Since he is a wizard, there is no need to leave a lot of work to humans.

For example, the first line of defense of the Duke's Manor is completed by using the Thorn Vine, a fantasy plant specially designed for defense.

And if there were no thorn vines, hundreds of people, or at least dozens of people would be needed to patrol back and forth around the fence.

A thorn vine greatly reduces the need for manpower in the ducal castle.

After building the Bread Tree base, planting the Bread Tree Seeds, and performing the first ripening process, Green made her way to the wall, where Sally was rituring the Thorn Vine.

"Your Excellency. ”

Green nodded, giving him a slight look.

At present, the thorn vine has covered a lot of walls, a full three meters, crawling with blue-green rattans, and from time to time there is a certain flying insect creature passing by, which is whipped down by the thorn vine.

At the beginning of the wall, this part of the thorn vine is close to adulthood, and the rattan is thick and has hard barbs on it, which ordinary people can easily defeat it.

Grimm thought about it and removed a piece of rattan.

The next moment, Grimm chanted the incantation, and a flame rose from Grimm's fingertips.

Green placed the rattan on top of the flames.

In an instant, the thorn rattan writhed violently, and after a long time, the thorn rattan lost its vitality, and when the water was dried, the thorn rattan burned, and after a while, it turned into ashes.

Green nodded in satisfaction.

Green uses a magic flame that burns more than ordinary flames, but this thorn rattan lasted a long time before it was burned, proving that it is not so easy for ordinary flames to threaten thorn rattans.

The weakness of the thorny vine was smaller than Green had expected.

Then Green took two thorny rattans to the beach of the manor.

The coastline encased by the Duke's estate is not long, but it is not short either, except for this sandy beach, the two parts above are rocky and overgrown.

Grimm is going to strengthen the defense of this part of the area, except for the beach part, all but the beach part is planted with thorn vines, so that no creature has a chance to get close.

At present, the defense facilities of the Duke's Manor are not very perfect, and the land part has a three-meter-high wall, which can barely prevent some people from stealing into the Duke's Manor, but as long as you use tools or have better skills, the wall is not a problem at all.

But when the thorn vines on the wall are all adults, then they will be able to block most people.

The part of the coastline is easier to breach than the wall, and anyone can easily climb ashore and enter the ducal manor as long as someone sneaks through the water.

Originally, according to Green's plan, this part of the coastline should also share the same thorn vine as the fence part, and the benefits have been said by Green before, but the disadvantage is that it is too slow.

It will take a long time for the thorn vines in the wall to extend to this side of the coastline, and the two thorn vines also have the benefit of two thorn vines.

That's the question of the openness of permissions.

The permissions of the same thorn vine are the same, but the permissions of different thorn vines are different.

There are currently only two people on the thorn vine on the fence who have permission to approach, one is Grimm and the other is Sally, and the others, whether it is Eliam or Vivien, will be attacked by the thorn vine if they get too close.

The people who need to be close to the coastline are different from the people who need to be close to the fence, and the two plants can control the authority very well, so as not to give people too much authority.

Reaching a person who can be close to the coastline does not necessarily have to be able to get close to the wall, and a person who can be close to the wall does not necessarily have to be able to get close to the shoreline, which is conducive to the safety of the ducal estate.

And then Green got to work.

The end of the wall is the starting point and ends at the beach, in front of which is the sea, with a total width of ten meters, and in the middle of the green makes a groove three meters wide and two meters deep.

When the time comes, it will be covered with thorn vines, which can barely be regarded as a trap.

On both sides of the groove, there are many pillars that can be climbed onto by the thorn vines, increasing the defense height of the thorn vines.

When all this was done, Green began to ripen the thorn vines.

A letter cardinal stayed in front of Green, a little carelessly, and was whipped by the thorn vine, and fell to the ground, almost failing to get up.

But fortunately, the thorn vine is only in a state that has just been ripened, and it has not yet been able to adapt, so the force of the volley is not very strong, and after a while, the cardinal is flying again.

Throwing a letter in front of Green, and not bothering to beg for food, Cardinal immediately turned away.

Green opened the letter, and the letter was written by Charlotte.

There is only one sentence above.

"Kisti is not dead, drowning is a pretense. ”

Green frowned.
