After seeing off the officers of Spain and Teutonic countries, Marin immediately turned his attention to the construction of the country. Since an agreement had been reached, the 18,000 Saxons would be young and strong, and they would be Marin's private serfs in the future.

As a feudal landlord, how could Marin tolerate these people having idle meals? So, Marin immediately broke up the 18,000 strong men and reorganized them and began to form a construction team. Because Marin planned to dig trenches and dig them...

Of course, Marin also has another task - to expand Orich City. As the capital of East Friesland, Orich naturally cannot be as small as before.

Moreover, the palace where Marin lives is too narrow and dark. Marin also plans to expand the palace, at least to expand it into a place with a large garden.

At present, no farmland has been reclaimed around Orich City. Therefore, Marin has expanded the city without requisitioning farmland.

Although digging trenches and digging canals is important, Marin felt that building new cities is also important. Therefore, Marin decided to divide a group of people into the 18,000 young and strong men to expand the city of Orich as a construction engineering team.

To this end, Marin specially sent people to pick out about 3,000 people from the 18,000 young and strong people who knew the skills of masons and stonemasons, and formed a construction engineering team separately. As for the other 15,000 people, they formed a land reclamation team, responsible for digging trenches and clearing swamps...

In addition, Marin estimated that the Duke of Saxony would definitely give priority to redeem those knights. Therefore, the 7,000 regular infantry prisoners of war would not leave for a while.

Marin naturally would not raise them in vain. Therefore, under the supervision of soldiers, these 7,000 regular infantry prisoners of war were also pulled over to be coolies by Marin...

As for those knights, Marin wanted to send them all to the ground to work. However, Marin was afraid of being criticized by the European nobles, so he finally gave up this tempting idea. Last time, Marin asked the musketeers to hammer a large number of heavy cavalry in front of the formation, which had already caused many people to criticize. Then, he sent the knight captives to the ground to be coolies, and it would probably be hostile to the knight class. Therefore, Marin had to raise these people first.

Of course, Marin would not serve these old men with delicious food and drink. Usually, they just let them eat some black bread. Moreover, these black breads were not black bread made of pure rye that Marin ate in his army.

The 18,000 young and strong coolies were not pure black bread. But because they were afraid of hurting the teeth of these coolies, Marin ordered that the black bread should not be mixed with stones. In addition, Marin also prohibited the addition of soil to the black bread. Because the soil cannot be digested after eating it, it will affect the work.

However, Marin could not eat pure black bread for prisoners of war. So, what adulteration should be used? There must be wild vegetables, which are originally food, and can also increase vitamins. Wood chips can also be added, and they are also rich in cellulose...

In addition, Marin has also launched a new cheap additive ingredient - grass bran...

In my previous life, I lived in the countryside and raised pigs at home. Before the popularization of pig feed, I often used bran to feed pigs at home. There are two types of brans - one is chaff, which is obtained by crushing rice husks. This bran is very nutritious and is very good feed. Similarly, wheat bran is also a kind of important grain in Europe because of the low grain yield, wheat bran is also an important grain, mixed with flour and made into bread. Even the "pure" black bread eaten by ordinary people is wheat bran. Only the pure black bread eaten by nobles are separated out.

As for another conventional raw material for pig feeding, it is the grass bran obtained after crushing straw or wheat straw. The nutritional value of grass bran is far from being as good as that of grain bran, but it is also a little nutritious. Before the feed of rural pigs was popularized, the most common thing for pigs at home was grass bran. As for grain bran, it is considered the "essence" of pigs. Of course, fattening pigs are not eaten because they are not fat after eating. Generally speaking, grass bran is for old sows. Because old sows do not need much nutrition when they are not born or fed, they are enough as long as they are not hungry. Only when they are pregnant and feeding, they will instead feed higher nutritious grain bran.

In other words, grass bran is a thing that can help you with hunger, but it has no nutrition. Although the black-hearted Marin prohibits the bread from being mixed with gravel and soil, he quietly ordered people to mix grass bran in cheap black bread...

After all, the cost of grass bran is extremely low. The raw materials for producing grass bran are those rye straws that are used as fuel for rural earth stoves. However, one thing that makes Marin a headache is that grass bran raw materials are easy to obtain, but processing is difficult in this era.

Because Marin does not have a high-speed rotating crusher in his hand, he cannot quickly break the rye straw into grass chaff. Therefore, the current method of processing grass chaff is still very primitive stone grinding - that is, put the dried rye straw on the stone grinding...

However, it is really difficult to grind rye straw into powder. It would be good to put ten kilograms of rye straw on it and grind one kilogram. If it were replaced with more difficult straw, Marin would probably not be able to grind half a kilogram of grass bran. After all, wheat straw is more crisper than straw, and it is relatively easy to grind. Fortunately, Marin has built many Dutch windmills that drive stone mills, which does not require much manpower. Then, rye straw is everywhere. Although it is a waste of time, adding grass bran to black bread is an excellent business that saves costs...

Originally, Marin was still very uneasy and felt that his heart was too dark, so he actually let the coolies eat bran. In order not to make the taste of black bread worse, Marin also specially instructed the bakers to add less grass bran.

However, Kohler, who was in charge of logistics, did something darker than him. Marin ordered to add 20% of the grass chaff to the bread, Kohler directly asked to add 30%...

In Kohler's opinion, Marin is definitely a genius idea to make people add grass bran to their bread. Moreover, Kohler thinks that adding grass bran is much more kind than adding stones and soil.

You should know that if the black bread with added soil and stones is almost as hard as a brick, it can be used to fight directly. It is very uncomfortable to eat.

But after changing the soil and stones to grass bran, the black bread is no longer as bricks and tastes much softer. Although it cannot be compared with pure black bread, it is much better than those "black stick" black bread.

At least, Kohler, who has eaten "black stick" bread for a long time, believes that black bread with grass chaff is more like food than "black stick" bread and tastes better.

In this way, with the insistence of Kohler, who was in charge of logistics, all prisoners of war, except for the knights, usually had a "mixed" black bread with 10% wild vegetables, 10% wood chips and 30% grass bran.

In other words, only half of this bread is rye noodles...

But what surprised Marin was that those prisoners of war who were born in civilians were not repulsive of this kind of bread at all...

This is also the kind of black stick bread that Marin has never eaten. The kind of black stick bread that can be used as a brick can be mixed with 20% of the soil. When this soil is dried in the oven, can it not be hard? Therefore, when eating black stick bread, you often need to use hot water to soften the soil ingredients, otherwise you will not be able to put it in...

The black bread mixed with grass bran is different. No matter what, grass bran can be eaten - although the grade is too low. However, for the poor people in the Middle Ages, the ingredients in the bread were all eaten, which was considered a good treatment. After all, grass bran can be digested by the stomach, but it is just not nutritious, but at least it is worth hunger.

Even Kohler planned to promote black bread with grass bran nationwide. Because this technology is too cost-saving. Swapping rye for cheap grass bran itself saves a lot of costs. For Europeans who advocate business, it is really cost-effective...

But Marin opposed letting his citizens eat black bread containing 30% grass bran, because he needed strong citizens. Although grass bran could be eaten, it was not nutritious. If the citizens were thin, when Marin needed to mobilize the citizens to join the army, the ones they collected were a bunch of thin monkeys with little strength.

Therefore, Marin did not object to Kohler's promotion of grass bran bread in China. However, Marin demanded that the proportion of grass bran be reduced by half, and changed to half...

This black bread with 15% grass bran quickly became popular in East Friesland and became a staple food for residents and fishermen in East Friesland. Then, this bread was also named "Korel Black Bread"...

As for the real original creator Marin, he thought the matter was very disgraceful, so he pushed the credit to Kohler who was in charge of the matter. But what surprised Marin later was that Kohler gained huge public expectations because he "invented" the cheap "Korel Black Bread" that was not bad, which made Malin a little jealous...
