Just when Marin was hiding in the room and secretly planning to kill all the great nobles of England, there was a knock on the door. The current secretary, Machiavelli, reported that Prince Sigismunt, the quasi-son-in-law of the Hoffman family and the crown prince of the Grand Duchy of Poland and Lithuania, had arrived in the Grand Duchy of the North Sea with a large team. His intention seems to be to make a formal marriage contract with the Hoffman family and make a covenant.

Last time, the team sent by Grand Duke Alexander to Worms was only to support Marin, and it was not officially engaged. Now, instead of being beaten to death by the group, Marin has gained a foothold, and Grand Duke Alexander naturally feels that it is time to sign a formal marriage contract.

After all, Marin was just Anne's second brother. If you want to marry Anne, you must talk to Anne's parents, the old Hoffmans, and make a marriage contract with the old Hoffmans.

This time, the army led by Prince Sigmunt was very large, in addition to two thousand guards and knights, there were several thousand attendants, driving 20,000 cattle and 5,000 horses.

Prince Zygmunt was a smart man, and he knew what Marin needed. Previously, when he was in East Friesland, he had heard that Marin had advanced agricultural technology, advanced fertilizers, and a method of taming cattle on a large scale to cultivate the land.

It just so happened that this year 10,000 cattle and 5,000 horses used by the Crimean Khanate and Marin trade crossed Poland. So, Prince Sigismunt simply added 10,000 cows to give Marin a gift. First, it can be regarded as confirming the marriage between himself and Anne. Second, it can be regarded as congratulating the second uncle on becoming the Grand Duke of Beihai...... In addition, Prince Zygmunt also intends to form an alliance with Marin......

Finally, and most importantly...... That is, Prince Zygmunt wanted to take advantage of the autumn harvest to confirm whether the rye harvest in Marin's manor was really that high......

After all, what Marin said was too mysterious. Four or five hundred pounds per mu! Compared with the average European field, the yield per mu is more than 100 pounds, which is simply a myth.

So, taking advantage of this opportunity, Prince Zygmunt decided to go to the fields to watch the serfs of Marin harvest, and to weigh the grain produced per acre of land by weighing it himself. (Note: Prince Zygmunt's last visit to East Friesland accepted the measure word of East Friesian acres and the term 'yield per acre')

This time, Prince Zygmunt came with no gold or silver treasures, and he didn't bring those precious works of art. Because he knew that Marin was not interested, and the rest of the Hoffman family was not very fond of it. So, apart from a few fine pieces of jewelry to please his mother-in-law, Lady Mary, and his future wife, Anne, Prince Sigmunt brought only 10,000 cattle, as well as 10,000 cattle from the Crimean Khanate and 5,000 Eastern Mongolian horses.

He knew that the second uncle had mastered advanced agricultural technology, and now that he had obtained so much new land, he would definitely need a large number of ploughing cattle to clear the land. Therefore, bringing cattle is more popular with Marin than with gold and silver treasures and works of art.

Sure enough, when Marin learned that 20,000 cows and 5,000 Eastern European Mongolian horses were coming, he couldn't be happier. He was planning to develop Jutland in a big way, and there was a shortage of livestock, especially cattle. Therefore, these 20,000 cows are really a solution to the urgent need.

There are also the 5,000 Eastern European Mongolian horses, which Marin also needs to build his future Cossack village.

Therefore, Alin personally took a ticket and went to the East City Gate to warmly welcome Prince Zygmunt. Then, to the great embarrassment of Prince Zygmunt, Marin went to see the Eastern European Mongolian horses...... Moreover, Marin bent down to observe the PP of those Eastern European Mongolian horses, which seemed to be very obscene......

In fact, Marlin was looking to see if those horses had been castrated......

Many of the 1,000 war horses purchased from the Crimean Khanate last time were castrated and could not be bred as a horse at all. Therefore, later Marin demanded that the castrated horses not be accepted, otherwise they would not be paid......

Crimea is probably really short of money, so, this time, Marin did not see the castrated horses......

It's no wonder that Ma Lin is so careful, but he is until, in ancient China, when the Central Plains Dynasty was trading tea and horses with the northern nomads, the northern nomads were cunning. In order to be able to carry out this kind of business for a long time and avoid the Central Plains Dynasty breeding a large number of horses by itself, most of the northern peoples used castrated geldings when they exchanged war horses for tea.

In this way, even if the Central Plains Dynasty got a good horse, it could only use one generation. When the war horses are old, they have to go to the grassland people to exchange with each other. Otherwise, there are no new good horses......

Marin was also worried that the Crimean Khanate would be like the Mongols who traded tea and horses with the Ming Dynasty, and that they would use geldings to fool them, so he specifically asked for uncastrated ones. Moreover, the reason is not that they want to train new Eastern European Mongolian horses, but that European knights are not used to riding geldings...... This argument does hold water, and many European knights did not like to ride geldings. Therefore, the Crimean Khanate did not doubt him. Moreover, their region is also short of money, plus Marin's territory and the Crimean Khanate do not border, there is no conflict between the two sides. Therefore, they don't care about selling uncastrated Eastern European Mongolian horses to Marin......

Prince Zygmunt looked speechless at Marin bending over and staring at the horses, a little embarrassed. Fortunately, the casual Jeffrey palace minister was very good at things and entertained Prince Sigismunt well so that he would not be embarrassed.

In the evening, in order to entertain Prince Zygmunt from afar, Marin held a grand dinner and court ball in the royal palace, and signed the marriage certificate in public, officially engaged.

But the next day, Prince Zygmunt also strangely refused Marin's hospitality, saying that he would personally go to Marin's estate to personally participate in the harvest, and personally supervise the scales and observe the rye yield......

Marin knew that Prince Zygmunt was a little skeptical of his words, so he simply asked a team of guards to accompany him to a farm not far from the city of Aurich, and asked the prince to go down to the field himself to participate in the harvest, and help him count the grain yield per acre, so as to satisfy his curiosity......

So the honorable Prince Zygmunt, the future King of Poland and Grand Duke of Lithuania, dressed in linen labor clothes and carrying a sickle, joined the army of harvesters in the rye fields of the estate......

Prince Zygmunt took part in the rye harvest on several estates in the days that followed. Of course, after grinding the blood blisters on his hands on the first day, His Royal Highness did not personally participate in the harvest, but he supervised the harvest of the serfs by the side, and went to weigh the rye with a few guards......

A few days later, he finally confirmed that the rye yield of the estate in Marin's name had indeed reached about 500 pounds, which was very impressive......

If the second uncle is willing to provide that kind of magical fertilizer to himself, then he can also make a fortune by farming...... Prince Zygmunt couldn't help but fall into YY......
