The current military strength of Zhenbei fort has changed greatly. From the earliest only 71 barbarian warriors to the present, there are 186 military strength, including the security team and recruits.

The security force of 30, the recruits of 40, the military order of 40, the soldiers summoned and the five scouts who have just completed their preliminary training, together with the barbarian guard, are the military strength that Suellen now has.

At present, the population of Zhenbei fort has exceeded 2000. Of course, more than seven of them are serfs of sulun. Even those refugees can survive by working for sulun.

Because of trade, several caravans come to Zhenbei Fort every month. Now the white sugar of Zhenbei fort is very popular in northern provinces. It is also because of the white sugar that high-grade rum has successfully opened the market among the nobles. It is nearly four months since Su Lun came to Zhenbei fort. This small town deep into the northern wasteland has also gained some popularity among the nobles.

As long as there is no accident, Su Lun, the development Lord, will become a real territory aristocrat. At that time, many aristocrats will come to curry favor with him. After all, a rising territory aristocrat can divide a large number of low-level aristocrats.

Su Lun didn't want to accept the help of those nobles at all. Those nobles must have lost their mind. He didn't intend to grant the nobles territory. Now he is busy harvesting food.

More than three months have passed since the first farmland was reclaimed. The first batch of potatoes have matured in about 100 days, and the remaining potatoes will mature in the next half month.

As long as this year's potato harvest is good and the output of potatoes is, even if potatoes are no longer planted in the next few years, there will be no famine in sulun's territory.

Of course, from next year, sulun will also reduce the planting of potatoes and plant some wheat and other grains. After all, he doesn't plan to eat potatoes, fried noodles with sauce, steamed buns and scallion oil cakes all the time. Isn't it delicious? If possible, why eat potatoes. He plans to try all kinds of delicious food in his previous life.

The first batch of cultivated land in zhenbeibao belongs to the best paddy field, and the land is also fertile. Although there is no fertilizer, the yield of potato is still very good.

When he came to the first potato fields, Suellen randomly selected several fields, and then let the serfs begin to harvest food.

"Sir, the land you have divided has been staffed," a servant came to Suellen and said.

Su Lun looked. The serfs on those lands were ready. Then he nodded, "let's start."

"Start!" shouted a loud soldier nearby. With an order, in these specially selected fields, the serfs began to harvest potatoes with various tools.

The soft soil opened, grabbed the vine and pulled it out, and a string of potatoes were pulled out of the soil. Shake off the soil, and the potatoes at least the size of a fist are connected into a string. It looks very gratifying. The weight of a string of potatoes is several kilograms.

Remove the vines from the potatoes and throw the fruits into the nearby bamboo basket. The potatoes in each piece of land will be weighed together. This is to estimate the yield per mu of the field to the greatest extent. Although there is still an error, there is little difference. Through these, we can roughly estimate the output of potatoes this year.

One mu of land is not big. These serfs are fast and want to make a good impression in front of Su Lun. As long as Su Lun is happy to reward them with a few points, they can get free faster and then own their own land. These people are very satisfied.

Soon, one mu of potatoes nearby were harvested. Sulun asked people to weigh them. Baskets of potatoes were screened and weighed after the soil was removed. The potatoes produced by each piece of land were weighed and marked one by one.

Potatoes are widely planted in the world, and the vast majority of civilians' staple food is potatoes. Who makes this as easy to grow and high yield? Only a small amount of land will grow crops such as rice and wheat, which are usually used to pay taxes. Moreover, rice and wheat are basically enjoyed by nobles or big businessmen as daily food.

The world's tax revenue is not low, because the local taxes are defined by the Lords. It's better to be kind. Those greedy will collect all kinds of taxes, catch fish in the river, cut firewood in the mountains, and pay poll tax every year. In short, they will collect all kinds of taxes from the aspects of clothing, food, housing and transportation.

When farming every year, you must complete the cultivation of the noble's land before you can plant your own land. You have to work for the Lord three days a week. If there were no potatoes, half of the civilians in the world would starve to death.

About half an hour later, the potato output of these lands was counted. The largest land had 303 kg of potato output, and the least land had 254 kg of potato output,

The output of more than 200 kilograms is not too high, because it is a new land. The output in the first year is slightly lower. When there is farmyard fertilizer next year, the output will be higher. Even now, the output of these lands is enough to feed tens of thousands of people. Moreover, potatoes can be planted three seasons a year, so he doesn't have to worry about food for a long time.

After the grain is solved, Su Lun can increase the intensity of population introduction. At least 300000 mu of good farmland can be reclaimed here in Zhenbei fort, which can feed 50000 or 60000 people. Now only about 10000 mu has been reclaimed. He doesn't intend to leave those lands empty.

The geographical location of Zhenbei fort is still a little remote, but if it was not so remote, this land would not be developed by him, and it would have been occupied by others, so there is no complaint. If Suellen wanted population, he had to rely on caravans to bring some refugees every time, or go to kart city to buy slaves by himself.

However, both of these methods cost a lot of money, and the effect is slow. Unless Su Lun is sure to get a recruitment order every once in a while, this is the best way.

For those drow elves, sulun also wants to accept them. Drow elves also belong to a powerful race, and compared with the obvious shortcomings of barbarians, drow elves have almost no shortcomings. Of course, if they are not dark girls of faith, sulun dare not accept these drow elves.

In addition to the drow elves who believe in dark girls, nine out of ten drow elves are mentally ill in Su Lun's view. Every day they are all kinds of intrigues and murders. It's better to practice riding more when you have time.

So far, Su Lun still hasn't taken the initiative to contact those drow elves. He has experienced escape and finally settled down. These drow elves are actually very sensitive and insecure. Moreover, they have lived in that kind of treacherous environment for a long time, which makes it difficult for them to trust others. Su Lun's best way now is to express some goodwill to them, but not too close.

In fact, Su Lun has regarded these drow Elves as the meat of his mouth. For those drow elves who live in the dark world all year round, nine times out of ten they can't adapt to the environment of the northern wilderness. It's impossible to imagine how cold the Northern Wilderness is in winter.
