As for what other families can research, it is not known, large machinery such as trains cannot be studied, but relying on manual work can still be made of relatively primitive firearms, don't underestimate people's wisdom, of course, even if the original firecrackers are made, there is not much threat to the Yun family's army, and the primitive firecrackers are not as good as bows and arrows.

The construction of the railway track is only one of the three developments under the Yun family, and the railway road is not fully completed, but will be opened after the construction of a section of the railway road is completed.

In Zezhou, Yunhua County, and Yingzhou under the rule of the Yun clan, the common people who made a living from farming accounted for more than 70 percent of the total population, and agricultural development was very important.

Thanks to Yunyi's "Land Reform", the common people under Yun's rule were able to get their own land, regardless of gender, 10 acres of land for those over 15 years old, and 5 acres of land for those under 15 years old.

In Yingzhou, with the increase in the number of fields reclaimed, the area of sweet potato cultivation is also rising, and the sweet potatoes produced in Yingzhou alone can fill the stomachs of everyone in the three places under the rule of the Yun family every year.

The high yield of sweet potatoes has led to a rapid decline in the price of sweet potatoes, but in terms of yield per mu, the income of planting sweet potatoes is still higher than that of planting grains.

A large number of sweet potatoes are transported from Yingzhou to Yunhua County and Zezhou, in view of the low price of sweet potatoes, ordinary people have sold their own harvested grains, and turned to buy sweet potatoes as food, the common people have more and more money in their hands while eating a full meal, sending their children to study in primary school is just the simplest thing, in addition to storing a sum of money in Yun's money village in case of emergency, the rest of the money will also be used to buy cattle, horses, repair houses, buy cloth to make new clothes, new shoes, and so on.

The life of the common people in the three places under the rule of the Yun family has moved from subsistence to well-off, and "well-off" is between food, clothing and wealth, which refers to a relatively stable life, and people can pursue a better life while eating well.

Life has settled down, there is food that can not be eaten, there is still a lot of money in hand, people with the idea of passing on the family lineage and spreading branches and leaves have to feed the next generation, a couple has a child is less, some couples have a child every other year, and "less" some couples will have children born every year.

A few years ago, the rebellion of the Bright Religion that affected the entire Zezhou led to a sharp decrease in the number of young and middle-aged people in Zezhou, and also led to a large number of women becoming widows, women always need to have men to rely on, a large number of widows with children to remarry others, the sexual welfare life of young adults in Zezhou began from this, as long as the life is not bad, most young and middle-aged men will have two or more wives, generally the better the life, the more wives, and the lazy people will not have women willing to marry past.

According to rough statistics, the birth rate of the population in the three places under the Yun family is about 10 percent. (The birth rate is high, but the death rate is also high.)

The population increased dramatically under the Yun rule.

When the common people under the rule of other families were still pursuing a life of food and clothing, the common people under the rule of the Yun family had entered a well-off life, and the well-off life was already the happy life that the people dreamed of, and it was also the life that people should have in the beautiful world that Yuan Xin once fantasized.

Even though the birth rate of the three places under the Yun clan is very high and the total population is increasing rapidly, the population base is too small, and when the Yun clan first took control of Zezhou, the total population under his rule was only more than 1.9 million, and the young and middle-aged people were pitifully few.

Population is the base, but also the war potential, and a large enough population can recruit more troops.

According to Yunyi's order, Tianmu and Xunfeng sent people to spread the remarks in the south of Laizhou and the west of Hezhou to spread the remarks such as "the people of Zezhou live a very happy life" and "everyone in Zezhou has their own land".

All in all, under the propaganda of Tianmu and Xunfeng, Zezhou has become a happy place, a land of hope, and such propaganda is not fake, and the people living in Zezhou also think that Zezhou is a happy place, and their current life is very happy.

One person is talking about the land of happiness, ten people are talking about the land of happiness, and countless people are talking about the land of happiness, then Zezhou has really become a place of happiness, and some people who live in areas very close to Zezhou have illusions, dragging their families and stepping into the land of Zezhou, and soon they will get their own land.

Subsequently, more and more people from Laizhou and Hezhou moved to Zezhou, but the five great families of Laihe and Hezhou also soon discovered this situation, and the five great families also understood the importance of population, and sent troops to prevent the people from leaving Laizhou and Hezhou.

Under the threat of the soldiers' blades, the common people had no choice but to return to their homes.

Although the five great families made a move, Yunyi's actions did not stop, and soon, the Warrior Guild issued the task of "relocating the population", regardless of men and women, anyone who migrated a person over the age of ten and under fifty to Zezhou can get one point, and each person who is under the age of ten and over fifty can get half a point.

As soon as this task was released, the registered warriors of the Warrior Guild were moved.

Since Ding Qi relied on the Martial Artists Guild to become promoted to become an Innate Grandmaster, in the past few years, three more Martial Artists Guild registered martial artists have been promoted to become Innate Grandmasters, without exception, these three people also refused to join the Yun Clan completely, but became the elders of the Martial Arts Guild, indirectly serving the Yun Clan.

There are four scattered martial artists in a row who have been promoted to congenital through the martial arts guild, this news is like a thunderbolt among the scattered martial artists of the Dali Empire, you must know that the possibility of a scattered martial artist being promoted to congenital is very small, I am afraid that there will not be one in ten years, there is no other reason, the lack of cultivation resources, that is, the lack of medicinal materials, the lack of high-year medicinal materials.

By completing the tasks of the Warrior Guild to obtain points, but can be exchanged for high-grade medicinal materials from the Warrior Guild, scattered warriors from all over the Dali Empire have gathered in Zezhou to become registered warriors of the Warrior Guild, and receive tasks from the Warrior Guild to gain points.

The large-scale task officially released by the Warriors Guild is the best opportunity for the warriors to gain a large number of points, and it is obvious that this "migration population" is such a task, and the warriors have heard the wind and formed teams to enter Laizhou and Hezhou, looking for various ways to migrate the people of Laizhou and Hezhou to Zezhou.

Although the five great families of Laihe Erzhou sent a large number of troops to block the migration of the common people, the border between Laize and Heze was so wide that no matter how many troops were sent, they could not hold all of them, and the warriors could even lead the common people into Zezhou through various paths.

Seeing a large number of people flowing into Zezhou, the five great families of Laihe Erzhou were extremely angry in their hearts, and they wanted to enter Zezhou, but none of the five great families dared to do so, even if they were united, the strength of the five great families was increasing, and the strength of the Yun family could not stagnate.

In this way, the population under the Yun family was increasing rapidly, and by the winter of the fourth year of Tiancheng, the total population under the Yun family had exceeded 2.3 million.

Note 1: As early as the Western Zhou Dynasty, the term "well-off" appeared. In the "Book of Songs", there is a sentence in "Daya Minlao" that "the people also work, and they can be well-off". Here, well-off means a more stable life.
