The Northern Song Dynasty was different from the Ming and Qing dynasties. There were few people and many lands. It was logical that food and clothing were absolutely fine. In fact, it was not the case. Due to the powerful land annexation, wealthy and powerful families had annexed all the good land, and ordinary people only had rotten land, slopes, and wasteland. The wealthy families planted good land but paid not much tax, and ordinary farmers who planted wasteland and rotten land paid a lot of taxes, which created a poverty situation for ordinary farmers. The emergence of sweet potatoes changed this situation.

County Magistrate Su said: "Erlang, how many seedlings can be produced next year? I want to promote them in the whole county. By then, Yanggu County will be the richest county in the world."

Wu Song smiled and said, "Mr. Su is dedicated to serving the people. The idea is good, but the summer potatoes that can be planted are only 1,000 acres. The growth period of summer plants is short and the yield is low. It is expected that one acre will produce only 4,000 kilograms. Four thousand kilograms can only use seedlings for 100 acres next year. That is, what can be developed next year is 1,000 acres times 100 acres. At most, Chao Baozheng from Jeju has already booked 3,000 acres of sweet potato seedlings, which can be used for no more than 50,000 acres of seedlings sold to Yanggu County. Master Su is only suitable for helping to promote this matter, and cannot be forced, otherwise the people will be disgusted."

The Magistrate Su nodded: "I am anxious. All officials from Yanggu County, all the officials in Yanggu County will cooperate with the promotion of sweet potatoes, but the price of Erlang seedlings should not be set too high."

Wu Song said: "Don't worry, the price is very generous. A minimum of 6,000 seedlings per mu are sold for only 100 cents of cash. If you are on credit, you need 200 kilograms of sweet potatoes or 400 kilograms of dried sweet potato seedlings."

County Magistrate Su said: "The price is not low, but it is still worth it to produce 7,000 or 8,000 kilograms per mu."

The harvest of sweet potatoes is completely explosive in Qinghe and Yanggu. Farmers of all sizes come to visit. They are tired of accounting and accounting for several days in a row. The rich farmers nearby ordered sweet potato seedlings for the spring of next year with full payment, and some spent dozens of cents to buy some roasted sweet potatoes to eat.

Zhujiazhuang, Hujiazhuang, Lijiazhuang, Dongxi Village, and dozens of nearby rural areas, ordered more than 50,000 acres of seedlings. What's more, farmers in other places are waiting with money, and farmers who have no money want to sell for credit.

When news is published on the business information paper, more people come. In the past few years, those who can understand the newspaper are all scholars or wealthy families, and it is very common for hundreds of acres.

Jia Simin was worried at the box full of copper coins and complained to Wu Song: "Brother, after selling so many copper coins, just counting money, it would be a big project."

Wu Song said: "Don't be proud of it. This is mainly your credit. When you finish your work, you will be rewarded with a box of copper coins."

Jia Simin whispered: "Brother, you can also keep the seeds of spring sweet potatoes. Choose small spring sweet potatoes to keep the seeds, and plant them the same next year. In this way, it will be enough to promote 300,000 acres of sweet potatoes, and the entire Dongping Mansion will be enough."

Wu Song said: "Or what if you are only suitable for agriculture, not for business. If you have revealed the bottom line, will you still be in a hurry to buy it? Besides, what if all the sell-offs come and you cannot refuse a relationship? "

Cotton seeds were also sold at a good price. In contrast, since corn was sown late, it had not been harvested, and the amount was too small, Wu Song did not intend to promote it. In addition to seeds, there were tens of thousands of big geese raised in spring and fat ducks also began to enter the top dressing stage, as well as fish farming in rice fields, fish farming in cages in water pools, etc. The income in agriculture is not a small amount. The warehouses in Wujiazhuang and Xiaowujiazhuang were almost filled with instantly, and there were a lot of copper coins and silver in the underground silver warehouse. The grain warehouse was full of sorghum, soybeans, and millet.

Wu Song was immersed in the joy of harvest, Jiao Ting came and held a letter.

"Brother, the letter from the shipbuilding manager Su," said Jiao Ting.

Wu Song opened it and saw that it was very happy that thirty sea vehicles had already been launched, and 400 craftsmen had been busy for several months and had a good grade.

Su Jiang, the general manager of Dongping Mansion Shipyard, was also a little excited. Although the shipbuilding workshop was known as the four hundred craftsmen, there were actually only one hundred skilled craftsmen, and the other three hundred were just new men. In three months, they gradually improved their work efficiency.

When Wu Song, Wu Yong, Gongsun Sheng, Hu Sanniang and others arrived, they saw a huge sea carriage on the river. Gongsun Sheng said: "What a big ship, my brother is really a big deal."

Wu Song said: "Looking at it is because it is in the river. When the boat reaches the sea, you will find that it is smaller. It is only forty-five meters long and five meters wide. It is a small sea boat."

Navigation was nothing small, so Wu Yong hired craftsmen from other shipyards to conduct quality inspections, which was also to make up for the craftsmen of his own shipyard. In the era when there were no advanced instruments, it took several days to detect so many ships.

In addition to twenty-four commercial ships, there are six of these thirty sea vehicles. The bows and sterns of these thirty sea vehicles have been specially renovated. The cannons cannot be installed. The cannons must be installed after the ship arrives at Qinghe Island.

After inspection, the ship's quality is very good.

Wu Song patted Su Jiang on the shoulder and said, "I did a good job and I gave bonuses. From craftsmen to small workers' apprentices, you can set a specific system."

The craftsmen next to him were very happy to hear that it was not easy to work these days, and those who could get their salary smoothly were all good bosses, and there were bonuses here, which was really up to the right person.

Su Jiangdao: "The existing wood is enough to build thirty sea vehicles and ships. Do you need to continue building them?"

Wu Song nodded: "Craftsmen, please pay attention to the rest of the car. First build twenty sea vehicles and ships, leave some wood for later use, and wait for me to contact the seller of the wood."

A few days later, thirty sea crafts and ships arrived at the Bohai Sea along the Yellow River. Eight merchant ships were delivered to Chai Jin's family, eight Hu Cheng's family, and the remaining eight were from Wu Song's own caravans, and the other six were warships. The fleet arrived at Qinghe Island. The craftsmen in the artillery workshop installed artillery under the leadership of Liu Yingxing. The bow of the ship was a two thousand kilogram gun with a long barrel and a long shot. The solid shells could be fired for five miles. They were known as General Weiyuan's running. The two 1,000-kilogram guns were installed on both sides of the ship. Although there were few cannons, they had far exceeded the firepower standards of this era.

Ruan Xiaoqi was in charge of the First Fleet. Now there are more than 70 merchant ships. Eight warships are equipped with a large number of long snake cannons and giant crossbows. Because the ship is small, it cannot be equipped with large general cannons.

The first fleet traveled to the Jin Kingdom, sailed in Liao Kingdom, transported tea, silk, cloth, vegetables, fruits, porcelain, etc. From the Jin Kingdom, Liao Kingdom, transported fur, cattle, horse, ginseng, etc. On average, every half a month, Ruan Xiaoqi and more than 300 sailors under him were in a row and were very busy. They escorted the fleet and the cattle and horse trade had become a pillar industry of Tongda Big Cars.

Please give me a monthly vote, please recommend votes, and have a wave of support. Thank you, brothers.
