The general carrying capacity of the No. 2 Fu ship on the route of the Ming Dynasty is between 200 and 350 tons, and the displacement of the old lock ship used by Huang Han for trade is also similar to that of the No. 2 Fu ship.

It is rare to be able to carry more than 400 tons of goods, and with a load of about 200 tons, it is worth 2,300 stone of polished rice, and 400 tons is 4,600 stones.

Even if the difference in the price of one stone of polished rice is as high as one tael of silver, this business cannot be done, and the gross profit of only two or three thousand taels of silver after a trip to the sea trade is not enough to buy money for Zheng Zhilong, wouldn't he have to lose money?

Moreover, the loss, the unloading capacity after arriving at the port, and the freight from the port to the Beijing division for sales are not a small amount.

There is no strong backstage for selling grain, and you have to spend money to make a point up and down, because if you don't take off the hat of smuggling and entrainment, you may be seized and prosecuted by the government at any time.

Huanghan is not afraid of who will check the entrainment of large-scale grain transportation, Liaohai is now the Lushun Kou Camp is the only one, and there is no need to care too much about the cost of transportation, because a large number of products are sold to the Wa State, among which porcelain and iron are relatively cumbersome, and too much tonnage is required for transportation.

When returning to the ship, the purchase of copper ingots, lead, sulfur, saltpeter and other resources of the Japanese country cannot meet the excess capacity of the fleet, so the transportation cost can not be calculated by bringing milled rice back.

In this era, wind power is used, which is a power that can be used for free, and there is no future generation of ships that will consume more diesel and increase transportation costs.

100 barrel granaries have been built close to the port of Huxue City, and new grain depots are being built in Jinzhou, Lushunkou, Wolf's Nest, Ningyuan, and Juehua Island, and no less than 100 cylindrical granaries will be delivered this year.

Each silo can store more than 5,000 stone of grain, such a new type of storage can better reduce the loss, from the bottom of the grain to make the grain storage period more than double.

The construction of these grain depots is close to the seaport, and there are carts for Lifu to use free of charge when they are short, so as not to carry sacks to transport grain over too long distances and reduce work efficiency.

The money for warehousing is not low, but it can still be afforded, after all, it provides a well-paid job for the strong laborers who have no technology and only a brute force.

Therefore, Huang Han's grain will not lose money and will be able to win social benefits, which is not the main thing, but because Daming has an extra stone of grain, at least he can save a Han person.

In fact, in the most difficult time, it is possible that one stone of rice can make ten pots of porridge so that a thousand people will not die the next day.

A strong man facing starvation can survive with two bowls of porridge to save his life, maybe in the future, he will be able to contribute more than 25 stone of grain every year with the 50 acres of land allocated by the "Red Banner Army", and how many Han people can be saved by these grains?

Doing everything possible to bring food back is one of Huang Han's main purposes, and he is already calculating the capacity. The unit of measurement of trade between countries is very important, and the volume unit of stone is converted into one stone of polished rice in the Ming Dynasty of one hundred and fifty-three pounds of the Ming Dynasty, which is converted into ninety-two kilograms in later generations.

The Tokugawa family was able to raise 250,000 ishigU rice in 23,000 tons, and it would take 100 fortune ships with a cargo tonnage of more than 200 tons to transport the grain.

The copper ingots bought for 300,000 taels of silver are 5.1 million catties, reaching about 3,000 and 30 tons, and more than 140 merchant ships and warships have thrown down the ballast stones and replaced them with copper ingots, because it is normal for the weight of the ballast stones on a ship to be more than ten or twenty tons.

With the addition of 7,000 or 8,000 tons of tonnage of sulfur, saltpeter, lead, pickled fish, dried scallops, etc., which were purchased for 150,000 taels of silver, all the ships that came to Edo Castle had nearly ninety percent of the space.

This time, because of the pressure to put pressure on the Japanese state, they deliberately came to Edo Bay to show off their might, so they had to run a third more by sea, and it took at least half a month to go back and forth.

In the future, it was possible to trade with the trade representative appointed by Tokugawa Iemitsu in Nagasaki, and the price had already been fixed in the Edo Agreement, and the two sides only had to deliver the quantity and inspect the quality.

When the fleet returned to the Nine Ghosts' private port, Wang Yuqi and the others had already made all the preparations, and everyone worked together, and it only took one day to empty this pirate town, and all the valuable things were brought with them, and the 170 ships returning to the sea should be overloaded by about 10%.

On the way back, all the ships had a deep draft, which affected the speed of the ships, so they kept their speed at less than four knots.

Huang Han did not continue to rob the ships he encountered, because he saw such a large fleet from a distance, and the armed merchant ships he encountered set sail and fled early.

It was much more difficult to catch up with them and complete the robbery, so Huang Han chose to escort the fleet home.

After resupplying and resting for a day at the port of Jeonra Province in Korea, the fleet continued its voyage, and after more than 80 days of sailing, it finally arrived at the port of Tiger Cave on July 12.

There are two people who have been waiting here for ten days, and they are so anxious that they are about to have a heart attack, these two people are Sun Yuanhua's eldest son He Ding and his second son Sun He Dou, and Xu Laifu, the confidant and housekeeper of the pavilion elder Xu Guangqi, accompanied by him.

Huang Yizhou and Huang Han, the two chief military officers, shouldered heavy responsibilities, and the men and horses were deployed on the front line against Jiannu, and in the case of the imperial court's extreme distrust of the Guan Ning army headed by Zu Dashou, the "Red Flag Army" was undoubtedly the Dinghai Shenpin.

Therefore, when the Denglai rebellion was raging, the military department did not consider transferring the "Red Banner Army" to help at all.

The important ministers of the imperial court and the emperor jointly adopted the strategy of drawing salaries from the bottom of the kettle to deal with Zu Dashou, and now there are six or seven thousand Guanning troops in Shandong fighting fiercely against the rebels of Li Jiucheng and Kong Youde.

The main generals are Zu Dabi, Wu Xiang, Zu Kuan, Wu Sangui, etc., and the old generals of the Guanning Army who were forced away by Huang Han from Ningyuan, such as Jin Guochen and He Weizhong, all took their families to fight for military exploits in Denglai.

To tell the truth, the rebellion of Li Jiucheng and Kong Youde was really not a plot and then moved, even they didn't know that it would set off such a big wave, and they couldn't imagine that Dengzhou, which had the most artillery fire from the Ming Dynasty and had Portuguese mercenaries, could be easily taken.

With this big city and strong city as a base, and with unparalleled artillery fire, Li Jiucheng and Kong Youde and other anti-bone boys have new ideas.

At this time, because Li Jiucheng, the initiator of the rebellion, must take the lead in every battle, he was loved by the rebel army, and was elected as the generalissimo by everyone, and Kong Youde could only be condescended to the deputy marshal.

They were ready to establish themselves as kings and establish a separatist force, in order to increase their popularity, they hoped to get the support of civilian officials, so Li Jiucheng and Kong Youde repeatedly persuaded Sun Yuanhua, who committed suicide when the city was broken, to join the rebel camp.

Sun Yuanhua's lack of leadership skills does not mean that he is a soft bone, his answer is very simple: "Only one death!" ”

Li Jiucheng and Kong Youde and other old generals of Dongjiang Town were often scolded when they saw Sun Yuanhua, but they all couldn't help it, because in good conscience, Sun Yuanhua was indeed not thin on them.
