The whole family sat together for dinner, and everyone at the table was discussing the matter of tonight's deal. Su Ren said a lot to Su Ming, he is the person in charge of the transaction tonight, and many things must be handed over to him personally.

After eating, the two sisters-in-law cleaned up the table and took the children to sleep, and the eldest brother took out two white cloth bags from the wooden cabinet in the upper room, and the cloth bags were not big enough to contain the green salt they were going to trade tonight.

By the middle of the evening, it was already completely dark. Su Ming and Su Zhe came to the gate of the courtyard with a salt bag, at this time four carriages came from behind the fort, and there were people sitting on each carriage, Su Ming looked at a total of six people, all of whom were neighbors who practiced with him in the morning, he and his thirteenth brother put salt on a carriage, and the carriage slowly drove towards the gate of Erweibao.

The gates of the Second Castle were quietly opened, and four carriages lit torches into the night. Su Ming and Su Zhe's carriage walked in the middle, and the two of them were driven by iron pillars.

"Eighth master, you don't have to worry too much, the Li family has a lot of power in Songjiang Mansion, and it has a good relationship with the officials and masters in Jinshanwei Town, we will trade on the 14th of every month, and I have participated in it seven or eight times this year, so there will be no problems." Tie Zhu saw that Su Ming's eyes had been carefully staring ahead, and said to him.

"It's better to be careful, this time our trading volume is much larger than in previous months, and we can't afford to have an accident!" Su Ming reminded.

The content of this transaction was actually finalized by both parties last month. Su Ming also knew that they could trade directly after meeting and inspecting the goods later, they were already very familiar with the Li family, and they still had credibility with each other.

The carriage traveled about ten miles to the west, and when it came to the trading place, Su Ming sat on the carriage and waited, the time they agreed on was Hai Shi, and the other party would appear in a quarter of an hour.

Su Ming sat in the car and waited quietly, paying attention to the movements around him. Time passed slowly, but the Li family team that should have appeared still did not appear.

"What's the matter, it's all in the middle of this, why hasn't anyone from the Li family come yet?" Su Zhe saw that the Li family's convoy had not appeared, and he began to be a little anxious.

"Don't worry, wait, maybe there was an accident on the road." Su Ming comforted everyone.

But when he waited until the time, it was already late at night, and the Li family's convoy still hadn't come, and Su Ming already understood what was going on.

He has been in the Shen family for a year and a half, how can he not know the relationship between the Shen family in Shanghai County and the Li family in Songjiang City, the Li family was able to gain a foothold in Songjiang Mansion, but with the help of the Shen family, and the Li family also followed the Shen family to smuggle at sea, so that there is everything today.

Now that he has left the Shen family, he didn't expect that the Li family would cut off contact with Erweibao. The Shen family is going to destroy Erweibao! After cutting off the grain of Erweibao, Weizhuang had only one way to go.

Back in the fort, Su Ren saw that Su Ming had not completed the transaction and came back empty, and he had already guessed what the reason was just by looking at his brother's eyes.

"If the Li family doesn't trade with us, they think they can trap me Erweibao to death? It's a big deal, let's find a new buyer! Su Zhe sat in the living room, watched the three brothers bow their heads and said loudly.

But how can it be so simple to find new buyers, what they need is food, food for hundreds of people, the ability to send food, and not alarm Jinshanwei Town, there are not many in the entire Songjiang Mansion.

Moreover, the Li family does not send grain to Erweibao, if the Shen family wants to deliberately suppress it, who would dare to trade with Erweibao.

"It's all my fault..."As soon as Su Ming spoke, he was interrupted by Su Ren.

"What do you say, the Li family doesn't want to trade, let's just find a way, tomorrow I will go to the town to see Lord Qianhu, if he doesn't pay him again, we will go and ask to see the commander!" Su Ren said solemnly.

"You can't go, even if you see the commander, he won't necessarily be able to speak to us, this thousand households are obviously targeting us, and it's useless to go." Su Ming said.

"No, we will sell the salt to Suzhou Mansion, no one in Suzhou Mansion will know us, and then we will buy grain and we will transport it back, that is, take a little more time, the price that Suzhou Mansion can give will definitely be higher than that of the Li family." Su Qingping said.

The Li family only gave 50 wen for a pound of green salt, and the market price of green salt was 120 wen for a catty, although it could be more expensive to sell it in Suzhou City, but from Suzhou to Erweibao more than 300 miles, it took them at least ten days to drive a carriage back and forth.

"It's better to go to Suzhou City than to go to Hangzhou City, Suzhou Mansion is close to Shanghai County, and the Shen family has a relationship with many merchants in Suzhou City... Although Hangzhou City is farther away and takes more time, Hangzhou City is more prosperous than Suzhou Prefecture, and the price of green salt will be higher, and no one will recognize us. Su Zhe said at this time.

Su Zhe obviously already knew that the Li family had broken off the deal with Erweibao and might have something to do with the Shen family, so he proposed to go to Hangzhou.

"I also think it's good to go to Hangzhou, let's go over quickly, and then take a boat back, and the time it takes may be much shorter than Suzhou." Su Ming said.

"Then go to Hangzhou, this time you go with the fifth child, let's not expect too much, just buy back 50 stone of grain, if you can't buy it back, at most half a month, most of the people in Weizhuang will run out of food." Su Ren said.

One pound of coarse grain is only enough for an adult to eat a day, and there are nearly 100 households in Weizhuang, with a population of about 600, and 50 stone is barely enough for the people in the institute to last for a month.

"Since we have gone to Hangzhou, we plan to come back by water, so we can buy more food. I still have a lot of money here, and I will buy food together when the time comes! Su Ming thought that he couldn't use the money at home, so he said.

"If you have money, I still have some here, fifth brother, you can keep the money yourself, and I will give you another 5 taels of silver when you go, this hired boat may not be cheap to come back, you must be careful." Su Ren said.

The imperial court forbade the sea and forbade any ships to sail on the sea, and the Ming naval division would often patrol the East China Sea area, and all the ships were destroyed and all the people were arrested and killed.

Therefore, it is far more dangerous to buy food from Hangzhou City than Su Ming said, but now they have no choice.

The four brothers were discussing a series of going to Hangzhou to buy grain, although they did not go to Hangzhou many times, but they also had a relationship to find out where to find ships to go to sea, from Hangzhou to their salt factory, it was only three or four days away.

"Big brother!" Su Ming seemed to think of something, and suddenly looked at Su Ren and said.

"How?"

"I suddenly thought of a way to improve the quality of green salt." There are likely to be a lot of accidents when they go out this time, but their brothers have never relied on sea ships to make a deal, and if one of them is not caught correctly, it is likely to be a catastrophe.

"What's the solution?" Su Ren asked curiously.

"I saw it in an ancient book of the Shen family, I'll try it tomorrow, if I can, we should be able to sell this salt for a lot more money!" Su Ming said.

Su Ren also knew that his younger brother was smart, and Erweibao had been a talent for many years. To transport the grain back by sea from Hangzhou, I am afraid that the money needed will not be less, and his own five taels of silver may not be enough, but he has this money left in his hand.

"Okay, then tomorrow you hurry up, you must buy back the grain in half a month at the latest, we still have more than six stones of grain at home, tomorrow I will ask people to send a little grain to the families who have run out of food." Su Ren thought for a while and said, tomorrow I will go to the liaison office of the Li family in Jinshanwei Town to ask what the Li family means.

Su Ming couldn't sleep for a long time at night, he didn't expect that because he would bring so much trouble to Erweibao, or that Erweibao's troubles started from the moment his father died, but he postponed the danger for a year and a half!

When he woke up the next day, Su Ming did not go to the morning exercise with his eldest brother and fifth brother, but began to prepare for the purification of green salt with his thirteenth brother Su Zhe, he asked Su Zhe to pour all the green salt into a water tank and melt it with water, and pick up firewood in the firewood room in the yard by himself.

"Do you need me to call a few more people? Your fifth brother is going to patrol the fort wall today! I'll be out later. Su Ren and Su Qingping finished their morning exercises, and when they came back, they saw that Su Ming had melted all the green salt, and came to him and said.

"Go ahead and get your hands dirty! Later, I'll ask the thirteenth brother to call the iron pillar over, and the three of us will be enough!" Big brother, be careful on the way out! Su Ming said to the eldest brother.

The fifth brother wants to go to the fort wall to patrol today, but this matter must not be sloppy. The eldest brother left, and Tiezhu quickly came over to help.

Su Ming built a fire in the courtyard of his house, and the fire burned very high, so he asked Su Zhe and Tie Zhu to carry a large vat out of the house with him and put it on top of two stools.

"You two go and clean some sand, half coarse and half fine sand, about half of this vat." Su Ming said to the two.

Su Zhe went to wash the sand, Su Ming took out a knife and began to dig a hole in the bottom cloth of the large tank, but you have to be very careful to open a hole in the tank, if you are too anxious, the tank may break.

It took an hour, Su Ming finally dug the hole, at this time the firewood in the yard had burned almost, Su Ming hit six buckets of water to extinguish the fire, and then he continued to dig a hole under the water tank, and when the hole could enter a finger, he took a bamboo pipe and inserted it just right, and then took out the bamboo pipe and wrapped the bamboo pipe with a coarse cloth on one side, and inserted it into the water tank hole to fix it.

At this time, Su Zhe and Tie Zhu washed almost the same sand, Su Ming spread a layer of sand in the jar, and then broke the burned charcoal and washed it and put it in a layer, after spreading two layers of gauze, pour another layer of sand, put a layer of charcoal, a total of five layers and when all the sand and charcoal are used up, the cylinder is already full of 7 points.

"Starling, this thing can make salt better?" Su Zhe looked at the things they had wasted half a day of hard work and came out, and Bu understood what these charcoal and sand could do.

"You first pour some clean water into the tank, rinse the charcoal slag, and be sure to wait for the water left by the bamboo pipe to become clear." Su Ming ignored Su Zhe's inquiry, this charcoal should be enough.

The water was poured into the vat, and it took a few minutes for Su Ming to see water flowing out of the bamboo pipe. A lot of charcoal could be seen in the water flowing out, and Su Ming continued to pour the water until the water flowing out of the bamboo tube began to become clear, and he asked Su Zhe and Tiezhu to stop.

When the bamboo pipe of the water tank stopped flowing, Su Ming and the two of them poured the melted salt water into the large tank, and slowly the bamboo pipe began to flow liquid, and Su Ming used a wooden bucket to catch it underneath.

"Eighth Master, isn't this the same as our salt field filtration? The salt pan is made of six layers of cloth, which is placed in a large vat with sand and charcoal in between.

Our six-layer filtration of this green salt has reached the limit, and it is useless to filter it again! Tie Zhu saw that what Su Ming was doing was similar to the salt water filtration in the salt field, so he couldn't help but remind.

"If it's useless, I'll know later, thirteenth brother, you take these brine out, take it to the kitchen and cook it, be careful not to stain the brine water." Su Ming watched as the salt water was poured into the bucket, and a bucket of salt water had already come out of the bamboo pipe under the large vat, so he asked Su Zhe to boil the salt.
