Let's take Zhang Juzheng as an example, the dignified generation of ministers only dares to make some fuss about the number of fields, and he has never touched the salt tax! As for the price of grain, he can only regulate it through market means and suppress it within a certain range, leaving huge profit margins for those who meddle in grain! As for the salt, he didn't move! You can see how great the power of these people is!

And the rumor of Liu Haojia's construction of a salt factory has already spread, but they have not taken any action. This shows that in their opinion, Liu Haojia is insignificant at all! They feel that Liu Haojia has no channels, and there are not enough manpower, and the market has been exhausted by them, even if they can't sell the salt, maybe this salt factory will end up in their hands!

But they didn't expect that Liu Haojia's breakthrough point was not in the private market at all, but in the army of the nine sides! As long as he opens up this market, he has enough power to encroach on other markets!

On this very day, the saltworks by the sea were full of dense crowds! There is also a gong and drum team to make the drum music loud! It turns out that today is the day when the salt works officially started!

When the time was almost up, Liu Haojia finally walked to a high place surrounded by everyone. He had just taken people around again and made sure that the salt works could start working normally.

At this time, Zhang Zhi stepped forward and bowed down and said, "Master Hou, the time has come, do you think we should start now?"

Liu Haojia nodded and said, "Then let's start!"

According to the rules, it is natural to worship God before starting work. Especially on the seaside, there are more worships on the gods of the sea. So in the sound of gongs and drums, Liu Haojia was in front, Zhang Zhi was behind, and the others followed to deliver sacrifices.

Then after a series of complicated processes, the worship ended, and then Zhang Zhi handed over a red flag to Liu Haojia. Liu Haojia, who was standing on a high place, waved the red flag in his hand vigorously, and the sound of answering immediately sounded not far away, and at the same time, more people waved the red flag to indicate that the gate could be opened and the water released!

After receiving the order, the salt workers who had been prepared for a long time shook the floodgates vigorously! At this time, it is the time of high tide, and the sea water is hula-la-la-la, and it pours into the filter pool!

The height of these salt pans is not consistent, the first layer of salt pans is also relatively high, the second layer is relatively low, and the third layer is the lowest, and the area is also the largest. And then it's all about elevating layer by layer! The reason for this arrangement is to use the principle of drop to let the seawater pass through the filter tank to filter out most of the impurities.

The first level of the filter pond is a large area of pebbles. These pebbles can directly intercept large chunks of seagrass and other things. The second layer of filtration is made up of fine sand that has been washed repeatedly. Once the seawater has passed, smaller impurities are filtered out!

The floodgates opened, and waves of water poured into the purification pool, quickly passing through the cobblestones. Some of the grass and seaweeds floating in the seawater, and even small fish and shrimp are blocked out by the pebbles. Then the much clearer water flowed to the second purification pool, and the water filtered by the sand was really clear, and there was not a trace of debris! Then the clear water flowed into the salt pans!

The sight in front of them amazed the officials and gentry standing next to the salt pan, and they all said that Wu Ninghou was ingenious, and this method was used!

The third layer of salt pans is the lowest, and at the same time the largest salt pans. The filtered seawater is air-dried here, concentrated into brine, and pumped by a waterwheel to the highest salt pans. The brine will be filtered there for a third time.

The third time the filter pool was not pebbles and sand, but smashed charcoal! Charcoal can absorb impurities that can not be blocked by fine sand, and the filtered brine is as clear as well water without impurities, and the salt particles from such brine are small, the color is pure, and the taste is not fishy or astringent, which is the real top grade!

Soon the salt pans were filled with seawater, and the salt workers dropped the floodgates to completely cut off the seawater, and then a large number of salt workers rushed up to replace the pebbles and fine sand in the filter tank. The pebbles and fine sand will be washed again and replaced the next time the salt pan gates are opened.

At this time, Zhang Zhi had already run to the side of the salt pan with the corner of his robe and scooped up a bowl of seawater. He walked up to Liu Haojia with seawater and handed it over, and said at the same time, "Master Hou, the filtration method you said really worked! You see, the water is crystal clear and very transparent!"

Liu Haojia looked down and haired

The water in the bowl was indeed extremely clear, so he nodded and said, "Let's ask the master to take a look."

Zhang Zhi turned around and beckoned to the crowd, and three old salt workers came out of the crowd. These three old salt workers are probably the first time to see such a powerful person as Wu Ninghou, and in just a dozen steps, they took two steps forward and one step back, and finally walked in front of Liu Haojia!

When they had just finished kowtowing and were hesitating whether to get up, the leader was dragged over by the impatient Zhang Zhi, and said, "Come, how are you going to see this sea?"

As soon as they saw the seawater, the eyes of the three old salt workers lit up! They gathered around and looked at the white porcelain bowl in Zhang Zhi's hand. Seeing that the water in the bowl was rippling and free of impurities, one of the old salt workers couldn't help but nod and say, "Good water! There really is no clutter!"

The other nodded and said, "Indeed, this method of filtering is really wonderful!"

The last old saltman stretched out his finger and dipped it in the seawater and wiped it in his mouth, and then he said, "The salty taste has not changed, but the fishy smell has faded a lot, what is the truth in this?"

The old salt worker who spoke first said, "Didn't Master Hou say that he still had to use charcoal to filter? Maybe by then, there won't even be a little bit of fishy smell!"

The three old salt workers discussed it like this, forgetting that Zhang Zhi was still in front of them. Zhang Zhi also knew that these old craftsmen were like this, but they were always very selfless when it came to craftsmanship, so he simply turned his head to Liu Haojia and said, "Master Hou, it seems that these old salt workers say that this water is good, and it should be able to produce good salt!" Look at the book

Liu Haojia also heard the discussion of the old salt workers, nodded and said, "In this case, I will wait for the brine to come back, and then let the salt workers distinguish the color, and then wait for the salt to come out!"

Hearing this, Zhang Zhi arched his hand and said, "In that case, the slave and maid send the Hou Ye! But the slave and maid will not leave the salt factory, and the slave and maid want to stare at it."

Liu Haojia said, "Since this is the case, you should work hard!"

Then Liu Haojia explained a few words to the others and turned to leave. Because he had other things to deal with, the hired men of the salt works. Because this year's project is over, it is a pity that these trained people are let go in vain, so Liu Haojia is ready to leave some people.
