Chapter 164: Cooperation Reached, Salt Production

Zhang Shi nodded. After thinking for a moment, he felt that these three people could be used. He then took off his mask and showed his true face.

"Ah, it's Mr. Zhang Shi!"

Cheng Xiaobai recognized Zhang Shi at once and almost screamed with excitement. Zhu Dachang's hanging heart was finally relieved. After all, in their minds, Zhang Shi's image had always been modest and friendly. of.

Wang Wu also took a long breath and joked.

"Brother Zhang Shi, it turns out you are making fun of us. If I had known it was you, we wouldn't be so panicked."

Zhang Shi smiled and looked at the three people who were completely relaxed. He took out some food and water from his backpack and handed them to them.

"We are all old acquaintances, just kidding. From now on, you can use my port as a resting place. There is no shortage of anything on the island. If you need supplies, you can directly contact the person in charge."

Wang Wu was also moved, took another look at the island, and then made a suggestion to Zhang Shi.

"To be honest, our freight business has just started, but it is extremely popular. There are countless people coming and going every day. Boss Zhang Shi, if you build a maritime station here, you should be able to make a fortune."

Before Wang Wu could finish speaking, Zhu Dachang interrupted in a deep voice.

"There is some risk. The people we receive are a mixed bag of people. Maybe one day we will get caught up with the hostile forces of Mr. Zhang Shi. When the coordinates of the island are exposed, it will be a troublesome thing."

Zhang Shi smiled hoarsely, glanced at the surrounding fleet, then waved his hand and said.

"This station is a good idea. I will work hard to implement it. When the time comes, I will ask you to help me promote it more. The benefits will be indispensable to you. As for Brother Zhu's concerns, just relax. No one dares to act wild like me."

The three of them looked at each other and saw that the principal had no objection, so they nodded in agreement, which was regarded as a verbal cooperation.

At this time, Zhao Feng also got on the boat, listened to the conversation of several people, looked at Wang Wu and the others, and asked doubtfully: "You guys are doing a really good business, but I have a question, there are only three of you, so Aren’t you afraid of meeting someone with evil intentions?”

Zhu Dachang pointed at Wang Wu and smiled.

"Hehe, it's not like I haven't encountered anyone who is not smart, but I have been dealt with by Brother Wang. If you want to eat this bowl of rice, how can you do it without some fists and kicks?"

Cheng Xiaobai also added.

"Our team actually has more than three people. The other people are busy with other things at the base camp. Today we are taking on a cargo transportation job, so only three of us are dispatched."

Zhang Shi and the three of them added each other as friends and then sent the three of them away.

Zhang Shi had actually had the idea of ​​a post station in his mind for a long time, but he put it aside temporarily because he was worried that the current survivors lacked purchasing power and lacked transportation channels. Unexpectedly, it was such a coincidence that he met Wang Wu's team today. Zhang Shi followed the trend and reached a cooperation with them, starting a travel agency. After all, no one would have too much money.

"Brother Feng, I'll leave the inn to you. The location will be next to the port."

Zhao Feng raised a thumbs up and responded decisively.

"Don't worry, leave it to me!"

After that, he went to the research center to gather a team of craftsmen and mobilized a batch of resources to inspect the terrain and draw the design drawings.

It would take some time for the news of the station to spread, and they still had a lot of time to make preparations. Zhang Shi was not in a hurry, but was anxious about another thing. Their salt reserves were running low.

The number of people on the island has exceeded the one thousand mark. After Zhang Shi controlled the number of people to this number, he did not continue to recruit. On the one hand, there were too many people and a lot of supplies were consumed. On the other hand, the management was also a problem. Trouble.

Zhang Shi got a sea salt extractor during yesterday's check-in, which can steadily extract a small amount of salt every day, but the amount of salt is only enough for a small number of people.

Zhang Shi remembered that a person’s daily salt intake requirement is about 6g, and the requirement for a thousand people is 6kg. The current price of salt in the trading market has been quite exaggerated. Even a wealthy survivor like Zhang Shi was unwilling to be taken advantage of, so Zhang Shi started thinking about making salt again.

Zhang Shi recalled the knowledge about extracting salt in his mind, and found that it all came from short videos or literary works, and he didn't know whether it was reliable or not. He first led people to dig a large pit on the shore, then filled the pit with linen and introduced seawater. Afterwards, the seawater was evaporated through sunlight and heating, and some white crystals naturally precipitated, forming the coarse salt consumed by ancient people.

Zhang Shi took out a small piece of crystal and tasted it. It was indeed salt, but it was a little bitter, probably because there were many impurities in it.

After thinking for a moment, Zhang Shi added several screens and linen cloth to the water inlet of the salt pit, and also added some charcoal to effectively filter out most impurities.

The salt produced this time was obviously whiter and the particles were smaller. Zhang Shi tasted it and found that although it still had a slight bitter taste, it no longer affected the consumption.

Ge Dalong was attracted by the movement on his side, and when he saw him making salt, he also followed suit and made suggestions.

Zhang Shi was originally satisfied with the initial improved salt production results, but after listening to Ge Dalong's explanation, he realized that this was far from the best solution.

In order to obtain table salt with higher purity and better taste, further purification process is required. Therefore, the two decided to use the existing resources on the island to try to build a more complete salt production system.

First, they organized craftsmen to build a series of small evaporation pools on the seashore. These pools are divided into primary evaporation pools, secondary evaporation pools and refining pools according to size and function. The primary evaporation pool is used to evaporate seawater initially to reduce the water content; the secondary evaporation pool further concentrates the salt and increases the saturation of the brine; and the refining pool uses more sophisticated control to allow the brine to slowly crystallize under specific conditions in order to obtain higher quality salt.

In order to improve the purity of the salt, Ge Dalong also instructed the craftsmen to lay a thin layer of fine sand and gypsum in the refining pool. These substances are byproducts of the mining area and can absorb some impurities. At the same time, they promote the orderly growth of salt crystals, making the final salt particles more uniform and delicate.

As for deeper filtration and optimization, it is impossible to carry out under the current conditions, but with only these few processes, the purity of the salt has increased significantly. At least in terms of taste, it is not much different from the salt produced by the sea salt extractor.

Having solved the big problem of salt, Zhang Shi was in a good mood. With the stable development of the salt-making industry, the island has gained another economic development route, and the subsequent sale of salt is also a way to make money.
