Early the next morning, Fu Tianqi and Cheng Xuefeng took twenty capable soldiers to find Lu An.

Without saying a word, Lu An took twenty people to the cave and taught them the process of making salt by hand.

Last night, he told Cheng Fu and the others that he wanted them to find some suitable people to come over and learn how to make salt.

As for what is "suitable", it is naturally up to Fu Tianqi and Cheng Xuefeng to define it.

After all, this is related to the livelihood of more than 500 people in the future, and the people they are looking for must be the most trustworthy group of people.

"Brother Fu, Brother Cheng, you must warn your brothers and sisters that all the snowflake salt that flows out of us here is purchased from the Western Regions!"

"This is crucial!"

"After all, our Central Plains has always been very strict in controlling the sale of salt, and if the secret of our salt production here is revealed, it will be difficult to make money."

"Therefore, I will find someone to specialize in the snowflake salt sold to the Central Plains, and it is only supplied in small quantities, only to some rich families."

"Most of the rest will be shipped to the Western Regions by Mifflin and Bachier."

Fu Tianqi was puzzled, "Brother Lu'an, since this is the case, why don't we directly take local materials in the Western Regions, make salt on the spot, and sell it directly?" ”

"Yes, wouldn't it be extra to bring rock salt from the Western Regions and then make snowflake salt and transport it back to the Western Regions?"

Lu An shook his head and smiled, "If that's the case, it's easy to spread the method of making snowflake salt, and then if you want to make a profit from snowflake salt, it's not so easy." ”

The three of them had just said this, and someone was outside asking to see them.

"Ma Liu, what's the matter?" Fu Tianqi pointed to the dirty hands of the soldiers who came in with a disgusted expression, "What did you kid do, make your hands like this?" ”

Ma Liu glanced at Lu An aggrievedly, "It was Mr. Lu who asked for ......."

Lu An smiled slightly, "How is it, it's done?" ”

"Hmm." Ma Liu nodded, "The brothers have been smashing in the vat for a long time, but it's too dirty, otherwise, Mr. Lu will go over and take a look?" ”

"Okay, let's go over together."

The three of them followed Ma Liu to the outside of a cave, more than 20 soldiers were bare-chested and bare-chested, tired and sweaty, and when they saw Fu Tianqi and Cheng Xuefeng also coming, they hurriedly got up.

"Mr. Lu, take a look, isn't that so?"

Ma Liu asked, pointing to a large vat.

Lu An and the three of them walked to the vat, looking at the messy and black things inside, Fu Tianqi frowned and asked, "Brother Lu An, this is ......?"

"Hehe, that's a good thing!" Lu An glanced at it, smiled mysteriously, and said to Mamen, "Just do it like this, smash all the wild chrysanthemum grass roots like this, then add water to the tank and stir, and finally filter out the grass roots and other impurities with a net, leaving only the black thing to dry." ”

Ma Liu blinked and looked at Fu Tianqi again.

"Didn't you hear Brother Lu An's words?" Cheng Xuefeng glared, "If the brothers want to live a good life, they will listen to Brother Lu An in the future!" ”

"Yes!" Ma Liu, as well as the soldiers around him, hurriedly answered and continued to work.

Fu Tianqi glanced back at the soldiers, and smiled, "This method is good, just use it as a training soldier." ”

"yes, usually these guys cry when they come to training, but now it's okay, and they're tired and sweaty when they do some work."

When Lu An heard this, he was instantly speechless.

He didn't mean to torture the soldiers.

"The two eldest brothers, the wild chrysanthemum grass juice that Ma Liu smashed out is a rare good thing!"

"Oh?" Fu Tianqi and the others showed curious expressions again.

The surprise brought to them by snowflake salt is enough to convince them, so what kind of wild chrysanthemum grass root smashes out of the juice is sticky and black, what else can it do except use it as glue?

Lu An didn't explain too much, "Brother Fu, do you have any sulfur here?" ”

"Brimstone?" The two shook their heads at the same time, "Except for some things that can be bought in the pharmacy, it is usually difficult to get them, I don't know how much my brother plans to use?" ”

Lu An was also embarrassed.

In order to make a finished product from natural rubber, the most important thing is sulfur.

Otherwise, the things produced will soon be deformed in summer or when exposed to heat, and only after sulfur fumigation can its ductility and fixity be guaranteed.

"A lot!"

Lu An only said these two words.

Cheng Xuefeng slapped his thigh, "It's done!" Tianqi, I'll take people to Jincheng County right now and rob their armory! ”

Sulfur is a military substance, extremely flammable, except for a small amount in the pharmacy, but also only in some large cities of the garrison army, and the control is extremely strict.

Lu An didn't expect that Cheng Xuefeng would actually move Jincheng County because of his sentence.

Jincheng County is a border city of the Great Xia Kingdom, mainly guarding against the Bailanqiang people in the west.

However, over the years, the Bailanqiang people in the west have never dared to attack the border of the powerful Great Xia Kingdom, so the city defense force of Jincheng County is actually very easy.

Fu Tianqi hesitated and shook his head, "No, Xuefeng, Jincheng County is too close to us, in case it is found, I am afraid that our place will never think about peace again."

If you want to go, go to Subtown! ”

Zicheng, more than 100 miles away from Jincheng County, is much smaller than Jincheng County, and the city defense force is also a lot weaker.

Lu An only wanted to get the sulfur, and as for how to get it, it was not his concern.

"Brother Fu, Brother Cheng, if it's convenient, get twenty or thirty catties of sulfur back first, it's enough to use it for a while.

Later, when Mifflin and Bachell return, I'll let them find a way to buy some in the Western Regions. ”

Those two Western Regions giants have a lot of knowledge and many ways, so they must have a way to get sulfur.

With sulfur, it's much easier to make a variety of finished products out of natural rubber.

After deciding down, Cheng Xuefeng immediately took a hundred brothers, put on some makeup, and set off for Zicheng.

Two days later, Cheng Xuefeng came back smoothly and handed over the nearly fifty catties of sulfur he had stolen to Lu An.

At the same time, the rough products of natural rubber were also formed into black bumps more than a foot square by Ma Liu's outside the cave.

If it weren't for the cold weather, these unprocessed natural rubbers would have been melted by the sun.

Lu An also found some carpenters among the soldiers, made some molds respectively, and asked people to put a piece of natural rubber rough product in a pot to continue boiling.

During the boiling process, a little sulfur is added.

An hour later, under the astonished gaze of everyone, Lu An smeared the melted natural rubber onto the molds that had been made.

"Brother Fu, Brother Cheng, look, how is this saddle?"

Lu An personally took off the rubber saddle that had been molded and put it in front of the two of them.

"Saddle?" Fu Tianqi took the saddle and checked it with his hand, "It's so light!" ”

"Not just light, but ...... It's much more comfortable to sit on than our saddle! Cheng Xuefeng pressed the rubber saddle and was pleasantly surprised.

Ma Liu peeled off another mold, "General Fu, look, this is a wooden barrel!" ”

"No, it shouldn't be called a wooden barrel, it should be a plastic barrel!"

Fu Tianqi was still reluctantly admiring the rubber saddle in his hand, and looked at the rubber bucket in Ma Liu's hand again, his eyes brightened.

"Haha, Brother Lu An is right, this black thing is no worse than snowflake salt!

In the future, we can use this thing to make plastic buckets and saddles to sell, and we can also make a fortune! ”

Hearing this, Lu An shook his head secretly.

Saddle?

Plastic buckets?

It's a tyrannical thing!
