With the strong support of the Badaohe area, they have been very smooth in developing the Yidaohe area. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Their standardized ports and equipment have not yet been equipped, and the people have already moved into plank wooden houses.

Liu Qianxing's younger brother, Liu Gang, and other businessmen who had contracted the sulphur ore also took a swordfish boat and quickly went upstream to investigate the location of the sulphur mine.

Zhang Guoan could have pointed out more to them, but when they think about it, in terms of their productivity, they can't use it at all, and this one mining area is enough for them to work for a while.

Zhang Guoan observed the sulfur kiln they had built at the mouth of a river, and felt very interesting, it was almost the same as the world on that side.

Because this sulfur was used in the real life of the Great Song Dynasty, it was really very widely used, and the people of the Great Song Dynasty did not have modern atomic chemical theories and methods, but they would also use distillation methods to purify.

Their craftsmen quickly erected two large burial mound kilns, and then connected the tops of the two kilns with ceramic pipes.

A large iron pot is placed in one kiln with a stove on the stove, and the other is a separate ceramic vat.

The craftsmen heat the raw sulfur in the form of mud from the vicinity of the volcano, wait for the sulfur to melt, filter out the unmelted material, continue to heat it, and stir it constantly to vaporize some of the impurities.

Finally, when the sulfur boils, the sulfur gas will automatically go down the ceramic pipeline to another kiln, and the sulfur gas will be cooled down in this process, and it can be solidified in the ceramic cylinder to obtain purer sulfur.

At that time, Zhang Guoan pointed to the ceramic pipe and said: "If the sulfur solidifies inside and blocks the pipeline, what will you do?" ”

This is exactly what Zhang Guoan was worried about, so he just used the torment method. Rely on a thermometer to deal with it.

The craftsman smiled and said, "It's so simple, and if you break it, you get the best sulfur!" ”

“------”

The craftsman smiled and said, "How much money is the pottery pipe?!" ”

Well, Zhang Guoan was speechless, this is indeed really simple, but he thinks it is complicated.

The name of the Great Song dye merchant was Yu Lian.

Zhang Guoan instructed his craftsmen to build a conjoined kiln. This makes it possible to roast and retort at the same time, making full use of the heat source.

Then he handed over the sodium sulfide and potassium nitrate that were transported at the same time, and explained the method to that Yu Lian.

Yu Lian had always been curious about what that sodium sulfide was, he had never seen it!

He was about to grasp it with his hands, and he might even want to taste it with his mouth.

Zhang Guoan stopped his movements!

This sodium sulfide is a strong alkali that can cause burns when it touches the skin and hair, and if you can endure the burns and eat it, it will decompose hydrogen sulfide in the gastrointestinal tract and cause hydrogen sulfide poisoning.

Yu Lian asked curiously, "What is this thing?" ”

Mr. Zhang did not call it by his real name. said directly: "It's called stinky alkali, use it carefully, it will hurt people's skin." ”

Yu Lian remembered it at once, because there was really some smell.

Zhang Guoan said: "There is no such thing in the Great Song Dynasty, but I used the scientific formation method to refine the first batch of stinky alkali and nitrate -----, and I will not charge for it. From the second batch, it is necessary to start counting money. ”

Sulfur dyes can only be used as a reducing agent with sodium sulfide liquid. Otherwise, it can't be printed and dyed at all.

It is impossible for Zhang Guoan to give him a thermometer and a watch, so after writing him a prescription, let him try to make it with a craftsman little by little.

The standard pier was finally built.

Zhang Guoan looked around, and felt that this was what it looked like.

He saw a total of six people manipulating the manpower tower crane, and they lifted a dozen baskets of raw sulfur at once, turning the boom with a creaking sound. Wobbly sent to the sea boat.

The sailors on the ship pulled down the tray and quickly removed it.

At this point, the boom is pulled back and loaded again.

Deputy Captain Guo Beyu led the Liuqiu guards and stationed them in a few wooden houses on the edge of the dock.

He said to Zhang Guoan, who was watching the loading of the crane, "Master Zhang, I will arrange personnel on the dock to count the number of goods they have shipped out." Make sure to receive one percent. ”

Zhang Guoan laughed, armed customs?

"Yes, the security of this river and its surroundings is under your control, everything is just like in the Badaohe area!"

"Yes, Master Zhang! ------But what if someone else comes to sell here? ”

Hehe, this kid thinks really far, and it's far from that time.

"The same is also a harvest of goods, or the same money."

"What if there are pirates?"

Zhang Guoan nodded, this is really possible, it is better to build a castle here.

Zhang Guoan said: "Fight with all your might!" If you find that you can't beat it, lead everyone to the mountains! Nothing is as important as your life! ”

Deputy Captain Guo Beyu nodded on the surface, but said in his heart, I have acacia wood cannons, arquebuses, and crossbows, so I'm very afraid!

The so-called cannon crossbow is a bag of explosives on the crossbow rod, and after lighting the fuse, it is launched, and if it pierces the hull of the ship, it is also a terrible thing.

This was not made by Zhang Guoan, but was figured out by twenty and a half children.

This allows the bed crossbow, a backward weapon, to maintain and develop on the Great Island of Liuqiu.

When everything was on track, something happened again.

They were robbed of their sulphur mines in the mountains!

According to the miners who ran back, about 100 indigenous people appeared out of nowhere and robbed them of their labor tools and household items.

The miner also said: "Before, they just stole it, and we didn't care, but who knew that later they actually ganged up to rob it, but fortunately there were no dead people." ”

Zhang Guoan nodded, fortunately you ran fast.

He said, "Why didn't you come and report it to the Stream Guards when it was stolen?" ”

"----- small ones think a few pieces of clothing are nothing."

Zhang Guoan said in a deep voice: "What they stole is not clothes, it is the law of the island that I beg!" ”

Zhang Guoan originally wanted to lead the team to deal with it personally, but when he saw Deputy Captain Guo Beyu eagerly trying beside him, he said: "Captain Guo Beyu, you take the Liuqiu Guards on a trip, and this kind of illegal thing must be punished!" ”

Deputy Captain Guo Beyu immediately straightened his chest and raised his belly, and shouted: "Yes, Master Zhang's family!" ”

The 110 heavily armed members of the Liuqiu Guards jumped onto the five swordfish boats and rowed quickly towards the mining area upstream.

This is a real actual battle, and it is not a sambar hunt, and more importantly, without Master Zhang's family watching from the sidelines, they can do whatever they want.

Team member Wang Zheng said: "Captain Guo, this time I want to teach them a lesson!" Hit hard! ”

Team member Zhang Depei said: "No------ catch them and let them work!" ”

Deputy Captain Guo Beyu said: "They are all stupid and stupid people like deer pigs, what kind of work can they do? ”

Team member Wang Zheng said: "That's it, that's it!" ”

Team member Zhang Depei protested and said: "Master Zhang's family said that people are useful!" What Master Zhang's family said! ”

mentioned the words of Master Zhang's family, and no one in the crowd argued anymore.

Zhang Guoan watched the heavily armed 110 people rowing the swordfish boat quickly, and soon disappeared at the bend of a river, and suddenly felt a little worried in his heart, is it a little anxious to let it out alone now? !

He couldn't help but clench the micro rush in his hand. (To be continued.) )
