Chapter 2 I am Zhang Jiusi ()

There were stars all over the sky, and the dark night sky seemed so quiet, with only a horse lantern on the bow of the boat, revealing a dim red light.

Zhang Yang sat at the bow of the boat, kicking his legs constantly. The just-ignited fire of hope fell into this endless darkness again.

Why am I so unlucky?

Fate, why did you make such a big joke with yourself!

A few days ago, I was a graduate student in the Army Academy's light weapons design and manufacturing major, and took a boat to a secret arsenal in Hainan.

This arsenal mainly produces the latest type of assault rifle. This time I went there and worked on the production line for a month, so I could sit in the office to carry out research and development comfortably. What satisfies me the most is that the salary and bonus are good. After working for a year, I will be given a house of more than 200 square meters.

However, as I fell into the sea, everything turned into bubbles. I was a landslide. After drinking a few sips of sea water, I lost consciousness.

He was caught up again and was surprised to find that he had actually arrived in the Yuan Dynasty and the 12th year of Zhizheng in Emperor Shun of Yuan Dynasty.

He became a salt transporter in a salt farm. In this Jiangnan water town, he took various waterways to transport salt to various places.

He is called Zhang Shicheng and Zhang Jiusi, and his three younger brothers are named Shiyi, Shide and Shixin, and is also called Jiuwu, Jiu6, and Jiu7 respectively. The names of the Yuan Dynasty are really interesting.

Zhang Jiusi was his official name. In this Yuan Dynasty, where racial discrimination was particularly serious, the lowest was the so-called Southerners, namely the Han people and other tribesmen in the Southern Song Dynasty ruled by him. He was a Southerner and did not deserve a name. Adding the age of his parents was his own name Jiusi, and the name Shicheng was called privately.

Zhang Shicheng? He must not be a big shot. Otherwise, why have you never seen this person in history class? However, the person you see the most in history class is Duke Zhou.

How great would it be if he became Zhu Baba when he came up. Then he changed his name to Zhu Yuanzhang, who was the founding emperor of the Ming Dynasty.

Since he came, it would be better to die than to live. But when he returned to Zhang Shicheng's house, his heart was completely cold.

Several thatched houses, the adobe walls have been mottled and fallen off, and they look scarred. The only door is pieced together with a few broken wooden boards, and air leaks everywhere. Can people live here?

Zhang Shicheng is just a small salt transporter, and his salary of several hundred kilometers a month is just enough to starve.

However, what people have in this era do not have is knowledge. They grew up in elementary school, junior high school, high school, university, internship. They grew up in the 21st century and started learning from the age of three or four. The knowledge accumulated over hundreds of years is their greatest wealth. What's more, the majors they learned in college can come in handy.

Once upon a time, I personally made a rifle in the internship workshop.

Red Turban Army? Are you making trouble? Zhu Yuanzhang? Are you uprising? Yuan Dynasty? Are you surviving. Since you have arrived in the Yuan Dynasty, let me make a big contribution!

The first step is naturally to accumulate capital. No matter what you do, you must have money and food. Jiangnan has been a land of fish and rice since ancient times, so there is no need to worry about food. Therefore, the first step is to make money.

Anyway, it is also a salt transporter. While transporting salt to the court, he transports some of his own salt to sell. Wouldn't this solve the problem?

However, transporting private salt by yourself is illegal after all, and you have to behead your head. Moreover, transporting ordinary sea salt will make the profit too small.

Therefore, I purified the coarse salt by myself by using chemical methods. This is an experiment I have done in junior high school, so I am naturally familiar with it.

Coarse salt, that is, sea salt. The sea salt obtained by evaporating the sea water directly contains various insoluble impurities such as sediment and sand, as well as several soluble impurities.

First dissolve the coarse salt into water, then filter to remove insoluble impurities, and then evaporate, you will get pure salt. "Brother Shicheng."

Zhang Yang was thinking, and a voice interrupted his thoughts.

Zhang Yang looked up and saw that it was Li Bosheng, and he was Zhang Shicheng's best friend.

"Bosheng, didn't you rest in the cabin?" Zhang Yang asked.

"I can't sleep." Li Bosheng said. "Brother Shicheng, we're so successful this time. When we go home this time, we finally don't have to worry about the rice jar being empty. I bought fifty kilograms of rice, which is enough to eat for a while."

"Don't worry, we don't have to worry about rice jars in the future." Zhang Yang said.

"By the way, how did you find soda ash?" Zhang Yang asked.

A few days ago, the coarse salt was purified. After several dissolution, filtration and evaporation, the salt obtained was not white and there were impurities inside. Zhang Yang knew that this impurity could be dissolved into water. Filtration could only filter out impurities such as insoluble silt and sand. These things had to be added to produce chemical reactions to remove them.

The scientific name of this reagent is sodium carbonate. It is impossible to find sodium carbonate from a place nearly 700 years ago. Fortunately, Zhang Yang also knows its common name, namely alkali, also called soda, and is used for steaming buns.

"Ste, where is our soda ash?" Zhang Yang asked.

"Sodium ash? What?" asked Shit.

Zhang Yang looked at the stunned brothers and suddenly remembered: Hou's alkaline method.

In this era, there was no industry that synthesized soda ash. The only soda ash comes from natural stear ore. The price is very high and ordinary people cannot afford it.

A good-looking woman was unable to cook without rice. Zhang Yang looked at the yellow sea salt in the pot and was a little anxious.

"Brother, someone knocked on the door outside." said the fourth brother Shixin.

It is illegal to boil salt privately, let alone purify the coarse salt. Therefore, the four brothers chose to work at night, so no one paid attention to the smoke coming out of the wood when heating.

But on this night, someone actually knocked on their door.

"Open the door." Zhang Yang said, holding the only kitchen knife in the house tightly. If the official is a lie, he will give it his best.

Under the dim oil lamp, a familiar face came in.

"Brother Bo Sheng!" Shi Xin recognized it.

He is from Hailing, Taizhou. He moved here a few years ago. Over the years, he and his brother Shixin were already friends of life and death. He rescued Shi Yi, who fell into an ice hole in the frozen river.

Li Bosheng walked in swagger, not knowing how nervous his arrival had brought to these people.

"Huh? What are you cooking? Can you eat it?" Li Bosheng stretched out his little finger and put it in the pot and dipped it.

"Bah! It's so salty!" Li Bosheng said.

It must be salt so salt, but this salt looks much cleaner than sea salt.

"We are purifying coarse salt," it seems that we can't hide it. Anyway, Li Bosheng is also a person who can trust it.

Li Bosheng really doesn't understand the modern word "purification?"

"It is to process the coarse salt and turn it into fine salt." Zhang Yang said.

"Make tricks? I like it." Li Bosheng said, "But it doesn't seem to be considered salty, it's so yellow."

"I still lack a material," said Zhang Yang.

"soda ash."

"There is no soda ash, but there is no mouth alkali." Li Bosheng said.

"Yes, that's it." Zhang Yang said. He remembered that when he was in chemistry class, the teacher said that there was another other name for soda ash called oral alkali.

"Okay, I have it at home, I'll take it for you." As he said that, he walked out again, muttering as he walked: "Anyway, there's no need now."

Dissolve the oral alkali in brine and stir with a wooden stick. After a while, yellow crystals appear from the pot.

Success! Zhang Yang was secretly happy.

The impurities were filtered again and the moisture was evaporated. This time, pure white powdery refined salt finally appeared.

The purified dozens of kilograms of fine salt are indeed a hot item. This time they were sold out. Zhang Yang remembered the soda ash again. How could Li Bosheng know about this kind of thing?

"Because, before I came to our salt field, I was a warlock." Li Bosheng said.

"Soter? Isn't that the alchemy refiner?" Zhang Yang asked.

"Yes, I have a few refined Yin-Yang Complement Pills here. After taking it, I will do the couple's affairs again, and make life more and more prosperous." Li Bosheng said as he pulled it into his arms.

"Forget it, I don't have a wife yet." Zhang Yang said.

Warlock? Zhang Yang was shocked and suddenly thought of something.

"Then can you find sulfur, saltpeter, and charcoal?" Zhang Yang asked.

"Of course, sulfur and saltpeter are available in the pharmacy, and charcoal can be burned by itself."

“What if I need a lot?”

"How many?"

“The more, the better.”
