: Boiling the salt

Wang Daocheng was wandering around the streets, and saw that although the city in Hangzhou was still a bit depressed, the pedestrians on the road were very busy, and many buildings burned by the war were repaired. Surprisingly, there were not many cities that had just experienced the war and often sold themselves as slaves and soldiers looted everywhere. From time to time, there were fully armed soldiers passing by, and even more neatly bribed. Seeing this, Wang Daocheng couldn't help but secretly called himself a stranger. In the turbulent Tang Dynasty, there were many martial artists who could command troops to fight, but often these people could attack but not manage them. Under the rule, the people often lived in poverty. Often, once the troops weakened, the counties under their jurisdiction would expel their appointed guards, change their flags and surrender to the enemy, and their power would collapse.

Wang Daocheng was walking for a while and felt a little tired. He was about to return to the inn to rest, but he saw the crowds in front of him, as if something strange was happening. He felt strange, so he quickly walked forward, but saw the onlookers covering their noses with their hands, their faces full of sarcasm. Wang Daocheng was strange, but he saw four or five donkey carts coming not far away. Seeing that the cart drivers were dressed in Hangzhou Prefecture, the strange thing was that the donkey carts were approaching, but he felt a stinking scent coming to his nose. He hurriedly covered his nose and was curious about what was on the cart. He saw more than a dozen children following the cart, shouting without any trace: "The poor man on the Huai River, no room for storage, and the yellow and white stinky thing is taken home to hide."

The man in the convoy was annoyed and raised his whistle to beat him. The children fled in laughter. Wang Daocheng was guessing, but he heard someone laughing and laughing: "The new arrival of Lu Zhan is very strange. He just arrived, but he actually asked the county under his jurisdiction to pay the old man in the cesspool pigpen regularly. He is a third-rank high-ranking official and does not farm and accumulate fertilizer. What's the use of these? It's really ridiculous."

When Wang Daocheng heard the words of others, he recalled the notice he saw at the city gate. His curiosity became more and more intense. He bought two cakes from the pancake stall on the side of the road. While eating the cake, he followed the donkey cart. The donkey cart dug old soil from several residents' cesspools along the way, and finally drove into a Lifang near the south of the city. It was close to the gap opened when the Huzhou army broke the city. The war was the most intense. The buildings in the yard were almost burned into a piece of white land. After the city was broken, Lu Fang saw that it was close to the south gate, and the Zhejiang Wharf was not far away. The transportation was very convenient, so he migrated all the remaining residents here, setting up the armor workshop, equipment workshop and future firearm workshop in Moye Capital, and preparing to build iron plants, gun factories, and shipyards along Zhejiang in the future, and turn it into its own military base.

Wang Daosheng saw that the convoy entered the gate of the fang gate, and there were soldiers guarding him at the door. He couldn't get in. He was helpless and was about to go back to the inn first, but he saw four or five big cars coming from behind. Judging from the smell, he was also loading dirt. He had an idea and dragged his feet back. The driver didn't pay attention and jumped into the car and hurried in a basket full of dirt. When the convoy entered the door, the guard guard at the gate hated the smell of the car and did not check the car in detail. He just cleared the driver's waist sign and put them in. After Wang Daocheng entered the fang, he observed the outside through the gap in the car, and saw that the fang was busy.

In the scene, the craftsmen were building a house shed. He found an opportunity to jump out of the car, pressed the hat on his head lower, mixed in with the small workers, transporting soil and rocks, but his eyes were staring at the convoys that carried dirt. The convoys all rushed to a bamboo shed where they had built. A man was holding a short wooden stick in his hand, followed by more than 30 people. He thought he was the leader here, saying something loudly, and he thought he was instructing his subordinates to do things. Wang Daosheng believed that there were many people working, and no one around paid attention to him, so he carried a piece of wood from the ground, walked to the bamboo shed, and pricked up his ears to listen to the man's voice.

"After you arrive at each village, just like this, put the sand into the cow pens, pig pens, and toilets of each family, find a cool wall, mix the sand, stove ash and human and animal manure, and pile it loosely. Pay attention, it must be a cool place without sunlight." The man raised his voice and pointed to a layer of white crystals on the manure pile next to him and said, "Nitrification can be produced everywhere. Then you will take out the white soil and bring it back. Do you understand?"

Seeing everyone behind him nodding, the man nodded with satisfaction, and asked everyone to repeat the key points he had just said. He squatted down and took some surface nigra from the mound of dung on the left, put it into a skin bag, came to a stove next to the bamboo shed, and began to explain it again and again;

"First of all, before you boil the nitride, you must first determine whether the nitride soil has been made. There are two ways to judge, one is to taste it." The man took out some soil from his skin and put it on his left palm, took a little and put it in his mouth. The muscles on his face immediately twisted. Obviously, the taste of the soil was very bad, so he spit it out in one mouthful and said, "If it tastes bitter, salty, and spicy, it will be done. If it is particularly spicy, it will be the best nitride soil." Speaking of this, the man stretched out his left palm towards everyone, and the people took a little and put it in their mouths, and spit it out again, and his face became very ugly.

"There is another way to identify it." The man used a short stick in his hand to pull out a little charcoal on fire from under the stove, took a small handful of the sting from the nitrate soil on his palm, rubbed it finely and sprinkled it on the charcoal. A spark immediately burst out, and everyone immediately exclaimed a burst of awe.

"If Mars can be exploded, it is the best-quality nitro earth." The man explained. Wang Daocheng had already thrown the wood aside and mixed into the crowd. The people were so focused that they did not find that there was one more person around him. Wang Daocheng was fascinated by hearing it. Although he didn't know what the nitro earth mentioned by the man was, he could actually produce such things from the dirt. There was indeed a very knowledgeable person around Lu Fang, and it was no wonder that he could break Hangzhou in three days.

The man who explained said that he seemed to be a little tired. He whispered to the young man closest to him, and the young man left quickly. Wang Daocheng then realized that the sword was inlaid with gold ornaments on the waist of the boy who left. He had been doing business for many years and had extraordinary vision. Although he had just glanced at him, he had already judged that the sword was of great value and could be matched with such weapons. This young man was afraid that the position of the man he guarded was not low. Thinking of this, Wang Daocheng was in conflict with his heart. He wanted to find an opportunity to leave without leaving any trace, but he felt that he had not yet figured out the specific use of this nitrile soil. If he lost this opportunity, he was afraid that it would be more difficult to climb to the sky. While he was hesitating, the boy had returned, carrying two gourds in his hand. The man drank two sips of water and continued to point at the stove.

The objects on it were explained while demonstrating: "These are wood ash made from buckwheat stems. If there is no dry buckwheat, wheat straw is fine. First, crush the nitroso and wood ash and mix them into the pottery basin, mix them at a weight ratio of about 7:1, then pour in hot water, and pour over the ash soil. Then pour in cold water. After the pottery basin is full, pour the muddy water into the basin next to it. This is done in total three to four times, throw away the remaining residue in the basin, put a new mixture of wood ash and nitroso in the basin, heat the previous filtrate, then pour it into the basin, and then rinse it with clean water, three to four times, and finally retain the filtrate and pour out the filter residue." After the demonstration, although the man had the help of the boy beside him, he was already sweating profusely. He pointed to the filtrate he obtained and asked everyone, "Do you understand?"

Everyone said in unison: "I understand."

The man nodded and said, "Okay, you will give me a demonstration and show it to me. In the future, you can teach the village chiefs of various places to do it without having to do it yourself. However, this is not fake, so you must master it."

Everyone came forward to demonstrate one by one. The man was very patient. If something was wrong, he would explain carefully one by one, without any boredom. Wang Daocheng in the crowd was panicked. The man had explained carefully before, and everyone listened carefully, but no one noticed him. But now everyone took turns to demonstrate, and he decided to be unable to get through, so he wanted to squeeze out outside. But in order to figure it out, he stood in the crowd before he knew it. He wanted to squeeze out without any alarm. Seeing that more and more people were over, Wang Daocheng couldn't help but become more anxious. He couldn't help but spread his arms, pushed others away, and squeezed out outside.

Seeing that more than ten people who had demonstrated did a good job, Lu Fang couldn't help but nodded with satisfaction. After he captured Hangzhou, he knew that he was no different from a traitor in Yang Xingmi's heart. If he wanted to survive, he had to strengthen his strength and connect foreign players, so that he would not dare to attack him. So he planned to install firearms in his army as soon as possible. He believed that as long as Mo Ye had two thousand to two thousand five hundred mature mesh rope guns, he would accidentally put them into use in the defense war, and he could give a heavy blow to the Huainan army and let Yang Xingmi retreat. At that time, Yang Xingmi was already in his twilight years. As long as he died and his son had no great achievements to subdue the generals, Mo Ye could expand to the southeast and sit on the Huainan army.

The storm is here. Since charcoal, among the three main components of black gunpowder, sulfur is very easy to obtain in ancient China, but natural saltpeter is almost no output, and imitation is not too difficult. In order to prevent the rest of the forces from being far superior to their own vassal states, Lu Ban decided to imitate ancient Britain first in his territory, establish a factory for producing earth-nourishing and purification, and store a large amount of saltpeter, so that even if the other party can make firearms, it will not be able to play a role due to the lack of sufficient ammunition. In order to achieve this goal, he selected more than 20 loyal, reliable, intelligent and capable people from the children of the craftsmen, and personally explained and demonstrated to them with the honor of the third-rank high-ranking officials. It can be seen that their good intentions are obvious.

Lu Fangzheng was proud, but saw a man in the crowd squeezing out. He couldn't help but be stunned. He heard Zisheng standing behind him shouting: "Well, that man, stop, which group are you from."
