Wu Qiang's face changed suddenly, and he couldn't help but imagine that Chen Qiliang might have tempted or coerced Yu Qingyan in this way, and Yu Qingyan probably had such a tangled situation at that time, his heart ached, and he turned around and left.

When Yu Qingyan saw Wu Qiang's performance like this, he knew that he had a misunderstanding, and it was too late to get up and chase after him.

Xiao Caizhi didn't notice Wu Qiang when he turned his back, and when he saw that Yu Qingyan's expression was abnormal, he asked with concern, "What's wrong?" ”

"Nothing." Yu Qingyan is calm on the surface, but he is bitter inside.

"Then what does Miss Yu think of everything I just said?"

Yu Qingyan hesitated, gritted his teeth and said, "Okay or not, how about giving you an answer next time?" ”

"Okay, well, then I'll wait for Miss Yu's good news." Xiao Caizhi's mood couldn't help but be excited, and he felt that he had great hope.

Originally, Wu Qiang had a good mood because of the recovery from his injury, but after visiting Yu Qingyan, all his good mood disappeared.

Especially when Xiao Cai used the conditions of revenge to lure or coerce Yu Qingyan again, she would still hesitate, could it be that eating a hundred beans was still not fishy? has already had a painful lesson, but she is still obsessed, which makes Wu Qiang extremely angry, and at the same time feels that she is completely incorrigible for revenge, and his heart is dead.

Puguang and others did not have long eyes, but came to touch this mold, the food in Jiaoshan Shui Village in the past two days is too unappetizing, it is because of the comparison that they found out how beautiful the life of Puyuan Temple is.

At the instigation of Ling Yuqiang and other teenagers, Puguang came to Wu Qiang to discuss opening a small stove, but was scolded by Wu Qiang, under the pretext that now is the time to take refuge, and the impact is too bad.

Although what Wu Qiang said had a sense of venting, it was not unreasonable, and Puguang and the others immediately covered their faces and ran away.

But two days later, when Puguang and the others felt that only by returning to Puyuan Temple could they have a chance to improve the food, Wu Qiang came over and claimed that they could do it once, although Puguang and the others didn't know why Wu Qiang's attitude turned 180 degrees, but they were still very happy.

This is because when Wu Qiang's body was about to return to normal, his good mood was destroyed again. Ling Xiuzhu came to tell him that Yu Qingyan had agreed to Xiao Cai's family affairs, and it had already spread in the Jiaoshan Shui Village, but he was still kept in the dark, so he was naturally very angry.

If it weren't for the fact that the limelight is tight now, Wu Qiang would have taken Puguang and others to leave Jiaoshan Shan Village, and he would have ended up out of sight. But he didn't do anything at all, and it wasn't his character, and in the end he decided to use the method of opening a small stove to vent his inner anger.

There are a lot of fishing tools and equipment in Jiaoshan Water Village, Gu Jixuan and other people from the Tiandi Association have not been less tooth sacrifices after coming to Jiaoshan Water Village, and they are not surprised that Puguang and others came to borrow fishing gear, and they are very enthusiastic to send people to help.

It's just that Wu Qiang was disappointed to find that not only was it difficult to supply grain, oil and non-staple food in Jiaoshan Shui Village, but even some condiments were very lacking, which could only meet his standard of improving his food once, and the back kitchen of Jiaoshan Shan Zhai was basically swept away by him.

What makes him even more intolerable is the huge Jiaoshan Shan Zhai, which does not even have a little green salt, it is all some inferior salt that is yellow and has many impurities, and it is difficult to insist on using the whole village for half a month with such salt.

Anyway, there was help from the people in Jiaoshan Zhaizhai for fishing, and Wu Qiang finally took some inferior salt back to his residence and called Ling Xiuzhu, and Jiang Fang also followed by when he saw it. What is he doing here? Of course, I want to purify the salt.

In the history of China, the salt industry has a strong cultural color, and the development of China's salt industry also has a tortuous and undulating process. According to relevant historical records, the Ming Dynasty inherited the monopoly of salt and iron since the Western Han Dynasty, and the state implemented a monopoly operation on the salt industry.

During the Hongwu period of the Ming Dynasty, in order to solve the problem of insufficient military salaries for the garrison in the north, the Ming Dynasty followed the practice of the Song Dynasty and formulated the policy of "summoning merchants to transport grain and salt with them", that is, the open middle system, allowing private individuals to exchange grain and grass for salt (also known as salt banknotes, which are a kind of voucher for taking salt, which can be circulated as tokens) and engage in salt trade.

The specific method is that the merchants transport the grain to the border granary, and the government receives the grain and distributes the salt to the merchants for salt trafficking, and the merchants can use the salt to go to the designated salt works to withdraw the salt, and then sell it in the designated area to obtain profits.

Salt is also the oldest commodity in China. In ancient times, in the Spring and Autumn Period, the pipe said: Ten people eat salt for a family of ten. A family of five, salt for five people. Unsalted, starved and swollen. Behind the huge profits of the salt industry, it is full of the bitterness and blood and tears of the people.

The technology of salt purification is very simple, nothing more than a few steps: dissolution, filtration, detoxification, evaporation and crystallization, etc. If it is produced in large quantities, it is more complicated, requiring tools such as hammers, iron drills, sieves for making salt, linen, charcoal, wooden barrels, iron pots, and even hand-cranked stone mills. And Wu Qiang only needs to purify a small amount of salt for use, so it doesn't have to be so complicated.

Wu Qiang checked it, and all the necessary tools were ready, so he used a hammer to crush the salt into a fine form as much as possible, and then poured the salt powder into a wooden barrel and stirred with water, so that the salt fully melted into the water, and waited until all the salt was dissolved.

Wu Qiang then poured the solution into another wooden barrel covered with a double layer of cotton cloth, and soon a lot of gray-black scum appeared on the cotton cloth. Remove the cotton cloth, the color of the solution in the barrel has become lighter, but there are still a lot of impurities, and a double layer of cotton cloth is covered on a wooden barrel, and after filtering it again, the color of the solution left is lighter.

Seeing that the second daughter was looking at all this with a little cuteness, Wu Qiang explained to them by the way: "This is called filtration, no matter how many times it is filtered, it must be until the color of the solution becomes this light color before the filtration is completed." ”

Ling Xiuzhu was smarter, so he asked, "Brother Wu, as you said, can you start purifying now?" ”

Wu Qiang explained: "The amount we need is small, and this salt is obtained by drying, and it can be regarded as a primary detoxification, oh, that is, to remove the poison, if it is a directly mined salt, it cannot be evaporated and purified at this time, but should continue to carry out the detoxification stage." ”

Jiang Fang's eyes widened, and she said in surprise: "Oh my God, it turns out that there is still poison in the salt?" ”

Wu Qiang comforted: "Don't worry so much, as long as you go through the process of poison analysis, there will be nothing at all." ”

"Since Brother Wu said that it was okay, then it must be fine." Ling Xiuzhu's blind trust in Wu Qiang can be described as blind.

Watching the solution churning and bubbling in the pot, although Wu Qiang was full of confidence on the surface, he was also a little apprehensive in his heart, after all, he had talked about this knowledge in junior high school chemistry, but he didn't know whether he could do it.
