Sister Han is good at farming

"What can happen? Don't worry, Old Fu! We are not trying to suck the blood and sweat of the people. We are just trying to take some money out of it to buy charcoal for the winter!" Yuan Pingzhang shook his fan indifferently.

Their calculations were very clear, and they did incur a lot of "losses" when they first collected tax grain.

The common people dare not speak out but are angry.

But on the third day of collecting tax grain, they were dumbfounded.

"What did you say? You are here to supervise us collecting grain taxes under the order of Lord Zhou?"

Fu Yuanhao looked at the visitor with an unhappy expression.

"Yes! This is Lord Zhou's handwriting. If you don't believe it, you can take a look!" The man took out Zhou Zheng's seal in a dignified manner.

After seeing this, Yuan Pingzhang and others looked at each other in bewilderment.

"Did Zhou Zheng plant some spy among us? Otherwise, how could he know our plan so quickly?" Wang Sibo asked Yuan Pingzhang with his eyes.

Yuan Pingzhang was also puzzled.

"But we are the only ones who know about this plan?"

He was stunned when he said this, and suddenly looked at Fu Yuanhao. "You were the one who told the secret?"

Fu Yuanhao shook his robe and said, "How much free time do I have? Is it worth it for me to go to him and complain about such a small matter?"

"If it's not you, then who is it?"

The problem comes back again.

"I suggest that we all take care of the grain tax issue first. Otherwise, we may not have the chance to find the culprit in the future?" Wang Sibo consoled everyone in a soft voice.

"Well, what Lao Wang said makes sense. If the grain tax issue is not handled properly, Zhou Zheng will be indifferent to us."

Zhangqiu Ming also said.

"If we don't handle this well, it's not just Zhou Zheng who will be irritated with us. General Ling and his men at Xiyu Pass will probably ride over here on their horses at night and tear us all to pieces!"

Shen Zhizui rolled his eyes.

"I just feel unwilling to accept this! If I find out who is behind this, I will destroy him!" Yuan Pingzhang snorted coldly with frosty eyes.

Ruan Qingqing, who was the one behind the scenes coming up with the idea, was completely unaware of this. She was currently discussing the charcoal burning issue with Old Man Ruan and others.

"Master, I heard that several charcoal-burning families near the capital have run into trouble. The charcoal supply this year is more limited than in previous years. If we take over the charcoal-burning work, we can make a lot of money."

Mr. Ruan shook his head pessimistically.

"It's not an easy task to take over! The first problem that stands in our way is that the charcoal we burn produces smoke. The charcoal burned by the rich is smokeless and odorless. We can't sell our charcoal with smoke to the rich, and it's hard to sell it at a high price."

Ruan Qingqing knew this, "Our previous practice was that after the firewood was carbonized in the kiln, we did not take it out of the kiln immediately, but instead isolated the charcoal in the kiln to cool it down. The charcoal obtained in this way is called black charcoal, which produces smoke when used.

I have read in a book that if the red-hot charcoal is taken out of the cellar and exposed to air, the volatiles generated by pyrolysis are refined at high temperatures, and then covered and cooled. The charcoal at this time is not only hard, but also has residual white ash on the surface, so it is called white charcoal. That is, smokeless charcoal. Sir, we can give it a try! "

"Okay, let's take out a charcoal kiln and give it a try. If it succeeds, we will dig a few more charcoal kilns. Smokeless charcoal is expensive and easy to sell, but ordinary people like us are reluctant to use such expensive charcoal. So we can't stop burning smoke charcoal."

Mr. Ruan frowned and thought seriously.

"Well, you have thought it through carefully. In fact, I have a kind of charcoal that I would like to burn even more!" Ruan Qingqing said with lowered eyebrows.

After taking a puff of his cigarette, Mr. Ruan glanced at her and asked, "Is the charcoal you want to burn more useful?"

Ruan Qingqing thought for a moment, "Each has its pros and cons! Bamboo charcoal is not easy to burn, but if it does burn, it is more durable than ordinary charcoal, and it produces less smoke and does not choke people.

However, the main reason why I want to burn bamboo charcoal is because I want the watery substance I get during the process - bamboo vinegar.

This thing not only promotes the germination, rooting and growth of crop seeds, improves the quality and yield of crops, but also improves the soil and kills pests and weeds in the soil.

If we want to increase our crop yields next year, we can only find ways to prevent pests and diseases, use seeds, and other methods to improve the quality and yield of crops."

"Are there so many benefits?" Mr. Ruan couldn't believe it.

"Yes. In addition to the benefits I just mentioned, it can also remove odors. Spray a little in the toilet and the odor will be much better. It can also be used to treat dermatitis, athlete's foot, and itchy diseases. It can also improve the meat quality of livestock and farmed fish, and improve the quality of fish eggs, etc."

Ruan Qingqing added.

"It's so magical! We should get some. Any charcoal is charcoal, and we have plenty of bamboo!" Grandpa Ruan said excitedly.

"Yeah! I thought so too. But burning bamboo charcoal is a bit troublesome. We need to build a cave."

"The cave we dug is not good enough?"

"No, it's a little different from the way charcoal is burned. Another reason is to make it easier to collect bamboo vinegar." Ruan Qingqing shook her head.

“That way, there won’t be enough manpower.”

Mr. Ruan's forehead was wrinkled into a shape called "川".

"Master, this is why I came to you. I think it would be better to share the method of burning ordinary charcoal with your trusted relatives or other villagers, and you can be responsible for taking a share of the profits.

We mainly deal in smokeless charcoal and bamboo charcoal. What we can foresee now is that even if the demand for bamboo acetic acid in bamboo charcoal is not high next year, it will definitely increase significantly the year after next.”

Ruan Qingqing suggested.

"I'll think about it." Mr. Ruan did not agree immediately.

Ruan Qingqing sighed inwardly and said nothing more.

I continued to recall in my mind the bamboo charcoal burning cave and the specific process that I had seen before.

Because one of the topics she had researched before in Hua Xia was about using bamboo vinegar to improve soil.

In China's agricultural production, due to the excessive use of pesticides and fertilizers, pesticide residues and nitrate content in agricultural products exceed the standard, seriously affecting people's health and the sustainable development of agriculture.

The promotion and application of bamboo vinegar will effectively reduce the use of pesticides and improve the soil environment, and strongly promote the development of organic, green and pollution-free agriculture.

However, some pesticides and herbicides are not available here for a while. She had to take a different approach and use these pesticide substitutes to ensure high yields for everyone's crops.

However, it is easier said than done to collect bamboo vinegar, not to mention the subsequent separation and purification.

As for her grandfather, after hearing her talk about the many benefits of bamboo vinegar, he was in favor of burning bamboo charcoal at first. However, when it came to the difficulties encountered in burning it and the need to give up some interests, he still hesitated.

Ruan Qingqing knew clearly that Mr. Ruan's hesitation would most likely lead to nothing being done.

So she still had to find another way.
