Chen Wanrong did not object to Chen Zairong's entry into the army. It may not be a good thing to join the army with Chen Zairong's excellent conditions, but the two elders were too worried and in order not to make them worry, they had to help dispel this idea.

If Chen Zairong insisted on joining the army, Chen Wanrong had to find a way to help convince the second elders. Unfortunately, he did not insist. Chen Wanrong couldn't explain clearly whether it was a good or a bad thing to do so.

It was a good ending to be able to resolve things like this. After all, a family storm has ended, and Chen Wanrong was also happy. Seeing the three of them hugging each other and crying, Chen Wanrong couldn't help but wipe his tears.

Chen Wangshi wiped her eyes and comforted her: "No matter how lucky you are, don't cry! Old man, look at you, why are you crying?"

Chen Laoshi stretched out his calloused hand to wipe Chen Zairong's tears, and said lovingly: "Zairong, don't cry." Chen Zairong nodded sensiblely, wiped his eyes and stopped crying.

"Wanrong, thanks to you today." Chen Wangshi was praised for the first time for the first time.

A few times, in order to dispel Chen Zairong's idea of ​​dropping out of school, Chen Laoshi had even had the idea of ​​dying, and threatened Chen Zairong with death to have to surrender. Today, Chen Wanrong intervened and easily resolved the storm. Chen Laoshi was beyond his expectations and had to accept Chen Wanrong's ability to coordinate and couldn't help but praise him.

"Brother, thank you." Chen Zairong also came to thank him. Chen Wanrong's ability to reconcile conflicts takes into account all parties and can accept it. What's even more rare is that he praised Chen Zairong's moral character of knowing his mistakes, which impressed Chen Zairong. This thank you very sincerely.

Chen Wanrong smiled with relief and said, "Don't say those polite words, eating in the same pot seems to be more generous. Dad, take a rest first, I'll give you vinegar."

Who is so filial? Chen Zhongshi was so happy that his eyes were only a small slit: "How can that happen? Wanrong, let me do it myself." He said he did it himself, but he sat down with a cracked mouth, crossed his legs, and prepared to enjoy the family happiness of giving his son filial piety.

Chen Wangshi gave him a blank look and exposed his mentality: "Look at you, I'm talking so hard that Shan Xiang can do it himself, but she can't sit still."

Chen Houshi not only did not feel embarrassed, but was content with satisfaction and joy. He laughed twice as much as he answered.

"Brother, I'll do it." Chen Zairong rushed into the stove, poured vinegar into the clay pot, brought it to the stove, and simmered it in the fire.

This storm was caused by him today. He wanted to be filial to Chen honestly, so Chen Wanrong would not argue with him and let him do it.

The fire in the stove was strong, and the vinegar became hot in a short while and the sour smell was floating all over the house. Chen Zairong brought the clay pot to the table, picked up a piece of alum with chopsticks and put it in the hot vinegar. After stirring, the alum dissolved in the clay pot.

"Dad, drink it." Chen Zairong handed the hot vinegar to Chen Laoshi and called him sweetly.

"You put it, I'll do it myself." Chen Laoshi declined, but his hands had already taken it. The sour vinegar that was sour and toothless was like a delicacy in his mouth. He drank it in a few sips, and the gurgling sounds rang one after another.

After drinking, he flipped over the clay pot and shine it on the bottom of the pot. He opened his mouth very comfortably, as if he was drinking fine wine. Mrs. Chen criticized: "What's so bright? I haven't drunk it!" To Chen honestly now, this sour vinegar is not comparable to wine, it is nectar and jade liquid, with a long charm and endless aftertaste.

Chen Wanrong was very happy about Chen's honest and childish performance and couldn't help but smile.

"It's getting late, I'll go make dinner." It's almost dark, and Chen Wangshi stood up and went to the kitchen.

Chen Laoshi then realized that his work had not been finished, so he stood up: "I'm going to do it a few times. I'm going to do it. No matter how Rong, you're going to do it." It's really rare to go to work alone, but Chen Wanrong didn't ask him to start.

Chen Wangshi teased him: "Where did the sun come out today? You don't want Wanrong to help you."

After resolving this storm, Chen Wanrong's position in Chen Laoshi's mind has changed drastically. He is no longer the wood that allows him to call him around, but a smart and alert person. Chen Laoshi is embarrassed to send Chen Wanrong again and find excuses to criticize Chen Wang: "Look at you, what's your heart? Wanrong is sending a bucket today. The weather is so cold and exhausted, so he won't let him rest for a while."

Chen Wang and his couple who had been with him for decades were very clear about his twists and turns. They knew that he was stubborn and laughed, gave Chen a honest look, and then entered the kitchen.

I bought the alum and salt and had not yet prepared the reagent, so I took this time to make it. Chen Wanrong suppressed his laughter and went to the stove to take a wooden basin. He scooped some boiling water from the jar where he sat and put it in the wooden basin. He poured half a basin of cold water and stirred it evenly with a wooden stick. He reached out and tried it. The temperature was quite appropriate.

After pouring all the alum into the basin, Chen Zairong stretched his neck long and asked in confusion: "Brother, why are you doing this?"

"Make something." Chen Wanrong stirred in the basin with a wooden stick.

Chen Zairong's curiosity aroused. While rolling up his sleeves, he said, "Brother, I'll help you stir." He grabbed the wooden stick from Chen Wanrong's hand, held it with both hands, and began to stir.

The mixing of the reagents requires moderate and even strength, slow speed, not too fast. He did not know these requirements, and he took out the posture of practicing martial arts, how much force he was to use. If he used too much force, the water would flow rapidly, and a hollow vortex appeared in the middle.

From the perspective of martial arts, water flows at such a high speed in the basin without overflowing, he has great control over the force, but this is a chemical operation and is absolutely unqualified. Chen Wanrong hurriedly advised him: "Slow down, slow down. Don't have too much strength, moderate and even, don't be too fast, just stir slowly."

"Brother, don't worry, I'm good at this, no matter how fast it is." Chen Zairong didn't understand that this was a chemical operation, not a martial arts practice, and Yan Lai was quite proud.

If you don't slow down, it will definitely overflow. Chen Wanrong's tone has increased a lot: "Slow down!"

"Oh." Chen Zairong said a few times, then he slowed down. The water slowly flowed. Chen Wanrong affirmed: "That's it."

The alum crystal slowly dissolved until it was completely dissolved. Chen Wanrong poured almost two kilograms of salt into it.

Chen Zairong was confused again: "Brother, why are you pouring salt? This is not cooking."

Tanning is a key step in turning the leather into leather, which is related to the quality of the leather. Tanning of leather needs to be carried out in weak acidity. Dissolving alum in water will produce free sulfuric acid, which can promote the absorption and expansion of protein fibers in the skin. The purpose of adding salt is to inhibit excessive expansion.

This complex chemical process cannot be explained to Chen Zairong, a person who has no basic knowledge of chemistry, so Chen Wanrong simply does not explain it.

There are many methods for tanning leather. The methods used in modern society include chrome tanning, plant method, aldehyde tanning, oil tanning, and alum method. Among them, chrome tanning is the most common, because the biggest advantage of chrome tanning is that it takes only two or three hours to meet the requirements, while other methods are longer, dozens of hours, or even a week.

For Chen Wanrong, the use of chromium tanning method was out of reach. There was no chromium trioxide in the Tang Dynasty, and there was no such condition even if it was made. Alum and salt were relatively common in the Tang Dynasty, and raw materials were easily obtained.

More importantly, alum is cheap, a few cents per pound, and salt is relatively expensive for ten cents per pound. Compared with the profit, this cost is very low and the investment is not large. It is very suitable for Chen Wanrong to start a business from a poor family. Therefore, Chen Wanrong chose the alum method.

Until all the salt dissolved, Chen Wanrong said: "Okay."

Chen Zairong put the wooden stick on, couldn't help but be curious anymore and asked, "Brother, what are you doing?"

"Sell money." Chen Wanrong replied very simply, frowned: "You have to find something to put it on."

"Can this be sold for money?" For Chen Zairong, alum and salt are common things, and they usually do not attract people's attention. If he can sell for money by dealing with it like this, he would not believe it anyway, but he still actively solved the problem for Chen Wanrong: "Brother, there is a bucket upstairs, which has not been used for a long time, and it is just right. I'll get it for you."

Without waiting for Chen Wanrong to speak, he grabbed the wood stretching out from the building with both hands, as light as a monkey flying in the mountains, and rushed upstairs with a slight stroke.

It was more than ten feet tall and it was so easy to get up. The skill of the hand was very beautiful, and Chen Wanrong praised it.

Chen Wanrong's admiration was not over yet. Chen Zairong had already appeared at the entrance of the building with a wooden barrel. Chen Wanrong hurriedly said, "Wait, I'll move the ladder for you."

"Brother, what ladder do you want? You don't know my ability." Chen Zairong jumped and jumped down from the building. He only made a slight sound at a height of more than 1 meter. This skill is very handsome, and Chen Wanrong applauded again.

A smoky smell hit his nostrils. Chen Wanrong saw the barrel of black and covered with smoke and dust. I don’t know how long no one has used it. It seems that it is easy to wash.

"Brother, do you want the lid? If you don't, I'll throw it upstairs." Chen Zairong held up the black lid and tried to throw it away.

Chen Wanrong hurriedly stopped him: "You have to wait. When I wash it, you can write a few words on the lid."

Chen Zairong threw a series of questions over: "Brother, why do you need to write? What words do you write?"
