The cost price of coarse salt or salt is about 5 wen per catty, and the cost price of refined salt sold to the state is at least 25 wen, and the official family will extract about 60 percent of the profit, so their profit per catty of salt is about 5 wen. Don't underestimate this data, the big the foundation, the higher the profit.

Once Tangjia Village has the qualifications to sell illicit salt, it can be opened to the outside world to sell illicit salt, and the next profit will be more than ten times the current annual income of Tangjia Village, except for the cost of filial piety, transfer envoys and local officials.

Therefore, it is nothing for the Tang patriarch to cut some meat in advance, with the salt recipe and the refining technology of refined salt, it can also ensure the peaceful life of Tangjia Village for a hundred years. With the salt certificate, they can buy the salt pan boldly and use their own people to mine, and the cost is greatly reduced.

In this way, the expressions on the faces of the people below have changed.

This is a big piece of fat, if anyone has this technology, why worry about not making money. It's not too much to earn a mountain of gold a year.

Those people were all human spirits, and they immediately wanted to congratulate the Tang patriarch, and said that they must take care of them more in the future.

Patriarch Tang did not refuse, and said kind words in his mouth, saying that in the future, he would have to rely on everyone's help and make a fortune together.

Now that the temple fair has been used to spread the news that their Tangjia Village can make refined salt, the next thing is to do a big job. After the marriage of Tang Sizhe and Tang Ruyue is decided, everything will be settled.

Gu Yunzhi's injury in Tangjia Village is a bit troublesome, but there is a wrong, a debtor, anyway, there is that girl herself, they just need to go through the motions and not lose their proportions.

Therefore, after Gu Yunzhi was injured, he ordered someone to vacate the best room, invited Dr. Xu, and invited other famous doctors from near and far to come for consultation.

Compared with the matter of salt, Gu Yunzhi's personal life and death are not so important.

This day is destined to be not peaceful. After people from all walks of life received this important news from Tangjia Village, they spread it one by one.

"Ah Juan, don't worry, I'll find a way to save Young Master Gu."

"Brother Lu, you know everything? Please help me find a way, if something happens to him, I'm a murderer. When Tang Wanwan raised her head, there were tears in her eyes. She doesn't believe in gods and Buddhas, and she doesn't believe that there are elves and ghosts in this world, but she hopes that God can hear her prayers and not let Gu Yunzhi die.

"Ah Juan, don't worry, I'll do my best." Lu Yujin gently shook Tang Wanwan's hand, and then let go again.

"Besides, I have something I want to ask you."

"Well, Brother Lu, you say?" Tang Wanwan looked at Lu Yujin.

"Do you know how to refine salt?"

Tang Wanwan smiled and said, "You also saw it, it's just nothing to mess around at home." ”

"I'll help you demolish your house later, in case someone asks about you, don't admit that you know? I have my own plans for this. I'm here for your own good. ”

Seeing Lu Yu's cautious expression, Tang Wanwan knew that he was not joking, so he asked, "Is something wrong?" Tang Wanwan thought about it in her heart, Tang Ruyue asked herself that day, and the others didn't seem to show excessive concern.

Something must have happened to her, right? The salt thing is no small thing.

"You'll know in two days, anyway, no matter what happens, you can come to me."

"And this one for you, in case you have something urgent, you just throw this into the air, and I will come to you." Lu Yu stuffed a few paper stacks into Tang Wanwan's hand. There were some strange symbols on it, Tang Wanwan looked at this symbol, and a name suddenly appeared in his mind.

Messengers.

A low-level rune used to convey information. Learn how to use spells, pinch tricks. Learning opportunities, unlocked.

Seeing this line of explanation, Tang Wanwan was stunned. This appeared again, and Tang Wanwan found that as long as something new appeared around him, there would be an explanation. What exactly does it mean to be unlocked? Will it unravel itself later? Is it possible to unlock it when she gets stronger?

"Who the hell are you?" Tang Wanwan looked at Lu Yujin, obviously having something to say.

Lu Yujin didn't expect Tang Wanwan to ask such a question, but after thinking about it carefully, he understood. After all, his communication paper crane is not an ordinary thing. He smiled at her and reached out to stroke her hair. "Silly girl, no matter what my identity is, I will always be your big brother Lu. Remember, no matter what happens to you, don't rush. Waiting for my news. ”

"Okay, thank you, Brother Lu."

Lu Yu knows how to cultivate talismans, who is he? She became more and more curious about Lu Yujin.

However, just like Lu Yujin said, the less you know about some things, the better, and since he said so, she believed him.

When Tang Wanwan followed them, her expression was very calm, and her composure was not like that of a girl of her age. Ordinary women, when they encounter something like today, they are already stupid. Tang Wanwan's mind was also chaotic when she saw a large amount of blood spurting out of Gu Yunzhi's chest, but now seeing so many people pointing at her, she calmed down instead. must find a way to save Gu Yunzhi, and can't let him have something.

"Can I go in and take a look at the Young Pavilion Master?" Tang Wanwan knew that she was going to be locked up, and before entering, she wanted to take a look at Gu Yunzhi and wanted to know his current situation.

"You murderer, if you dare to come, I will kill you." Gu Xinwen saw that her eldest brother was stabbed for herself, and her life and death were uncertain, so she was honest for most of the day. Now I saw Tang Wanwan appear, and she was like a fried cat, showing her teeth and claws.

However, before her fist hit Tang Wanwan's face, she grabbed it, and then threw her aside.

Gu Xinwen snorted in pain, she didn't dare to mess around anymore, she knew that Tang Wanwan was not a vegetarian, and she would not care about her identity at all.

"Be honest and go in." The elder gave a look, and the other two grabbed Tang Wanwan's arm one by one, and escorted her into the small black room next to the ancestral hall of the Tang family.

This little black house, Tang Sizhe just stayed a few days ago. There is futon inside, and everything to eat.

When Tang Wanwan walked in, he was almost slipped by the melon seed shell in one place.

Huang Zheng and the others also knew that Tang Wanwan had been arrested, so they came over to comfort her and said, "Ah Juan, don't worry too much, the young pavilion master Jiren has his own natural appearance, and he will definitely wake up." Doctor Xu had already helped Gu Yunzhi bandage and stop the bleeding, but his knife was pierced very deeply, and the blood kept flowing, if he couldn't stop the bleeding, it would be dangerous to keep bleeding.

"Do you know what drugs Dr. Xu uses? Can you show me the recipe? ”

"Okay, I'll take a look." Huang Zheng is an understanding person in his heart, unlike Gu Xinwen who is a madman.

Gu Xinyu has been staying by her brother's bedside, crying several times, and she will sit weakly next to the bed, anxiously waiting for Gu Yunzhi to wake up.
