PS: "Leisurely Datang" asks for subscription support!

In the past few days, although Cheng Yanjin, who is the general of Zuo Wuwei, is not afraid, he is inevitably a little worried in his heart.

It's not that I'm worried about salt making, not to mention that Zhang Cheng's team doesn't dare to cheat on this kind of thing, and I can't believe that others Cheng Yanjin can't trust his son.

The real concern is that although it has become a fact that it can turn poisonous salt into green salt, the efficiency of salt production is really slow and irritating.

In the first few days, I was tired and tired of getting 300 catties of green salt.

To say that this is a lot less, from a personal point of view, it is really not a small amount.

Not to mention looking at the entire Datang, even on the right side of Longyou, it is only a drop in the bucket.

But now, the daily output of green salt has directly increased from less than 100 catties to 1,000 catties, and this speed is even getting faster.

This also means that the problem of salt shortage in Longyou will never look back.

What makes Cheng Yanjin happiest is that with so much salt, not a single eldest son has spent it, and it is all for nothing.

Not to mention the green salt that can still be obtained later, just the thousands of catties that have been transported to the big camp are calculated according to the price of 500 wen a catty of green salt on the market, which is millions of dollars.

It's just that the elated Eight Cheng Biting Gold is also a bit of a headache.

After all, no matter how good this green salt that doesn't cost money, how can it be better than the method of turning poisonous salt into green salt.

According to the secret report sent back by his children, mining, grinding, boiling water, boiling salt, by the way, and the skills of barrel making have all been learned and all of them are proficient.

But the key link is now black.

This also means: Once he left the disciples of those two hidden masters, the poisonous salt was still poisonous salt, and he couldn't change it into green salt at all.

But a headache is a headache, and Cheng Biting Jin can actually understand this practice, after all, this secret method can definitely be regarded as priceless.

To compare the heart to the heart, if this method of turning poisonous salt into green salt comes from the old Cheng family, hehe...... Not to mention donating the method, whether you are willing to give away thousands of catties of salt is a problem.

Fortunately, according to the secret report sent back by Cheng Chumo, although the Lang Jun surnamed Li did not mean to sacrifice the method of making salt, he did not say it to death.

Inference from Cheng biting gold. That Li Langjun should have wanted to use the excuse of sending salt. Take the opportunity to make some requests.

Although the secret report sent to Chang'an City has not been replied to in the past few days, the result can already be imagined.

As long as it's not too much, there is this salt-making technology. This Li Langjun doesn't care what he asks. Most of the people in Chang'an City would agree.

No way. This secret technique of turning poisonous salt into green salt is too important for the entire Datang.

It would be important if it weren't for the fact that the identities and origins of the two brothers are extremely special, and the potential value is far more than just such a secret art.

The importance of turning poisonous salts into green salts. I'm afraid that those two Lang Jun have been locked up in the prison of Chang'an City at this time.

What did you say? Isn't it scientific that the king of a dignified country actually competes with the people for profit?

I'm sorry, but whether the king of a country or not competes with the people depends on how big the benefit is.

How many so-called poisonous salt mines are there in the entire Guanwai? How much economic benefit can it be caused by making green salt?

In modern times, what do you think would happen if someone invented technology that could turn discarded resources into sought-after items?

That's right, "Guo Jia" will definitely not come forward to compete with the people, because there is no need to come forward at all, and someone will do it below.

In fact, Cheng Yanjin also thought about calling the pair of senior brothers to his side to have a good talk, but the origin of the two is unknown after all, and the matter is too involved, and the will of Chang'an City is needed.

Just when Cheng Yanjin was happy and entangled, the guards outside the tent suddenly reported: "Big Shuai, Captain Cheng asks to see you." ”

"Let him get in for Lao Tzu." Cheng Biting Jin, who was a little entangled, directly opened his mouth and commanded.

As soon as he entered the handsome tent, Cheng Chumo saw his father sitting alone behind the desk, and his fingers knocked on the ground with the horizontal case in front of him.

Cheng Chumo, who didn't know what his father was thinking, knew very well how bad the other party's temper was in this state, so he hurriedly sang:

"Captain Cheng silently saw the marshal, five thousand catties of salt have been paid in full, and now he is ready to return to the salt field, I don't know what the marshal commands?"

There is no father-son relationship in the barracks, only generals and captains, superiors and subordinates, so it is not surprising that such a title is called.

Cheng Yanjin looked up at his son, and just as he was about to speak, he found that the other party felt something wrong with him.

Hey? Usually sloppy and sloppy, no, the son who should be unkempt has become clean and tidy, and his face is much more durable than before.

Well, there is no trace of the lice that can often be seen in the past, and there is a clear cleaned up armor, which is full of spirit inside and out.

"In the end, it's your own seed, enough spirit."

Cheng Biting Jin, who praised himself in his heart, suddenly became a lot happier when he was still entangled.

Seeing that his father's eyes were a little wrong, Cheng Chumo, who had been scared by the other party, hurriedly took out an oiled paper bag from his arms, and then respectfully handed it to the desk in front of his father.

Cheng Biting Jin, who was originally going to speak, moved his nose a few times in confusion, and the faint fragrance could easily determine that the bread here should be eaten.

Although I don't understand what my own child means, being able to enjoy the filial piety of the other party, even if it is just a bite of food, is already a very comforting thing for Cheng Yanjin.

Without saying anything at the moment, he opened the oiled paper bag with a smile, and saw a large cake in it, which was burnt and attractive, with the fragrance of wheat.

When you bite into it, the dough tastes good, crispy on the outside and soft on the inside.

What surprised Cheng Yanjin the most was that it was just bread, but he ate the taste of meat, and it was mutton.

After eating the cake in two bites, after picking up the cold tea in front of him and pouring two sips, Cheng Yanjin asked:

"This cake is really good, it tastes like meat even though it is a dough cake, and the cook in the camp should really pull it out and whip it."

"You kid, what is the meaning of deliberately bringing out this cake, hurry up and say it happily."

Seeing that he couldn't hide his father from this little bit of caution, Cheng Chumo hurriedly said:

"Dad, this cake is made by Young Master Yun, and meat powder is used in it, so it tastes meaty."

"Young Master Yun said, this meat powder is not limited to mutton, any meat can be."

"The child took out this bread because it tasted good and could satisfy his hunger by eating a piece in a hurry, and because it could be left for a short time even on a hot day."

As early as when he ate this cake, Cheng Yanjin also had this idea, and nodded immediately and said:

"Oh? There is actually this method of making cakes, it seems that the origin of this Young Master Yun is really extraordinary. ”

"Did the other party take out this cake?"

"Yes, not only this kind of cake, but also fried noodles, fried rice, and jerky, which can be eaten as military rations."

"It tastes good, and it can be put on for a short time on a hot day." Cheng Chumo, who nodded, hurriedly reported.

Originally, I thought that this kind of craftsmanship would be very useful to Datang, and the other party would not take it out so easily, Cheng Biting Jin was a little surprised.

But after thinking about it, the other party can even give those few eating methods that can make a lot of money to the women who accompany the army at will, and it is not surprising to do this kind of thing.

"Did those two little guys make any requests when they dedicated these methods to the imperial court?" After pondering for a while, Cheng Yanjin asked.

"Nope." Cheng Chumo, who shook his head, had some expressions that wanted to speak and stopped.

"Hun boy, if you have anything to say, just say it." Cheng Biting Jin, who glared at his son, said.

"Dad, judging from the child, those two young masters don't care about this thing at all, even the secret method of making salt." Cheng Chumo said cautiously.

"Oh? So why didn't he dedicate the method of salt making to the imperial court? Cheng Yanjin asked.

Seeing that his father didn't mean to make a fortune, Cheng Chumo said his speculation:

"According to the child, the two young masters don't want to offer, firstly, they want to make some requests, and secondly, they also know that this method of salt making is very important, and they are worried that it will ......."

Faced with such a statement, Cheng Yanjin groaned.

Cheng Chumo was a little apprehensive, seeing that his father had entered this state again, he gritted his teeth and said hard:

"Dad, Young Master Yun is a good person, and he made these military rations on purpose after he saw that we ate them too badly."

"Although Young Master Li doesn't seem to be very easy to speak, he is not a bad person, and during this time, the child has learned the skills of killing enemies from him."

"Pass my general order and order Li Anran and Yun Ye to come to the camp to see me quickly." Glancing at his own child, Cheng Yanjin suddenly shouted. (To be continued......)
