……

Faced with Lu's doubts and worries, Zhang Jingxuan hurriedly explained:

"No, just report and hand in the new salt, you don't need to hand in the salt production method."

Lu didn't understand the things in the officialdom, and when he heard this, he was relieved.

"It doesn't hurt if Your Majesty wants to hand it over, but Zhang Juncheng can't watch the Lu family's salt robbed by others. The Zhang family and the Lu family are allies. Ao Wu said.

Zhang Xutuo took this new salt-making method and presented it to Yang Guang, which was a political achievement that could help him get promoted. Ao Wu doesn't care about the credit given to his family, but the interests have to be given. Although the relationship with the Lu family is not very reliable, the Lu family was sent to the door by himself to be Ao Wu's subordinate. But how to say that she is also her own subordinate, so Zhang Xutuo took the benefits, of course, she had to form an alliance with the Lu family.

When Lu heard this, his eyes were happy, and he was so excited that he couldn't do it.

And Zhang Jingxuan heard it, nodded and said, "Of course." It's too late for my Zhang family to welcome! ”

"Find a pen to write it down, and I will explain the salt making method again, and I won't care about this salt in the future." Ao Wu said that his mind should be on cultivation, how could he care about salt.

Zhang Jingxuan hurriedly took out a brush and a scroll cloth from his sleeve, and the brush scratched on the tongue that stretched out, it was wet, and he could write, and looked up at Ao Wu expectantly.

This ancient man thinks that the ink in his stomach is relatively small, and this brush has become hard after the ink, so you can do it twice on your tongue?

Yes, Ao Wu couldn't deal with the ancients, he said: "This is saltpeter, you can pour it into the water and let the water freeze." Saltpeter can't be mixed with salt, so use large pots for small pots. ”

Zhang Jingxuan wrote brush-by-brush.

"I just said that your salt is not salt, because I see that your salt is too rich, and I am afraid that it has something to do with the uncleanliness of your salt fields and the unclean salt water. Especially in the field of drying salt, not only the field is stolen, but also it will take more than a month to dry, and it is impossible to prevent the stolen things from falling into it for such a long time, so the dried brine is stolen, and the salt that comes out will not be white. ”

"My new salt-making method is based on the method of freezing. Ice, generally only contains water, and very little salt, after the salt water has been frozen, the ice formed, is equivalent to taking out the water in the salt water, and the evaporation of water vapor in the salt field is a reason, then the rest is only brine. ”

"As long as you prepare enough saltpeter and make a long, two-layer trough, you can make salt cleanly."

After Ao Wu finished speaking, Zhang Jingxuan also finished writing.

When he finished writing, he lowered his head and pondered, and was silent for a long time.

After a while, he sighed: "I really didn't expect that there is such a magical way to make small salt, which is dried into brine, but I only knew how to dry it, but I didn't expect it to be frozen with ice!" ”

"That's right, saltpeter is not used in winter, and saltpeter is used at other times." Ao Wu replied.

The salt farmer next to him said excitedly: "In this way, there is no need to dry the salt water for more than a month, just put it here and pour it, freeze it with ice, and you can produce the brine, and the salt will only come out once in two or three months, and now it can be released once every half a month!" ”

Another said, "And you don't have to dry hundreds of acres of land for salt!" ”

Frozen salt production saves land and time, and is much more efficient than the traditional salt drying method.

There are salt farmers, salt merchants, and salt owners, all of whom are connoisseurs, and they can see the infinite benefits of this place at a glance, and their faces are smiling.

Zhang Jingxuan said happily: "Engong, there is a wonderful method here, Zhang thinks that if it is dedicated to His Majesty, it will be a great achievement." His Majesty went down to Jiangdu, at this time it was the end of midsummer, and it must be very hot all the way, and it was difficult for the boat to store the cellar ice. If you offer the method of saltpeter ice to Your Majesty, so that Your Majesty can eat cold food and drink on the ship, you will definitely be happy. ”

This is Zhang Jingxuan who wants to take it to pat his ass, Ao Wu said: "This is part of the salt making, you can offer it together." ”

Zhang Jingxuan felt that Ao Wu was the lucky star of his Zhang family, when his father's pillar was critically ill, he saved his father, and now when the family encountered a bottleneck, he came to send two wonderful methods in a row, and the Zhang family won the favor of His Majesty, and the time for promotion was not far away.

When Zhang Jingxuan passed the news to Zhang Xutuo, the steady Zhang Xutuo couldn't help but run out to find Ao Wu, but Ao Wu had already left at this time.

He entered Mount Tai and went to the brook where the purple heart umbrella grass had been planted temporarily.

After half a day, I finally arrived at the creek, which was lush and the water was cool.

Ao Wu saw several people by the stream from a distance, and couldn't help frowning.

There were five men and one woman, dressed in strong suits, some green and some black, holding sabers, and their breath was different from that of ordinary people, they were obviously people with martial arts, and there might be cultivators in them.

The Purple Heart Umbrella Grass is not far from them, they can't find it, right?

Ao Wu quickened his pace and walked towards them.

They also spotted Ao Wu and watched him vigilantly, and the more cautious ones had already drawn their swords from their sheaths.

The middle person, tall, black power suit was stretched out of the well-developed muscles of his chest, his eyes coldly looked at Ao Wu, who was still walking towards them without stopping, walking with a steady pace, but he couldn't see his cultivation, and he couldn't tell whether he was a fellow believer.

He was obviously the most prestigious person in the group, and said, "Go." ”

As soon as these words came out, they surprised several other people.

The only woman asked the words in the hearts of the others: "Senior Brother Murong, this person knows our whereabouts, and we can't keep him." Why leave? ”

The person known as Murong said calmly: "It's not appropriate to make extraneous branches, let's go and meet the others quickly." ”

Several other people were even more surprised when they heard this, could it be that so many people would be afraid of extraneous branches when dealing with one person, could it be that Senior Brother Murong was afraid of this person, but he couldn't see how powerful this scholar who came over was, but he was just physically stronger.

However, Murong is not only the highest in cultivation, but also the highest in prestige, and they all have to listen to Murong's words on this trip. They had to shut up.

Murong turned around and went downstream first.

At the time of leaving, Murong's eyes fell on a water grass by the stream, slightly distracted, this grass seemed to be a little familiar, it seemed to be different, but he couldn't think of it.

When the others saw Murong leave first, they followed.

Ao Wu approached them more and more, and at this time, he saw that the purple heart umbrella grass by the stream was unharmed, and they seemed to just want to stay by the stream, and did not notice the purple heart umbrella grass at all. At this time, when they saw themselves coming, they all turned around and left, and they were relieved.

That's fine.

Not far away, I found the barrel of the purple heart umbrella grass that the green tiger had before, but unfortunately it was scattered, but the barrel was assembled with a few pieces of wood, and there was no need to worry about scattering, Ao Wu found all the barrel parts and began to assemble it.

Murong, who had walked not far away, suddenly stopped.

When the other five people looked at him curiously, he asked the only woman: "Senior Sister Xiaocai, you were born with the ability to remember the spirit grass spectrum, yes or no?" ”

The Lingcao Book is an ancient bamboo book of the Shimen, which records various spiritual grasses in the ancient martial arts world. A thousand years ago, the spirit grass was still easy to find, everyone read the spirit grass spectrum, and when they saw it in the mountains, they could recognize it, so they picked it back and made a powerful medicine pill. But now, even if you go deep into the mountains and old forests, it is difficult to find a spirit grass. Therefore, this spirit grass spectrum is becoming more and more useless.

So much so that the people in the ancient martial arts world, although they have all read the spirit grass spectrum at the request of the master, but after reading it, they put it down, and they have not used the above knowledge for a long time, and everyone has forgotten it.

And the Purple Heart Umbrella Grass is one of the spirit grasses recorded above.

Murong just felt that the Purple Heart Umbrella Grass was familiar, and his initial impression was that it came from the Spirit Grass Spectrum.

However, he didn't think about what the purple heart umbrella grass was at this time, and the spirit grass spectrum recorded the world's spirit grass and different grasses, maybe there were on it.

He forgot the Lingcao spectrum, but fortunately, his junior sister has a good memory, so he should still remember it.

Hearing Murong ask like this, the woman known as Xiaocai was strange, but still replied, "Of course I remember." ”

"There is such a kind of grass, born in water, and the grass has purple threads...... "He described the shape of the purple heart umbrella grass he saw just now, "This kind of grass is recorded on the spirit grass spectrum?" ”

“…… Shaped like a Nine Heavens Fairy Scattered Flowers......" Xiao Cai muttered, at which time she exclaimed, "Isn't this the Nine Heavens Fairy Scattered Flowers and Plants?" Why did the senior brother ask about this? ”

The name of the purple heart umbrella grass in the ancient martial arts world has been turned into a fairy, and the Nine Heavens Fairy scatters flowers and plants, which is more immortal.

As Xiaocai said the name, a fine light burst out in Murong's eyes!

"That's right, that's it!"

Xiaocai was stunned, seemed to think of something, and asked, "Senior brother, did you see the Nine Heavens Fairy Scattered Flowers and Plants?" Where is it? ”

"That's right, right next to the stream where we just stayed, there is such a Nine Heavens Fairy Scattered Flower Plant. Let's go back and bring the grass back to the master's gate. With that, he took the lead in turning and walking back.

Xiaocai and the others were overjoyed and hurriedly followed.

Xiaocai remembered Superman, and while walking, he told the effect of the Nine Heavens Fairy Scattered Flowers and Plants: "The spirit grass spectrum says that this kind of grass planted in the living room can make ordinary people live longer, and the cultivator's cultivation progress is very fast. Its leaves, branches, and roots all have different medicinal effects, and can be used as the main medicine of one hundred and eight kinds of medicines. ”

When these words came out, it strengthened everyone's determination to get the Nine Heavens Fairy Scattered Flowers and Plants.

They traveled fast and quickly returned to their original places.

But they suddenly stopped, and saw a man squatting by the stream, and the Nine Heavens Fairy Scattered Flowers and Plants that caused their blood were blocked by his body.

Ao Wu was digging the purple heart umbrella grass at this time, no matter what he said, compared with the noble and atmospheric name of the "Nine Heavens Fairy Scattered Flower Grass" in the ancient martial arts world, the name of this purple heart umbrella grass is full of ** silk temperament.

However, whether the name is good or not depends on whether or not you will use spirit grass.

Ao Wu obviously knew the effects of the Purple Heart Umbrella Grass better than them.

Seeing the scholar who had forced them back just now, he was squatting next to the spirit grass at this time, and Murong and the others were all considering:

To go up or not to go?
