...

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

"No, just report and submit new salt, and don't submit the salt method."

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

"It's okay if your Majesty wants to hand over it, but County Magistrate Zhang can't watch Lu's salt and rob it for others. The Zhang family and Lu are allies." Ao Wu said.

Zhang Xutuo presented this new salt-making method to Yang Guang. This is a political achievement that can help him get promoted. Ao Wu didn't care about the merits to his family, but his interest relationship had to be given. Although his relationship with Lu was not very reliable, Lu was sent to him to be Ao Wu's subordinate. But after all, she was considered her subordinate. Then Zhang Xutuo took the benefits and of course he had to form an alliance with Lu.

After hearing this, Lu's eyes were delighted and excited.

Zhang Jingxuan heard it and nodded and said, "Of course. It's too late for me to welcome him!"

"Let me write down the salt method. I will talk about the salt making method again. I will not be in charge of the salt again." Ao Wu expressed his opinion. If he had to focus on cultivation, he would not be in charge of the salt.

Zhang Jingxuan quickly took out a brush and a scroll cloth from his sleeve. The brush stroked the sticking tongue. It was wet and could write. He looked up at Ao Wu expectantly.

The ancients thought that there was less ink in their stomachs. The brush became hard after dipped ink. Can you do this twice on your tongue?

As expected, Ao Wu could not argue with the ancients. He said, "This is saltpeter. You can pour it into the water to freeze the water. Saltpeter cannot be mixed with salt, so you can use a large pot to cover a small pot."

Zhang Jingxuan wrote down.

"I just said that your salt is not salt, because it is because your salt is too stolen. I am afraid it has something to do with your salt fields not being clean and the salt water not being clean. Especially for the salt-dried fields, not only are the fields stolen, but it will take more than a month to dry them. It is impossible to prevent the stolen goods from falling in for such a long time. Therefore, the dried brine is stolen, and the salt produced in this way will not be white."

"My new method of salt making is to use the method of freezing. Ice usually only contains water, but very little salt. After the brine is frozen, the ice formed is equivalent to taking out the water in the brine. It is the same as evaporating the water gas in the salt field, so the rest is brine."

"Just prepare enough saltpeter and make a long two-layer tank to cleanly make salt."

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

After he finished writing, he lowered his head and pondered for a long time.

After a while, he sighed: "I really didn't expect that the small salt making method would have such a magical method to dry it into brine. I only knew how to dry it, but I didn't expect that I could use ice to freeze it!"

"That's right, you don't need saltpeter in winter, but you don't need saltpeter in other times." Ao Wu replied.

The salt owner next to him said excitedly: "In this way, you don't have to dry the beaten salt water for more than a month. Just pour it here and freeze it with ice to get the brine. You will only get the salt once every two or three months, and now it can get it once every half a month!"

Another man said: "And there is no need to use hundreds of acres of land to dry salt!"

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

There are salt merchants, salt merchants, and salt owners here, all of whom are experts. They can see the infinite benefits of this place at a glance, and their faces are full of smiles.

Zhang Jingxuan said happily: "My benefactor, there is another wonderful method here. Zhang believes that if you offer it to Your Majesty, it will be a great achievement. Your Majesty is in Jiangdu, and it is at the end of the summer. It will be hot all the way, and it is difficult to store ice in the cellar on a boat. If you present the method of making ice in saltpeter to Your Majesty, so that Your Majesty can also eat cold food on the boat, you will definitely be happy."

This is what Zhang Jingxuan wants to flatter. Ao Wu said: "This is part of salt making, you can offer it together."

Zhang Jingxuan felt that Ao Wu was the lucky star of his Zhang family. When his father, the pillar of the head, saved his father. Now when the family encountered a bottleneck, he came to give him two wonderful methods in a row. The Zhang family won the favor of His Majesty and was not far away when they were promoted.

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 headed towards the stream where the purple-hearted umbrella grass was temporarily planted.

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

Ao Wu saw several people by the stream from afar and frowned.

They are five men and one woman, wearing strong clothes, blue and black, holding weapons and swords. Their aura is different from ordinary people. They are obviously people with martial arts skills, and there may be practitioners in it.

The purple heart umbrella grass is not far from them. They didn’t find it?

Ao Wu accelerated his pace and walked towards them.

They also discovered Ao Wu and looked at him vigilantly, and even more cautious people had already drawn their swords and left their sheaths.

There was a man in the middle, tall and black outfit, strangled the developed muscles on his chest. He looked at Ao Wu, who was still walking towards them without stopping, with a steady pace, but he could not tell whether he was a fellow man.

He was obviously the most prestigious person in this group and said, "Let's go."

The other people were surprised when these words were said.

The only woman asked the other people's thoughts: "Senior Brother Murong, this person knows our whereabouts and cannot keep him. Why should he leave?"

The man known as Murong said calmly: "It is not appropriate to have troubles, let's go and meet others."

The other people were even more surprised when they heard this. Could so many people be afraid of trouble when dealing with a person? Is Senior Brother Murong afraid of this person? But I can't see how powerful the scholar who came here is, but he is just stronger.

However, Murong not only has the highest cultivation level among them, but also has the highest prestige. They all have to listen to Murong's words in this trip. They had to shut up.

Murong turned around and headed downstream first.

At the time of leaving, Murong's eyes fell on a water grass by the stream, slightly ecstatic. The grass seemed familiar and seemed to be a little different, but she couldn't remember it.

When the others saw Murong leaving first, they followed.

Ao Wu approached them more and more. At this time, he saw that the purple heart umbrella grass by the stream was intact, and they seemed to be just staying by the stream, and they didn't notice the purple heart umbrella grass at all. At this time, when they saw that they were coming, they turned around and left, and they breathed a sigh of relief.

That's fine.

I found the wooden barrel that had been decorated with purple-hearted umbrella grass not far away. Unfortunately, it dispersed, but the wooden barrel was assembled just a few pieces of wood. There was no need to worry about it dispersing. Ao Wu found all the parts of the wooden barrel and started assembling it.

Murong, who had walked not far, suddenly stopped.

As the other five people looked at him curiously, he asked the only woman: "Junior Sister Xiao Cai, you are born to have the ability to remember the spiritual herbs, right or not?"

The Lingcao Book is an ancient bamboo slip book of the master, which records various spiritual herbs from the ancient martial arts world. However, spiritual herbs are treasures of heaven and earth, and are very rare. Spiritual herbs were still easy to find a thousand years ago. Everyone read the Lingcao Book. When they saw it in the mountains, they could recognize it, so they picked it back and made it a pill with powerful success. But now even if they go deep into the mountains and forests, it is difficult to find a spiritual herb. Therefore, this spiritual herb score has become increasingly useless.

So although people in the ancient martial arts world have read the spiritual herbs at the request of the master, they will let go after reading it. After a long time, they have not used the above knowledge and everyone has forgotten it.

The purple-heart umbrella grass is one of the spiritual herbs recorded above.

Murong just felt that the purple heart umbrella grass looked familiar, and the initial impression was from the spiritual grass.

However, he did not remember what the Purple Heart Umbrella Grass was, and the Lingcao Grass Records record the world's spiritual grass, and maybe there are some on it.

He forgot the spiritual herb score, but fortunately his junior sister has a good memory, so she should still remember it.

When he heard Murong's question, the woman known as Xiao Cai was surprised and replied: "Of course I remember."

"There is such a grass that grows in the water, and the grass has purple threads..." He described the shape of the purple-hearted umbrella grass he just saw, "Is there any record of this grass in the spiritual herb spectrum?"

"...It looks like a fairy scattering flowers in the Nine Heavens..." Xiao Cai murmured, and she exclaimed: "Isn't this a fairy scattering flowers in the Nine Heavens? Why did the senior brother ask about this?"

The name of the Purple Heart Umbrella Grass in the ancient martial arts world was transformed into a fairy, and the Nine Heavens Fairy Scattered Flowers and Grass is even more fairy-like.

As Xiao Cai said this name, a glimmer burst out from Murong's eyes!

"Yes, it's it!"

Xiao Cai was stunned for a moment, as if thinking of something, and asked, "Senior brother saw the Nine Heavens Fairy's scattered flowers and plants? Where is it?"

"That's right, just by the stream we were just staying, there was such a Nine Heavens Fairy scattered flower and plant. Let's go back and take the grass back to the master's sect." After that, he turned around and walked back first.

Xiaocai and the others were happy and quickly followed.

Xiao Cai remembers Superman, while walking, she told the effect of the Nine Heavens Fairy scattered flowers and plants: "The Lingcao Book says that planting this grass in the living room can prolong the life of ordinary people, and practitioners can speed up their cultivation. The leaves, branches and roots all have different medicinal effects, and can be the main medicine for 108 kinds of medicines."

This statement further strengthened everyone's determination to get the Nine Heavens Fairy's scattered flowers and plants.

They quickly walked back to their original place.

But they suddenly stopped and saw a man squatting by the stream. The nine-day fairy scattered flowers and plants that caused their passion were blocked by his body.

Ao Wu was digging the purple heart umbrella grass at this time. No matter what, compared with the noble, elegant and elegant name of the "Nine Heavens Fairy Scattering Flowers and 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 you can use spiritual herbs.

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

Seeing the scholar who had just forced them to retreat, he was squatting next to the spiritual grass, and Murong and others were considering:

Or can't you?
