Datang: In order to be a salted fish, I decided to look forward to my father Jackie Chan

Chapter 122
"Your words are easy to say. You have been here for nearly half a month. Yesterday His Majesty wrote again to ask about our progress. I really want to sue you, saying that you are messing around in the dock all day long!"

Li Xiao was speechless in embarrassment, this Yantian seemed to be here for the second time today, but at the dock, she left early and returned late every day.

"Then thank you Uncle Cheng for covering for me!"

"One and a half months at most, His Majesty wants to see the salt, what do you think we should do?"

"Don't worry, don't worry, there's the housekeeper, he will figure out a way, besides, we have to look at God's face when we make salt, just do the basic work well first!"

Cheng Yaojin was furious, "This is about His Majesty's face!"

"I'm afraid of a ball, at worst I'll admit defeat!"

Li Xiao said nonchalantly, people live in this world, don't care too much about face, otherwise life will be tiring!

This evaporation pond is only five acres in size, and it didn't take long for it to be filled with seawater!
After the measurement, the officials of the Ministry of Industry reported to Cheng Yaojin with a bitter face, "Lu Guogong, Mr. Li, the evaporation pool is high in the north and low in the south. The water level is about one foot away!"

Cheng Yaojin didn't understand this, it was just one foot, not much, and he didn't understand why the people from the Ministry of Industry had a sour face and pointed to Li Xiao.

"Didn't you measure it when you built it?

Mr. Yang from the Ministry of Industry participated in the construction of the Grand Canal when he was young, "Master Li, I have measured it, but even if it is a canal, the accuracy is not as high as you require!"

Mr. Yang complained in his heart, the four sides plus the middle, the height error of the water level must be one centimeter, almost the height of a fingernail, this is too difficult, the tyrant Yang Guang is not so harsh!
"Hey, look at what this means, is Master Yang blaming me?"

"Don't dare, dare not, how dare I blame Lord Li!"

Mr. Yang said he didn't dare, but he was scolding his mother in his heart. If the layman commands the experts, if he can't do it well, the emperor can't take it out on me, Lao Yang, right?
Without professional equipment, Li Xiao couldn't measure it. He thought that since these people are talents from the Ministry of Industry, they must have a way, but they are still blind now!
Li Xiao sat down on a small stool beside the salt field, just thinking about something in his mind, there was still some distance between his butt and the stool, and he turned over on his back!
"Master Zan, be careful, it's okay!"

Cheng Yaojin stepped forward to help Li Xiao up. Fortunately, there was no blood, so it was not a big problem. It can only be said that there were too many gravels on the beach, and he deserved it if he was not careful.

Li Xiao didn't have time to think about Cheng Yaojin, instead he took the stool and thought of something.

The stool is very simple. The stool surface is made of a wooden board. In order to firmly insert the stool legs into the ground, a triangle is sawed off with a wooden board, and then nailed to the stool surface, so that the four sharp corners of the bench can be inserted into the ground well. , Prevent falling on uneven ground!
Seeing Li Xiao's silence for a long time, Master Yang knew that the famous Lord Li was not recruiting now, "There is no other way, why make things difficult for our Ministry of Industry? If it will affect the evaporation, let’s put it in the sun for a few more days!”

"It's all a small problem, why bother to dig into a dead end"

"There is a solution, Mr. Yang, you still have to rely on your brain to work!"

Li Xiao held the stool and raised his hand.

Back then, the Hongqi Canal was built on the Taihang Mountains. Was it because there were no precision instruments?

But the Hongqi Canal is more than 70 kilometers long, and the water level difference is only a little over 14 meters. What is this concept?This is the eighth wonder of the world!

What is it that made such a great contribution?
That's right, the small bench in front of you, with its face down, is placed in the water basin, using the triangular recesses of the two stool legs, two points and one line, you can immediately find the distant point!
"Just the bench?"

Master Yang looked at Li Xiao as if he had lost his mind!His mouth was full of ridicule, "Immortal Master Lu Ban never said that the bench can also be used for measuring! My lord, you are so merciful, tell me how to use it?"

Following Li Xiao's explanation, Master Yang's eyes gradually lit up!

The slap in the face came so quickly, it was almost unprepared.

Master Yang always blushed, timid and cowardly.

Li Xiao didn't make things difficult for him either, after all, he was five or sixty years old, so there was no need.

"Uncle Cheng, the method has been handed over to Mr. Yang, and the rest is the actual operation."

"The evaporation pool is mainly to prevent leakage. It must be done properly. Use a horse to pull the roller and grind it hard. Sharpen the knife and chop the firewood. Don't worry!"

"I know, I know, you've said it countless times!"

Cheng Yaojin waved his hand helplessly.

That being the case, then Li Xiao didn't bother to take care of it, it was easy to do less work.

The blueprints and procedures given by Li Xiao are not the ones used in the Dongfeng Salt Works of later generations, where seawater is injected once, dried for a year, and finally harvested.

Instead, the first level of water storage evaporates, and after the salt concentration increases, the solution is introduced into the next level of salt pan, and so on, until finally it is crystallized and harvested in the salt pan.

The advantage is that the cycle is short and the salt is produced quickly, but the disadvantage is that the output is not as huge as that of the later generations who can harvest a thousand catties per acre!

If Li Shimin wants to be fast, then he can only satisfy him!

There are many processes for drying salt, but it is not complicated if it is explained thoroughly. Now Cheng Yaojin has made a bad move, making his subordinates drink salt water every day!

With different concentrations of salt water, Lao Cheng vowed to train a group of masters who can accurately grasp the concentration of the salt field solution in the shortest time!

This is hard for those soldiers.

At the very beginning, I heard that there was salt water to drink every day, so I was so excited, I was so excited when I signed up!

Because salt itself is a precious thing, no big soldier has tried it, what does it feel like to eat salt casually.

Now that he drank salt water every day, his face turned green. After several people developed edema, Li Xiao immediately stopped this inhumane experiment!

But the soldiers were determined to complete the tasks arranged by Lu Guogong.

"Are you stupid? Can't you dip some chopsticks in each sample? Do you have to drink water like a cow?"

Now the soldier was enlightened, and the careful experiment did not cause any danger to his life!

It's rare for Li Xiao to rest in the yard. It's been a few days since the beginning of spring, and the sun is pretty good these days.

Basking in the long-lost sun, Li Xiao gradually fell asleep under Xiao Cui's shoulder pinching service.

Five miles outside Banqiao Town, Cheng Chumo and his party were in a hurry, but were stopped by soldiers!

"stop!"

The soldiers stepped forward quickly, with their knives out of their sheaths and their guns at their throats. There were still branches shaking at the cordon, and through the bushes, they could still see the flickering crossbow arrows.

Dozens of people were surrounded, and Cheng Chumo raised his hand and shouted loudly, "I am Cheng Chumo, the eldest son of Duke Lu! Don't do anything, don't do anything!"

No wonder Cheng Chu was silent, but from the corner of his eye, he saw no less than ten ambushes, and where else did he not see them?At this time, if you show off your abilities, you will only end up becoming a hornet's nest!

"General Cheng's son?"
