In the side hall, there were only a few people standing aside, watching Wang Zhi busy, and even the guards were kicked out.
"Haha, boy Wang, I'll light the fire for you."
Cheng Yaojin was laughing and joking, and shamelessly followed him.
The witnesses and physical evidence were all there, and Cheng Yaojin was also worried about Wang Zhi.
Although he would not be beheaded, he was afraid that the title he had just obtained would be lost.
Who would have thought that Wang Zhi would make a huge comeback.
As long as what Wang Zhi said was true, all the disadvantages would be wiped out, and he would even have great achievements.
Cheng Yaojin felt uneasy after all.
Even if he was scolded by Li Er a few times, he still wanted to come over and take a look.
Wang Zhi has naturally done it many times for the purification of coarse salt, and he is very familiar with it, even among several big bosses.
The coarse salt that Li Er ordered was indeed thick enough, with pieces bigger than a fist, some yellow, and some light green.
Wang Zhi put them directly in the pot and started boiling them, otherwise they would just dissolve them in water.
If you open it, it will take a long time.
"Here, Uncle Niu, come and help me."
After heating, the coarse salt melted quickly, but the water was turbid and even a little red.
I didn't know what kind of mineral was responsible.
Wang Zhi asked Niu Jinda to hold several layers of silk stacked together and cover it on a porcelain pot.
Then Wang Zhi held the pot and carefully poured the solution in little by little.
Wang Zhi poured the tea very slowly, as long as it took a cup of tea.
However, there were a lot of impurities left on the silk, including pebbles, gravel, and soil.
The solution in the porcelain jar below is not so turbid.
After repeating this several times, the solution became clearer and clearer, and the color became less red.
The iron funnel Wang Zhi had prepared before bringing it over was similar to a small funnel, just a large one, and then filled with large pieces of charcoal.
With the obstruction of charcoal, the speed of the solution flowing down is naturally much slower, and many impurities and the like are also blocked.
Therefore, Wang Zhi did not dump it this time, but found a large spoon and scooped it in one spoon at a time.
This process is naturally very slow because there is no rush.
The solution dripped little by little and turned into light blue, and Wang Zhi knew that it was done.
It took about half an hour before the solution in the large pot was completely dripped.
Wang Zhi poured the light cyan solution below into a clean pot and placed it again on the stove.
"Uncle Cheng, the fire is boiling.
I'm sorry to bother you."
Just boil the salt water, and then the water slowly evaporates, and what's left is naturally the best green salt.
"Okay, let's take a look at mine."
Cheng Yaojin saw Wang Zhi's meticulous behavior, and his confidence in Wang Zhi increased.
"Okay, okay, Uncle Cheng, don't be so angry, just a little bit of anger will be enough."
Seeing that the water in the pot was getting less and less, Wang Zhi quickly asked Cheng Yaojin to take out most of the fire stick, even if it was too hot.
"Your Majesty, please look, this is about to crystallize.
These crystal particles are green salt."
Wang Zhi pointed to the bottom of the pot that had begun to crystallize.
The layer of white crystals was white and shiny.
"Wow haha, Your Majesty, let me, Old Cheng, have a taste first."
As he spoke, Cheng Yaojin took off a piece, first smacked it with his hands, and then held it in his mouth.
Although it was so salty, he still ate it.
"Come here, bring me a bowl of water."
Li Er felt inexplicably when he saw Cheng Yao Jin Xian twitching.

Although this old guy is always angry with himself and often does some stupid things, he is so loyal.
Then Li Er, Niu Jinda, Chang Sun Wuji, Wei Zheng and others all took off a small piece, looked at it carefully, and then put it in their mouths to taste it.
"Your Majesty, this is the best green salt.
This method is wonderful.
From now on, our Tang Dynasty has no shortage of salt."
Changsun Wuji smiled and looked at Wang Zhi much more favorably.
He was such a clever young man.
Military generals like Cheng Yaojin and Niu Jinda were even more delighted.
They almost ran out of salt on many expeditions, but eating salt from those salt mines caused more troubles.
Diarrhea was a trivial matter, and even It will still endanger lives.
Now it is better.
With this green salt, it will be more convenient when there is a war in the future.
"Wang Zhi, this thing you invented is exquisite and has made great contributions to the country.
What reward do you want?"
Li Er has always been clear about rewards and punishments, which is one of the reasons why the princes and ministers were convinced.
"With this method, the production of salt will definitely increase greatly in the future.
I also hope that the court will lower the price of salt so that the people can buy cheaper salt."
Wang Zhi's title didn't last long, so he didn't plan to ask for any reward.
"What a great job of letting the common people eat cheaper salt.
Please give me my respect."
Wei Zheng didn't expect Wang Zhi to say that, so he straightened his clothes and bowed to Wang Zhi.
"Wei Gong has broken a young man, so I don't dare to accept it."
Wang Zhi quickly supported Wei Zheng, but he couldn't let old man Wei bow to him and his life would be shortened.
"Although you don't want it, I can't help but reward it.
Think about it carefully.
I want to set an example for everyone in the world.
As long as it is good for the country and the country, I will not hesitate to reward you."
Li Er looked at the young man in front of him and liked him very much.
At such a young age, he not only had military exploits, he could also always make some strange-looking things, but they were of great use, such as the previous barrel cart. kind.
"Well, Your Majesty, let me make a small request.
If I make any mistakes in the future, I hope that Your Majesty will come to me alone and don't hurt my family."
Thinking about what happened between him and Yu Zhang, Wang Zhi felt that Li Er might be furious after knowing about it.
At that time, Li Er lost his mind and didn't know what he would do.
It was better to take insurance first.
"You still want to rebel, little bastard."
Before Wang Zhi could finish speaking, Niu Jinda slapped him.
Li Er's treatment of the heroes was indeed generous.
There was no cunning rabbit or lackey, and even Li Jing, who had great achievements and shocked the master, was just at home, without any worries about his life.
Therefore, the ministers also support Li Er.
As long as they do not rebel, as a meritorious minister, their lives will naturally be worry-free.
"Haha, okay, I promise you."
Li Er thought that Wang Zhi said this because he had a grudge against Hou Jun, so he just smiled and agreed.
Even Changsun Wuji and others were stroking their beards and smiling.
Only Cheng Yaojin looked at Wang Zhi's figure thoughtfully.
It seemed that this was not the case.

"It's bad, Your Majesty, the ministers are still waiting in the main hall.
Should we go back first?"
Changsun Wuji secretly shouted, "It's a big meeting today.
It's rare for so many officials to be waiting."
After that, Li Er came to his senses and walked directly towards the main hall without replying, with Chang Sun Wuji and others following closely behind.
"Duan Hong, take the green salt and the iron pot to the main hall, and don't expose the unused coarse salt, silk, charcoal and other equipment."
The method is practical, but also simple.
Li Er doesn’t want too many people to know about it.
"The Hou Wangzhi of Lantian County has developed a new method of making salt, which is simple and practical, and has contributed to the country.
He is specially rewarded with two thousand acres of fertile land, thirty kilograms of gold, and ten pieces of fine silk Shu brocade":
