Before leaving, Ma Chao didn't worry about political affairs at all.
He has three masterminds in literature: Jia Xu, Fazheng, and Yang Fu; he has the famous general Pang De in military affairs; and he also has Brother Chou secretly cooperating with him.
Even the two major forces, Dongqiang and Shenbumen, relied on him.
It wasn't a disaster like thunder that severely damaged the Ma family.
And the only source that can create this disaster is Chang'an.
Ma Chao's entry into Chang'an as the head of the Ma family was a turmoil for the Ma family, and it was also a turmoil for the Chang'an court.
His visit to Chang'an was not so much about entering the court as a pledge, but rather a necessary process for Ma Jiazhan: only by letting the Chang'an court turn its attention to Ma Chao alone could the forces behind Ma Chao have a period of calm development. .
Therefore, whether it is from the perspective of family hatred or national hatred, Ma Chao's entry into Chang'an is inevitable.
Before he left, the things that worried him the most were actually the things that had changed because of him.
For example, new crops, tea-frying technology, distilled liquor, steel filling method, improved papermaking technology, etc.
Fortunately, these new things have now reached a large scale in Fufeng, and there are dedicated people in charge of taking care of them, so Ma Chao feels more at ease.
But there was only one thing that he couldn't forget, which was whether the craftsmen in the arsenal could completely master the salt purification technology.
Before leaving, Ma Chao specially called the three giants of the arsenal: Han Feng, Zheng Hun, and Pu Yuan, and demonstrated to them the salt purification technology step by step.
In fact, the salt purification technology is very simple.
It is nothing more than a few steps: dissolution, filtration, detoxification, and evaporation and crystallization.
In Ma Chao's view, this is a small technological experiment, but for the three giants, this is another milestone technology.
Especially Han Feng, who also knew the huge profits behind the salt purification, used Ma Chao's name to mobilize 200 of Ma Chao's personal guards to stand guard at the arsenal, acting as nervously as if Ma Chao was making gunpowder.
The arsenal has everything.
Ma Chao gave an order, hammers, iron drills, salt sieves, linen cloth, charcoal, wooden barrels, iron pots, and even five hand-cranked stone mills.
Ma Chao checked it over and found that everything he needed was quite a lot.
"Watch it.
Your master is now delicate and expensive, so using it once is a big deal."
Ma Chao said with a smile.
He took a small hammer and carefully smashed a few salt stones into small pieces.
He called a guard and poured the salt into the eye of the stone mill.
The guard then shook the stone mill and started to spin it.
The brown salt powder slowly rolled from the edge of the stone mill.
When it flows out, Ma Chao collects the salt and stone powder into the wooden barrel and adds water.
Stir with a wooden stick to fully melt the salt into the water.
When the solution is saturated, he said: "This is the first step, dissolution.
Crush the salt block and pour it into the bucket."
Then, Ma Chao poured the solution into another wooden barrel covered with a double layer of linen.
After a while, the linen was covered with gray-black slag.
Remove the linen and the solution in the bucket turns brown.
At this time, the color of the solution became lighter, but there were still many impurities.
So another wooden barrel was covered with four layers of linen, and after filtering again, a light red solution was left.
Ma Chao saw that the impurities had been filtered out.
Describe the key points of this process: "This is called filtration.
No matter how many times you filter it, the filtration is not complete until the color of the solution turns into this light red."
At this time, it still cannot be steamed and purified, but the detoxification stage should continue.
Ma Chao took a huge funnel and ordered the guards to smash the charcoal.
Before the guards could do anything, Han Feng, Pu Yuan, and Zheng Hun came on the scene in person and smashed the charcoal first.
Ma Chao used four layers of charcoal particles to crush the charcoal.
Wrap the linen cloth and stuff it into the funnel, squeeze it tightly, and look for I built a shelf, fixed the funnel on the shelf, and poured the solution into the funnel.
After a while, the light blue solution slowly flowed out.

Take a handful and taste it.
Yes, it only tastes salty, not bitter.
Although it was lost in the process Some salt, but make sure the salt you cook is definitely edible.
"This process is the most critical step.
Although some salt may be lost during this period, I would like to warn everyone that anyone who sells salt without going through this step will not be blamed for military law."
At that time, Ma Chao looked extremely solemn.
After all, this is a major matter related to the health of Ma's store and the entire Han people.
"Lord, the charcoal used here can be any kind of charcoal."
Han Feng also knew that this link was crucial, so he asked this very high-level question.
"Well, ordinary charcoal is not available, but bamboo charcoal is best.
Bamboo charcoal has stronger adsorption capacity."
Ma Chao nodded, very satisfied with Han Feng's to-the-point question.
Afterwards, when it was hot, Ma Chao ordered his guards to set up an iron pot and pour the solution into the pot to boil.
But he stayed far away from the iron pot: It's hot in summer, it's easy to get some salt.
Watching the solution bubbling in the pot, Ma Chao felt uneasy.
After all, this knowledge was taught in junior high school chemistry.
But whether it can be done or not remains to be seen.
After the water in the pot gradually evaporated, Ma Chao saw a thick layer of cyan crust left on the bottom of the pot.
He removed the firewood, broke off a piece from the pot and kept it in his mouth: "Well, the taste of pure salt, not bad" Without waiting for Ma Chao's instructions, Zheng Hun and Pu Yuan had already taken off a large piece of their fingernails and stuffed it into their mouths.
Although Xian's face was twitching, they were reluctant to vomit.
Seeing Ma Chao's signal, the other guards swarmed towards the iron pot, picked off a piece and started eating.
After putting it in his mouth, a few of the guards were so salty that they shed tears.
They all knelt down in front of Ma Chao and shouted: "My lord is really a god."
The god-ass Ma Chao disagreed: He had just estimated that the smashed salt block weighed ten kilograms, but in the end only about three kilograms of refined salt was boiled out.
This loss was really too great.
However, Ma Chao also knows that this is unavoidable: it is much better than people relying on luck to eat salt blocks.
Besides, China has been in China for thousands of years, and until the population reached more than one billion in the later period, there was no chance of it happening.
All the salt was gone.
I might reach the beach by then.
Making salt at that time is not about getting as much salt as you want.
Thinking of this, Ma Chao ordered Han Feng, Zheng Hun, and Pu Yuan: "You three, put all the research on hand recently and devote yourself to the production of this salt purification tool.
After Meng Ta and Hanzhong reach an agreement, , Just carry out large-scale mass production.
As for shipments, it is absolutely right to leave it to Meng Da, who is now obsessed with money."
"My lord is wise" The three of them clasped their fists and were very convinced of Ma Chao's arrangement.
"By the way, bring these samples to Meng Da and ask him to give a price."
Ma Chao clapped his hands and said, "Are those things ready?"
"Don't worry, my lord, the glass happened to be blown yesterday and has been carefully packed into the box.
At your request, a lot of fur, silk and linen were specially added to prevent shock."
Han Feng knew what Ma Chao was asking and stepped forward to answer.
"Well, yes, the Ma family has an arsenal, which can support at least a hundred thousand troops."
Ma Chao was filled with emotion: Sure enough, technology is the primary productive force.
No matter what era, the most scarce thing is talent.
"Those are just colored glasses.
I will tell you how to make colorless glass after I come back from Chang'an."
Ma Chao said as he mounted the elephant dragon horse and was about to rush back to his backyard.

As if he remembered something again, he warned: " Remember, the glass-making method is the biggest secret of the Ma family, so you must keep it secret.
Also, don’t produce too many glass products, just ten pieces a month.”
When "Nuo" saw Ma Chao running away, Han Feng, Zheng Hun, and Pu Yuan couldn't help but wonder: Could it be that the lord has really descended from the sky to this earth?
How come he can do all kinds of incredible things:
