These days, Li Mu has led several craftsmen to try out soda ash with miscanthus salt.
The miscanthus nitrate is purified, and then calcined to produce flavour.
The flavone is then reacted with quicklime to obtain sodium carbonate.
After several times of purification, the purity of sodium carbonate obtained is already very high.
After having soda ash, soda ash solution and lime are used as raw materials to make causticizing reactions occur, and caustic soda solution and caustic mud precipitate are obtained.
After filtration to remove insoluble substances such as caustic mud precipitation, the solution is evaporated to obtain liquid caustic soda and solid caustic soda.
Caustic mud can be used as a raw material for cement after washing.
After successfully making caustic soda, Li Mu asked people to find lard and pour it into a pot with a predetermined recipe to heat and stir.
During the stirring process, a small amount of water is added to replenish the evaporated water.
Stop heating only when the surface of the mixture is no longer floating.
Then add salt water to the pot while it is hot, stir it thoroughly, and let it cool to allow some debris particles to precipitate out of the mixture.
Finally, the debris particles were removed and soap and glycerin were obtained.
After the trial, he felt that the detergency was good, so Li Mu ordered the craftsmen to mass-produce soap according to this method.
At the same time, various spices are added at the end of the process, and various shapes are customized with molds.
The produced appendage glycerin was purified by Li Mu and all sealed up.
Li Mu selected 100 exquisite and capable people from the farmers in the village, went to the streets and alleys of Chang'an City and the east and west cities, carried a cart of soap for publicity, free trial and giveaway, and put up posters, saying that in three days, it would be sold in the east and west cities.
Three days later, when a large number of this unprecedented soap appeared in the east and west cities of Chang'an City, it was instantly snapped up.
So the Tang Dynasty and foreign merchants who came to hear the wind used the deposit to set the output of the workshop for the next year.
Li Mu set two prices for soap.
One is a translucent soap used by ordinary people without adding spices, priced at 20 yuan a piece, which can be used by a family for half a month; The other is a delicately made soap for high-ranking officials and nobles, priced as high as 200 yuan a piece, but it will be used up after a few baths.
As for the cost of soap, the first type of soap is only about a penny, and the latter is only ten cents, mainly because the spices of the Tang Dynasty are really expensive, which raises the cost.
But even so, the profits of the two kinds of soap have reached an unprecedented height, more than 20 times the profits, the key is that no one has collected taxes from themselves, and it is difficult not to get rich.
Although the supply exceeded demand, Li Mu still squeezed out some soap and used it to give away.
In Chang'an City, all officials above the fifth grade sent a box of twenty pieces of soap, and the eldest grandson Wuji, Fang Xuanling and other important ministers of the imperial court sent two boxes.
This is not only to connect feelings, but also to advertise soaps.
Top-down promotion is often the fastest, the so-called upward and downward effect, the poor always like to learn the rich people's lifestyle.
And Li Mu himself was entering the palace with ten boxes of soap, with a few iron-shelled heavenly thunderbolts newly produced.
At this time, the heavenly thunder was already very close to the grenades of later generations.
The wooden handle and iron shell, pulling the string to ignite the fire, but the iron head medicine department has been more than doubled.
There is no way to do this, the power of black powder is insufficient, and it can only be compensated for by quantity.
The weight of this grenade is naturally much larger than the grenades of later generations, fortunately, the manpower of this era is obviously greater than that of later generations, three or four pounds of grenades, stunned can throw more than 80 steps, and if you try it yourself, you can throw about 40 steps at most.
Li Mu found that the people of this era were generally more powerful than the people of later generations, and the reason why he ate more was that Li Mu had already developed a deep fear of the amount of food for the five hundred guards.
No matter how much money you make, you can't satisfy this group of big stomachs.
But fortunately, the mass production of soap has made the accessory pork officially a standard recipe for the guards, and Li Mu no longer has to buy a large amount of expensive mutton for the guards, which has reduced the daily cost by more than half.
But the problem is that the pigs around Chang'an have rapidly seen a low price, and the price of pigs has risen rapidly, a month has risen by three percent, Li Mu had to send people to a farther place to purchase pigs, and build hundreds of acres of pig farms on the back of Zhuangzi Mountain, the clay in that place was gradually dug away, leaving a bigger and bigger pit, Li Mu did not even let people back to the soil, but directly leveled, divided out a pig house, began large-scale pig breeding.
Fortunately, the people of Chang'an saw that the price of pigs had skyrocketed and was profitable, so they began to open a pigsty at home and raise a few pigs to supplement the family.
The so-called double the profit, the businessmen will take the risk; If there is a double profit, the merchants will flout the law; If there is a triple profit, then the merchants will trample on everything in the world The shops in Chang'an City have learned to be obedient, and all the raw materials that Lijiazhuang wants to purchase are changing the price increase.
Li Mu had to purchase the corresponding raw materials from further afield in order to reduce costs. 。
After the rumor, Li Mu met Li Shimin in the Chengqing Palace.
Li Shimin was angry, he "snapped" the fold in his hand on the case, and shouted angrily: "Who let him do this, the lives of tens of thousands of soldiers were cut off by him in Yehu Gorge, you talk about it, talk about it, how to deal with it" All the ministers in the palace were terrified, and no one could have imagined that when the overall situation of the battle of Tuyuhun had been decided, there would be such a big fork.
In this battle, tens of thousands of troops were wiped out, and if they died on the battlefield of the conquest of Tuyuhun, it would always be reasonable, but now they are dying in vain.
No one wants to make a head rafter and provoke Li Shimin's anger.
For a moment, there was silence in the temple.
And Li Mu walked in at this time, it was really not the right time.
Li Shimin saw Li Mu who was looking around at a glance, and scolded: "They are all five-grade lords, and they don't know how to understand the rules." ” Li Mu hurriedly saluted and said, "Erchen has seen the emperor. ” Li Shimin frowned and said: "I heard that you have made something happen in the past few days, which has made the chickens and dogs jump in the market."

"Ahem."
Li Mu coughed dryly, what is this called, we are an invention and creation, and it is good to work for the benefit of the people of the world "Back to the emperor, the retainers made things called soap."
When the ministers in the hall heard this, they smiled at Li Mu with understanding.
Li Shimin asked coldly: "Don't do business, mess around every day."
Tell me what to do."
Li Mumai smiled obediently: "The emperor has wronged his sons, this time when he entered the palace, his sons brought good things." ” Li Shimin restrained his coldness and asked lightly: "If it weren't for the soap you said?"
Li Mu replied: "There is also soap, mainly for the emperor, the queen mother and the imperial concubines. ” Li Shimin grabbed the white and said: "Since I don't have my share, I still come to see what I do."
"Yes, yes, how could the sons forget the emperor?"
Li Shimin stopped pestering and asked, "I'm busy."
Tell me what it is."
Li Mu made an explosive gesture with both hands, gave Li Shimin another look, and said, "Please take a look." ” Li Shimin saw that he understood his heart, and said to the ministers in the palace: "You love Qing and take a short break, I will come when I go, and the auxiliary machine and Xuanling will go with me." ” "Yes."
Fang Xuanling and the eldest grandson Wuji responded in unison.
Leaving a group of inexplicable ministers, Li Shimin and his party went to the test site again last time.
A few sheep were also brought in and a few pieces of armor were placed.
After arranging it, Li Mu asked people to take the box brought into the palace, took out a grenade from it, pointed it to Li Shimin, and said: "Your Majesty, this time the ministers have improved the three problems at the same time.
First of all, a wooden handle is set up, which can be easily held and at the same time increase the throwing distance. ” Li Shimin and the eldest grandson Wuji and Fang Xuanling came close to watch.
Li Shimin asked, "How far can you throw now?"
” Li Mu replied: "Originally, in Liangzhou, it was about forty or fifty steps to throw, but now the guards in Erchen Village can throw eighty steps or even farther. ” Li Shimin nodded and said, "Okay, continue to talk." ” Li Mu said: "Then the gunpowder filling equipment has been improved, from clay pots to pig iron shells, and when casting iron shells, several vertical and horizontal grooves have been opened, so that once it explodes, the iron shell will be broken into dozens of small iron pieces and fly in all directions to enhance lethality."
At the same time, the gunpowder filled in the iron shell was pressed into a cylindrical shape, wrapped in pig intestines and pancreas, and then coated with grease, and the fire paint was poured into the fit to prevent water and moisture. ” Li Shimin asked: "How long can it be stored?"
Li Mu replied: "Under normal circumstances, it should not be a problem to store it for two or three years. ” "Well done."
Li Shimin nodded in praise.
Li Mu continued: "In the end, Erchen placed flint in the wooden handle to draw the line to ignite the fire, so as to avoid the trouble of carrying torches and lighting the fire every time the throwing soldier was avoided, so as to reduce the interval between each throw, please stay away from the emperor and watch the Erchen throw." ” As he spoke, when Li Shimin and the others walked back to a safe distance, Li Mu opened the lid of the wooden handle, pulled out a thin hemp rope from the handle, and pulled it hard, only to see a puff of white smoke coming out.
Li Mu threw the grenade at the target area with all his might, and hurriedly lay on the ground.
Only after hearing an earth-shattering loud noise, Li Mu got up from the ground, patted the dust on his body, and looked at Li Shimin and the others.
Li Shimin and the three of them were already stunned, they looked at each other, they saw an explosion last time, but the sound was far less loud than today's, and the shock was much smaller, the only thing that was not as good as last time was that the black smoke this time was much smaller than last time.
But the lethality of this time is far from being comparable to the last time.
In the area of the explosion, they saw that even the heavy armor had been blown ten paces away, and some small pieces of iron were nailed to the armor, and more were piercing the armor nails through small holes.
And those sheep that were jumping around had long been torn into pieces, and they were all over the ground.
The three of them exclaimed in their hearts, what kind of weapon was this, with it, even a powerless person could kill a group of battle-hardened soldiers in an instant.
In addition to Li Shimin, the eldest grandson Wuji and Fang Xuanling looked at Li Mu with a little strange eyes
