"Holy Lord, can volcanic mortar be used to make city walls?" Luo Shixin, who circled around the unhardened cement slab, asked.

Yang Tong frowned and said: "The volcanic ash mud is called a mess, and it will be called cement in the future, which is simple and trouble-free." ”

"Whoa." And they obeyed, and took the name to heart.

"Cement can be hardened into stone in water, so it's easy to build a city." Yang Tong answered Luo Shixin's question just now, and then said: "It's just that cement is a natural volcanic ash, no need to take local materials, in order to build a city, specially transported from thousands of miles away, costing countless manpower, financial and material resources, the key is that this thing is too little after all, a little less when used, and it is purely overkill to build a city, it is really unnecessary." ”

"The Admiral understands." Luo Shixin was right when he thought about it, just in terms of the strength of the city, the current materials are already very good.

Yang Tong pondered for a moment and said to Jiang Xingben: "I remember that there seem to be volcanoes in the Yanshan Mountains and Changbai Mountains. ”

"What the Holy One says is true." Jiang Xingben said, "This is the volcanic stone from Yanshan, which enters Wuhai through wet water, enters the Yellow River and Guangtong Canal by sea, and finally arrives here." ”

Yang Tong nodded and said, "Collect more volcanic ash and volcanic stones to Luoyang to prepare for Li Shilang to build a bridge." ”

"Whoa." Jiang Xingben bowed.

"The cement slab won't be able to dry for a while, let's go to the Shaofu Supervisor to have a look."

The Shaofu Supervisor was in charge of all the skills of the hundred crafts, including the art of smelting and forging, and there were the best craftsmen of the Great Sui. Many weapons and equipment are designed by the Kaitian Academy, and then built by the Shaofu Supervisor, although Daxing is not the national capital, but also set up a branch, this is Yang Tong imitated Shen Fei, Cheng Fei, hope that the Kaitian Yuan and the Shaofu Prison on both sides of the competition to use their brains to create more advanced weapons and equipment and utensils.

There are more than a dozen large stoves in the greenhouse in the backyard of the Shaofu Prison, the fire is burning, someone is pouring water into it, and when I ask, I know that it is planned to use different water temperatures to quench the mold knife, hoping to optimize the sword, and there is even a large pot of warm lard, which is also something that craftsmen use to carry out experiments.

Although I don't know if lard can optimize swords, for Yang Tong, who came from the era of handmade soap, he knows that animal oil can be used to make soap and soap.

Yang Tong remembered the black liquid he used in the bath, and suddenly moved the idea of making a pot of soap, so he asked people to pour caustic soda into it, and then kept stirring, and a strange smell suddenly wafted in the pot. When the oil pan is boiling, have the cauldron remove from the stove and continue stirring. Until the lard caustic is completely combined, add a small amount of brine while hot

Then, the curious minister of civil and military affairs was shocked by the vision in the pot, only because the oil pot had undergone unexpected changes, and some ointment-like pale yellow substances appeared in the pot out of thin air.

The temperature of the oil gradually decreased with continuous stirring, the pale yellow substance cooled and hardened, floating on the upper layer, Luo Shixin snatched a large spatula in the hands of a craftsman, and according to Yang Tong's instructions, happily scraped off the layer of substance, poured it into the prepared iron basin, as long as it was naturally dried, it was a big piece of soap. But the soap made in this way is of poor quality, and maybe it smells of lard.

"Is this wax?" Yang Gongren asked in surprise.

Yang Tong looked at the turbid soap in the pot and the waste liquid at the bottom, his heart moved, and he said with a smile: "The wax is still in the pot, and this is a crude soap, which is cleaner than soap for washing, bathing, and washing hair, and further processing will become fragrant soap." ”

Yang Gongren asked again: "Can this soap be used now?" ”

"The soap has to be hardened before it can be used, and it takes a long time, longer than the cement board, and of course it can be hardened forcibly, but for now, it is better to change the wax first." Yang Tong said.

"How did it change? Holy Heaven, you say, I'll do it. Luo Shixin waved his hand excitedly to listen to the spatula, and the expressions of the others were the same as him, eager to try, even Li Jing, an old man.

Man!

They all have an extraordinary interest in experimentation.

Yang Tong said, "Get some brine." ”

"......" Many civil and military officers looked at each other, they killed people and calculated, how do they know this? And generals like Luo Shixin and Wei Chigong don't even know the location of the young superintendent.

"I'll look for it!" It was still a craftsman who flew away.

Yang Tong said speechlessly: "I haven't finished talking yet." ”

"Whatever else is needed by the Holy One, it is the same as taking it from the lowly position." Another craftsman said.

Everyone admires this miraculous emperor so much, and he can always use familiar and inconspicuous things to conjure up something magical and unheard of.

"Make a filter."

This thing is very simple, first wash the pebbles, fine sand, and charcoal of different sizes, and then ask the craftsman to take out an iron bucket with a bamboo pipe, first spread a layer of cotton cloth on the bottom, put a layer of large charcoal, and then spread a layer of cloth, a layer of small charcoal, and then a layer of fine sand, small pebbles, and large pebbles, so that five or six layers occupy most of the iron bucket, and a simple filter is completed. As soon as the liquid is poured into the bucket, the liquid that has been filtered will flow out of the bamboo tube.

The filter was ready, and the craftsman who went to find the brine also came back with a bucket of brine.

Seeing that it was ready, Yang Tong asked Yang Tong to scrape the turbid things in the cauldron into a wooden basin, which was not fully reacted lard and soap, as well as some other impurities.

Then let the brine be mixed into a basin and stirred together.

After a short time, the contents of the basin gradually solidified.

This is a series of crafts he learned by making handmade soap when he was bored before, lard and caustic soda, and the soap was obtained after the reaction; When hydrochloric acid is added, the candle is formed.

When the wax had not hardened, Yang Tong asked someone to take a piece of cotton thread, bury it in a basin with a wooden pole, and light it.

The large pot of candles was still bright in broad daylight, and there was almost no smoke from the oil lamp!

"Oh my God! Candles are so simple. It is lower than the cost of butter wax, and it is bright and less smoky, so if you sell it to the supply and marketing cooperative, you will definitely be able to make a profit! ”

Yang Shidao and Ling Jing, the two big housekeepers in charge of money, glanced at each other, and they both saw coins in each other's eyes.

Candles are a luxury in this era, and the candles used in the palace are made of substances secreted by ash worms, or beeswax, these two kinds of candles are extremely expensive, in addition to these two, the butter wax that appears in the classics from time to time is also made of good oil, and it is too expensive to enter with it. And the lighting used by ordinary people is generally a bean-sized vegetable oil lamp!

This lard wax has a low cost and shines far more than an oil lamp, and he will be popular all over the world!

"What is this, there is still in the pot." Yang Tong's words are true, just because there is still glycerin in the waste liquid!

"And??" Everyone's eyes almost fell off, and after getting along for several years, they thought they knew this amazing emperor very well.

Anyway, it's just the tip of the iceberg.

Always inadvertently, unexpectedly again and again.

In the astonishment of everyone, Yang Tong instructed the craftsman to lift the cauldron and slowly pour the smelly pale yellow liquid into another large basin, not knowing what the use of this stinky water was. After that, the stinky water was poured into the filter, and the thin tube at the bottom of the bucket slowly flowed out of the clear and transparent water, instead of the dirty and foul-smelling stinky water, which once again subverted people's subjective assumptions.

"It's amazing, but what's the use of this water?" One or two admired Yang Tong's means of turning decay into magic.

"As we all know, wine, peach wine, and fruit wine are bitter and astringent at the beginning of fermentation, and it is extremely unpleasant to drink, and it takes a long time to slowly fade away, but if the altar is not sealed firmly, or the light, temperature, humidity and other factors are not right, this wine will almost be wasted......" Yang Tong looked at Wei Zheng and said with a smile: "Wei Shangshu's winemaking skills are very high, and your wine is full of color and aroma, not weaker than the wine of the Western Regions... You should know that..."

Wei Zheng bowed slightly: "That's true." ”

Yang Tong pointed to the glycerin that was still flowing out and said: "This is called glycerin, which has a different sweetness from grapes, which can not only effectively remove the bitter taste in the wine, but also improve the quality and taste of grapes, peaches and other fruit wines, which is the best auxiliary to make fruit wine, so that your wine does not have to work so hard, you can get the wine you need." ”

Everyone was shocked and surprised.

A pot of lard was tossed and turned by Yang Tong, and it was incredible that so many tricks were tossed! Could it be that the saint is really an immortal, otherwise why does he know all kinds of knowledge?

"Is that true?" Wei Zheng wanted to say whether he believed it or not, but Yang Tong's pot of lard really made him unable to believe it.

"It's true." Yang Tong said to Luo Shixin: "Xiao Luo, you take a few soldiers to the West Market to buy a few jars of bitter, astringent and sour bad wine, grapes and peaches each come with ten jars. ”

There is no such bad wine in the palace, so you can only buy it.

"Whoa." Luo Shixin saluted and ran out in high spirits.

"Mingyue, you go to the Guanglu Temple Zhensha Department to get some milk, eggs, and some spices and pollen." Yang Tong ordered Yin Mingyue to follow to watch.

"Whoa!"

After Yin Mingyue left, Yang Tong once again asked people to make two transitioners for backup, and at the same time returned the filtered glycerin to the pot and re-boiled, with the purpose of evaporating the water in the glycerin.

Glycerin viscosity is higher than water, glycerin in the pot is boiled, the bubbles change from cheerful to thick, and pour out accurately.

It was more than half an hour later, and Luo Shixin and Wei Chigong had also returned.

Yang Tong asked people to pour ten parts of wine and peaches, one catty each, and he didn't know the best ratio, so he could only take a stupid way to add one catty, nine taels, and eight taels to the ten parts of wine...... One or two glycerins and a couple of egg whites in a hope of experimenting with the best ratio for the taste of the mouth.

After stirring thoroughly, strain one by one with a spare strainer. A red wine and a clear peach wine appeared. Just looking at the color, it is countless notches higher than the original liquor.

The next thing is naturally to let Wei Zheng, the brewmaster, taste them one by one.

"This thing really doesn't drink the dead, does it?" Yang Qinfang, this girl, has been hiding from Yang Tong for a long time, but she is active by nature, and when she heard that there was an experiment here, she ran over to watch it again, and when she saw Wei Zheng 'testing poison' by herself, she was worried about him.

"You can try it, it should taste good." Yang Tong said seriously, this wine will definitely not kill people, at most it is just diarrhea. Of course, Yang Tong himself would definitely not drink this kind of semi-finished product......

"I don't." Yang Qinfang wrinkled her pretty little face, revealing a disgusted expression.

Yang Tong smiled, a little sore in the head...... Since being lit by Cheng Cannon, this girl has been hiding from him for a long time, but when they met again, they seemed to get closer, and they could almost smell the faint fragrance on her body.

When Wei Zheng tasted the best one, Yang Tong mixed a lot of them and distributed them to everyone to taste, which surprised people who had tasted bitter, astringent and sour inferior wine, and they didn't expect that after adding this glycerin, the taste of the wine would change greatly.

If you collect all these bad liquors, add glycerin and sell them, you will definitely be able to add a lot of income, and you can also open up a way of wealth for the people, which can be said to kill two birds with one stone.

Finished wax, glycerin.

Go back and make soap, divide the soap that was taken out first, divide it into several points, and add milk, mung bean powder, lavender powder, chrysanthemum powder, ginseng powder, rouge powder, and He Shou Wu bitter tea powder...... Stir well, take it to the pot and heat it to make it saponified quickly, this step is called the heat method, which can make the water evaporate quickly, put it in the mold, and at most a week, the soap of various fragrances can be used. If you are not satisfied with this shape, you can also heat and liquefy it again and pour it into your favorite mold to harden.

Watching the craftsmen scoop all kinds of soap into various molds, Yang Tong, who took the lead in the experiment, had a deep sense of accomplishment, but also a great regret, because he was not engaged in chemical industry, and there were too few things to do, otherwise, he would definitely enrich the goods of Dasui.

But despite this, it also amazed everyone.

After all, no one would have thought that ordinary lard could be used to make soap, candles, and glycerin, which changes the taste of fruit wine.

Yang Tong engaged in this experiment, firstly, he saw the lard and was interested, and secondly, he hoped that through this experiment, the door of innovation of the craftsmen would be opened, and they would realize that many things that they were accustomed to could undergo unexpected changes.

。。。。。。。。

"Mr. Ouye, I need you to craft several weapons." Yang Tong said to a craftsman in his sixties.

This old man's name is Ou Yeqian, his hair is faintly gray, Xu is a craftsman, his body is very strong, look at his spiritual temperament, not like the sixty-year-old man at all, he is a famous craftsman, smelting technology can be called first-class, Yang Tong's Chaolu treasure knife and 'Shengwu 36 style' are forged by him personally, and since then he has been designing and building new weapons and armor, is the chief teacher of Daxing Kaitianyuan and Shaofu Supervisor. The idea of quenching the lard was his idea, but this cauldron had become Yang Dong's soap, candle and glycerin.

"Holy Lord, please command." Ou Yeqian heard Yang Tong's call and hurriedly walked out.

Yang Tong originally gave him the blueprints of the Chaolu Treasure Knife and the Thirty-six Styles of the Martial Saint, and many of the styles of these thirty-seven weapons were made by Yang Tong from online games, and there were some fancy things that were not practical, but after Ou Yeqian's transformation, they became real objects one by one, and in the process of improvement, Ou Yeqian was deeply inspired, such as the three-edged military thorn, blood groove and other ideas, and began to be used in some weapons.

"Yizhou Duoguan Mountain is dangerous, the road is narrow, the horizontal knife can not be used in some places, for example, the plank road is very narrow and dangerous, if the force is too strong, cut to the stone wall, the soldiers may be bounced off the cliff, and the dagger is too short, in the fight with the enemy, do not have an advantage. That's why I want to create a weapon that suits Yizhou, between a long soldier and a short blade. ”

Jiang Xingben had also suggested before that a complete set of weapons and equipment suitable for mountain warfare and jungle warfare should be designed for the Great Sui army, but to this day, except for non-slip boots, light armor, and climbing equipment, there has not been much improvement in weapons.

"Jiang Shangshu also mentioned this problem, but the weapons designed by the humble position have certain flaws." After Ou Yeqian finished speaking, he asked people to take out a miniature version of the horizontal knife, and continued to introduce: "This is a short blade designed by the humble rank according to the characteristics of the Holy Chaolu Treasure Knife, Horizontal Knife, and Miao Knife, and the blood groove of the military thorn. When the soldiers in the hands of the horizontal knife, Miao knife because of the terrain and close to the inconvenient use, this knife has become the leading weapon in close quarters, when using this knife, even people with knives are facing the enemy, all cover with a barrier body (obstacle knife + body) to resist the enemy said, obstacles, hidden people also. ”

"It's called a barrier?" Yang Tong asked with a smile.

Qian Yeqian said: "Exactly. ”

Yang Tong waved a few times, carefully felt the short-bladed killing technique, thought about it, and let Yu Chigong and Luo Shixin try it, and asked with a smile: "What do you think?" ”

"This barrier knife is portable and light, which is good for close combat, but it has a large blade, so the stabbing effect is not as good as that of a military stab." Luo Shixin said.

Wei Chigong also said: "What I want to say is that it is too light, if it is aggravated in the front of the blade, then the killing effect will be stronger." ”

"I feel the same way. The use of the barrier knife is mainly to stab and bleed, and the effect of chopping, picking, and cutting is weak, and if the enemy is wearing thick armor, it can hardly play a role... I have an idea..."Yang Tong used a sharp barrier knife to carve the shape of a Gurkha scimitar on the ground, and said: "This knife is top-heavy, wide in front and narrow in the back, thick back and thin blade, and the power is concentrated in the front of the knife when slashing, which has the lethality of an axe, which is very suitable for hand-to-hand combat and opening the way when marching from the forest." At the same time, the front of the knife has two sides of the blade and a blood groove, which has both the assassination function, of course, due to the large front part, the assassination function is also weaker. ”

Speaking of which, a long Gurkha scimitar was carved out, and it became a seven-eyed big dog-legged scimitar, "After it is lengthened, it is a sharp weapon for infantry combat; Compared with the horizontal knife with uniform strength, the force is concentrated in the first half, which is in line with the concept of 'it is better to cut off one finger than ten fingers of the enemy'. ”

After thinking about it, Yang Tong carved out the pattern of the Damascus knife again. This knife was even more powerful, when Napoleon went on an expedition to Egypt, he caused great losses to the French army, and a French general said after the battle, "The enemy cavalry wearing the Uzi steel scimitar caused a very astonishing damage to our army, and they only stretched the knife forward, and slashed the blade into the body of our cavalry by the force of the horse's momentum and the strength of the wrist, or pulled the blade horizontally, and caused terrible wounds with relative speed; Some of the soldiers were even cut into two pieces, and after the battle, many of my subordinates had different heads, and some of their bodies were broken in two, and the wounded soldiers were also very seriously injured, and the back of their hands and wrists were all cut off, and the situation was very miserable. ”

Everyone looked at Yang Tong's three design plans, and only felt the fierce breath coming to their faces, and suddenly felt that the horizontal knife and the barrier knife were tasteless.

This is not to say that the obstacle knife and the horizontal knife are useless, but the historical advantage, the horizontal knife is indeed invincible in the world in this era, but it cannot be invincible forever. The three conceptual drawings carved by Yang Tong are the products of more than 1,000 years later, and it is inevitable that they will be better than the obstacle knife and the horizontal knife, and no one can change it. This is like a cold weapon and a hot weapon, although they are both killing weapons, but the killing effect of the two is not comparable at all.

"Shengshang, this year, our army fought continuously, annihilated the anti-thieves Li Mi, Meng Haigong, and Lin Shihong, and also beat the pseudo-Tang and Feng Angou for a long time. Not long ago, the Holy Shang wiped out the Tubo and Tuyuhun coalition forces, and the right servant also fought in Jingzhou. All these battles, although they all ended in a great victory for our army, but the war consumes a lot of weapons, and after each war, more than half of the weapons cannot be used and need to be replaced, and the other half fights another battlefield, which is basically scrapped, not counting arrows and the like. So the pressure on the Ministry of Industry is too great. Jiang Xingben, the secretary of the Ministry of Works, said the hardships of the Ministry of Industry at the right time, "Although we have adopted assembly work and have been handed over to the slaves to do rough and heavy work, the craftsmen who are responsible for important links and weapon assembly are still so busy that they don't even have time to eat. ”

"Not bad!"

"Not bad!"

Ou Yeqian and other craftsmen who were fighting on the front line nodded again and again, they had the best understanding.

"I also know that everyone is working hard." Yang Tong smiled bitterly, "But we can't let the soldiers go into battle with broken weapons to kill the enemy, right?" ”

As Jiang Xingben said, the loss of weapons and equipment, arrows, and armor is very alarming, and a spear and a war knife can basically no longer be used after several battles, which is also one of the important reasons why war consumes national strength.

Ou Yeqian said: "Now the cavalry with the war lance and the infantry spear pole, are soaked in oil with a thin pole to dry and then glued with fish foam glue, although unlike the horse lance takes several years, but the process is also cumbersome, need to consume a lot of labor and materials, the existing craftsmen make up to 10,000 weapons and poles every month. Now we are completely unable to make ends meet, and we can only consume the previous inventory, but once the inventory is used up, our long weapons will be disconnected. Therefore, the lowly government has always considered replacing the existing weapon poles with wood. ”

"Did you find a replacement?" Yang Tong asked.

"Yes!" Ou Yeqian said: "The best natural weapon rod is the thick wood pole, the red thick wood is hard and heavy, and the color of the wood is bright and beautiful. It is not an exaggeration to say that it is immortal for a hundred years, and it is the best material for shipbuilding, axles, and weapon rods; The second is the ash tree, which is made of poles that are hard but not hard, soft but not broken. The poles made of these two types of wood were no worse than the oil-soaked poles we have today. ”

"Where are these two types of wood?" Yang Tong didn't know what the effect of red thick wood was, but the ash pole knew, as if it was used in large quantities in the Song Dynasty.

"Red thick wood is found in the Yanshan Mountains and Changbai Mountain Ranges, and our warships use red thick wood produced in Yanshan and Changbai Mountains; As for ash, it's even more. ”

"Then pick it up to make a weapon rod, try the effect first, if it's not much different from the current weapon rod, change it."

"Whoa."

"Holy Lord, you designed this knife, can it replace the horizontal knife and the barrier knife, and produce it in large quantities now?" Ou Yeqian came out of a family of self-made swords, and he has been studying weapons all his life, and he has learned about swords to the point of pure love, so he only needs to look at the paintings and Yang Tong's general introduction to understand the performance of the three knives, and he can't wait to create them immediately.

"This is a new weapon, don't build it in large quantities first, so as not to waste your efforts, I mean to put some samples out to test first." Yang Tong shook his head and said.

"Humble duty understood." Ou Yeqian thought for a while, and then said: "According to the method of wine blending just now, let each skilled craftsman fight each handful, and then remove the shortcomings and concentrate the advantages. ”

Yang Tong nodded and said, "This method is good." On the day the knife is completed, I will be notified to try the knife again,"

Ou Yeqian promised: "At most, in three days, the Holy Lord will be able to see the mature samples of these three long and short weapons." ”

"Good! Suspend the horizontal knives that you are about to build in large quantities! Wait for these three new knives to be tested, and then mass production. Yang Tong knows that these three knives are better than the current knives, so he will naturally not abandon them, and when they are created, they will gradually be promoted to the whole army.

"Whoa." Ou Yeqian bowed.
