It's called gasoline. ”

Wang Xiao took two steps back, avoiding the raging flames, and explained to Li Er, "The role is now, and it can be used when you fight. Or to warm up in the winter. ”

Looking at the eldest grandson Wuji, Wang Xiao laughed, "It can also be used as a fuel additive for iron smelting, and it will have a special effect with the bellows." Add fuel to the fire. ”

Li Shimin is also very interested in this, as long as it can be useful in the war, he is interested.

"Master Wang." The eldest grandson Wuji's eyes lit up and looked at the other cylinder, "What's over there?" ”

"That's good stuff." Wang Xiao introduced with great interest, "This is called kerosene, and the biggest role is that it can be lit." I'm all set. ”

Wang Xiao took out a lamp, which was the famous kerosene lamp.

The kerosene lamp is actually very simple, it is a gourd-shaped glass cover with a base and lamp head. Add another wire to adjust the wick and control the brightness.

Everything else is easy to say, but he hasn't gotten out the glass yet.

Wang Xiao's kiln factory has not yet finished the glass, so he spent a high price to purchase a batch of glass with less variegated color to polish and polish, and made a kerosene lamp.

"Go inside." When I came to the dimly lit room, I added smelly kerosene and ignited the wick with a fire medium, and the kerosene lamp was lit up immediately.

Because the glass is not pure, there are still some impurities in it, so the light reflected is colored.

But it's also very beautiful.

"Let's light the lamp now, either with vegetable oil or candles. Needless to say, wax is scarce and expensive. Wouldn't it be better to feed livestock with vegetable oil, which is cheaper? ”

Wang Xiao vigorously praised the benefits of kerosene lamps and tried his best to publicize them.

He was ready to start producing glass on a large scale, this thing was not a militaristic weapon, and he could make a good profit.

Of course, this kind of profiteering industry has to have a powerful person like Li Er to join it, so that it can make money and do business properly.

"Master Wang." Just when Wang Xiao was vigorously promoting kerosene lamps, the eldest grandson Wuji smiled and said, "This thing is indeed good." Not only is it bright, but it doesn't have the same heavy flavor as vegetable oil. But you use glass, the cost is too high, not many people can afford to use it. ”

"The eldest grandson can't afford it?"

The eldest grandson Wuji's face was straight, "The old man is only enough to support his family, where can he have the money to buy any glass." ”

The eldest grandson's iron smelting business is very large, and it can be called the largest private iron merchant in the entire Tang Dynasty.

Not to mention a glass lamp, a house made of glass is not a problem.

But the problem now is that Li Er is standing aside.

Although it is said that the eldest grandson Wuji is Li Er's brother-in-law. But Li Er is the emperor, and he is a minister who works for the emperor. Even if you become the prime minister, you still work part-time.

On weekdays, the official uniform of the previous dynasty has to be patched to show that he is poor and dedicated.

Now in front of Li Er, he said that he could use glass at home, Wang Xiao wanted to trap me?

The eldest grandson Wuji's eyes were hot, and he almost said that I invited you to Pingkangfang.

Li Shimin's face was neither sad nor joyful, as if he had not heard anything.

But in fact, he is not blind and deaf, and what the people under his command are like in private, his secret spy system has long told him.

When I thought that in order to save food and increase products, Empress Changsun took the palace maids to weave cloth, and I was angry.

"Hmph, this kind of luxury can only be used by the rich family, no matter how good the effect is, what is the use. Such objects are of little use. ”

Obviously, I am the richest one, but I still have to put on a posture that I care about the poor people in the world and despise you rich people.

You're really a tsundere.

"If you replace the glass with something that anyone can afford, is that useful?"

Wang Xiao's words made Li Shimin think, "What can I change?" Mica? Polished large mussel shells? Or crystals? None of these are cheap, and they are available in very small quantities. ”

Before the advent of transparent glass, window paper was used for the windows of houses.

It's the kind of thick white paper, the kind that can be pierced by taking a stick of incense to the window at night in film and television dramas and dipping your fingers in saliva.

In fact, real window paper is very thick, similar to the kind of tarpaulin.

Don't say it's saliva, it's okay when it rains.

The paper was so thick that it was dark even in broad daylight.

This kind of thing, the poor family will not talk about it, just open the door.

And the rich people either use glass, crystal, or mussel shells that are polished to a very thin, almost transparent inlay on the roof.

In an era of scarcity, the truly wealthy families did not lack items that could make a difference.

"Next month."

Wang Xiao put up a finger, "It can be made next month, and when the time comes, we will see if it can be used by the people all over the world." ”

Li Er's expression was upright: "If you can make the people of the whole world use oil lamps, I will never be stingy with the title of lord." ”

Wang Xiao complained in his heart, Lao Tzu gave you oil extraction technology, Quyuan plow, waterwheel, fertilizer, cement and so many other technologies. The support for Datang is so great, and now oil and glass are taken out. Is it so hard to get you a knighthood?

However, he bowed with a bow on his face: "Thank you, Your Majesty." ”

A month later, Li Shimin came as promised.

He didn't go directly to the kiln factory, but went to the granary on Wang Xiao's Zhuangzi.

Looking at the rice and wheat piled up in the granary, Li Er asked very seriously, "After you use those fertilizers, what is the yield?" ”

"The yield per mu has increased by more than half compared with previous years."

Wang Xiao believes that this increase in production can only be regarded as average, mainly because the land around Chang'an City has been reclaimed for thousands of years, and the fertility has been reduced a lot.

The Tang Dynasty was the last dynasty to rely on the Guanzhong Plain to run rampant across the world. After that, it is to rely on the land south of the Yangtze River and the north.

It is a very laborious thing to increase fertility, especially in such a vast land as the 800-mile Qinchuan River.

Li Er's eyes were a little red when he looked at Wang Xiao, "What you said is true?" ”

It seems that Datang's food will never be enough. This year, there was also a drought, and despite the presence of water wheels, it still affected food production.

The thought that there would be a large number of hungry people wandering around the gate when there was no harvest made him feel anxious.

Now Wang Xiao uses lime powder to kill insect pests and uses multiple fertilizers to increase fertility. It has achieved the effect of increasing production by more than half, and if it can be extended to the whole country, it will be equivalent to half of Datang's more grain.

That's amazing.

"If Your Majesty doesn't believe it, you can go and see for yourself." Wang Xiao said with an indifferent face, "There are still many places in the field that have not been harvested, you can personally harvest one acre and take a look." ”

Li Shimin really did farm work.

When spring came, he opened a plot of land in the palace. In front of many royal relatives and noble ministers, he personally led the oxen, and then asked the prince to help the plow, and the queen sowed and cultivated an acre of land behind. It means the arrival of spring ploughing.

Of course, the significance of this kind of showmanship is too obvious.

However, compared to the emperor who does not divide the grains, why not eat minced meat, it is much stronger.

There was no nonsense, Li Er directly picked up the hem of his clothes and went to the field.

When you come to the field, you can see a golden scene.

Whether it is rice or wheat, it is a pleasing image and full of grains.

Li Shimin didn't understand this very well, and neither did the guards around him. As for the people on the stake, he was worried that someone would cheat and didn't want to use it.

"Go to the yamen here and call people over."

Zhuangzi belongs to the jurisdiction of Lantian County, in fact, at the beginning of the year, Yushan was abolished, and after the two counties of Ningmin, Chang'an City basically belonged to Lantian County. Only the city is divided by Suzaku Street, with Chang'an County on one side and Wannian County on the other.

When the Yamen of Lantian County learned that it was summoned by the emperor, they rushed forward one by one.

Before they could salute breathlessly, Li Shimin, who was standing on the ridge of the field, was already impatiently waving his hand: "You come out around an acre of land, collect the grain, and see how much there is." ”

The emperor himself gave the order, so what else is there to say.

The county magistrate personally took the lead and rushed directly into the field, and a group of people first surrounded an acre of land with ropes. Then one by one, they took the sickles borrowed from the Wang's Zhuangzi and cut the rice.

The dealers were pointing in the distance, and occasionally there would be strange laughter.

Wang Xiao came over with two bowls of mutton soup and handed Li Eryi a bowl, "Your Majesty, eat first." ”

Li Shimin watched Wang Xiao squatting on the ridge to eat, calmed down his anxiety, and squatted on the side and began to pull the mutton soup.

Wang Xiao's mutton soup is absolutely speechless.

The mutton is processed first, and there is absolutely no fishy sandalwood taste.

The soup is made from Zhuangzili, which has been boiling since the beginning of the year, and the bones are constantly added to it without going out.

Then sprinkle chopped green onions, pour sesame oil, and add a little MSG. The taste is absolutely appetizing.

Wang Xiao beckoned, and the servant not far away came over with a plate of steamed buns.

"Your Majesty, tear the bun and soak it in soup and eat it. The amount is large and the tube is full. ”

Li Shimin looked at the steamed bun in his hand, and then looked at the field in front of him. Puzzled, he asked, "Why don't you grow millet here?" ”

"Corn bread pulls throats." Wang Xiao checked the steamed bun in his hand, "Plant wheat and grind flour, which tastes good." ”

Li Er's face darkened.

The important thing is to solve the problem first, and the taste is not important at all.

"Eat, eat, eat." Wang Xiao sucked the delicious mutton soup with a large bowl.

After eating and drinking, the one acre of land over there was quickly harvested under the concerted action of many Lantian County yamen.

But that's not the end of it, because there is still threshing.

When he was busy threshing over there, Li Shimin, who wiped the remaining mutton soup in the big bowl with a steamed bun and threw it into his mouth, clapped his hands and stood up, "Why is your mutton soup better than others?" ”

"Because of the heart."

Wang Xiao naturally wouldn't say that I added MSG to it, but this thing is his secret weapon to maintain the competitiveness of his own wine shop.

He is serious nonsense: "As a chef, you have to treat any dish with care." Only with heart can we truly do our best. ”

Li Er"( ̄〈 ̄)"

You're a fool to me. chaptererror();
