When Zhang Daren happily led Xin Guangmao, who was full of excitement, to leave the Lin Mansion, Jia Yi and the two of them were full of blessings, hoping that Zhang Daren could spread the way of arithmetic throughout the army, and hoped that Xin Guangmao could use this as a springboard to successfully enter the official career.

The wedding day was set three days before the Spring Festival, that is, the twenty-seventh day of the New Year, and now it has entered the lunar month, and there are not a few days before the wedding day.

In order to make his wedding more distinctive, Jia Yi decided to make fireworks and firecrackers himself, and set off on the day of the wedding.

The second foot is the most simple thing, when he was a child, Jia Yi was naughty and made it himself with the medicine in the firecracker, although it was not as successful as imagined, but it could be regarded as flying into the sky, making a doctor's noise.

Just think about it, the ice cellar has not been filled with water for a long time, so that all those saltpeters have been returned into powder, Jia Yi got twenty catties, sulfur is sold on the market, these years there are fewer people and more land, there are snakes and insects everywhere, when you go out, you really don't dare to sleep without sulfur, maybe there is a snake or worm on the body, and the little life will be whining and lamenting.

Charcoal is all over the street, originally in winter charcoal should be the most popular heating item, but with the spread of the stove in the house, the entire Chang'an City and all the nearby counties, have begun to use the stove, no one is using the charcoal basin, charcoal replaced charcoal, became the fuel for the heating of the stove group.

In this way, charcoal has been sold all year round, but this year it is a big upset, except for some people who can't afford to buy stoves and charcoal will buy a little low-priced charcoal, charcoal basically can't be sold.

After buying the sulfur, he ordered a charcoal seller and asked him to bring the charcoal home with him.

Charcoal, sulfur and saltpeter are all available, and the rest is compatible, Jia Yi clearly remembers the mantra of one sulfur, two hustle and three charcoal, considering that what he wants to do is to set off fireworks, not black powder, after thinking for a while, the amount of charcoal has changed from three to ten, even if it will deflagrate, at most it will make the fireworks more beautiful, and there is no need to worry about causing a violent explosion.

I found a long piece of hemp rope, soaked it in castor oil, exposed it to the sun, and after all the oil stains got into the hemp rope, cut it into a small section of long strips for later use, summoned some finger-thick bamboo poles, cut them into many knots, buckled the transverse partition at one end, and then put some mud alive, and the preparation was completed, and the rest was to make gunpowder.

The pottery bowl and pottery hammer are ready, all the things that are weighed are poured into the pottery pot, and then all of them are ground into powder with a pottery hammer, first pour a little gunpowder into the bamboo joint, put in a hemp rope, pour in the yellow mud, and wait until it is dried, after pouring gunpowder, put in the hemp rope, and paste it with paper, a simple firecracker is completed.

Looking at the freshly baked two feet, Jia Yi thought about whether to find a place to put it, I don't know if it will work, don't make it when the time comes, it will be a shame for adults.

In this era, anyone who can make a sound in the sky, the people will generally think that it is a sound made by God, either thunder or a cough of God, in short, no one will believe that humans can make a loud noise in mid-air.

In order to avoid unnecessary trouble, Jia Yi decisively chose to set off by the river, but when he packed up the materials and took the two feet he had just made and was ready to go to the river to set off, Jia Er walked in with a frown, and he also had his hands behind his back, and he had learned to carry his hands behind his back at the age of fourteen or fifteen, and before he could speak, Jia Yi gave him a slap first.

"What do you pretend to be old at a young age, let me see you with your hands behind your back in the future, and I will give you a discount on your hands."

After the lesson, seeing that Jia Er didn't react, he asked casually: "If something happened, tell me about it." ”

"Big brother, although the ten shopkeepers we sent out, although they all successfully opened restaurants, I don't know what's going on, there is still a large amount of edible oil in those counties, and looking at this meaning, they can continue to see each other for a long time."

"The annual output of rapeseed is not much, and there is only a small amount of edible oil that can be used to make edible oil, so where does their edible oil come from?" Jia Yi also expressed great puzzlement about this, to say that they spent a lot of money to buy from outside, and they didn't believe it when they killed Jia Yi, who could have such a large business scope, one or two can be said to be a coincidence, and there was no way to bump into it, but all ten counties had this kind of businessman, and he didn't believe it.

There must be someone in this who is engaged in malicious competition, but Jia Yi doesn't know, but he thinks of the guy who directly abandoned the four restaurants and left them for him, but there is also his shadow in this.

If all this was really the one who gave it directly to Jia Yi or four restaurants, this kind of thing could really happen.

However, Jia Yi did not spend too much energy on this matter, but directly chose the curve to save the country, that is, to change the dish, in winter, the most popular is not stir-frying, but hot pot, on the one hand, hot pot warms up, and in addition, this novel way of eating will also bring good enjoyment to diners, and it should be able to make a small fire.

Looking at the firecrackers in his hand, Jia Yi felt that it was more important to get down to business than to play, and it happened that it was almost dinner time in the evening, so he simply didn't cook anything tonight, and directly set up a hot pot to calculate.

A small charcoal basin, plus a small shelf, on top of which a basin is placed, in which all kinds of spices are placed, just waiting for the fire to boil. Let the cook cut the mutton into thin slices, in the cold winter, the mutton has long been frozen very hard, no matter how you cut it, you can cut the mutton into thin slices, prepare some green vegetables, and then some pork and chicken, a hot pot is formed.

It just so happens that the peanuts have been harvested, make a little ground into a pulp, put in the garlic cauliflower, add some salt, stir and stir is the small ingredient.

After beckoning the family to sit down at the table, Jia Yi briefly told everyone about the ways and means of eating hot pot and precautions.

The people who had long been a little impatient, without waiting for Jia Yi to finish speaking, picked up the mutton and put it into the boiling pot, the original bright red mutton, just after entering the water, it turned earthy yellow, and after a little boiling, it was fished out, dipped in the small material, and then put it directly into the mouth.

Different ways of eating bring different taste enjoyment, and after eating this delicacy, chopsticks soon began to frequently come and go between the dish and the pot.

A lot of vegetables and meat that had been prepared disappeared quickly and quickly with the naked eye, and after half an hour, all the plates on the table were empty, and the people at the table were gently caressing their stomachs and leaning back on the chairs to burp.

Jia Er, who was full of food and drink, knew Jia Yi's thoughts, and after a short rest, he ran out directly, believing that soon the hot pot will be popular in Chang'an and the surrounding counties.

Hot pot is just like Jia Yi thought, and soon set off a hot pot craze, friends in twos and threes walked into the Sifang restaurant together, ordered a hot pot, chatted while eating, and drank whatever they wanted, freely.

The Sifang Restaurant or Qingyun Restaurant, which was originally resolutely resisted to enter the city, was just a small proposal, which completely broke the situation that it was difficult to enter the city, and even some people specially went to the Sifang Restaurant from various locations in the county.

The problem was easily and happily ended by Jia Yi, Jia Yi then remembered the second kick he made, and now that he is finally idle, it is better to hurry up and test it, there are not a few days left before the wedding.

Jia Yi, Jia Er and Shen Qingyun came to the riverside of the greenhouse area together, Jia Er and Shen Qingyun were more curious about what Jia Yi was going to do by the frozen river, so they saw Jia Yi take out a small bamboo knot from his arms, and then put it on the ground, blowing the fire fold, under the curious gaze of the two people, quickly lit the hemp rope, and then covered his ears and ran towards the place where Jia Er and Shen Qingyun were, not caring about what to say to the two, just opening his mouth slightly and covering his ears with his hands.

"Tom"

A light sound startled Jia Er and Shen Qingyun, you must know that when the two feet are flying, there will be a burst of fire, just lighting a small hemp rope, it can produce such a huge sound and such a dazzling light, it has shocked the two of them beyond measure, just when they were about to come up to Jia Yi to ask how this happened, Jia Yi kept staring at the small bamboo that began to fall with his head up.

Maybe the hemp rope is too long, or maybe the fuse made of oil is too slow, in short, in the process of the small bamboo knot slowly falling, he has been looking up, for fear that this thing will fall into the crowd, and it will cause a lot of losses at that time.

Seeing the landing location, Jia Yi yelled at Shen Qingyun and Jia Er, and quickly pulled the two of them away from the small bamboo joint.

Jia Yi's words fell, and a loud bang came from the direction of the small bamboo.

"Boom"

Shen Qingyun and Jia Er were startled, and then looked at the black smoke that kept rising from the place where the small bamboo node exploded, and the two of them swallowed their saliva in unison.
