Yu Zhiqian had a headache.

Now Yu Zhiqian feels that Yu Tang's basic education is very poor, and the multiplication formulas that children learn, the dozen or so household officials in front of him are stunned for three days, and they can't help but be a little worried about their future college.

Yes, Yu Zhiqian's academy has entered the preparatory stage, and this time it is not Yu Zhiqian who pays for it, but the emperor who pays for it.

After Yu Zhiqian brought the numbers into the Yu Tang Empire, a group of household officials, Di Renjie and others actually used them, and found that it was still very convenient, except for the poor secrecy, it could improve a lot of work efficiency!

In order to prevent Yu Zhiqian from forgetting the things in his head, Yu Zhiqian's father agreed that Yu Zhiqian should set up an academy, and what he taught was what Yu Zhiqian said, but at present, the address of this academy has not been decided, the funds have not arrived, the students have not been recruited, everything is in its infancy, it is going to be the New Year, everyone is waiting for the New Year, and after the New Year, they will make a decision.

"Your Highness, although this number is good, but the secrecy is a little poor, what if someone tampers with it?"

Yu Zhiqian asked Yu Zhiqian with a smile on the side, after using numbers, it was indeed a lot more convenient, and the speed of accounting at the end of the year was also improved a lot, Yu Zhiqian not only taught numbers, but also handed over simple bookkeeping methods, expenditures, induction, etc., to put it bluntly, it is statistics, and the so-called tabulation.

This is Yu Zhiqian's junior high school thing, he taught as much as he could remember, and all the rest was returned to his junior high school teacher, as for high school knowledge, hehehe, this group of people is not worthy of learning for the time being, and Yu Zhiqian wrote it out casually, and he can do it with a big vote.

"Two ledgers, one ledger is recorded with numbers and used for statistics, and the second is recorded in words for verification, and the two accounts must be recorded at the same time, if there is a problem, the ledger recorded in writing is the main!"

Yu Zhiqian was not an accountant in his previous life, so he was not so sensitive to numbers, but after hearing what people said, Yu Zhiqian found that this was indeed the case, although it was a lot more convenient for numbers to come out, but it also gave people an opportunity in disguise.

Hearing Yu Zhiqian's words, the household waiter's eyes lit up and he nodded slowly, now the household accounting also uses two account books, one is common, the other is a private account book, and the two account books can be calculated correctly.

"Your Highness's intelligence is unmatched!"

Yu Zhiqian didn't want to do this kind of thing after just three days, and began to prepare for the New Year's celebration.

I used to be poor, belonging to the group of extremely poor households that will be eliminated in 2020, and I put a table of big fish and meat at home during the New Year, watched a Spring Festival gala, and woke up to get a red envelope, and this year is considered to be in the past.

It's different now, His Royal Highness the Crown Prince, the heir of the most powerful empire on the Blue Star, there are too many things to do during the New Year.

First of all, Yu Zhiqian needs to prepare gifts for his parents during the New Year, this thing can't be given casually, during the New Year, almost everyone has to give gifts to the emperor, if the gifts of His Royal Highness the Prince are too bad and are compared to others, it will be too embarrassing.

Although Yu Zhiqian is not a person who cares about face, but his father specially explained, and the mother who has not been coaxed for the time being, Yu Zhiqian feels that he needs to express himself well and prepare a decent New Year's gift.

Of course, in addition to this reason, but also because if the gift is good, the emperor's reward is also more, maybe you can make a small profit, the East Palace has been poor recently, so Yu Zhiqian plans to earn a little, and at the same time, it is best not to spend money on this gift.

As for the question of why the East Palace is so poor that it can't open the pot, Yu Zhiqian doesn't think about it anymore, anyway, the East Palace has never been rich.

"The glass mirror is already there, and now most of the rich people in Chang'an City already have it!"

Yu Zhiqian squinted his eyes and thought for a moment, it didn't seem to make sense to send it once and send it a second time.

"That doesn't seem to have anything to give!"

Yu Zhiqian thought about it for a long time and didn't think of anything suitable for his father and mother, the emperor must not lack anything that can be bought on the market, and there really aren't many things that he can invent and create......

"Perfume?"

Yu Zhiqian thought about it for a while, this thing has been given away by Yu Zhiqian now, but the output is a little low, there is no good way for the time being, and it has not yet made an official profit, but it seems that it is not enough to give himself cheap mother perfume, and it should be more expensive.

No money, no creativity, Yu Zhiqian scratched his head and couldn't think of anything too good, after thinking for a while, he could only take out one of his plans and send a cake!

Chinese New Year, is to figure an auspicious gift, to give a gift is to express their heart, as a son, make a cake for their father, their father should be very happy.

No, it doesn't matter if the old man is happy or not, anyway, he will be unhappy by himself, and the most important thing is that his mother is happy!

Yu Zhiqian didn't do the cream cake before, he was mainly trapped in a cream problem, and there were still more than 20 days to go, with the author's ingenuity, he should be able to Baidu to the specific production process, or go to Tang Brick to copy it......

As the New Year approaches, Chang'an City also begins to become lively.

As long as it is time to open the shop every day, the merchants will also start to make a variety of big discounts, and at the end of the year, they will be ready to make a wave of money, and the people will begin to fill in new clothes, purchase food, and be ready to live a stable year.

Yu Zhiqian led people to wander around the East Market, experiencing the atmosphere of the New Year, and at the same time looking for stalls selling firecrackers.

The seventh, the eighth, the sable cicada and the third who didn't know why suddenly followed, followed closely behind them, looking around curiously.

These guys recently started to collectively go to Yu Zhiqian's East Palace to eat and drink, Xiao Ba didn't control his mouth after eating a meal of vegetables in the East Palace, and when he went to Lao Qifu as a guest, he accidentally said that he missed his mouth, so he ......

"Your Highness, Firecrackers!"

Shen Wansan's eyes lit up, walked to a stall, and carefully picked up a firecracker and observed it carefully.

Yu Zhiqian also used this thing when he got married, but he never observed it carefully, thinking that it was similar to the firecrackers used in later generations, but when Yu Zhiqian picked up a firecracker, he knew why the firecracker was called a firecracker, because there was really bamboo.

The inferior gunpowder is stuffed inside the bamboo, there is a small fuse, and when it is lit, there will be a sound, this is the firecracker, but this firecracker is like a falling cannon in later generations, and the sound is not loud.

Yu Zhiqian looked at the firecrackers, his eyes lit up, and he already had a way in his heart, if he couldn't show his sincerity by sending a cake, then he could send a simple fireworks show, wouldn't it?

Yu Zhiqian did not start the research of gunpowder for the time being, first of all, Yu Zhiqian did not find a suitable research site, and Yu Zhiqian also knew the ratio of gunpowder, after all, there were smooth mouths in later generations, Yu Zhiqian was ready to find the location by himself, and then slowly studied it, and now there is gunpowder, but the power is very small, what Yu Zhiqian can do is to increase the power a little, that's all.

"Buy a few firecrackers and go back, by the way, who made these firecrackers?"

Soon Shen Wansan inquired: "Your Highness, it was made by a guy named Li Jin!" ”

Yu Zhiqian's eyes lit up after hearing it, Li Jin, many people don't know, but Yu Zhiqian knows this guy, the ancestor of Chinese fireworks is this one, as for why Yu Zhiqian knows, it is thanks to a documentary, the ladder.

There is such a person who wants to set off a fireworks, fireworks are like stairs, leading to the sky, and then he successfully filmed such a documentary, after Yu Zhiqian watched it, he became a little interested in fireworks, Baidu, and later knew that Li Ji invented fireworks, and also knew the general production process of fireworks.

As for why I remember Li Jin, because Yu Zhiqian didn't know the second word of Li Jin's name, I specially copied Baidu in the past, and that word was pronounced Tian in the second tone.

"Get him!"

"Whoa!"

Unexpectedly, Yu Zhiqian was not too excited, but continued to shop.

"Palace, Yu Gongzi!"

Just when Yu Zhiqian bought a candy man for Xiaoba, he heard a cry and raised his head curiously, only to see Hua Xiong wearing a long shirt looking at him with some excitement.

Hua Xiong surrendered before, the bandit leader Liu Sandao was beheaded, and Hua Xiong was left by Yu Zhiqian and thrown into the army, although he couldn't beat Xu Zhudian Wei Xue Rengui or something, but at least he was a bit of a force person, Yu Zhiqian cherished it and let him go to the army as a small colonel, and then he didn't pay attention to it.

"Huh, Huaxiong?"

Yu Zhiqian glanced at this guy curiously, and instantly focused his attention on a person next to him who was about eight feet tall, with a long beard and a flushed face, no matter how he looked at it, he looked like Guan Erye, but he and Hua Xiong seemed to be very close.

"Who is this?"

"Your Highness, this is Huaxiong's fellow countryman, Guan Yu, who came to Chang'an City to sell winter dates before, and couldn't go back because of the heavy snowfall, so I happened to meet Hua on the street......"

In fact, the relationship between Guan Yu and Hua Xiong is not good, Hua Xiong used to believe in fortune tellers, saying that he might be finished when he met a blushing himself, so he has been avoiding Guan Yu, but after the last experience of almost being cut off his head, Hua Xiong can be regarded as reforming and no longer believes in those things.

And Hua Xiong, as a person with a criminal record, lived cautiously in Chang'an City, afraid that he would not pay attention to it and anger anyone, so the previous matter was brought up, and then he went to see Lord Yan like Liu Sandao.

Suddenly met a fellow countryman, although the relationship is not good, but how to say that they also grew up together, they were still playmates when they were children, Hua Xiong immediately left Guan Yu behind, as long as he was free, he came out to chat with Guan Yu and drink, and the sulking that had accumulated for many months in Chang'an was also a long sigh of relief.

After Yu Zhiqian heard the name, his eyes lit up, it was really Guan Erye, but Guan Erye and Hua Xiong hooked their shoulders, no matter how you look at the picture, they felt a little discordant, Yu Zhiqian was afraid that one day someone would warm up a wine for Guan Yu, and Hua Xiong would.

"You fellow countryman looks burly and has practiced martial arts?"

"Childe, Guan Yu's family is poor, just like me, but he has no brute strength and no martial arts!"

"Well, you ask your fellow villagers, if you are willing to join the army, go to Chen Qingzhi and let him enter the East Palace Guard!"

Hua Xiong's eyes lit up when he heard it: "Thank you, Childe, after finishing speaking, I patted Guan Yu hard, don't thank you Childe!" ”

Huaxiong also wanted to leave Guan Yu in Chang'an to join the army during this time, but now the sixteen guards are not recruited, so he has never had a chance, and he didn't expect to meet the prince today, and this matter was done.

After Hua Xiong and Yu Zhiqian said a few more words, they left with Guan Yu excitedly and found a restaurant: "Brother Yun, you will be developed in the future, don't forget me Hua Xiong!" ”

Guan Yu still didn't understand what was going on, and looked at Hua Xiong with a confused expression.

"What I met just now was His Royal Highness the Crown Prince of the Dynasty, he asked you to go to the East Palace to serve in the guard, and in the future, the prince will become a great treasure, and you will be the forbidden army of the Son of Heaven!"

Guan Yu's eyes lit up after hearing this, and he immediately picked up a glass of warm wine: "Brother Hua's great grace, Guan Mou ......"

Finding Li Ji and meeting Guan Yu was a surprise for Yu Zhiqian, touching his chin Yu Zhiqian and thinking about a question.

"Guan Yu sells dates, Zhang Fei sells meat, and Liu Bei becomes the Shaoqing of Dali Temple, so is there still Shu Han in the Three Kingdoms in this era?"

Yu Zhiqian decided to take a good look at the history books after he went back, and maybe he could find a satisfactory answer.

After shopping around the East Market for a long time, there were all kinds of food and gadgets hanging on his body, and he slowly returned to the East Palace, and Li Zhen had already been taken back to the East Palace.

"Grass people, grass people, Li Jin, I have seen His Highness!"

Li Jin's legs trembled a little, and he didn't know what was going on, he made firecrackers at home, and someone came to take him away, asking and not saying anything, until he arrived at the East Palace, Li Jin knew that he was invited by the prince.

Li Jin is just an ordinary person, and the biggest official he has ever come into contact with is the Chang'an patrol who is not in the product, no, he should have met the county Cheng when he was in his hometown, in his eyes, the county Cheng was already very remarkable, the prince had never had the luxury of expecting it, but when he saw Yu Zhiqian standing in front of him, he almost couldn't speak.

"No need to be polite, sit down and talk!"

Yu Zhiqian waved his hand gently, Yu Zhiqian still has a lot of respect for talents, looking at Li Jin's hands, Yu Zhiqian knew that he was a person who studied gunpowder and firecrackers.

"His Royal Highness Prince Xie, His Royal Highness Prince Xie!"

Li Ji did it carefully, Yu Zhiqian looked at Li Ji and took out the firecracker: "This is what you made?" ”

After carefully observing for a while, Li Jin nodded: "This is a firecracker made by the grass people, I don't know ......" While saying that, Li Jin was a little apprehensive in his heart, afraid that something would happen to his firecracker and anger His Royal Highness the Prince.

"Well, then do you make fireworks?"

"Fireworks?"

Li Jin's face was dazed, he didn't know what Yu Zhiqian was talking about!
