Datang Daily has now become a must-read publication in Chang'an City, from princes and nobles to peddlers and pawns. Because many people are illiterate, Chang'an City gave birth to a new industry, called 'newspaper readers', mostly by the streets and alleys on behalf of the people to write letters part-time, Datang Daily published what interesting things, useful news, illiterate people will listen to their questions, get the information they want.

Today's Datang Daily, from printing to sales, has formed a very complete chain. Every day at sunset, the manuscript is gathered, and after an hour the final typesetting is finalized, and it is printed overnight, and the printing is completed at the end of the day, and the door of the square is opened, and the 'newspaper sellers' of each square in Chang'an will come to the side door of the Hou Mansion to pick up the newspaper, and the average price of the Hou Mansion for selling the newspaper is one penny per paper, and it is uncertain how much they will sell it again. Some have two texts, some have three texts, but they are generally between two or three texts.

These newspaper sellers would take newspapers with them and go around the streets to sell them. Due to the limited number of newspapers, some people who wanted to be able to read the newspaper every day paid in advance, and these newspaper sellers would first deliver the newspaper to the predetermined people's homes, and then the rest would be sold in pieces.

Yue Wangfu, adjacent to the imperial city. In the second year of Zhenguan, Li Shimin named his second son Li Tai as the king of Yue and the governor of Yangzhou. Privileged "no official" and gave this mansion on the edge of the imperial city. The size of the mansion far exceeds the princely system, and the imperial historian has repeatedly played it, but Li Shimin has turned a deaf ear, and his favor is still there.

Li Shimin loves this son, not for no reason. Although Li Tai is only ten years old, he is talented and intelligent. He has the ability to never forget, calligraphy, painting, poetry, and everything. In the words of later generations, Li Tai is a 'child of someone else', who is too good for Li Shimin not to love.

In contrast, the crown prince Li Chengqian is a 'child of his own family', who does not like to study, and is very naughty, thinking about riding horses and archery all day long, which makes Li Shimin quite a headache. Selfishly, he prefers his second son Li Tai, otherwise he wouldn't love him so much. But Li Chengqian is the eldest son, and Li Shimin's own throne is not coming from the right way, and he can't let his son repeat the mistakes of the past. Moreover, the word 'Chengqian' in Li Chengqian's name was given by Li Yuan himself, which has the meaning of 'inheriting the imperial industry and leading the Qiankun', and after Li Shimin ascended the throne, the first thing he did was to make Li Chengqian the crown prince, most likely to appease his father and stabilize the court.

Moreover, although Li Chengqian is naughty, he has the temperament of Li Shimin's youth. Li Shimin likes Li Tai because Li Tai did what he wanted to do but didn't do, but Li Chengqian was a young man, so although the prince had a little problem, Li Shimin was not really disappointed. Li Chengqian is also very smart, although he likes martial arts and does not like literature in his heart, but whenever he takes the school examination, he can always pass the test, and Li Shimin rarely reprimands him.

People's ideas change as they grow up, and Li Chengqian and Li Tai at this time are just children. Li Shimin is in his prime again, and the situation of the two kings seizing the heir in the TV series in later generations, at this time, they don't even have a thought in their hearts.

Li Chengqian is dedicated to martial arts, and Li Tai is dedicated to literature. The two brothers each specialize in one set, but there is nothing discordant.

It was the same on this day, Li Tai woke up from the hundred-square-meter dormitory, yawned, and four maids came to dress him, and all he needed to do was to stretch his arms out.

After getting dressed, one of the maids combed Li Tai's hair, and the other maids retreated, and after a while, they came to serve with toiletries. Li Tai opened his mouth, and a maid took a 'toothbrush' made of ivory bristles, dipped it in fine salt, and poked into Li Tai's mouth to brush his teeth, doubly careful, for fear of touching his throat and causing Li Tai to retch. After brushing his teeth, he was afraid that the fine salt was too salty, so he quickly brought mouthwash, and after feeding Li Tai to rinse his mouth, another maid took a hand towel soaked in warm water to help him dry his face, and the part of his double chin was wiped more carefully.

I wiped my face, and my hair was almost combed. The maids took down the toiletries and brought four sets of robes for Li Tai to choose. Li Tai pointed to one, and the maids helped him put it on. From the beginning to the end, he didn't have to exert half of his strength.

"Your Highness, today's Datang Daily newspaper is here."

"Show me."

Only at this time will Li Tai take matters into his own hands. The maids who were waiting for them all withdrew, and he wouldn't have remembered to eat until Li Tai had finished reading Datang Daily.

Li Tai likes Datang Daily very much, he is an otaku, except for reading all day, he rarely has other activities, so he is fat to this weight, ten years old, one hundred pounds, a little fat man. Datang Daily can let him know about the outside world, especially Li Mu's serialized "That Year the Moon is Full", although he doesn't like martial arts, but when he sees the scene of soldiers fighting the same enemy, he is still inevitably enthusiastic.

When reading Datang Daily every day, Li Tai always looks for it first, if not, then looks at major events in the DPRK and China, and finally looks at lace news and advertisements.

"Huh?" When today's newspaper arrived, Li Tai frowned. In the past, newspapers had only one piece of paper. And today there was one more, Li Tai couldn't help but be curious, put the first one aside, and picked up the second one to look at it first.

"Do you ask?"

Li Tai is well-read, and he has naturally read "Qiu Jian's Sutra". He also tried to answer this question, but after trying for several months, he specially invited Li Chunfeng to study it together, but he didn't come up with a solution. When he was really out of options, he even raised 300 chickens in the mansion and tried to try out a solution, but in the end he failed. Therefore, when he saw this problem, his first reaction was not that someone had solved it, but that he was thinking, why did Datang Daily publish this problem, is it to brainstorm ideas?

Li Tai continued to look down, and the whole person suddenly froze.

Three answers! Actually, there are three answers?!

Li Tai couldn't believe that someone had solved it when Baiji asked. He looked down a little further, expecting to see the solution. But he was disappointed, there was no solution, just an answer. Underneath the answer, there is another line of small print.

[Baiji asked, from "Qiu Jian's Sutra", there is no solution to the problem in ancient times. Today, Li Mu, the Hou of Zhulu, invented four algorithms and successfully solved this problem. In order to promote the progress of Datang arithmetic, the four algorithmic foundations are now disclosed, and I hope that the people of the world will learn from them. 】．

"It's another deer chase!"

Li Tai reads Datang Daily every day, and he is already familiar with Li Mu's deeds. He admired Li Mu's poems very much before, but now that he has solved the Baiji question, Li Mu's image suddenly became a little taller in his heart.

He hurriedly looked down, and this one was incredible, like a treasure. The shouter brought a pen and paper and did the math.

……

Li Mu also got up early today, but it wasn't that he remembered early. But Cheng Yanjin came to the door early in the morning, and there was no way not to get up.

Cheng Yanjin really can't wait, and last time Marseille easily earned 7,000 yuan. In Cheng Biting Jin's heart, the horse farm is like a mountain of gold. And Li Mu didn't let the next one be held, but kept arranging people to do things he couldn't understand at all, which made Cheng Yanjin very upset every day, he just couldn't figure it out, obviously the money was on the ground, and he could pick it up by bending down, why didn't he pick it up?

But he didn't dare to say these words to Li Mu, he was afraid that if Li Mu was annoyed, he would leave it alone. This big mess was all thrown away, and it finally lasted until the end of the month. According to the agreement, three days later is the next Marseille period, Cheng Yanjin finally waited for the opportunity, and early in the morning, the horse farm was ready, and he wanted Li Mu to go over to check it out, and came to the house to disturb people's dreams.

Li Mu didn't forget about it, according to his plan, he wanted to wait for Marseille to take a look the day before, and he wouldn't delay the matter. But Cheng Yanjin was already in the house, if he didn't follow, it seemed that he didn't plan to leave, so he had no choice but to follow.

As soon as he went out, Li Mu was frightened by the battle in front of him. In front of the Hou Mansion, there were two teams of forbidden troops, and those who didn't know thought that Cheng Yanjin had led the troops to raid the house.

"Uncle, this battle ...... Is it necessary? ”

"Of course it's necessary." Cheng bit Jin Zhengse and said: "It's only been a few days, and you forgot about the assassination?" What if someone stabs you again? These are the old man's personal soldiers, with one as ten warriors, with their protection, even if it is in front of the two armies, you can be guaranteed seven in and seven out. ”

Li Mu secretly said in his heart, why did I go to the front of the two armies to enter and exit seven times. You old guy are afraid that if I die, no one will help you make money, right? Shaking his head, he didn't say anything, and climbed on the horse's back.

At this time, Cheng Yanjin saw the axe behind Li Chongyi, and his eyes lit up.

"Hey? Where did the axe come from, why hasn't the old man seen it? Little baby, show it to me. As he spoke, Cheng Biting Jin was about to reach out to take it, Li Chongyi didn't care who he was, seeing that he was about to grab the axe, he swung Cheng Biting Jin's hand away with a slash of his arm, Cheng Biting Jin couldn't bear Li Chongyi's strength, his body was crooked, and he almost fell off the horse.

Seeing this, the forbidden soldiers drew their swords one after another, and eight horses surrounded Li Chongyi.

Li Chongyi glanced at it, did not speak, took the axe in his hand, and the iron chain around his waist buckled the mechanism of the axe handle, as long as Li Mu nodded, the axe wheeled out, and it was eight and a half corpses.

"Big! Don't be presumptuous! ”

Cheng Biting Jin also said: "What are you doing, who told you to draw your sword, disperse!" ”

The forbidden soldiers dispersed, and Cheng Biting Jin said: "Little baby, the old man just wants to see your blade, and he doesn't want to rob it, so borrow the old man to take a look." ”

"You just want to rob it."

Cheng Biting Jin's old face turned red, and he was extremely embarrassed. Li Chongyi was right, he really planned to grab it just now, he originally used an axe, Li Chongyi's blood prison axe is domineering, how could he not like it. If he grabbed it and begged for it, Li Mu was a junior, could he not give it? It's just that he didn't expect Li Chongyi to have so much strength, he didn't grab it, but almost made a fool of himself.
