Zhou Lang Zhou Lang

"Sir, since you have something to say about life and death, you can't just stand outside the camp gate and say it." Li Mu turned sideways, stretched out his hand to invite Xu Shu into the tent again.

I have been planning to find a strong and credible counselor. I originally planned to find Fengchu Pang Tong, but unexpectedly it was another misunderstanding with a weak historical foundation-Pang Tong is from Xiangyang, Jingzhou. All Liu Biao's people living in Liu Biao's territory, even if she went to poach the wall, it would not be so easy to touch the people in Liu Biao's hinterland.

Xu Shu suddenly fell from the sky and walked into her barracks, how could she let him go for nothing?

Xu Shu only felt that she seemed to be too attentive, but in troubled times, courtesy, corporal, humility and respect seemed to be the attitude of many high-ranking people. Even Liu Biao, although he didn't have the courage to accomplish great things, was still a big deal for them, celebrities who came to vote from all over the world. Preferential treatment is added.

It's just that he came to the Jiangdong army this time, but he didn't intend to tell Li Mu his life or death.

As soon as he entered the account, Xu Shu turned around and asked without waiting for Li Mu to exchange greetings: "Today, there are several people buying things together. If each person pays seven renminbi, there will be a surplus of three renminbi; if each person pays six renminbi, there will be less than five renminbi. How dare you ask Wu Cheng?" Hou, what are the number of people and the prices?"

Li Mu was about to tell him to sit down, when he didn't want to, he raised his hand and pointed at the desk. Before he could say "please sit down", he asked him face to face.Looking at him with wide eyes at the moment, my heart was dazed, not understanding what he meant.

Seeing that she didn't answer, Xu Shu suddenly laughed: "Why, Wu Chenghou is good at arithmetic, why can't he even remember the algorithm at the beginning of Chapter Nine?"

Nine Chapters of Arithmetic, after Li Mu showed "amazing" calculation ability, was also mentioned in Jiangdong, but she has never even seen what this book looks like, let alone read it, how would she know? What is the beginning?

Raising her eyebrows, she walked up to the military case, took a teacup and poured out a small puddle of water, dipped in the water and quickly listed a quadratic equation in two variables on the case, solving the problem and giving the answer: "Quan didn't read it." After nine chapters, I don’t even dare to claim to be good at calculations, but I just know some partial calculations. Sir, the number of people for this question is eight, and the price is 53.”

Xu Shu's face changed slightly.This is indeed the question at the beginning of Chapter Nine, but he slightly changed the numbers in the question. If Li Mu only reads books but not really knows how to count, in other words, if she is known to be good at counting, she just follows the book. However, it remains to be investigated whether her achievements are due to her own strength or whether there are other people behind her.

I don't want Li Mu to have never read Nine Chapters, an equation that he can't understand at all, and it's fast and accurate.The only thing I can't figure out is that Xu Shu who "falls from the sky" came to "discuss arithmetic" with her?

As soon as Li Mu reported the answer, Xu Shu flicked his sleeves lightly, and said again: "Today, there are 35 pheasants and rabbits in the same cage. There are 94 heads on the top and [-] feet on the bottom. How many are the pheasants and rabbits?"

"Huh?" Li Mu blinked, then suddenly clapped his hands and smiled, "Mr. Yuanzhi and Yueying are old acquaintances! At that time, I sent all the solutions to her. Since you know the problem, how can you ask the answer?"

There was a pause in her voice, then she blinked again, and asked with a smile, "Could it be that she deliberately made things difficult for Mr.?"

She has corresponded with Huang Yueying for a long time, in addition to ordnance design and architectural structure, she often discusses arithmetic.One of them was that Li Mu suddenly remembered this classic chicken and rabbit in a cage for later generations, and after asking Zhou Yu that there was no such question in the world's "question bank" at this time, he wrote the stem and solution of the question and sent it to Huang Yueying for entertainment. .

The numbers in this question were all made up by her backwards based on the answers. Only she and Huang Yueying knew about them. Even Zhou Yu only heard her say that pheasants and rabbits are in the same cage, counting heads and feet without knowing the exact number. Speaking of it, if it wasn't from Huang Yueying, where else could it be?

Hearing her mention Huang Yueying, Xu Shu pursed his lips, his expression slightly unnatural: "Pheasant 23 and rabbit [-], I have my own solution, I just want to hear Wu Chenghou's opinion." Neither saying yes nor no, just Urge Li Mu.

When Huang Yueying came up with this question, she saw him posing a lot of calculations, she smiled slightly, and only said when he came up with the answer: "Yuan Zhi is good at calculations, but calculations are boring."

He didn't know what it meant, so he had to come and experience it for himself, what is an "interesting" algorithm.

Under Xu Shu's persistent gaze, Li Mu touched the bridge of his nose with a smile, and said the almost joking, purely amused algorithm of writing himself to Huang Yueying: "One day, the pheasant and rabbit in the cage joined the army together. When the drum beats, one foot is raised. In this way, after two drums, seventy feet are left and 24 are left. The pheasants are all sitting on the ground, and the rest of the rabbits are all standing on their feet. Divide 24 equally to get twelve heads. The Solution of the Rabbit."

I thought it was Xu Yuanzhi who fell from the sky, but it turned out that he was a good friend.The next time I see Huang Yueying again, I must thank her well and send such a talented adviser here.

She thought that she might have a chance to meet Huang Yueying in person after arriving in Jiang Xia, but Xu Shu was stunned on the spot, his relaxed posture and crane bones completely gone.

The Pheasant and the Rabbit join the army, but the military order is still strict?How absurd!

At this moment, someone outside the door suddenly reported: "General Zhao Yun sent an envoy to see him."

Li Mu thought he heard it wrong: "Who will send the envoy?"

"Zhao Yun, Zhao Zilong, General Zhao." The soldiers outside the tent spoke clearly.

Li Mu glanced at Xu Shu, and immediately turned around and opened the tent: "Please."

Calculating the time, Liu Bei left a few days earlier than her, and she led the army to deliberately slow down. At this time, Liu Bei should have almost arrived in Jingzhou. Zhao Yun and Liu Bei were traveling together, how could they send envoys to find her at this time?

Zhao Yun is not a person who knows how to advance and retreat, and knows that she doesn't want to see Liu Bei, unless Cao Cao's soldiers approached the city like Xuzhou last time, and the army was defeated and there was nowhere to escape. Figure, I will not come to her again because of Liu Bei's affairs.

What's more, when Liu Bei arrived in Jingzhou, he was protected by Liu Biao, a fellow clan. Even if there were any dangers, Zhao Yun would not find her again.

All in all, it's weird.

Looking at Xu Shu again, I saw that he was no longer recovered, so he was surprised and unspeakable, with an unnatural expression of dumbfounding, his clear eyebrows slowly unfolded, as if he had a plan in mind.

Before he could ask in detail, a person was brought in by the guards outside the tent, and when Li Mu saw him, his heart skipped a beat.

This time, the people who went to Jingzhou with Liu Bei were arranged by Zhou Yu with all his strength. Unlike in the past, she was patrolling the camp and chatting with soldiers about family affairs. Therefore, among this group of people, she didn't even know a few faces. is one of them.

More than a year ago, Gan Ning and Zhou Yu broke Jiangxia. When she went to the city to inspect the camp, Gan Ning pleaded for Su Fei who was in Huang Zu's army. At that time, the personal guard who came to thank Su Fei with Su Fei was this person.

Li Mu didn't bother to remember it at first, but it was Zhou Yu who mentioned it the day she sent Liu Bei off, so he remembered it again.

"Xu Li, Xu Zizhu?" Li Mu found the name from his memory, and waved to Xu Shu who was about to say goodbye to her, indicating that he didn't have to avoid it, and his eyes fell on the plain-looking soldier in front of him, "Let's go In Wu County, Gong Jin had a military order in front of him, so he returned without the military order, what is his crime?"

The slightly short and strong soldier bowed to her on one knee, and bowed again after hearing the words: "My lord, it's not that I violated the military order. In fact, General Zhao ordered me to go back to the lord's tent day and night with your sword. Come on, don't stop."

In the era of war, the superiors often handed down the sword to express the decentralization of power, and used the sword as an order to directly kill those who violated it.When Li Mu left Wujun, Sun Shao gave the ancient ingot sword in front of all the soldiers, which was exactly what he said.As for gifting the Qingzhi Sword to Zhao Yun, even though she had this intention in it, she hoped that one day, when Zhao Yun left Liu Bei to serve in Soochow, he could use this sword to pass the border and enter the country, or a letter could be sent to let him know in the fastest way. she knows.

But she also knew in her heart that in Zhao Yun's hands, the Qingzhi Sword was probably just a sword matched with a hero.If you want him to use the sword as an order, even if he really joins the Jiangdong army as a general in the future, he will definitely not do it lightly.

Unexpectedly, he just came out of the border of Jiangdong, so he immediately used it!

"When I left Wu Commandery, the governor told me that he was not in the army and could not know the situation of the battle in time. Therefore, if the military order violated the order of the young master, the order of the young master must be taken first!" Seeing Li Mu groaning silently, Xu Li hastily added another sentence.It is precisely because of this that when Zhao Yun took out the Qingzhi sword and asked him to return quickly, he would obey the order.

Zhou Yu has put all his back in her hands!

Li Mu was moved.Although she has learned a lot since meeting Zhou Yu, marching and deploying troops, combining theory with actual combat, and learning from famous generals through the ages, she can be regarded as successful in her studies.But in the final analysis, she is a half-hearted monk after all.

That's it, Zhou Yu entrusted her with his retreat and the military's response after his success or failure in this trip.

Life depends on each other.

Thinking of Zhou Yu, Li Mu pursed his lips hard, his eyes were slightly hot, and the corners of his lips couldn't help showing a hint of a smile.What he said next was also a bit gentle: "Then what did General Zhao say to you?"

"General Zhao..." Xu Li was suddenly at a loss for words, and his honest face showed a look of embarrassment. After struggling for a moment, he hesitated and said: "General Zhao has nothing to tell you, and there is no letter..."

Li Mu was taken aback for a moment, not understanding what he meant.She understood Zhao Yun's difficulty in not being able to send him a letter, but if he didn't even have a word, why bother to use the Qingzhi sword to correct him and send him back?And pick someone she knows.

Li Mu has a straightforward personality and never likes to play this kind of guessing game.Before she finished guessing Xu Shu's reason for coming, now that even Zhao Yun was giving her riddles, she couldn't help feeling a little anxious.
