Han Xin gave Liu Chang the feeling that he was similar to Empress Lu, but it was slightly different.

Indifference, loneliness, melancholy, or rather, the whole era gives Liu Chang the same feeling, except for the big grinning father, and the group of silly brothers, the faces of others are always sad and can't be dispersed, in the palace where there is no green at all, on the gray buildings, people can't find the slightest bit of happiness.

The suffering caused by the war was enormous, and this suffering did not get better because the war ended, and the whole of China silently licked its wounds after the war, weeping for those who died in the suffering and are suffering.

Before Liu Bang, China had already experienced more than 200 years of war, and in the past 200 years, the number of soldiers killed in battle alone has reached nearly 3 million. Behind every soldier who died in battle was a broken family, weeping parents, wives who missed their beloved, and children who lost their fathers.

And the disasters caused by the aftermath of the war have taken many lives.

What seemed to be a cold number in later generations was also a living life at that time.

The war is over, but the rich arable land everywhere is overgrown with weeds. The parents who were sitting at the door waiting for their children were gone, but the strong pillars of the family still did not return.

Whether it is Han Xin or Empress Lu, presumably their sorrow has nothing to do with these, but it must not be said that such an era has not affected the sentient beings living in this era.

"Master, how are you going to teach me? Are you going to take me to the barracks? ”

Liu Chang sat excitedly in front of Han Xin, without the slightest uneasiness or restraint.

This surprised Han Xin a little.

After Han Xin showed his talents, almost no one dared to be so casual with him, and Liu Bang was the only one who dared to ridicule him and joke with him. A fierce man like Fan Hao only dared to bow to him, and didn't dare to look up at him, Xiao He was the first to talk to him carefully, and he didn't dare to slack off, as for Zhou Bo, Chen Ping, Jiang Guan, Sui Lu, Cao Shen, Xiahou Ying and others, he didn't pay attention to them at all.

Han Xin glanced at him before he said, "I can't go to the barracks." ”

"How do you teach that?"

"If you want to learn the art of war, it is useless to read books, you have to start learning from the most basic things."

"Okay, then you can teach!"

Liu Chang picked up the pen and the incomparably precious paper, this was the first time he had ever listened to the lecture so carefully, after all, this was the course he was interested in, no matter which man he was, he had a military dream in his heart, not to mention that in ancient times, the temptation to lead thousands of troops and horses to conquer the city was irresistible.

"Five armor soldiers eat 150 stone of millet a year, if you want to take 20,000 armor soldiers to the battle, the estimated battle time is two years, how much food do you have to prepare?"

"Uh-huh???"

Liu Chang's eyes widened, is this the art of war or mathematics?

And it's too simple, isn't it?

"1,200,000 stones."

Liu Chang said the answer without thinking, Han Xin obviously had a trace of surprise on his face, although there are already multiplication tables in this era, and people who know mathematics can calculate it in minutes, but at Liu Chang's age, it is still good to be able to calculate it so quickly, which is obviously a little different from Han Xin's son who does not learn and has no skills.

"It's not bad..."

"This is the art of war??"

"This is part of the art of war, however, your answer is wrong, you have to prepare 2 million stones."

"No way, 1.2 million is right."

"There will be a waste of food on the march, accidents may occur, and the war may be delayed, so at any time, the food prepared must be far greater than the food necessary for the battle."

Liu Chang suddenly realized that what he said was very reasonable, although it was still simpler.

Next, the knowledge taught by Han Xin is the foundation of the basics, and there is no such advanced tactics that can defeat Xiang Yu as Liu Chang thought, although it is only some basic knowledge, but the lecturer is Han Xin after all, Han Xin often gives examples in the process of telling, and the examples he gives are his own personal experience.

Liu Chang listened to the story as if he was particularly fascinated.

"Master, how did you defeat Xiang Yu in the first place? Tell me, Xiang Yu is such a fierce person, how did you defeat him? ”

During the break, Liu Chang pestered Han Xin, not letting him tell him a story, although Han Xin occasionally gave examples when lecturing, but he asked him to say it in detail, but he was unwilling, he seemed to be very reluctant to recall the original incident, his face was full of displeasure, and he didn't say anything about letting Liu Chang splash and roll.

Han Xin's personality is really diametrically opposed to Liu Chang, water and fire are incompatible, Han Xin is a serious and rigid person, because of his long-term experience in leading soldiers, he governs people strictly, and he doesn't like to make noise, and Liu Chang is a living treasure, and he can't be quiet for a moment, and he is very noisy.

Han Xin didn't like this little apprentice very, very, very much, and when Liu Chang was shouting around with his sword, he finally couldn't help it, and with a black face, he asked the house slave to pull out the goods and ask him to come back tomorrow.

Liu Chang liked Han Xin very much, he felt that this melancholy uncle had an inexplicable charm, and his lectures were also very interesting, so he returned to the palace with great expectations.

As soon as he returned to the palace, before he could brag to his mother about his performance today, Liu Chang was brought to Liu Bang.

Liu Bang was concentrating on reviewing something, Liu Chang stood on tiptoe and peeked a few times.

Only then did Liu Bang put away the bamboo slips, tilted his head sideways, and looked at Liu Chang.

"Got back from Han Shin?"

"Hmm."

"How's it going?"

"Very good, the teacher is very happy and very satisfied with me."

"Studied the Art of War? Or did he teach you personally? ”

"The teacher taught me personally."

"Did he ask about you?"

"Huh?"

"It's just to ask how you're doing in the palace, or how you're doing in the palace."

"Nope."

"Did he mention your mother, or your brothers?"

"Nope."

"Well, I don't tell anyone what I'm asking you for, otherwise... I smashed your spinning wheel. ”

“.... Got it. ”

Although Liu Chang is skinny, he still has a certain fear of Liu Bang, he knows that Liu Bang has always done what he says, so after seeing his mother, he did not tell her what Liu Bang asked. However, what is confusing is that Empress Lu also seems to have suddenly become interested in his study with Han Xin.

Even, Empress Lu asked exactly the same question.

"Did he inquire about the situation in the palace?"

"Did he ask me or your big brother?"

The eldest brother mentioned by Empress Lu is Liu Ying. Empress Lu only seems to admit that she has two sons, and when she talks to Liu Chang about other princes on weekdays, she calls them by their names, and only when she says Liu Ying, she will say your eldest brother, and the same is true for Liu Ying, only when she talks about Liu Chang, she will say your younger brother.

Of course, at the end of the conversation, Lu Hou also threatened and intimidated Liu Chang like Liu Bang.

"If you say it, I won't give you beef in the future."

It can only be said that his parents have seized Liu Chang's death hole, so that he can't talk nonsense outside. Liu Chang himself was afraid that he didn't realize that he had fallen into a very terrifying political whirlpool, no one dared to relax, and everyone was facing the same threat.

Liu Chang was still busy with his own affairs, and when he heard that Liu Chang was making a spinning wheel, Liu Ying came again and encouraged Liu Chang with a smile, saying that his behavior was worth learning from other princes. In the early Han Dynasty, when Confucianism did not rise, or degenerate, no one hated inventions and machines.

The Qin and Han dynasties encouraged invention and creativity, and in the "Violent Qin", if you can invent a new machine that benefits the country, then you can be promoted. Of course, my Han will not copy "Tyranny Qin", in my Han, if you can invent something useful, you can get a reward, and the reward is usually to upgrade your title. It can be seen that my Han has absolutely no plagiarism of "Violent Qin".

Therefore, in this era, engaging in invention and creation is not unlearned, and Liu Ying also supports Liu Chang's idea.

Liu Chang was initially reluctant to tell Liu Ying about this, mainly because he didn't want to listen to Liu Ying's reasoning.

Liu Ying still talked about a big truth, from the importance of invention and creation to filial piety, and then to the folk clothing problem, from Taoism to Confucianism, and from Confucianism to Legalism, even Mohists also mentioned.

It's just that Liu Chang didn't understand his tirade, so he just nodded stupidly.

Facts have proved that the eldest brother is still reliable, although he gave Liu Chang a certain amount of mental torture, but before leaving, he asked people to bring back all the tools and raw materials that Liu Chang needed. Liu Heng and Liu Ruyi can't handle what they can't do, Liu Ying can completely handle it.

Liu Chang was overjoyed, a big brother, and Liu Yingmei raised her head with a smile.

ps: Let's make a few points, first of all, in order to allow Liu Bang and others to appear, the old wolf deliberately increased the age of some princes, after all, these settings are for the sake of the plot, I hope you can understand.

In addition, about the protagonist's historical illiteracy, I myself am a student of history, in order to be able to write a good science and engineering protagonist, I asked a lot of friends who have worked and are in line with the protagonist's previous design. Most of them all know Liu Bang, Lu Hou, Han Xin and others, know Liu Che, but don't know Liu Heng, I asked about a dozen friends, only two know that Liu Heng is Emperor Wen of Han.

In fact, the old wolf doesn't like everyone arguing about these things, I hope everyone can pay attention to the plot and talk more about the plot, rather than these settings and attributes, I hope everyone can give more of their own ideas, understanding and opinions on the plot, which will be very helpful to the old wolf's next creation.

Thank you.
