The sound of horse hooves rang in front of the Jinning City Yamen. Carrying the military orders with ink marks, a general of the Hedong Army stepped on their mounts and rushed to their battlefield one after another.

The whip waving in the rider's palm was no longer obvious, leaving only a faint figure. Huang Shang watched the last general leave the city. The tension before the war was like a heavy bluestone, inexplicably pressing on his heart.

When he was at Yanmen Pass, Huang Shang still felt like a bystander. But this time he encircled and blocked the robber Bu, he participated in the whole process. Although the enemy was only a few thousand, after getting into every link of the war, Huang Shang realized how cumbersome it was to organize a battle.

All aspects of weather, geography, personnel, food, military equipment, and enemy situation must be considered. Moreover, in the planning and operation of these pre-war periods, the relationship between the generals and schools and the balance of power must be considered, and their greatest will to combat will be stimulated, and at the same time, they cannot be allowed to underestimate the enemy and advance in order to strive for merit. The grasp of people's hearts is ten times more difficult than the mobilization of materials.

A war is by no means the cold words such as great victory, great defeat, victory, and defeat that exist in history books. All those involved are living people.

I watched a famous general and school leave with the belief of winning, and no one could have predicted how many of them could return safely. As a staff member involved in the planning, their lives may end with one wrong sentence.

Huang Shang was so heartbroken that when he returned to the inner hall, he saw Zhe Keshi copying military orders.

All of them are Hangang's classmates. They all boast about their own poetry and books. When drafting military orders for Hangang, they inevitably brought a sense of sourness. At the beginning, they even had articles about Sili and Liliu several times. After being taught by Hangang a few times, the style of Siliu disappeared, but even Huang Shang wrote the same thing, it still seemed too literary. Some words easily confused the generals who were already illiterate and their low-level staff.

When drafting official documents, Han Gang asked so. When he published several regulations and books on medical skills in the past, he would rather lose the cumbersomeness than pursue the literary style of rhetoric and never harm the will of words. Therefore, it is not surprising when he put his own requirements on military regulations.

Han Gang once said that the words of official documents and decrees in the army must be precise and unambiguous, and must be easy to understand, so as to avoid misunderstandings by those who accept the orders. This is a general rule in the army, not the rules set by Han Gang. However, few civil officials in charge of the military are willing to damage their faces and be ridiculed for their literary talent, just to prevent the generals and officers below from misreading their fate.

What Zhe Keshi is doing now is to write some military orders that are too obscure, which have created many ambiguities, and re-translate the words that the proofreaders can understand, and then submit them to Hangang for review and confirmation, and send them out.

When Huang Shang came back, he saw that Zhe Keshi was so busy that he didn't even have time to say anything, so he didn't bother him. But when Zhe Keshi heard Huang Shang's movement, he put down his pen and said, "Mian Zhong, everyone has sent it away?"

Huang Shang nodded: "Everyone is out of the city,"

Zhe Keshi looked up at Huang Shang again, "Brother Mian Zhong, what did the imperial court say to you before you went to war? Why did you seem to be in a bad mood when you see you now?"

Huang Shang stopped for a moment, thought about it, and then briefly explained his feelings to his new friend.

"...It's good if you get used to it." After hearing this, Zhe Keshi said indifferently, and treated it as an admonition.

However, when Huang Shang saw his attitude, he became very shocked. Unexpectedly, Zhe Keshi, a kind person who has usually reduced the attitude towards war, looked like this.

Zhe Keshi had no time, but he was busy and said without raising his head, "Since he had eaten this bite of food, he died on the battlefield and saw too much. Now only one of his grandfathers and six of them survived. The remaining fifteen uncles and uncles, six of them died on various battlefields, three of them died of old injuries, and the rest were all kinds of diseases, sooner or later, only my grandfather died. For this reason, you can ask Longtu. He started from the northwest border with Wang Xianggong. At the beginning, he had fewer people in his hands than you and me, and was closer to the generals who were in battle."

"Not everyone can compare to Longtu." Huang Shang sighed, but walked towards Hangang's living room. He did not want to ask Hangang's mental journey - he did not plan to ask - but went back to pay the order.

Huang Shang was the queen who was famous for entering the hall. Han Gang was looking at a letter, and there was a brass cylinder on his table, something Huang Shang had never seen before.

"All people are gone?" Han Gang put down the letter in his hand. His question was almost the same as that of Zhe Keshi just now.

"Everything is gone." Huang Shang nodded, "It's very refreshing to leave, no one hesitates to delay."

“…I want to make contributions and receive rewards as soon as possible.”

People die for money and birds die for food, which is inevitable. Huang Shang suddenly felt a little heavy. Then he laughed and said to Han Gang: "With these arrangements made by the dragon map, the bandits of Bu will inevitably be unable to escape. In this way, in the first half of the year, the news of Beizhubu annexing the grassland tribes will reach Taiyuan Prefecture."

"Things are not as simple as it is." Han Gang shook his head, "What do you think we can think of Yelu Yixin? As a traitor in charge of the Liao Kingdom, he is far more than a hundred times, thousand times, or even ten thousand times stronger than us. Since Xizhubu went south to help Xixia, then wouldn't he prevent Beizhubu from taking advantage of the situation, with Yelu Yixin's talent, make preparations for this?" He laughed, "I wouldn't be too surprised that the father of the Great Liao Dynasty took the plan to attack the Beizhubu who went south to annex the Xizhubu tribes, and even wiped out all of them."

"...Why did the dragon map do it?"

"Do nothing, there will never be any results. Only by doing it can you have the opportunity to achieve success."

"Success?...Does the success of Dragon Tu have to make the blood debts of the thieves pay for their blood?"

"Yes, blood debts are paid for blood." Han Gang pursed his lips, and his pupils became deeper. "Since he had seen the tragedy in Yongzhou, he had to use blood to repay the blood debts left by the barbarians from all directions in our Han territory."

Huang Shang can understand Han Gang's mood changes very well.

Due to Han Gang's leadership, all the male men in Jiaozhi have been punished and have become slaves of Dongman in Guangxi. They have planted sugarcane and rice for Dongman, who divided the land of Jiaozhou. He still remembered that a friend once pointed to the snow-white Jiaozhou sugar and said, "Although these Jiaozhou sugars are as white as snow, they are actually full of blood."

But if it were now, after Huang Shang checked a village that was breached by the people of the vassals, when he heard someone slaughtering the Jiaozhi people in Yongzhou, he would definitely curse in person.

Han Gang raised his eyes and asked Huang Shang, "Mian Zhongke still remembers the 40th chapter of the Chinese Book?"

Huang Shang raised his eyebrows: "Those who violate the powerful Han Dynasty in a clear way will be punished even if they are far away?"

"Ah. That's right." Han Gang smiled, "Although I'm talking too much to people now, I'm often scolding people. But the one I like most in the hundreds of books of Han is 'It's better to hang my head and stand up in the barbarians' residences to show that those who violate the strong Han will be punished even if they are far away!" Although Ban Mengjian [Ban Gu] did not say good things about Chen Tang in the praise after the volume, the number of biographies in this volume is the longest, and it is even longer than the other ones. The elder brother of Ban Zhongsheng [Ban Chao] must have been unable to curb his pen when writing Chen Tang's biography."

Huang Shang nodded. Chen Tang's words are usually just a thrilling moment, but the war is in full swing and the situation is in time, but it can't help but touch people's hearts.

"Zou Yan used to have a saying about the big Jiuzhou and the small Jiuzhou. Looking at the land of China, it was only a Chi County Shenzhou. Outside the land of China, I don't know how much land and population there are. All the world is the king's land, the shores of the earth, and the king's ministers. The Han and Tang dynasties worked hard for this, but the next thing was really not a good tool. The Three Kingdoms and Five Seasons of Central Plains, and the screw shells were too small. The world is not limited to the land of Jiuzhou. Therefore, reading the biographies of Chen Tang and others is much more enjoyable than the history of the Five Dynasties. The Han Piao Astronomy History Book was not qualified, so he changed the topic: "I remember that the scholars said in the past. In "Guichuan Congtan", it mentioned that the earth was spherical, and because of its inner diameter, the outer circumference was nearly 100,000 miles. Because of this, people could not find that it was spherical."

"How to determine that the earth is a spherical shape has been explained thoroughly, but the lack of accurate numbers is like a speculation. When it comes to this, when trying to accurately calculate the length of the meridian, the monks in the Tang Dynasty once calculated it, but the error is too much. Qi should be based on seeking reality and seeking truth. To study things and seeking knowledge, it is a true and unerrible word "reason"."

It was not a whim when organizing manpower to measure the meridian. In Kansai, Cheng Yi had just finished his lecture for more than a year and returned to Luoyang. In more than a year in Guanzhong, he had instilled Cheng Menluo's studies into many Guanzhong scholars. Su Bing is still supporting the overall situation at Hengqu Academy, but is unable to fight against Cheng Yi. Han Gang cannot just stuff his fellow disciples into his shogunate, but must make new achievements in academics or prove his unique views. Although it is not imminent, he does not have much time left.

Han Gang thought, and picked up the brass cylinder on the table and handed it to Huang Shang: "This is a new thing sent by the emperor to assist the military. Recently, a glasses maker in the yard presented it to the emperor."

Huang Shang took it and fiddled with it casually. He found that the brass cylinder was a simple two-section sleeve, with a crystal lens in front and back.

"Is it a microscope?" he asked, while pulling the cylinder open with a familiarity, looking at himself and towards the table.

"Calling here and looking out the window." Han Gang pointed.

Huang Shang did what he said. When he looked out the window, an old plum tree in the courtyard jumped in front of him in the mirror, and his body couldn't help but tilt. The lens of the brass cylinder moved, and every grass, wood, brick and tiles in the courtyard were all pulled down by something that was not much different from the main body of the microscope.

Putting the brass cylinder down from his eyes, Huang Shang asked in a daze, "Dragon Picture, this is..."

"This thing is a cave, and the emperor named it Qianli Mirror." Han Gang said, shaking his head. Zhao Xu was still uncreative in his name. "This name is a bit exaggerated, and it is actually more accurate to call it a telescope. But since the emperor has named it, it's better to call it that. A microscope can make people see clearly, and a Qianli Mirror can make things in the distance still in front of him. Does Mian Zhong know the truth?"

Huang Shang looked upside down a few times: "It's the overlap of convex lenses and concave lenses."

"It's not that you can just fold two lenses into a telescope, otherwise it wouldn't be until today that someone invented it. Metaphysics is called Tao, and Tao is the principle. Once you understand the truth, you will return to the metaphysical instrument. After you understand the principle of the Qianli Miles, you can create a farther and clearer look." Han Gang took the Qianli Miles from Huang Shang's hand, "This thing is the most useful to match the spacecraft. But this time it won't be used. See who has the greatest contribution to this battle and is the best bet."

Han Gang's generosity surprised Huang Shang very much, "This is a gift from the emperor..."

"The sword is given to the martyrs, the red pink is given to the beautiful woman. The Qianli Mirror is better to the generals who lead the army. I hope the thief is tied to me without relying on the Qianli Mirror." Han Gang didn't care. "As long as the principles contained in the Qianli Mirror can be obtained, it can be rewarded by the emperor. At that time, the Qianli Mirror will become an ordinary thing and will be equipped on every spacecraft."
