The sound of horses' hooves sounded in front of the Jinning City Ya, and with the ink-drenched military order, a general of the Hedong Army stepped on their mounts and rushed to their battlefield.

The whip wielding in the rider's palm was no longer visible, leaving only a faint figure, and Huang Xiang watched the last general leave the city. The tension before the war, like a heavy bluestone, was inexplicably pressed on my heart.

At the time of Yanmen Pass, Huang Shang still felt like a bystander. But this time, he participated in the whole process of encircling and suppressing the bandits. Although the enemy was only a few thousand, after in-depth contact with every aspect of the war, Huang Sheng realized how cumbersome it was to organize a battle.

Weather, geography, personnel, grain, weapons, and enemy conditions must all be taken into account. Moreover, in the planning and planning of the pre-war period, it was necessary to take into account the balance of the relationship between the schools and the forces of the school, so as to stimulate their greatest will to fight, and at the same time, not to let them become presumptuous for the sake of merit. It is ten times more difficult to grasp people's hearts than the mobilization of materials.

A war is by no means a cold text that exists in the history books, such as great victories, great defeats, victories, and defeats, and all the people involved in it are living people.

Watching a famous general set off with the belief that he would win, no one could have predicted how many of them would return safely. As the staff involved in the scheme, their lives may well be ended by their own wrong words.

Huang Shang's heart was depressed, and when he returned to the inner hall, he saw that Zhi Keshi was transcribing military orders.

The Qi scholars who served as Han Gang's staff members, all of them boasted of being full of poetry and books, and when drafting military orders for Han Gang, they inevitably brought a sour atmosphere, and there were even several articles at the beginning. After being taught a few times by Han Gang, the four or six styles disappeared, but even Huang Shang wrote the same, it still seemed too literary, and some words were easy to confuse the already illiterate generals and their low-level staff.

When drafting the official document, Han Gang asked for it. In the past, when he issued several regulations and books on medical skills, he would rather lose their cumbersomeness, never pursue the literary elegance of diction, and never use words to hurt them. So it is not surprising that when he puts his requirements on military orders.

Han Gang once said that the words used in official documents and regulations in the army must be precise and unambiguous, and at the same time, they must be easy to understand, so as not to misunderstand the people who accept the orders. This is a general rule in the army, not a rule set by Han Gang, but few of the civil servants in charge of the military are willing to damage their face and be ridiculed for their literary talents, just so that the generals below will not misread the order.

The errand that Zhi Keshi is doing now is to re-translate some drafts of military orders that are too obscure to the point of causing many ambiguities, and then submit them to Han Gang for confirmation, and then send them away.

Huang Shang came back and saw that Zhi Keshi was so busy that he didn't even have time to speak, so he didn't bother him. But Zhi Keshi heard Huang Shang's movement, but put down the pen, "Mian Zhong, everyone has been sent away?" ”

Huang Sheng nodded: "All out of the city,"

Zhi Keshi raised his eyes and looked at Huang Sheng again, "Brother Mian Zhong, what did the imperial court say to you before you went to war?" How can I see that you are in a mood right now. ”

Huang Shang paused for a moment, thought about it, and said his feelings to his new friend succinctly.

“…… Just get used to it. After hearing this, Zhi Keshi said very carelessly, and regarded it as an admonition.

It's just that Huang Sheng saw his attitude and became very shocked. I didn't expect that Zhi Keshi, a kind person who usually reduces his-for-tat confrontation with others, has such an attitude towards war.

Zhe Keshi didn't have time, but he was busy now, and he said without raising his head, "Since I have eaten this mouthful of food, I am used to dying on the battlefield and watching too much." Of the sixteen brothers of the grandparents, only one of them is now alone. Of the remaining fifteen uncles and uncles, six died on various battlefields, three died from the recurrence of old wounds, and the rest were also all kinds of diseases sooner or later, and only the first grandfather died in his life. At this point, you can ask the dragon figure. He started from the northwest frontier with Wang Xianggong, and at the beginning, he had fewer people than you and me, and he was closer to the generals and colonels who went into battle. ”

"Not everyone is as good as Longtu." Huang Sheng sighed, but walked towards Han Gang's living room. It wasn't to ask Han Gang's mental journey—he wasn't going to ask—but to go back and pay the order.

Huang Sheng entered the hall after his name, Han Gang was looking at a letter, and there was a brass cylinder on his desk, something that Huang Sheng had never seen before.

"Everyone's gone?" Han Gang put down the letter in his hand, and his question was almost the same as Fang Cai's folding.

"It's all gone." Huang Sheng nodded, "I left very happily, and no one hesitated to delay." ”

“…… They all want to be rewarded for their meritorious service as soon as possible. ”

People die for money, birds die for food, this is the inevitable result. Huang Shang suddenly, the heavy feeling suddenly disappeared a little. Then he laughed and said to Han Gang: "With the dragon plan to make these arrangements, the obstruction thief will inevitably be unable to escape, so that in the first half of the year, the news of the annexation of the grassland departments by the northern obstruction should be able to reach the Taiyuan Mansion." ”

"It's not as simple as it says." Han Gang shook his head, "What do you think we can think of, Yelu Yixin can't think of?" As a traitor in charge of the Liao State, he is far more than us by a hundred, a thousand, or even ten thousand times stronger than us in understanding the situation in the Liao State. Since the West Blockade Bu went south to help the Western Xia, then to prevent the North Blockade Bu from taking advantage of the fire to rob, with Yelu Yixin's intelligence, will he not make preparations in this regard? He laughed, "It's just that in a few days, I will hear that the father of Da Liao Shang will plan and fight back the northern blockade that is going south to annex the western divisions, or even wipe them out, I won't be too surprised." ”

“…… Why did Longtu do it?"

"If you don't do anything, you will never get results. Only by doing it will you have a chance to win a success. ”

"Success? …… Longtu's success is to make the blood debt of the thief repay? ”

"Yes, blood debt." Han Gang pursed his lips, his eyes became deeper, "Since I have seen the tragedy in Yongzhou, I can only repay the blood debt left by the barbarians from all over the world in my Han Realm. ”

Huang Sheng can understand Han Gang's mood change very well.

Due to Han Gang's dominance, all the Jiaozhi men have been tortured so far and become slaves of the Dongman in Guangxi, planting sugarcane and rice for the Dongman who divided the land of Jiaozhou. He still remembers that a friend once pointed to the snow-white Jiaozhou sugar and said, don't look at these Jiaozhou sugars are as white as snow, but they are actually full of blood.

But now, after Huang Sheng went to check a village that had been breached by the Divination Blockers, when he heard someone crying out for the slaughter of the Jiaozhi people in Yongzhou, he would definitely scold him in person.

Han Gang raised his eyes and asked Huang Shang, "Mian Zhongke still remembers the fortieth biography of the Hanshu?" ”

Huang Shang raised his eyebrows: "Those who commit strong men will be punished even if they are far away?!" ”

"Ahh That's right. Han Gang smiled, "Although it is too much to talk about people now, there are many times to attract scolding." But in the hundred volumes of Hanshu, my favorite is still this sentence. 'It is advisable to hang your head in the barbarian mansion to show that you are thousands of miles, and those who commit strong men 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 at the end of the volume, among the several biographies in this volume, Chen Tang's biography was the longest one, even longer than the other articles combined. The eldest brother of Ban Zhongsheng [Ban Chao] must have been difficult to restrain his pen when he was writing Chen Tang's biography. ”

Huang Shang nodded. Chen Tang's sentence is just a moment of excitement in ordinary times, but at the moment when the war is blazing, it can't help but touch people's hearts.

"Zou Yan used to have the saying of big Kyushu and small Kyushu. Looking at my land in China, it is only a red county in Shenzhou. Outside of China, I don't know how much land and population there is. Under the whole world, it is not the king's land, and the shore of the land is not the king's minister. Han Tang worked hard for this, but the next one really didn't work. The Central Plains infighting in the Three Kingdoms and the Five Seasons, doing a dojo in a screw shell, is too petty. The world is so big that it's not just limited to Kyushu. Therefore, reading the biography of Chen Tang and others is much happier than the history of the Five Dynasties. Hanshu can drink wine, and the history of the old and new five dynasties will only want people to smash the teacup. ”

Huang Shang was inconvenient to follow Han Gang to say that the history books were not, and he was not qualified enough, so he diverted the topic: "The earth is vast, I remember that the bachelor also said it in the past." It was mentioned in "Gui Window Cong Tan" that the earth is spherical, and because of its inner diameter, the outer circumference is nearly 100,000 li. Because of this, people living on it do not realize that it is actually spherical. ”

"How to determine whether the earth is spherical has long been explained, but the lack of accurate numbers seems to be speculation. In the meantime, when trying to accurately calculate the length of the meridian line, the monks of the Tang Dynasty had calculated it, but the error was too great. Qi science should be truth-seeking, realistic and reasonable. To learn from things, to seek is a true and unmistakable word of 'reason'. ”

Organizing people to measure the meridian by hand, Han Gang was not a whim. In Kansai, Cheng Yi had just returned to Luoyang after more than a year of lecturing. He has been in Guanzhong for more than a year, and he has instilled Cheng Menluo Xue into many Guan sergeants. Su Yu is still in Hengqu Academy to support the overall situation, but he is powerless to fight against Cheng Yi. Han Gang could not just stuff his fellow disciples into his shogunate, he had to achieve new academic achievements or prove his unique views. It wasn't imminent, but there wasn't much time left for him.

Han Gang thought about it, picked up the brass cylinder on the table and handed it to Huang Shang: "This is a new thing sent by the Son of Heaven to support the military, and it was only recently presented to the Son of Heaven by an optician in the general's courtyard. ”

Huang Shang took it and fiddled with it. It was found that this brass cylinder was a simple two-section sleeve with a crystal lens on the front and back.

"A microscope?" He asked, pulling the cylinder away with ease. One end to himself, the other to the table.

"Turn around and look out the window." Han Gang pointed.

Huang Shang did as he was told. Looking out the window, an old plum in the courtyard jumped in front of him in the mirror, and his body couldn't help but lean back. The lens of the brass cylinder moved, and every grass and tree, brick and tile in the courtyard was pulled down by this thing whose shape was not much different from the main body of the microscope.

Putting the brass cylinder down from his eyes, Huang Sheng asked dumbfounded, "Long Tu, this is ......"

"This thing is a thousand miles of candles, and the Son of Heaven named it a clairvoyant mirror." Han Gang shook his head as he spoke, Zhao Ji still didn't have any creativity in coming up with a name, "This name is exaggerated, it's actually more accurate to call it a telescope." But since the Son of Heaven gave this name, he called it so. A microscope can make people see clearly, and a clairvoyant can make things in the distance still in front of you. Can Mian Zhong know the truth of the Dao? ”

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

"It's not something that can be made into a telescope by stacking two lenses on top of each other, otherwise no one would have invented it today. Metaphysically speaking, the Tao is the truth. When you understand the truth, you return to the metaphysical instrument. If you understand the principle of the clairvoyant, you will be able to see farther and more clearly. Han Gang took the clairvoyant mirror from Huang Shang's hand, "This thing is most useful when paired with a spaceship. But this time it won't be needed. Let's see who has the most credit in this battle, and it's good to be a lottery leader. ”

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

"The sword is given to the martyrs, the pink is given to the beauties, and the clairie mirror is still for the generals who lead the army. I wish the thief had been tied up in front of me, not by a clairvoyant. Han Gang didn't care, "As long as you can find out the truth contained in the Thousand Miles Mirror, you can repay the Son of Heaven." When the time comes, the clairvoyant mirror will become an ordinary thing, and every spacecraft can be equipped with it. ”
