Warrior in Turbulent Han Dynasty

It was a quiet night, but Guo Shao knew that the enemy soldiers were approaching, and it was expected that they would appear nearby tomorrow morning.

The soldiers who were not on duty all rested early, and at this time even the guards of the Chinese army were standing or sitting. Guo Shao looked out from the open tent and saw a soldier sitting beside the fire, burying his head in his needle and thread, silently sewing his clothes. The soldier was very strong, but he was very young, he looked only in his teens.

Guo Shao reached out and rubbed his neck, and continued to write calculations on the paper on the simple chopping board.

Not long after the flat-firing copper cannon was made, there was a cannon watch. The so-called gun table is to make a table after calculating and testing the size of the gun, the amount of charge, and the weight of the iron shot using the parabolic formula to compare the range of each elevation angle.

However, this gun table is based on the flat ground table. Now Guo Shao is temporarily calculating the gun meter when the slope is more than ten degrees. Because of time constraints, he just set up camp today, so he has not yet calculated it when it gets dark.

...The original flat gun watch was made at the Tokyo school.

First calculate the acceleration of gravity. The data in the original formula cannot be used, because the conversion value between the unit of meter and second and the actual measurement cannot be found. The method is to re-experiment. The measurement of time is an hourglass with a scale, with the unit of a finger (approximately equal to seconds); the unit of length is zhang, chi, inch, minute, centimeter, millimeter, and silk. Of course, the so-called precision units behind can be ignored. With the current artillery technology and measuring tools, a unit that is too small is meaningless at all. The acceleration of gravity can be calculated by using the time and height measurement of the iron ball thrown from the pagoda, and taking the average value repeatedly.

Then there is the calculation of the initial velocity vector generated under the elevation angle, which is also very simple. The elevation angle uses a wooden protractor, and the trigonometric function value only needs to draw a triangle model according to the angle, and multiply and divide by the length of each side figure.

The gun watch made in this way not only has a simple comparison table, but also can set formulas; if you find an angle that is not on the gun watch temporarily, you can quickly set the formula to calculate it on the spot.

...When the actual battlefield has a slope, it can also be calculated with the basic formula of kinematics to form a new gun table.

As for the measurement of the range length of the battlefield, Guo Shao probably remembered that gun mirrors were used in modern times; but now obviously there is no such thing, and it cannot be done. His method is more stupid.

Two methods, one is to choose those people with a strong sense of distance to use their eyes to estimate, such as those who used to observe the distance for the catapult carts on the city wall when defending the city. The second is to use a rope to measure the integer distance on the battlefield, nail wooden stakes, and use those wooden stakes as a reference when starting a battle.

Now there are many wooden piles on the slope in front, which were nailed during the day, sparsely. It is estimated that the enemy army does not know what to use it for, because it has no defensive effect at all.

Just then, a person approached. Guo Shao was instinctively more vigilant in unfamiliar places, looked up, and found that a scribe in a round collar and green robe was bringing hot tea.

He ignored it, but suddenly remembered something, raised his head and asked, "Do you know how to read and write?"

The scribe hurriedly bowed and said, "Go back to Your Majesty, the villain will."

Guo Shao immediately beckoned over: "Come and help me calculate."

The clerk stepped forward cautiously, glanced at the ghost-like symbols (with various symbols and Arabic numerals) on the case, and looked like he was about to cry.

Guo Shao looked up and said, "Don't worry, I will teach you to use the calculation process, you just need to follow the calculation process."

Guo Shao chatted with him for a while, and the scribe gradually realized that it really only needs to add, subtract, multiply and divide specific numbers. The scribe left the tent again and took a little abacus.

Soon there was a skillful and agile "crack" sound in the tent of the Chinese army, and the scribe calculated very quickly... The abacus is like an ancient calculator, and its efficiency is much higher than that of the pen. Guo Shao deeply admired it.

... nothing happened overnight. Just after dawn, Guo Shao woke up to the familiar rhythm of drums outside the barracks, got up and put on his armor. A group of personal soldiers and servants took care of him.

Guo Shao asked, "Has the enemy army arrived?"

The clerk who helped him do the math last night said: "Return to Your Majesty, the vanguard arrived as scheduled and occupied the high mountain slope to the west."

Guo Shao stretched out his arms, and the eunuch and the male servant hurriedly put on him the clean linen with green salt washing and fragrance. Guo Shao's expression is calm and calm, his eyes are calm but sharp, and his spirit is adjusted to the best state.

He looked very calm, and asked the clerk, "By the way, I forgot to ask you last night, what's your name?"

The enemy soldiers approached under his nose, and the emperor was still in the mood to care about a small official, and his calmness infected everyone.

The clerk hurriedly replied: "Responding to your majesty, the villain is called Zhang Yin, and he is from Western Shu."

Guo Shaodao: "Your official language is quite good."

With the help of everyone, Guo Shao quickly put on the refined plate armor and fastened the dark purple cloak. He is not yellow on the battlefield, it is too bright, and it is easy to attract the attention of enemy soldiers under special circumstances.

A belt with a gold buckle was tied around his waist, and Guo Shao picked up his sword and put it on. Then I washed and ate half full.

He walked out of the tent neatly, and first stood on the slope to observe for a while. At this time, the sky was getting brighter. In the early morning of early spring, the valley was still shrouded in a light milky white mist. Guo Shao looked up at the sky. The weather today is fine.

There was no dance on the top of the mountain to the west. Guo Shao looked over and could see flags and figures standing on it.

Most of the people who stood on high places before the war were the commanders-in-chief of the coalition forces. Guo Shao had been there yesterday, maybe the footprints are still there, obviously guessing that Li Yiyin might be there too, Guo Shao felt very close in his heart.

Different people stand on the same piece of land, and their positions will be different. What is Li Yiyin thinking now?

Guo Shao watched for a while, and the generals came to the central army one after another. The Forbidden Army still retains a lot of their battle formation habits over the years, first coming to the general, and then deploying the battle formation at the end.

Nearly a hundred people came, and almost all the generals above the commander arrived. While watching the battle formation on the opposite side, everyone waited for Guo Shao's order.

"It was discussed before the army last night, and everything was deployed according to the original plan." Guo Shao said.

At this time, the generals gradually quieted down.

Guo Shaodao: "According to the actual situation before the battle, the generals can make reasonable decisions on the fly. However, without permission, copper artillery and matchlock guns are not allowed! Remember clearly, the signal for using firearms is "Ambush from Ten Sides"; the signal for counterattack is "General's Order"!"

The generals shouted and responded one after another.

Guo Shao paused. Xindao, a decisive battle like this can only happen if the two sides are willing. If the Dangxiang Khitan coalition forces are unwilling, can they concentrate their troops here? This is an opportunity. Guo Shao is focusing on the cavalry of the coalition army... especially the iron cavalry of the Liao army, because in his eyes, only the fine cavalry of the Liao army can be regarded as a qualified and organized cavalry army!

It is necessary to lure the fine cavalry of the Liao army to come up before the war can really begin.

Guo Shao's expression became solemn, and he said again: "The Forbidden Army is composed of the most capable sons and daughters in Kyushu. The equipment is the best in food and clothing. They are the people's fat and people's anointing of countless Han people!"

The words suddenly became serious, and the generals stood upright in awe. The idea of ​​putting the people first was born in the Tang Dynasty, and Guo Shao's words are still very down-to-earth.

Guo Shaolang said in a loud voice: "Your sons and lords came here not to make a fool of yourself, but for the face of the Han family. Don't disappoint the ardent expectations of me and the common people. For dignity, for the protection of the country and the people, for every inch of land left by the ancestors, I hope you will fight the enemy!"

People responded.

Guo Shao didn't say much after hearing this, and ordered: "Prepare for war!"

The generals shouted loudly: "Serve the emperor!" "God bless the emperor, live forever!"

...

All over the mountains and plains are troops in formations. Looking at the momentum ahead, Yang Gun said from the purge of the army, "The number of enemies is only one-third of ours, but this is a fierce battle."

The total number of Xu Junbu cavalry here is only more than 40,000, while the coalition army is about 120,000!

Li Yiyin said: "Xu Jun came here first, why didn't he choose the mountain we occupy, but the place opposite?"

Yang Dagon also didn't understand at all, and only said: "But the opposite side is open, and we can have a good fight!"

The coalition troops arrived at the battlefield one after another in mighty footsteps. The momentum was even greater, and the numerous troops and horses spread out horizontally. Gradually, the situation seemed to form a semi-arc, forming a semi-encircled state on the sides of Xu Jun.

More than 160,000 horses gathered in this place, the noise among the ravines was abnormal, the flags were like clouds, and the scene was very grand and spectacular.

The two sides were already clashing in the ravine between the two mountains, when the figure of a knight drawing a bow crossed in the distance.

The coalition forces had an absolute advantage in numbers, and both Yang Gun and Li Yiyin decided to take the initiative to attack. Yang Gun suggested: "The front slope is the slowest. The infantry of the front army can approach and form an formation, and then send out infantry to attack. The cavalry guards behind the two wings and stands still.

Although preparations and training have been made, the horses of the party army may not be comfortable in the face of the explosion of firearms. It is most appropriate to use the infantry to face the enemy's infantry phalanx first. "

Although Li Yiyin was the supreme commander of the main force, he also believed in the experience of the Liao army veteran, so he adopted the suggestion.

Yang Gun said again: "Xu's army is smaller in number, but the army's appearance is clean and tidy, and it can't be attacked at one time. You can change people and horses to attack in turn."

After some preparations, the Dangxiang infantry moved forward from the hillside. They were also a phalanx formed by groups of people, with different armors, many of them carried bows and arrows, and various weapons, but each of them also had a lot of strength.

Hengshan produces iron, and the party's infantry has a high rate of armor, but it is obviously unable to organize a blacksmith workshop to process the armor. The armor worn by the soldiers is messy, and they are all self-made at home.

Li Yiyin is still very confident. It is true that it is not enough to fight well in battle, it depends on one's bravery!

A large area of ​​infantry spread down the mountain, like a black mountain torrent. Li Yiyin was very excited and nervous watching this spectacular scene. Everyone comes to war to win!

Between the valleys, drums and shouts roared, shaking the mountains and rivers. Li Yiyin gripped the hilt of the sword so hard that her knuckles turned white.
