Finally finished lunch, Yang Yuanzhi still had to talk to Qiu Yizhi, but his grandson Yang Jin dragged Qiu Yizhi over: "Brother is really patient, I talked to my grandfather all morning, do you want to talk about it in the afternoon?" I have good things in my room, so my brother can go play with me! ”

Yang Jin's words really went to Qiu Yizhi's heart. As a junior, listening to the teachings of the old prime minister, he must not only put on a diligent and knowledge-seeking appearance, but also not show the slightest impatience, which is really not Qiu Yizhi's frivolous and active personality. So, Qiu Yizhi pretended to be unable to resist Yang Jin, and said "rudeness" to Yang Yuanzhi, and was dragged out of the house by Yang Jin.

The two of them walked through the garden path, and only then did they find a small house under a large thorn tree hugged by two or three people.

Yang Jin said to Qiu Yizhi: "Brother, we have arrived." He also instructed the maids and servants standing at the door of the house to stand down and not to disturb them, so he personally pushed the door and let Qiu Yizhi into the house.

Entering the house, Qiu Yizhi glanced around, and saw that the furnishings in this room were very simple, just beds, desks, and circle chairs, and it looked no different from where ordinary children sleep, but they didn't know where the "good things" in Yang Jin's mouth were.

The owner of the house, Yang Jin, the young master of the Prime Minister's Mansion, seemed to guess Qiu Yizhi's thoughts, smiled at him slyly, leaned under the bed as soon as he was a cat, and dragged out a wooden box about three feet long from under the bed with great effort, and said to Qiu Yizhi: "Good things are here, brother, open it and take a look." ”

Qiu Yizhi didn't know what Yang Jin was selling, lest he play some prank to scare himself, so he carefully opened the box and looked at it, the box was full of countless wooden villains. Qiu Yi's childlike heart was not lost, and he took out a careful look: this little man is carved from fine jujube wood, the size is an inch long, and the faces are vivid, and the wooden man in his hand is riding a horse under the crotch, holding a sword in his hand, and seems to be a general.

While Qiu Yizhi was observing, Yang Jin had already taken out the villains full of boxes, squatted on the ground and placed these villains flat on the ground one by one. Qiu Yizhi was familiar with military affairs, and at a glance he could see that Yang Jin was not fiddling with these delicate wooden figures at will, but was arranging a very orderly formation, so he stood silent, and watched the game of this young master of the Prime Minister's Mansion seriously.

After a while, Yang Jin got up and said, "Brother, give me the general in your hand!" After that, he took the wooden figure in Qiu Yizhi's hand and placed it in a pile of wooden figures, "Brother, do you think my formation is powerful?" ”

Qiu Yizhi was condescending, looked carefully, and saw that the total number of these wooden soldiers was about 500 people, infantry, cavalry, archers and other types of troops were readily available, if it was changed to a real person, it was also a very capable team.

Looking at the formation again, it is different. It turns out that the marching formation has formed a fixed position for thousands of years, which is nothing more than the infantry in front, the shooters in the rear, and the cavalry on both flanks. However, Yang Jin used these villains to line up a "long snake formation", but the difference was that the infantry, cavalry, and archers were lined up at intervals, which made Qiu Yizhi's vision refreshing.

Looking at this pile of lifelike puppet warriors, Qiu Yizhi's mind seemed to have a tense scene of the two armies facing each other on the battlefield. For a while, tens of thousands of horses and horses came and went, flesh and blood flew sideways, and Qiu Yi's ears faintly beat war drums, horns contended, and the sound of killing shook the sky, and the nostrils seemed to be filled with a choking smell of blood.

Yang Jin pulled Qiu Yizhi's sleeve vigorously and dragged him back to reality from the fantasy battlefield, but asked in his mouth, "How does my brother look at my formation?" ”

Qiu Yizhi smiled and said, "Brother, do you have pen and ink here?" ”

"Absolutely!" As Yang Jin spoke, he took rice paper and a brush from the desk in the room.

Qiu Yizhi took it, tore a piece of rice paper several feet long into pieces of paper the size of half a palm, and used a brush to draw circles, squares, triangles and other shapes on it, and explained: "This circle is an infantry, a square is a shooter, and a triangle is a cavalry." As he spoke, he spread the pieces of paper on the ground and formed a formation.

"Our army is known for its steady movements, and it adopts only an ordinary formation, that is, the infantry first, the shooters behind, and the cavalry flanks. The difference is that the infantry of Youyan Dao has heavy armor and sharp swords, and is known as the 'Dangya Battalion'; the archers behind them use excellent bows and crossbows, and the range can be compared with the Turkic cavalry archers, and the power is a few points better; the cavalry mounts on both sides are all good horses and famous horses on the steppe, and they often clash with the Turkic elites, and the horse kung fu alone is definitely not below it. Qiu Yizhi's tone was a little proud.

While speaking, one of the Qiu Yi sides slowly moved the formation forward as a whole, and said, "Our army has advanced so far, and it has reached the range of Brother Yang's archers. However, the foundation of the 'dangya battalion' is to be able to be fearless in the face of flying locust arrows, and the fraternal archers are loosely arranged, and the firepower must not be concentrated, and it cannot cause major damage to the 'dangya battalion'. As he spoke, he continued to advance a little further in the formation, and added:

"In this way, our army is advancing thirty paces, and the crossbowmen in the second row will be able to shoot at Brother Yang's army. Crossbowmen differ from archers in that they shoot arrows from their backs to the sky and are able to bypass the infantry covering in the front row, while crossbowmen shoot horizontally and are far more powerful than bows and arrows. At that time, the soldiers of the 'dangya battalion' in the front row of my front row will read the flag and order to protect their backs with shields, and they will prostrate on the ground, and the crossbowmen will naturally shoot forward without any obstacles. Brother Fang Cai said that the fire of this crossbow machine is extremely powerful, a hundred crossbowmen, a salvo, can put more than ten hoplites, if it is not wearing heavy armor, it is even more vulnerable. ”

Qiu Yizhi breathed a sigh of relief and continued: "In the little brother's array, in addition to the infantry, cavalry and archers cannot wear heavy armor, I am afraid that a few salvos will have lost most of them. Then as long as the infantry of our army calmly gets up and advances, and the cavalry outflanks the two wings, then under the superior strength of our army, I am afraid that the Yang brothers will already be defeated. ”

Yang Jin was very discouraged by Qiu Yizhi's words, and pursed a small mouth: "I have thought about the formation for such a long time, is it really so vulnerable?" ”

When Qiu Yizhi heard this, he realized that he had hurt the child's heart, scratched his head and said, "That's not what I said." The Youyan army is so well equipped and trained that there are few rivals in the world, and no matter what formation the ordinary army puts on, it is of little use. However, the formation of the little brother's research, if it is against an army with similar strength, has a great unexpected effect. Look, brother—"

Qiu Yizhi said, put a pile of pieces of paper back in place as it was, and slowly advanced the infantry, archers, and cavalry in turn: "Our army did not expect the opponent to mix and line up the horse and foot archers and enter the firing range without knowing it. As long as the brothers concentrate their bow and arrow firepower and aim at our army column to concentrate their shots, it will make our army's formation unbalanced. When our troops react and withdraw from range, the brothers can order the cavalry to charge immediately, and take advantage of the weak point that we have just shot from the side when our formation is in confusion, and break through in one fell swoop, and cut our army into two parts. ”

Qiu Yizhi took a breath and said: "At this time, the infantry in the brother army can slowly advance under the cover of the archers, and together with the cavalry that broke through our formation, they will form a front and rear attack, then the overall situation has been decided." ”

Yang Jin was a little happier when he heard this, and asked again: "Could it be that Youyan's army is invincible in the world?" ”

Qiu Yizhi shook his head and said: "If Youyan's army is invincible in the world, then it would have been out of Shanhaiguan in the north, sweeping away the Turks, and removing the great trouble for the Han Dynasty." If you want me to see it, the Turkic cavalry can be called invincible in the world. ”

As he spoke, Qiu Yizhi picked out the pieces of paper with circles and squares, put them aside, and tore a bunch of pieces of paper again to draw triangles, and said, "Brother, please see, the Turkic soldiers are all composed of cavalry. However, our army is based on infantry as the core, and a small number of cavalry play only an auxiliary role. The Turkic cavalry was light and fast, and our army marched one mile, and they ran ten miles. Even if our army concentrated its superior forces to find a decisive battle, the Turks would have already run away without a trace as long as they received the information a day in advance. If our light divisions advance, they will be able to quickly mobilize a large army and attack from all directions, and then our army will already be more than lucky. ”

Qiu Yizhi saw that the little brother in front of him, who was less than ten years old, blinked and nodded with a pair of big black and translucent eyes, but he didn't know how much he understood.

And Qiu Yizhi didn't know if he hadn't talked to his father-in-law, master, third brother Zheng Miao and other brothers for a long time today, or he was indignant that his father-in-law, who cared about his family and country and adhered to the frontier, was framed by a tricky eunuch, and he couldn't hold back when he spoke.

He continued: "Even if our army wins by chance, it will not be of much use. The Turkic steppe is extremely vast, not below the territory of the Han Dynasty, and although the forces of our army can be deterred, they have never been able to effectively control it. Even if the main force of the Turkic army is wiped out by our army, it will not take a few years to raise an equally powerful army, and the victory or defeat will be especially evident......"

When Qiu Yizhi said this, the door of Yang Jin's bedroom suddenly and slowly pushed open, and Yang Yuanzhi's old voice came: "Childe's high insight is really beyond the comprehension of metrics who have been sitting in the study for a long time. As for the generals in the army, I don't think there is anyone who can have such insight except for General Dai Luanxiang of Zuo! ”

When Qiu Yizhi heard this, he was neither surprised nor polite, but just bowed deeply to Prime Minister Yang and said, "These are all taught by my stepfather to the younger generations on weekdays. As far as the younger generation knows, since the Turkic Han Bisimi was killed by my father-in-law a few years ago, although it has stopped for some time, in the past two years, the power has risen again, and it has been constantly encroaching on the territory of the Han and Bohai States, which is really unguarded. And at the moment, there is no second person in China who can restrain the Turks, except for my father-in-law, and this is really not the time to self-destruct the Great Wall! As he spoke, he burst into tears.

Hearing this, Yang Yuanzhi was finally moved by Qiu Yizhi's words, he held a cane in his hand, stabbed the green brick under his feet, and said: "Old decay just don't want this old bone, fight this white head, and save the prince of Youyan!" ”

Yang Jin, who was ignorant on the side, seemed to hear the voice, and said excitedly: "It turns out that my brother is the righteous son of Prince Youyan!" Grandpa doesn't know how many times he has praised my brother in front of me, and the next time my brother goes to the north, he must take me with him, and our brothers will fight Tartar together! ”
