Although Daliang is a martial country, due to the geographical environment, it is impossible to raise war horses on a large scale, so that the cavalry is pitiful, and most of them are based on foot combat.

Infantry battles faced with cavalry, without relying on terrain or city defenses, faced with cavalry, almost one-sided slaughter.

Daliang and Beidi have been at war for decades, and most of them have suffered losses, and the border soldiers have long had no fighting spirit.

Not to mention the frontal defeat of the Beidi cavalry, I am afraid that the two armies will face each other, and they will collapse at the first touch.

Seeing Qin Tianhu pick up the whip, Qin Feng jumped out of the distance, standing in the courtyard, ready to flee for his life at any time, but he refused to admit defeat:

"Sergeant Daliang, it's not just the border army, there are heavy troops hoarding in all towns, since the border army is instigated, then send a brave division to replace it.

"Not to mention the frontal defeat of the Beidi cavalry, as long as you face the enemy cavalry charge and revitalize it, it is enough.

"Replace basic infantry with archers, and improve your armament to create a powerful crossbow. The 5,000 archers were an integrated army, and the first two rows were killed and wounded from a distance with strong crossbows, and all the cavalry that entered the 800 infantry had to be covered by a rain of strong crossbows and arrows.

"When the enemy's cavalry has rushed to three hundred paces, three, four, or five columns of archers, progressive firing can not only effectively kill and wound the enemy's strength, but also disrupt the local charge formation, and weaken the impact of the first wave of cavalry as much as possible.

"In front of the archers, there are three rows of foot battles, the first row holds heavy shields, the second row sets up spears, and the third row sets up short spears......

"Ahem, anyway, I don't believe it, cavalry can't fly overhead.

"In such a formation, only the two wings are weak in defense, so only the two wings need to be guarded, which is enough to defeat the cavalry.

"It is only necessary to set up a team on each wing, with long weapons such as simple knives, bending knives, and falling knives, supplemented by short weapons, to immediately resolve the weaknesses of the two wings.

"What kind of bullshit cavalry, dare to face it head-on, it will be called if there is no return, and the whole army will be annihilated!

"If guerrilla tactics are adopted, it is okay to attack in small groups, and strong crossbows and longbows can kill and injure rangers beyond the effective range of the opponent.

"Why, I'm a girder archer, standing on the ground, and no one has been able to shoot accurately on a horse?

"If the enemy cavalry surrounds the rear, the long knife team on both wings of my large array will go around the rear in time to return to the defense. ”

Qin Feng said a lot, beaming, thinking that he had watched so many military movies, seen so many military enthusiasts bragging on the Internet, and played so many Three Kingdoms War games, could he not compare to a few barbarian tribes?

Seeing Qin Feng talking, Qin Tianhu's original face became more and more disdainful, and he was just about to scold and let this stinky boy who talks nonsense and satisfies nonsense get out.

But then, his eyes gradually widened.

Qin Feng's words just now seem to be rumors and words on paper, but if you think about it carefully, this set of tactical arrangements is extremely perfect!

If it can be reorganized and give full play to its strengths, it will be a complete set of tactical and military strategies, and it can be said to be invincible in dealing with cavalry!

It's a pity that Qin Feng's tactics have a fatal loophole, that is, they can only form a formation to resist, and they can't take advantage of the victory to pursue.

After all, cavalry has always been the weakness of the girder.

Moreover, the Beidi cavalry fed the war with war.

It only needs to make the other side return in vain, which is actually equivalent to victory in the war.

In this way, this set of tactics is extremely desirable!

At the same time, Qin Tianhu grabbed a key point and rushed to Qin Feng, who was hiding in the courtyard and refused to approach, and asked angrily: "What are the strong crossbows and Mo knives?"

According to the memories of his previous life, this world is not only backward in literature, but also in terms of military affairs, and it is more than one grade behind Qin Feng's world.

The arms of the army can be roughly divided into three types: sword soldiers, short archers, and cavalry.

In terms of archers, the archers of the girder are literal archers, except for bows and arrows, there are no other weapons, once they are close to the enemy, they can basically only wait for death.

Unlike the archers in their own world, in addition to bows and arrows, they are also equipped with auxiliary weapons such as knives and axes, spears, and knives.

Once the enemy rushes to the front, every archer can be instantly transformed into a melee foot soldier.

Seeing Qin Tianhu staring at him, Qin Feng didn't dare to approach rashly, and smiled all over his face: "Pu Dao and Qiang crossbow, I can't say it in a few words, if the father wants to know, the child will draw it, and you can see it at a glance." But ......"

"Father needs to put the whip down first. ”

Seeing Qin Feng's timid and cowardly appearance, Qin Tianhu was angry.

However, in order to find out what the Pu Daoqiang crossbow was, or patiently, he threw the whip aside: "You come here." ”

Finally spared the pain of flesh and skin, Qin Feng instantly burst into joy, and jumped into the house with the steps of the six relatives who did not recognize him, and Qin Tianhu looked at it with a black face.

Qin Feng took the pen and paper handed by Liu Hongyan, almost half of his body was lying on the table, because he had not practiced calligraphy, he simply held the brush upside down in his hand, tilted his head and thought for a while, and then drew on the paper randomly.

The simple knife is easy to draw, and it will be done in three or two clicks.

This strong crossbow is more complicated, Qin Feng thought about it for a long time before he distorted it and drew some important parts.

Then he threw the brush aside, ran into the yard and picked up a branch, which was dipped in ink to use as a pencil, and marked the name and function of each part under it.

Finally, write down the simple principle clearly.

Qin Feng sandwiched the branch between his middle and index fingers, trembled, and his face was full of pride: "It's done." ”

Liu Hongyan couldn't help but glance at him: "The poetry is right, but it is extremely amazing, it is your painting, it is really ...... It's too stumbling. ”

Qin Feng shrugged his shoulders and disagreed: "What's wrong with being ugly? ”

Qin Tianhu stared at the diagram, pondered for a long time, and slowly turned his head to look at Qin Feng: "How did you know about these two things?"

How can this be explained? Could it be that he learned it from a military documentary? It will definitely be regarded as a brain dead by Qin Tianhu and kicked out.

Qin Feng simply exerted his shameless plagiarism spirit, his face was not red and his heart did not beat: "Of course I invented it myself, I used to be idle, so I played around by myself, and I don't know if it works......"

Before Qin Feng finished speaking, he was slapped in the face.

Qin Tianhu's eyes widened, and he was angry: "You loser, these two weapons, once they are created, they will be magic weapons in the army, if you take them out earlier, how can my border army suffer so many losses?"

After scolding, Qin Tianhu put the diagram under his armpit and entered the lounge built into the study with a black face.

Qin Feng tiptoed over and listened through the crack in the door, Qin Tianhu deliberately lowered his voice, but he still couldn't help the excitement in his heart:

"It is worthy of being my Qin Tianhu's son, sure enough, it is a tiger father without a dog, with these two weapons, supplemented by military strategies, I will definitely be able to make Beidi come and go, and raise my Liang Guowei!"
