The steel crossbow in Li's hand is no stranger to him.

In addition to having no sight, it was almost the replica of the composite steel crossbow that Yan Liben made for him in order to bet with the dandies.

Li Qieyou didn't expect that for more than a year, Li Er ordered the supervisor to make this composite steel crossbow with all his strength, and personally named it "Qingtian crossbow"

Thanks to Li Qieyou's hydraulic press, otherwise Datang really couldn't get so much refined steel to make this composite steel crossbow.

Originally, the Tang Dynasty did not pay attention to crossbows. In the art of war of Li Jing, the Duke of the Tang Dynasty, the proportion of crossbow bearers among soldiers was the lowest, only about 14%. For each army, the proportion of crossbows is even lower, usually only 10%.

In addition to the Jianghuai crossbow, the status of the crossbow in the Tang Dynasty was far lower than that of the bow and arrow.

The reason is that the crossbow has a short range, slow loading speed, good defense and poor attack.

The generals of the Tang Dynasty did not hold much hope for the use of crossbows as a weapon to restrain the cavalry from rushing with long-range fire.

Among the Tang army, Mudao and cavalry were the most important arms.

But the composite steel crossbow made by Li forget worry not only has a long range, but also has a booster on the upper chord, which is not only fast but also labor-saving.

Li Er, as the emperor of the horse, laid down half of the Tang Dynasty. How can he not see the role of the steel crossbow.

Therefore, even though it was very expensive to build a composite steel crossbow, he still clenched his teeth and ordered the supervisor to build a large number of crossbows and began to equip the army in batches.

Now, among the 10000 Tang army iron cavalry led by Li forget worry, there are 2000 crossbow men equipped with "giant crossbow".

In fact, it is not correct to call these 10000 Tang troops iron cavalry.

Although they all marched on horseback, only more than 2000 of them were real cavalry. The remaining 8000 people and horses should be called horseback infantry.

Unlike Xue yantuo's dismounted infantry array, these dismounted infantry of the Tang army are professional infantry, and horses are only their "means of transportation" for marching. When fighting, they dismount and fight on foot.

According to Li Weigong's art of war, among the field troops of the Tang army, the proportion of combat troops is 70%, and the rest are all kinds of medical, logistics and auxiliary personnel.

In other words, the 10000 troops led by Li Qieyou have 7000 soldiers.

Among them, there are 2000 cavalry, 2000 crossbow men and 2000 jumping soldiers, that is, sword and shield men. As well as the Tang army's most elite sharp knife, a thousand strangers.

Originally, according to Li's idea before forgetting worry, the war with Jie Li was very simple. You only need to copy Li Ji's tactics.

Use five thousand infantry to deal with Xue yantuo's dismounted cavalry array, and then two thousand cavalry will bypass the rear and raid Xue yantuo's rear cavalry. As long as you kill Xue yantuo's horses, you'll cut off the feet of 50000 troops. At that time, these dismounted cavalry of Xue yantuo will become meat on the chopping board. You can do whatever the Tang army wants.

But Li forgot to worry about it, but shook his head and denied the tactic.

It's not inappropriate, but he doesn't intend to expose this tactic so early.

Xue yantuo's dismounted cavalry array is not worth mentioning. It's quite an idiot. But Li forgets his worries. He really has the idea of going to yudujun mountain and catching Yi man Khan alive.

In this way, it would be inappropriate to defeat Jie Li Peng with this set of tactics.

After all, Xue yantuo's people are not idiots. After he defeated Jie Lipeng in this way, it's not so easy to deal with Xue yantuo's remaining 150000 troops.

As long as Xue yantuo left enough cavalry to guard the horses of the rear army, he could not defeat Xue yantuo's more than 100000 troops with 10000 men and horses.

Therefore, Li forgets sorrow and needs to think of another way. He should not only defeat the 50000 troops opposite Jie Li, but also not expose the weakness of Xue yantuo's dismounted cavalry array.

It's really not easy to confront the 50000 troops of Jie Li with 10000 troops. If you don't do it well, you will be self defeating.

But since Li forgot to worry and found that Li Er had allocated a large-scale composite steel crossbow to the army, he had enough confidence.

With these two thousand composite steel crossbows alone, the enemy can shoot without fighting back. In addition, the invincible stranger swordsman of the Tang Dynasty pressed the array. Even if Jie Li's strength was five times that of him, there was nothing to worry about.

An ordinary crossbow has a firing distance of only 200 steps and a direct firing distance of 70 or 80 steps. The "giant crossbows" equipped by the Tang Army today are equivalent to four stone crossbows, with a firing distance of almost 400 steps and a direct range of more than 200 steps.

With this crossbow, Li Qieyou was able to shoot a 300 meter wild boar with rough skin and thick meat. Then the effect was the same against Xue yantuo's soldiers.

In other words, relying only on the ultra long range of the composite steel crossbow is no less than "dimensionality reduction strike" for Xue yantuo people.

Although Li forget worry is not a soldier, but as a military fan, he also knows what it means to master the range advantage and can constantly attack and kill the enemy outside the enemy's attack range.

The elimination of bows and arrows by fire guns is the best example.

In this era, the power of composite steel crossbow is almost the same as that of fire gun, and it can even be said that it is stronger than that of early fire gun.

At least, those shotguns in Manchu could not accurately snipe the enemy at a distance of 300 meters.

The early fire gun and composite steel crossbow must have been designed by Li forgetful, which not only makes the stringing speed faster, but also stimulates faster. And because the steel cable is used as the crossbow string, it is not even affected by the weather.

The composite steel crossbow has only one disadvantage compared with the early fire gun, that is, it is expensive!

Both the cost of making steel crossbows and the consumption of crossbows are too expensive compared with gunpowder and lead pills.

Fortunately, the Tang Dynasty is becoming more and more powerful, otherwise Li Er may not be able to afford so many giant crossbows.

However, the use of composite steel crossbow in Datang has some misunderstandings.

Just like when the tank was just invented, the use of it in western countries was scattered to various divisions and regiments to cooperate with infantry attacks. It was not until World War II that tanks began to be used intensively and became the king of land warfare.

The Tang army used a composite steel crossbow, but it was no different from ordinary crossbow men.

But in Li's opinion, the tactics that can give full play to the power of the composite steel crossbow are the rope gun tactics of the 16th century, three-stage shooting!

Although the composite steel crossbow is equipped with a stringer, the shooting speed is not too fast.

In this way, in order to give full play to the maximum power of the steel crossbow and avoid the disadvantage of unsustainable shooting, three-stage shooting is very necessary.

Divide the crossbow men into three teams. The three teams take turns to string and shoot, which can triple the efficiency of the composite steel crossbow!

In this regard, Li Qieyou is very confident.

However, Li's confidence does not mean that Mito and Chumo have confidence.

Even though they had great confidence in the combat effectiveness of the Tang army's iron cavalry, in the face of five times their own enemies, whether they were dandies or Mito, or those school captains and generals in the army, they all beat drums in their hearts.

Even Mito and many times persuaded Li forgetful to withdraw, but they found Li forgetful's refusal.

In this regard, Mito is also very helpless. He can only secretly tell his Baiqi spy to be ready. If the Tang army is defeated, even if it is tied, he will have to save Li forgetful, the king of Qin.

After Jie Li Peng finally decided to die with Li forget worry, the two sides set up camps on the grassland and confronted each other ten miles apart.

On this day, the wind is light and the clouds are light, the mountain rain is coming, and the wind is full of buildings. It is really a good day to kill and set fire. Both sides agreed to start war today.

The first horn of the Tang army blew, and all schools of the Tang army gathered people to ride as a team!

The second horn blew, and the flags and spears were raised one after another!

The third horn blew, and the Tang army marched out of the camp to meet the enemy. The wind rolled the flags!

When the war drum sounded, Tang Jun and Xue yantuo stepped out of the attack at the same time
