Looking at his troubled expression, Li Hang could almost guess something.

"Why, the family doesn't understand?"

The biggest pressure on people doesn't come from the outside, it's usually from the people around them.

"Hmm!" Zhao Feilong hummed in a low voice, a little lonely and a little helpless.

"Actually, this is very easy to solve, the original intention of your army was not to fight head-on, your family members are so powerful, you let them use pure archer troops to fight cavalry on the grassland!"

Li Hang rolled his eyes.

Although there are no examples of pure archers in the world beating other troops, it is also a purely defensive position, and the bow and arrow are also relatively good longbows.

And now the short bow is usually used here, and it is thankful that it can throw more than 100 meters or 300 meters.

Not to mention hand-to-hand combat abilities.

In these years, only cavalry could fight cavalry, and when it came to passive defense, that is, pikemen had a slight advantage. But in reality, in real battle, the pikemen who held off the cavalry at the cost of their lives were often the fastest to collapse.

The other party is not a fool, you are defenseless, and it is strange that Lao Tzu does not shoot you in the face.

"An army, especially an invincible army, must be perfect in all respects, whether it is infantry, light cavalry, heavy cavalry, archers, long-range troops, or even siege equipment! None of them are indispensable, once one link is missing, no matter how strong your other parts are, they will be directly destroyed! ”

In the previous life, Rome was surrounded by Hambani classmates in the classical style, mainly because the Roman legions had no cavalry.

The Roman legions were strong, and thousands of years later, riot police everywhere learned the routines of the Roman legions.

It can be said that the classic formation remains a permanent typical, but because of the lack of cavalry, it is not that it has been beaten to the north.

During the expedition to Kalai, he was beaten by the light cavalry and heavy cavalry and was about to shake out his pee.

It can be said that a unit with shortcomings is inferior to a unit without shortcomings. And this kind of army without shortcomings can easily defeat troops with shortcomings.

"You mean to train me in infantry, cavalry, archers, and siege weapons?"

"Now it's small, you just need to keep the Qubu, and when you really start to compare with those regular armies, you just need to take good care of your army, anyway, I've been collecting experience from all walks of life recently, and I think it just so happens that your military book and some ways to prepare the army can also be added." Li Hang said with a smile.

The experience and knowledge of this era, coupled with his vision thousands of years later, what kind of reaction will happen, he is very much looking forward to it, especially this kind of thing like military training, at this time can see the effect in the short term.

You can train one in a few months, and you can hold it for a while.

As for what will happen in a few months or in actual combat, this is something that generals have to worry about, not themselves.

"You want to get a war book?" Zhao Feilong looked at Li Hang with a surprised expression.

There is no doubt that these things are written through some practical experience, and you write a book written by a person who has never fought a war, can you make others believe it?

"Sum up the experience, and then experiment with the new army, you must know that the new army is different from the previous army, and the new army needs something completely new, not a collection of things that have been tested on the previous army."

Li Hang touched his chin and said.

Thinking about Li Hang's words, Zhao Feilong also nodded, what he said was not wrong, the new army really needs achievements and brand new things.

"Like this!" Li Hang took out the design drawing and put it in front of this Zhao Feilong. "In the future, I plan to popularize this kind of thing to the generals of the Great Win Dynasty!"

What Li Hang is showing is a telescope.

"What is this?"

"Something I'm working on, if it's done, can be seen hundreds of meters or even kilometers away! If you think about it, when the two armies are facing each other, you are 800 meters away, you are completely aware of the enemy's movements, and you know all about which troops have moved and which troops have withdrawn. ”

"Awesome!" Raising his eyebrows, looking at this little expert in war, Li Hang looked at him with a very good look.

"If you can really do it, it's really powerful, and if you Li Hang can do this, it will really be a blessing for me to win the dynasty."

There are only a few hundred people in the border army, and they only need to be equipped with one or two, one in the hands of the commander and one in the hands of the reconnaissance cavalry, as long as they know how to use it, let alone the enemy's movements, that is, how many people in their camp can be roughly observed and estimated from a long distance.

As long as there is this, it can really be the same as what Li Hang said, whether it is harassment or frontal combat, or defense, it is simply invincible.

As the so-called knowing oneself and knowing oneself and knowing oneself is invincible in a hundred battles, such an artifact of knowing oneself and knowing oneself will definitely not be weaker than that stirrup or something.

"How's that, awesome!" Li Hang laughed.

I took out the magnifying glass I had prepared.

This magnifying glass will convince this guy better. "Come and see this!"

I saw the words on the book in front of me, one of which was two large.

Zhao Feilong was shocked.

originally thought that this was just a hypothesis, but he didn't expect him to be able to really realize it, which surprised Zhao Feilong.

Under this approach, what Li Hang said has a high degree of credibility, not to mention that there are two lenses painted there, which means that it must be magnified and enlarged, which will definitely have such an effect.

Zhao Feilong stared at Li Hang with blazing eyes. "When will it be done?"

"In about ten days, the lenses are complete, and now the key is how to make them, it's not very difficult, this thing can be made with a bamboo tube!"

Li Hang knows very well how to do this thing, and there is another troublesome part of this thing, that is, secrecy.

How to maintain its secrecy, and be able to destroy it as soon as it is discovered or surrounded and there is no hope of breaking through.

That's the hard part.

In ancient times, there was no such statement, after all, technology does not need to be kept secret, but in modern warfare, as long as there is something that needs to be kept secret, most of them have self-destruct devices, such as high-temperature self-destruct devices.

And this telescope, Li Hang also plans to get such a device in it.

All you need to do is break the glass, or even destroy the entire structure.

Anyone can make a bamboo tube, but not everyone can make glass.

All you need to do is get two things in there to destroy the telescope.

What's more, the glass that has just been made is very hard but very brittle. "This thing can probably be made in five days, and you can try it when the time comes, just take a look at the household registration information together!"

Li Hang narrowed his eyes, in addition to this thing, there is actually another thing that he can make, but that kind of thing takes too much time, and it is inconvenient for the time being, but this thing can definitely be shocking enough!
