I heard Li Liang say that the station of the Shence Army camp is in the West Mountain, and it is too far away to see clearly. Wei Renshi's mind became lively.

If we want the method of military training to be finally affirmed, it must still be reflected in the enhancement of combat effectiveness.

Whether it is the command or the combat ability of the soldiers, it is all an improvement in combat effectiveness.

And at the moment, the best way to show the improvement of the combat effectiveness of these 1,100 soldiers is to let them fight with the army with the strongest combat effectiveness at the moment.

But the Divine Army is the Divine Army after all, and it is not so easy to deal with. Wei Renshi didn't really expect that the 1,100 people who had only been trained for half a year would be able to defeat the same number of Shence troops at this time.

However, if you can observe the ordinary training methods and habits of the Shence Army and formulate corresponding measures, you can at least fight a beautiful battle, and the loss will not be too bad, and even let the Shence Army win a miserable victory.

There is still a need to go and see the camp of the Shence Army.

Wei Renshi pondered for a while, then looked up at Li Liang and asked, "Brother Li, you said that we went to peek at the Shence Army camp, if we were discovered, how would we be held accountable?" ”

"Brother Renshi, could it be that you ......" Li Liang said in surprise: "Are you going to peek at the drills of the Shence soldiers?" ”

Wei Renshi nodded and said, "Yes, as you just said, knowing yourself and knowing your opponent will not be defeated in a hundred battles." These soldiers are too far behind the soldiers of the Divine Strategy, and they cannot catch up with them in just half a year. If you want them to fight more beautifully when the time comes, you must prepare for the habits and characteristics of the Shence Army's combat. Since we don't have a way to get in, we can only peek outside. ”

Li Liang scratched his head and said, "Brother Renshi, not to mention that we were caught peeking at the Shence Army camp, even if we were not discovered, we couldn't see it!" There is not only a wall outside the Shence Army, but also patrolling soldiers, if we can get in, we will definitely be discovered. If you want to stay out of the way, you have to stay outside of their patrol route, and you won't be able to see anything. ”

"What if I had a way?" Wei Renshi said: "Brother Li, just tell me, if we are discovered, how will we be dealt with?" ”

"This ...... It is a great crime for ordinary people to peek at military drills. Li Liang thought for a while and said, "However, in terms of a few of us, we shouldn't be punished too heavily, but a board must be indispensable after all." ”

"That'...... Is there a way not to be discovered? Wei Renshi asked again.

"This ......" Li Liang thought for a while and said, "If you want to be sure not to be discovered, unless you go up to the top of the West Mountain and look down." But it was so far away—I couldn't even see the camp layout, let alone see their soldiers drilling! You can't see the people inside at all. ”

"How far?" Wei Renshi asked: "From the top of the West Mountain, when I saw the inside of the Shence Army camp, how far did I estimate it to be if I looked straight at it?" ”

"This ......" Li Liang shook his head and said, "If you look directly, you have to have eight hundred steps!" ”

Wei Renshi nodded thoughtfully, touched his chin and said, "Eight hundred steps...... You can give it a try! ”

"Try what?!" Li Liang asked.

"Brother Li, do you want to try the feeling of clairvoyance?" Wei Renshi asked.

Li Liang was stunned: "Clairvoyance? ”

Wei Renshi nodded, shook his head again, and said, "It's an exaggeration to say that a thousand miles are an exaggeration, but a thousand steps is not impossible, what's the matter?" ”

Li Liang looked at Wei Renshi in a daze, thought about it, and suddenly said in shock: "Spell?!" ”

"It's not. It's about making something that allows people to see far away. Wei Renshi said: "If I make this kind of thing, let's take it up to the top of the West Mountain and secretly take a look at the camp of the Shence Army, do you dare?" ”

"Can people see far away?" Li Liang was even more confused, paused, and said: "If I can really make something that can see so far away, then I must take a look, why don't you dare?" At that time, let's say that we think that these thousand people are not bad, and I want to see if it is similar to the Shence Army, and there is no way to enter the Shence Army, so I secretly take a look, which can be regarded as a reason, at most two hundred battles! ”

Wei Renshi grinned and said: "Brother Li, this is a good reason, well, in my opinion, let's bring Prince Chun and Fan Zhiyi with them, and when the time comes, the law will not blame the public, and we will be able to excuse it." ”

As he spoke, he squeezed his eyes and smiled at Li Liang.

"Not bad!" Li Liang immediately grinned, and his back molars were exposed.

What Wei Renshi thought of was a telescope.

Keplerian telescopes, to be exact. The telescope consists of three parts, consisting of two convex lenses and a prism in the middle as an orthographic system.

Nowadays, glass can be fired in glass kilns, and it should not be difficult for the person who blows the liquid glass to blow it into convex lenses and prisms.

This craft was learned from the parents of the students in later generations. In a handicraft class, the parents of a student who worked in a glass factory didn't know what to think, so he made a single tube out of a cardboard tube for his son, and when he got to the school, he knew that it was not made by the students themselves.

Later, when I had a parent-teacher conference, I saw the parent mention it, Wei Renshi thought it was very interesting, so he chatted for a long time, and then realized that it was very simple.

But in the end, it was made by hand, and Wei Renshi was a little worried about whether he could see that far.

The distance that this telescope can see is related to the thickness of the lens. The thicker the lenses used – that is, the convex lenses that are placed – the thicker the middle, the farther you can see, and the thinner the middle, the closer you can see. A prism positive image is also needed between the two convex lenses, otherwise the picture seen is upside down.

In addition, the length of the eyepiece of the convex lens is calculated.

Wei Renshi thought about it and felt that it was too complicated to do, but it should still be possible to make a simple monocular.

At the end of the day's training, and for a short period of time when the soldiers were free to move around after dinner, Wei Renshi sent someone to bring Li Chun, Fan Zhiyi and others to the big tent.

As soon as he entered the big tent and saw that there was no one else inside, Fan Zhiyi sat down with a look of lovelessness, and said to Wei Renshi: "Brother Renshi, how did you come up with this method of military training?" It's also so tiring! It's just torturous! ”

Everyone also complained, although Li Chun did not speak, but his face was full of "I have a relationship with my heart", and he also betrayed his ideas.

"Sweat more in peacetime and bleed less in wartime." Wei Renshi said: "If you want to become an elite soldier and become a master of all victories, how can it be as simple as just talking. No pain, no gain. ”

Everyone actually understands the reason, but they just talk about it. Hearing Wei Renshi say this, he stopped complaining.

"Brother Renshi, didn't you say that except for Prince Chun, we must not reveal our identities, why did you call us in the first day?" Zhang Zhongwu asked.

"There's something I want to discuss with you." Wei Renshi said: "A few of us are now in the same boat. ”

"Oh? What's the matter? The crowd asked curiously.

"I'm going to make something that allows us to see a scene far away, and then let's take this thing to secretly see how the soldiers in the Shence Army camp practice, and then formulate a combat method for them, and when the half-year period arrives, let 1,100 people from the Shence Army fight with us!" What's the matter, do you dare to go?! ”

A few gentlemen have always been the masters who don't think it's a big deal to see the excitement, and they are afraid that the world will not be chaotic, and when they heard Wei Ren's real excitement, they immediately shouted why they didn't dare to come, and they agreed one after another.

Only Li Chun asked curiously, "Something that can see a scene far away?" What's that? ”
