"Stop talking nonsense, get it and show it to me!"

Brother Zheng said impatiently.

He really wanted to look at this so-called "artifact".

After Ying Changsheng heard this, he hurriedly ordered someone to take the telescope he came out of.

Win the telescope of immortality.

is a relatively primitive one.

Monoculars.

The principle of this telescope is actually very simple.

It's just a few lenses.

Of course, this lens is not easy to make.

It takes craftsmen to find a way to polish it.

Moreover, after sanding, there must be no scratches on it.

Otherwise, the clarity will be affected.

Most importantly.

The cost is also relatively high.

Because, in these years, Ying Changsheng has not invented such a thing as glass.

Therefore, you can only use that precious crystal to make lenses.

Therefore, the cost of a telescope is not low.

Want to use telescopes in large quantities like the future generations?

It can only be a dream.

However, after making hundreds of binoculars and handing them over to his soldiers for reconnaissance, Daqin was still able to do it.

Because, the price of crystal, is not expensive.

Transparent crystals are hard to find.

But it's not that you can't find it.

And, most importantly.

A telescope.

There are actually not many crystals needed.

That is, just a few crystals.

Not much.

With the return of the people sent out by Ying Changsheng.

I saw that this person was holding a small box in his hand.

Brother Zheng looked at the box in surprise.

I saw that Ying Changsheng stretched out his hand and opened the box.

What was revealed was a monoculars made of brass inside.

The technical content of binoculars is much higher than that of monoculars.

Therefore, for the time being, Win Changsheng did not overcome this difficulty, but only saw that he took out the binoculars, and then, Brother Chaozheng said.

"Father, let's go outside and try this thing!"

"Good!"

Brother Zheng shook his head again and again.

Immediately, with Ying Changsheng, he walked out of Zhangtai Palace, the palace of the Qin and Han dynasties.

Like to build the earth, and then build the palace high.

In this way, the kings can be condescended and look down on the ministers, or they can climb high and look into the distance, and then let the courtiers of the four directions be shocked by the high palace, so that the ministers can be used under the feet of the king.

At this moment, standing outside Zhangtai Palace, Ying Changsheng first took the telescope and looked around a few times, and found that the telescope was not bad.

As if offering a treasure, he sent the telescope to Brother Zheng.

Brother Chao Zheng explained.

"Father, close your left eye, then aim it with your right eye, and then look into the distance!"

"By the way, I'll see it later, it may be a little shocking, be careful, don't, don't be scared!"

Well, first-time binoculars.

It's inevitable that you'll be shocked.

After all, suddenly.

When a distant sight or person appears in front of you, it's hard not to be shocked.

After listening to Ying Changsheng's explanation on the side.

Brother Zheng also carefully held the binoculars, and then looked into the distance.

I only glanced at it, and when I saw clearly that the guards who were standing guard not far away, they were talking to the guards next to them.

Brother Zheng immediately put down the telescope.

Then, exclaimed.

"This thing is really amazing!"

"Father, this thing is very powerful, but in fact, the principle is very simple!"

Worried about Brother Zheng, he regarded this telescope as some kind of artifact.

Then, feudal superstitions were born.

Therefore, Ying Changsheng hurriedly explained the principle of the telescope to Brother Zheng, only to hear him open his mouth and say.

"The principle of this telescope is actually very simple, nothing more than two lenses, magnifying the distant scene, and then presenting it in front of people!"

"If you drop water on a flat surface, you can see that the words on the plane, or small things, will become larger, has my father ever discovered this principle?"

"Oh?"

When Ying Zheng heard this, he immediately bowed his head and said.

"I, I've met it!"

"Erchen, it's the crystal that is ground into such a shape, and then the ......"

Brother Win Changsheng said.

"This is Erchen, I found it by accident!"

"Now, with this, I can increase the range of vision several times, with this thing, with the hot air balloon, you can reconnoiter the scene within a radius of dozens of miles, at that time, my Daqin will be able to, in advance, the movement of the army under the command of King Donghu, and then, get ready, transfer troops, so, it is difficult for King Donghu to be undefeated!"

"Moreover, General Wang Jian once proposed a tactic, that is, to use a hot air balloon, loaded with bombs, to fly to the enemy's head and drop bombs!"

"Now, we can also use this method to deal with the Donghu people who are coming!"

"That's a good idea!"

When Win Zheng heard this, his eyes suddenly lit up.

Immediately, he slapped his thigh and said.

Indeed, this method is simply not too good.

It's completely possible, it's easy, to defeat the Donghu people.

Saying that, Brother Zheng, he couldn't put it down and took the binoculars and looked into the distance.

Then, I saw him sigh with emotion and mutter.

"This thing is really amazing!"

Saying that, Brother Zheng seemed to think of something, he suddenly opened his mouth, and then asked Ying Changsheng on the side.

"Changsheng, have you ever named this thing?"

"This, this has never been ......"

Hearing this, Ying Changsheng shook his head.

I plan to give this opportunity to give my name to Brother Zheng.

And Brother Zheng, after hearing this, he smiled slightly, and then, after pondering for a while, he opened his mouth and said.

"I have a name for this thing, I think it's quite appropriate, so I just call this thing a clairvoyant!"

"Your Majesty, that's a good name!"

When Wu Shilu next to him heard this, he hurriedly sent a sycophant.

"The clairvoyant mirror, it sounds good, and it is exactly what this clairvoyant mirror means!"

Listening to Wu Shilu's compliments, Ying Zheng looked at Ying Changsheng and asked.

"Changsheng, you kid think, is this name okay?"

"Father, this name, of course it's okay!"

Ying Changsheng first said with a smile to Brother Zheng.

Immediately, his words changed suddenly, and then he said to Brother Zheng.

"However, father, this clairvoyant mirror is here, and the hot air balloon is also available, is it okay to let the sons and daughters lead the troops to deal with the Donghu people?"

"This ......"

When Brother Zheng heard this, he couldn't help but remember that he had just said it.

If, there is really a way to win Changsheng.

Let him lead his troops to deal with the Donghu people.

Thinking of this, Brother Zheng realized that he couldn't break his word, so he gritted his teeth and said to Ying Changsheng.

"I promise you to lead troops to guard the Great Wall and deal with the Donghu people!"
