Princess, he is rich enough to rival the country

"telescope?"

Qin Lu was initially interested because Gu Yanshu said it was a gift for him, but now that he heard the name, Qin Lu became even more curious.

With the magnifying glass on the front, this telescope, literally, seems to be well understood.

But Qin Lu didn't understand, how could a small bamboo tube be able to see far away?

Thinking about it, Qin Lu put the telescope in his hand and weighed it, only to realize that this is not a simple bamboo tube, in the middle of the bamboo tube, there are also several pieces of glass like a magnifying glass inlaid.

Gu Yanshu smiled, pulled Qin Lu to the window, stretched out his hand and opened the window, then turned to look at the person standing behind him:

"My lord, look at the pine tree outside the courtyard from here."

Qin Lu raised his eyes and happened to be able to see a pine tree outside this small courtyard, a little far away.

The pine trees are hardy to cold, even though it has entered the middle of winter, they are still lush and green, especially after the snow fell in the past two days, they are covered with silver, which is very beautiful.

But the pine tree is not a rare plant in Prince Li's residence, so it shouldn't be worth Gu Yanshu asking him to take a special look at it.

Just when Qin Lu wanted to ask Gu Yanshu the meaning of this move, Gu Yanshu had already spoken first:

"My lord is like this now, can you see the pine leaves on the pine tree clearly?"

Hearing this, Qin Lu looked at the pine tree again, and then answered:

"It doesn't look real."

The pages of the pine tree are already slender, and because of the snow in the past two days, a lot of snow has accumulated on the pine leaves at this time.

Even in Qin Lu's eyes, he could reach the point of piercing Yang with a hundred steps, but he still couldn't see the true face of Songye clearly.

Gu Yanshu smiled after hearing Qin Lu's answer, took the telescope from Qin Lu's hand, put it in front of his eyes for a while to adjust it, and then handed it to Qin Lu again:

"My lord, look through the binoculars now—look at the pine leaves?"

Although Qin Lu didn't know how to use the telescope, he could still see the actions Gu Yanshu made when he just adjusted it.

Reaching out to take the binoculars, according to the action of taking care of Yanshu just now, he put it in front of his eyes and looked at the pine tree.

At this time, Qin Lu was surprised to find that not only could he clearly see the pine leaves on the pine tree, but he could even see clearly the accumulations on the pine leaves.

The appearance of snow.

This feeling was as if he and the pine tree were only a short distance away.

If the magnifying glass and glasses just now are useless to Qin Lu, it can even be said to be completely useless.

The telescope's effect on Qin Lu can even be answered with "incalculable".

Qin Lu is a general, after seeing that a telescope can make it easy for people to see objects in the distance.The first reaction is to use this telescope on the battlefield.

You must know that on the battlefield, mastering the enemy's information can be said to be the key to victory.

Therefore, before each battle, scouting the enemy's situation is extremely important—Huan, Tian Qi has also lost countless excellent soldiers because of this.

What if the telescope can see farther than the distance from the window to the pine trees outside the courtyard?

Even if it is only the distance from this courtyard to the gate of Prince Li's Mansion, the survival rate of the leading investigators can be greatly improved!

Thinking of this, Qin Lu couldn't help but couldn't restrain the excitement in his heart, and hurriedly asked:

"I don't know how far the Wangfei's telescope can see clearly?"

"Well... the distance that the telescope can see clearly varies from person to person. Like the one in the hands of the prince, it is a hundred-fold telescope, which can magnify things a hundred times. The distance..."

Gu Yanshu thought for a moment, and decided to give an example directly:

"I heard that the prince's arrows are as good as gods, and he can reach the point of piercing Yang with a hundred steps. I think the prince's eyesight must be extremely good?"

"It's not extraordinary, but it's better than ordinary people." Facing Gu Yanshu's praise, Qin Lu became a little humble.

"The hundred-step piercing Yang is true."

Gu Yanshu knew Qin Lu well, and knew that he would never exaggerate.

Wei Wei nodded, and began to quickly calculate in her heart:

Two steps for an adult is 50 meters, and [-] steps is [-] [-] meters.

The telescope is a hundred times telescope, one hundred times one hundred and fifty meters is one hundred and fifty thousand meters, five hundred meters is one li, and one hundred and fifty thousand meters is thirty li.

After calculating the result, Gu Yanshu spoke directly:

"Take the prince as an example. This binoculars can make the prince look at the target thirty miles away, as if it is only a hundred steps away from it. But the prince also said just now that his eyesight is extraordinary, so ordinary people

In other words, at the farthest, you should only be able to see clearly the archery target ten to fifteen miles away. "

When Gu Yanshu said this, Qin Lu froze on the spot.

Not to mention the thirty miles that Gu Yanshu said, even the ten to fifteen miles in the future have far exceeded Qin Lu's expectations.

You must know that what Qin Lu thought in his mind at the beginning was only the distance from this small courtyard to the gate of Prince Li's Mansion, and this distance is not even a mile!

If he didn't know Gu Yanshu's temperament, Qin Lu would even think that Gu Yanshu was uttering lies.

But even so, Qin Lu couldn't believe it:

"Princess, is this true?"

"Nature is true."

Gu Yanshu smiled, and didn't care about Qin Lu's doubts, and even felt that Qin Lu's expression of wanting to believe but not being able to believe it at this time was rare and cute:

"It's just that the conditions for using this telescope are relatively harsh. It can only be used in places without shelter. If the prince doesn't believe it, why don't you try it outside the city now?"

There are many high mountains in the outskirts of Beijing in Tianqi, and you can see the whole capital city by climbing to the mountainside. This telescope is naturally perfect for trying it out.

Now Qin Lu's mind is full of the "ten miles", "fifteen miles", and "thirty miles" that Gu Yanshu said, how can he sit still when he hears these words?

Dang even turned around and began to order Zhi Ge to harness the horse, so he was going straight out of the city.

Seeing how Qin Lu turned around and walked out the door, Gu Yanshu stopped him dumbfounded:

"Is the prince planning to take me with you?"

To this, Qin Lu gave the answer without even thinking about it:

"It's cold now, going out of the city is another toss..."

Before Qin Lu finished speaking, Gu Yanshu interrupted him:

"My lord doesn't take me with me, so he knows how to use this telescope?"

Now Qin Lu's words were blocked in his throat before he could say them.

At this time, he finally remembered that before handing over the telescope to him, Gu Yanshu had indeed fiddled with the telescope for a while.

Seeing the looseness on Qin Lu's face, Gu Yanshu quickly answered:

"I'll just wear thicker clothes for a while. I've been in the mansion for the past few days, and I'm a little stuffy. I just took this opportunity to go out and get some air."

"But it's getting late now, if you take a carriage, I'm afraid you won't be able to return home before closing the city gate."

Now the time is approaching You time, and the carriage travels slowly in winter, and it takes less than half an hour to get from Prince Li's mansion to the gate of the city, not to mention that it will take more time after the city.

Drive for a while.

The city gates closed a little early in the winter of Tianqi, and they would close at Xu time. That is to say, there was only one hour left now, and it was impossible to catch up.

Although according to Qin Lu's identity, even if the city gate is closed, the guards guarding the city can reopen the gate.

But accustomed to the rigor of the military, Qin Lu didn't like making such special cases.

"Then just ride a horse." Gu Yanshu replied without thinking.

"Can……"

Qin Lu still wanted to say something, but Gu Yanshu had already picked up the cloak beside him and put it on his body. By the way, he also picked up Qin Lu's cloak, and put it on for Qin Lu:

"It's nothing to worry about, it's not like I haven't shared rides with the prince before."

On the day of their wedding, the two were still unfamiliar, and Gu Yanshu was sitting on Qin Lu's horse and came to the palace.

Now the two are familiar with each other, and even the relationship is much closer than before, so naturally they can ride together.

Now Qin Lu had nothing to say, he could only follow Gu Yanshu's actions, and finally took Gu Yanshu with him and went out together.

Although Zhige didn't know why his lord suddenly let him tie up the horse at this time, he didn't hesitate in his movements, and he pulled Qin Lu's horse out after a while.

Then, Zhi Ge saw the concubine brought by his lord - got on the horse together, and then the two of them headed towards the city gate.

Rao is used to the intimacy between his prince and concubine, Zhi Ge is still confused by the sudden action of the two:

Could it be that the prince and concubine have researched some new and inappropriate way?

While thinking this way in his heart, Zhi Ge did not forget to get on his horse and followed directly behind the two of them.

Time was short, after leaving the city, Qin Lu went directly to the nearest mountain forest, and not long after, he brought Gu Yanshu to the middle of the mountain.

After stopping, Qin Lu asked Gu Yanshu in a low voice:

"How does the princess look here?"

"good."

Gu Yanshu nodded slightly.

Although this place is not a commanding height, it can still have a panoramic view of the entire capital city.

Knowing that Qin Lu was impatient, Gu Yanshu took out the telescope without Qin Lu even asking.

Put it in front of your eyes and debug it, then pass it to Qin Lu:

"My lord, you can try it now."

Even here out of town—

During the time on the road, I have calmed down a lot, even though I have already prepared myself.

But when he took over the telescope and really felt the images projected from it, Qin Lu was still shocked.

It's different from looking at the pine trees outside the courtyard from the window in Prince Li's Mansion.

At this time, Qin Lu looked at the capital from the mountainside, and he could better understand the role of this telescope on the battlefield.

This place is at least five miles away from the capital. With such a distance, Qin Lu can only see the frozen layout of the capital without a telescope.

But now, Qin Lu could even clearly see the two city guards talking to each other at the city gate.

You can also see clearly the hawkers yelling in a low voice inside the city gate.

Going further in, you can even see the servants who are sweeping in the homes of some people with shorter courtyard walls.

……

Even if he stopped looking down, Qin Lu could still know that this telescope, as Gu Yanshu said, could allow people to see clearly the situation ten miles away.

If this is the case, won't the soldiers of Tianqi be able to clearly know the direction of the local troops and troops ten miles away in the future?

Thinking of this, even Qin Lu, who had experienced strong winds and waves, and could not change his face even before Mount Tai collapsed, couldn't help but speed up his heartbeat a little.
