Datang: My private money was exposed by Li Shimin

Hearing Fang Xuanling's prompt, Li Shimin felt that it was quite reasonable, and without hesitation, he held the cylinder upright in his hand, and put the larger end in front of his eyes.

but.

When he used this method to look at the items on the table, he found that not only did they not get bigger, but they got farther away.

After a little longer, I feel a little dizzy and my eyes are quite uncomfortable.

"It doesn't seem to have any effect?" Li Shimin frowned, and looked at the cylinder in his hand again.

The glass just now seems to have some effect. Although it is better than nothing, at least I don’t feel uncomfortable. The cylinder seems to have the opposite effect.

Li Shimin's heart sank suddenly...

I thought this was another treasure discovered, but found that it was not the case.

"It shouldn't be..." Fang Xuanling took the weird cylinder and played with it a few times in his hand.

then.

He reversed the direction of the cylinder, put the smaller side in front of his eyes, and in an instant, he discovered the secret in it!
"Your Majesty...Your Majesty!" Fang Xuanling said in surprise while looking at the objects that were too big to be blurred.

"Your Majesty should have held it upside down just now. This is the correct way to use it!"

While saying these words, Fang Xuanling had a whim and pointed the other end of the cylinder to the outside.

He just wanted to try it out. If these items on the table could be enlarged, then everything outside should be able to do the same.

Immediately afterwards...he discovered a new world!
Trees that were originally far away passed through this cylinder, as if they were observing right in front of them.

even.

On the nearest tree, even the thinnest branches can be seen clearly.

This is simply incredible!
If you only rely on your own eyesight, it is absolutely impossible to see that far!
"What did you say?" Li Shimin raised his heart that had just sunk.

Not only him, even Cheng Yaojin limped over, staring curiously at the cylinder in Fang Xuanling's hand.

"Your Majesty, please look!" Fang Xuanling followed the method just now, indicating to Li Shimin the correct way to use it.

as predicted.

The original uncomfortable feeling was gone, replaced by a very clear scenery in the distance, Li Shimin could even see the unknown birds flying among the trees through this cylinder.

This feeling is so subtle!

Li Shimin only felt that no matter how he looked at it, he felt quite fresh.

Not only that.

He also kept using his original vision to distinguish the difference between the two.

The more this happened, the more he discovered the benefits of this mysterious cylinder, which could actually help him see things so far away, and so clearly.

No wonder Li Jianjian studied so carefully, this is such a treasure!

"Let me see..." Cheng Yaojin couldn't bear it anymore, and looked at Li Shimin expectantly.

immediately.

He got his wish to experience the world inside the cylinder!

"It's amazing...it's really amazing!" Cheng Yaojin held the cylinder, and even his voice trembled.

What he thought of was not only that this thing can see so far, but that if this thing is applied to the battlefield, it can play a vital role in observing the enemy's situation.

Just imagine.

If the enemy's whereabouts, or the deployment of troops, has been checked in a place that the enemy has never expected, it will change the situation of the next battle!

"Yes, if all the generals of our army have this thing, it will play a vital role in the future battlefield!" Of course Li Shimin knew what Cheng Yaojin was thinking.

In fact.

After he discovered the actual function of the cylinder, he also thought of its impact on the war.

"Not only that, if Your Majesty takes this thing with you when you are traveling in the mountains and rivers, you can also have a more detailed feeling. The benefits brought by these things are too many!" Fang Xuanling nodded in agreement.

immediately.

He rolled his eyes and looked at Li Shimin with a smile on his face, "Your Majesty, I wonder if these things can be experienced by me?"

The implication of these words was that he wanted Li Shimin to reward him with this mysterious cylinder.

after all.

He had just experienced the marriage, and his request was not too much, so the emperor should have no reason to refuse.

This thing is so wonderful that no one can control the urge to have it.

Who knows.

Before Li Shimin could respond, Cheng Yaojin limped over and held the cylinder in his hand without hesitation.

"The value of this thing is far more than a simple trip to the mountains and rivers. Now this is the only one. Of course, it must be well used in the army!"

"At the very least, let the generals at all levels experience it in advance, so as to lay a solid foundation for the future, so, let me take this thing first!"

"This..." Fang Xuanling wanted to argue, but Cheng Yaojin had a good reason.

not to mention.

Li Shimin has always been very generous to the army, as long as he has what he has, he will definitely give it away without hesitation.

He also had no choice but to suppress the impulse in his heart, thinking about waiting for a suitable opportunity in the future to strive for such clairvoyance for himself.

"By the way, this thing should be mass-produced, right?" Thinking of this, Fang Xuanling turned to look at Wang Xuan seriously and asked.

This is the crux of the problem!

If there is only one in the world, then Cheng Yaojin can't easily take it away.

Li Shimin also turned his head to look at Wang Xuan with great anticipation. What he hopes most is that all generals in the army can have such clairvoyance.

"It should be possible!" Wang Xuan nodded slowly.

"I once heard His Highness mention that once the things in this laboratory are successfully developed, they can be mass-produced in the future. This is also the purpose of His Highness to make these things!"

As soon as these words came out, everyone breathed a sigh of relief.

Their attention quickly fell on the mysterious cylinder again, and they couldn't help feeling emotional.

"Your Highness is truly a god and a man. He was able to research such a wonderful thing. With the combination of two lenses, he was able to reach the level of clairvoyance!" Fang Xuanling said with emotion.

How can you believe these things if you have not experienced them yourself?
"I've said long ago that as long as His Highness makes something, there will be no vulgar things. From now on, there will be good things to watch on the battlefield!" Cheng Yaojin said with a smile and a little complacently.

He seemed to be able to see that in the future on the battlefield, the generals of the Tang Dynasty knew everything, but the enemy was always kept in the dark and played around.

Li Shimin focused on other things. Since this is Li Jian's laboratory, it is definitely not just such a good thing as clairvoyance...
