Usually, the two of them washed up together, so they would not be delayed for half a day.

Today, with a new love, Feng Jing took a battle bath.

Don't even rub your back.

Don't press Su Huan's shoulders anymore.

Humph, she is not missing her.

After washing up, Su Huan changed into a black training suit and rode his horse under the gate of the border city.

But it was not the gate where Su Hua entered the city, but the gate leading to Beixia.

Seeing Feng Jing's arrival, the soldiers were all respectful.

The news that the princess came to the border town had already spread throughout the border town, so when she saw Su Huan dressed as a man, the soldiers had already guessed her identity.

He was very polite to her.

Su Huan climbed up the city wall with Feng Jing who was so excited that he was like a child, "Look at you're happy."

"Of course I'm happy. I don't know how far this thing can be seen." Just now, I could only see the walls at home at the farthest. Looking towards the sky, I couldn't see anything in the sky.

How can you see a modern telescope? How can you see a farther picture than what Ye Siyin has troubled in ancient times?

Su Huan just thought so in her heart. She was a poor student and didn't quite understand the principle of telescope multiples.

However, there are many telescopes of different magnitudes in her space, as well as astronomical telescopes. No telescope should be as far as the astronomical telescope.

Ahem, if you say it wrong, no one will come to scold her anyway, hehe.

But the one I gave to Feng Jing now is more retro. If I really take a military telescope, wouldn’t it be confirmed that Ye Siyin guessed that she had room?

She can't hand over such a trump card now.

This kind of simple telescope is a time traveler who knows a little bit. Although he may not be able to do it, Su Hua can also use the excuse that he can make a telescope. Moreover, Ye Siyin has made the glass, so she used Ye Siyin's glass to make the telescope.

This statement also makes sense.

"Huh." Su Hua looked out of the city wall.

"What's wrong?" Feng Jing looked at Su Huan sideways, so he didn't see anything outside the city wall.

"I just saw the reflection. Someone must be secretly looking at us. I point in one direction, you look over there." Su Hua quietly pointed to a direction and angle. Feng Jing immediately understood. After pulling out the telescope, he immediately put it in front of him and looked over there.

"I saw that the man also had something the same as the tube in my hand." Feng Jing did not dare to look at it for a long time and put down the telescope.

He didn't even watch it for a long time. Su Hua asked worriedly, "Did they find you?"

"No, they just put down the copper tube in their hands and were talking." Feng Jing was not planning to expose that he had this thing for the time being, "Will they see that there is a reflection on me?"

The telescope that Su Huan gave to Feng Jing seemed to reflect, not a military honeycomb lens with anti-reflection settings.

Although there is in the space, it is not enough to take it out now.

"When you use it in the future, avoid using it directly under the light source, hide in the shade, and it should not reflect light. Only when there is light reflection will it reflect light. Without light, what light will it reflect."

Ye Siyin probably doesn't want to be found using a telescope. In places like Mobei, there are even a few trees outside the city walls. Those people have to use telescopes to observe the situation in the city from time to time, and it is difficult to find a shaded place to hide.

Feng Jing had a strong learning ability and felt that Su Hua's words made some sense. He walked to the lookout room on the city wall, stepped back and left, found the angle, and then continued to take out the telescope to use it.

"Can you see so far." Feng Jing estimated in his mind that he could see so clearly that he could see so far. He could see the faces of those people clearly. This thing was really a surprise.

"Is this designed by Ye Siyin?" He put down the telescope again, feeling uneasy. "She used to make a lot of things. Such a copper tube could see so far, which is really in line with the name of clairvoyance. It can be used in military affairs to make people suffer from everything. I don't know if she will make anything else."

"This thing was not invented by her." As a modern person, Su Hua was very confident in denying it. She used to be the most disliked by some copywriting articles in time travel novels. The inventors said that other people's credit was their own, but some situations are understandable, such as the situation where they can't even eat.

If you just want to show off, it is really unnecessary.

It would be great if she was not as educated as she was. Otherwise, she would have taken out three hundred Tang poems and Song lyrics from the space and could easily create a great literary character.

"How do you know, my wife?"

"Do you still remember someone? We wanted to build a house in the village. I went to find someone who designed the house. He told me that someone was looking for him, just to grab things from him, so I think..." Speaking of this, Su Huan looked at Feng Jing with a little difficulty in writing, hoping that smart people could have a complete brain.

Although it was a relatively long time ago, Feng Jing still had some impressions, "I remembered that when I checked Ye Siyin's rebellion, I found that she had secretly summoned many skilled craftsmen, including the one you were looking for, and hid in the countryside in order to avoid her. Unexpectedly, she still couldn't escape her persecution."

"I understand that Ye Siyin's clever ideas should be the ones that snatched from the hands of those craftsmen."

No, telescopes are not, but I can’t explain anything else clearly.

"Qian Qin has never paid attention to these strange and lewd skills. It seems that I will still have to tell my brother in the future, and I will pay more attention to the Ministry of Works."

That's not, only countries that focus on scientific research and development have a future. If they don't develop new technologies, they will sooner or later be crushed by other countries' technologies.

Although the development of technology may not necessarily bring benefits, technology itself is not bad. It is just that some people use it to do bad things.

Just like Ye Siyin used modern knowledge to do bad things in ancient times, she knew how to cure smallpox, but she deliberately spread it just to make herself a savior.

These time travelers are intruders themselves, and they have made contributions to their own lives in a corner. Those who use the knowledge of future generations to benefit the people are more respected, but don’t do bad things.

Su Huan even suspected that he had traveled here, afraid that God had brought her over to suppress Ye Siyin?

"Madam, what are you thinking?" Feng Jing thought Su Hua was scared, so he held her in his arms and comforted him, "Don't worry, no matter what Ye Siyin can make, I will protect the border town."

Ye Siyin can make more things. There are fireworks and firecrackers on its own, so it is easier for her to transform them into more powerful weapons.

Su Huan hugged his upright and powerful waist tightly, "I'll accompany you."
