Du Jing followed Qian Zhihong to his room in the Yamen of the Ministry of Industry.

"Qian Shangshu, thank you so much today. ”

Qian Zhihong waved his hand again and again and said: "Du Zhutou, don't say that, Quanbai's parents are civilians, and I have no way to discipline them on weekdays, and I have doted on them since I was a child...... Forget it, it's over. ”

As he spoke, after Qian Zhihong invited Du Jing to sit down, he greeted him with tea and politeness, which made Du Jing a little overwhelmed.

If you want to say that this money is grand and selfless, it will not be like this.

If Qian Zhihong is grateful to himself for solving the theft of the earth-level magic weapon, there is no need to put his nephew in it.

Then there is only one possibility, that is, this Qian Zhihong is showing loyalty to the emperor.

When he first went to the palace to force the palace, Qian Zhihong did not go to the palace, and when he talked to Du Jing later, he also said that he longed for the legal society depicted by Du Jing, because this could make the efficiency of his Ministry of Industry better.

It seems that most of this is because of this.

In fact, Du Jing really thinks too much, and Qian Zhihong admires Du Jing completely from the heart.

Especially in the past two days, with the manufacture of the camera, he has become more and more thorough in understanding the formation rules in the drawing of the camera, and he admires Du Jinglai even more in his heart.

Now Du Jing is just not strong, once his strength reaches the cultivation level of the Dan cultivation period, with his current understanding of the formation, as long as the master has a little bit of allocation, he will become a generation of refining masters!

Qian Zhihong had already planned the route for Du Jing, but he didn't tell Du Jing at all, he even felt that Du Jing couldn't wait to apprentice whenever he heard of his master's prestige.

But I don't want this Du Jing to be not even interested in royal exercises and martial arts, so how can he be interested in refining weapons?

"Qian Shangshu, aren't you looking for something with me?" Du Jing coughed lightly, interrupting Qian Zhihong's divergent thinking.

Qian Zhihong came back to his senses at this time, and hurriedly said: "Du Zhutou, forget it, I'll call you Brother Du." ”

You say. ”

I saw that he was embarrassed to take out a piece of paper from the table next to him, which was full of decomposition of formations.

Although Du Jing didn't know this, he knew what went out of him at a glance.

This is exactly the detailed breakdown of the camera formation drawings.

When he handed over the manufacturing drawings of the camera to Qin Lanyu before, Du Jing only told them that they didn't need to understand it and just follow it step by step.

After all, this is the result of modern technology products changing the form, and they may really need to use some brains to understand it.

But because it is a system output, Du Jing knows everything in the drawings well, including the steps that Qian Zhihong has broken down.

"Brother Du, I really don't understand this drawing, I really don't understand this step, what are the rules in it, can you explain it in detail? I really have never seen anything like it before. ”

Of course, Du Jing knew what this part of the formation Qian Zhihong was referring to, which could only be understood by the foreshadowing of physical knowledge.

If you only look at the knowledge of this world, they can't understand the junior high school physics knowledge of Xiaokong Imaging at all.

It's really because Qian Zhihong came out to save himself, and asked himself for advice with such respect, otherwise he really didn't bother to tell Qian Zhihong about these physics knowledge in junior and senior high school.

"Can you understand this part?" Du Jing ignored the part that Qian Zhihong was referring to.

Because that formation uses aura to simulate charge coupling as a photosensitive material, it is a bit too profound to tell him about this now.

Therefore, Du Jing plans to start with the most basic optical knowledge.

Qian Zhihong looked at the front place that Du Jing pointed to, shook his head, and said, "Although I don't understand that place, there is no aura formation, so I haven't been involved in that place for the time being, is it important here?"

Du Jing nodded and said: "That's right, this is the core part of the camera! Without these lenses and polished crystals, it is basically impossible to imprint, and we can only do the initial stage of perception according to color blocks like in the steam robot." ”

Qian Zhihong nodded, but his heart was full of disdain, in his opinion, the most difficult thing in the world was nothing more than the formation he didn't understand, and the lens composed of several crystals without the formation really didn't have anything worth studying in his opinion.

But after Du Jing slowly explained the elementary optical knowledge, his eyes widened and he exclaimed incredibly: "How is this possible? How can it be reversed, I feel that it is all right!"

It seemed that he still didn't believe it, so he shouted loudly: "Qin Lanyu, Qin Shilang, polish a few crystals, come over, make them bigger!"

Du Jing smiled and said, "Don't you believe it?"

Qian Zhihong nodded and said, "I don't believe it, but I don't believe what you said, I still want to see it with my own eyes." ”

I have to say that the speed of the monk polishing the crystal is absolutely faster than that of ordinary angle grinders, and there is no need for low mesh leveling, medium mesh grinding, high mesh polishing, and direct aura highlight polishing A crystal crystal on one side appears.

A few pieces of water crystals were placed in front of Qian Zhihong, and Du Jing directly took out a few small experiments placed by the junior high school physics teacher, which immediately made Qian Zhihong happy.

After playing until nightfall, Qian Zhihong sighed, "I didn't expect this natural world to be so magical, and you can do things that many people can't achieve without relying on the formation aura!"

Du Jing nodded and said: "These are just some of the most basic knowledge of camera imaging, if you move at this point, the other formations will be touched all over the field." ”

Qian Zhihong nodded and said: "This is true, it turns out that the formation that I can't understand is actually used as a photosensitive material, which is really taught." ”

After finishing speaking, Du Jing looked at the sky, and said before it was too early: "Qian Shangshu, it's not early today, I'll go back first." ”

"Okay, okay!" Qian Zhihong reluctantly put down a telescope he had just made, stood up and said, "I'll send you there." ”

The two followed out of the yamen of the Ministry of Industry, and Du Jing repeatedly shirked and said: "Qian Shangshu, please go back, you don't need to send it." ”

"No, I'll have to send it again. Qian Zhihong scratched his head, he always felt that he had something to say to Du Jing, but he had absorbed too much new knowledge in one afternoon, so that he had forgotten what that matter was.

But the more he couldn't remember, the more anxious he became.

"Qian Shangshu, are you embarrassed to say something?" Du Jing stood at the door of the Inspection Division and teased: "You have sent me home, why don't I send you back?"

Qian Zhihong smiled awkwardly, "It's not that I'm embarrassed to say it, it's that I can't remember it suddenly." Forget it, I'll look for you tomorrow when I think about it. ”
