The reason why the people in the Manufacturing Department of the Ministry of Industry suspected that the people from the Xuanqi Sect's Weapons Department had stolen it was because they felt that the drawings used for mass manufacturing could only be used for mass manufacturing, and secondly, they felt that only the people from the Weapons Department could make such things.

Master Yin, who could study the formation transcription, said: "I don't think the Weapons Division is capable of doing this, and you don't know the style of their Xuanqi Sect, where are they the people who do this kind of thing! Not to mention that the formation drawings lost this time are all basic drawings." ”

Qin Lanyu nodded: "But at present, I can only suspect that it is in the head of the Weapons Division, and I really can't think of others." ”

"Isn't it the Mo family of the Mountain Alliance who did it? Aren't they also good at studying the secret weapons and obscene techniques of the organs?" Master Zhuang said his opinion.

But Master Luo and Master Yin retorted at the same time: "How can that group of people in the Mountain Alliance who are not in the stream have such a means!"

Listening to the analysis of these professionals, Du Jing knew at least two suspected targets with the ability to commit crimes, one was the Mo family of the Mountain Alliance, and the other was the weapons department of the Xuanqi Sect.

However, for each of the suspected targets, the reasons are not so sufficient.

The Xuanqi Sect's Weapons Division is an organization that the craftsmen present generally believe have the ability to create robots, they have the ability to commit crimes, but they do not have the motive to commit crimes.

First, because the Xuanqi Sect has always disliked the theft of chickens and dogs, and if you like something, you will either buy it directly with a lot of money, or you will directly rob it, and you will not choose to steal at all.

And the Mo family of the Mountain Alliance, this is a Jianghu sect, they have the motive to commit the crime, but the craftsmen and masters of the Ministry of Industry look down on these unpopular guys at all, thinking that they simply don't have the ability to make this kind of machinery.

In any case, both organizations will need to investigate.

"Okay, let's not talk about this for now, let's hear what Master Du thinks!"

Master Luo said repeatedly: "Yes, yes, Master Du is very good at this, I think he must have a way." ”

How did he become a master? Du Jing couldn't help but be happy, but he thought that maybe this was an honorific title among craftsmen, and he had to respect other people's industry habits.

So he waved his hand again and again and said: "Don't dare to be, don't dare to be." In fact, I was still a little confused before I came, but after listening to the speculations of the masters, I feel that the general direction is still there, in fact, my plan is very simple, that is, let them steal it again!"

"Steal again?" Master Luo asked with some suspicion.

But he didn't want Qin Lanyu to slap his thigh and shouted: "You mean that we are squatting next to us, and then if the other party steals again, we will follow the other party until the other party connects!"

Du Jing nodded and said: "I initially thought so, but after the other party failed once, he has become a frightened bird, and it should not be possible to steal it again in a short time."

So you have to release *** and deliberately create an empty door to lure the other party to steal. ”

“***？”

The four people present were a little puzzled, they really hadn't heard of this ***.

Du Jing then told the plan he had planned, and several people applauded.

"Good way! As long as that guy comes to steal, we promise that he will never return!"

"No, let's let them let their guard down, once the vigilance of the robot is triggered, we are likely to be busy again! After all, it is the machine that steals, not the real person, and we want him to steal it!"

Du Jing's words made everyone a little confused, can you still catch someone if you steal it?

Even Qin Lanyu was a little suspicious, although this Du Jing said that he had some means to solve the case, but this time it was not a person who stole things, and his methods seemed to be completely useless, so didn't he lure the wolf into the house.

However, you can put a fake drawing, and you won't be so distressed if you lose it.

This topic came to an end for the time being, and several craftsmen didn't seem to be interested in solving the case, but instead pulled Du Jing and kept asking questions about the drawings of the camera and the robot.

Although the drawings of the camera are produced by the system, they still have a copy in Du Jing's mind, and he also has a far beyond ordinary people's understanding of this drawing, which comes from the system's contributions.

After a while of explanation, several masters even threw themselves on the five bodies that Du Jing admired.

"Master Du, if you don't come to our Ministry of Engineering, you are really talented, and if you can draw such a precise drawing by hand, I am afraid that the entire Ministry of Industry will have the ability of Master Shangshu. ”

Facing the praise of several craftsmen, Du Jing smiled and waved his hand, and then asked: "The problems have been explained clearly, I don't know how much the camera has been completed?"

Qin Lanyu casually took out a camera that had just been manufactured and handed it to Du Jing, saying: "Actually, what everyone asked just now are some of their own thoughts and questions, there will be no problems at all in manufacturing according to the drawing process, we have completed more than 100 of them." ”

Taking over the camera bolt, Du Jing looked at it carefully, the appearance of this camera is still a little different from the common cameras in later generations, and its principle is also a little different, but it is nothing more than using the principle of small hole imaging to record the imaging picture with aura.

After playing carefully, Du Jing said: "I'll take away these more than 100 cameras first." In addition, I would like to ask Master Yin a question about the robot. ”

Master Yin was a little surprised, whether it was the formation of the robot or the camera, Du Jing's understanding was far above them, why did he still ask himself?

"Master Du, what you said really hurt me, what you said is that let's discuss it together. ”

"How far can the robot's data transmission array transmit?"

The data transmission formation that Du Jing said was a formation that Master Yin had asked Du Jing about just now, which he had never seen before, this formation was transformed on the basis of the transmission note, but it was not only to transmit sound, but also to remotely control the robot.

This is also the most mysterious place of the steam robot, just now when Master Yin consulted Du Jing, Du Jing named it the data transmission array.

The basic physical knowledge of this world is still in the hands of a very small number of people, for example, this transmission note is nothing more than using the principle of sound generation to vibrate, record this vibration, and then through point-to-point spiritual power transmission, when it reaches another transmission note, this vibration is restored through spiritual power, which also forms an ultra-long-distance transmission of sound.

According to Du Jing's guess, the data transmission array also generates different signals through vibrations of different frequencies, and then restores the signal through the differential machine in the robot's body for remote control of the robot.

Both use vibration, one only understands that sound is produced by vibration, and the other understands that vibrations of different frequencies can produce different signals.

This is a qualitative leap.

Even Du Jing once thought that it was done by another traverser, not some weapon or Mo family trick.

"About five miles, there are too many things he wants to transmit, and the frequency is too miscellaneous, so the distance becomes very close, normally, if we transmit the note only through spiritual power and restore the vibration of the sound through spiritual power, the farthest transmission distance can reach about 100 miles. ”

Five miles, that is, 2.5 kilometers.

It seems that the man can only operate near the Yamen of the Ministry of Works, and even cross two or three streets at most.

That's easy to do.
