After Qian Shangshu saw Du Jing, his eyes narrowed with a smile, and he introduced to the monks beside him: "This is Du Jing who solved this case, Du Zhutou!"

Du Jing smiled and arched his hand at the monks, and then pulled Qian Shangshu and said, "Qian Shangshu, I want to find you for something." ”

"This time the stagnant sundial can be recovered, and the old man should thank you very much. Qian Zhihong actually thought about it for a long time last night and didn't come up with what to give to this Du Jing to encourage.

Give a magic weapon of defense? A magic weapon of attack?

It seems that he doesn't need it, this guy's back to the royal treasure is not inferior to his own collection.

Especially the defensive magic weapon that can resist Wang Fang's full force blow, it is a full force blow in the Dan cultivation period, and there is not even the slightest damage!

The magic weapon that can trigger thunder and lightning is even more powerful, it is actually a magic weapon that can be activated by the martial arts realm, and the value of this kind of thing cannot even be easily estimated by himself.

It seems that he can only take this guy to the warehouse of his own Ministry of Industry and let him choose by himself.

"Let's go, let's say in the yamen, aren't you going to get married soon, pick a few by yourself and treat them as my wedding gifts for you." ”

The two of them followed the Yamen of the Ministry of Industry, Du Jing naturally wanted to be polite, he smiled: "Qian Shangshu, you are so polite, forget about the things, I just want to find you to order a batch of things." ”

"Oh, custom-made things, no problem, you wait to find Qin Shilang for this matter, and the things that should be given to you are indispensable!"

After some shirk, Du Jing came to a warehouse in the Ministry of Industry, and the magic weapon here was only a Xuan-level magic weapon at most, but Rao was also very attractive to Du Jing.

However, he had not yet reached the Zhou Tian Realm, and he could not drive his spiritual power, so he could not feel the subtleties of these magic weapons.

After some research, Du Jing really felt that these things were not as good as the police weapons that the system gave him.

Although his police weapons can't use spiritual power to drive the magic weapons, they are not much stronger than these magic weapons.

He randomly selected a Xuan-level immortal sword, this thing looks extremely ordinary in the warehouse, Du Jing just meant to choose it at random, and used it for future sword flight, after all, it is not good to use other magic weapons to fly in the sky.

After choosing the magic weapon, Du Jing hurriedly ran to the manufacturing department to find Qin Lanyu.

At this time, Qin Lanyu was studying the "corpse" of the Xiangling monk who was full of gear machinery, but now it was no longer a complete corpse, but had been dismantled in eight pieces.

Piled all over the floor are geared transmissions and metal orifice plates that serve as operating systems.

Qin Lanyu squatted on the ground at a loss and looked at these gear machines, he really didn't understand, how did this thing move.

Seeing Du Jing walking to his side, Qin Lanyu only nodded slightly, and then continued to study these gear transmissions.

"How does this thing move?" he muttered to himself, as if he noticed that Du Jing was also looking at these things, looking very interested, and he couldn't help but be surprised in his heart, "What's the matter, Du Zhutou also understands these mechanical things?"

"I understand a little bit. ”

Qin Lanyu couldn't help but sneer in his heart, this guy's tone is really not small, such a delicate machine can't figure out the source of its power, what does he know about a head catcher who solves a case.

"Then please ask Du Zhutou to explain a thing or two to me. Saying this, Qin Lanyu did not have a sincere attitude of seeking advice, but was a little disdainful and ready to refute Du Jing's mistakes at any time.

"Through this!" Du Jing pointed to the spherical object that he had dismantled to the side, unscrewed the pressure relief valve and said: "There is a high-pressure aura in this, through the differential machine, well, it is the bunch of gears in the brain that command to relieve pressure, and the pressure relief generates power." ”

Du Jing's explanation still made Qin Lan Yu Yunshan foggy, but he still understood a little, and he couldn't help but be surprised.

Does this guy really understand? Or has he seen something like it before?

"Could it be that Du Zhutou has seen this thing before?"

"I haven't seen it, it's just my intuition, and I feel that this is the only way to do it. ”

Qin Lanyu tried to twist the pressure relief valve that Du Jing said, and a white aura spewed out, and this impetus was surprisingly amazing, and it directly pushed him back a few steps.

It's really as Du Jing said!

The power really erupted from this ball, this power is simply amazing, and he hasn't unscrewed all the valves, if he releases them all, I'm afraid this power will really have the full force of the Qi Gathering Period monk.

Qin Lanyu didn't dare to underestimate Du Jing anymore, and couldn't help but admire it, but he didn't expect that he not only had an amazing talent in solving cases, but also had unique insights in these machines.

He is the first craftsman in the Ministry of Industry, and he is not as good as a head catcher in his professional field, and a sense of frustration arises spontaneously.

"Du Zhutou, where do you think this thing came from? This is obviously not something from the Maoshan faction of the Mountain Alliance!"

Du Jing nodded and said, "I don't think it's something from the Maoshan faction, and I can't say where it comes from." ”

As if remembering something, Du Jing asked, "Qin Shilang, have you ever done any research on the kettle you bought yesterday?"

As soon as he mentioned the kettle, Qin Lanyu was about to regret it, "I bought your thing at a loss, there is no magic circle in it, that is, the material is extremely special, maybe the material comes with storage space, and there is no value in research and learning." ”

It seems that this is really the case, the special features of the things produced by the system, even Qin Lanyu, a great craftsman, can't understand it, and can only attribute it to the special material, it seems that this is to give yourself benefits, not to want to mass produce a large area of your own.

And this time the prize given to himself, a camera and a book of "Detailed Explanation of Video Surveillance Formation", which obviously wants to mass produce a large area by himself.

"But you want to return it?"

Qin Lanyu shook his head and said, "If you buy it and leave, what's the matter with returning it?"

"Then I really have to compensate you, I have a rare formation, why don't you take a look?"

Seeing that Du Jing was holding a drawing in his hand, Qin Lanyu's eyes suddenly lit up, and he snatched the drawing and looked at it hungrily.

"It's a bit similar to the transmission note, like the formation of this metal plate connecting to the eyeball, but there is also another subtlety and complexity, once it is made, the image must be more than a hundred times clearer than the formation on the eyeball!"

Qin Lanyu looked at the drawings as if he was in a demon.

"This part is similar to the recording note, but it is to store the image, which requires far more space than the symbol can carry. ”

"Wonderful! I actually chose to use spirit stones to provide storage space, and this magic weapon consumed the energy in the spirit stones to make room for storage and stored the picture and then stored it in the spirit stones again!"

"When viewing the video, you only need to remove the spirit stone and urge it with spiritual power to play the video!"

This drawing made Qin Lanyu look at it for about an hour, and finally he put down the drawing and looked at Du Jing with admiration, and said: "I'm convinced! Du Zhutou let me see such a subtle formation today, and I'm completely convinced!"

"Can it be mass-manufactured?"

Qin Lanyu picked up the drawing again and looked at it carefully, and said uncertainly: "There may be a risk of failure, I can try." ”

"Don't be afraid of failure, I want a thousand!"

A thousand, Qin Lanyu gasped.
