When Lu Yiyuan saw this, his face changed slightly.

He's been unboxed?

This is the first time that he has been seen through his true identity after making a disguise.

How did the other party do it?

He cast an inquiring glance at the other.

Twilight understood his eyes, and wrote a sentence again:

[Senior Sister Yu has made a strange thing that can see through all the disguises. 】

"All?" Lu Yiyuan was surprised.

Twilight nodded, then wrote again:

[Rest assured, there is only one strange thing, and others can't see through your disguise.] 】

"Oh......" Lu Yiyuan replied with a long voice, and then asked curiously, "Since you already know that I am the Blood Erosion Demon Lord, you still dare to chat with me?" Aren't you afraid of me? ”

Twilight: [Don't be afraid. You're not the same as the rumors. 】

Lu Yiyuan couldn't help but smile: "We've only met for less than twenty breaths, right?" How can you be sure I'm not the same as I was rumored? What if I'm all in disguise? ”

Twilight: "I'm not afraid. You can't catch me. 】

Lu Yiyuan raised his eyebrows: "Do you still have a backhand?" ”

Twilight nodded.

"Well, you can see it. Yes, I'm a great person. ”

Lu Yiyuan chuckled and said, "You can trust me like Senior Sister Yu who trusts you." ”

Twilight looked at him for a moment, and finally wrote a sentence on a blank piece of paper:

You can't trust it yet. 】

"But you already trust me." Lu Yiyuan said seriously.

Twilight quieted down and stopped writing.

Lu Yiyuan thought for a while, and then asked, "Do you know Shen Suzhi?" ”

Twilight: [Acquaintance.] 】

"That's good, I'm actually good friends with her."

[I don't believe it.] 】

"If you don't believe me, I'm going to ask!"

[I can't reach her.] 】

"I can't contact ......" Lu Yiyuan was a little surprised, "You don't know her well?" ”

Twilight pursed her lips, but didn't respond.

"But I heard that she seems to like you very much?" Lu Yiyuan asked.

Twilight averts her gaze, still not responding.

"Okay, okay, let's stop talking about that."

Lu Yiyuan wisely chose to end this topic, and said seriously, "You give me what your Senior Sister Yu gave you." ”

Twilight turned her head back and reached into the spatial bag to find two artifacts about the size of a smartphone.

Lu Yiyuan stepped forward to take it with some surprise.

He also thought that Yu Yingxue's first experimental product would be very large and bulky...... That's the most common sense situation.

In his previous life, the combinators and cameras were also iterated for many years before they gradually became delicate and powerful.

Right now, just the first generation of experiments, Yu Yingxue can make it look like this...... He can't imagine what the new products that the other party will iterate on in the future will look like!

Twilight took out another blank piece of paper from her arms:

[I'll go back first.] 】

Lu Yiyuan nodded: "See you soon." ”

Twilight put away the pen and paper, mounted the machine ox, and flew back to Mu Xuanzong.

Lu Yiyuan watched until her figure disappeared, then he lowered his head and began to carefully examine the two mechanical creations in his hand.

The first is the combinator.

It is slightly larger than the other mechanism artifact, and the overall appearance is that of a delicate flat wooden box.

The surface of the box is divided into two areas.

One area is a white "screen" of unknown material;

In the other area, there are buttons composed of the words "zero" to "nine", as well as the units from "ten" to "billion", as well as the words "addition" and "subtraction".

Seeing this, Lu Yiyuan suddenly remembered that he had forgotten to teach Yu Yingxue Arabic numerals and operation symbols!

I have to teach her some simple formulas and algorithms these days...... Fortunately, the knowledge and memory of previous lives can be extracted. Otherwise, let a junior high school student cross over, it is estimated that he will be better than me......

Lu Yiyuan muttered silently, and casually did the addition problem of "nine plus six" on the combinator.

On the white screen, the answer "fifteen" soon popped up, and it took no more than a breath before and after.

The font displayed is very stiff and rigid in the texture of the printed body.

But these are really "pictures" and nothing else.

'Yu Yingxue: This is the signal conversion technology, applied to the combinator? ’

Lu Yiyuan took a closer look at the operation inside the combinator; It was found that there were indeed traces of spiritual power turning into electricity, and the electrical signal was finally converted into a picture.

In other words, the white "screen" on the combinator is actually a real "display"!

Originally, I thought that we were still far away from making computers; Now it seems that it is just around the corner! ’

Lu Yiyuan put away the combinator and turned his attention to the camera.

The appearance of the camera looks much simpler.

There is only a large "screen" on the surface, and three buttons next to it.

"Screen" is naturally "display"; The three buttons correspond to the three functions of [Record], [View], and [Delete].

Lu Yiyuan tried to use it for [recording] and [viewing], and finally found that except for the poor quality of the recorded picture, there was basically no other problem.

However, it's worth mentioning that the camera can only record up to 10 seconds of footage at a time, and if you want to record a second frame, you have to delete the previous one first.

'This degree of completion, I would like to call you the strongest in Mu Xuanzong...... Well, until I meet the next one who is stronger. ’

Lu Yiyuan thought silently, took out the communication jade talisman, and planned to contact Yu Yingxue.

In the next moment, he was the first to receive a message from the other party.

Yu Yingxue: [Will you use it?] 】

Lu Yiyuan: [Yes.] 】

Yu Yingxue: [How's that? 】

Lu Yiyuan: [[Kneeling] You're a genius! 】

Yu Yingxue: [Listen to Senior Sister Xiaodu, you are the Blood Eclipse Demon Lord? The way you're now......]

Lu Yiyuan: [So, I'm a good person. 】

Yu Yingxue: [You're a weirdo. 】

Lu Yiyuan: [Okay, okay, let's get down to business.] Let me tell you what I think needs to be improved about these two mechanical creations...... Well, the problem is not with you, but with me; Blame me for not telling you that clearly. Actually, in terms of number crunching......]

Lu Yiyuan introduced to the other party in detail, Arabic numerals and "addition, subtraction, multiplication and division" and other operation symbols, hoping that the other party could simplify the combinator;

Subsequently, he explained that between the [Record] and [View] of the camera screen information, one can be added, the function of classified storage and accurate extraction; With a single camera, you can record multiple images, and you can let people view the recorded images sequentially and repeatedly.

Yu Yingxue: [Your idea is very powerful. 】

Lu Yiyuan: [[Ashamed]]

Yu Yingxue: [So, can we also record the sound?] 】

Lu Yiyuan: [Of course! 】

Yu Yingxue: [Well, I'll do research. And, about new ideas......]

Lu Yiyuan: [Do you think that combining the creativity of these two mechanism creations with the communication jade rune, so that the communication jade rune can not only transmit the screen, but also allow ordinary people to communicate through key input...... How about such an idea? 】

He began to think about the prototype of a smartphone.

Yu Yingxue: [Okay, I'll try.] 】

Lu Yiyuan: [You don't care that I'm the Blood Eclipse Demon Lord? 】

Yu Yingxue: [I don't care. 】

Yu Yingxue: [Because we are all weirdos. 】
