After Lu Yiyi and the others got out of class, Lan Zeguang and they went to the Mandarin Music Bar to eat. It was supposed to be just a good bar, but because the chef was more powerful, it became a canteen at meal time. Not only Lan Ze patronized, but some wealthy young masters were also invited here.

In the past, when she came here, Lu Yiyi wanted to touch the piano. But today, Lu Yiyi sat down with Lan Zeguang and Lucifer.

"Lucifer." Just sat down, ordered, and the waiter left respectfully. Lu Yiyi said sternly: "Can I have the same superpowers as you?" This way I can protect myself, and then everyone will not be so embarrassed. ”

"Yes." Lucifer, who had been looking for an excuse to reject Louyi, suddenly agreed. But he said: "But it's useless, you are not Lan Ze Guangsang, even if you have the same ability as Lan Ze Guangsang, you can't deal with the killers of hell with you, unless you find a more suitable way for your self-preservation." ”

As soon as he heard Lucifer's promise to Lu Yiyi, he was immediately excited, but Lucifer's next words disappointed Lu Yiyi. But she still wanted to fight for it, saying, "It's better than nothing!" ”

"No, I don't think it's better to have no." Lucifer righteously repudiated Louyi's point of view, saying: "The group of people from hell will definitely find someone who has a relationship with me first, and if Luyiyi also has my ability in you, I'm afraid it will be even more dangerous." ”

"That'...... So what the hell are you going to do with me? Lu Yiyi was in a hurry.

"I said it yesterday, leave Lan Zeguangsang. In this way, people who have nothing to do with it will ......"

"Alright, alright, Lucifer, don't talk so much. Didn't you say that? Haven't I already made the positioning communicator?,I'll go to the real yàn room tonight to draw a picture.,See if I can hand it over to the factory tomorrow to make a few test products.。 Seeing that this man and woman were about to be tense again, Lan Zeguang hurriedly joined in.

Then he comforted Lu Yiyi and said: "When the time comes, put that transmitter on your body, and call Lucifer immediately if you are in danger, and then you won't have to worry so much." ”

After speaking, he doted on Lu Yiyi's hand.

Since yesterday. Lucifer had a good reason to threaten Lu Yiyi to let her leave Lan Zeguang's side, of course Lan Zeguang knew that Lu Yiyi was not very angry, so he had to lean towards her emotionally. And Lucifer knew he was wrong. Seeing Lan Zeguang and Lu Yiyi showing affection in front of him, although it was not a taste, he could only swallow this unhappiness in his stomach silently.

As a dignified demon king, he also knew that taking advantage of people's danger to drive Lu Yiyi away at this time would definitely cause Lan Zeguang's disgust.

So. He didn't say anything.

There is the comfort of blue light. Lu Yiyi no longer argued with Lucifer, but Lu Yiyi was still worried, and Lucifer was also stubborn.

Well, since everyone is like this, let's talk a little bit about it!

"I mean, it's not good to be so dull." Lan Zeguang stirred the drink in the cup and said, "I ask you a question: Xiao Ming's birthday is in November, do you know what it means?" ”

"Huh?" Lu Yiyi was stopped by Lan Zeguang's question: "What does it mean?" Singles? ”

"Phew. Lan Zeguangsang's joke is not interesting at all, but Lu Yiyi, you can't guess it! Lucifer seemed to understand it all at once. Proud and provocative Lu Yiyi.

"Humph! You know again?! Lu Yiyi shot back mercilessly.

"Of course I know, human pregnancy is generally nine months, so that is to say, Xiao Ming, who was born in November, his parents must be very likely to have created a man on the night of Valentine's Day!" Lucifer explained triumphantly.

"Phew...... Erotic artist! ”

……

Although it was a tasteless joke, as soon as Lan Zeguang said this, the atmosphere immediately became lively. At least, there is no more argument about leaving and not leaving.

For dinner, Lu Yiyi went to play the piano for a while, and when Mr. Gong sent someone to send the large Maoyu that collected souls yesterday, Lan Zeguang took their souls away, absorbing and converting them. And then it seemed to be getting softer and softer.

In the evening, Lan Zeguang decided to go to the real yàn room to paint, and today he designed a day's "location communicator" - this thing that can communicate location information in times of danger, so for the time being. Lu Yiyi and Lan Zeguang had to follow her to the real room, go back to the dormitory and get some homework, and the group arrived in the real room.

With a higher task priority, Lan Zeguang put down his quadcopter for the time being, opened the AltiumDesigner software that drew the circuit schematic and PCB diagrams, and began to draw the schematic of the communicator designed today.

After a day of tossing, the position communicator in Lan Zeguang's mind has a prototype: measuring the size of the chip and battery capacity, you can use a microprocessor like MSP430, plus the smallest GPS module and integrated Bluetooth, WiFi, GSM communication module, with a small 100mAh battery, you can make the communicator the size of a peanut shell.

However, the circuit design and anti-interference aspects need to be put into a little effort. This design problem is not so easy to solve, and even if Lan Ze Solar can obtain the knowledge of circuit and industrial design masters, it will take a lot of effort to start making such a difficult thing.

As for the program, Lan Zeguang called Dong Chen today and asked him to help write it.

Speaking of which, Dong Chen has been entangled for two days since he knew the reason why he didn't have a girlfriend, but the good times didn't last long. After returning to the real yàn room, he immediately devoted himself to writing code, and even forgot that Lan Zeguang asked him to log in to this website to take a look.

It's really a program ape, and it really deserves it.

After Lan Zeguang drew the schematic, he went to the professor in the real yàn room and asked for a set of MSP430 development boards for Dong Chen.

"Take it, help me study him, GPS module, wifi, gsm, bluetooth, are guaranteed to run on it, can use CAN bus if you can use it, no problem, right?" Lan Zeguang greeted him straight to the point.

"What's that? What are you doing here? I still have my own stuff to do, what are you doing......"

"100,000 dollars!" Lan Zeguang didn't say a word, and stretched out his fingers. However, because the blue light in the absorption and transformation soul is paired with the pink cloak, it looks soft, so it seems that there is nothing deterrent.

"......" But even so, Dong Chen was still frightened by Lan Zeguang's invisible momentum and couldn't speak. Although he is a programmed ape, he still cares about the soft girl coins that must be used in life. Lan Zeguang saw that he didn't agree, so he continued: "If it's not enough, give you a full set of knowledge of single-chip microcomputer and embedded development, and industrial control algorithms can also be used." ”

"Wait, wait, wait! What are you talking about? Dong Chen was confused. Of course, this temptation was very strong, but she didn't react for a while. It's understandable to pay for outsourced software development. But what the hell is "giving knowledge"?

However, Dong Chen quickly reacted, thinking of the "second shot" scene when he was pumping his soul for twenty years on Saturday night, and immediately felt that Lan Zeguang might not be lying.

There was no need for Lan Zeguang to repeat, Dong Chen slapped the table and replied, "Okay!" I do! ”

"Welcome to the World Truth Research Society!" At this time, Lan Zeguang could smile and stretch out his hand.

"What?"

At this time, Dong Chen suddenly found that the girl in front of him, who was a head shorter than himself, seemed to have abducted herself onto the thief ship.

……

The rest of the days are a bit busy, except for daily work, most of the blue light is immersed in the design of the position communicator. Xi spent two days on the design, contacted Mr. Gong directly, asked him to find a local factory, made a set of PCB, and then went to the electronics company to get a batch of components needed by Lan Zeguang back. However, some of the more men who have obtained them, such as specially designed 100mAh batteries, will have to wait a little longer.

After all, the orders of large companies are preferential, and they don't need so much Lan Zeguang, which is more troublesome. But fortunately, there are a lot of wearable devices on the market recently, so the supplier of 100mAh got the battery from a nearby foundry through some indirect relationships, and even ...... Even the mold for the shell is there.

I have to say that this is a mistake by Lan Zeguang. The first time she was engaged in industrial design, the girl made a mistake - she didn't care about the cost. If you do a good job of investigation at the beginning and know that some foundries have other abrasives and batteries manufactured on the field, Lan Zeguang does not need to worry about these, but directly uses that mold as the standard to design the PCB circuit.

But...... It's also a whole new challenge.

A week later, Lan Zeguang assembled the finished product in the real room. And after such a long time, Dong Chen also debugged the program requested by Lan Zeguang. Lan Zeguang only needs to get his hands on it, modify, transplant and adapt, and it can run on the position communicator the size of a peanut shell.

Then, it was time for Dong Chen to make a server that could collect this information.

Lan Zeguang is very smooth here. And the strange thing is that after experiencing the turmoil of Xiao and Xianglong Guyue, in the past more than a week, Lan Zeguang and his party have not encountered danger. None of Lucifer's "servants" were killed, as if the danger from hell had disappeared.

But even so, for Lu Yiyi, it is still tormenting.

If she can't get rid of the ugly hat of "stumbling block" for a day, she will not be happy for a day. The anxiety in her heart even made her can't help but silently pray to the god in her mind in private: "Virgin Mary, if you can hear my voice, please bless me to be with Lan Zeguang!" ”

Obviously in the company of evil, can Lu Yiyi's prayer really come true?

As it turns out, nothing is impossible...... (To be continued......)
