Li Shan followed the address on the business card and found Lao Gu's shop.

The store is located on the first floor of a residential building in a residential area.

The small shop with the sign of "Lide Technology Service Society" hanging in front of the house looks inconspicuous from the outside, and a chair placed at the door is still drying a quilt.

Looking at all this, Li Shan muttered in his heart, he really doubted whether this old Gu had this ability.

No matter how you say it, the modified drone looks like the legendary kind of high-tech, and then looked at the words such as the modified drone on the business card, Li Shan still gritted his teeth, thinking that since he finally came, he simply went in and had a look.

When he entered the door, Li Shan almost collided with a young man who was dressed coolly, a big bag in this person's hand was very conspicuous, and a pair of very exaggerated big sunglasses on his face covered half of his face, and Li Shan glanced at each other, hurriedly said sorry, and then lowered his head and left in a hurry.

Li Shan glanced at the young man's back, then turned around and entered the store.

As soon as he entered the door, a sour smell penetrated his nostrils in an instant, and Li Shan almost didn't vomit out of his overnight meal.

"Is there anything wrong with you?" At this time, a person in the room asked lightly, and the voice was that old Gu.

The light in the house was not too bright, and entering the house from the well-lit outside, Li Shan was still a little uncomfortable for a while.

"I remember, aren't you the same young man at the summit party? Lao Gu had already recognized him, and got up to greet him warmly.

After a while, Li Shanqiang endured the unpleasant smell, and his eyes were somewhat accustomed to the light in the room, and then he saw Lao Gu sitting in the pile of debris, looking at him with a smile.

"Hello, Teacher Gu, I took the liberty to disturb you today. Li Shan asked him at this time, so he lowered his posture very low.

"If there is any need here, just mention it, little brother. As soon as you and I hit it off, just call me Lao Gu. I don't want any teachers to be long and teachers short, I don't like to hear this!" Lao Gu hurriedly corrected Li Shan's title for himself, and seemed to care about this.

"That'...... , okay!" Li Shan hesitated for a moment, then agreed indifferently, feeling that this person was really a reckless person.

"That's right, now let's talk about the purpose of this. Lao Gu nodded and said with satisfaction.

I really couldn't stand the smell in this room, and wanted to leave here as soon as possible, so he briefly said the purpose of his coming, and at the same time, he wondered in his heart, can't this old Gu smell it himself.

"Hehe, you also want to take this road, have you thought about it before this?" Lao Gu listened to Li Shan's words, pondered for a while, and then asked.

There is nothing to consider about this, and this is not an illegal thing. Li Shan was a little puzzled in his heart, he hadn't heard that the modified drone would violate any relevant systems, but it was more strictly controlled when flying.

"Thinking clearly, I need to retrofit a drone. Li Shan said affirmatively.

"Okay, I can give you a transformation, what kind of requirements do you have?" said Lao Gu.

So Li Shan said some of his thoughts, and especially emphasized the need to install infrared emitters. Li Shan's idea is that the infrared emitter can be replaced at any time, but in fact, his real purpose is to replace the laser in the future. The reason he gave was that if there was a problem with the infrared emitter, it would be easy to replace.

Lao Gu said with a smile: "I understand this." "It's all in plain sight.

"Let's make sure you need to be able to fly for at least 30 minutes, in addition to the laser sight, there is a convenient IR emitter that can be easily replaced, as well as a GPS controller, a 1008P wide-angle camera, and of course, a professional-grade remote control with a monitor, right? ”

"That's right, that's it. Strange to say, maybe he got used to the smell in the house, Li Shan didn't feel as unacceptable as when he first came in, maybe it was in response to the words: I don't feel the smell after being in it for a long time.

"In addition, I also recommend that you install a walk-com, if you meet other drones in flight, as long as the distance is within the right range, you can talk to each other, usually this kind of thing is installed on drones now, which is almost a standard. ”

Finally, at the suggestion of Lao Gu, some functions were added on the basis of the original.

"Then you can calculate the following cost. After confirming the conditions he needed, Li Shan raised the issue of the cost of modification.

"It's fifteen thousand in total. Lao Gu quickly made an offer.

"What, so expensive?" Li Shan originally thought that it would be four or five thousand, but in this way, he gritted his teeth and barely managed to take it.

At this time, looking at the shrewdness in this old Gu's eyes, how could he have the kind of sincerity in his original impression.

At this time, Li Shan finally understood the other party's intention to call him Lao Gu instead of calling him. This person obviously felt that if he was an elder, it would be difficult to make a blatant offer, so he played such a small trick to cover his ears and steal the bell.

"It's not expensive, it's just that for the sake of our fate, I already take good care of you, basically I don't earn you any money, it's completely a friendship price. "Lao Gu is also pouring bitter water.

"Then I can't afford it, so let's see if I can give some less important configurations. Li Shan came up with an idea.

So, the two re-planned the configuration, first subtracted the GPS tracker, and the remote control and battery were also replaced with the lowest-end kind, originally Li Shan wanted to save the intercom, but Lao Gu said that it was only a few dozen yuan, and it would not save a few dollars if it was removed.

In the end, it will cost 9,900 yuan, which is still very high in Li Shan's eyes.

Seeing that Li Shan was a little hesitant, Lao Gu rolled his eyes, and proposed a plan that could be paid in installments, which made Li Shan reluctantly agree.

Lao Gu quickly opened an agreement and handed it to Li Shan for him to sign, which was so fast that Li Shan was a little smacked.

After Li Shan took the agreement, he carefully looked at the content inside, this is an agreement that has been made for a long time, and he only needs to fill in the relevant content in some blank spaces above.

Feeling that there was no problem on it, Li Shan picked up the pen and signed his name, which was an agreement in duplicate, Li Shan took out one of them, and handed the other one back to Lao Gu.

Even if everything is done, he suddenly looked at Lao Gu staring at himself fixedly, a little puzzled for a while, pondered for a while, suddenly thought of something, patted his head, and immediately took out the prepared deposit of two thousand yuan and handed it over.

After Lao Gu took the money, he counted them one by one, he counted one and rubbed it with his hand, and glanced at the watermark on the coin at the light, and after a while, he nodded with satisfaction and said with a smile: "Brother, this time you can be regarded as picking! ”

Li Shan nodded noncommittally, but did not say anything.

At this time, Lao Gu's face was undoubtedly exposed, which was completely different from the approachable image he saw at the beginning.

After the two agreed to deliver the goods in a week, Li Shan left the store.

On the way back, when I thought of the old Gu who seemed to be a simple and honest profiteer, his smile was so bright when he went out, and I always felt that I was calculated by him.

I think that at the beginning, the old drone he gave to himself was not worth a few dollars in itself, and the purpose of giving it to himself was nothing more than to lead himself onto this boat, which was nearly 10,000 yuan. He said it nicely, what was like a familiar thing at first sight, what was young and promising, it was all intentional, and he was dizzy when he heard it, and now I think that this old Gu is really an old fox.

It's the weekend again, Li Shan and Han Xin have made an appointment, and the two want to invite Wang Quanbin and them to dinner.
