Geng Keke nodded with a smile and said, "The bat poison in her has been lifted, and it's no big deal." As for the injury on her arm, it was not a major problem, it was just a slight bone crack, and with her evolutionary physical fitness, it would not take more than a week to heal. ”

Hearing that Chai Xiaowan was fine, the crowd gathered gradually dispersed, and in the end, only Chai Hongyu's mother and daughter, Geng Keke's sister and brother, and Jiao Bai were left in the house. Everyone was an acquaintance, sat together, and soon chatted, mainly Jiao Bai was explaining some of his experiences during his trip to Qinglong Town. This trip is also very exciting, Jiao Bai told them about the corpse tide encountered at the subway base, and the rat tide encountered on the way back to the city, as well as the treasures treasured by the Golden Rat King and so on.

The four of them were very fascinated by what they heard, and every time a thrilling scene appeared, Geng Keke and Chai Hongyu would shout and marvel, as if they were the ones who had experienced all this. Geng Tongtong was envious when he heard it, how he wished that he could also have the strength of Jiao Bai, and he could wander around in this last world, seeing different places and different scenery.

In the evening, after having dinner jointly made by Geng Keke and Chai Hongyu, Jiao Bai came to the factory area in the air-raid shelter and released some of the equipment needed by Yu Yongkang and Qu Yuquan from the carry-on space. With these things, a lot of stagnant work can be carried out, and Jiao Bai's requirements for them are not high, and there is no need to make any innovations, as long as some advanced technologies before the end of the world can be restored. And the first goal is graphene preparation technology, this trip to Qinglong Town, Jiao Bai also gained a lot of relevant information, and gave Yu Yongkang a copy of it. I believe that with the help of these materials and the complete set of production equipment as a reference, it is not difficult for the institute to restore the whole set of technology.

After returning to his room, Jiao Bai turned around and went back to Earth. As soon as I came out of the room and came to the living room on the first floor, I saw Zhihe walking in with a six-rotor drone that had fallen miserably.

Jiao Bai asked curiously: "Zhihe, when did you start playing with drones?" ”

Zhihe threw the drone and some miscellaneous things that fell down on the coffee table, sat on the sofa, sighed, and said, "This is not for fun, but for aerial photography." The company recently received a business to help a travel company shoot a promotional video, which needed some aerial footage. Hiring a helicopter is too expensive, and you have to report to the air traffic control department, which is very troublesome. Those people under him proposed to use drones for aerial photography, and as a result, you also saw it, just after taking two shots, it went out of control and blew up. ”

Jiao Bai came to the broken drone, pulled it and looked at it, but didn't see the reason, so he asked: "Have you bought fake and shoddy products, the current drone should be quite mature." ”

Zhihe shook his head and said, "How can it be a counterfeit product, this is the best and most expensive aerial photography drone on the market." The reason why it was out of control was that it flew too high and encountered a high-altitude current, the wind resistance of this thing was too poor, and the battery was not used, so it only struggled twice and fell out of control. ”

Seeing this drone, Jiao Bai suddenly remembered that there was a set of drone production equipment bought from the Jinshan base in his carry-on space, and he didn't know how the drone produced by that set of equipment was compared to the existing ones.

"How much did it cost to buy this drone?"

"More than 20,000 yuan, this is a professional aerial photography model, and the price is very expensive. What, brother, can you get a drone from the end times? As far as I know, the drone technology over there is very advanced, whether it is the flight control, battery, image transmission, or remote control, it is much stronger than that on this side of the earth. If you can get one, it's not trivial to take some aerial shots. ”

Jiao Bai closed his eyes and rummaged through his personal space with his consciousness, and finally found a shoebox-sized box in the corner. As soon as the mind moved, the box appeared in his hand. Jiao Bai handed it to Zhihe and said with a smile: "You can test this, if the effect is good, we will have another way to make a fortune." I have a drone production line and can open my own factory to produce this kind of drone. ”

Zhihe took the box and opened it in three or two clicks, inside was a folded drone, a small remote control, a charger, and a simple manual. Zhihe first picked up the manual and looked at it, it was all in Chinese traditional, and there was no reading difficulty for Zhihe.

"The data of this drone is so perverted, the empty time is three hours, the remote control distance is 100 kilometers, there are two cameras, both of which are 8K, and it also has a 3D photography function. And what is this pair of ground detection radars and fire control radars for, can this drone still carry weapons? ”

Jiao Bai nodded and said, "It's really what you said, this drone is a military product over there in the end times." Before you take it out, remember to go to the Star Research Institute, and ask them to help you dismantle the fire control radar and modify the parameters of the GPS system. The positioning system on the post-apocalyptic side is not the same as that on Earth, and the frequency and decoding method must be modified to use it. ”

The disassembly and assembly of this drone is relatively simple, as long as the rack is opened, and then the buckle can be locked, only the propeller and battery need to be installed, Zhihe took less than ten minutes, the assembly was completed, and the drone flew with a remote control. After this drone is deployed, it is also half a meter in size, which can be regarded as a medium-sized drone. is such a body type, it can even flash around in the living room, fly very calmly, encounter some obstacles, can also intelligently choose the route, avoid the past, showing an excellent level of control.

Zhihe flew around with the drone, played for a while, and then dropped it back on the coffee table. She took the manual and pointed to the line marked on it, and asked, "Where can I find the mobile phone software that connects to the drone mentioned in this manual?" ”

Jiao Bai touched his chin, thought about it for a while, and finally remembered that when he bought the drone production line, he sent a few mobile phones and a few computers, and he thought that the relevant software should be found in it. Jiao Bai took out the mobile phones and computers and handed them to Zhihe. With ready-made software for reference, Zhihe quickly wrote a program for use on her Android phone, and then ran outside to the yard with the drone to play.

Jiao Bai had some ideas about the drone industry, so he came to the study and checked the relevant information on the Internet. I don't know if I don't know if I don't check, I was shocked when I checked it, just in China, the market size of the UAV market reached more than 20 billion last year, and it exceeded 100 billion in the world. Moreover, the market size of unmanned aerial vehicles is still growing at a growth rate of thirty or forty percent per year, and the prospects are very broad.
