Chapter 1143 The Returnee's Notes 217
Ouyang Lin was completely confused. "So, what have you figured out?"
There was still a hint of expectation in her eyes as she looked at Xie Ning.
Xie Ning remained silent for a while. In such a short time, she didn't have the ability to research anything amazing.
However, he did modify a camera and a drone. Drone technology is not yet that mature, but Xie Ning had some experience with it before, so he could still make a drone himself.
Of course, this refers to small, controllable drones.
Such a machine is very convenient for exploration, but the problem of power consumption is difficult to solve, and the battery life is only half an hour.
The larger the battery capacity, the longer the battery life. With current technology, there is not much room for improvement in battery energy density. If we want to increase the energy storage capacity to extend the battery life, we need to use more batteries.
This is not difficult at all.
However, this increases the weight of the drone, which in turn means increased power consumption.
In other words, under current conditions, increasing the flight time would inevitably sacrifice the size and weight of the drone, which contradicts the inherent portability and lightness of the drone itself.
Thirty minutes is the optimal combination Xie Ning has calculated so far.
Xie Ning was able to conduct research and manufacturing of drones because Professor Zhong happened to have this project under his wing.
Currently, it's still remotely controlled. Their vision is to combine drones with artificial intelligence, meaning that drones can execute commands without the user having to control them personally.
As for the other camera, it was specifically used to record spirits. She didn't actually modify it much, because current surveillance cameras and other video recording and photography devices can record the ghost's image the moment it appears.
Some images are just a bit blurry, but this camera can record the images of ghosts more easily and clearly.
Ouyang Lin wasn't interested in cameras because she thought they were useless and she wasn't going to use them to document ghosts.
However, I am very interested in the drones that Xie Ning mentioned, since not many people can afford to fly drones these days, and they are extremely expensive.
Xie Ning glanced at the box on the back seat in the rearview mirror and smiled, "I'll make one for you when I have some free time. Drones are really convenient."
She is currently focusing on tackling issues related to battery life and artificial intelligence.
"good!"
Ouyang Lin seemed to remember something, and then said to Xie Ning, "Do you remember Officer Xiao Yu's matter? I completed her request a month ago."
Xie Ning hadn't started her vacation yet, so she went by herself.
Xie Ning was stunned for a moment before she remembered that it was Officer Yu who had treated her to hot pot when she went to Huixian to handle a case before. She remembered that Officer Yu was in a bad mood at the time.
"How is Officer Xiao Yu doing now?" They haven't been in touch for a long time.
After all, she was busy, and Officer Xiao Yu was busy too.
"That's great. Guess where I went to chant sutras and perform rituals to help the deceased?"
Xie Ning naturally couldn't guess, so Ouyang Lin only hesitated for a short while before directly saying, "The execution ground."
Officer Xiao Yu asked her to perform a ritual to help a death row inmate pass on.
“That person is pitiful, but he killed someone and should be punished by law.” The law will not let him off just because he is pitiful.
After all, that person killed three people in broad daylight.
One person against three sounds difficult, but that person did it. After all, he was a veteran and still had some fighting skills. Even against three adult men, it was more than enough for him.
I got to know Officer Xiao Yu because we were from the same village.
According to Officer Xiao Yu, one of the three men who were killed had sexually assaulted the man's mother when he was a child, and then he and his two sons beat her to death.
But in the end, the man who committed the murder got away with it because he had some connections. He then sent his youngest son to take the blame. Because his youngest son was a minor, the court only sentenced him to seven years. After a series of sentence reductions, the youngest son only served three years in prison before being released.
Even though one person died, the family continued to live well and even started a successful business, becoming the most prosperous in their village. No one remembered the innocent woman who was murdered anymore.
No one remembers the family that was torn apart because of this incident. Shortly after the mother died, the father also passed away from illness, leaving behind only an older sister who was also struggling.
Now divorced, she stays home to farm and raises her daughter alone.
