At this stage, the performance of digital equipment was improving by leaps and bounds, but the rope around their necks was the battery.
Even the noble kidney machines had nightmares of charging three times a day. A portable power bank like a urine bag used to be a necessary piece of equipment for many people.
After flying for about half an hour, the elfins were still not satisfied. Nekhbet's battery was already down to a quarter, close to a dangerous level.
After he gave the order, Nekhbet began to automatically return, landing almost exactly where it had taken off. The rotors quickly stopped spinning.
The elfins looked at it again, no longer with contempt or doubt. They were full of envy and amazement.
Because of Wei Kang's high requirements, he had to ensure that the drone was always hovering overhead during field expeditions. Therefore, he was extravagantly equipped with several sets of spare batteries for rotation use. Anyway, this was funded by Binhai University, and the request was very reasonable.
Zhang Zian replaced Nekhbet's spare batteries. He was worried that its internal parts would overheat due to continuous flight, so he waited for a while. In fact, it was only slightly warm.
Using this time, he took out another device to attract the elfins' attention.
"What is this?" they asked one after another. With the previous experience, they did not dare to underestimate these unassuming technological products.
"This is an infrared camera that I asked Professor Wei Kang for," Zhang Zian explained. "It is said that this thing can automatically take pictures. Once a warm-blooded animal or moving object passes in front of the lens, it will automatically press the shutter and take a picture."
Although this thing was rare, it did not attract the elfins' interest like the drone. It was just taking pictures. What was the difference between a person taking pictures and a camera automatically taking pictures?
Zhang Zian patiently explained his thoughts.
When he saw the infrared camera in Wei Kang's office, he immediately had a corresponding worry. Could this thing work on invisible elfins?
After learning about the principle of the infrared camera from Wei Kang, he was even more worried. The infrared camera was designed to be on standby in the wild for a long time, day or night. It was fine during the day, but even at night, once a warm-blooded animal or moving object was detected, the light-emitting diode would emit a faint red light and take a picture of the target.
So, if the invisible elfins passed in front of the camera and triggered the camera's sensor, would the camera automatically take a picture of the elfins?
Even if it did not, the expedition team would think that a supernatural event had occurred and panic would arise.
As for saying that the camera was broken, it was unrealistic because the expedition team had brought many cameras of the same type. They couldn't all be broken at the same time, right?
Therefore, he shamelessly borrowed an infrared camera and planned to test it out in advance, just in case.
Only then did the elves understand his intentions.
Old Time Tea volunteered and asked Zhang Zian to make it invisible. Then, it walked in front of the infrared camera in its invisible state and walked back and forth several times at different speeds.
Zhang Zian took out the memory card of the infrared camera and inserted it into his phone to read it.
Fortunately, the memory card was blank, which meant that the camera's sensor did not detect the invisible elfin. Only then did he feel relieved.
His concerns were polarized by the elfins. Old Time Tea praised him for being meticulous, while Snowy Lionet scolded him for being overly cautious …
Putting away the infrared camera, he touched Nekhbet's outer shell. It was already cold, so he prepared to start the second round of testing.
The first round was a simple flight test. This time, he changed to a new test method. He switched to follow mode and made Nekhbet use him as a target, keeping it hovering above his head. This was a simulation of a field expedition.
"Xinghai, are you ready to be defeated? Now it's time to end your winning record! "
Everything was ready. He confidently issued a hide-and-seek challenge to Xinghai, and he was not ashamed of using cheats.
"Meow! I'm ready!"
Xinghai was already eager to try. It couldn't wait to try the few good hiding spots that it had seen from the sky.
"Alright, I'm going to start counting. This time, I'm counting with my eyes closed! One, two, three … "
He closed his eyes, not bothering to hide the fact that he had peeked while he was counting.
"Meow! Shameless! You're counting too fast! "
Xinghai kept complaining. Its voice became erratic, and it seemed to go from near to far in an instant.
After more than half an hour, the elfins, who had woken up early, were a little hungry. Fina had just seen through the drone that Uncle Li had already sent breakfast to the pet shop, so she hurried back to the shop to eat. Snowy Lionet, of course, followed suit. Old Time Tea and Famous liked to eat hot food, so they also went back to eat. The stray cats returned to the green space one after another. Vladimir received some fresh news and intelligence. It had something to deal with, so it temporarily left.
Richard didn't leave. It didn't need to eat hot cooked food anyway, and it could urinate and poop freely here.
"98, 99, 100! I'm going to start looking for you! "Zhang Zian quickly counted to 100 and opened his eyes.
He gave Richard, who was watching from the side, a look that meant to ask where Xinghai had gone, but Richard only rolled its eyes.
"Ga ga! You idiot! Do you think you're omnipotent with a drone? Anyway, in my opinion, a drone is not as good as a chicken! "
Zhang Zian didn't count on it anyway. Through the screen of the remote control, he rewound the video of him counting. This was already blatant cheating.
However, Xinghai's actions were too fast. In the first second, it stayed where it was, in the second second, it turned around, and in the third second, it disappeared.
Exo me？
It seemed that Xinghai was finally getting serious.
Zhang Zian didn't admit defeat so quickly. He started to play the video frame by frame.
The PTZ camera equipped with the drone could record 4K video at a speed of 60 frames per second, which meant that it could record 60 moments with a snap of the fingers.
Unfortunately, he watched all 60 frames of the video, but he still didn't see the process of Xinghai disappearing.
It was there in the 30th frame, but it disappeared in the 31st frame.
It seemed that it was time to give feedback to the manufacturer and ask them to provide a video mode with lower definition but higher frame count, such as 1080P/960 frames?
However, he was skeptical. Even if it was increased to 9600 frames, could it capture Xinghai's movements?
He circled the green space twice, startling countless insects and covering his face with pine needles, but to no avail. In the end, he could only admit defeat because the staff had already started working, and he could not continue to waste time here.
"Forget it, Xinghai. I didn't prepare well this time. I'll let you win this round!"
He lost, but he didn't want to admit defeat.
"Meow! I won!"
Xinghai suddenly came out of nowhere and cheered for victory.
