Lin Chujian's panic made Jiang Mubai feel puzzled.

It's not hard to understand that drones can fly.

In the absence of a satellite navigation system to determine the global coordinates, the rebels can complete the mapping in advance and use the local coordinates to locate the drone.

Even if the drone is not positioned, it can be manually operated by an operator trained to fly without navigation.

However, the UAV must have a complete signal transmission equipment system to complete the communication task, Xiaoshan has no available base station and central server, and the UAV can only use local signals to transmit pictures.

Although the drone is equipped with cameras and video recording equipment, if it cannot transmit the footage in real time without delay, the operator can only observe the position of the drone with the naked eye, and cannot search for targets through the drone.

Unless......

Unless the drone will find someone on its own.

Jiang Mubai looked up at the hovering drone, and his heartbeat, which had been accelerated by running, accelerated again.

The dependence of drones on GPS, Beidou and other satellite navigation systems has been criticized, so thousands of researchers have devoted themselves to various fields to try to break through the bottleneck.

In addition to the Navsop navigation system developed by the empire on which the sun never sets, Jiang Mubai also remembers the FLA project of the US Federal Defense Advanced Research Projects Agency.

In the second phase of the obstacle flight test, the quadcopter used by the Darpa research team used to test the quadcopter used on-board cameras and sensors as visual organs, and intelligent algorithms to self-navigate, flying at a speed of more than 20 meters per second in a complex environment without human control or GPS navigation, successfully avoiding all obstacles.

The purpose of the FLA project is to get rid of the dependence of drones on manual remote control and satellite navigation systems, so that drones can enter dense forests, basements, earthquake ruins and other environments that cannot be effectively transmitted by GPS signals after a disaster occurs, and search for survivors in need of rescue.

Any technology, or any power, is a double-edged sword.

If you can use it to search for survivors, you can use it to search for hostile targets!

For drones that have the ability to fly autonomously, it is not necessarily difficult to find people in the mountains and forests, and it is enough to install thermal imagers, pattern recognition systems, and facial and human body structure feature recognition systems.

As for signal transmission? There is no need to send back the footage, the position where the drone hovers is enough to point the way to the rebels who come to chase them.

Perhaps, they have a smarter way.

In short, the rebels released the drone, it is impossible to take a picture of the beautiful scenery of Xiaoshan as a souvenir.

"Run! Run to a place with a lot of trees! ”

Jiang Mubai hugged Lin Chujian's legs tightly and ran wildly.

Although Tie Dan didn't understand what was happening, he believed that Jiang Mubai and Lin Chujian's judgment would not be wrong, and followed Jiang Mubai and ran towards the dense trees.

"Chased after me." Lin Chujin whispered in Jiang Mubai's ear.

Jiang Mubai didn't dare to slow down and look back, and asked as he ran, "Are your ice blades enough?" Can you knock it down? ”

The effective range of Tiedan's inferior revolver does not exceed fifty meters, and no matter how good Jiang Mubai's marksmanship is, he will not be able to use a pistol to fight a plane, even if it is a drone.

Lin Chujin didn't answer, she put away the round mirror, held the porcelain bottle in her left hand and poured the pill into her mouth in an unsightly posture, then threw down the empty bottle, changed the umbrella handle in her right hand to her left hand, and poked her eyebrows with a trick that Jiang Mubai couldn't understand in her right hand.

Two ice blades appeared out of thin air and shot towards the drone that was chasing after them in mid-air.

The drone multi-rotor adjusts its direction, dodges two ice blades and dives into the forest.

The blow missed, and Lin Chujian's hands hung weakly.

"No, I don't have enough control over the 'Ice Que'."

This result is not surprising, if Lin Chujin's control of the ice blade is superb, she does not have to deliberately expose her position before, she gets up and uses a paper umbrella to resist bullets, just to make the two rebels become a fixed target while shooting at her.

"Well, it's okay, I'll figure it out." Jiang Mubai's tone was calm, but he was anxious in his heart, because he had nothing he could do.

"I'm sorry." Lin apologized in a weak voice.

Without her phone call, Jiang Mubai would not have gone up the mountain, let alone encountered a life and death crisis inexplicably.

Jiang Mubai snorted and didn't blame or complain.

To say that there is no remorse in your heart is to lie to yourself, but at this point, instead of wasting your tongue saying nonsense like "all blame you" or "I don't blame you", it is better to seize the time to think about countermeasures.

"Put me down."

"What?"

"It's densely wooded here, let me down, I have a way to hide." Lin Chujin bit her lower lip hard, struggling to break free of Jiang Mubai's arms under her legs.

Jiang Mubai did not have the realm of quenching the body, and ran in the mountains and forests with Lin Chujin on his back, even if he was not caught up by the pursuing rebels, he would be caught up by drones.

Although Jiang Mubai couldn't tell whether the drone was carrying a weapon, the drone used by the rebels was likely to have attack methods, because the drone used purely for reconnaissance should be designed to be easy to conceal and not easy to detect.

Thinking of this, Jiang Mubai ran to the big tree on the right side and let go of his hands, panting while beckoning to the iron egg behind him.

Lin Chujin took out an almost transparent scroll from the handle of the umbrella, pinched the trick with both hands, and shouted in his mouth: "Change!" ”

The scroll spread out on its own, covering the heads of the three men like sunshade paper, and then spread out again, encircling the three of them.

Jiang Mubai and Tie Dan looked at the owner of the scroll in unison.

Lin Chujin explained with difficulty: "This is a magic weapon refined by my parents, and it will imitate the surrounding environment and hide our figures. ”

"Can you fool that black iron bird?" Iron Egg asked.

Lin Chujin nodded slowly: "The 'Heavenly Frontier' chasing behind us is also a magic weapon refined by the rebel army, I have seen it in the Tianjing Museum, and it is two grades higher than my 'telescope'. When I used the 'Ice Barrier' just now, the 'Heavenly Frontier' of the rebel envoy entered the woods, and the branches and leaves of the trees would obscure the view, and we ......."

"It's useless." Jiang Mubai interrupted and shook his head in annoyance, "Simulating the surrounding environment can only fool people's eyes, not the thermal imager, our body temperature is higher than the ambient temperature." ”

"Drones? Thermal imager? Lin Chujin looked puzzled and puzzled by Jiang Mubai's nonsense.

"Moreover, we have disappeared in this area, and even if the drones can't find us, it won't be long before three or four rebels come and search for us."

Jiang Mubai didn't have time to explain the noun, and after shaking his head repeatedly, he gritted his teeth and made a decision.

"Teacher Lin, can you make your body temperature drop to the same level as your surroundings?"

During the previous physical contact, Jiang Mubai noticed that Lin Chujian's body surface temperature was much lower than that of ordinary people, and in connection with her unique fighting style, Jiang Mubai guessed that her abnormal body temperature was mostly related to her cultivation techniques, so he asked this question.

"Yes."

Lin Chujin didn't ask why, so Jiang Mubai saved some explanation.

"Teacher Lin, you lower your body temperature and stay here, Tie Dan and I will go and lure the drone away, and when we lure the drone and the rebels away, you use the satellite phone to explain the situation to the Dingwu Zhengfu, and the chief official will definitely send someone up the mountain immediately."

"Okay." Lin Chujin did not hesitate at all, and was unexpectedly decisive.
