Li Tuo and Shang Fengzi worked for an hour to clear a 200-meter-long runway.

A drone with a length of 8 meters, a height of 2 meters and a wingspan of 11 meters was placed at the front of the runway.

Tie Shu curiously watched Li Tuo sitting there scratching his ears and cheeks and flipping through a thick manual, she looked at Shang Fengzi, who was also a little numb, and said with a smile: "This is your killer feature?" When will you be able to get these iron birds flying? ”

Li Tuo touched his nose, he overestimated his level, and wanted to understand that the thick manual was not something he could do at the moment.

But modern technology has the advantage of making the process foolish.

He only needs to control the drone to take off, drop more radio retiners in the right position, and then quickly expand the detection range.

The parameters of the drone provided by the military are great, and the built-in fuel cell can allow the drone to continue to fly in the air for more than 30 hours.

There are five hardpoints on the sides of the wing and in the belly of the aircraft, which can be mounted with five high-energy renewals wrapped in silicone and camouflaged as rocks.

Considering that the signal transmission ability in the air is more excellent, as long as the relay signal released by the golden cicada controls the radius of 800 kilometers to 1000 kilometers, their actions can be bolder and more purposeful in the later stage.

With the assistance of reconnaissance drones, it is equivalent to them having an extra eye, if it weren't for the fact that the missiles carried by the drones have a very general effect on the big demons, it is not impossible for their practical drones to support them.

Li Tuo put down the complicated manual in his hand, and then picked up a piece of paper glued to a computer the size of a suitcase.

The first one tells him how to operate a drone.

The second one tells them how to mount the configured remedial and missiles for the drone, and strongly recommends that he try the delivery process of the remedial before actually flying.

The third one told him how to change fuel cells for drones.

The illustrated explanation, like a game-like process, allows Li Tuo, a drone novice, to easily operate it for simple flight use.

The best thing is that its take-off and landing procedures have been set, and the only thing Li Tuo has to do is to clear the runway, and then plug beacons on both sides of the runway, so that the drone can automatically identify the location of the runway when it lands.

Li Tuo, who gave up pondering the drone, shrugged his shoulders at Tie Shu, then stood up and took out five retinators disguised as rocks, and mounted them on the wings and belly of the drone according to the operation on the manual.

Seeing Shang Fengzi looking at himself pitifully with a rocket, Li Tuo smiled and said, "Oh, no, no, we don't need them for the time being."

Test fly one first, and when the golden cicada and they start to act, we will arm one alone for you to play with.

Anyway, the military pays the bill, and when the time comes, we will put a cannon on it and try it, this thing can't kill anything in one shot, so don't waste money. ”

Shang Fengzi put the missile about the same height as him back into the arms box with a little pity, and then looked at the two 23mm cannons next to him? said: "This thing doesn't look as powerful as this big guy." ”

Li Tuo turned on the computer and found the cast button? I pressed it and found that all 5 retinators fell off at once? He reluctantly stood up and went to hang up those re-primers? While saying to Shang Fengzi, "Senior Brother Shang, think about it? You can shoot 500 rounds with a cannon, and 2 cannons are 1000 rounds.

But you died with a missile, that is, 5 rounds? And we keep these missiles useful.

Is it too obvious that fire reconnaissance directly uses drones? How safe is it that we find a suspicious place, and then set up these missiles on the ground away from the suspicious location, and then use drones to guide the launch? ”

Shang Fengzi listened? Honestly nodded? Then he bent down and picked up a round rotatable cannon for a helicopter gunship, and looking at the complex mechanical structure inside, as well as those thick bullets, he thought for a moment and said, "You must give me one to play with!"

I've never fought from a far place! ”

After re-attaching the re-mount, Li Tuo nodded at Shang Fengzi and said, "No problem!"

This thing is like a game? Later, you can familiarize yourself with the operation of the drone with me, and at least you can recognize all those words.

Let's expand the scope of the investigation to the maximum? Once you've mapped the entire cave, it's time for you to make a difference.

In good conscience? The bullets in those cannons are so powerful that they can hit the target accurately? The power is not at all worse than that of a missile. ”

Shang Fengzi grinned and said, "I understand? It's the difference between divine thunder and flying swords.

As long as the divine thunder dodges quickly? Even if you are on the edge of an explosion, you can resist a single resistance, but if you are directly stabbed by a flying sword, it will be over. ”

Li Tuo wanted to explain that there was still a difference, but in the end he nodded and said with a smile: "That's pretty much what it means, you can try it yourself when the time comes." ”

Saying that, Li Tuo re-found the "Delivery" option on the computer, this time he didn't make a mistake, tried the control keys of each hook, and successfully threw down the retinator.

Li Tuo clapped his hands with satisfaction, installed the retinator again, and set the automatic operation program after the launch.

Looking at the curious Tie Shu, Li Tuo walked to a desk made of boulder next to him, and then sent her an invitation and said, "If Senior Sister Tie Shu is interested, let's take a look."

If the three of us can control three drones and divide them into three directions to reconnoitre, the efficiency may be a little higher. ”

Tie Shu walked to Li Tuo's side curiously, and she and Shang Fengzi watched Li Tuo press the button on the computer......

I saw that the propeller at the tail of the drone began to rotate, and then it didn't need any operation, and after slowly gliding, it flew lightly into the sky, flying out of the range covered by the "Qiankun Sneaking Flag".

The most economical speed of a drone is 400 kilometers per hour, but it can fly at an altitude of nine kilometers.

Li Tuo controlled the drone and quickly reached its ceiling, but this was still not the limit of the height of the cave.

Through the drone's envisioned lens, there is still a distance of about 10,000 meters above to reach a place shrouded in white mist, which may be the limit of the height of the cave.

The scene of the cave sky shot under the lens of the drone is very shocking, the sun rises and sets, the tide rises and falls, and the vast cave sky presents a thriving scene.

The sun here is certainly not the real sun, but it is also providing light and warmth to the earth.

There is also a moon here, and whenever the sun sets, a round ball with a shimmering light will appear in the sky, replacing the role of the moon, and even providing some monsters with the power of Taiyin.

This is a super cave with all five elements, earth, water, wind and fire, and a balance of yin and yang.

Li Tuo really couldn't imagine what kind of power could build such a place.

In the past, the Minshan Cave Heaven he entered was also incomparably vast, and the nine dragon-like mountains were winding and tangled, domineering and desolate, but compared with the Zhongshan Cave Heaven, there was a lack of natural carving and harmony.

After the shock, Li Tuo lowered the altitude of the drone and began to fly in a circle in the air with excellent visibility.

Pressed the scan button and connected a solid-state drive to the computer, and then Li Tuo looked at Shang Fengzi, who was itching, and he said with a smile: "Senior Brother Shang, let's try it, let's first scan the map of the places they passed by, and then explore the periphery." ”

Shang Fengzi looks like a rough man, but he seems to be extremely talented for this kind of thing.

The operation of the drone is not too complicated, and the various buttons are set to the mode of a fool's touch screen, except for the conversion of traditional and simplified characters, and the meaning of some words, which took him a little time.

This guy is a really smart person, and after half an hour, he can even start to control the drone and do some simple flight maneuvers, which is a little faster than Li Tuo can get started.

Li Tuo, who was completely relieved after observing for a while, turned on the signal radar with a smile, and looked at the dense highlights on it representing the middle sequel, he smiled and pressed the communicator on the headset, and said, "Senior brother, how are you doing now?" ”

The senior brother didn't speak, but Jin Cicada was the first to reply and shouted, "What do you think we can do?" Running on two legs, you have to avoid those monsters.

Li Tuo, I haven't eaten for three days, you let us run around in a circle, is it okay now? ”

Li Tuo looked at the coverage of the remedial device on the radar, and he didn't believe that the golden cicada ran out on two legs.

Three groups of people have established a signal depth of 850 kilometers in three days, and if this is run out by legs, Li Tuo feels that his IQ can be dispensed with.

Hearing Jin Cicada's complaints, Li Tuo said with a smile: "It's almost enough, have you found anything?"

It's your job to mark the monster's habitat. ”

Jin Cicada replied proudly: "You definitely don't believe it, Senior Brother and I found a shape-shifting demon 'Spiral Turtle', that guy is bigger than the mountain, and his temper is not too bad."

I've left a mider on its back, so don't be surprised if you see it moving. ”

Li Tuo said in surprise: "What is the number of renewals?" I've got to mark it.

I'll go, the sphere of influence of the Shapeshifting Demon is a radius of 500 to 1,000 kilometers, this 'Spiral Turtle' is not good just by hearing the name, so as long as we take it easy, we are actually very safe? ”

As he spoke, Li Tuo noticed a blank space on the signal radar, which was about 600 kilometers away from his location, and he said strangely: "There is a small blank space in Area 6, what's wrong there?" ”

"Yang Jin led people to set up an ambush there, and now he is fighting fiercely with the big demon."

Li Yingqiong's voice came out of the communicator, and she said a little unhappily: "These people don't have the slightest idea of going deep, they want to strangle the big demon in this direction because of the large number of people." ”

Li Tuo playfully smashed his mouth and said with a smile: "These people are very smart, this is to force us to advance outward and find 'prey'."

Shouldn't we tell them they've won?

You say that we are so selfless, will it make these guys ashamed for a few seconds? ”

Jin Cicada sneered and said: "You can try, it's not that I live the belly of a gentleman with the heart of a villain, you tell them that we give up, those guys will only think you are playing tricks." ”

When a few people were talking, Shang Fengzi suddenly put on headphones, cut into the public channel not very skillfully, and said: "I saw them, wow, the fight is too fierce, 15 big demons are attacking a big array." ”
