I have a magical world.

The drone roared high into the sky along the relatively flat temporary runway.

The swirling airflow caused the ground to fly sand and rocks.

The slender fuselage soars into the sky nimbly, showing great maneuverability.

The Rainbow-3 UAV is codenamed CH-3 UAV.

It was independently developed by the Aerospace Aerodynamic Technology Research Institute of the Eleventh Research Institute of the Aerospace Science and Technology Group Corporation, now Aerospace Rainbow Company.

It is an unmanned aerial vehicle controlled by radio remote control equipment or its own program control device.

As a medium-range UAV system, its main equipment includes: UAV body, ground telemetry and remote control station and ground support equipment.

In addition, the Rainbow-3 UAV uses a piston engine, and its longest range can reach an astonishing 2400 kilometers.

The cruise time can be up to 12 hours, during which time no refueling is required.

The aircraft is equipped with high-precision ultra-wide-angle photography and video equipment and can be used as a sophisticated reconnaissance aircraft.

Utilizing its own aerodynamic stability and trajectory planning, the Rainbow-3 UAV can achieve low-altitude flight autonomously.

Generally speaking, in undulating mountainous areas, the general height of the Rainbow-3 drone is 100 meters above the ground, and the minimum height is 30 meters above the ground.

In addition to its military use, it is also used for prospecting through aeromagnetic sensors.

In total, Rainbow-3 has completed more than 5 kilometers of survey line production operations for the geological department.

It is worth mentioning that in the past, general aviation aircraft or small transport aircraft were mostly used in aerial geophysical exploration. Pilots flying under low-altitude conditions for a long time are prone to fatigue and dangerous. The accuracy of the route is also affected by human factors, and it must be carried out during the day.

The Rainbow UAV can exactly make up for this shortcoming. It has high safety, high level of automation, and can be deployed day and night, making UAV aerial geophysical exploration normalized and greatly improving the efficiency of production operations.

Its practicality and reliability have long been proven in practical positions.

The foreign trade price of this drone is as high as several million dollars.

Yi Qinnong didn't have many in his hands.

After Chen Xuan asked him to leave three times, even after signing the contract, the guy still had a pained expression on his face.

Now it seems that it is indeed a bit famous.

And this Rainbow-3 drone is equipped with live ammunition.

Equipped with precision-guided bombs and two air-to-ground missiles.

The integrated detection and attack drone, as the name suggests, is a drone that integrates the two functions of reconnaissance and strike.

Continuous inspection and beating, continuous beating and inspection, the main thing is practical!

After the Rainbow-3 successfully took off, the picture was also transmitted to the transfer platform below.

The distance is still relatively close, so there is no picture delay.

The radio wave environment of Naroa Continent can be described as "clean".

There is no electromagnetic interference.

These make unmanned transmission more stable.

However, due to the lack of support from local base stations and Beidou, it is now unable to complete long-range operations.

Otherwise, theoretically, this Rainbow-3 can almost fly from Magtan City to Black Leaf Sentinel Point.

Of course, this is the limit for one way.

If you consider the round trip, you have to refuel at least once in the middle.

While Chen Xuan controlled Rainbow-3 to fly toward the canyon shrouded in fog, he stared at the screen and carefully observed any possible changes.

After all, that place is marked as [extremely dangerous].

I am afraid that even the previous four elemental magical lands of [Lava Lake], [Willow Forest], [Sirn], and [Silver Lake] combined are not as dangerous as this canyon.

The distance of five kilometers is nothing. Just one minute later, Rainbow-3 was close to its destination.

It cruises at an altitude of about 100 meters above the ground.

This height is not too safe, and Chen Xuan is also prepared for the drone to be damaged.

No matter what, as long as there is movement below, he will definitely be able to see some clues.

A safe distance of five kilometers should be sufficient.

Chen Xuan's main thing is stability.

Only send drones to investigate first, never risk yourself rashly.

Maintaining awe is also a basic operation, which can help Chen Xuan avoid possible dangerous situations.

Even though Chen boasted that he had plug-in capabilities, he still did not get carried away.

The power of timing comes from rules, and he already knows that some rule controllers can resist his timing.

Invincibility has no absolute, only relative.

If he forgets to be in awe, he can easily overturn suddenly in the swell.

Chen Xuan deeply agreed with this.

Focus on the footage fed back by the drone.

The ultra-high-definition wide-angle camera allows most details to be seen at a glance.

The mist billowing above the canyon is quite active and does not seem to be formed naturally.

But what surprised him was that even though the drone was conducting reconnaissance above the canyon, there was no abnormal movement below.

Logically speaking, it is an [extremely dangerous] place and you will be attacked if you get even slightly closer.

But the situation with the drone proved there was something more to the matter.

Thinking of this, Chen Xuan couldn't help but narrowed his eyes.

He did not rashly control the drone to attack the canyon below.

Instead, he boldly lowered his flight altitude.

He even flies under the mist, using the sweeping airflow to slowly blow it away.

This canyon is also a hundred meters deep and two to three kilometers wide.

It's basically equivalent to a mini basin.

The thick fog gradually dispersed after the drone boldly lowered its altitude.

At the same time, it also sent back images closer to the canyon's surface.

In the drifting mist, Chen Xuan vaguely saw the upper part of a huge, dilapidated stone tower.

The style of that stone tower is very rough, a bit like the Leaning Tower of Pisa in Blue Star.

But it’s not sloped, and it occupies an amazing amount of space.

In terms of size alone, it is at least ten times the size of the Eiffel Tower.

It's just that the appearance is relatively retro by Blue Star's standards, with an obvious medieval European style.

The main body of the stone tower is generally intact, but there are many gaps.

The surface is slightly mottled, without any fancy runes.

No matter from which angle you look at it, this stone tower is filled with a strange feeling.

Especially here is the location of mysterious ancient ruins and misty mountains full of puzzles.

The top of the stone tower in the canyon has obvious signs of fracture and damage.

It turns out that this is not the complete version of it.

A stone tower suddenly appeared in such a place, which is definitely a strange thing.

Just when Chen Xuan was planning to control the Rainbow-3 drone to continue lowering its altitude.

The picture returned by the drone suddenly started to shake.

This means that its flight was disturbed and there was some kind of strong air current around it.

The next moment, the canyon floor that could be vaguely seen in the picture suddenly burst open.
