We are in Terra and there is no book to read.

The First Branch of the Aircraft Factory is responsible for the design, production, and maintenance of aircraft.Aircraft imported from Yanguo and Colombia will return here regularly for maintenance.In addition, there is also a dedicated gas source stone processing workshop here to export cheap airship filling gas to countries such as Ursus and Colombia that use airships on a large scale.

The Second Branch is responsible for the development and production of helicopters, and even pilot training is conducted here.So far, Kazdale has accumulated 18 helicopter pilots and 36 student pilots with several years of flying experience.

Although the Skylark helicopter has not been significantly modified, subtle adjustments have not been interrupted. From the perspective of its role as a technical experiment and teaching platform, the Skylark has been very perfect.The two pilots flew the helicopter respectively and performed takeoff, rough hovering, and landing for the Wangting team leaders.

The patriarchs, who were several hundred years old on average, and the college graduates, who were in their 20s on average, had expressions of surprise on their faces.The Blood Demon Lord is a little better, because just a few days ago, several juniors in the clan told him about this stuff.The Patriarch of the Absolution Division and Mel designed the multi-rotor drone together. Although he was not responsible for the aircraft part, he was quite curious.

"It only has one lifting propeller, how does it move forward?"

"Similar to multi-rotor drones, horizontal movement is achieved through lift difference."

Zeppelin pointed to the helicopter on the tarmac nearby and explained: "If the helicopter needs to fly forward, then each blade will change its shape and create more lift when it rotates to the rear of the helicopter, allowing the helicopter to fly forward." The fuselage tilts forward and moves."

The leader of the Pardoner nodded, this is quite understandable.

"I don't see anything armed. Is it unarmed?"

"Not yet. The Skylark helicopter moves at a speed of 150 kilometers per hour. The pilot currently thinks the appropriate height is 300 meters. We have tested the installation of a semi-automatic individual crossbow in this situation, but the result was that the arrows scattered randomly in the air. It’s not accurate at all.”

Zeppelin shook his head, "We have also tried attack-type spells, but even if they are sealed in the Source Stone crystal and released, they can achieve higher stability. The effective range of the spell is also about 80 meters. If it exceeds this range, the spell will be constructed The shape will gradually lose stability, and then cause the magic energy to dissipate. It is estimated that it will take some time for Skylark to be officially used."

Factory No. [-], this is one of the places with the highest level of security in Kazdaele currently. It is responsible for the production and use of new layout aircraft. The training of piercing drones and piston aircraft is also carried out here.

A large number of metal poles are inserted in the open space, with round or square collars fixed on them. The operators of the puncture drones need to fly the training drones to continuously improve their skills.

In order to cooperate with the training, the Impaler drone was specially modified for training. The explosive part was replaced with a counterweight, and landing gear was also installed.

In the venue, the Impaler drone quickly shuttled between the rings along a fixed route. The speed made the banshee feel surprised.

"It's so strange. How come the propeller is right in front of you...how fast is this flying?"

"The speed is 180 kilometers per hour. The fastest speed of Terra's mainstream drones is 70 kilometers per hour. When we attacked the Victoria artillery position, Victoria's drone tried to intercept us, but it had no effect."

Zeppelin's introduction aroused the exclamation of all the students. They excitedly surrounded the weapon master and looked at the screen of his instrument curiously.

To be honest, the clan leaders were actually a little curious. This was the first time they had seen something so fast.But as they consider themselves elders, they won’t crowd around like children...

Teresica saw that all the clan leaders seemed to be distracted, except that the Banshee clan leader was inexplicably raised a step higher.After glancing at it from a distance, it descended silently, as if nothing happened.

In the sky, harsh sounds came from far away. Everyone looked together and found a shadow in the sky that was about the same size as a helicopter, passing over their heads at high speed.

"What is this? It's too fast!"

The clan leaders were really shocked today, even the Blood Demon Lord was no exception. His blood attack couldn't keep up with an object of this speed.

"The single-cabin biplane adopts the same layout as the Impaler drone and is the original technology demonstrator. The speed reached 280 kilometers per hour."

Zeppelin raised his head and said: "It still has a lot of room for improvement, and its speed is definitely not what it is now."

The patriarchs all stared at the shadow, with expressions of surprise that could not be concealed on their faces. Has the war become like this?

Kazdel's first piston aircraft was constantly circling around. Suddenly, a puff of black smoke came out of its body, and the aircraft suddenly fell sideways.
