The place where they are located is mountainous and the terrain is high, which has a natural advantage for the heavy industrial areas at the foot of the mountains.
Although a series of ultra-long attack range weapons such as the Dragon Flame Cannon are obviously insufficient at such a distance, they are unable to launch effective artillery strikes against the heavy industrial area at the foot of the mountain.
However, this does not mean that there is no way to attack the heavy industrial area at the foot of the mountain.
Liu Zheng remembered a book he read in his last life, which introduced the use and research of gliders.
This kind of glider, which is closely related to the kite invented in human history, had no so-called power device when it was first studied and invented.
The structure is also very crude.
It still needs human power to fly, and it is extremely unstable, and the distance it can fly is also very short.
After all, after the original glider prototype was produced, its only purpose was to send people into the sky and let them fly in the air, but this goal was successfully achieved.
It was only after the invention of the engine and a series of improvements that the airplane was officially invented.
However, the glider did not disappear from the stage of history.
Instead, it became an extreme challenge sport and survived. Liu Zheng once read about the manufacturing of gliders.
The manufacturing structure of a glider is not very difficult, what is difficult is the invention process.
This process requires constant trial and error in order to gain success through mistakes and maybe a little bit of experience, but for Liu Zheng, there is no need for such a complicated research process.
What is recorded in his mind are all success stories.
He just needs to let his scientific research team present these successful cases again.
Thinking of this, Liu Zheng immediately summoned the weapons manufacturing and research department of the Long Yan Army.
Long Yanjun experienced Liu Zheng's reforms.
Among his requirements, every Longyan Army must have a maintenance and research team.
Weapons used to maintain Dragon Flame and the possibility of discovering and exploring more combat weapons and equipment.
This army is no exception.
Soon, Liu Zheng summoned his troops and told them his thoughts.
"We need to drop attacks from the air and attack the heavy industrial areas of Saxony."
"But we can't fly, so do you have any good ideas about this matter?"
When everyone heard Liu Zheng's thoughts, the first thought in their minds was that Liu Zheng was talking nonsense, but the next thought was, no, if the person standing in front of them was someone else, they could think like this.
But it was Liu Zheng who proposed this idea!
He is the legend who single-handedly pushed Long Yan into a new era, Liu Zheng, Lord Liu, the chief assistant of the dynasty!
His ideas were too wild and unrealistic, but none of them were unrealized.
As the captain of the scientific research and maintenance team of this army, Wang Congyang thought for a while and said: "According to my understanding, in the history of Longyan, there were talented people and strangers who once invented a paper lantern to transmit messages."
"Some people also invented paper kites to deliver messages."
"But I have never heard that they can send people to heaven."
Liu Zheng nodded. The first thing Wang Congyang mentioned was the Kongming Lantern, which is launched using the principle of hot air rising. There is no hot air balloon invented yet.
Otherwise, Wang Congyang's words would definitely be slapped in the face.
The Kite is the original prototype of a glider. The two are inextricably linked, as they both use airflow to fly into the air.
