The correct way to open the elf

Chapter 452 Dangerous Sky

Use a trailer to tow the plane that landed outside the plane gate into the runway inside the plane gate, and the plane can take off in the heavenly plane.

What surprised Cromwell even more was that the Iron Army's reconnaissance team actually built a terrain sand table of the heavenly plane with the Plane Gate as the center point in a short period of time.

Looking at the sand table with precise proportions, where even the depth of gullies and height of hills were marked, and the precise markings on the sand table on which the chariot's marching routes and artillery firing elements were placed, Cromwell could not help but feel deeply moved.

They, Moran, have been fighting the demon world on their own territory for so long, but they are still relying on the old map.

Compared with the sand table surveyed by the Pupu City Iron Army, that kind of map is just like a child's doodle, rather than a battle map for the frontline soldiers.

On the other hand, the Cattail City Iron Army could apply for artillery support at a certain coordinate from an invisible position on the front line, and the artillery could launch an attack in minutes without worrying about accidentally injuring friendly forces. How could Cromwell not feel ashamed of this?

The Master of Magic made up his mind and told Feng Yu that he would also build such a sand table when he returned to Moran, but Feng Yu's words extinguished his enthusiasm.

"Do you really think this is easy? Without professional surveying talents and equipment, do you want soldiers to measure distances by footsteps and mountain heights by height?"

Feng Yu pointed at the sand table and said, "Let's not talk about anything else, just the straight-line distance and horizontal height. If one of the data is wrong, the artillery fighting outside the visual range may pour shells on the friendly forces.

You know, whether it's soldiers or tanks, when they called for support, they were not far away from the impact area of ​​the shells. "

Feng Yu thought for a moment and said, "But you can certainly make one, since you don't have the need for precise attacks anyway.

Haven't you done it before? Haven't you seen our Cattail City sand table? Besides, the creatures in the demon world don't have many flying units. Your airships fly in the sky every day. It shouldn't be difficult to make this thing, right?"

Cromwell blushed when Feng Yu asked him this: "Before... I didn't think of it! If I knew this thing was so useful, I would have asked someone to make it long ago. We in Moran also have many skilled craftsmen."

Feng Yu spread his hands: "As long as you are happy."

Both Feng Yu and Cromwell had found records about the existence of humanoid intelligent creatures in heaven through ancient books of dragons and elves.

Moreover, they also did not believe that the magic circle that blocked the loss of elements in the heavenly plane was created by those beasts or uncivilized Cyclops.

Although the Cyclops in the celestial realm had a primitive social structure, they had no wisdom inheritance or knowledge learning system, so it was absolutely impossible for them to not have the ability to set up such a complex and large magic array.

So no matter what the reason is that the intelligent life in the heavenly plane did not appear in the plane war, they are all potential dangerous factors.

There is also the sky of heaven. In previous air battles, the fighter pilots of Cattail City had discovered that the large carnivorous birds in heaven did not dare to fly too high.

On the other hand, the birds seem to be able to fly with ease at "extreme" altitudes, and it doesn't seem like they are limited by their physical fitness.

According to this speculation, there are very likely unknown dangers in the magnificent sky of heaven, which have caused the birds living in heaven to form habits and make them dare not rise to a certain height limit.

According to the recollections of the pilots who participated in the battle, those birds in the heavens could only fly to a maximum of about five thousand meters and would not fly higher at all. Even if the Iron Army's fighter planes dived to attack them from high altitude, they would not fly higher.

But it is obviously impossible for a big bird that dares to attack propeller fighters to fly only 5,000 meters high. You should know that the swans on Earth can fly to an altitude of 8,000 meters, and there is a big bird called the black and white vulture that can fly to an altitude of 11,000 meters.

Feng Yu did not blindly let the fighter pilots take off. Instead, he conducted a large number of tests on the sky of heaven with hydrogen balloons and finally discovered the secret of the sky of heaven.

Although the heaven is called the heaven, it has a very dangerous sky. When the test balloon flew to about 5,000 meters, it was destroyed due to unknown reasons.

This discovery also frightened the Iron Army's fighter pilots, but it allowed them to take off, although they were stipulated to only operate within an altitude of 3,000 meters when in the heavens.

However, for safety reasons, fighter jets were kept outside the control of the Cattail City Iron Army and were prohibited from fighting with aerial creatures in the heavens to avoid aircraft malfunctions.

You have to know that if you parachute in the heaven, as long as you land outside the Iron Army's control area, you will basically become food for those savage creatures in the heaven.

Therefore, the pilots were very obedient and tried their best not to engage in aerial dogfights with those flying creatures in the sky. They just relied on speed to get rid of them and conduct reconnaissance operations.

The launch of fighter jets and reconnaissance planes also greatly accelerated Xiangpu City's progress in exploring the heavens.

This measurement also revealed some remarkable things. For example, the creatures near the gate to the heavenly plane are not the most densely populated place. In the direction facing the gate to the plane, there are more and more heavenly creatures, and the density is much higher than near the gate to the plane.

Moreover, the gate to the heavenly plane is not opened in the center of the plane, because when the pilots were exploring near the gate, they found that the boundary of the heavenly plane was discovered within a distance of less than a thousand miles in the direction opposite to the gate.

The reconnaissance aircraft exploring in the direction of the plane gate has exceeded this distance, but has not found the boundary of the heavenly plane. Instead, the celestial creatures there are even more densely populated.

“Through our investigation near the Plane Gate, we found that these beasts from the heavens with low intelligence were not driven into the Great Wasteland. Instead, it was more like a spontaneous hunting behavior.

After the Lengshui River was dammed, the greening project of the Great Wilderness was launched. With the increase of vegetation in the Great Wilderness, the number of animals on the wilderness and the livestock grazing by herdsmen also continued to increase.

According to our investigation, when the plane door was just opened, there was a shepherd grazing his livestock nearby.

After those livestock were bitten to death and dragged into the plane gate by another livestock that ran out of the plane gate, a large number of celestial creatures entered the wilderness to hunt.

It may be that the smell of blood stimulated more celestial creatures, which led to a large number of celestial creatures nearby entering the wilderness.

However, according to our investigation, we found that these celestial creatures that invaded the Great Wasteland originally lived near the Plane Gate.

We also found the lair of the Cyclops tribe, and the Iron Army soldiers even captured a few little Cyclops alive. ""
