Chapter 452 The Dangerous Sky

Use a trailer to drag the plane that landed outside the gate of the plane into the runway inside the gate of the plane, and the plane can take off on the plane of heaven.

What surprised Cromwell even more was that the Iron Army's reconnaissance team actually built a topographic sand table on the celestial plane with the gate of the plane as the center in a short period of time.

Looking at the sand table with precise proportions, even the depth of the ravine and the height of the hills, and the precise marking of the chariot line and artillery shooting on the sand table, Cromwell couldn't help but feel a lot of emotion.

They, Moran, have fought against the Demon Realm on their own territory for so long, yet they are still relying on the old old map.

Compared with the sand table surveyed and mapped by Cattail City Iron Army, that kind of map is like a child's scribbles, not a combat map for frontline soldiers.

On the other hand, the Cattail City Iron Army applied 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 fear of accidentally injuring friendly troops. How could this not make Cromwell feel ashamed.

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

"You really think this thing is easy to make. Without professional surveying and mapping talents and equipment, do you want soldiers to measure distance by steps and height of mountains by height?"

Feng Yu pointed to the sand table and said: "Not to mention anything else, just talk about the straight-line distance and horizontal height. If one data is wrong, the artillery fighting outside the visual range may pour shells on the heads of friendly troops.

You must know that whether it is a soldier or a tank, when they call for support, they are not far from the range of the shells. "

Feng Yu thought for a while and said: "But you can do one, anyway, you don't need precision attacks.

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

Cromwell blushed when asked by Feng Yu: "Before... didn't I think of it! I want to know that this thing is so easy to use, it has been made by someone long ago, and we Moran also have many skilled craftsmen."

Feng Yu spread out his hands: "Just as long as you're happy."

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

And they also don't believe that the magic array that prevents the loss of elements in the heavenly plane is made by those wild beasts or uncivilized one-eyed trolls.

Although the one-eyed trolls in the heavens have a primitive social structure, they have no wisdom inheritance and knowledge learning system, and it is absolutely impossible that they do not have the ability to set up such a complex and large magic circle.

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

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

On the other hand, the way those flying birds are able to do a job with ease at the 'extreme' height does not seem to be the reason for being limited by physical fitness.

According to this speculation, there is a high possibility that unknown dangers exist in the gorgeous sky of the heaven, which makes these flying birds living in the sky form a habit, so that they dare not rise to a certain height limit.

According to the memories of the pilots who participated in the battle, the birds in the sky only flew up to about 5000 meters, and they would not fly high at all. Even if the fighter jets of the Iron Army swooped down to attack them at high altitude, they would not fly higher.

But this kind of big bird that dares to attack propeller fighter jets obviously cannot fly at a height of 5000 meters. You must know that whooper swans on the earth can fly to a height of 8000 meters, and there is a big bird called black and white vulture. It can fly to a height of eleven thousand.

Feng Yu did not blindly let the pilots of the fighter jets go into the sky, but used hydrogen balloons to conduct a lot of tests on the sky of Tianjie, and finally discovered the secret of the sky of Tianjie.

Although the sky is called the sky, it has a very dangerous sky. When the test balloons flew to about 5000 meters, they were all destroyed due to unknown reasons.

This discovery also shocked the fighter pilots of the Iron Army, but with this discovery, they were able to take off into the air, although it was stipulated that they could only move within 3000 meters when they were in the sky.

However, for the sake of safety, the fighter planes are stipulated to be outside the control range of the Cattail City Iron Army, and it is forbidden to fight with the aerial creatures in the heavens to avoid the aircraft malfunctioning.

You must know that if you parachute in the sky, as long as it falls outside the control area of ​​the Iron Army, it will basically become food for those barbaric creatures in the sky.

So the pilots are very obedient, try not to fight with those flying creatures in the sky, and only rely on speed to get rid of them and carry out reconnaissance operations.

The launch of fighter jets and reconnaissance planes has also greatly accelerated the progress of Cattail City's detection of the heavens.

And this test also found some amazing things. For example, the creatures near the gate of the celestial plane are not the densest place for celestial creatures. In the direction that the gate of the plane faces, there are more and more celestial creatures, dense The degree is much higher than near the gate of the plane.

Moreover, the gate of the plane of heaven is not opened in the center of the plane, because when the pilots explored near the gate of the plane, they found that the direction facing away from the gate of the plane was less than a thousand miles away. , the boundary of the Celestial Plane has been discovered.

The reconnaissance plane exploring in the direction facing the gate of the plane has already exceeded this distance, but has not found the boundary of the celestial plane, but the celestial creatures there are more dense.

"Through our investigation near the gate of the plane, we found that these beasts with low intelligence in the heavens entered the wilderness not driven, but more like a spontaneous hunting behavior.

After the closure of the Lengshui River, the greening project of the Great Wasteland started. With the increase of the vegetation of the Great Wasteland, the number of animals and herdsmen's grazing livestock on the wasteland is also increasing.

According to our investigation, when the gate of the plane was just opened, there was a herder nearby with a herd of livestock grazing here.

After those livestock were killed by a livestock that ran out of the gate of the plane and dragged into the gate of the plane, 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 nearby celestial creatures entering the Great Wasteland.

However, according to our investigation, we found that these celestial creatures who invaded the Great Wasteland originally lived near the gate of the plane.

We also found the lair of the one-eyed troll tribe, and the soldiers of the Iron Army even captured a few small one-eyed trolls alive. ""
