The correct way to open the sprite

Use a trailer to drag 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 sandbox of the heavenly plane with the gate of the plane as the center point in a short period of time.

Cromwell couldn't help but be filled with emotion when he looked at the sand table with precise proportions, where even the depth of the ravine and the height of the hill were marked, and when he looked at the accurately marked chariot route and artillery firing points on the sand table.

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

Compared with the sand table used for surveying and mapping by the Cattail City Iron Army, that kind of map looked like a child's scribbling, rather than a battle 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 forces. How could this not make Cromwell feel ashamed.

The Master made up his mind and told Feng Yu that he would build a sandbox like this when he returned to Moran, but his motivation was extinguished by Feng Yu's words.

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

Feng Yu pointed to the sand table and said: "Let's not talk about anything else, just the straight-line distance and horizontal height. If one data is wrong, the artillery fighting outside the visual range may app download address xbzs be able to pour the artillery shells onto the heads of friendly troops.

You know, whether it is a soldier or a tank, when they call for support, they are not far away from the impact point of the shell. "

After Feng Yu finished speaking, he thought for a while and said, "But you can definitely build one. Anyway, you don't have the need for precise attacks.

Haven't you done it before? Haven't you seen the sand table in our Cattail City, and there are no flying units in the demon world. Your airships are flying around every day, so it shouldn't be difficult to make this thing."

Cromwell's old face turned red when Feng Yu asked him: "Didn't you think of it before? If I had known that this thing was so useful, I would have had it made 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 have found records about the existence of humanoid intelligent creatures in the heavens through ancient books of dragons and elves.

Moreover, they do not believe that the magic circle that blocks the loss of elements in the heavenly plane is made by wild beasts or uncivilized one-eyed trolls.

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

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

There is also the sky in 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 into the sky.

On the other hand, looking at the way those flying birds are able to fly at extreme heights, it doesn't seem like they are limited by their physical fitness.

According to this speculation, the gorgeous sky in the heaven is very likely to contain unknown dangers, which has made these birds living in the heaven form a habit, making them afraid to rise to a certain height limit.

According to the memories of the pilots who participated in the battle, the birds in the heavens only flew up to about 5000 meters and would not fly high at all. Even if the Tiejun fighter jets dived 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 as high as 5000 meters. You must know that the whooper swans on the earth can fly to a height of 8000 meters, and there is a big bird called the black and white vulture that can even fly Flying eleven thousand high in the sky.

Instead of blindly letting the fighter pilots take off, Feng Yu 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 heaven, there is a very dangerous sky. When the test balloons flew to about 5000 meters, they were destroyed for unknown reasons.

This discovery also frightened the fighter pilots of the Iron Army. However, this discovery allowed them to take off, although it was stipulated that they could only move within an altitude of 3000 meters in the heaven.

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

You must know that if you parachute in the heaven, as long as you land outside the iron army's control area, it will basically become food for the barbaric creatures in the heaven.

Therefore, the pilots were very obedient and tried not to fight with the flying creatures in the sky. They only relied on speed to get rid of them and conduct 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 revealed some amazing things. For example, the creatures near the gate of the celestial plane are not the densest place of celestial creatures. In the direction facing the gate of the plane, there are more and more celestial creatures, and they are denser. The degree is much higher than near the plane gate.

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

The reconnaissance plane exploring in the direction facing the gate of the plane has exceeded this distance, but did not find the boundary of the celestial plane. On the contrary, the celestial creatures there became more dense.

“Through our investigation near the plane gate, we found that these low-intelligent beasts in the heavens were not driven into the wilderness, but more like a spontaneous hunting behavior.

After the closure of the Lengshui River, the greening project of the Great Wasteland was launched. As the vegetation in the Great Wasteland increased, the number of animals in the wasteland and the livestock grazed by herders also continued to increase.

According to our investigation, when the plane gate was just opened, there was a herdsman grazing here with his livestock.

After those livestock were bitten to death by an animal that ran out of the plane gate and dragged into 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 later led to a large number of nearby celestial creatures entering the wilderness.

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

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