Chapter 117 Another Magic Application

"However, this kind of weak wind spell has another advantage, that is, it consumes less energy. After all, it is a spell that even apprentices of wind magic can cast.

Therefore, under the airbag of the goblin airship, there is a magic circle of the gust of wind inlaid, driven by the magic crystal, and the gust of wind will be used against the airbag every short period of time. "

Feng Yu said: "So the gas in the airbag is the wind element, or is it the gust of wind that changes the wind element?"

Clarence nodded and said, "That's right, there is the wind blow released by the magic circle of the wind blow, which is a form of wind element."

"But..." Feng Yu still didn't understand?

Clarence said: "It's really difficult for me to explain this problem to you when I have no knowledge of buoyancy and atmospheric pressure.

Spells formed by magical elements should be said to be weightless, and they move only when they are pulled by the magician's spiritual force.

Otherwise, do you think that for a forbidden curse of the level of Meteor Fire Fall, the spiritual power of a magician can really affect a meteor? "

Feng Yu said in surprise: "No weight?"

"That's right! Otherwise, the wooden spear technique of the plant system is not bad, but if the magical rock spear of the earth system of the same level is condensed, it cannot support its weight due to mental strength..."

Feng Yu imagined that Nidia condensed the rock spear, and then fell to the ground with a thud before it was shot... It was really embarrassing!

Clarence said: "According to what you said, the magical element is also a kind of energy, so it is easy to understand that it has no weight.

It is precisely because of this that the magic launched by the magician with spiritual power can be much farther than the spear thrown by the warrior. The senior mage can shoot the magic more than one mile away, and the magician can shoot the magic two miles away.

You must know that mental power has very little effect on real matter. Even we magisters can hardly move larger objects with pure mental power.

It is said that the spiritual power of the holy level has undergone transformation and can directly act on large objects, but you know how difficult it is to produce a holy level mage. "

The magician released by the magic element through spiritual power has no weight, because they are not matter, but a form of energy. Feng Yu figured out this theory after a little thought.

But that doesn't mean he doesn't admire the idea of ​​the goblin airship airbag.

There is a conjecture on the earth, that is, if a very light and high-strength compressive material is found, and the airbag of the airship is made of it, then there is no need to inject light gas into the interior, because no matter how light the gas is, , also has weight.

As long as the airbag made of this material can withstand the atmospheric pressure, it can do the opposite, extract the air in the motorboat, and turn the airbag of the motorboat into a vacuum bag. This is the idea of ​​the vacuum airship airship.

Don't underestimate this idea, because once this idea is realized, in theory, human beings can send objects beyond the upper atmosphere by relying on a sufficiently large vacuum motorboat.

In other words, aerospace aircraft carriers may become a reality.

It is also possible to use a vacuum airship to build a multi-level lifting platform in the outer atmosphere, so that the space elevator can greatly reduce the tension that the traction rope needs to bear by means of multi-layer borrowing.

And then there's things like stratospheric solar panels.

But any equipment that needs to float in the air for a long time can be realized by vacuum airship.

Compared with aviation kerosene and high-energy aerospace fuel, the cost of vacuuming is so cheap that human beings want to cry.

Therefore, if the space dream of human beings wants to achieve leapfrog development, a vacuum airship with a very cheap take-off cost is a good choice, but somehow, human beings do not have the material that is supposed to be light and able to withstand atmospheric pressure.

But what did Feng Yu see here today?
Goblins rely on filling the airbag of the airship with weightless magic gas, relying on the magic gas to prop up the airbag to resist atmospheric pressure, and using ordinary materials to complete the concept of human vacuum airship.

This is no longer enough to explain the shock in Feng Yu's heart with just a word of praise. He really wants to shout out a word of magic civilization at this moment, using the way of breaking the sound.

Immediately afterwards, Feng Yu was very melancholy. Humanity's low-cost space dream was actually used by a group of green-skinned dwarfs as a means of transportation.

Feng Yu asked: "Why aren't goblin airships used for war?"

This is a topic he is more concerned about. After all, this thing may be a threat to the Cattail City camp.

Clarence said: "Because it is not suitable. What is it used for, transporting soldiers? The volume is too small, and a dozen soldiers will not be of much use."

Feng Yu said: "High-altitude investigation, the enemy's movements are clear at a glance, how awesome!"

Clarence said with a smile: "Survey is only a reconnaissance if you can bring the information back alive. The goblin airship is so slow, and a wizard at the mentor level can easily shoot it down.

Such expensive things are not used in small wars, and how can there be no army magicians in large wars? ! "

Feng Yu nodded, it turned out to be the case.

But he changed his mind and said: "It can be used to transport magicians. Magicians are a strategic force. Can transporting magicians play a decisive role?"

"It's still the same problem, the goblin airship is big and slow, it's not easy to maneuver and it's easy to be spotted.

Besides, magicians at the magister level can only be called strategic power because they can use large-scale magic, but all magicians at the magister level can fly by using spells such as levitation or scrolls.

With the war together, who cares about the consumption of magic scrolls or magic crystals, just let the magician fly forward quickly and covertly.

Even a little more extravagant, you can use the teleportation circle.

As for the low-level magicians who can't fly, they are not enough for strategic power, and it is useless to transport them by goblin airships. The larger the scale of the war, the less useful they are.

As for simply using it as a means of transportation, those wealthy human nobles can indeed do it, but they seem to prefer to drive mounts, because it is better to be safe. After all, once the goblin airship has an accident in the air...you know.

The lives of nobles are precious, so they would not take such a risk.

Therefore, except for goblins, few people use goblin airships. Even goblins use the most frugal airship design to reduce the cost of use.

You'll know after a while when they land, riding a goblin airship is not a good experience. "

Feng Yu froze for a moment, and hurriedly found someone to arrange the landing of the goblin airship. After all, it was impossible for them to land in the camp area, and confidentiality and privacy were not counted. Feng Yu was afraid that this thing would crash.
