Chapter 117: Alternative Applications of Magic

“However, this weak Wind Spell has another advantage, which is that it consumes less energy. After all, it is a spell that even wind magic apprentices can cast.

Therefore, under the airbag of the goblin airship, there is a magic array of whirlwind magic embedded, which is driven by magic crystals and uses whirlwind magic on the airbag every once in a while."

Feng Yu said: "So the gas in the air bag is the wind element, or the wind element's transformed wind technique?"

Clarence nodded and said, "Yes, what's in there is the whirlwind magic released by the whirlwind magic circle, which is a manifestation of the wind element."

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

Clarence said: "It was hard to explain this to you before I learned about buoyancy and atmospheric pressure.

Spells formed by magic elements are, it can be said, weightless; they move under the pull of the magician's mental power.

Otherwise, do you think that a magician's mental power can really move a meteor with the level of Meteor Fire Falling Forbidden Spell? "

Feng Yu said in surprise: "No weight?"

"That's right! Otherwise, the plant-based wooden spear technique is fine, but if it is the same level of earth-based magic rock spear, it will be too heavy to support because of mental strength after it is condensed..."

Feng Yu imagined the scene where Nitia condensed the rock spear, and then it fell to the ground with a thud before it could be shot out... It was really embarrassing!

Clarence said, “According to what you said, magic element is also a kind of energy, so it is easy to understand why it has no weight.

It is precisely because of this that the magic cast by a magician using his mental power can reach much farther than a warrior's spear. A high-level wizard can shoot magic more than a mile away, and the range of a mage can reach two miles.

You know, mental power has very little effect on real matter. Even for us magicians, it is difficult to move large objects with pure mental power.

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

The magic elements released by the magician through mental power are weightless, because they are not matter, but a form of energy. Feng Yu understood this theory after a little thought.

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

There is a conjecture on Earth that if we find a very light, high-strength, pressure-resistant material and use it to make the airbag of an airship, then there is no need to inject light gas into the interior, because even the lightest gas has weight.

As long as the airbag made of this material can withstand the atmospheric pressure, we can do the opposite and pump out the air in the motorboat, turning the airbag of the motorboat into a vacuum bag. This is the concept of a vacuum airship.

Don't look down on this imaginative idea, because once it is realized, in theory, humans can use a large enough vacuum airship to send objects out of the upper atmosphere.

In other words, the aerospace aircraft carrier may become a reality.

It is also possible to use vacuum airships to build multi-level lifting platforms in the outer atmosphere, allowing the space elevator to greatly reduce the tension that the traction rope needs to bear through multi-layer leverage.

Then there are things like stratospheric solar panels.

Any equipment that needs to float in the air for a long time can be achieved by using a vacuum airship.

The cost of vacuuming is so cheap compared to aviation kerosene and high-energy aerospace fuel that it makes humans want to cry.

Therefore, if mankind's space dream is to achieve a leap forward, a vacuum airship with a very cheap take-off cost is a good choice. However, mankind does not have the material that is both light and able to withstand atmospheric pressure as envisioned.

But what did Feng Yu see here today?
The goblins filled the airbag of the airship with weightless magic gas, and used the magic gas to prop up the airbag to resist the atmospheric pressure, thus completing the human concept of a vacuum airship using ordinary materials.

This was no longer a simple word "awesome" to describe the shock in Feng Yu's heart. At this moment, he really wanted to shout "Magic civilization is awesome" in a way that made his voice crack.

Then, Feng Yu felt very melancholy again. The human beings' low-cost space dream was actually used as a freight vehicle by a group of green-skinned dwarfs. There were so many things he didn't know whether to say or not.

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

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

Clarence said, "Because it's not suitable. What can you use it for? Transport soldiers? The carrying capacity is too small. A dozen soldiers can't do much."

Feng Yu said: "High-altitude reconnaissance, the enemy's movements can be seen at a glance, how awesome!"

Clarence smiled and said, "Only reconnaissance can be considered reconnaissance if you can bring back intelligence alive, right? The goblin airship is so slow that any instructor-level magician can easily shoot it down.

Small wars don't require such expensive equipment, but how could a large war not have military magicians?!"

Feng Yu nodded. So that's how it is.

But he changed his mind and said, "It can be used to transport magicians. Magicians are strategic forces. Wouldn't transporting magicians play a decisive role?"

"It's the same problem. The goblin airship is large and slow, difficult to maneuver and easy to be discovered.

Besides, mage-level magicians can be called strategic forces because they can use large-scale magic, but mage-level magicians can all fly by relying on spells such as levitation or scrolls.

When a war breaks out, who cares about the consumption of magic scrolls or magic crystals? Just let the magician fly forward quickly and stealthily.

If you are even more extravagant, you can use a teleportation array.

As for the low-level magicians who cannot fly, they are not yet a strategic force, and it is of little use 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 driving mounts because they are safer. After all, if a goblin airship encounters an accident in the air... you know.

The lives of nobles are very precious, so they would not take such risks.

So apart from the goblins, few people use the goblin airship. Even the goblins use the most frugal airship design to reduce the cost of use.

You will know when they land in a moment, riding on a goblin airship is not a pleasant experience."

Feng Yu was stunned for a moment, and hurriedly asked someone to arrange for the goblin airship to land. After all, it was impossible for them to land in the camp area. Confidentiality and privacy were not taken into account, and Feng Yu was afraid that this thing would have an air crash.
