Necromancer: Becoming a God from a Lord

In the back garden of the lord's castle, there were things covered by a layer of rainproof tarpaulin - this was the magical creation that the Eye of Illusion said could allow mortals to fly into the sky, and it was also the "giant soft ball" mentioned by the astrologer.

"It was still in the experimental stage, so it was not announced..." Harvey pointed helplessly, "You don't have to be so anxious at all. It's not too late to come after the finished product is made."

Arturo said with a somewhat embarrassed tone: "It's really because Mr. Eye of Illusion and his men aroused our curiosity. Lord, please forgive our recklessness and rudeness. We also want to see this incredible miracle creation as soon as possible."

"It's not a miracle, it's just a hot air balloon." Harvey raised his hand and asked the guards to lift the tarpaulin, revealing a pile of huge animal skins that were stacked in a somewhat disorderly manner.

"Uh... this, how can this be a pile of leather? Isn't it said to be a weird soft ball?" Sirius and Prall walked around the pile of animal skins, looking puzzled.

"It's like this when it's not inflated. Wait a moment and let the guards prepare in advance."

Harvey signaled to the guard captain Tommy, who immediately led several warriors forward with an excited expression and began to fiddle with the pile of animal skins.

When the first test was launched, Harvey asked Tommy and others to take the risk and try to ride it. Of course, he also asked Duncan to act as a first aid person in case of emergency landing. In case of an accident in the air, he could at least transform into a huge flying griffin to protect the test personnel who were launched and landed safely.

Soaring in the sky like a bird is the eternal dream of an intelligent race like humans who can only live on the earth. From hot air balloons to airships, from airplanes to spacecraft, Harvey had witnessed the great sacrifices made by humans for flying in their exploration and challenges in his previous life, and finally got what he wanted.

Although there are spellcasters in this magical world, flying is still a privilege for a very small number of high-level extraordinary people. Even those who stand at the top of extraordinary power cannot claim to conquer the sky freely. The magic consumed by casting flying spells is far more than any other type of spells. Shapeshifters like Duncan who can transform into flying birds at will also need to accurately calculate their magic consumption during the casting process to avoid accidentally falling from the sky.

The principle of hot air balloons is very simple, and the materials and techniques required for making them are not difficult. It only requires solving the source and continuous supply of gas fuel and suitable airbag materials.

In the absence of chemical industry to provide high-pressure gas storage containers, the use of magic energy instruments as combustion devices for heating air can provide a continuous supply of heat energy for balloons, which can perfectly replace the modern technology of filling high-pressure gas cylinders with hydrogen.

The material of the airbag is relatively simple. A kind of group-living magic beast that is a specialty of the northern wilderness - that is, a subspecies of the magic beast riding by the demon clan - magically grows two layers of animal skin inside and outside. The outer layer is as hard as armor, and the inner layer is flexible and thin. With the help of rubber fruit coating, it can be made into a perfect airtight airbag. It is not only highly waterproof and leak-proof, but also difficult to be destroyed even by a sharp knife.

The guards brought out a huge rattan basket from the shed next to them, and quickly connected it to the coated animal skin with several thick ropes. Then they took out a simple metal cylinder, poured a test tube-sized liquid magic energy into it from the top, and then pulled the start lever on the side of the cylinder. Soon, the top of the cylinder began to spit out steaming hot air.

The person in charge of the operation immediately stretched the bottom of the animal skin airbag and aligned the air outlet of the metal cylinder with it. Then he saw the airbag slowly swell up, and it really looked like what the astrologer lady described - a huge, soft ball.

In order to be able to carry at least three people at the same time, Harvey, Chris, Benoit and other alchemists conducted repeated experiments several times before finally setting the size of the airbag to a standard of six meters in diameter at the widest point. Just to sew this huge animal skin airbag, the inner leather of twenty monsters was used up. In addition, the repeated spraying and drying of the rubber fruit coating took more than half a month to make this seemingly simple flying vehicle in front of us.

"Without the caster himself driving the magic power... just relying on this, this alchemical cylinder that sprays hot air, can make this big soft ball fly?" The three necromancers of the Academy of Sciences looked at each other and asked Harvey with some doubts.

Harvey sighed, hesitated for a while, and then explained: "Yes, hot air rises and cold air sinks... This is a very common natural phenomenon. As research-based spellcasters... We should have observed this simple common sense that contains the operating principles of all things."

Arturo's tone was a little confused, and he murmured: "Natural phenomena... simple common sense... contain the operating principles of all things. Shouldn't research-based spellcasters always observe the generation and operation rules of magic power? Why do we need to understand hot and cold air?"

Harvey shook his head helplessly, closed his mouth and said no more. It is probably a long way to go to let these self-proclaimed extraordinary spellcasters come into contact with modern scientific enlightenment knowledge... It is better to start from the baby and change the public imperceptibly in the popularization of basic education.

As a result, amid the bewildered expressions of a group of high-level spellcasters, the animal skin airbag finally fully inflated and slowly floated upwards. The traction rope that had been put on in advance also gradually straightened. Four or five soldiers hurriedly stepped forward and pulled it hard to control it, thus preventing it from letting itself go and flying into the air with the huge wicker basket.

"Wow! Really... it's really flying!"

Harvey raised his hand to make an invitation gesture, and said with a smile: "This half-finished hot air balloon can only carry three people at most. Dean Arturo's alchemical body is too heavy, so it is not recommended to try to ride it. The rest of you can take turns to try it."

Before he finished speaking, Elder Sirius and Councillor Prall climbed in with their hands and feet - they were typical research-type spellcasters, and the magic patterns in their bodies had not been successfully engraved with the flying spell, so they were most looking forward to experiencing the taste of flying.

Then the Eye of Illusion also turned over and entered the basket, smiling and saying: "Although I know the flying spell, I also want to try this way of flying that does not consume my own magic power, and I can also protect my two fellow mages when necessary."

With a slight shake, the guards who had tightened the fixed ropes loosened their hands, and the hot air balloon slowly left the ground with the huge hanging basket below, gradually climbing upwards, and soon passed the towering spire of the lord's castle.

No mistakes, just one post, one content, one book, one forum, one 6, one 9!

The people on the ground squinted their eyes and could clearly see the three people in the hanging basket looking down, their expressions excited and excited.

"Oh no!" Harvey slapped his head, "I forgot to teach them how to control the alchemical heating device, Mr. Duncan..."

Duncan nodded helplessly, and the metal prostheses on his body made a violent friction sound with his bones and flesh, and quickly turned into a huge flying griffin, soaring into the air and chasing after the hot air balloon that was flying higher and higher.
