Steel, Guns, and the Industrial Party that Traveled to Another World

There is a magical magic that can make the recipient float for a short time more than ten meters high, so it is named levitation, but its magical degree has not yet developed to the extent that people can really break free from the constraints of the earth. It is more like an enhanced version of "high jump".

The hot air balloon that Mariana and Nathan took today has a conservative estimate of a rise of seven or eight hundred meters.

They took a hot air balloon to travel in the sky. When they landed, they were still immersed in the excitement of touching the sky for the first time in their lives. Looking down at the world from a high altitude, the scenery below is dotted with forests, lakes, villages, and towns. This novel experience is something they have never had in their lives before.

When they came down from the basket, Mariana praised the hot air balloon, and although Nathan could not hide his excitement between his eyebrows, he also gave birth to some uneasiness in his heart.

He used to be proud of magic, because magic can do things that mortals can't do anyway, but today's high-altitude trip has a great impact on the beliefs he has always held.

How do spellcasters understand magic? Throughout the long history, wizards have summed up some "rules", which are those difficult notes, complex patterns or gestures, and wizards use them to project mysterious power from the spiritual world into reality.

However, these "rules" cannot be connected with the effects presented by magic through the known logic in reality, or cannot be deduced step by step.

Just like the sun will come out after the rooster crows.

In the long run, spellcasters have to face the reality: magic is a mysterious existence that is not bound by the logic of reality and cannot be explored in its origin.

When in the sky, Nathan listened to the experimenter Aubrey's explanation of the principle of hot air balloons again. He said that matter is composed of elementary particles that are invisible to the naked eye, he talked about thermal expansion and contraction, and he talked about the buoyancy formula.

Some Nathan could understand, and some he couldn't understand, but from Aubrey's relaxed and calm eyes, it is obvious that this hot air balloon does not involve any mysterious factors that cannot be explored in essence, and its flying principle depends entirely on the law of nature.

Mortals have done what magic cannot do.

If the hot air balloon was invented by one or a group of spellcasters, Nathan might feel better, but this hot air balloon is really a miracle created by mortal hands and the laws of nature.

After Marianna and Nathan finished their high-altitude journey, Catherine also strongly requested to ride it once.

A girl can be so brave, as a man, Paul has to go for the sake of face. He overcame his fear of heights and walked into the guardrail with a little stiff legs.

Marianna also asked to go with them again for their safety. She still had doubts about the reliability of the hot air balloon.

The third launch of the hot air balloon took a while. Because it needed to be refueled, Paul asked the guards to buy some wool from the surrounding villages and towns as fuel, which was enough to support it to take off again.

After the launch, Catherine stood there stiffly, holding the cable tightly with both hands, and her tightly closed red lips showed her inner tension. The impact of the high altitude obviously exceeded her psychological preparation in advance.

In the princess's past life, she had also climbed mountains. She had overlooked the abyss from the cliffs. She thought she was not afraid of heights, but what she overlooked was that even if she stood on the cliffs, she was still down to earth, not like now, with nothing to rely on.

When she thought that there was a thin layer of wood under her feet and only hundreds of meters of air below, Catherine was tightly gripped by an indescribable fear.

It is puzzling that when a woman becomes timid, especially a beautiful woman becomes timid, the man around her will automatically become bolder. Seeing Catherine like this, Paul took a deep breath and took her into his arms. The discomfort caused by fear of heights disappeared, and was replaced by a warm and soft feeling of comfort.

"Trust our technicians!"

His relaxed and confident tone made Catherine feel much more at ease. Although she was still nervous, she gradually adapted to it.

After being freed from fear, Catherine turned her attention to the hot air balloon itself. As expected, the scenery below was unobstructed. Catherine imagined that she was on the battlefield. The enemy's military deployment and mobilization would be no secret to her. Even if the enemy reinforcements approached from a distance, she might notice it earlier than the commander on the opposite side.

The research on hot air balloons has a very realistic demand factor for the Alda army.

Paul's idea of ​​the war against the orcs is not limited to the territory of Ordo. After expelling the orcs from the country, Ordo must completely solve the threat to its north. In the vast grassland and the desolate Gobi, they may become the scenes of the battle between the Austrian army and the orcs.

In such an open area, it is very beneficial to have an observation point located at a high altitude to judge the battlefield situation. Especially for the high-speed and erratic orc cavalry, with the cooperation of telescopes and flag signals, hot air balloons can play a good early warning role.

The thrilling high-altitude journey ended, but it was an unexpected episode. The next day, Paul invited Catherine and a group of royal army generals to visit the cannon foundry as planned.

Arda's cannon-casting technology has just been upgraded, the most important of which is the introduction of boring technology or boring machines.

On Earth, John Wilkinson invented the boring machine in 1774. Its original purpose was to make more accurate artillery, but it unexpectedly played a key role in the manufacture of steam engines.

But in this world, the application of boring machines has undergone a reverse process.

No mistakes in one poem, one post, one content, one 6, one 9, one book, one bar!

Inspired by Paul, Burns has been studying steam engines. The biggest challenge he faces is that the inner wall of the hand-cast cylinder is rough and uneven, resulting in a large gap between the piston and the cylinder, serious steam leakage, and low thermal efficiency.

So he needs a processing tool that can process the inner wall of the cylinder very smoothly and accurately to greatly reduce steam leakage. After hard research and long experiments, the boring machine in this world came into being.

Under the chairmanship of Paul, the various production and manufacturing departments of Alda will hold technical exchange meetings regularly, and the boring machine is also introduced to the heads of other departments by Burns.

The military industry department immediately realized that this tool could play a revolutionary role in the production of artillery.

The traditional hand-cast cannons have the same problems as Burns faced when studying the cylinders. The inner wall is rough and uneven, and the gas leaks seriously when the gunpowder burns, resulting in low initial velocity and short range of the shells. In addition, the uneven stress of the inner wall can easily cause the barrel to explode.

Although the craftsmen have been striving for excellence under strict requirements, the precision that can be achieved by hand is ultimately limited.

The emergence of boring machines changed this situation. It was soon introduced into the cannon casting work, and took this opportunity to significantly upgrade the entire cannon casting process.

Sorry, I went back to my hometown yesterday and had a lot of things to do. I went to bed early at night, so this chapter was posted late.
