Yang Fugui kept walking in front of these planes. This was the first time that Yang Fugui observed the planes up close. "I heard that the planes were developed based on war instruments? It was this thing that protected the safety of the Shang Kingdom!"
Yang Fugui widened his eyes and observed carefully, and he actually had the idea of selling an airplane!
Suddenly, cheers came from behind, and someone said:
—The Grand Elder of Lingyun Sect chartered three Magic Eagle planes at once, for half a day.
—Doesn’t that cost more than three million taels of gold
—I heard that there was a discount, totaling 3.2 million taels of gold.
3.2 million taels of gold, just for fun? Yang Fugui turned around in a daze. He just happened to see Ning Chengzi and his group boarding the plane, which was sliding slowly.
…
Airplanes are expensive, but worth it!
Ning Chengzi, the supreme elder of Lingyun Sect, felt the power of the plane and was filled with emotion.
I had tried my best to fly to an altitude of 8,500 feet, and I had tried every possible means to not exceed 8,600 feet. Converted to the current unit of the Shang Dynasty, 8,500 feet is a little over 28,000 meters. To fly to such an altitude, you need to prepare for a long time, fly for half a day, and then you can only stay in the air for a few breaths!
At high altitudes, there are evil spirits and strong energy that make people unbearable; in addition, the spiritual energy is thin at high altitudes, which is even more fatal to practitioners.
Now, after the plane takes off, it only takes a cup of tea to fly to an altitude of 35,000 meters. Sitting in the plane, you can calmly look down at the earth.
The earth seemed to have turned into a chessboard, with white clouds underfoot. The sky at high altitude was exceptionally pure, so pure that it was intoxicating.
The pilot next to him whispered, "Senior, as you ordered, we will stay in the air for six hours. The current altitude is 35,331 meters. The weather is clear, with a light breeze and few clouds, which is very conducive to your practice and understanding of the world. The plane will start a slow circular flight, circling over the ground of the Shang Kingdom for half of the time and circling over the East China Sea for the other half of the time."
Ning Chengzi, the Grand Elder of Lingyun Sect, looked around. He was high up and could see as far as he could. But when the distance was too far, his vision began to blur. Moreover, the sky was purer and the ground was more turbid. "Why is the vision in the distance blurring? Even with magic, it is difficult to see through the fog? Is this caused by the evil spirit?"
"Senior, after our research, we believe that this is not the influence of evil spirits, but the reason for the turbid air. The composition of the air is complex, and the main obstacles to vision are dust, water vapor, etc. According to our actual tests, on land, the visible range is about 150 kilometers to 200 kilometers, depending on the weather conditions. If the weather is hot and the moisture in the air increases, it may be very close. For example, the extreme case is foggy weather, where you can't see your hand in front of you. If the weather is clear but windy, there will be a lot of dust in the air, which will also affect the field of vision. If you are at sea or on the water, the visible range is about 50 kilometers to 120 kilometers. There is a lot of water vapor on the water surface, which will affect the field of vision. In addition, due to the influence of gravity, the air at high altitudes is relatively clean, and the closer to the ground, the more turbid the air."
"I see! Is this also science? I have been exploring this issue for a long time, but I didn't expect you to explain it so clearly in just a few words."
