The king of the grape country was escorted to Luoyang, Gao Yiming ordered a demonstration at the entrance of the vegetable market in Luoyang, and at the same time only provided happy soil every day, and then there were no officials to ask, as for the interrogation, Gao Yiming felt that it was completely unnecessary, and the compensation Ming army had swept the country of grapes, and the valuable things were now in the Ming treasury.

Then he didn't think it was necessary for him to see this king who had no hair left, and he felt that the end of this guy's good work was to die happily with the land.

When the people of Luoyang heard that this white-skinned and red-haired foreign hairy child was the king of grapes, new and old hatreds broke out together, rotten eggs and rotten vegetable leaves greeted together, and every day, and finally the king of grapes was frightened and hung up in less than three days.

Gao Yiming ordered to be thrown into the mass grave to finish the matter, and he really didn't have time to take care of the goods, and Gao Yiming was on his way to the academy at this time.

"Inspector Cai, are you sure our plane is already able to fly?"

"Back to the emperor, it's true, if I didn't see it with my own eyes, how would I dare to come to work for you."

"How high can I fly now, more than the treetops."

"Exceeded, how high are the treetops, flying higher than the mountains, running to the clouds."

Gao Yiming was happy when he said this, this is really the research of the aircraft.

"But—" Cai Dafa was a little afraid to say.

"But what? You can say whatever you want, you don't have to babble. ”

"Yes! - Your Majesty, according to the soldiers who returned from the flight, they will feel unwell, dizzy, and drowsy after entering the clouds, so 。。。。。。 ”

"So what?" Gao Yiming frowned slightly, this guy began to spit out again, it must be no good.

"Everyone suspected that our flying sky had alarmed the heavenly immortals and angered the heavenly immortals to be unhappy, so they came down to warn." Cai Dafa said mysteriously.

Gao Yiming was speechless when he heard this, but he couldn't blame them, the ancients classified things beyond their understanding as ghosts and gods, which is understandable.

"Anything else?"

"Some people also say that our plane is too noisy, which disturbs the heavens and people."

Isn't this a problem? Could it be that I misunderstood?

"Everyone thinks this is offending the gods, right?"

"Yes, Your Majesty."

"In a moment, you will find me a grasshopper, a candle and a glass bottle with a lid, and I will show you the reason on the spot."

"Eh, Your Majesty, don't you mean that we have offended the immortals?"

"Of course not, I don't know if there are any gods in this world, anyway, I haven't seen it, but I know what is going on with the pilot's situation, that's because the plane flies too high, there is a lack of oxygen, if you carry an oxygen cylinder, there will be no problem, but at present, this problem is not easy to solve, although we have oxygen production equipment, but the equipment is too large to be installed on the plane."

"So what can I do?"

"We can put the compressed oxygen cylinder in the cabin of the aircraft, replace it with this for the time being, and replace it when we develop a small oxygen concentrator."

"Emperor Shengming, it seems that this is the only way to do it at present."

Coming to the Daming College Aircraft Test Ground, Gao Yiming climbed on the high platform, and the teachers and students of the college saw that the emperor was coming, and immediately knelt down on the mountain and shouted long live.

Gao Yiming asked all the teachers and students to get up, and said loudly: "Gentlemen and students, I congratulate you on your great success, your research will make the Ming Dynasty stand in the world for a hundred years without falling, and your glorious achievements will also go down in history and shine for thousands of years!" ”

Listening to the emperor himself say that they will go down in history, how can this not make people explode, so countless students shouted loudly, the sound shook the world, Gao Yiming felt that the ground under his feet was trembling, and he was infected by this atmosphere, Gao Yiming also applauded unconsciously.

It took a long time for the excited crowd to calm down, and Gao Yiming continued: "The problems you encountered during the test flight, Inspector Cai also told me, first of all, I can be sure that the pilot fell into a short coma at high altitude is not the anger of the gods, nor is it that the pilot is not in poor health. ”

Clearing his throat, Gao Yiming continued: "This is because we have been living on the ground, the oxygen concentration on the ground is high, the higher the oxygen concentration is, the lower the oxygen concentration is, the altitude to which the pilot flies the plane, the oxygen is extremely thin, resulting in insufficient oxygen supply to the brain, so it will fall into a transient coma, a typical example is that I go to the Qinghai-Tibet Plateau, many people will have altitude sickness when they go up, because the altitude oxygen content is too small, and the human body is not adaptable." ”

"As for the reason for this, one is that the ground temperature is high, and the higher you go, the lower the temperature, and you all know the thermal expansion and contraction of the air. The second one is the gravitational pull of the earth, you can understand it as the suction of the magnet, under the action of the earth's gravity, a large amount of oxygen in the air gathers near the ground, the height at which the plane flies, there is too little oxygen. ”

"In order to give you an intuitive understanding, I will do an experiment below, and the superintendent has prepared the materials I need."

Saying that, Gao Yiming fixed the candle and lit it: "We all know that the candle needs oxygen to burn, I will now cover this locust and the candle with a glass and seal it, and you will see that the locust that was originally lively and jumping will wilt after a while." ”

Saying that, the candle in the glass slowly decreased due to the lack of oxygen, and finally went out, and the locusts inside also slowly slowed down, in order to prevent it from dying of carbon monoxide poisoning, when it could still move, Gao Yiming took away the glass, and after a while, the locusts that were originally slow became lively again.

The test was successful, and Gao Yiming was very proud: "Have you seen it, that's what happened, it's really not a ghost thing, it's oxygen that's doing the trick." ”

"It's really better to listen to your words than to read a book for ten years, but how to solve this problem?" Mr. Tan asked.

"It's easy to do, the best way is to install an oxygen concentrator, but our oxygen concentrator is too large now, and at present, we can only install compressed oxygen cylinders on the plane, which can maintain the amount for two or three hours."

"Wonderful, Emperor Shengming, I'll let people prepare, and then the two planes will fly together, please ask the emperor for guidance."

Looking at Mr. Tan, who was excited like a child, Gao Yiming nodded happily and agreed, it must be seen, isn't this what he did when he ran so far.
