Liu Che ignored Luan Da and asked Yan Ming to continue.

Yan Ming drew a simple diagram of the path of light, clearly depicting how the mirage was refracted from the other side of the earth's arc into mid-air.

While painting, he explained: "This kind of mirage is only a virtual image, and it can never be captured. Don't say it's a clipper, even the speed of light, and it can't catch up. ”

Liu Che didn't know what the speed of light was, but he thought it was a very fast thing.

"When you say that, I understand a little." As he spoke, he looked at the mirage that still existed outside and sighed.

Yan Ming knew that it was a sigh that Liu Che's dream of seeking immortals was shattered again.

He also sighed and said: "Your Majesty, seeking immortals is just for immortality, and the minister thinks that immortality cannot be achieved, but longevity can be achieved. I've told you a long time ago, but you just don't believe it! ”

Liu Che said: "It's me who is stupid again. Come on, send this Luan Da to me in prison, and wait for the fate. ”

The emperor, once you are fooled, can give you a lot of rewards. But once you understand it, you will never give up.

Luan Da is now facing this situation.

The poor and hateful Luan Da saw the catastrophe coming, and instead of reflecting on his mistakes, he shouted loudly at the critical moment: "Your Majesty, what Yanhou Yanming said may not be true. Your Majesty, please allow me to finish. ”

Liu Che was stunned for a moment and looked at Yan Ming.

Yan Ming nodded and said, "Let him say, what do I think?" ”

Liu Che nodded, and Xu Jia let go of Luan Da and let him kneel on the ground.

Luan Da saw that he had a glimmer of life, and hurriedly said: "Your Majesty, Yanhou said that it is not an immortal, but a refraction of light. The grass people thought what he said was false. It is to deceive Your Majesty. There is no evidence for this. ”

Yan Ming sneered and said, "Do you want evidence?" ”

Turning around, he said to Liu Che: "Your Majesty, the scene of the mirage, the minister can't show it to Your Majesty." But simple imaging, the minister still did it. ”

Liu Che was also stunned, he had never heard Yan Ming say that there would be such a thing.

Yan Ming took the telescope that Liu Che had used just now and skillfully disassembled it.

The eyepiece and objective lens inside are convex lenses.

Using the imaging principle of convex lenses to project some simple scenes on the white wall behind, this kind of experiment, Yan Ming has taken students to do it I don't know how many times.

When Yan Ming adjusted the distance of the convex lens and aimed it at the wall, a magical scene happened.

On the white walls, a blurred picture emerges.

Although it was not very clear because of the light around it, it was vaguely distinguishable that it was the scene opposite the convex lens.

Liu Che and Luan Da even saw themselves in the scene.

It's just that it's a handstand and a shrunken scene.

Yan Ming slightly adjusted the distance between the lens and the wall and the scene, only to see that the image was slowly enlarged.

"Your Majesty, this is the principle of lens imaging, and it is also the refraction of light. Although it is not the same as the principle of mirage, it can be regarded as a proof of optical imaging. This Luan has bad intentions. If you want to waste the country's money and food in the name of seeking immortals, it is shameful, and such people should be punished to set an example. After Yan Ming's simple explanation, he pointed the finger at Luan Da.

Such people are extremely unworthy of sympathy. He didn't intend to harm him, and this guy wanted to find trouble for himself because of his own selfish desires.

For this kind of person, Yan Ming has never been soft.

"Xu Jia, call someone, press Luan Da out of me. Put them in prison first, and let the Yamen have a good discussion about how to punish the crime. Liu Che said.

Xu Jia agreed, and dragged Luan Da, who couldn't stop kowtowing and begging for mercy, out.

After dealing with Luan Da, Liu Che stretched his waist and said, "Why is such a person repeatedly banned!" ”

Yan Ming smiled bitterly and said, "If Your Majesty is fooled, the glory and wealth of the first life will be at your fingertips." People die for money, birds die for food, and many people dare to take risks. ”

Liu Che nodded, deeply convinced.

"By the way, you just said that the earth we live on is round. Judging from the mirage formation you mentioned, this land should really be round, so I can make it clear. Liu Che said.

Yan Ming clenched his fists and said, "The minister doesn't dare to deceive Your Majesty." This world is indeed round. It's a pity that we don't have that big thing, come on and present it in its entirety. ”

"Big things, as long as there are enough manpower, can be built." Liu Che said confidently.

Yan Ming was reminded by his words, and suddenly smiled: "If Your Majesty exhausts manpower and builds a huge microscope, he may be able to crack the code of human longevity, and at that time, longevity may not be a problem." ”

"Really?" Liu Che was obviously interested.

Yan Ming nodded and said, "I don't dare to guarantee it, but at least the probability is better." ”

"I'll have time to draw a drawing of my microscope, I'd like to see it." Liu Che said.

Yan Ming nodded.

If there is one of the best construction teams in the world, the contractor.

That must definitely be regarded as the emperor of all dynasties.

Whether ancient or modern, Chinese or foreign, emperors are very capable and good at tossing architecture.

The Great Wall, the pyramids, and the Colosseum were all built by emperors to satisfy their own rule or selfish desires.

These buildings, without exception, have become witnesses of history and treasures for the future.

"Let this mirage and Luan Da make it, I have forgotten the point of going to Penglai this time." Liu Che said, walked to the edge of the high platform, and looked at the steel ships parked in the harbor.

Yan Ming also followed him and stood on the edge of the high platform, and said: "This ship was built in New Taipei City, and the minister gave it a name, New North. ”

"New North, good, good name. I heard that you also set up an academy of sciences in New Taipei City? Liu Che asked.

Yan Ming nodded and said, "Your Majesty, the Academy of Sciences will become the national treasure of my Han Dynasty in the future." ”

Liu Che looked at the steel ship in the water and said, "How many of this ships are studied by the Academy of Sciences?"

Yan Ming said: "Almost all of them were built together by ministers and people from the Academy of Sciences. ”

Liu Che nodded and said, "New Taipei City is bitterly cold, what do you need over there, just tell me." ”

Yan Ming thanked him.

Liu Che pointed to the New Taipei and said, "Tell the crew to get ready, I want to take the New Taipei and feel the fastest ship in the Han Dynasty." ”

Yan Ming nodded and said, "No problem." However, before taking the New North again, the minister has one more thing to report to His Majesty. ”

"What's the matter?" Liu Che asked.

Yan Ming told Liu Che about the encounter with pirates in the sea, and then said: "The group of aliens rescued by the minister is said to be from the Roman Empire. This empire was very powerful, not far behind the Xiongnu. Although the envoy they sent was dead, the woman was not a mortal person, and could learn more about Rome. ”

"Rome, interesting." Liu Che was obviously interested.

A belligerent emperor, the most boring thing is that he has no opponent.

Now, Rome appeared at the right time, which made Liu Che interested.
