Several people don't quite understand.
Liu Zheng chuckled.
In fact, when he heard about this ghost army, he thought it was ridiculous. If the people from the Western Region were really able to exorcise ghosts and gods, they would have annexed the entire Longyan Dynasty long ago.
so.
This is what I think!
The legendary ghost army that comes out of the ghost city from time to time is simply deceiving.
Liu Zheng can explain it with the scientific knowledge of later generations.
Those are a bunch of guys who make good use of mirages!
A natural phenomenon that takes advantage of the unique geographical environment and temperature. Mirages often appear at sea and in deserts.
It is the result of refraction of light in air layers with different densities in the straight upward direction. There are many types of mirage. According to the position of its appearance relative to the original object, it can be divided into superior mirage, inferior mirage and lateral mirage; according to its symmetrical relationship with the original object, it can be divided into orthographic mirage, lateral mirage, lateral mirage and mirage. Reverse mirage; according to color, it can be divided into chromatic mirage and achromatic mirage, etc.
Since ancient times, mirages have attracted the attention of the world. In Western mythology, mirages are depicted as the incarnation of the devil and a bad omen of death and misfortune. In ancient my country, mirages were regarded as fairyland. Qin Shihuang and Emperor Wu of Han once led people to Penglai to search for fairyland, and also sent people to Penglai many times to seek panacea. Modern science has correctly explained most mirages and believes that mirages are virtual images formed by light reflected by objects on the earth and refracted by the atmosphere. The so-called mirage is an optical illusion.
Mirages are closely related to geographical location, geophysical conditions, and meteorological characteristics of those places at a specific time. Abnormal distribution of temperature is the meteorological condition that causes most mirages. Desert Mirage Desert Mirage.
Take the formation of mirage. In the summer, the sun is blazing in the desert, and the sand is scorched. Because the specific heat of the sand is small, the temperature rises very quickly. The temperature of the lower air near the sand rises very high, while the temperature of the upper air remains very low, thus forming a temperature pattern. Abnormal distribution. Due to thermal expansion and contraction, the density of hot air in the lower layer close to the sand is small and the density of cold air in the upper layer is high. In this way, the refractive index of the air is small in the lower layer and large in the upper layer.
When the light reflected from a taller object in the distance is continuously refracted from the denser air in the upper layer into the sparser air in the lower layer, its incident angle gradually increases, and total reflection occurs when it increases to equal the critical angle. At this time, if a person walks backwards If you look at the reflected light, you will see a mirage.
The "mirage" that occurs in the desert is the refraction of sunlight when it encounters air of different densities. In the desert, the sand and rocks are baked by the sun during the day, and the temperature on the surface of the sand layer rises rapidly. Due to the poor heat transfer performance of the air, when there is no wind, the vertical temperature difference over the desert is very significant. It is hot at the bottom and cold at the top. The air density in the upper layer is high and the air density in the lower layer is low. When the sunlight passes from the high-density air layer into the low-density air layer, the angle of the light changes. After the refraction of the light, the oasis in the distance is presented to people's eyes.
Liu Zheng tried his best to teach these theories to several people in concise and concise words.
Who wants to...
They were still confused.
Jiang Xuan blinked: "Brother, do you mean that this ghost army was deliberately created by someone?"
Liu Zheng smiled and said: "Yes!"
He continued: "I think there are two possibilities. First, this is an army stationed in a specific place for a long time... They built a place similar to a ghost city somewhere outside this desert. , and then often appear in the eyes of passers-by as a mirage."
Everyone looked at each other in shock.
Although Qingyang Shuo was far-sighted, he didn't know much about the technology of later generations. He asked out of curiosity: "Sir, can this kind of mirage be created artificially?"
Liu Zheng smiled and said: "So, this person must be a genius of the world! He should not only use astronomy and geography, but also have other exquisite layouts, and this ghost city is just one of them!"
Qingyang Shuo also took a deep breath and said with a wry smile: "No wonder Xie Tianyao's 500,000-strong army was completely annihilated. People who don't understand these things will be really frightened."
Liu Zheng laughed loudly: "If this is just the reason for the destruction of the Holy Lord's army of 500,000, then we can conquer the Western Region!"
Everyone's morale was greatly boosted.
At this moment, Liu Zheng suddenly said excitedly, pointing to the desert hills not far in front of the cement: "Look, mirage, mirage!"
No one expected it.
What a coincidence.
As soon as Liu Zheng mentioned the mirage, the mirage appeared.
I saw that the place where the desert sky and the earth meet is a vast expanse of twilight. Above the layers of clouds, various buildings, pagodas, temples, streets...
It's not clear, but it's clear.
Everyone was stunned.
Liu Zheng was also very excited. In fact, the probability of something like a mirage appearing is still very low. There are many conditions that need to be met, and it was an eye-opener for me to meet them on the road this time. If the Long Yan Dynasty's 500,000-strong army had encountered this mirage earlier, they probably wouldn't have suffered such a miserable defeat.
Jiang Xuan ordered the entire army to stand still and watch the mirage.
The 150,000 troops were also amazed at the sight.
uncanny workmanship!
Gorgeous!
Incredible!
The whole army admired and pointed.
Qingyang Shuo laughed: "God bless our Yinzhou Army!"
"God bless the Yinzhou Army!"
“God bless Yinzhou!”
In fact, in ancient legends, this mirage was an ominous omen and heralded death. But after Liu Zheng's explanation today, everyone understood that if they could figure out what the mirage was in advance, they would have a better chance of winning when encountering the ghost army in the future.
Liu Zheng also smiled and said: "Loulan is not far away."
Everyone was overjoyed when they heard this.
They have been walking on the cement road for three days. It seems that they will reach Loulan in three days. Liu Zheng's journey was a bit unbelievable. The speed of paving the cement road during this thousand-mile journey was so fast. It has only been about five months and about half of it has been paved.
The labor force of the ancient people cannot be underestimated.
Even without the modern machinery of later generations, it can still unleash powerful combat effectiveness.
Otherwise, where would the Great Wall come from, and where would the pyramids come from?
With the planting of cement roads and Populus euphratica, the wind and sand on this road have reduced a lot. The army gathered together, and there was no confusion like the first time they walked into this desert.
"Let's go into Loulan!"
"Enter Loulan!"
Three days later.
Loulan finally appeared in front of the army, and everyone was overjoyed.
"Isn't this the town in the mirage?"
"Oh my God, exactly the same!"
"Look, at that time, I said it was a three-story building, and there was also the beauty of Loulan!"
The whole army was shocked and believed in Liu Zheng again.
Shancheng has finally arrived.
Liu Zheng couldn't help but smile when he remembered how embarrassed he looked when he first came to Loulan. It was here that he met Xiang Chenglin.
Today, it was Xiang Chenglin who came to greet Liu Zheng from afar.
as well as……
When Liu Zheng saw Reguli, who was gleaming in gold, had a graceful figure, and had gleaming eyes, and rushed towards her like a madman, he held his forehead and sighed, feeling very headache.
Accompanying him was Halik, who was already the King of Loulan.
"Defender of the Country!"
"See the Protector!"
"Lord Protector!"
All Loulan civil and military officials came to pay their respects.
Jiang Xuan was very excited.
Even Liu Zheng felt that Beier had face. He coughed dryly: "Liu Zheng met King Loulan, met Tai..."
Reguli had already jumped over happily, and immediately took Liu Zheng's arm and said with a smile: "Master Liu, you are still so polite to Reguli! You are a bad person, you haven't written a letter for so long... "
The whole army was dumbfounded.
Qingyang Shuo, don't look at anything inappropriate.
Qin Changfeng held back his laughter.
Jiang Xuan also turned red from holding back.
Legend has it that the Empress Dowager Loulan fell in love with our young master at first sight, and she has a fiery style and a beautiful widow. When we meet her today, she truly deserves her reputation.
The exotic look on her body made all the men look at her with fiery eyes.
Liu Zheng smiled bitterly: "Queen Mother, I haven't seen you for a long time, but... I still miss her a lot."
Who would have thought that with such a kind word, Reguli almost jumped up: "Did you hear that the young master said he missed me?"
Loulan Wenwu all bowed their heads, unable to bear to look directly at him.
What a great tragedy for the country...
How dignified!
Loulan is now a big country famous all over the world. How can we be embarrassed by you doing this!
Reguli suddenly said happily: "Sir, Reguli said before that he would hand over this kingdom to Halik and let us travel together in the mountains and seas together. I thought there was no chance... This time, I will go with you to the Northern Western Region. How are you?"
"What did you say?"
Liu Zheng was startled.
He looked at the Loulan people in confusion, but they still couldn't bear to look at him.
Regu Liyu waved her hand, and behind her, the 50,000 Loulan army was uniformly formed.
"See the Queen Mother!"
"See the Protector!"
Everyone.
They were all shocked.
Qingyang Shuo turned around for the first time and looked at the extremely excited Silly Baitian, Reguli.
He couldn't help but smile.
There is something extraordinary about this woman.
