For the audience of Han and Tang Chang'an, this picture can be said to depict the most magnificent scene with the shortest brush and ink.

Looking at the changes in China for 2,000 years, a picture is enough.

Moreover, the audience in Chang'an in the two places also faintly realized that this picture is expressed in numbers throughout, without a sentence of conclusion, but the meaning of what it wants to say is still clearly expressed.

This also seems to be a usage of arithmetic...... The people in both places kept this idea in their hearts for the time being, and planned to go back and explore it.

And at this moment, a few words slowly floated by on the light curtain:

Hey, if you want to talk about the three major cases in the late Ming Dynasty, then I'm not sleepy at all!

The UP master also said that this issue is mainly a review of Han and Tang from the perspective of climate, and the three major cases should not be served.

Indeed, speculation about the causes of the Red Pill case, analysis of doubts, and summary of the aftermath cannot be explained in a few words.

Zhu Changluo was too unlucky, and he could only say that he experienced two of the three major cases in the late Ming Dynasty, and one of them was even the protagonist, and finally won the name of the Aphrodisiac Emperor and the Son of Heaven in January, which is rare in history.

It can only be said that a red pill involved how many palace affairs in the Ming Dynasty were involved, because the blood of the virgin moon caused the palace maids to plot to rebel, but it is a pity that the attack is still light, and the Renyin Palace has not really strangled Jiajing Lao'er, otherwise the history of the Ming Dynasty can be three more exciting.

Zhao Guangyi: The content of this picture is complicated, but what is the essence of it? 〗

In the conservatory in Bianjing, the previous cheerful atmosphere has disappeared.

Zhao Guangyi hugged his head and did not forget to defend loudly, and behind him, Zhao Kuangyin was holding a jade axe.

"Brother, although my brother is good at calligraphy, but he doesn't know anything about the way of gongbi, if he forcibly copys, wouldn't he be a tiger who can't become an anti-dog?"

Seeing that the eldest brother didn't say a word, Zhao Guangyi was also anxious, and continued:

"Brother, don't you want to hear about the rule of Tang Taizong and Zhuge Wuhou? As long as you get one or two, you can also make me Song have a king who keeps it, not like that......"

With a "bang", the small jade axe in Zhao Kuangyin's hand flew out and smashed on Zhao Guangyi's shoulder, which was the sound of falling to the ground.

So the words in Zhao Guangyi's mouth quickly turned into begging for mercy.

But all this had no effect on Zhao Pu, he didn't see or hear it at all, he just stuck his head out and almost poked into the light curtain.

As one of Zhao Kuangyin's most relied on right and left hands, and also one of the masterminds of the Chen Qiao Mutiny, Zhao Pu's mind was quite active, and when he saw the light curtain with his own eyes at the first glance, he understood that the biggest variable since the turmoil in this feudal town had finally come.

And at this moment, seeing the content of a picture, he was even more convinced of this, and he relied on his memory to memorize the few simple lines and numbers about Song in his head.

It's just a pity that the picture didn't take long to show and couldn't write down more content.

But at this moment, looking at the words floating on the light curtain, the content of the Ming Dynasty was enough for Zhao Pu to widen his eyes.

……

"Jiajing ......" Liu Bei raised his head and thought for a while, only feeling familiar but unable to remember, so he looked at Kong Ming for the first time.

"It is the king of superstitious Taoism, and the atmosphere of worshipping Huang Lao Xuandao in the Ming Dynasty."

After hesitating for a moment, Kong Ming continued:

"This Jiajing seems to be the leopard room...... Emperor Zhu Houzhao of Zhengde succeeded to the throne after the collapse of Emperor Wanshou. ”

It seems that the memory of taking and adjusting is not all good, and Kong Ming couldn't help but wake up in his heart.

The juniors talked about Da Ming very little, but now they know enough for Kong Ming to make a guess.

Good magic, seeking immortality, and being happy in the alchemy room, these characteristics are enough for Kong Ming to associate this Jiajing with the Emperor of Wanshou.

And now that he knows that his madness of collecting "medicine" caused the palace maid to kill the king, he can already outline a not very good impression.

Although the words are simple, everyone is also interested in listening, after all, the various things of the Tang Dynasty are too similar to the Han Dynasty, and eating melons to the Ming and Song Dynasty will make everyone feel fresh.

And sighed from the bottom of my heart: I can play.

"Doctor Zhang, what's that...... Are those things really powerful? ”

Zhang Fei even asked Zhang Zhongjing with a little curiosity, but got an unceremonious answer from the old gentleman:

"Nonsense!"

And in his heart, Zhang Zhongjing also drew a distinct gap between medicine and Taoism:

Don't come to the side.

[Let's put aside the messy things for a while, or let's continue to talk about one of today's protagonists.

The rise and fall of the Tang Dynasty is inextricably linked to climate change, but if you take a closer look, the inside story is also very complex.

But on the whole, the decline of the Tang Dynasty is probably difficult to separate from the wild damage it has caused to the environment.

As early as when talking about the change of coal, everyone already knew that the large number of applications of coal in the Song Dynasty was essentially a shortage of charcoal, and coal had to be developed for heating.

As the saying goes, the predecessors cut down the trees and the descendants suffered, of course, this pot still has to be carried by the Tang Dynasty.

Forests were an important environmental asset in ancient dynasties, providing hunter-gatherers and coal for cooking, heating, and iron smelting.

According to incomplete statistics, at the peak of the Tang Dynasty, the forest coverage rate in the middle and lower reaches of the Yellow River reached an unprecedented 35% due to the abundant rainfall brought by the rising temperature.

Around the time of the Song Dynasty, this figure was less than 9%, that is, the Tang Dynasty completely destroyed 70% of the existing forests in the middle and lower reaches of the Yellow River in about 200 years.

We are clear about the problems of soil erosion, soil deterioration, frequent droughts and floods caused by the large-scale destruction of forest vegetation, so we will not repeat them.

This is also one of the reasons why the Song Dynasty governed the Yellow River several times, but all of them treated the symptoms but not the root cause.

So let's look back, the Tang Dynasty benefited from the rise in temperature, so the climate was pleasant, so how good was such a climate?

According to incomplete historical records, in the 300 years of the Tang Dynasty, there were 19 snow-free winter years in Guanzhong, ranking first among all dynasties in Chinese history.

The warmer climate has shifted the snowfall line northward, and there are two most significant effects in this regard:

The pleasant climate reduced the pressure on the nomads to survive, and gradually converged to stability and unity internally, allowing the Tang Dynasty to defeat and confine the nomadic areas at a relatively low cost.

The snowfall line moving north makes the farming area unprecedentedly expanded, the western regions can garrison the cultivated fields, the northwest Longyou can "Lu Yan look at each other, mulberry and hemp fields, the world is called rich as Longyou", the vast agricultural area in the north is very unimaginable in the Ming Dynasty.

But Tang Dynasty said it wasn't over yet.

According to today's research, the area where rice could be cultivated in the Tang Dynasty stretched from the Hexi Corridor in the west, to the southern foot of Hetao and Yanshan Mountain in the north (near present-day Baoding, Hebei), and to the Bohai Sea in the east, which is unimaginable for all other dynasties. 】
