"As Your Majesty said, during the Wu Dynasty of Han Dynasty, the climate was warm, and Hexi, Bingzhou and other places were not cold, so it could move 300,000 people to guard the border."

"At the time of Zhaoxuan, there were no major disasters. Even in Luntai and other places in the outer border areas, they could also cultivate farms and cultivate. Therefore, the Han family opened the Western Regions and set up a Protectorate."

If it weren't for the Fifth Reunification Heavenly Official who had investigated the matter thoroughly, Huan Tan wouldn't have thought about this. Now he reminded that the climate over the past few decades has indeed become colder and colder.

The changes in things happened during the reign of Emperor Yuan of Han, who was also an unlucky person. During his reign, it was a 16-year period of natural disasters. When he ascended the throne, the 11 counties and states in Guandong suffered heavy floods, the people were hungry, and people fed each other.

The following spring of the following year, the Longxi earthquake was destroyed, the city walls were destroyed, the ancestral temples were destroyed, and the people were killed. In the autumn of the same year, the earthquake broke out again, the mountains collapsed and the ground was broken, the water springs surged, the North Sea flooded, the people were in trouble, and they went into exile everywhere. In the third year of Chuyuan, there were droughts and Zhuya, and the counties rebelled. In the fifth year of Chuyuan, there were "different stars", the sun was dark, the crops were not harvested, and the frost fell.

This weak emperor, the country he was in charge, had many disasters and difficulties. This made Emperor Yuan of Han "thrill and tremble, thinking about his mistakes day and night, and dare not be in vain." He reduced his diet, used less garden horses, and withdrew from Yuefu, thinking: "When the era is changed, it will never be like this?"

However, the first year of Yongguang was even worse. The spring frost and summer was cold, the sun was green and the sun was empty, the world was famine, the beasts were gone, the Huns were hungry, and Huhanye Shanyu asked for food urgently. This time, Emperor Yuan of Han refused to take the blame, so he rarely looked down upon him and issued an edict to accuse the minister of dereliction of duty. The Prime Minister resigned for the disaster and caused a disaster in Dingguo.

However, dynasties have dynasties, and naturally have natural laws. Climate change does not end with the resignation of a minister. It gradually becomes colder and dryer, which continues to torture Emperor Yuan of Han. Emperor Cheng of Han for decades, and there are constant concubines, ministers take the blame, and even commit suicide for this...

By the time Emperor Ai of Han took over, the government became increasingly dark and corrupt, and with the blessing of natural disasters and man-made disasters, the people were trapped in the seven deaths and seven deaths.

This is the era when Huan Tan became an official: "Wang Mang and other scholars believed that the Han Dynasty was impure and its energy was exhausted. As long as the dynasty changed, everything would end. The world was harmonious and the world was in harmony, and the world was in good weather."

There is no need to say the result. After Wang Mang came to power, there were more disasters. From the Spring and Autumn Period, it was difficult to produce millet in the rice seeds in the northern counties. When large tracts of bamboo in Guanzhong died, and when the coast of the Bohai Sea began to freeze over the years, it meant that the climate was colder and dryer. Wang Mang stepped on the accelerator on the downhill road, and the chaos eventually led to the collapse of the Xin Dynasty.

Wu Lun smiled and said, "The world believes that it was Wang Mang's rebellious actions that caused the Yellow River to break, and the yin and yang were imbalanced, and the world was extremely cold and severe. Now the new house has been dead for more than ten years, and the north has not improved. I heard that Liu Xiu's national teacher Qiang Hua has recently blamed Yu for his crimes."

Fortunately, the fifth reunion did not follow the old path of relying on auspiciousness and taking advantage of yin and yang disasters and strange things, otherwise he would be extremely embarrassed.

"I only now know that in the past few decades, the Emperor of Han, concubines, relatives, Rongdi, and ministers who have been accused of this for many years, actually cannot bear the responsibility for the disorder of yin and yang, because this is a part of the constant movement of heaven!"

Before the fifth reunion traveled, I heard about the famous "Little Ice Age", but I didn't expect that I was hit by myself.

When this fact was confirmed by the previous calendar and the records of disasters and disagreements over the past decade, even Huan Tan felt a sense of despair that was overwhelming: "Since it has nothing to do with human affairs, when will it improve?"

Wu Lun rolled his eyes: "God knows!"

What they encountered was a huge change that would not be transferred with human will, a faint fluctuation during a large ice age. Perhaps it had reached its end, perhaps it had just begun, and the peak of the cold was far from here. It would last for a hundred years, or two hundred years, three or four hundred years, and it might not have to rebound until the Sui and Tang dynasties in history.

But the fifth reunion is not that pessimistic. Although the climate in the past ten years is cold, it is actually just like the Qin and Han Dynasties, and it is almost the same as in later generations.

"The same sentence: responding to it will be good if it is governed; responding to it will be bad if it is disordered."

"If you strengthen your foundation and use it, then the sky will not be poor; if you keep it ready and move, then the sky will not be sick; if you follow the way without being discontinued, then the sky will not be in trouble!"

I heard that every time the temperature drops, agricultural grain harvests will reduce production by 10%, so we have to develop productivity and make up for this gap. In order to allow the dynasty founded to last until the next warm period, we have to improve production relations and avoid its collapse too quickly. On these two roads, he is a ox pulling a cart, and he has a long way to go.

"There is a third solution."

Fifth Ren looked at the open direction of the gate of the court, and seemed to see the good medicine to save the crisis: "Enter the South!"

...

"Only a wise man like Junshan can understand that the climate is colder because of the normal behavior of heaven. If the rest of the unconscious people know it, they may promote the "Wei Wu has no virtue, so the yin and yang are not in harmony, which is even worse than that of Wang Mang". This matter cannot be promoted for the time being."

After today's meeting, Huan Tan was able to go back to think about the knowledge, but the fifth reunion still had to set up simple eyes on the bridge of his nose and continue to look at the memorials stacked like mountains.

This has been screened by Shangshutai, and it is still so many. He is already thirty-three this year. Because he is diligent in exercise, his health is not bad, but his vision is getting worse and worse. Lighting candlelight at night is really not something that people do. The fifth reunion feels that he will probably not have the chance to shine in the light of the electric light again in his lifetime.

As the end of the year approaches, there has been no big deal recently. Only when I read a memorial, I was so angry that I was very upset.

However, it was Wu Han, the "General of Zhenbei" who reported that the fifth reunification divided Hexi and formed a "Northwest Military Region" with the border of Bingzhou to face the Huns directly, and was ruled by Wu Han, and assisted and supervised by the second governor of Bingzhou.

"Please reply to the Fang, Wuyuan Shu"?" With Wu Han's knowledge level, it would be good to be able to write the title clearly. The fifth reunion cursed: "I wonder who I have found to use to write this time."

Sure enough, if you read this memorial carefully, it can be considered a great article.

"Now the land of Bingzhou Shuofang and other places are the key points of the world and the country's foreign guards, which are recorded in the "Li of Zhou". In the 33rd year of Qin Shihuang, Meng Tian was sent to expel the Xiongnu, seize the land in Henan, and to build a Great Wall, cross the river and occupy Yinshan, and wind down to the north. During the Chu and Han dynasties, the Xiongnu were rekindled and crossed the river south, and he took the opportunity to capture the land seized by Meng Tian, ​​which was a great trouble, and the beacon was in Ganquan Palace."

"In the second year of Wuyuanshuo in the Han Dynasty, Wei Qing and others were sent to the Xihe River, and they went to Gaoque to collect the land in Henan. The master Yan said: Henan's land was rich and blocked the river outside, so they could be used to expel the Xihe River, and they could be used to transport garrisons and grains inwardly, and broaden China, and prepared the basis of borders. So he built Shuofang City and repaired the blockades that Qin Mengtian had built, because the river was solid. Since Shuofang was built, the Xiongnu declined, and then he entered the court to the Han Dynasty."

"When Wang Mang was killed, he went against the enemy. Xihe, Yunzhong, Shuofang, and Wuyuan were all destroyed. The Xiongnu revived and supported Lu Fang and jumped into Liang for ten years. Although Lu Fang was killed, he hung his head and barbarian residence, Yanmen, and Dai County surrendered to our dynasty. However, Shuofang, Wuyuan, Yunzhong, and Dingxiang were still under the jurisdiction of the Xiongnu, and he is still suffering."

"I have been guarding the border for many years. I have been fertile and fertile land, abundant water and grass, and the land should be produced and herd. The Xiongnu got it, and they can be trained by horses. They can attack Shangjun in the south and force Guanzhong. Once they collude with Gongsun Shu invade the south, the sea will be disturbed. I think it is better to follow the story of Qin Emperor and Han Wu, chase Hu to the north of Yinshan Mountain, rebuild cities, farm farms and camp, and imprison the enemy outside the country. This is a perfect strategy!"

It seems that Wu Han has invested money this time and found a good pen. This memorial sounds decent, but in the eyes of the fifth reunion, Wu Han has committed his biggest shortcoming: he has no view of the overall situation!

"Bingzhou is the gateway to Guanzhong. Of course it is important and must be restored, but it is definitely not now."

After confirming that he was in a "little ice age", the fifth reunion became more firm in this view, such as fertile wilderness, abundant water and grass, and suitable for grassland. He also stayed in Xinqin. He knew that these words were OK in the Hanwu period, but now they are a bit overwhelming. In the past, Hetao could even grow rice, but now the grain production is not as good as before. In addition, the war was broken and the people fled and moved, even if they won the decisive battle with the Huns and reoccupied the four counties again, and wanted more than 100,000 troops to survive in the frontier for a long time, it would be a huge problem. In the case of drying and cold weather, maintaining the rule of Bingzhou would be a financial black hole...

Not to mention, when Wu and Shu were still alive, relying solely on the north to fight to the unified Xiongnu Empire, this is to continue playing the "Romance of the Four Kingdoms" for a long time.

"Times change, the climate changes, and Wei can no longer follow the old path of the former Han Dynasty. Our future is not in the north, not in the Western Regions, but in the south!"

So the poor Wu Han worked hard to find a memorial written by the gunman, and was "kept at the end". The emperor would encourage him, but would not accept it. When General Wu stayed old in Bingzhou, he might have the opportunity to fight back against the Huns. At that time, his resentment that had been holding back for many years would probably be completely vented on the Hu people...

The five-year rest period has arrived. After five years of rest, the troops are ready and the people have recovered slightly. It is time to carry out the great cause of unification to the end.

Winter is approaching, and it seems like a sharp sword hanging over your head, which gives the Fifth Rondo a reason to march into the South.

But where to fight first? The three generals who placed the fifth relationship on the north-south boundary have three different views.

As the New Year's Day of the 10th year of Wude is approaching, Weiyang Palace is busy preparing for a grand celebration, but the fifth reunion is examining the three cards in his hand in the closed palace...

General Cen Peng, the general of Zhennan, was in charge of Yuzhou and Jingbei military affairs, which was equivalent to the "Central Plains Military Region". Facing Chengjiaba County and the two divisions of Jingnan in the Eastern Han Dynasty, he wanted to use troops to the Jianghan Plain five years ago. If Wu and Shu fought hard, it might trigger a decisive battle. If Wu and Shu remained stable, the Wei army could cut off the Wu and Shu connections and defeat them one by one.

General Geng Bozhao of the chariots and cavalry generals were in charge of military affairs in Xuzhou, which was equivalent to the "Eastern Military Region". Xiao Geng had been looking at Huainan for a long time. He believed that the Wei army could go straight to Jiangdu. In order to protect this place, Liu Xiu had to fight the Wei army in Huainan. If Liu Xiu gave up on his journey and retreated to Jiangdong, he could further compress his power. Once Huainan is lost, Liu Xiu will no longer be in a state of chaos. Even a few years ago, he ordered Deng Yu to take over Jiaozhou when the fifth reunion destroyed Lu Fang and ruled against Qiang and Hu.

Finally, Ma Yuan, the general of the Cavalry, still guarded Longyou, but his headquarters was in Yongcheng, Youfufeng. Relying on Wudu County, which was captured five years ago, it had crossed the Qinling Mountains and directly threatened the portal of Bashu: Hanzhong. Ma Yuan strongly asked to attack Hanzhong first, so that the troops stationed in Guanzhong can be reduced and the preparations for further destruction of Gongsun Shu...

Looking at the boundaries of the disputes between the Three Kingdoms on the map, looking at the "pawn", "car" and "horse" representing Cen Peng, Xiao Geng and Ma Yuan - this is a good thing carved by Huangyu during the time of Wang Mang.

The front hooves of the horse chess soar into the air, like galloping, and can overcome difficulties and obstacles and jump to unexpected positions of the enemy; the chess has wheels, and they can traverse in all directions anytime and anywhere; the soldiers squat half-kneel, holding spears and shields, like to advance steadily and eat away at the enemy step by step.

After pondering for a long time, Wu Lun said intimately: "This battle is about the unification of the world, and it is not a battle in a corner, but a move that affects the whole body. Liu Xiu has been dormant for several years, lying on firewood and tasting gall, and he should not be easily dealt with, and the three generals should not fight each other. Instead, they should be launched one after another, real and real, and mobilized the enemy."

He then slowly lifted the "horse" representing Ma Yuan and smashed it hard up the Han River!

"First attack Hanzhong, and let Gongsun Shu help the north in a hurry, so that the Shu soldiers had no time to go to Jiangling!"
Chapter completed!
