Li Xuan has been in this era for some years, and this era has changed from the original two years of Anjian to the fifteenth year of Xuanping, and it has been sixteen years since he counted on his fingers.

In the past few years, in general, there have been man-made disasters and not many natural disasters in China.

In the first two years, the Huaihe River basin and the middle reaches of the Yellow River also rained, but the Tang Empire's massive investment in water conservancy construction funds was not in vain, and it played a considerable role, so although there will inevitably be some small-scale floods, but it did not cause a major disaster.

And now, Li Xuan looked at the gloomy sky and the raindrops that kept falling outside the house, and his brows were furrowed.

This rain has been raining for two days in a row, which is not a good sign, although this rain is not always a downpour, but it has not stopped!

This year's rainy season came a little early, and it was a little fierce!

Retracting his gaze from the window, Li Xuan returned to the desk and picked up the meteorological report sent by the Royal Institute of Technology, as well as the meteorological report from the Royal Academy of Sciences next to him.

However, Li Xuan directly put down the report of the Academy of Sciences, because he didn't need to read it to know that the gold content was not large, or he simply copied the report of the Astronomy Department of the Royal Institute of Technology.

Originally, Li Xuan wanted to establish the Royal Academy of Sciences as an official top-level research institution, but later shifted his focus to the Royal Institute of Technology, which gradually degenerated into mediocrity despite having such a big signboard.

By now, it has basically become an ornament, although reports are occasionally submitted, but in fact, many of them are directly copied from the relevant statements of the Royal Institute of Technology, which has no practical value.

Today's Royal Institute of Technology is currently the top of the Tang Empire, and it can even be said to be the only comprehensive scientific research institution.

There are more than 10 departments inside, which basically cover all disciplines, and the teachers and students in them are all real geniuses selected from thousands of miles across the country.

The weather report sent by the Royal Institute of Technology predicts that it will still rain in various parts of Zhili in the next month, and the rainfall will not be small.

What's even worse is that it is not only raining in southern Anhui and other areas, but also the rainfall belt will gradually move northward, and then enter North Anhui Province, Jiangbei Province, and even Henan and Shandong.

For this reason, researchers at the Royal Institute of Technology judged that in the next month, because of the heavy rainfall in Henan, Shandong, North Anhui Province and Jiangbei Province, and the rainfall will far exceed the rainfall of two years ago, it is very likely that the Yellow River will burst its banks, causing a huge flood.

As soon as they came to the conclusion of the study, they were immediately sent to the palace in an expedited manner.

When Li Xuan saw this report, he naturally attached great importance to it, if this report was correct, then although it was only the beginning at present, the situation was probably more serious and serious than two years ago!

The slightest mistake can lead to large-scale flooding.

And this situation is not allowed by Li Xuan!

Now that the empire is in a stage of rapid development, it cannot be interrupted by a flood!

It's going to rain, and he Li Xuan can't stop it.

But to prevent floods and reduce losses as much as possible, Li Xuan can do it.

After looking at the meteorological report in his hand again, Li Xuan immediately pushed open the door of the office directly with the meteorological report, and then said to the secretaries outside: "Pass the order, let the ministers of the ministries, the Privy Council, and the Command Department enter the palace for a meeting!" ”

The secretaries outside suddenly saw Li Xuan come out, and then heard Li Xuan say that a meeting was going to be held, and they all thought about what happened in their hearts?

But no matter what they were thinking in their hearts, at this moment, they all moved, and with a simple arrangement, more than a dozen secretaries trotted out directly to find those ministers.

Some went to the ministers on duty in the Imperial Study, some went to the cabinet and other yamen to find ministers, and some went to the generals of the army and navy.

Although Li Xuan didn't say the words urgent or immediate, everyone was not stupid, but the Son of Heaven didn't say anything about the clear time, which meant that the Son of Heaven was about to hold a meeting immediately.

At the same time, the cabinet secretary and the secretary of various military departments attended the meeting, which means that this will be a military and political meeting, and it will also be an emergency military and political meeting.

This kind of thing rarely occurs in the Tang Empire.

Even last year, when I fought the Tatars, I didn't have one.

What the hell is going on?

These secretaries didn't know very well, and the many ministers who suddenly received the summoning order were even more confused, and they thought carefully that nothing major had happened in the near future.

Since the end of last year, the Tatars in the north are very honest now, and there is no sign of large-scale mobilization of troops to launch an offensive, and the Tang Empire also spent a lot of military money because of a big war last year, and there is not much spare time to launch another large-scale offensive campaign.

Therefore, on the northern side, although small and medium-scale battles have occurred from time to time since the beginning of this year, it is estimated that large-scale battles will not be able to be fought.

Except for the north, the other directions are also stable, and there are basically no signs of a large-scale invasion by foreign enemies, even if the Portuguese and the empire fall out, but not to the extent that an emergency military and political meeting should be immediately called.

If there is no external enemy, it is civil strife, and many ministers are speculating, could it be that there is some big and important case? And it is very likely that it involves a rebellion, otherwise, with the current size of the Tang Empire, ordinary trivial matters will not be so fussy at all.

Many ministers have their own guesses, but few people can guess that Li Xuan summoned them just because of a two-day rain!

Because they didn't know that researchers at the Royal Institute of Technology had already judged that this heavy rain was very likely to last for more than a month, and it would affect the entire middle and lower reaches of the Yangtze River.

Many ministers took horse-drawn carriages to enter the palace quickly, because the distance between the yamen of the various ministries and the palace was not too far, except for some ministers who were on a business trip, most of them soon arrived at the palace annex.

After entering the palace, everyone was taken to the conference room by the secretariat, and the ministers who had just entered the conference room were immediately handed a report, which was the climate report urgently submitted by the Royal Institute of Technology.

When everyone saw that the report said that there might be a heavy rain in the entire middle stream of the Yellow River and the Huaihe River basin for a month, many people's faces changed instantly.

None of the people who were able to enter this room, whether they were military generals or cabinet ministers, were stupid, and all of them were killed from the competition of thousands of armies and horses before they finally became imperial dignitaries.

Just by looking at this report, they can immediately associate the seriousness of the matter!

"If this is really for another month, the water level of the Yellow River will inevitably rise on a large scale, and I am afraid that the embankments in many sections of the river will not be able to hold it at that time!"

"Isn't it, once a flood is caused, the damage to the empire is far more serious than the Tatar invasion in the north!"

"What are the Tatars, with my Tang Army, the Tatars don't expect to be able to cross the Great Wall!"

"We must immediately and strictly order all localities to strengthen river defenses, and tens of millions of people will be affected along the Yellow River and Huai River, and there will be no room for mistakes."

The ministers who looked at the report were full of discussions, and their tones were full of worry.

Because everyone knows the seriousness of the matter.

If this rain really falls for a month, I am afraid that the entire middle reaches of the Yellow River and the Huaihe River basin will be affected, and there are a large number of people in this area.

And there are a lot of industry and commerce in the region, although the total amount is not large, but the potential is great, such as Huai'an, Yangzhou, Xuzhou, Kaifeng and other cities in the Yellow River and Huaihe River basins, because of the canal and the Yellow River's river transportation, has become the key area for the empire to develop industry in the Central Plains.

If this is destroyed by the flood, it means that all the industrial construction of the empire in the Central Plains and the northern regions in the past few years will be wiped out.

Of course, even if all the industries in the above areas were destroyed, it would not be considered a loss to the economy, because the industry and commerce of the empire were mainly concentrated in the Yangtze River and Pearl River basins.

The economic powerhouse of the Tang Empire is Zhili, one government and four provinces, and then Jiangxi, Hubei, and Hunan provinces can also be added, but the latter three are mainly agriculture-based, especially the two provinces of Huguang and Guangzhou, which have been developed by the empire as a new granary.

These areas not only temporarily occupied a large amount of the empire's grain production, but also accounted for more than eighty percent of the empire's industrial output, and several large cities along the Yangtze River were among the most important industrial areas of the empire.

Wuchang Industrial Zone is a new large-scale industrial zone built by the empire in the last five or six years, and Dangtu Industrial Zone is the most important heavy industrial base of the empire, not to mention Shanghai, the largest industrial city of the empire, and Jiujiang, Anqing, Zhenjiang, Jinling and other places, and even Yangzhou is also an important industrial and commercial city of the empire.

If the Yangtze River swells dramatically, flooding both sides of the river will cause immeasurable losses to the empire.

It is precisely because the Yangtze River basin is so important that in recent years, more than half of the water conservancy funds invested by the empire have been used to control the Yangtze River basin.

Of course, the Yellow River and Huai River basins are more problematic, so about 40% of the funds are temporarily used, and the remaining layer of funds is spent on the Pearl River basin and other rivers.

A lot of money was invested in water conservancy, which is why the empire has not suffered any large-scale floods in the past many years.

But this time, the rain is a bit heavy, and I'm afraid the Yellow River won't be able to hold it!

While everyone was discussing, with a 'Your Majesty has arrived', Li Xuan, the Son of Heaven, also walked into the conference room, and the first sentence he said was: "You have all read the report, and you all talk about it, how to deal with it!" ”
