How could Chongzhen not know about the drought in the north, and the political envoys from Shanxi and Shaanxi sent a note half a month ago to inform them of the situation there.

But fortunately, the potatoes and sweet potatoes that have been harvested for one season, even if the situation is bad, it will definitely not be like the hungry homeless people in previous years.

Liu Hong gradually asked about the canal that had been built for more than half a year, and Chongzhen summoned Fan Jingwen, the secretary of the Ministry of Industry.

The experience of the former first assistant made Fan Jingwen more cautious, and he sat in danger and waited for Chongzhen to ask about politics.

"Emperor Qi, Weichen was ordered to supervise the construction of canals in the north, and now a section of the Yanghe River in the west of Shuntianfu has been opened to water, benefiting Shenjingbao, Shaling, Jiajiaying and other towns.

The canals of Shanxi, Shandong, Shaanxi and Henan are still under construction, and it is expected that Shanxi and Shaanxi will need two months to be connected to water at the earliest, and Shandong will take two and a half months, and Henan will ...... It will be until late November at the earliest. ”

Fan Jingwen paused at this point and lowered his head.

"Hmph, I want silver for silver, ask someone to give it, more than half a year has passed, why wait another three months? You let me wait for three months, what can the people do? Ahem, ahem, ahem—"

Chongzhen was so angry that he began to cough again.

It's no wonder that Chongzhen is angry, if he really suffers from another three months of drought, it is estimated that there will be no harvest in the north this year.

"The emperor is angry, and the minister is guilty! Willing to be punished! Fan Jingwen saw Chongzhen's anger, and immediately knelt down to ask for guilt.

The imperial court had its own silver, and in order to cope with the great drought that was likely to continue in the north for several years, Chongzhen had already built a canal with the Ministry of Industry more than half a year ago.

For more than half a year, under the supervision of the Ministry of Industry, more than 2 million people were recruited in the four places, and even more than 100,000 prisoners of Zuoliangyu's bandit army were recruited to be strong men, and more than 14 million taels of silver were spent.

In the end, there was only water on the west side of Shuntian Mansion, and Fan Jingwen was embarrassed to say it even if he had a hard time in his heart.

"Your Majesty, dissipate your anger, dissipate your anger, how many times have the ministers said you, don't always be angry, your body can no longer be tossed." Liu Hong gradually got up and said while helping Chongzhen pat his back.

A few words directly twitched the corners of the mouth of Fan Jingwen, the secretary of the Ministry of Industry, tens of thousands of courtiers in the world, who dared to count the emperor in front of him? Still going to slap the emperor, don't die?

That's why the king of Anguo dares to do this, alas, why don't we have such a good life? Fan Jingwen knelt on the ground and didn't dare to breathe.

"Master Fan, didn't this king say you, you only played the result without stating the reason, didn't you find your own guilt?

Tell the emperor quickly, what is the reason for the progress of the canal supervision to be so slow? Liu Hong gradually saw that Chongzhen no longer coughed, but his face was gloomy and he didn't speak, and immediately signaled Fan Jingwen, saying in his heart that this guy is really out of the question.

"Your Majesty, most of the canals in the four northern provinces have entered the final stage, but they are just ...... The last few steps of construction are very difficult...... "Chongzhen didn't speak, and Fan Jingwen didn't dare to get up, so he knelt on the ground and explained the reason.

It turns out that the most difficult thing to build a canal is not the canal itself, after all, the ancients had nothing else, but there were many people who worked, and the people in many places were willing to contribute in order to beg for food and food, and even without wages.

The biggest difficulty of the canal is the junction between the canal and the river, there was no reinforced concrete in ancient times, and the risk of building a dam is extremely high, and it is likely to cause flooding if it is not operated properly.

The Yanghe River on the west side of Shuntianfu is okay, the runoff is small, and it can be dealt with by sending more people to take care of it, but the other three places are not so easy to deal with.

The Fen River and Yishui River in the mountains are all big rivers, and the runoff of the Wei River and the Han River in Shaanxi is not small, and the terrain is complex and mountainous.

And the river nan, the mountain is even more difficult, the Fen River and Weishui are the sons of this river, through the center of the two provinces, is the Yellow River!

At this time, the Yellow River is not the mother-like river that later generations praised, if the people of Henan and Shandong have to give the Yellow River a name, it is estimated that it will be called the Yama River and the Suoming River.

The Yellow River is full of sediment, which accumulates in the riverbed year after year, and in order to prevent flooding, the prefectures and counties around the Yellow River have to repair their dikes almost every year.

The riverbed of the Yellow River is getting higher and higher, but the dikes are getting less and less stable, and when it rains heavily, a yellow dragon swings its tail, and millions of people are poisoned.

Later generations have a song that says:

The rolling Yellow River is passing away in the east, the waves are sweeping away the fields, and the head is empty after a year of labor, and the Yellow River is still there, swinging its tail several times.

This is evident.

After listening to Fan Jingwen's explanation, Liu Hong gradually understood the real difficulty of the canal, the dam mouth!

As long as the construction of the dam mouth can be solved, the canal can benefit the people as soon as possible.

Liu Hongjian is not a person who sits idly by, God doesn't give face, so he earns it himself.

But how can the dam mouth be stabilized, reinforced concrete? This thing doesn't.

Wait a minute? No? Lao Tzu can make it!

Liu Hong gradually patted his head, he was really smart but was mistaken by cleverness, Lao Tzu came to Daming not to fight alone, not alone!

Thinking of this, Liu Hongjian ignored Chongzhen and Fan Jingwen by his side, and immediately took out a book from his waist like a trick - "The Foundation of Heavy Industry".

Under the surprised gaze of the two, they began to turn the pages of the book, page twenty-seven, the production process of cement!

"Found it! Your Majesty, Wechen has found a way to deal with it! Liu Hong was overjoyed.

It is no wonder that the manufacture of cement is ranked so high in the book, the foundation of heavy industry, and cement is the foundation of the foundation.

Chongzhen and Fan Jingwen looked surprised, and said in their hearts that this shaft wouldn't be crazy, just flip through a book and find a way to build a dam, so why do you need so many Hanlin?

There are thousands of people in the world who read books, which minister of the DPRK and the Central Committee has not read all the books, if there is a good way to deal with it in the book, how can those skilled craftsmen in the Ministry of Industry not know?

"Your Majesty, as long as this thing is developed, the dam mouth problem will not be a problem!" Liu Hong gradually saw that the two were stunned, and then swore and said.

"What kind of book is this? There are many typos, but can you still believe it? Chongzhen took the book and looked at it, only seven words of cement production process were written incorrectly, this thing can be believed, I believe you are a ghost, it's child's play!

"Specify the line, specify the line! If you don't believe it, I'll do it for you when I go back, and the minister is gone, and the minister is going to engage in black technology! "Liu Hong gradually discovered the new continent, where can he still care to explain the great use of cement to an uncle.

Facts speak louder than words, and when they are done, everything will be clear.

It's not just the dam that makes Liu Hongjian so excited, if this thing is made, plus the steel of the steel workshop, the steel bar can also be solved.

Doesn't that mean you don't have to live in a wooden house anymore?

In the past, I always felt that the steel jungle in the later generations was depressing, but in Daming, there are all-wooden houses everywhere, and I felt simple and elegant at first, and I felt bored when I looked at it.

Because of the load-bearing problem, the wooden house cannot be built too high, and the whole wooden material is extremely easy to cause fire, and once a fire occurs, it is often a street.

The reason is very simple, the whole street is full of wood, and when the wind blows, it is not a fire dragon dance!

This king wants to build the highest house in the Ming Dynasty, and he wants to be a real estate tycoon, build him ten, oh not a hundred real estate, and earn it 100 million.

Hahahaha! Liu Hong gradually went out of the palace like crazy.
