Zhu Youzhen took a deep breath and calmed his anger.

He carefully recalled the historical account of the invasion of Tsarist Russia.

Now at this time the problem is not big, the old Maozi came from distant Yakutsk.

That place is about 2,600 kilometers away from Jingshi and about 1,000 kilometers away from Shengjing.

Now it's cold and snowy, and the snow can bury the war horses, and Lao Maozi can't reach it at all.

For the time being, it is enough to clear the old Maozi of the stronghold, and as for the attack on Tsarist Russia, it is not yet time.

When the weather warms up next year, he will teach Tsarist Russia how to behave so that they will never dare to cross the Ural Mountains.

For the defense of Liaodong, Zhu Youzhen is still very relieved, with Yue Fei and the five thousand dragon teng army there, no matter how many hairs come to the fire, they are moths to fight the fire.

Zhu Youzhen walked out of the room after communicating with the system, and when he saw the emperor coming out, Meng Zhaoxiang stepped forward to give a salute:

"Your Majesty, can you elaborate on how to use the coal hammer you designed, the workers don't know how to use it."

"It's not that simple? Let me take a look. ”

Hearing that the workers didn't know how to use the coal hammer, Zhu Youzhen was very surprised, and walked towards the coal yard, and Meng Zhaoxiang Qinglong Aqing also followed quickly.

None of the coal workers, foremen, and managers could have imagined that the emperor would come to the coal yard and teach them how to make briquettes.

If they know about it, it is estimated that it will be enough for them to blow for three lifetimes.

In front of him, the anthracite coal had been piled up, and the outer layer had been frozen into ice coal, and Zhu Youzhen couldn't help frowning.

"Let the workers light more coals and put a large brazier at a distance."

"Obey"

There was certainly no shortage of coal in the coal yard, so Meng Zhaoxiang immediately asked the officials of the Ministry of Industry to inform the workers in the coal yard to prepare more braziers.

Soon, fires began to be lit all around the coal yard, first lighting the brazier charcoal, and putting some coal on it.

After the coal blocks are ignited by charcoal, the temperature of the coal yard begins to rise significantly, and the anthracite coal begins to thaw.

Seeing a worker holding a coal hammer to study over and over again, Zhu Youzhen went up to take over the coal hammer and wanted to demonstrate it to them.

But I immediately found out the problem again, there was a pile of dry coal underneath, how to operate this.

So Zhu Youzhen began to teach the workers how to make briquettes.

"You go and dig some loess, mix the loess with anthracite in a certain proportion and mix it evenly, only in this way can you make briquettes, and you can't form briquettes without loes......s briquettes."

This time, not only did the workers not understand, but even the officials of the Ministry of Industry were full of doubts.

Anthracite plus loess, can it be ignited? Now it's incredible to have to add water again.

"Don't doubt it, just do it right away."

Knowing that they couldn't understand it for the time being, Zhu Youzhen didn't want to explain more, a Ming emperor actually became a coal yard worker.

After Zhu Youzhen spoke, Meng Zhaoxiang saw that the workers were still standing still stunned, of course he was furious, even if what the emperor said was wrong, it should be implemented immediately.

He immediately called the official in charge of the coal yard and reprimanded:

"Didn't you hear Mr. speak? Execute it now! ”

"Oh, yes!"

There are many people who can work, and loess is everywhere, and soon a large pile of loess and anthracite is mixed by workers with water.

Zhu Youzhen picked up the coal hammer and hit it a few times on the coal pile, and the coal hammer was immediately filled with coal.

He stepped on a protruding iron rod above the coal miner, and immediately a round briquette with twelve holes fell out of the coal miner.

The workers' eyes widened and they shouted:

"Oh my God, it's so simple, we're so stupid, but can this ignite? There is so much loess in it, and it is still wet. ”

Zhu Youzhen smiled slightly:

"Of course, bring the coal stove."

"Yes"

The officials of the Ministry of Industry immediately asked the workers to bring a coal stove, and Zhu Youzhen put the honeycomb briquette on the carbon fire next to it, and handed the coal hammer to a worker.

"When you start working, do what I just did."

The workers immediately got busy, and when the briquettes were ignited, they made thousands of honeycomb coals.

Zhu Youzhen put the piece of honeycomb coal that had been ignited into the coal furnace, and then put another piece of honeycomb coal on it.

"When the next piece of honeycomb coal turns white, it means that the briquette has finished burning.

You have to take it out and put a piece on it, so that you can use it for heating, you can use it to boil water for cooking, and you can raise the temperature.

Seeing that the small round hole below is not there, plug it with a lid when not in use, which can delay the burning time of the briquettes, and when needed, just remove the cover from the hole. ”

Zhu Youjian taught the workers all the methods of making honeycomb coal and the use of coal stoves, and then left the coal yard and went directly to Changping.

It is not easy for the emperor to do it, especially the emperor who loves the people like a son.

Zhu Youzhen can also be regarded as a good emperor who loves the people like a son, and of course he can't let the people starve and freeze.

When I arrived at the farmland in Changping, the white greenhouses were almost completed.

Zhu Youzhen finally showed a smile on his face, it has been three days, and it took tens of thousands of people three days to turn 50,000 acres of fields into white greenhouses.

Looking at the white greenhouses that could not be seen at a glance, both the farmers and the soldiers were very happy.

They felt very warm standing in the greenhouse, not only did they not know where the materials in the greenhouse came from, but they also did not know what they were used for.

Zhu Youzhen never explained to them, but just asked them to do what the drawings required.

After entering the greenhouse, Meng Zhaoxiang seemed to suddenly wake up, and said to Zhu Youzhen excitedly:

"Oh my God, I understand, I understand, you can grow wheat here......"

"Yes, you can really grow wheat here, but the place is still too small......

There are a few farm officials who have come to study elsewhere and also feel the usefulness of the greenhouses.

Zhu Youzhen just looked at them lightly, and only he knew the bitterness in his heart.

This greenhouse used up more than 3 million points for him, how could it be as easy as these officials said, it was really not a family that didn't know that vegetables and rice were expensive.

After the construction of Dapeng was completed, Zhu Youzhen immediately transferred the farm and farmers to plough cattle, and the middle part of the land was ploughed with cattle, and the side was manually excavated.

In two days, all the fields were turned over, and the next work was to start planting sweet potatoes and potatoes.

30,000 acres of sweet potato fields have to be formed out of a series of raised ridges of about five inches, and the distance between the ridges is one and a half feet.

20,000 acres of potato land is directly leveled, and there is no need to have a high or low.

Another two days passed, and the sweet potato fields and potato fields were sorted out according to Zhu Youjian's requirements.

That night, Zhu Youzhen took Aqing, Cao Zhengchun, Qinglong and the royal guards to Changping together.

He wants to move sweet potato seeds and potato seeds from the system warehouse to the greenhouse, this kind of magical thing must not be known to outsiders.

As for Qinglong, they themselves are from the system, and Zhu Youzhen's secret is not a secret to them at all.

A group of people shuttled through the greenhouses like a marquee.

Every time he arrived at a greenhouse, as long as Zhu Youzhen waved his hand, those sweet potato seeds and potato seeds would suddenly appear.

There is no difficulty in the number of seeds needed, and the system has automatically calculated how many seeds are in a greenhouse.

Early the next morning, the soldiers and peasants came to the field where the greenhouse was located.

Seeing the piles of sweet potatoes and potatoes in the greenhouse, their eyes widened in surprise, and many farmers and farm officials who had grown sweet potatoes wanted to cry.

"Oh my God, after so many days of hard work, this thing has no production at all, so it's better to take it back and eat it now......"
