Datang: Acting as a celestial mystery at the beginning

"Sir, why do you say that?" Li Shimin asked.

"Next spring, there will be a severe drought in Hebei and a drought in Shandong in summer. At that time, the imperial court will need a lot of food for disaster relief. If we prepare more food now, we can save more people who may starve to death." Li Yi'an explained.

"Will there be a drought next year?"

Li Shimin was surprised: "Sir, what you said is true?"

Li Yi'an nodded slightly while drinking tea.

Mr.'s words have never been miscalculated, and he is right about what he says.

Li Shimin pondered for a moment, then suddenly became nervous. Next year, he plans to change his reign name to Zhenguan. If natural disasters and man-made disasters happen, it is not a good omen, and some people will even say that he is not suitable to be the emperor.

He would have been under a lot of pressure if he hadn't been reminded by Mr.

Li Shimin said: "Fortunately, I came to see you today, otherwise the people of Tang Dynasty would have to suffer, but with your ability, sir, can you reverse the drought?"

Li Yi'an couldn't help laughing and said: "Mr. Do you really think that I am a fairy? If you say let the sky rain, it will really rain. It's just that I can't reverse the drought, but I know there is one thing that can Increase food production, even if there is a drought in the future, the people will not be unable to drink porridge, and it will allow the people to have food at home."

"Really?"

Li Shimin immediately stood up: "Please enlighten me, sir!"

The world is based on agriculture, the people can have enough to eat, and the army can have sufficient food and pay, all relying on agriculture.

If there is a drought or a plague of locusts, the agriculture will be devastated, the people will die from starvation, the army will lack food and pay, and even national defense will become a problem.

Most of the farming in the world is monopolized by aristocratic families. When disasters happen, it is only ordinary farmers who suffer. The aristocratic families are so rich that they have no shortage of food, but they will never provide food for disaster relief.

"In the land of Nanman, to the south of Jiaozhou, there is a country called Linyi. During the Daye period, Liu Fang was conquered by the Sui Dynasty. Later, there was turmoil at the end of the Sui Dynasty, and they made themselves kings. There is a place in the country called Zhancheng, which is rich in a kind of rice. , called Zhancheng rice, high-yield, early-maturing, and cold-resistant!"

According to the memory of later generations, Li Yi'an continued: "This kind of Zhancheng rice is grown in any place, not picky about the soil, and has a short growth cycle. It only takes about fifty days from planting to harvesting. The yield is relatively high, with an yield of two per mu. stone."

When other people travel through time, the system either gives potatoes or sweet potatoes, or corn.

Li Yi'an's broken system only provides various planting techniques, not real objects and seeds. He has no choice but to find out the high-yield crops that exist in Asia to solve the food problem.

One stone in the Tang Dynasty was about 120 catties, and the yield of two stones per mu was 240 catties. Compared with potatoes, it was not a high-yield crop at all, but compared with local crops, it was definitely high-yield. The most important thing The thing is to mature quickly.

According to the "New Tang Book", the yield of crops in the Tang Dynasty was about one stone per mu, and the yield of good fields in Gyeonggi was nearly two stones, and Champa rice was directly doubled.

Champa rice was only introduced to China during the Northern Song Dynasty, and it was popularized in the Jiangnan area, which made it famous in the Song Dynasty as "cooked in the south of the Yangtze River, and the world is full".

"If someone goes to Champa in Linyi Kingdom and brings back the seeds of Champa rice to cultivate, in a few years, most of them will see a bumper harvest, which can greatly alleviate the food problem." Li Yi'an continued.

"Really, really?"

Sir is great!

In the south of Jiaozhou, as far away as Linyi, he also knew it so clearly.

Li Shimin seemed to be able to see that the people of the Tang Dynasty had ample food and clothing, and said excitedly: "After returning, I will immediately order people to go south to Linyi to occupy the city."

Li Yi'an said: "Don't worry, I still have two good things that can be of help."

After finishing speaking, he went back to the house, took out a pen and paper, and drew sketches one by one based on the knowledge passed down by the system.

"Sir, are you a plow?"

Li Shimin looked at one of the sketches and found it very familiar.

"That's right, this is my recently improved plow. I call it Quyuan plow. Compared with ordinary plows, I have made these changes..."

Li Yi'an gave a brief introduction: "Ordinary plows are very heavy and difficult to use. My curved plow only needs an ox and can be used by one person. It can also adapt to various soils. It is very convenient to use and easy to cultivate. The speed is more than double that of ordinary plows."

After hearing these explanations, Li Shimin's eyes shone brightly.

Labor is definitely a big problem for farmers to cultivate. Many farmers in the village do not have cattle or lack cattle. The cattle in the village cannot be guaranteed to be used by everyone, and Lizheng cannot coordinate.

In terms of farming, if there are not enough oxen, there is no way to use a plow. It can only be cultivated manually, which is extremely inefficient and requires a lot of labor.

This curved shaft plow can be pulled by only one ox. In the future, farmers' cattle can be better allocated and used, and their farming capacity will be greatly improved.

An artifact, another artifact of a powerful country.

You never know what kind of magic weapon Mister will come up with.

Li Shimin was thinking in his heart that getting to know Mr. was the most correct choice since he became emperor.

"Sir, what is this?"

Li Shimin suppressed the excitement in his heart and pointed to another sketch.

"This is a leak hoe, which is slightly smaller and lighter than ordinary hoe. It is suitable for loosening soil and weeding in dry land in northern areas. It is just right at this time."

Li Yi'an's thing comes from "Heavenly Creation". Besides, there are other agricultural tools, but they are not given out all at once.

He needs the experience of mastering the craftsman template of a big country, and cooperates with Li Langjun to promote some industrial and agricultural tools and affect more peasants. The experience will be improved quickly.

However, this matter is not in a hurry, and we have to take our time in the future.

Upon hearing this, Li Shimin solemnly put away the two blueprints, continued to suppress the excitement in his heart, and cupped his hands and said, "Thank you for your enlightenment, sir. If you have no other orders, I'll go back and ask people to buy grain, and then go to Champa rice." , and to promote these agricultural tools.”

He couldn't wait, he wanted to go back and test whether the things given by the husband worked.

With Li Yi'an's nod, he hurriedly left Wannian County.

However, after returning to Taiji Palace, Li Shimin felt that the most urgent issue at present was the drought in the coming year.

"Mr. said that there will be a severe drought in the new year. I don't know if the result calculated by Yuan Tianshi is the same?"

Li Shimin felt that it was better to be more stable, because the imperial court's large-scale purchase of grain would lead to an increase in grain prices to some extent.

Before the drought comes, food prices will rise, and the impact will not be very good.

-

Qin Tianjian.

Yuan Tiangang didn't bother Li Yi'an after he asked about the Dao of Heaven last time, but he still couldn't forget about the Dao of Heaven.

Now that the weather is getting colder and colder, Yuan Tiangang heated up a small stove in Qin Tianjian, and some wine was warmed on the stove.

This is a newly brewed wine that has not been filtered, and green scum appears on the surface, as small as ants.

Green Ant New Distillery, red clay small stove.

It's not the season of winter yet, it's not the time for snow, otherwise it will be more artistic when there is snow.

Even so, Yuan Tiangang enjoyed the good wine, and his small life was very nourishing. After all, Qin Tianjian didn't have many things to do. Observing the sky, formulating the calendar and other things were done by the people below.

His part is all done.

"Tianshi Yuan is very elegant!"

Li Shimin walked in slowly and said in admiration.

"Your Majesty, why are you here?"

Although Yuan Tiangang was slightly drunk, he was still a little sober and jumped up quickly.

Regarding his drinking in Qin Tianjian, Li Shimin didn't care about anything with him, and said: "I came to find Tianshi Yuan, I want Tianshi to calculate, next spring and summer, what will happen to the sky, will it be drought or flood, or will the weather be good? "

It was this thing.

Yuan Tiangang had already finished it, and said with a smile: "For the matter of celestial phenomena, I wrote a memorial this afternoon and sent it to my family. I can be sure that next spring and summer, the Tang Dynasty will have smooth weather and clear skies."

This is not the same as what Mr. said!

"Tianshi Yuan, are all your calculations true?"

Li Shimin still believed in Mr. Yuan, and felt that Yuan Tianshi was a bit unreliable.

"I can swear to God!"

Yuan Tiangang, who was slightly drunk, didn't know that something was wrong with what he said. He just felt that His Majesty didn't trust him, and continued: "If I have half a lie, God will beat me..."

Rumble!

Before Yuan Tiangang could finish his sentence, there was a thunderstorm in the sky, and the lightning struck ferociously, as if the heavens were angry.
