Champa rice, drought tolerant, adaptable, do not pick the field, the growth cycle is short, from sowing to harvest only more than 50 days.

If these characteristics are taken out alone, in fact, it does not necessarily make Champa rice so famous in history, but when the growth cycle, sowing date and other characteristics of Champa rice are combined with Chinese late rice, it produces a miracle that people can't refuse at all.

Twice a year!

For an agrarian society that revolves around the land, this is not even a miracle, but a miracle!

Twice cropping a year means that the annual output of a piece of land can be doubled, which means that the farmer's food ration can be doubled, and the rent and taxes paid can also be doubled. Whether it is for individuals, landlords or countries, this is naturally a great benefit. The Chinese population of the Song Dynasty could break through the 100 million mark, and it was also hailed as the richest dynasty in history.

And......

The grain output of two crops a year will also greatly accelerate the development of Jiangnan by the Central Plains Dynasty!

In the future, the southward shift of China's economic center will indeed be due to the fact that the Northern Song Dynasty was beaten into the Southern Song Dynasty by others, and the unenterprising imperial court was unwilling to return to the north, but the more important reason was the sharp increase in grain production in the south!

This is the best example of this in the Ming and Qing dynasties.

The beginning of the rapid increase in grain production in the south was the introduction of Champa rice to China during the Song Dynasty and its unprecedented popularity.

Therefore, for the big killer weapon that can almost change the course of history, since Li Yuanjia remembered it, he naturally had no reason to give up.

Now Datang is not interested in the south, on the one hand, naturally because of the "wealth of Guanzhong", on the other hand, it is also because the development of Jiangnan is not easy, and the hot climate and various forests are the biggest obstacles! And just with the current grain production, it is not worth spending too much effort to develop it......

To put it bluntly, he is bound to win the Champa rice.

Because as a person in the future, even if Li Yuanjia doesn't know much about agriculture, he still understands a little bit about history, and naturally knows how "untimely" it is for Champa rice to enter China, which is regrettable!

When the strength should be the strongest, I met the Song Dynasty!

Therefore, Li Yuanjia is also very curious, what if Champa rice could enter China in the Tang Dynasty? What kind of situation does an enterprising and open country create when it encounters an artifact that makes them explode in strength?

To be honest, that's pretty exciting.

What's the point of spending a thousand times for this? In fact, if you don't take into account the influence of all aspects, such as being easily attacked by the imperial history, there are ...... Ahem, if you are really a little distressed, Li Yuanjia really dares to come up with 10,000 yuan!

is still the same sentence, there must be a brave man under the heavy reward!

Even if the mountains are high and the road is far away, and the road is full of snakes, insects, tigers and leopards, as well as various "miasma" unique to the ancient south, but under the stimulation of 10,000 guan, 100% of people will break the kettle and organize a group of people to go to the south of Jiaozhi to find that legendary rice seed.

As long as you can get the rice seeds of Champa rice, what is one or two thousand yuan?

"If a thousand guan never attracts people, mention ten thousand!"

After pondering for a while, Li Yuanjia quickly made up his mind: "Anyway, even if this Zhancheng rice is found, it will definitely be dedicated to the imperial court and the second child in the future, and he will be reimbursed when the time comes...... Tsk, no! It's not enough to reimburse, at least 10 times the return, right? Let's make a hundred thousand dollars, just when I, the prince, have contributed to the Tang Dynasty, hehe! ”

The corners of his mouth curled, and Li Yuanjia laughed to himself.

If they directly told the emperor that there was a kind of rice that could make Jiangnan grow twice a year, Li Yuanjia really didn't have a full confidence that they would be completely convinced, after all, this thing sounded too mysterious...... No, it should be said that for the people of Datang, this is originally a fantasy. But he was 100% sure that once he found this rice seed, the emperor and the center of the Tang Dynasty would definitely put it on the altar immediately!

With food, who else will Datang be afraid of?

Enough food means a large number of people, if you add the "black technology" that Li Yuanjia took out, as long as his nephews and nephews don't die, these surrounding countries can still become disasters? For example, Tubo, which will invade Chang'an in the future, if Datang is really willing to spend time with it, will it be able to develop and grow in the future?

It is impossible for a male lord like Li Shimin not to see the huge role of Zhancheng rice, so let alone 100,000 guan, I'm afraid it is 1 million guan, as long as Li Yuanjia dares to ask for it, the emperor will definitely dare to give it!

Merely......

When the time comes, after taking the million, whether to continue to be a carefree prince, or whether to be sunk into Qujiang Pond by the second child one day, Li Yuanjia is not very sure.

So after laughing, Li Yuanjia had already secretly made up his mind: Don't mention the money or not, just give it to the emperor directly. Anyway, for him, the prince of the Tang Dynasty, the title is already respected, and Yulu is also the highest level, why do you want so much money?

If you offer Champa rice, you should add another halo to yourself to avoid death.

Thinking of this, Li Yuanjia didn't hesitate, and directly beckoned to Han Lucheng and said, "Forget it, I thought about it just now, you should send someone to Jiangnan Dao, and stay there in the future." ”

"Personally? What do you mean, my lord...... Just stay there for this rice seed? ”

After being stunned for a moment, Han Lucheng hurriedly asked carefully.

After listening to Li Yuanjia's explanation just now, why didn't he understand the importance of this rice seed? It's just that when he heard that the king said that he would send someone to Jiangnan Province and stay there all the time, Han Lucheng was still a little worried subconsciously.

After seeing his expression, Li Yuanjia raised his eyebrows and chuckled: "What, do you think there's anything wrong?" ”

"This ......"

After hesitating for a moment, Han Lucheng nodded seriously and said, "King, it's nothing to send someone to be stationed in Jiangnan, we already have thousands of acres of tea plantations over there...... But if he is asked to do this rice planting business, he will inevitably bring him a lot of money, in that case......"

Han Lucheng's words didn't continue, but Li Yuanjia already understood what he meant.

is based in Jiangnan, and it is definitely not possible to have less money for food, clothing and housing; Moreover, if you want to buy rice seeds from Zhancheng at a high price, you have to spend a lot of money to publicize this matter; Even in order to convince people of sincerity, they have to pay for some famous people to vouch.

These things are indispensable to spend money!

If such a large sum of money is handed over to someone and let him live in Jiangnan, can it be reassuring?

After thinking about it for a while, Li Yuanjia blinked his eyes and said helplessly: "Try to find loyal people, let the people over there in Jiangnan also watch ...... In addition, no matter who he is, if he finds rice seeds after going to Jiangnan, this king will reward him with a thousand yuan......"
