Zinu didn't know how important the new grain was, and what it would mean for generations.

She doesn't care about the yield of this grain, how it is grown, how much it ripens a year.

She only knew that she had helped Li Qinzai and solved the trouble for Li Qinzai, and that was enough.

Women, what do you need to do with so many national affairs? A man who can help himself is a good woman.

Zinu's idea is so simple and simple.

Outside the courtyard, the sound of horses' hooves stopped, Steward Song hurriedly greeted him, and Zinu stood in the courtyard, and couldn't help but be happy in her heart, she knew that Li Qinzai had rushed back from Chang'an.

So Zi Nu rushed up, came to Li Qinzai one step earlier than Steward Song, and threw himself into his arms.

Li Qinzai was hit by her and leaned back, and hurriedly reached out to hug her.

"With such enthusiasm in broad daylight, can't you wait for dark?" Li Qinzai said in surprise: "You sleep alone at night, leave me a door......"

"you!" Zi Nu blushed and pushed him, then his face was shy, and he raised his little face proudly: "I did something for you today, you hurry up and praise me!" ”

"Kua've got you!" Li Qinzai said without hesitation.

"Seriously, I really did something for you."

"I'm serious, I really praised you just now."

Zi Nu grinned, and her eyebrows fluttered as she said the process of interrogating Yin Duo just now, and she remembered every word Yin Duo said very clearly, and there was not a single mistake or omission.

As Zi Nu recounted, Li Qinzai's originally smiling face gradually became solemn, and finally his face was full of horror and shock.

"New World, South America......" Li Qinzai muttered to himself.

"What South America?"

Li Qinzai was still immersed in shock and muttered: "This is only the Tang Dynasty, has someone already been to South America?" The new grain species that Yin Duo said is clearly sweet potato......"

"Sweet potato? Is the new grain called sweet potato? You've never seen it, so how do you know it's called a sweet potato? "There are more and more problems with Zinu.

Li Qinjae didn't answer her, because he didn't know how to answer.

He has an answer, but it is an answer from a previous life.

The American continent is a continent blessed by God, where the products, fertile land, and unique and suitable climate are judged solely from the perspective of geography, products and climate, and I have to admit that the American continent is indeed much stronger than the Central Plains of the Tang Dynasty.

The people of Datang need it.

From the words relayed by Zinu, Li Qinzai determined that the new grain that Yin Duo said must be sweet potatoes.

Sweet potatoes were originally introduced to China after a thousand years of braided dynasties, but a businessman who hit by mistake and an incident by mistake made the wheel of history turn a corner.

It appeared on the land of Asia in advance, and was discovered by Lee Chin-jae, who knew the goods.

Sweet potatoes are also called sweet potatoes, yams, sweet potatoes, sweet potatoes, etc., there are many names, and the names of the north and south are different, but they all say the same thing.

More than 1,000 years later, whose child hasn't eaten a baked sweet potato on the street? It is not only the taste of childhood, but also the life charm of the people during the famine.

It is indeed a very high-yielding staple food, and it tastes pretty good.

If one acre of land is well served, the yield of sweet potatoes can be as high as more than 5,000 catties, and the south with a suitable climate can be harvested twice a year.

It is no exaggeration to say that it can really live millions of people, from generation to generation, so with one thing, there will be no famine in Datang, and the country's population will increase by a hundredfold.

The affairs of emperors through the ages, in the final analysis, are how to fill the stomachs of the people.

The people are not hungry, and the country is eternal.

If Li Qinzai can help Li Zhi solve this matter, his credit ...... Incredible.

"Well done!" Li Qinzai suddenly excitedly smacked on Zinu's face.

The subordinates next to them were stunned and hurriedly looked away.

Although Zinu is a little shy, his heart is even more sweet.

She is a foreign princess, full of exotic customs, and she will not be as timidly as a woman in the Central Plains, if she likes it, she likes it, she likes to be kissed by him, she likes to be kissed by him, and she doesn't care too much about the eyes of everyone.

"It's not enough to reward you with a hard dish tonight, or you'll eat me as a dish tonight?" Lee winked at her.

"Phew! I won't eat it, stinky man! Zinu happily refused.

Then Zi Nu asked happily: "Can the results of my question help you?" ”

"Of course it can help me, now I have determined that there is really a new grain seed, Yin Duo said it in detail, it is definitely not made up out of thin air, and half of the hanging heart is finally let go." Li Qinzai said happily.

Originally regarded as a big gamble, now Li Qinzai found that his chances of winning were getting bigger and bigger.

Zi Nu also smiled: "It's good if I can help you, if you can find new grain seeds in the end, ask your Son of Heaven to give you a big official." ”

Li Qinzai laughed twice, and then said: "The whereabouts of the new grain seeds, Yin Duo still refuses to say?" ”

Zi Nu suddenly said dejectedly: "He refuses to say whether he lives or dies, it is estimated that it is the secret of his life, and it is useless to torture, this person is obviously a greedy person who is afraid of death, and I don't know why he is particularly backbone." ”

Li Qinzai also said worriedly: "The only bargaining chip cannot be delivered easily, otherwise his life will not be guaranteed." No matter how greedy you are for life and afraid of death, I am afraid that you will grit your teeth and hold on. ”

Zi Nu looked at him and said, "Did you go to Chang'an because of Yin Duo and caused trouble?" ”

Li Qinzai smiled bitterly: "Yes, and the trouble is not small, it is estimated that it will be retaliated against by the Jingjiao soon." ”

Zi Nu said thoughtfully: "So, the key to solving this trouble is to find the whereabouts of the new grain seeds?" ”

"Yes, but Yin Duo won't say, I can't really kill him, who knows where he hid the new grain......"

Zi Nu was silent for a long time, and said slowly: "Yin Duo was rescued by me from Tocharo, and when I rescued him, the new grain seed should be on him, and I escorted him all the way from Tocharian to Chang'an, and he slept in the open on the way......

"The only possibility is that one day when Yin Duo was camping and camping, he left the new grain in some secret place while we were not paying attention, and if I returned from the same way, I would search every place where I had camped with my memory......"

Li Qinzai's eyes lit up, and then he shook his head with a wry smile: "This move is tantamount to looking for a needle in a haystack, you don't count on it." ”

Zi Nu was silent for a long time and nodded hesitantly.

…………

That night, Li Qinzai finally slept soundly.

Facts have proved that sweet potatoes do exist, and it has appeared on the Asian continent, and Li Qinzai's mood has relaxed a lot.

With hope and a goal, even if there is nothing to gain from Yin Duo this time, Li Qinzai has another way, which is nothing more than to spend more time and money.

In this life, there is a way to introduce sweet potatoes into Datang for planting, and in the next few decades, there will be a day when it will be successful.

Of course, the most worry-free thing is to find its whereabouts directly from Yin Duo, in one step.

Early the next morning, Li Qinzai was about to meet Yin Duo in person and try to ask about the whereabouts of the sweet potato, but Cui Jie hurriedly ran over and told him a piece of news.

Zinu was gone, and with more than ten of her entourage, she left the courtyard before dawn and disappeared.
