"Hungry. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ”

Lu Yu stretched out a finger.

He says a question and then sums it up in one word.

That's right.

The Great Chief was stunned for a while, and then said with a bitter face, "It's really ...... This question. If they are all fed, why do they need to compete for any territory? If they are all well fed, what kind of hunters do they need to rob? Even the wars that extend from these are irrelevant. Ay...... I know that some tribes are clamoring for war all day long, but in fact, there are too many people in the prime of life, and there is not enough food to eat...... That's to send them to death on the battlefield. ”

Lu Yu nodded and said: "You can see this point clearly, so the future of the barbarian race is actually just like this." ”

He pointed to the small cloth bag in the big chief's hand and said, "This is the answer, and it is the only answer I can think of so far, what you barbarians can do." ”

"This ...... That's it?!"

The Great Chief's hand shook again, and he almost knocked off the small cloth bag again.

"What the hell is this?"

Lu Yu laughed and said: "Some people used to name it sweet potato, and they also said white potato, but I always think it doesn't sound good." ”

"White ...... White potato?"

The Great Chief looked inside the bag with a frown, then muttered, "Also...... It's not white......"

One sentence almost made Lu Yu laugh.

White potato, also known as sweet potato.

The word 'fan' is very important, in the last life, this thing was not native to the land of the Celestial Empire, but was 'imported' from abroad, so there is the word 'fan', which directly refers to the meaning of 'Fanbang'.

It's too common, it's too familiar, so people have long ignored its greatness.

That's right, it's greatness.

It is the most important crop in the world, and it is also the crop that has the greatest impact on the Celestial Empire, and it is not an exaggeration to describe it with the words 'changing the heavens and the earth'.

Adaptable to the environment, high yield, easy to care for...... and so on, so that it brought a miracle to the Celestial Empire.

In fact, before the sweet potato, only two or three hundred million people could survive on the huge land of the Celestial Empire, which was very different from Lu Yu's era of hundreds of millions of people.

As for the reason, the root cause is that there is not enough food to eat. All the land is planted with food, and it is only enough for so many people to eat, and a few more people will not have enough food.

Therefore, whenever the society has been stable for a period of time, there will inevitably be wars on this land, and many people will die in wars.

Why? Because with stability, the population will grow rapidly, and when the food of the whole world will not satisfy the whole world's long diet...... Someone is hungry, and when he is hungry, he will be beaten. What a simple truth.

All the reasons are secondary reasons, and the main reason is that food cannot feed people.

And sweet potatoes are coming.

The population of the Celestial Empire has reached five or six hundred million, or even six or seven hundred million, in just a few decades!

It's such an amazing crop.

In the face of today's barbarians, this sweet potato is even more ...... 'magical'.

The barbarians don't know how to farm, and even if they do, it's still excellent land, and if they are careless, the yield is not very high, and it is difficult to feed themselves, let alone sell anything.

Secondly, the land of the barbarians is really too unsuitable for farming, the cloudy and sunny forest, and the endless Gobi.

But the land of the barbarians has one advantage, that is, there is no desert, the kind of desert that can eat people.

And except for that kind of desert...... Sweet potatoes can grow!

The main thing, the barbarian region, did not change much in temperature.

If this was placed in the world of Lu Yu's previous life, this would definitely be a treasure land! Unfortunately, this world is too backward. As Lu Yu once said, the development of cultivation will lead to the backwardness of science and technology, because ...... I really don't need it.

As for this 'sweet potato', it is actually not the sweet potato that Lu Yu knew in his previous life, there are still some differences, but they are 'good' differences.

Its flavor is between sweet potato and taro, and the flesh is slightly sticky and heavy. However, the ability to adapt to the environment is much higher, as if everything in this world is stronger, even ordinary crops are more 'combative'.

Originally, the growth cycle of sweet potatoes was short, which is also the root of its 'super crop', in previous lives, most people chose to have a wave of sweet potatoes before the main crop was cultivated, and then planted other ones after it had a harvest, which is a race against time, and can really squeeze out.

In two or three months, it only takes so long from sowing to harvesting, and it can also stagger the most suitable growth period for other crops.

It's amazing.

The so-called 'sweet potato' here only takes one and a half months to grow!

For more than forty days, sowing and harvesting, it was verified by Lu Yu himself.

To be honest, the first time he saw it, ate it, and then tried to cultivate it, at the time of harvest, Lu Yu himself was shocked.

This thing can completely become his huge hole card, a gold medal, which can change many things at the most critical moment, and even save his life.

But...... Unfortunately, this hole card can only be used once. Cool xf craftsman v# net d~ first ^ hair ("

As long as it is grown, sold, then ...... Regardless of whether Lu Yu hid his own secrets or taught the cultivation method to others, others could always find the cultivation method by themselves, or do it through various experiments, or ...... It's just that the unlucky guy lost it, threw it in the ground, and then two months later found that there was a crop there, and pulled out a whole lot of sweet potatoes......

Whether intentionally or unintentionally, people can always learn how to cultivate it on their own.

So this is something that cannot be monopolized, and it can only earn the only pot of gold at the very beginning.

So how much money to get in this first pot of gold, Lu Yu has actually been hesitating.

Now...... But there is no need to think about it anymore, after all, he has promised the barbarians, so take it out directly, and Lu Yu will not regret anything carefully.

"This thing," Lu Yu walked over, stood in front of the big chief, and said softly: "It needs to be cut into pieces first, and then buried in the soil, into the soil for three points, not deep or shallow, pressed soil three stones, can not be heavy or light, in the water supply three scoops, there can be no slightest error, each plant is three feet before and after, see the earth square." Wait only ten days, then remove the weeds, loosen the soil, and then ten days, water every day, as much as the right amount, another ten days, deworm and clean up, there can be no slack, wait for another ten days, burn incense and sacrifice, and finally ten days, uproot it, and then ...... I promise you'll be smiling from ear to ear, and you'll understand why I'm saying they're the future of your barbarians. ”

The Great Chief listened carefully, remembered carefully, then raised his head and asked a little tangled, "This...... Do you still call it a sweet potato? The name is a bit ......."

Lu Yu rolled his eyes, he didn't expect that the other party was most worried about such a name, but after thinking about it carefully, he was also a little relieved, it seems that the previous ceremony had made the big chief understand something.

Lu Yu thought carefully for a while, then turned his head to look at the blackbird perched proudly in the distance, and said with a smile: "Let's call it Phoenix Grass." ”
