"This grass, did you really cultivate it yourself?"

The old patriarch looked at Yun Yi dumbfounded, and suddenly thought of the current crisis in the Evenki grassland, and immediately grabbed Yun Yi's hand again and said excitedly:

"Distinguished guests, this grass is very important to our Evenki tribe, as long as you are willing to give us this grass, we are willing to pay any price, even if you want half of the grassland, we are willing to give it to you!"

The old patriarch was so excited that even 'you' became 'you'.

"Old patriarch, don't get excited, listen to me slowly!"

Yun Yi stretched out his hand to appease the excited old patriarch, and then took a dark green and shiny grass road:

"Actually, this grass is not new to me, but a medicine that I have researched that can improve the genes of pasture, so that the grass grows in a way that is resistant to the natural pathological degradation of the pasture.

To put it more specifically, what kind of grassland will be degraded, not to mention the overgrazing places on the steppe outside, let's just say that the grassland of your Evenki, obviously the number of sheep raised is very small, but the grassland is still degrading, the most fundamental reason for this is that the nutrients in the soil suitable for the growth of pasture are slowly consumed by the pasture.

This consumption is not formed in one or two days, but in thousands, tens of thousands, hundreds of thousands of years, or even longer; Grasslands have been formed on this land for hundreds of thousands of millions of years, and these grasses continue to grow and absorb the unique nutrients in the soil; It's just strange that why these grasses have not degraded in millions of hundreds of thousands of years, but have degraded in these decades?

This is a degradation of the biological chain, which I have carefully studied and made the following hypothesis.

Before the advent of humans, the animals on the grasslands were diverse, such as sheep and horses after eating grass, and this nutrient was absorbed by them; After wolves and other animals eat them, nutrients are transferred to the wolf's body. And it changes so that this nutrient is returned to the soil in the manure.

This is a perfect biological chain system, even thousands of years after the emergence of human beings, this biological chain has always existed, only slightly destroyed by humans, which can also explain the reason why people have lived on this grassland for thousands of years, but the grassland has not had much problem.

Since the sixties, the peaceful environment has led to an explosion of population, which in turn has increased the demand for various resources; When it affected the grassland, there were more sheep. The degradation on the Hulunbuir grassland outside is this kind of overgrazing; Another evil consequence is that the wolf hunting activities that began in the 60s have almost completely disappeared in just a few years since the 60s.

The pasture began to degrade in the sixties, and the steppe wolf disappeared in the sixties, so I conducted research based on this phenomenon and tried to cultivate new pasture with wolf dung, and sure enough, I found that the forage cultivated by wolf dung grew very vigorously; So. Later, I carefully researched the ingredients in wolf manure and stumbled upon one ingredient that had the greatest impact on the pasture.

On the grasslands, I carefully analyzed the soils of many grasslands, and found that wherever the pasture grows well. There are a lot of such ingredients, and on the contrary, the grass grows poorly.

So, I understand, after the humans hunted the steppe wolf clean. It has an element in the manure that allows the grass to grow that can no longer be recycled, so that the soil contains less and less of this component.

This is the reason for the natural deterioration of the grassland! ”

The old patriarch and the wizard looked at Yun Yi's explanation in a daze. Although some places are obscure, I can be regarded as roughly understanding the meaning of Yunyi.

"Well, you mean, you found that element in the wolf dung, just sprinkle the wolf dung on the grass and make the grass flourish again?"

The old patriarch had a strange look in his eyes, and asked Yunyi tentatively.

"No, old patriarch, not with wolf dung, but with the element in wolf dung, I have extracted this element from other substances, as long as it is dissolved in water and sprinkled on the grass, it will soon make the grass vigorous again, and at least it can maintain a vigorous growth period for two years, and it will be sprinkled again after two years!"

Yunyi racked his brains to lie, and according to the characteristics of the space spring water that can only affect plants for two years, he deliberately explained that it can only maintain the effect for two years.

"Is this element very valuable, and how much would it take to make the entire grassland use this element?"

The old patriarch looked at Yun Yi tentatively and asked, at this time, the excited expression on his face had disappeared, and it was replaced by seriousness.

"It's not precious, but it's still a bit of a problem to use this grassland you belong to, it takes a lot of time to prepare to extract it, and the little element I carry on my body can only make a square kilometer of pasture grow again at most!"

Yun Yi smiled bitterly and nodded, he didn't dare, otherwise that lie of what element would definitely be a goof; This time, he planned to use the space spring water to make the one-square-kilometer grassland grow well, just so that Da Bai and his subordinates could eat enough; Then, after sending Yun Yan and the others to the university, he will come here again to help them solve this crisis, and also let them help him take care of Dabai and his subordinates.

"What, you have a lot of this element on you, which can make a grassland the size of a square kilometer grow well?"

The old patriarch and the wizard were shocked again, they never thought that Yun Yi had so many elements on his body.

"Hehe, don't be so surprised, although this element is very important, but the grass doesn't need much, a little bit is enough!"

As he spoke, Yun Yi held a small plastic bottle in his hand and said with a smile:

"There are not many elements in this small bottle, I mixed it with 100,000 catties of water, and then asked the young people in the tribe to sprinkle this water on an area of almost one square kilometer, it is estimated that it will not take a week for your grass to return to normal!"

Yunyi sprinkled too much water in the space in the sheepfold, so it grew very well, and he was not going to sprinkle too much water on the pasture here for the first time, so the contrast was too big and dangerous.

"And how expensive is this vial elemental?"

Old Ancestor asked suspiciously, and continued:

"Our exclusive grassland of Evenki is 30 kilometers long from east to west, 10 kilometers wide from north to south, 7 kilometers wide on average, with a total area of about 200 square kilometers. How much do you get in total? ”

"Hehe, two hundred bottles are enough, but although this element is cheap, it will take a little time, I can't take out so much now, wait until I go back and work for a while, and send this kind of thing again!"

Yun Yi smiled slightly, the reason why he said this was mainly to make the old patriarch think that the price of this kind of thing was indeed very cheap, so that he would not have to give himself money; And the trouble is mainly to make the old patriarch take care of their horses more carefully.

In doing so, the Evenki tribe took advantage of Yunyi, after all, Yunyi solved their survival crisis, and what they paid to Yunyi was just to take care of the horses, and it seemed that Yunyi suffered a big loss; But this is Yunyi's character, the Evenki tribe was very enthusiastic about Yunyi first, Yunyi didn't give them anything at first, they were in charge of eating and living, and they were always very polite, so Yunyi wanted to repay them like this.

"Distinguished guest, can you try these elements on a square kilometer playground tonight, please forgive me for my impatience, it is really because it is too important for us Evenki!"

The old patriarch looked at Yun Yi with a serious expression, slightly excited, but asked with some tentative in his eyes.

"Hehe, of course you can, but you should be careful at night, and don't tell my friends or your people, because I don't want to be famous!"

Yun Yi smiled, and once again reiterated what he didn't want others to pay attention to.

"Hey, hey, all the Evenki men, get up, get on your horses, bring your water bladders and buckets, and follow me!"

The old patriarch immediately stood up from the ground, and his short body suddenly burst out with a loud voice, so that everyone in the open space of the entire tribe heard his loud voice, and everyone quieted down, looking at the old patriarch with a serious face and waving his arms:

"All the boys, go quickly, don't ask what is going on, all the girls and women are here to keep a good look, take care of the guests who come from afar, and don't follow us, lest you desecrate the great immortal heaven!"

The old patriarch's prestige in the tribe was very high, although this order was a little confused, making everyone confused, but all the people in the tribe did it, the men immediately got up and galloped towards the yurt and the horses, the girls and women were all in place, away from Yun Yan and Ye Jian and the others to appease them.

"Brother, what are you going to do?"

Yun Yan and the eldest girl looked eagerly at Yun Yi who left here with the old patriarch and wizard, and they wanted to get up from the ground and follow them, but they were stopped by the girl beside them.

"Don't worry, Yan Yan, I have important things to do, don't worry about me, don't you think that the old patriarch is trying to rob money!"

Yun Yi waved at Yun Yan and the others with some amusement, signaling them not to worry.

"Please rest assured little girl, noble warrior Yunyi, there is absolutely no one who has any problems, and no one dares to force him!"

The wizard immediately walked over, bowed deeply at Yun Yan and the others, and then looked at Ye Jian, whose face sank, which made him stunned.

Yun Yan and the others finally stopped worrying, they naturally understood that the Evenki patriarch had no malicious intentions.

Soon, Yun Yi followed the patriarch and others to the vicinity of the small lake, and the old patriarch immediately asked people to dig a big pit not far from the lake, and then asked the men in the clan to start using big buckets to calculate and carry water inside. (To be continued......)
