At the beginning, the branches of the own merchant clan that Zhenning contacted, like Zhenning, wanted to swallow the trading of the bluestone collar and make a fortune in a muffled voice, but this kind of rare jasper jade, which originally only existed in the hands of cultivators, was suddenly sold in public batches, and all of a sudden the Nanwan merchants who got the news were stimulated and went crazy, and they came like flies that smelled blood.

Even if you want to stop it, you can't stop it, especially the leader of the bluestone collar, who only recognizes food and doesn't recognize people, which has caused several branches of the merchant clan to lose their monopoly advantage, but the general distributor of Zhenning has not been affected, but the price difference in Dafa Lishi has made a lot of money, and the branches that were originally high-spirited can't be suppressed.

For a while, thousands of sails gathered on the many waterways that connected the bluestone collar, and the floating on the water surface were all big ships from the ocean, and the river surface could hardly be seen as far as the eye could see, almost causing waterway traffic jams.

Of course, it is impossible to just load a few celadon vessels and go back with an empty warehouse, and the cabin will inevitably be filled with various Tiangong products and then return, which will greatly stimulate the productivity of the units under the name of the Tiangong Group.

The only thing that makes Gu Yi feel unhappy is that the main product of bluestone collar丨 is salt, but people don't want it, it's right to think about it, people come from the beach, and they won't lack salt if they lack anything.

It is in this situation that relieves the pressure of the bluestone collar food, all kinds of strange Nanyue food are transported into the granary of the bluestone collar, all of which are the "gifts" brought by the Nanwan merchant clan in order to buy celadon from the bluestone collar.

Although it sounds like a loss to have to give away a large amount of grain for free in order to get money to buy celadon, in fact, Nanyue, a ghost place called "Southern Wilderness" by the Taihua people in Zhongyou, is really a unique place with large grain production, and all kinds of high-yield grain should not be too cheap.

I heard that the natives there only need to sprinkle a handful of seeds in their lives, and their descendants within five generations can lie down in the grass nest and eat and sleep for a lifetime, so that those natives are very lazy, and they are not willing to harvest the grain that grows like weeds all over the mountains and fields when it comes to the harvest season, anyway, they will grow again when the seeds of the grain fall by themselves.

And the fleet of the Nanwan Shang clan, buying grain from the hands of those Southern Wasteland people, does not need to pay at all, only needs to give the local native leader an iron tool, and can be allowed to harvest the grain of a mountain, subject to filling the cabin, which means that you can take as much as you can, as long as you can transport it.

Of course, the premise is to do it yourself, the natives are too lazy to work, and they can't give money, and the gold cake can't be spent in their hellish place.

In this way, those Nanwan Shang clans do not need to pay any cost at all, and they can obtain a large amount of food, which is nothing more than consuming some transportation capacity.

And these grains are transported from a long distance, of course, it is best to sell them for money, and if they can't be sold, the right to go is a ballast stone, and it is not bad to use them in exchange for jasper jade, so naturally they don't care about sending food for nothing.

丨South Vietnam丨The grain-producing environment makes Gu Yi a jealous and hateful person at the same time, and at the same time, it is strange that no one wants to occupy it as a colony for Mao?

The Nanwan Shang clan brought grain, in exchange for celadon and the heavenly products they fancied, in Gu Yi's opinion, it was already a terrible high price, but there was no problem for them at all, and if they didn't sell it for more than five times the profit, they were embarrassed to call themselves Nanwan Shang clan.

This not only relieves the food pressure of the bluestone collar, but also meets the shopping needs of the Wan merchants, as for how much they take these goods back and sell, Gu Yi doesn't care, everyone earns money, hello, I am good, he is good, each eats according to his ability.

In this case, the food crisis problem of Qingshi Ling丨 has been temporarily alleviated, as long as we maintain a good trading relationship with the Wan merchants, I believe that we will not worry about food in a short time.

However, once the food thing is stuck in someone else's hand, it is as dangerous as your own finch being tied with a rope and playing, and no one knows when someone will pull your life off as soon as they exert themselves.

Therefore, when the food problem was solved and began to recruit a large number of people openly, Gu Yi began to think about how to develop agriculture while developing industry.

This can't blame them for taking the 1,000 yuan monthly salary of the Tiangong Group in vain, those famous craftsmen in the agricultural field, when they came to the bluestone collar, it was a cold winter, useless, they could only be very depressed nested in the old nest, studying some of the animal husbandry and mulberry content in the "Tiangong Kaiwu: Nai Grain Volume" and "Qi Min Yaoshu" given to them, watching the "Tianji Twelve Pavilions" The masters of the same sect and sect are busy in full swing, and they are about to go crazy.

Finally, when the winter went to spring, Gu Yi, the "chief engineer" of Tiangongmen, was busy with the Great Leap Forward, directly delaying the best season of spring ploughing, and they were about to vomit blood, and they were clamoring to "run away from home" one by one, that is, to quit Tiangongmen丨 and go back to their original sect, it is better than staying in the bluestone collar and not being taken seriously.

Gu Yi, who was busy and anxious, could take care of it so comprehensively for a while, to be honest, if it wasn't for Zhen Ning looking for him desperately, he wouldn't have remembered this, and finally used the "Technical Confidentiality Agreement" signed by the famous craftsmen to threaten these famous agricultural craftsmen who had already read the agricultural chapters of "Tiangong Kaiwu" and "Qi Min Yaoshu" to stay, and then hurriedly find some work for these idle masters.

Due to missing the spring ploughing, Gu Yi originally planned to plant the four-season rice in full swing, but the first season was obviously too late, and it was too late to reclaim the paddy fields, so he could only find a batch of crops that could be planted first.

Gu Yi asked the Wan merchant fleet to help him collect all kinds of plants and animals from all over the country while transporting grain, regardless of whether he could eat it or not, as long as he had never seen it, he would get some back to him, and he wanted to try his luck to see if he could find high-yield crops such as corn, potatoes, and sweet potatoes.

In order to cultivate these plants, Gu Yi also specially opened up a vast area of the Ten Thousand Plant Garden, and then threw those idle lice catchers and famous craftsmen into it, and let them study the characteristics of animals and plants, as well as the advantages and disadvantages of these animals and plants, and classify them, which can be regarded as the first batch of botanists and botanists to be trained for Tiangongmen.

Coincidentally, Gu Yi really found a crop that is more suitable for the current situation than the four seasons rice than the four seasons rice, and after inquiring about the growth environment and characteristics of this thing from the Nanwan Shang people, he immediately made a decision to plant this thing called "green vine cassava".

According to Wan Shang, who brought this thing, "green vine cassava", a perennial cucurbitaceous plant that looks like a watermelon vine, has extremely developed rhizomes, and one plant can cover ten square meters of land.

Moreover, this "green vine cassava" grows very fast, as long as there is moisture and a little dirt, it can spread wildly, and the growth time is very short, but the survival time can be as long as decades

I heard that the people of the Southern Wilderness don't eat this thing, and they will even pull out the rhizomes that are as thick as an arm, dozens of feet long, pile them together and use them as firewood.

The sailors on the merchant ship broke open the rhizomes that looked like the roots of the trees and tasted them, only to find that although they had no taste, they could be eaten, but the taste was slightly astringent.

Gu Yi asked Na Wanshang very curiously at that time: Since this thing can be eaten quickly and quickly, why would the people of the Southern Wasteland not eat them?

That Wanshang looked at Gu Yi like a fool: the people of the Southern Wasteland didn't even bother to harvest the big spikes that grew all year round on the mountain, who would go to the trouble to dig up these things that were buried in the soil and were not tasty?

Gu Yi immediately sweated, and asked again: Why don't you transplant this plant back and plant it in a place where there is a shortage of food?

That Wanshang told the truth, it turns out that although this kind of green vine cassava grows fast, but there is a place where it grows, it is extremely soil-intensive, and other plants cannot grow, and it is difficult to completely die once it grows.

To say that it can live for decades does not mean that it will die after a few decades, but because it "starve" to death after exhausting the soil around the place where it grew and no longer able to absorb a little nutrients and water

And even if the green vine cassava dies, no other plants will grow in the place where it has grown in a short time, and it will gradually become barren and desertified, and eventually form a dead desert.

The reason why those people in the southern wilderness found this kind of green vine cassava would pull them out and dry them as firewood, not simply because they were too lazy to chop firewood, but to prevent their hometown from becoming a barren desert.

Gu Yi broke out in a cold sweat when he heard this, isn't such a domineering thing just a dangerous and aggressive plant?

Although I have not been able to find potatoes, sweet potatoes and other high-yield crops, but this should be a close relative of the cassa green vine cassava, not only strong vitality, fast growth, high yield, but also cold-resistant, heat-resistant, drought-resistant, waterlogging-resistant, aggressive, no pests and diseases, can be said to be the most suitable for the current development of the crop.

As for the planting method of this thing, it is even simpler, as long as the rhizome with fibrous roots is cut into a few inches of small sections, and buried in the soil according to the density of a tree within a radius of thirty thousands, there is no need to care about it at all, at most in a month, it can grow ten square circles, that is, nearly an acre of land on the surface and underground
