It's just that Yunlan remembers that when he was in history class at school in the past, the teacher gave them the history of planting science on a whim.

It is said that the history of cultivation can be traced back to the origins of mankind, and many cultivation techniques have long since been lost over the years.

The plants that once provided people with a full stomach have also changed over time, and their genes have continued to mutate and become difficult to swallow.

Nowadays, people have long ceased to rely on those plants to satisfy their stomachs, and more convenient, faster and more delicious nutrients have become a new source of food for human beings.

Of course, this is not to say that the crops that once existed as food are not necessary.

Now the Commonwealth Crop Seeds, like the planet, are strictly divided into five classes.

I heard that the highest grade S grade seeds have the least genetic changes, and the taste is also the closest to the long history, and the original taste of those crops is very different from the lowest grade D grade seeds.

Many of today's self-proclaimed families in the Federation disdain to eat such things as nutrients, but maintain the tradition of eating natural crops.

Of course, they eat crops grown from S-grade seeds, and the price is sky-high.

In Canglanxing, Uncle Luo and the others planted D-grade seeds, which can be eaten, but they are only edible, and the taste is far worse than the cheapest nutrients.

But it's something she's grown from a snack to a big one.

She wanted to learn planting from Uncle Luo, but she didn't plan to plant D-grade seeds.

The D-grade varieties are not only unpalatable, but also have no nutrition, the only function is to fill the stomach, and they cannot be sold at all, and no one will buy D-grade crops.

She'll need to grow some crops that earn Star Coins.

The poison gas in Canglan Star has intensified a lot in recent years, and if conditions permit, she wants to buy a protective shield for the village that can filter the poison gas, so that Uncle Luo and their old age will not be so painful.

But the star coins she saved in the four years of studying in Moran Star were only enough to buy some B-grade seeds, and no matter how high they were, they didn't dare to think about it.

[Grade B species? You're going to plant a B-class seed on Star 1256? Can you grow live? Yao Qiu's question mark is three times in a row.

It's not that she strikes Yunlan, the more advanced the seed, the more delicate it is, and the higher the requirements for the living environment.

For example, S-class seeds can only survive if they are planted on A-class and S-class planets.

The level of the B-grade species is neither high nor low, the vitality of the seeds can be called tenacious, and the taste is passable, but the No. 1256 star is a garbage star, and people can't live without an antidote on it, so can the B-grade seed survive?

[I'll buy some more land purifiers and crop nutrients to try.] Yunlan replied.

She didn't know if she could grow a living, but she had to try, and she really couldn't think of any way to generate income.

Because crops will consume land fertility, cause the loss of land nutrients, and affect the ecological environment, land purification agents and crop nutrients are widely used in the Federation, and these two agents are also sold cheaply.

At least it's cheaper than the nutrients that people eat.

[Okay, I'll help you see, and tell me if you have any difficulties.] 】

Yao Qiu couldn't think of any way to help Yunlan in a timely and effective manner, so he didn't say anything more.

In fact, whether it is seeds or land purifiers, they are sold on the Star Network, but these purifiers are good to say, the quality is very different, and the price is cheap.

The seeds are different, they are also B-grade species, and there are also differences in quality.

At the same price, picking the best B-grade varieties by yourself, even if you add the cost of express delivery, is better than buying the most inferior B-grade varieties on the Star Network.

With Yao Qiu's help, Yunlan was no longer entangled in the ethereal spiritual weapon, and concentrated on studying the cultivation of crops.

After following Uncle Luo for two days, Yunlan only felt that it was more difficult to grow crops than for her to learn mecha design and maintenance.

"Well, don't make a mess with me, just play around."

After tossing for another two days, Uncle Luo's temper became impatient.

Look at how many seedlings he has trampled to death.

Yun Lan was embarrassed to take a few steps back, and in the process, he stepped on a few green seedlings, and Uncle Luo, who was watching, twitched in his heart.

"Lan girl, what do you want to do?" Uncle Luo put down the hoe, straightened up, and asked tiredly.

Yunlan lowered his head, his fingers constantly tangled in front of him, "That's it, just follow you to learn how to grow these crops." ”

Uncle Luo sighed, "You've decided?" There is no hope on Moranxing's side? ”

In fact, on the day this girl came back, the uncles and aunts who watched her grow up since she was a child probably knew it in their hearts.

Now is the time when Yun Lan is about to graduate, if Yun Lan's application to stay in Mo Lanxing goes well, she will not return to Azure Star at this time.

But now that she's back, it means that things have changed, and she probably won't be able to stay in Moran as expected.

Yun Lan fingers paused, and after a while, his voice choked slightly.

Wiping the dirt off his body, Uncle Luo patted Yunlan's shoulder and comforted: "It's okay, our Blue Star is also very good, and we won't die of hunger when we come back." ”

In the end, she watched the child grow up, presumably she suffered a lot in order to stay in Mo Lanxing, how could they bear to blame her.

A tear dripped on the dry ground under his feet, Yunlan sniffed and nodded, "Well, Uncle Luo, I will learn how to plant with you!" ”

Uncle Luo: "······"

Looking at the small piece of green seedlings that were trampled to death under his feet, he couldn't say a good word.

After sacrificing an unknown number of green seedlings, Uncle Luo finally couldn't bear to drive Yunlan away.

"Your injury is not healed yet, you can't work too hard, you go back to rest today, and come back to study tomorrow."

Yun Lan was very self-aware and did not continue to pester Luo Yu, and returned to the room to look at the dirty mountains outside the window in a daze.

She doesn't seem to be very talented in planting, so she won't have all the money to buy B-grade seeds, right?

When I was doubting myself, the light brain showed that there was a goods to sign.

Yun Lan took two steps back, clicked receive, and a delicate box landed in front of her.

Before he could open it and take a look, Yao Qiu's news came.

[The seeds are bought for you and sent over, you can see how the quality is. 】

Yunlan opened the box, which contained three small bags of seeds, each with a sticky note on it, indicating what kind of seed it was.

The number of seeds in the bag is not much, only a dozen or so, but looking at the quality of the seeds, they are all full and moist, and they are obviously all B-grade seeds with the best quality.

[The seed quality is very good, how much does it cost, I will transfer it to you?] These three bags of B-grade seeds, I'm afraid it will cost a lot of money.

[It didn't cost much, I have a friend who has a channel at home, and he sold it to me at cost price, so you don't need to transfer money to me, and when the crop is ripe, you can send me a little to taste. 】

Yunlan knew Yao Qiu's temperament, she said that she didn't want money, if she had to give it, she was afraid that she would be angry.

It's just that the cost price is still B-grade, and the cost price is not cheap.

No, Yunlan had to say: [Okay, when the planting comes out, I'll send you some to try it when the time comes.] 】

If she can grow it at all.
