It’s just that Yunlan remembered that when they were taking history classes at school, the teacher once taught them the history of implantology on a whim.

It is said that the history of planting can be traced back to the origin of mankind, but now in the long river of time, many planting techniques have long been lost.

Those plants that once provided people with full stomachs have also changed over time, their genes have continued to mutate, and they have become unpalatable.

Nowadays, people no longer rely on those plants to satisfy their hunger. More convenient, faster and more delicious nutrients have become a new food source for mankind.

Of course, this does not mean that crops that once existed as food no longer have a need to exist.

Now, the crop seeds of the Federation are strictly divided into five levels, just like the planet.

I heard that the highest-grade S-grade seeds have the least genetic changes and their taste is the closest to the original taste of those crops throughout history. There is a huge difference between the lowest-grade D-grade seeds.

Nowadays, many families in the Federation who pride themselves on being stylish disdain to take nutritional supplements, and instead maintain the tradition of eating natural crops.

Of course, what they eat are crops grown from S-level seeds, and the prices are sky-high.

On Blue Star, Uncle Luo and the others grow D-grade species, which are edible, but only edible, and the taste is far worse than the cheapest nutritional supplements.

But this is something she has grown up with.

She wanted to learn planting from Uncle Luo, but she had no intention of planting D-level species.

D-grade crops not only taste terrible, but also have no nutrition. Their only function is to fill the stomach. They cannot be sold at all, and no one will buy D-grade crops.

She needs to grow some crops that can earn star coins.

The poisonous gas on the Blue Star has become much more severe in recent years. If conditions permit, she would like to buy a protective shield for the village that can filter the poisonous gas, so that Uncle Luo and the others will have less pain in their later years.

But the star coins she saved during four years of studying at Moran Star were only enough to buy some B-level seeds, but she didn't dare to think about higher ones.

[B-level species? Do you want to plant B-level species on star 1256? Can it survive?] Yao Qiu asked three questions in a row.

It’s not that she attacked Yunlan. The higher-grade seeds are more delicate and have higher requirements on the living environment.

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

The level of B-level species is neither high nor low. The vitality of the seeds can be said to be tenacious and the taste is not bad. However, Star 1256 is a garbage star. People cannot survive on it without an antidote. Can B-level species survive?

[I’ll buy some more land purifiers and crop nutrients to try.] Yun Lan replied.

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

Because crops will consume land fertility, cause land nutrient loss, and affect the ecological environment, land purifiers and crop nutrients are widely used in the federal government, and these two agents are also sold very cheaply.

At least it's cheaper than nutritional supplements taken by humans.

[Okay, let me go and help you. If you have any difficulties, just tell me. 】

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

In fact, whether it is seeds or land purifiers, they are all sold on Xingwang. But the purifiers are of good quality, and the prices are cheap.

Seeds are different. They are both B-level species, but there are differences in quality.

At the same price, choosing the best B-grade varieties yourself, even if you add the cost of express delivery, is better than buying the inferior B-grade varieties on Xingwang.

With Yao Qiu's help, Yunlan stopped worrying about illusory spiritual weapons and concentrated on studying the cultivation of crops.

After following Uncle Luo for two days, Yunlan felt that growing crops was more difficult than learning how to design and maintain mechas.

"Hey, don't make trouble with me and go have some fun."

After struggling for another two days, Uncle Luo became impatient no matter how good his temper was.

Just look at how many of his seedlings were trampled to death.

Yunlan took a few steps back in embarrassment, trampling several young sprouts to death in the process, which made Uncle Luo's heart tremble.

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

Yunlan lowered his head and kept intertwining his fingers in front of him, "I'll just follow you and learn how to grow these crops."

Uncle Luo sighed, "Have you decided? Is there no hope for Mo Lanxing?"

In fact, the day this girl came back, they, the uncles and aunts who had watched her grow up, probably knew it in their hearts.

Now is when Yun Lan is about to graduate. If Yun Lan's application to stay on Moran Star goes well, she will not return to Blue Star now.

But now that she is back, it means that the situation has changed and she may not be able to stay on Moran Star as expected.

Yun Lan paused with his fingers, and after a moment he let out a slightly choked sound.

After wiping the dirt off his body, Uncle Luo patted Yunlan's shoulder and comforted him: "It's okay. Our Canglan Star is also very good. We won't starve to death when we come back."

After all, she was the child she watched grow up. She must have suffered a lot in order to stay in Moran Star. How could they have the heart to blame her?

A drop of clear tears fell on the dry land at his feet. Yunlan sniffed and nodded: "Well, Uncle Luo, I will learn how to plant from you!"

Uncle Luo: "······"

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

After sacrificing countless more young sprouts, Uncle Luo finally couldn't bear it and drove Yunlan away.

"Your injury hasn't healed yet, so you shouldn't overwork yourself. 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. He returned to the room and stared at the Tuchola Mountain outside the window in a daze.

She doesn't seem to be very talented in planting. Wouldn't all the money she spent on buying B-level seeds be wasted?

Just when I was doubting myself, the optical computer showed that there was goods to be signed for.

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

Before I had time to take it apart and look at it, news about Yao Qiu came over.

[I bought the seeds and sent them to you. You can see how the quality is.]

Yun Lan opened the box and found three small bags of seeds inside. Each bag of seeds had a note on it, indicating what kind of seeds it was.

The number of seeds in the bag is not large, only about a dozen or so, but judging from the quality of the seeds, they are all plump and moist, and they are obviously B-grade species of the highest quality.

[The seeds are of very good quality. How much will it cost for me to transfer them to you?] These three bags of B-grade seeds will probably cost a lot of money.

[It didn’t cost much. I have a friend who has channels at home and sold it to me at cost price. There is no need to transfer money to me. When the crop matures, you can just send me some to taste. 】

Yunlan knew Yao Qiu's temperament. She said she didn't want money. If she had to give it, she would be angry.

It's just that the cost price is still a B-level product after all, and the cost price is not cheap either.

Unable to do so, Yun Lan could only say: [Okay, when the seeds come out, I will send you some to try. 】
