In the current situation of the planet, there must be a large amount of income.

What industries make money?

Pure fruit and vegetable farming, of course!

It's just that the 0 radiation environment is more difficult to do, so it is necessary to wear a protective cover.

Protective covers, according to size, are divided into personal protective covers, small civilian protective covers, and large public protective covers.

For personal use, it is only a few square sizes, and Liu Jingxing's one belonged to the personal protective shield.

The largest of small civil use is the enveloping area of 100 acres of land.

Large-scale utilities can cover hundreds, or even thousands of square kilometers.

(1 acre of land is 666.66 square meters, 1 square kilometer = 1500 acres of land.) ）

According to the function, there is a single radiation isolation shield, which has a variety of functions: anti-radiation, temperature regulation, anti-missile, anti-sand, anti-thunderstorm, anti-tsunami, anti-typhoon, anti-earthquake and so on.

Versatile, dead expensive!

And if it is a radiation isolation shield, the personal is about tens of millions, and the size of 1 mu of land is about 2 billion, the larger the enveloping range, the unit price will be slightly cheaper.

Large, that's really just a look.

The unit price of 1 square kilometer is around 100 billion, while the smallest is 10 square kilometers, and the price is about 1.05 trillion yuan.

And this kind of 10 square kilometers, when used, energy consumption plus maintenance, etc., is about 10 billion per year.

She can't afford it, so Tang Xuan has the financial resources to buy it!

After reading the relevant prices, Tang Ranran entered the farm again, looked at the computer in the study, and pulled out the ordinary crops that he had unlocked that could be planted.

Level 0: Grass, radish, carrot

Grade 1: Chinese cabbage, garlic

Grade 2: Rice, wheat

Grade 3: Corn

Level 4: lettuce, potatoes, rape, bok choy

……

The purification value does not need to be high, low points are fine, the key is to have a shorter growth cycle, search your own memory, recall the growth cycle of these crops......

Rapeseed!

Small rape can generally be picked for stir-fry in about 50 days.

However, due to the backwardness of cooking skills here, small rape, a vegetable that needs to be cooked, is not very popular with the public.

The public prefers melons and fruits.

However, the growth cycle of melons and fruits is quite long.

After thinking about it, Tang Ranran finally chose the first one: pasture!

She remembers that in general, the seeds are sown, and they will grow tall in a month.

People may not like to eat grass, but study a recipe to make a pure nutrient solution from pasture, how can a 0.8 forage make a 0.4 nutrient solution?

0.05 Xinliangqinggan can sell for 988 Star Coins, even if it is a bad 0.4, at least 2000 Star Coins, right?

If artificial cultivation is realized, then such a pure nutrient solution alone can pull up the economy of the entire planet!

For example, something like pasture, a protective cover, to create a 0 radiation environment, as long as weeding, watering, not thirsty, not sunburning, should not die, right?

So decided!

After refining so many furnaces of Qingling Pill, before the vegetables were about to be harvested, Tang Ranran stopped working.

After looking at the brain for a while, I collected the dishes.

After harvesting the vegetables, the No. 1 field will do the planting task, the No. 2 spiritual field, the No. 3 field will be left, and the other fields will continue to grow vegetables.

Field No. 3, planted with pasture.

There was no need to sprinkle chemical fertilizer, and as soon as the grass seeds went, Tang Ranran flew out of the house and came to the No. 3 field.

The moment I stepped on the No. 3 field, the land entered a state of real growth.

Tang Ranran used the ability to catalyze, and the grass was only 0.8, which was very simple to plant.

In less than half a minute, the land below was already verdant.

Tang Ranran studied it, and the grass on the farm should be alfalfa.

After urging planting and collecting a large number of small seeds, Tang Ranran left, and with an operation on the computer, the field was restored and vegetables were continued.

After finding a flower pot and sowing seeds, Tang Ranran urged a pot of green alfalfa.

After plucking a leaf, Tang Ranran measured the purification value.

Sure enough, the leaf purification value was 0.8.

Taking the lead, Tang Ranran took a bite and chewed it, in general, it was the taste of grass, but with a little fragrance.

It's not delicious, but it's not unpalatable.

Use your brain on the formula to make a fragrant pure nutrient solution, which will definitely not be lower than the market price.

Tang Ranran took a pot of grass he planted out of the space, and a CALL called Kang Chen and asked him to come over.

The distance was a bit far, and about an hour and a half later, Kang Chen arrived.

After half a month, when they met again, Tang Ranran was shocked.

Kang Chen, a handsome guy who was originally masculine and tough, is a handful of scum at this time, his eyes are blue and black, and his face is yellow, and he looks like a night owl with kidney deficiency who has stayed up for a few nights.

It seems that this time has been very busy.

Kang Chen entered the room, Tang Ranran didn't talk nonsense, and went straight to the point.

100 billion yuan of star diamond raw ore was donated to the Charity Bureau in the name of her Tang Ranran and her parents.

Then there is the flower pot overgrown with pasture, as for the source of the grass, Tang Ranran was vague, a sentence of 'windfall', fabricating a legal source, that is, Kang Chen wants to use his brain.

At present, as a planet under private jurisdiction, although the Pure Food Certification Center of Suping Ruixing has not been cancelled, it is no longer considered an administrative department subordinate to the empire, and it no longer has relevant administrative powers.

So, go to the planet next door for certification.

As the shopkeeper, after Tang Ranran gave something, he naturally didn't care about the follow-up, the forage patent registration or something, of course, Kang Chen went to do it.

Tang Ranran briefly said his thoughts, buy a small civilian radiation isolation shield, 100 billion, can buy about 55 acres. The annual maintenance fee for the protective cover is almost 10 million.

Find a place with good soil and suitable climate for planting, install a protective cover, and plant pasture.

The income from pasture is the main source of income for the planet in the future, as well as the source of loan repayment.

The plan is good, but Kang Chen is worried that this pure plant is not easy to grow.

Tang Ranran mentioned intentionally or unintentionally, "After successful registration, give full play to your connections, think of a way, find a wood department, and help?" ”

Although the person who came into contact with Tang Xuan's trumpet was Wu Lihua, he also added Kang Chen's friend.

Tang Ranran mentioned this, and Kang Chen immediately reacted.

That wood-based Tang Xuan who helped them grow food!

"I know a wood, I'll try!"

"Uh-huh."

……

After a few words, Kang Chen put away the star diamond scraps, and as for the flower pot planted with pasture, it was carefully held in his arms and shrouded in the spiritual power barrier.

Leaving Tang Ranran's hotel, as soon as he went back, Kang Chen regarded the matter of pasture as a top priority and began to deal with it as soon as possible.

Sent to a plantation lab with zero radiation.

The first is to take a photo, fill out the information, and send it to the pure food certification center on the planet next door.

As a mixed system, Kang Chen can be regarded as a bit of a connection, and he delivered the information, but he was afraid of being delayed, so Kang Chen entrusted a relationship.

After doing this, Kang Chen immediately opened the Zhi Brain address book, found Tang Xuan, and tentatively sent a message.

[Kang Chen: Hello Your Excellency Tang Xuan, I take the liberty to disturb you. 】

Automatic second back.

[Tang Xuan: I'm resting, I'll contact you later.] 】

Although both the deity and the trumpet are Tang Ranran, as a wooden system, she has to hold on, not to mention, Tang Xuan's side is dark at night, she is sleeping.

Can't be too deliberate.

Even if he is a junior brother with a contract, Tang Ranran is very cautious and reluctant to expose his trumpet.

However, according to her plan, she would inevitably contact Kang Chen with Tang Xuan's trumpet, if Kang Chen found any flaws and guessed the truth, there would be no way.
