After wasting some effort to explain to the strawberry essence that they didn't really need to work so hard, the strawberry essence was a little disappointed, but it still slowed down the speed of growing fruit and did not deliberately ripen its own fruit.

Su Luo put the second batch of big strawberries together with the thirteen of the first batch, exactly twenty, each of which was the size of a fist, and the weight started at least half a catty, and twenty was ten catties, which was comparable to the number that needed to be handed in in half a month.

However, Su Luo didn't have time to think about it so much now, and after she sorted out all the seeds, the first thing was to take out the common sense of the light brain and start to make up for this world.

For example, in terms of prices, planting-related, and all the words that she didn't understand mentioned by the Zheng steward in the purchase shop today, Su Luo searched for it.

The first is the purity grade.

The interstellar purity level is divided into seven, of which the radiation level above 60 is unqualified and inedible for humans.

This substandard food is eaten into the human body, and the radiation contained in it can destroy the human body.

The radiation dose of 60 and below is collectively referred to as qualified.

Among the qualified foods, they are divided into one level and two levels, all the way to the fifth level, of which the first level is the best and the fifth level is the second.

Level 5 is food with a radiation dose of 41-60, Level 4 is a radiation dose of 31-40, and so on, a level 1 has a radiation dose of 1-10.

The radiation dose of strawberries brought by Su Luo is 0, and the radiation dose of 0 is supergrade.

Premium food is scarce, but it is not absent, which is why although Su Luo has attracted attention today, it is not too eye-catching.

In addition to this, there is the energy index.

Speaking of energy index, Star Marines must be mentioned here.

Space marines are similar to planters, except that one is a human born with a talent for fighting, and the other is a human born with a talent for planting.

Unlike Planters, there are more Space Marines.

Most of the Space Marines are relatively strong, but their physical consumption is also very serious, especially when fighting the Zerg in the mecha, they need to replenish the consumption of materials containing energy.

And the energy here refers to the energy index detected in the strawberry.

Normally, most of the fruits on the market have an energy index of less than twenty, although this fruit has energy, but because it is too little, it cannot be used as a military supplement for soldiers, so it will be used as a commodity commonly sold in the market.

As long as the energy index exceeds twenty, it will be bought by some special departments to provide it to special people.

Once the energy index reaches 60 or more, it is a proper munitional item.

Theoretically, there is no upper limit to the energy index, but so far, the food with the highest energy index is only 150.

Su Luo's batch of strawberries can still have ninety energy under the conditions of meeting the super-grade, which is already considered superb.

If the energy index can break 100, then Su Luo's income today can be several times higher.

Because the difference between the energy index of 99 and 100 is not just a simple '1'.

Where the energy index is high, the radiation amount must be high.

At present, the army is supplied with a batch of energy indexes that have just broken 100 all year round, and the purity level is level 2 - this is already the limit of the whole interstellar.

From the perspective of the human body, the best food they can get so far is a premium food with an energy index of 95, and Suluo's strawberries are already infinitely close to this value.

This is also the reason why Steward Zheng is willing to buy these strawberries at five times the market price.

……

After reading this information, Su Luo only felt a chill behind him-

OK...... Fortunately, the energy index of this batch of strawberries did not exceed 100, otherwise even if this store is not a strong buyer and seller, it is difficult to guarantee that she will not be exposed.

At that time, what she will have to face is not as simple as buying and selling.

As the information of this world fills in, the more Su Luo understands, the more cautious the whole person becomes.

After calming down a bit, she searched for a lot of information about the planter.

When searching for news about Lingzhi, the almighty search engine seemed to have encountered some big problem, and the only relatively official news was a year ago.

No wonder Zhang Hua doesn't understand...... It's impossible to understand.

Because the information about the spirit plant is only a few words, the only accurate information that Su Luo can understand is that the spirit plant is a special creature that may be accidentally produced in the process of the planter giving birth to plants.

After cultivating the spirit plant, the identity of the planter can be transformed into a spirit planter, and his status and treatment are far superior to that of the planter.

As for what the spirit plant does, what it looks like, and how it came about, she didn't find any relevant information, and she didn't find any relevant information after searching for a long time.

In desperation, Su Luo could only continue to search for information about the planter.

At present, there are tens of billions of people in the interstellar world, and there are less than one million planters who can be registered, and the spirit planter is one in ten thousand among the planters.

From this point of view, even if the strawberry essence is a spirit plant, Su Luo can't be too relaxed.

After all, the scarcity of spirit plants is enough to prove their preciousness, and it is difficult to guarantee that no one will see the intention of getting rich.

Based on what she knew so far, the strawberry spirits said they could give birth to their kinds, and not only that, but they could also protect them from the effects of radiation in the soil.

Assuming that strawberry essence is a spiritual plant, having a spiritual plant is equivalent to prostituting a planter who helps to grow plants, and not only that, this planter can also ensure that the final result has a low radiation content......

Of course, the biggest disadvantage of spirit plants is that they can only give birth to the same clan, just like strawberry essence can only give birth to strawberries, and cannot affect other fruits such as apples, bananas, grapes, etc.

But that's enough, with the existence of such a spirit plant, at the price of food in this world, this is simply a walking 'money printing machine'.

The more he thought about this, the more Su Luo wanted to strengthen his strength.

She poured out the seeds of a thorn vine—there were not many seeds in this pack, only twenty or thirty, whether it was to save some use, or she was worried that she would not be able to control the thorn vine, she was only going to give birth to one for the time being.

Before giving birth, she habitually examined the radiation factor inside the seeds - like other seeds, the seeds of the thorn vine have many black-gray spots.

Su Luo skillfully removed the radiation factors inside one by one, and then carefully injected the wood energy into the seed.

Like strawberry seeds, thorn vine seeds begin to sprout rapidly.

Unlike the strawberry vines, which are green and full of life, the rattans of the thorn vines are dark green, and the dark color adds a bit of inexplicable danger.

Now that the rattan is only half a meter long, Su Luo can already clearly see the sharp spikes on the rattan...... If you look closely, you can even see that there are shallow barbs on this spike.
