But then again, Su Chen has heard the special reason from Situ Jing's mouth more than once.

"The special reason you mentioned, is it the Demon Race?"

Vaguely, Su Chen also had some kind of guess.

When Situ Jing heard the words, she also nodded lightly, "At present, it is very likely to be the case, but more information is needed to make a judgment."

"..."

Su Chen heard the words and fell into silence.

For a long time, "It's really haunted!"

A faint sigh also quietly came out of Su Chen's mouth.

Ended the call with Situ Jing.

Su Chen thought for a while, and then contacted Boss Cao again.

"Water crystals and soil crystals?"

Hearing Su Chen's request, Boss Cao was also stunned for a moment.

Immediately with a big wave of his hand, he could not help but directly send a transaction application to Su Chen.

"This is a thousand water crystals and a thousand soil crystals, if you see enough, you can tell me if you are not enough."

In trading, the price is still just a power point!

It's like giving away!

And looking at the appearance of Boss Cao, it seems that he is not at all distressed.

"Good guy..."

Seeing what Boss Cao threw out with a flick of his hand, Su Chen was also silent.

This is a real dog owner!

There are so many things to throw away!

It's just terrifying!

However, although it was a slap in the face, Su Chen didn't want to take it for nothing.

Some things are not to be taken for free. Since ancient times, favors are the most difficult to repay. What Su Chen dislikes the most is to owe favors to others.

Therefore, Su Chen said directly:

"Brother Meng De, as the saying goes, gentlemen don't eat what they come to eat, Brother Meng De still follows the normal market price, and Brother Meng De and I can trade as normal."

Seeing this, Boss Cao was also a little helpless.

Su Chen's indifferent attitude gave him some headaches.

Why is it so difficult to make this kid owe favors?

Anyway, seeing that Su Chen still didn't intend to owe others favors, Boss Cao had no choice but to say:

"Little friend Su Chen, let me tell you the truth, in the intermediate farm space, whether it is a water-based crystal or a soil-based crystal, it is worthless."

"There were some things that I didn't tell you clearly before. Fortunately, it's not too late. I'll tell you clearly."

"You should have planted Xuan-order crops, right?"

Boss Cao suddenly asked back.

"yes"

Su Chen also nodded in response.

I was also a little confused about what Boss Cao wanted to say.

Seeing this, Boss Cao nodded and continued: "Since you have already planted it, you should find some problems in a short time."

"Starting from the Xuanjie, the growth of crops requires not only land, but also a more advanced water source!"

"If my guess is correct, you want water system crystallization, the purpose should be to obtain enough water resources to meet the needs of your farm, right?"

Without waiting for Su Chen's response, Boss Cao continued: "When my farm was upgraded, the area expanded rapidly. Like you, I wanted to find more water crystals to meet the rapidly expanding farm planting needs."

"But what I need to tell you is that ordinary water resources cannot guarantee the growth of profound-order crops at all, and what is needed for the normal growth of profound-order crops is water spirit beads!"

Water spirit beads?

Su Chen was taken aback.

In his mind, a guess also emerged immediately.

But before he could say more, Boss Cao continued:

"With your strength, when you were in the lower-level farm space, you should have obtained spiritual water, right?"

Hearing this, Su Chen nodded.

I also had a guess about what Boss Cao wanted to say next.

And what Boss Cao said next did confirm Su Chen's idea.

"What this water spirit bead produces is actually spirit water!"

"And the growth of the Xuanjie and the crops above the Xuanjie must be assisted by spiritual water!"

"Otherwise, if there is no replenishment of spiritual water for a long time, the growth of Xuan-order crops will be the same as the growth of ordinary ordinary-order crops without water resources, and they will fall into a period of weakness, or even a period of stagnation!"

"So, do you now understand why I said these water crystals are worthless?"

After listening to what Boss Cao said, Su Chen also completely understood.

"Then this soil crystal is the same reason?"

"That's right." Boss Cao nodded, "Like water crystals, soil crystals can only increase the farm's land, and it is only limited to farms below the Xuan rank!"

"The boosting effect on the Xuanjie farm is only 10%! Moreover, the strength of the farm floating island expanded through this soil-based crystal will be greatly weakened, as well as the strength of the surrounding space!"

"In the history of the intermediate farm space, there are many potential newcomers who are bewitched by some malicious farm owners to use soil crystals to greatly increase the area of ​​their farm floating islands"

"In the end, the farm was broken, and the demons came!"

"I don't think I need to say more about the ending. These things are not secrets. As long as you have the heart, you can understand them."

"Therefore, in the intermediate farm space, few people are willing to use soil crystals to expand their farms"

"And for the Tianjie farm, the soil crystal has no effect at all!"

"If you want to greatly expand your farm, you can only do it through more advanced earth spirit beads."

Boss Cao, who made up his mind to win over Su Chen, also told Su Chen everything he knew.

When Su Chen heard this, he was completely stunned.

It turns out that there are so many secrets in it.

Water crystals are fine.

After a long time, when the growth of Xuanjie crops is restricted, he can naturally find the problem.

But the problem with the crystallization of the soil system...

At this moment, Su Chen was even a little fortunate. Fortunately, he did not directly expand the floating island of the farm with soil crystals.

As for whether Boss Cao would lie to him.

Su Chen thought this was unlikely.

After all, these things are all he can inquire about.

Even if Boss Cao wanted to deceive him, he was unlikely to use such low-level means.

Of course, as for the specifics, Su Chen will go to verify it by himself later...

However, after learning about this, Su Chen still proposed a transaction with Boss Cao.

According to what Boss Cao said, the water-based crystals and the soil-based crystals really don't have much effect.

But that's for someone else.

It's useless now, but what about after synthesis? ?

Chapter 343 Black Market Invitation Letter, Two Million Spirit Crystals

After all, he is not "someone else"!

"Well, if you want, I'll give you all of this in my hands."

Seeing that Su Chen still wanted to trade earth crystals and water crystals, Boss Cao subconsciously thought that Su Chen didn't trust him.

Ready to take these things back to experiment.

In this case, Boss Cao had no choice but to take out all the inventory in his hand.

"I don't have too many of these things in my hands. In terms of price, they are not worth much. You can just take a spirit crystal."

When setting the price, Boss Cao said casually.

There are more than 1,000 water-based crystals and more than 3,000 soil-based crystals in total.

This is his entire inventory.

After all, he didn't have much interest in collecting these low-level things.

In addition to the ones given to Su Chen before, it is already all in his hands.

"..."

When Su Chen heard the words, he was also silent.

Seeing that Boss Cao really didn't care, Su Chen also took a spirit crystal according to Boss Cao's request and made a deal with Boss Cao.

After the transaction was over, Boss Cao suddenly spoke again:

"Little friend, if you are really interested in these things, I suggest you go to the farm space trading market, where there are many strange things to trade"

"As long as you have spirit crystals, even the battle slaves of the heaven rank can buy them. The sun stone and moon shadow stone you need may be available in the trading market. Of course, there are also those cat maids that I gave you before."

Speaking of the end, Boss Cao suddenly has some meaning.

There are some jokes in the words.

Seeing Boss Cao's meaningful appearance, Su Chen frowned slightly,

"Catwoman slave?"

"interesting……"

Su Chen had just come up with the idea of ​​using Catwoman slaves to build an assassin army.

Now Boss Cao has directly provided him with a channel.

Can only say that it is really worthy of Cao Cao?

Said that Cao Cao Cao Cao arrived?

But where is this market?

how to get to?

What are the conditions?

What to watch out for?

Su Chen had more doubts in his heart.

With these doubts, Su Chen also raised his own question with Boss Cao again.

"How did the trading market come about, I don't know"

"This market was formed before I came to the mid-level farm space"

"It's actually a floating island, but it's special."

"As long as you get an invitation from a senior farmer and spend a certain amount of spirit crystals, any farmer can go to that place."

"In terms of trading, there are two markets, the bright market and the black market."

"Ming City is formed by the special rules of farm space. In it, if you pay a certain amount of spiritual crystals, you can temporarily rent a booth to trade with other people."
