Sitting on the chair, with the soft light of the bedside lamp next to him, Cheng Lin stroked the stack of papers in his hand, very embarrassed.

If when he first started practicing, he would still have a headache because he didn't have any abilities to learn, then who would have thought that after just over two months, he would already be able to pick and choose with a stack of abilities.

It's a great feeling.

The trade between Tris and the Elves was a partial exchange of power research, with the Elves providing some ways to cast their magic, and Tris providing a field map of the abilities.

Of course, not all of them are offered, if not very little, but one or two of each category are given.

After all, all we need is an opportunity to cut into the other party's power system.

Although Cheng Lin really wanted to get more field maps, he couldn't do it too explicit after all.

Plus he doesn't need much.

Although it is theoretically possible to learn all of them with a full-term affinity physique, human energy is limited.

Blindly coveting "more" is likely to lead to not being "refined" enough.

After removing the ability of level 3 and below, he has the ability of level 4 and 5 that he currently has.

As for the six grades and above, I don't know if they are human beings and have not studied them.

It's still hidden and tucked away and not provided.

Take out the fifth-tier ability first, and the rest is just the fourth-tier ability.

There are eight copies in total.

These days, Cheng Lin has studied these abilities seriously several times, but he has never cultivated them.

Mainly considering that the time for me to enter the fourth product is too short.

I want to settle the realm first.

"My current cultivation is four grades and one stage, and according to the division of Terri's cultivation, the current spiritual energy reserve in my body should be 50 quasi...... This is already a lot, if it is a third-grade ability, it can easily release a dozen of them, without any pressure, let alone a lower grade...... The more powerful the ability, the more aura it consumes, and correspondingly, the more powerful it is......"

"My most powerful means at the moment is still He Jian...... After smelting, the strength of the He Sword has increased by leaps and bounds, and it only needs to pour the spiritual energy into it to release the sword qi comparable to the five-grade combat technique...... However, attrition is also terrifying, and with reference to the combat experience with the Black leader, I can only launch it three times at most, and I will be drained......"

"The cost of four-rank abilities shouldn't be so scary, but it's a lot to think about, so this further limits the types of abilities I can learn."

Sitting on the chair, pinching the paper, Cheng Lin thought about it.

These days, he also has a clearer understanding of the Four Qualities Realm.

The biggest difference between it and the three qualities is probably what is required for cultivation...... The first stage is 50 standards, and the second stage is 100 standards, and when the four products are at the peak, they need to approach the 500 standard reserves.

In other words.

Under the premise of a balanced absorption efficiency, there are only two ways for him to move up the rank.

Either it takes time to fill it, for example, it used to take a week to move up a rank, but now it takes a month.

The second way is to use resource heaps.

It's like he upgraded from the first stage of the third grade to the third stage, and he used a large number of "white roses" to pile it up.

Converted into cash, no matter how you look at it, it's tens of millions.

If you still want to copy this route and try to pile it up with resources, I'm afraid that hundreds of millions of dollars will not be enough for Cheng Lin to consume.

And he obviously doesn't have hundreds of millions of ......

"Now that the white roses have been consumed by me, the spiritual plants brought back from the floating land have been planted again, and they cannot be eaten for a while......

The only remaining resource is spirit ore.

Well, I've embezzled hundreds of ores from the two clans' deals, but a considerable part of them is still to be reserved for the refining furnace.

He Jian is my biggest hole card, and referring to this time, if you want to smelt He Jian, you must consume a lot of ore to supply the consumption of the refining furnace......

I have to keep a large part of it as a reserve to ensure that once I find the third He Sword, I will have enough power to make it smelt successfully. ”

"In this way, there is very little left for my own cultivation...... I'm so poor. ”

After a simple calculation, Cheng Lin suddenly felt so pitiful.

I thought that I had made a lot of money this time, but after removing all kinds of consumption, I found that there was only a little bit left......

"What the hell is going to do with this?! At this point, when will I be able to upgrade to the top of the fourth grade? A few months? Half? A year? Cheng Lin suddenly despaired.

At this moment, he suddenly deeply understood the true meaning of Huang Yin's "four products are different from three products".

The ability of this loser is not the same at all.

Looking at it this way, how much will it consume after upgrading the fifth and sixth grades?

Cheng Lin had heard a saying before, saying that if the Xia family wanted to cultivate a college student, they needed at least one million.

Now it seems that if the country wants to cultivate a four-grade one, it will take tens of millions, but what about the five-grade? Hundreds of millions?

Six products? Seven products?

With dozens of departments and bureaus across the country and hundreds of thousands of cultivators, how much financial pressure does the country need to bear?

Cheng Lin shuddered just thinking about it.

Of course, compared to the size of the country, there may not be much pressure at present, but what can be done?

With the passage of time, there will definitely be more and more high-grade cultivators in the future, and the consumption will also increase.

"It's no wonder that the country opened up trading so quickly and set up a mission hall, which is trying to make money."

Sighing, Cheng Lin couldn't help but feel a little worried.

"By the way, when I go back and make public the news that I have been promoted to the fourth grade, there is still a material subsidy in the academy...... I don't know how many, I hope it's not too stingy. ”

Shaking his head, Cheng Lin put this headache behind him and began to face the ability choice instead.

In fact, in the past two days, he has already made a selection.

The four-rank ability is more complex than it used to be, so it's harder to master.

Cheng Lin is currently only ready to learn two.

The first is still the "perception system" ability obtained from the future Zhu Sha.

Speaking of which, this set of abilities is his most commonly used, one is to launch concealment, which can be used often, unlike other hole cards, which can only be hidden and tucked.

Second, it is very practical.

For example, the "Hazy Eye" ability is a product that he still uses a lot.

In addition, the construction of four-grade abilities is complex, and it is very difficult to learn a completely unfamiliar one, and this set of abilities is very related to each other because it comes from one person, and the difficulty of learning is greatly reduced, which is a well-deserved choice.

……

Draw out the selected four-fret.

Cheng Lin put the rest aside and looked at it by the light.

It's a weird name: synaesthesia

As for the specific effect, it is still unclear, and remembering its structure with his brain, Cheng Lin closed his eyes and began to try to build a "synaesthesia" field.

It took about ten minutes for him to finally build it.

"Boom!"

At the moment when the "synaesthesia" was formed, a roar appeared in Cheng Lin's mind, and then, an extremely familiar scene appeared:

The spiritual power condensed into an invisible tentacle, spreading out of the body, and the scene seen by the tentacles appeared in his mind.

"This is the tentacles?"

Cheng Lin was stunned.

This ability ...... It is clearly the "tentacles" of the three-grade ability.

But...... How can it be?

Although "synaesthesia" is indeed an ability evolved from "antennae", it is not exactly the same, right?

"Could it be that the distance has increased?"

Cheng Lin guessed.

Tentatively controlled the spiritual tentacles to circl in the spirit realm, circling along the border, experimenting with extending distances.

Because of the promotion to the fourth grade, he found that the extension length had indeed increased, but that was all, and there was nothing special about it.

This couldn't help but make him frown.

"It shouldn't be, how can you say that it doesn't make sense that there is only such a small increase, right? The effect has not been improved, but the consumption has increased several times? If there is no reason for this, could it be that this field map is wrong? ”

Cheng Lin was confused, he had no clue, he was thinking hard here, and the spiritual tentacles continued to extend, but the spiritual realm was limited after all, and after a few turns, the spiritual tentacles extended to the sky above the medicine field.

In the medicine field.

The black magpie is pitifully catching insects in the ground by the "moonlight", the sky is pitiful, since it was born in the zoo pampered, where will it catch insects?

Fortunately, the area of the medicine field is not large, and Lingzhi also has a certain ability to protect himself, so he wasted a lot of effort and finally cleaned the medicine field.

After finishing the work, it immediately flapped its wings and flew back, wanting to go to Cheng Lin to invite credit.

However, as soon as it jumped up, it just hit the "spiritual tentacles".

The next moment, I saw that the bird's feathers all over its body were "fried", and its small blue eyes were round.

"Chirp?!"

At the same time, Cheng Lin, who was frowning and thinking hard, suddenly accepted an emotion.

Yes.

Sentiment.

The mood was vague and chaotic, but it could be described as "surprised" or "confused".

If you have to translate it into human language, it's probably equivalent to a sentence: "Damn, what is this?" ”

Cheng Lin was stunned and opened his eyes.

At this moment, he clearly felt that he had a secret connection with the black magpie.

Synaesthesia?

Could it be that this is both the so-called synaesthesia?

The spiritual tentacles I extend not only have the function of "eyes", but also serve as a channel for transmitting information?

Cheng Lin's eyes lit up, pursed his lips, and tentatively passed a thought in his heart: "Can you hear me?" ”

The next moment, he saw the black magpie flying over the medicine field suddenly looking at him.

At the same time, he also received a wave of "panic".

"Listen to my orders and land."

Passing on this thought, Cheng Lin saw that the black magpie first glanced at him, and then landed on the ground obediently.

"Take off, fly in the direction of the tree!"

"Come back, sprint in the opposite direction!"

"360-degree rotation in the air!"

"Dive!"

"Pull up!"

Cheng Lin began to give instructions through his spiritual tentacles non-stop.

The black magpie, who had no idea what was happening, could only be forced to do what he commanded.

After some tossing, Cheng Lin finally laughed.

He smiled happily and was excited.

At this moment, he finally understood the meaning of "synaesthesia"!
