Yu Cang began to carefully examine Wang Chu's deck.

Well...... Was this spell used?

Although Wang Chu's deck is mixed with many systems, in which Yu Cang even saw the Sword of Judgment of the Dragon of Light and Shadow deck, the core is still a soul card called "Soul Abyss Burial".

Soul Card Name: Soul Abyss Burial

Category: Spell Cards

Quality: Epic

Attributes: None

Ability:

[Announcement]: When activated for the first time, the quality of this soul card is considered rare, and the ability becomes: Attach the "Abyss Mark" to all other spell cards in the deck.

[Gift]: When the Abyss Burial of Souls is on Death Cooldown, all Soul Cards carrying the "Abyss Mark" will leave an Abyss Crystal behind after being used.

[Burial]: This ability must be triggered when Soul Abyss Burial ends its death cooldown as a rare card. Consumes all Abyss Crystals, retracts all Abyss Marks, and activates the Soul Card regardless of consumption, creating an "Abyss" in the sky, which will devour all Soul Energy Products and continuously increase the mental stress of the manipulated target.

……

Although this soul card is epic, it can be used as a rarity.

The general usage process is to start the game with [Announce], and then continue to use the spell card [Gift] during the battle, and finally when the death cooldown ends, it will be directly [Burial].

The death cooldown of this soul card is very long, as long as ten minutes, and during this time, some soul cards can be reconnected even if they are disconnected.

In this case, there is no doubt that a considerable number of Abyssal Crystals can be accumulated, and the power and duration of [Grand Burial] are bound to the number of Abyss Crystals, so ...... If done correctly, when the ten minutes are up, it will be the opponent's death.

With enough abyssal crystals, the power of the soul energy burial is completely at the level of the corpse of the ancient demon...... At the very least, when it comes to dealing with soul card masters, the power is at a level.

[Grand Burial] can devour the product of soul energy, and in this process, all summoned beasts cannot escape. Even if it is devoured, it will continue to increase mental stress, so that you can't operate.

This is a very pure soul card for the soul card division for the civil war.

However, the ten-minute death cooldown is a very fatal shortcoming - taking the duel that Yu Cang has experienced as an example, there are only a handful of battles that exceed ten minutes, and there may only be the one where the fourth-level leapfrog fought the fifth-level Xing Su at the beginning.

It's the same with other soul card masters - there won't be ten minutes of a normal duel at all, and for those soul card masters who are very strong, it's not uncommon to end the battle quickly in advance.

Therefore, Yu Cang also saw some soul cards in Xing Su's deck that could shorten the death cooldown of spell cards...... Seriously, not very useful. Under normal circumstances, using all of them will shorten the death cooldown to about seven minutes, which is still a long time.

Not to mention that the complex battlefield environment simply won't allow you to use so many non-combat cards.

Therefore, the spell card system with the Abyss of Souls Burial as the core is not practical, at least not in heads-up.

However, Wang Chu will eventually participate in a four-person battle, with three people covering with all their might, and there are strong field control players like Lan Jun among his teammates, so the probability of holding out for seven minutes is still very high.

But now, since Yu Cang has promised to help transform the deck, he will naturally not let this shortcoming continue.

With a wave of his big hand, Yu Cang took it to write a pen, and after writing and painting for a while, he drew an identical "Soul Abyss Burial".

In his eyes now, this level of epic soul card can be easily drawn.

Directly open the entry bank, and look into it.

"Well, the Soul Abyss Burial is very suitable for the play of the entry [Sustainability], so ......"

The implantation success rate of this entry is 32%!

Without hesitation, Yu Cang directly selected [Sustainability] and confidently clicked on implantation.

【Implantation failure】

Yu Cang: ......

Okay, good, play like this.

It doesn't matter, the implantation cooldown of the rare entry is only ten minutes, and he just needs to try a few more times.

However, what he didn't expect was this.

It wasn't until the seventh implant that Yu Cang finally succeeded.

“…… How so. ”

After success, the highlight in Yu Cang's eyes quickly lost, and the whole person collapsed on the chair, questioning life.

Seven, seven times.

That's a 1 in 3 success rate!

With such a high success rate, it took him an hour to successfully implant it?

Is this reasonable?

After being sad on the chair for a long time, Yu Cang's eyes were certain, and he gritted his teeth and looked at the soul card in his hand.

You'd better be useful!

……

Soul Card Name: The Abyss of Souls Beckons

Category: Perpetual Spell Cards

Quality: Epic

Attributes: None

Ability:

[First Rite]: When activated, the quality of this soul card is considered rare. Once activated, attach the "Abyss Mark" to all other spell cards in the deck.

[Gift]: When the Abyss Soul Summoning Array exists, all soul cards carrying the "Abyss Mark" will leave an Abyss Crystal after being used. And according to the number of abyss crystals, improve the quality of the soul card, the highest epic.

[Final Rite]: When the quality of the soul card reaches the upper limit, a certain number of abyssal crystals can be sacrificed at any time to summon the corresponding abyss to descend and devour the soul energy product.

……

Yu Cang's eyes couldn't help but light up.

It's what he wants!

Perpetual Spell Cards!

Sure enough, the [Sustainability] entry is the key to creating a Sustainability Spell Card.

After implanting [Perpetual], this spell card, not to mention the power, is definitely more practical than the original.

If the original version is to be used a second time, it will take at least seven minutes, in fact, during this time, if you keep using the soul card, the abyss crystals it has accumulated will be enough to make up an "epic" attack.

But when I had enough, I couldn't use it, so I had to wait stupidly for seven minutes, and if the battle was a little more anxious, maybe I would have to walk through the ten minutes in its entirety.

Now, this soul card will always exist on the field after it is activated, and as long as you accumulate enough abyss crystals that can perform "epic" attacks, you can use the extra parts as you like...... It is equivalent to that every spell card after that has an additional "Abyssal Devouring" effect.

What's more, this card is quite flexible to use, you can use it to fight continuously, but you can also accumulate crystals all the time without using them, and finally release them all in one blow like before...... Even after a one-hit victory, you can continue to fight.

The card's increased flexibility and practicality is obvious.

"Not bad." Yu Cang was very satisfied.

So next......

Yu Cang glanced at the cooling [Perpetual] in the entry library, and did not choose to continue implanting, but directly took out the development potion, evenly applied it to this soul card, and began to study the difference in the lines.

For soul card masters, the knowledge they have mastered can become their own.

He had already mastered the details of the pattern of the "Soul Abyss Burial", and now, in the face of this brand new soul card in his hand, he only needed to make a slight comparison in his mind to find out what made this soul card a perpetual spell card.

It sounds quite simple, but when Yu Cang really started researching, he found that this was not the case at all.

The texture of the soul card in front of me is indeed somewhat familiar, but its rhythmic details are countless times more complicated out of thin air, as if every line of the original pattern has been replaced with a finer and more complex pattern pattern, so that although it is still this group when it is far away, it will ...... once it gets close It will go straight to a phobic attack.

"Hiss......" Yu Cang gasped directly.

Is this perpetual magic card so difficult for Rhythm?

He didn't even notice this when he made the dictatorial sword.

After all, the Dictatorial Ritual Sword is a connection summoning card, and its body is in the starry sky vision, and the rhythm on the soul card is just an empty shell that plays a guiding role, and there is no research significance.

Now, when Yu Cang saw the rhythm of the perpetual spell card for the first time, he was immediately deeply shocked.

This level of complexity doesn't even look like an epic soul card anymore.

The highlight in Yu Cang's eyes quickly lost again, and he collapsed in the chair with a muffled snort.

It's bad, it seems to have found a problem for myself.

Isn't that a source of guilt for yourself!

Youyou sighed, and Yu Cang sat up.

It's useless to complain...... Anyway, the way the perpetual spell card is drawn is going to be cracked sooner or later, so let's hurry.

……

This study lasted from morning to evening.

When Kaede came to say goodnight to him, he realized that it was late.

Opening the personal terminal, Gu Jieshuang sent a lot of messages - today she has an exam that needs to be taken in the field, so she is not on campus now.

By the time of tomorrow, her exam would be complete.

A smile appeared on Yu Cang's face.

……

The next day

Yu Cang rushed to the laboratory very early, but it was not until the afternoon that he finally barely figured out the rhythmic pattern of the perpetual spell card.

I have to say that the rhythm of this spell card is really complicated...... The soul card directly produced by the entry recorder is already the most concise and unencrypted version, and Yu Cang still has the drawing method of the predecessor of this soul card, even so, it still took a day and a half to figure it out.

However, after figuring it out, Yu Cang was almost confident about how to draw a perpetual spell card. Now, he can start experimenting with drawing some perpetual spell cards on his own, without relying on the entry recorder.

But then there is more time to spend on it...... Yu Cang spent a day researching, and he wanted to design all the rhythms of a spell card into the corresponding perpetual patterns...... I don't know how much time there is.

If the thinking is a little bit smoother, it may take a lifetime.

Thinking of the terrifying workload that this might bring, Yu Cang's eyes flickered.

Well, it's better to rely on the entry recorder appropriately, and there is no shame in it.

He stretched, got up directly, and called Lin Yunqing to the test site.

It's not a rush to make more perpetual spell cards, let's test what are the characteristics of this spell card.

In fact, when he used the Dictatorial Sword, he had already felt that this kind of spell card was different from ordinary spell cards in use...... One obvious point is that the dictatorial sword does not take up mental pressure.

This is actually a very perverted thing, if the perpetual spell card does not take up mental stress, then it can be used infinitely...... There are certainly limitations, but they are not obvious on the dictatorial sword, so it needs to be verified by certain experiments.

"Senior, are you okay now?" Lin Yunqing looked at Yu Cang expressionlessly.

After returning to the card making house yesterday, there was such a soul card hanging in front of him, and he couldn't sleep left and right.

Just get straight to the point and keep researching.

Because of this, I didn't sleep long yesterday, and my face at the moment was naturally not very good, with two conspicuous dark circles hanging under my eyes, which was eye-catching.

"Of course I'm fine." Yu Cang yawned, "Hurry up and prepare, it's time to record the data." ”

“…… I'll tell the defrost. Lin Yunqing turned on the computer as he said.

Yu Cang's breath stagnated, and the yawn in his mouth suddenly swallowed in his throat, and he couldn't beat it.

"Ahem, that ......"

"Senior, to borrow a sentence from you: scientific research also has requirements for physical health." Lin Yunqing had already prepared everything, and his eyes became serious, "Let's start, shall we?" ”

"Uh...... Did I say that? Yu Cang said with a little humility, but seeing her attitude of not giving herself a chance to speak, she had to expose the topic, "Then let's start!" ”

The Soul Abyss Summoning Array is only equivalent to a rare card when it is activated, so there is no soul energy pressure at all, and Yu Cang has only consumed ordinary soul energy, and it has been successfully launched.

Suddenly, a huge soul card phantom opened behind the firmament, and the mysterious formation in it became brighter and brighter, and when the soul card phantom had gradually faded, the formation was still in the air!

The bright purple circle emitted bursts of evil light, and from time to time a thick black mist surged in it, making it look very evil.

"Huh?" Lin Yunqing's eyes lit up, "This is ...... Perpetual Spell Cards? Senior, have you finally found a way to draw perpetual spell cards? ”

Yu Cang's dictatorial sword, she naturally knows.

Spell cards are known to deal a lot of damage or buffs for a short period of time, if they are always on the field...... The intensity is definitely full.

No matter how you think about it, the superiority of this spell card is far superior to normal spell cards, if all spell cards can survive forever...... There is no doubt that the deck composition of all soul card masters is going to undergo another change.

Lin Yunqing has lost count, how many times she put the word "change" on Yu Cang's achievements, in short, now, she is no longer surprised.

When he saw the dictatorial sword, Lin Yunqing asked Yu Cang, but the answer he got was that he couldn't make a second perpetual spell, and he didn't have any ideas for the time being.

In this regard, Lin Yunqing, who has become a senior Yu Cangchui, naturally does not take it to heart, with the brains of the seniors, he will definitely not be able to free up his hands for the time being, and when he is free, he will definitely be able to make the results casually.

Now, sure enough.

"Well, it's already been made, but ......" Yu Cang's brows furrowed slightly, as if he was feeling it carefully, "The characteristics of this kind of soul card seem to be a little different from what I imagined." ”

Lin Yunqing immediately looked at the computer on the side, and after seeing the data on it, he also nodded: "...... Truly. Senior, the data shows that there is no change in your current mental stress occupation, but ...... The upper limit of the soul energy well is a little less. ”

Hearing this, Yu Cang sighed, and a look of "sure enough" flashed in his eyes.

On the side, Lin Yunqing's eyes became brighter and brighter after carefully reading the data on the computer.

"I see! Senior, is this how you solve the problem......"

The characteristics of spell cards are obvious, they have a short duration of effect, and they can do the most with fewer souls.

The pure spell flow can still exist, and occasionally play the basis of competition, because the spell flow does not take up much mental pressure, which makes the soul energy of the spell flow user recover quickly, and there is enough soul energy to cast spells to solve the field.

But in fact, the mental pressure of the spell card is very high, but the mental pressure of the spell card only acts on the moment the soul card is activated.

At this moment, the spell cards will directly stuff a large amount of mental pressure into the brain, and some spell cards can even be directly filled, or even exceed the upper limit...... But only for a moment, after activation, the mental stress will return to normal.

Fortunately, although the instantaneous mental pressure is very high, in this case, the soul card master can bear it normally.

The mental pressure tolerance of the soul card master has a certain elasticity, if it exceeds a lot of mental pressure in an instant, as long as this time is not long, then there will be no problem.

The greater the mental stress, the shorter the time requirements.

This feature was actually used by Yu Cang at the beginning.

At the beginning, Yu Cang followed Gu Jieshuang to the Bloodline Empire, and when facing Youqi, the Dragon Maiden Qi'er was manipulated by the Weeping Girl to stimulate the world-level spell card Bitter Weak Ascension in a very short period of time, thus gaining the power to hurt Youqi.

This time is only 0.02 seconds, which is still because the bloodline space is relatively special, there is no physical limitation, and it can explode with all its might.

The principle of the spell card is like this, when it is activated, there will be a high mental pressure, but the time is short, even if the mental pressure is close to full before activation, it can be activated.

In Lin Yunqing's conception, if the spell card is turned into a perpetual spell card, then the high mental pressure at that moment may become permanent...... In this way, it is somewhat not worth it.

The problem was so fatal that she couldn't even think of a solution that Ikuang would use.

But now, she's finally seeing the answer.

"Can you actually change the cost...... It's really an unbelievable train of thought......" Lin Yunqing's tone couldn't help but carry undisguised admiration.

No matter what soul card is, as long as it persists, it needs to pay a certain amount of resources. In this respect, Perpetual Spell Cards are completely different from other Soul Cards!

Other soul cards require mental stress, while perpetual spell cards pay the upper limit of the soul energy well!

It's a small change, but the benefits are huge.

The most classic thing is that it doesn't take up mental pressure, and the perpetual spell card can really exist forever! Worthy of the name of "sustainability"!

Moreover, this trait means that even if it is maintained all the time, the soul energy recovery rate of the Soul Card Master is normal, and it is completely normal to fight - this way, almost every deck can add one or two perpetual cards without affecting the normal operation of the deck at all!

There is no way to add a perpetual spell card, maybe only Yu Cang is like this, and the lower-level key soul card actually needs a whole tube of soul energy card deck.

Yu Cang couldn't help but sigh.

Who knows.

I really don't blame him...... The Dictatorial Ritual Sword does not have the side effect of reducing the upper limit of soul energy.

However, it seems that this may just be the unique feature of the Dictatorial Ritual Sword as a connecting spell card.

The universal laws that I have summarized by myself, at least in the calculation, most of the perpetual ones still have to be observed.
