The formation is definitely a legendary tall and mysterious existence in the immortal cultivation world, and those who can deploy the formation can be called high-end professionals.

But in the same way, the formation is very demanding on the external conditions, in other words, it can only fight positional warfare, and it takes a lot of time to arrange in advance, consumes a lot of precious materials, and can be successfully arranged through a series of complex means.

So usually, the formations are used for defense, and they are all the patents of those high-ranking families, and a single person can't afford this kind of price at all.

The more powerful the formation, the more money it burns, and the more time it consumes, which is proportional, like the defensive formations of those big cities, they often need to be arranged for hundreds of years or thousands of years, and the amount of immortal stones and materials consumed is absolutely astronomical.

At this point, even powerful immortals are no exception, taking the Kunlun Forbidden Land as an example, in order to seal Kunlun's corpse, those immortals spent tens of thousands of years just arranging formations and prohibitions before and after, of course, the effect is really good.

As for wanting to arrange the formation in the battle of electric light, the head is definitely removed.

So Duan Heng was stunned for the first time after seeing the demon spit out the lapis bluestone, and then he almost had a bad belly, looking at that guy like a fool.

Are you kidding?

Not to mention that the demon has always been in arrears because of its congenital sake, let's just say that arranging a formation that can trap Duan Heng and pose a threat to Duan Heng will cost enough to buy four or five Duan Heng.

Yes, this formation is so cheating, the pay and income will never be balanced, even if you want to kill a little ant, you still have to pay a huge price.

Like the amozurite spit out by the demon, it is indeed very precious, and any one on the market can be said to be robbed. But just seven or eight bluestones want to arrange a formation to threaten Duan Heng, hum, that's a big joke in the world, less than three hundred bluestones can't be arranged in this formation.

In addition, this formation also requires a lot of other materials, as well as extremely complex calculations and derivations, and finally injects different evil qi or demonic qi. In short, the level of complexity can be maddening.

How much does this demon have to hate himself now to want to drum up a formation?

This IQ is really passing.

Duan Heng seemed to be watching the excitement, watching the demon keep spitting out the wind lapis bluestone, and then smashing it into the ground around him one by one, the action was very slow, the calculation was very rusty, just to determine the correct position of a wind lapis bluestone, he tossed back and forth hundreds of times.

More than ten days have passed, and the demon has only smashed less than eighteen wind bluestones around Duan Heng. It's as slow as an old cow.

But Duan Heng, who was originally counting on watching jokes, couldn't be happy anymore, although he didn't understand the formation, he could also see that even though the demon was very stupid, but for some reason, it would really arrange the formation, because just the eighteen wind bluestones smashed in the early stage could already continuously attract gusts of wind.

In this case, if Duan Heng still dared to laugh at the demon, he was a fool. Then he himself is a real big fool.

Maybe it will take years or even decades for that demon to completely complete the formation. But I'm really going to be finished.

"Damn, how could I meet such a freak?"

Duan Heng was depressed, it was really unlucky to meet such a stubborn demon, but he was helpless, maybe his primeval sword could break through the demon's defense. But the problem is that this demon's dodge speed is also amazing, this guy is already good at melee combat, once his own primeval sword can't hit, then the consequences will be even more serious.

A month later, there were thirty-six pieces of lazurite set around. This amount was naturally far from enough for the entire formation, but the violent wind that formed was obviously a lot stronger.

What surprised Duan Heng the most was that the speed and proficiency of the demon's arrangement of the formation were actually greatly improved, and if it continued like this, maybe in two or three years, this big array would be completely completed.

"No! ”

At this moment, Duan Heng finally noticed a trace of abnormality, because even if that demon was a freak, it would not go against the sky to such an extent, and it could arrange the formation to such an extent, this demon could not be mentally retarded, so it should be very clear that its approach was completely worth the loss, and it did not threaten it, from the instinct of the beast, all this was unreasonable.

So, I guessed wrong from the beginning, this demon is still mentally retarded, but it seems that something is secretly controlling it. It's just a puppet to be controlled, or a slave to be driven.

So, what's hidden in that canyon?

Suppressing the doubts in his heart, Duan Heng no longer tried to escape and break through, but condensed the ice shield day and night, absorbing spiritual dew, absorbing immortal qi, absorbing wind evil, and preparing for the upcoming decisive battle.

Isn't it just an arms race?

Moreover, Duan Heng was already sure that the unknown existence hidden in the depths of the canyon should be limited by some reason and could not take action in person, otherwise it would be so troublesome? In addition, there must be something on his body that was taken by others, such as the frost jade that day, from this point of view, it is no wonder that the other party wants to arrange a large array with great fanfare.

Time passed day by day, Duan Heng and the demon turned out to be at peace with each other, each busy, and the demon continued to improve the layout of the formation.

Duan Heng is stockpiling one four-grade cold ice shield after another, and every few days, he also releases the rain prayer technique, absorbs spiritual dew at night, and reserves immortal qi during the day.

And the wind formed by the half-cut formation was absorbed by him as a benefit.

Only regarding the Ancient Sword Demon, Duan Heng has not practiced it at all, this will be his killer weapon, and he can't startle the snake.

When three full years later, that big array has begun to take shape, and three hundred and sixty wind bluestones alone have been smashed, with Duan Heng's position as the center, the three wind tornadoes continue to circle day and night, and in this whirlwind, countless wind blades continue to unfold and cut, and the ordinary five-grade cold ice shield can only last for an hour under such a cut, and it will be shattered immediately.

What's worse is that because of the spinning of the wind dragon, these broken ice crystals will be quickly thrown into the air, giving Duan Heng no chance to use them at all.

In addition, this large array not only brought a strong wind, but also seemed to have a tendency to cut off the outside world, and at present, it was difficult for Duan Heng to absorb the immortal spirit qi and evil qi, and only the daily spirit dew was not affected.

This is just an unfinished formation, if it is completed, it will definitely be enough for Duan Heng to drink a pot.

To be honest, this matter has developed to such a weird level, Duan Heng can only smile bitterly.

Fortunately, in the past three years, Duan Heng was also well prepared.

He first seized the time to raise his cultivation to another level, that is, the Shang Shu position, not for anything else, just to expand the capacity of the Qinglong Immortal Ding, the capacity of nine thousand stones, and the immortal qi and evil qi under the reserve, which were very terrifying, enough for Duan Heng to persist for a hundred years.

Not only that, Duan Heng also used the rain prayer technique and the five-rank ice dragon bloodline to condense thirty-six third-grade ice shields for himself.

This is almost his ultimate ability, because of the cold and evil qi of the third grade, which can usually only be mastered by prince-level immortal cultivators.

In addition, he prepared a full thousand four-grade ice shields.

In short, it's crazy, there is no other means, it is defense, almost extreme defense, see who can survive whom?

In addition to this turtle defense, Duan Heng's other huge gain was that the wind was shattered, to be honest, at this moment, he didn't want to break out of the formation.

This is a great opportunity.

Everyone knows that the Storm Evil Qi is quite difficult to capture and refine, because this thing usually needs to fly tens of thousands of feet in the air to encounter.

Duan Heng has no wings, and it is difficult to encounter high-quality and abundant wind brakes on weekdays.

This windy array is like a pie falling from the sky.

Thinking about the unknown existence in the abyss canyon, he probably couldn't have expected that Duan Heng actually had the Qinglong Immortal Ding, as one of the most compatible immortal dings, it was not too easy to absorb the wind evil.

What's even better is that the unknown existence can't be there in person for some reason, so it can only manipulate the puppet demon to arrange the formation, and can't detect the subtle changes in the formation at all.

So in the past three years, Duan Heng's absorption of wind and evil can be called a feast.

He has gone from not entering the stream at the beginning, to the nine-grade wind brake, then the eight-grade wind brake, and finally to the current seven-grade wind brake.

Progress is so fast!

Of course, the Wind Brake of the Seventh Rank still has no use in combat, but it is definitely excellent for using it to cast the Wind Evil Escape Method.

It's a pity that at this moment, Duan Heng doesn't want to run away, although in fact he can't escape.

The wind tornadoes in the great array are constantly strengthening, and the number is also constantly increasing, from three wind tornadoes to five wind tornadoes, the time has passed a full five years, and the entire wind storm array is almost complete, and more than a thousand wind bluestones have been consumed.

This is definitely a loser.

But such a storm array, the power did make Duan Heng suffer in the first place.

The five windspouts swirled back and forth, varied, like the five rotating heads of an oversized electric shaver, and each windspout contained 3,600 wind blades, running unhurriedly, full of high-end artistic atmosphere.

Even if he stood on the enemy's standpoint, Duan Heng had to be amazed by this.

Two words, exquisite!

And under such a balanced cutting of the five wind tornadoes, the ice shield of the fifth grade is almost like tofu dregs, and the cold ice shield of the fourth grade is not ideal, it can be ground in an average of half an hour, at this rate, at most, a month, Duan Heng will have to die a little whine, and there is no suspense.

This is the power of the formation.

Even if it took a full five years, even if it cost a huge price, the lethality of this Wind Evil Formation was really not blown.

"Fortunately, Lao Tzu was prepared. ”

Duan Heng sighed with palpitations.
