The presence in the sutra can consume three kinds of energy summoning.

The first is the soul of a powerful demon. The second type is the power of will, that is, the power of incense and the power of faith. The third is the free point.

Depending on the strength of the target, the length of the advent time is different, and the cost is also different.

For example, the bones of the Horned Demon Emperor sealed on the first page of the Buddhist scriptures, and the demon gods and machine spirits on the second page.

The strength of the two realms is different, and the price is also completely different.

The former is just the skeleton that produces consciousness, so it is only the peak existence of Tiangang.

Although the latter has also consumed each other over the years, it is the ontology, and it is a whole great realm higher than the peak of Tiangang.

Moreover, when the latter uses the Demon God Temple, its strength will increase, but the consumption will be greater.

But even the Horned Demon Skeleton requires ten Earthshatter Spirits, or ten units of Faith Power, or ten Freedom Points to summon.

And it's only been around for a minute. For each additional minute stayed, the consumption is doubled.

Demon gods and machine spirits, summoning one alone, the cost is tenfold increase, at least a hundred free points, or the same energy of demon souls and the power of faith.

If the two of them are together, or even use the Demon God Temple, they will need 200 or 300 free points or ......

"Damn, that's too dark!"

After Zhang Feng realized this, he couldn't help but burst into foul language.

Sure enough, there is no free lunch in the world, and the price required to summon a terrifying existence is just as terrifying.

Since he came to the Central Planet, it has been relatively easy to obtain the heavenly and earthly treasures that can be absorbed, and he often has big gains.

But I still can't afford to use this sutra.

The only thing to be thankful for is that if he cultivates to a high level in the future, it will be relatively easy to obtain demon souls and the like.

In addition, even now, if he had accumulated for a while, he would be able to summon the skeleton of the Horned Demon Emperor once and a half.

Although it cannot be used freely, it can be used as the strongest hole card.

"Well, it's actually pretty good, in my current situation, the skeleton of the Horned Demon Emperor is enough to sweep any enemy, ten free points, ten demon souls or something, in fact, I can barely afford it. ”

After thinking about it, Zhang Feng immediately calmed down and became happy again.

With this sutra present, he immediately developed an unprecedented sense of security.

Otherwise, even if Jiang Taixuan and the Sect Leader pay attention, he is still full of a sense of crisis, because the real master among the enemies really has to make up his mind, and if he is desperate, he can be completely killed.

He is still alive now, but he has not really been taken seriously by the Tiangang Realm, or even stronger enemies.

Freedom, Demon Soul and Faith Power, Zhang Feng finally decided to give priority to the use of Demon Soul.

Although the freedom point is the most convenient, it is needless to say how precious and useful it is.

The power of faith, he also relies on the earth to provide, there are no statues or anything here, he can only rely on the practice to absorb and directly refine, in addition, he does not have a special means to collect the power of faith.

Only the demon soul, it's not much use, and it's the most convenient to collect, so when you kill a demon, you can grab it by the way.

Even, if you kill the demon and don't collect the demon soul, there is a chance that the demon soul will dissipate on its own, which is a waste!

Thinking of this, Zhang Feng even felt a little regretful: he didn't know that he had missed the black-robed envoy and those souls who were killed by the Demon God Temple in vain.

Fortunately, there are many powerful demons on the central planet, and they are all common enemies of mankind, and you can get other gains if you kill them.

"Well, I'll use this later. ”

Zhang Feng probed his divine thoughts into the storage ring, and quickly found a small triangular banner with black smoke and blood.

This small banner is called the Ten Thousand Soul Banner, which is a superb spiritual weapon refined by demons, and it is obtained from the storage equipment of one of the demon demons killed by the Demon God Temple.

It's just that Zhang Feng didn't have much interest in this thing before, so he casually threw it in the depths of the storage ring, which just came in handy at this time.

This Ten Thousand Soul Banner is already an ownerless thing, and it is just a spiritual weapon, Zhang Feng accepted the Buddhist scriptures, and flicked his fingers out a colorful true evil, this demon spirit weapon immediately sizzled, green smoke rose, and it was completely refined in a blink of an eye.

At the same time, Zhang Feng also had a mysterious connection with this little flag, and found that except for some special spirit arrays, they were all specially collected from the depths of a dangerous place called the Demon Abyss, and when the soul was in it, it could move freely, and condensed its body with the magic mist, like a fish in water.

When you want to attack, the demonic mist will also pour out, so that the soul in it is like a tiger with wings, and even the general physical damage is not afraid, and it can be quickly recovered if it is shattered.

In addition, the more resentful the soul is in it, the better, so the most favorite thing for demons to refine this kind of spiritual weapon is to torture and torture human beings and other lives, so that they are full of resentment and then collect it.

Even ordinary souls without resentment, under the influence of the demonic mist, will become ferocious and bloodthirsty, and after being released and eaten a few times by humans, they will further transform into resentful spirits and ghosts.

In addition, this thing also has a drawback, that is, every once in a while, its owner needs to feed and sacrifice with a large amount of his own blood, otherwise, once the soul is released, there is a high probability that its owner will be eaten first.

Zhang Feng just wanted to use it to collect souls, and naturally he couldn't bear these problems, and the refining techniques of this thing, and even the spirit array, demon fog and so on, were too rubbish, and Zhang Feng couldn't stand it at all.

Moreover, this thing looks evil, and it is not suitable for him to use in public.

So, after determining that because the original owner died, the souls had already died together, and after it was already empty at this time, Zhang Feng immediately made drastic changes to this thing.

First of all, the material, except for some necessary ghost willow yin wood and the like, the rest are directly replaced with treasure-level materials.

In this way, this ten thousand spirit flags immediately became more than one grade stronger.

Then there is its appearance, a small pennant or something, too much of a sissy, directly transformed into a big one, which looks quite domineering.

In the end, it was one of the formations that was also upgraded by Zhang Feng to the peak of the lower grade of the treasure level, and the entire Ten Thousand Soul Banner immediately underwent an essential change and became a low-grade treasure.

But the aggressive, polluting or something was directly erased by Zhang Feng, and the demonic mist was also used by Zhang Feng as a material to preserve the soul.

The problem of needing his own blood to sacrifice is naturally gone, because Zhang Feng doesn't need to be locked in it at all, and his soul becomes a resentful ghost and comes out to kill the enemy or something.

In terms of collecting souls, Zhang Feng has greatly strengthened, and there is no need to take the initiative to activate the spirit array, as long as he carries this thing on his body and does not hide it in spatial equipment such as storage rings, except for human souls within a radius of a kilometer, he will be included in it by himself.

If it is actively triggered, it can produce an invisible huge spiral nest, which will directly swallow all the souls outside the human body within a radius of ten miles.

After such a series of transformations, this Ten Thousand Soul Banner immediately changed its appearance, from an evil weapon to a container dedicated to collecting and preserving souls.

At the same time, the appearance of this Ten Thousand Soul Banner is also half of the black qi and blood light.

In addition to the domineering style, if the average martial artist does not have special detection methods, he can't even see that this is a low-grade treasure, and it is even more impossible to think that its original form is an evil thing.
