Chapter 850, the Invincible Self

Zhou Yan kept engraving a series of mysterious formation patterns, and took out the innate Taiji formation diagram in his body. Zhou Yan felt that the other party should not have such an innate Taiji formation diagram.

But he still underestimated his inner demons, and the other party also had them, and it was a kind of Tai Chi array diagram with demonic energy, it should be called the innate Tai Chi demon diagram.

Moreover, the opponent's Tai Chi magic map is still rotating backwards, which is completely opposite to his Tai Chi array map.

This shocked Zhou Yan, who had never seen such a situation before.

Zhou Yan continued to attack the heart demon, and a void in front of the heart demon was opened. When Zhou Yan was surprised, powerful summoned beasts were summoned by the heart demon.

A giant dark dragon, roaring upwards, came out from the alien space, covered in a terrifying dark devilish energy. This is a very powerful dragon with a powerful aura. It turned out to be a demigod-level dark devil. dragon.

There was another roar, and a terrifying black flame appeared from another alien space, and a black unicorn that was also shrouded in magic energy stepped out from it.

This is a dark unicorn, a dark unicorn that has fallen into the evil way, and even the flames on its body have become magic flames.

Another sound of phoenix cries came, and a dark phoenix with overwhelming demonic energy also flew out of a space. This is a hell phoenix full of hell flames.

Afterwards, a three-eyed green ape, a four-armed giant, a one-eyed demon, and a dark black turtle...

Even Zhou Yan was stunned. He had indeed learned this type of summoning skill before, but he had never used it himself.

Zhou Yan was actually reminded of this kind of memory by his inner demon, so he also started to summon the same summoned beasts one by one.

The authentic summoned beasts also appeared from a certain void, such as unicorns, phoenixes, black birds, black turtles, immemorial blue dragons, nine-headed birds...

The inner demon learns from him. Similarly, he can also learn the inner demon. Anyway, if the other party knows it, he must also know it. It's just that there is no need to use it in many cases.

Fortunately, the heart demon can't summon the heroes of the territory to come out. This is to challenge the strength of two people, so Zhou Yan can't summon the heroes of the territory to fight. Otherwise, Zhou Yan really plans to summon some heroes to help him win this battle. .

This fight seems to have evolved into a competition of summoned beasts between the two, and it seems to be more about who summoned the summoned beasts.

Zhou Yan's spiritual power is too strong. After all, the mental power attribute has reached hundreds of millions, even if he wants to be weak, he can't be weak.

With the blessing of such terrifying spiritual power, both sides can summon a lot of summoned beasts. In a few hours, an army of summoned beasts has been summoned.

These are all summoned under the premise of the strong spiritual power of both of them.

But these summoned beasts also need to consume their mental power continuously. Zhou Yan has stopped, and the mental power of the heart demon is also as much as Zhou Yan.

After the mental power of the two was exhausted, they took out a pseudo-artifact level bow and arrow again and started shooting at each other.

A powerful arrow, full of the power of thunder, finally turned into a thunder dragon to attack the heart demon. The heart demon was also not weak, and released a dark thunder dragon to fight back.

"Boom!"

The dragons transformed by the two arrows collided together, and finally disappeared into nothingness together.

Zhou Yan continued to bend his bow and set his arrows, bursting out one after another, turning into powerful destructive arrows, trying to kill the opponent.

In the end it failed.

Zhou Yan has the blessing of the territory, and his resilience is astonishing. The heart demon is just like him, and his resilience is equally strong. If this continues, it will always be a draw.

Zhou Yan was naturally not reconciled, and continued to perfect the formation of his entire formation, and he carved out formation patterns one after another to supplement the entire formation.

One hour...three hours...ten hours...three days...

Zhou Yan didn't know how many tricks he fought with the heart demon, and he didn't know how many methods he used. Finally, on this day, Zhou Yan densely covered the entire sky with a super large formation, and then Zhou Yan started to activate the entire formation. To kill it completely.

"See how I can kill you!"

Zhou Yan is full of self-confidence. After spending so long in the formation, he can finally kill the opponent completely.

After the shocking formation was fully activated, it emitted monstrous energy fluctuations, and immediately released destructive energy, constantly attacking the opponent.

"Swish Swish Swish!!!"

Under Zhou Yan's control, one after another of destructive rays of light attacked the heart demon, but the heart demon possessed many means, and under the use of space ability, it disappeared in the blink of an eye.

When it reappeared, thousands of demons appeared, and then thousands of demons attacked Zhou Yan together. Zhou Yan could only use the power of the formation to destroy them all.

The next moment, the heart demon walked into the formation and started manipulating the formation to deal with Zhou Yan himself.

"What the hell am I..."

It was only then that Zhou Yan discovered that this formation can also be manipulated by the inner demon, because the inner demon can also use this formation.

Zhou Yan literally dug a hole for himself to jump into.

But Zhou Yan couldn't give the opponent a chance to control this formation, and began to fight fiercely with the opponent. Both sides were equally powerful and had the same means.

Even though Zhou Yan's strength has been greatly strengthened in the past few days, it is a pity that this advantage is still unable to defeat his demons.

Zhou Yan still doesn't know how to defeat himself. Anyway, he has tried all the methods and can't think of a better one.

During the battle with the heart demon, Zhou Yan also grew a lot and successfully hit the heart demon, but Zhou Yan found that his strength was too perverted, like Xiaoqiang who could not be killed, and his injuries recovered quickly unless It can be completely eliminated at once, otherwise it is impossible to completely eliminate the inner demon.

Zhou Yan was speechless. Even this formation could not deal with the demons, and was almost used by the demons. After spending a lot of time, Zhou Yan finally succeeded in regaining control of the formation, and began to use the formation to continue to attack the demons. attack.

The demon blindly avoided, and was finally hit by Zhou Yan, who was slightly injured, but he still couldn't do it if he wanted to kill the demon completely. The recovery of the injury was too fast, and coupled with the many methods of the demon, even Zhou Yan himself I don't know what ability the demon will use next moment.

The inner demon is very powerful, he walked into the formation again, and began to destroy the formation. This formation, which was so hard to draw, was destroyed by the inner demon little by little, and finally began to collapse.

Zhou Yan can only try to defeat the demon in other ways.

At this time, Zhou Yan thought of Xu Long's method of using formations to carve himself on himself, using himself as the formation, and then bursting out with stronger strength.

Zhou Yan began to try, although it was very slow, but as time went by, he didn't know if it was a day or seven days, Zhou Yan still successfully engraved himself on the formation, after starting, his strength increased greatly, and his combat effectiveness was greatly improved. After strengthening, he began to suppress the inner demons.
