This Immortal Demon Tower is not only a magic weapon of the Sun, but also has a lot of powerful formations in it, although the realm of this black-robed man has broken through to the early stage of integration, but Cheng Yu is able to use the formation to lower the realm of the other party.

So Cheng Yu sacrificed the Immortal Demon Tower, ready to kill this guy with the Binding Realm Extermination Technique!

Seeing that this Immortal Demon Tower suddenly flew into the air, covering the black-robed man under the golden light of the Immortal Demon Tower, Cheng Yu was overjoyed in his heart, as long as he entered this formation, it would be difficult for this kid to escape.

The black-robed man saw that he was covered by the golden curtain scripture of this magic weapon, and secretly said that it was not good, and he fell for this kid. So he hurriedly rushed towards the golden curtain, wanting to force his way out!

Boom!

However, it is easy to enter this Immortal Demon Tower, but it is difficult to get out. At least so far, only Situ Yongkang used the Burst Charm to blow up the defenses of this Immortal Demon Tower, and finally escaped.

Although the strength of this black-robed man is strong, it is not an easy task to escape from this Immortal Demon Tower.

The black-robed man first hit the golden curtain wall several times, but there was no way to rush out. So he began to attack the Immortal Demon Tower directly.

With the strength of the black-robed man, Cheng Yu was really a little worried about whether this guy would break through the defenses of the Immortal Demon Tower. Seeing that the Immortal Demon Tower was a little shaky under the attack of the black-robed man, he was even more worried in his heart, so he continued to pour spiritual energy into the Immortal Demon Tower, which made it stabilize.

Seeing that the black-robed man hadn't broken this magic weapon like this, he suddenly felt a little anxious in his heart, and hurriedly attacked the Immortal Demon Tower with his Yin Spirit outside the Immortal Demon Tower.

In his opinion, attacking this magic weapon from the outside seemed to be much more difficult than breaking the magic weapon from the inside. The yin spirit knew what his master was thinking, so he quickly rushed towards the Immortal Demon Tower.

This Yin Spirit was in the middle stage of the merger, and the power of that attack should not be underestimated, it slammed into the Immortal Demon Tower, and the black-robed man also took the opportunity to attack it at the same time in the Immortal Demon Tower.

In his opinion, he and his Yin Spirit internal and external attacks, it will definitely be able to break this magic weapon.

Seeing that the Immortal Demon Tower was crumbling, Cheng Yu was anxious, and more spiritual energy poured into the Immortal Demon Tower. At this time, the golden light of the Immortal Demon Tower was flourishing, and the yin spirit was illuminated by this golden light, and it was directly knocked out.

This immortal demon tower was originally a thing of the sun, and this golden light had the effect of suppressing evil and exorcising demons, and this yin spirit was naturally afraid. This yin spirit was driven away, and Cheng Yu's pressure suddenly decreased a lot, and he hurriedly prepared to open the formation of the Binding Realm Extermination Technique.

Forty-nine runes flew out of the Immortal Demon Tower at once, and they were attached to the golden curtain wall.

At this time, the black-robed man was even more surprised in his heart, seeing this inexplicable change, he knew that Cheng Yu must be brewing something bad again.

Thinking of this, before he could wait for those runes to take effect, he suddenly released his soul-sucking bats, all of which were concentrated on that golden curtain wall, and suddenly the curtain wall in that place became dim, much darker than the golden curtain wall next to it, and it seemed to be thinner.

The stomachs of those soul-sucking bats slowly bulged, and it turned out that they were absorbing the energy of the curtain wall on top of the curtain wall.

Cheng Yu was shocked when he saw this, knowing that these soul-sucking bats could not be ignored, these guys looked small, but when they absorbed energy, they were larger than the belly of an ordinary monk.

Hurriedly, a large amount of spiritual energy poured into the Immortal Demon Tower again, and as a result, the golden curtain wall began to light up again, but compared to the golden curtain wall next to it, it was still a little duller, but it had already played a role.

Seeing this, the black-robed man was furious, and released a batch of soul-sucking bats again, which were once again attached to the curtain wall.

At the same time, the forty-nine runes suddenly shot out one after another, and the forty-nine runes were connected to each other through these silky rays of light.

"What's going on?" At this time, the black-robed people were shocked, wasn't he in the merging period?

However, before he had time to think about it, the Immortal Demon Tower suddenly flew out of a bunch of runes, and at the same time, thunder and lightning began to appear under the Immortal Demon Tower, and there was a boom, and the black-robed man knew that the killing move was approaching, and his heart was even more anxious.

But when I saw that the wall of the scene still couldn't be broken, I just hoped that my soul-sucking bat would suck faster.

Seeing that the purple heavenly thunder under the Immortal Demon Tower was condensing more and more, and a heavenly thunder was above his head, the black-robed people were even more anxious.

He can't even manage so much, although he lost a lot of soul-sucking bats because of the battle with the Kunlun four people last day, and he has so many soul-sucking bats left now, but his own safety is more important.

As long as he is alive, there is a way to cultivate more soul-sucking bats, thinking of this, he did not wait for the soul-sucking bats to continue to absorb energy, but chose to let these soul-sucking bats explode by themselves!

Boom Boom!

There are so many soul-sucking bats, there are at least thousands, and the energy absorbed in their bodies is equivalent to the energy stored in the dantian of a primordial infancy monk.

With so many soul-sucking bats exploding at the same time, the power can be imagined. In addition, the curtain wall was already sucked by them much thinner than the next one.

As a result, the curtain wall was suddenly exploded, and although the black-robed man was heartbroken that he had lost so many soul-sucking bats, he had a chance to go out.

I didn't think about it so much, and in an instant, it turned into a puff of black smoke and escaped from the gap in the wall.

At this time, the huge heavenly thunder that Cheng Yu was brewing happened to be split, but there was no shadow of the black-robed man there, this heavenly thunder just split into the air!

Cheng Yu secretly said that it was not good! This guy was so willing to give up so many soul-sucking bats and chose to break through the defense of the Immortal Demon Tower.

The magic trick in Cheng Yu's hand changed, and the Immortal Demon Tower moved again, wanting to cover the black-robed man in it.

But after eating a trench and growing wise, how could the black-robed man be covered by him so easily?

"Hmph! carving insect skills, how can I be fooled by you again!" The black-robed man hated Cheng Yu at this time, because of his carelessness, he actually lost all the few spirit sucking bats he left.

I saw the black-robed man carrying a long knife and slashing towards the Immortal Demon Tower, in the Immortal Demon Tower, it was difficult to exert his strength, and he was inexplicably demoted by one level.

But out of this Immortal Demon Tower, his strength was immediately restored, and this knife went down, and the Immortal Demon Tower was split away at once.

Cheng Yu was also depressed, seeing that he was about to succeed, but he didn't expect the black-robed man to act so decisively. So many soul-sucking bats say sacrifice is sacrifice.

Now that this guy is out, there is no way to defeat him with his current strength!
