"Sonorous!"

The light palm collided with the sword rainbow, and there was a sound of sword roaring, but the split empty handprint was difficult to restrain the sword rainbow. The sword rainbow is transformed by the dragon horns of the bone dragon, condensing all the essence of the bone dragon before its death, even if it is the domineering of the empty handprint, it cannot be shaken at all.

"Sonorous!"

The little demon fairy covered a sword rainbow with a cold knife made of petals, and the sword rainbow made a buzzing sound, as if trying to escape.

Zhuge Buliang shot out the crack handprint again and again, and several light palms restrained another sword rainbow.

But at this moment, the black tower burst into a sky-high light, and countless undead creatures instantly turned into ashes. The undead creature woman who had previously controlled the bone dragon flew out, and the black mist on her body became much fainter.

The two sword rainbows that were bound by the little demon fairy and Zhuge Buliang rose into the sky, broke free from the restraints, and rushed towards the undead woman. The undead woman's hand pulled, and two sword rainbows rushed towards the black stone on the black tower.

"Boom!"

The ink-colored brilliance rioted, and an earth-shattering thunder sounded in the sky above the Divine City, and the black stone shattered in response, and a violent energy shock wave surged mightily, and the sword rainbow turned into two dragon horns was also bounced out and flew into the distance.

Four divine lights rushed out of the four stones, sweeping towards the undead creature woman who was riding the bone dragon, and under the interweaving of the four divine lights, the undead creature woman turned into ashes and scattered.

At the same time, the brilliance of the remaining four stones dimmed instantly, and without the black stone, the seal guarding the Black Tower seemed to be incomplete.

At this time, the four stones guarding the Black Tower also flew back into the Black Tower, and the Black Tower fell silent instantly. The undead stopped their attack and let out a roar of annoyance, and finally, all the undead tore open the ground and burrowed into the cracks, and a large area of black qi converged, and the city once again returned to calm.

As soon as the wind blew, the traces of the battle were covered by the bone meal all over the city, and everything seemed to have never been born.

Only the black tower still stood, straight up into the sky, like a black sword.

"These undead creatures only seem to attack when the large array guarding the Black Tower appears. Zhuge Buliang muttered.

The little demon fairy nodded and said, "That undead creature just now has been wiped out, presumably the dragon horns of that pair of bone dragons are already ownerless, I will go and subdue them." With that, the little demon fairy rose up in the sky and rushed in the direction where the dragon's horns flew away.

Zhuge Buliang smiled bitterly, and now the undead creature retreated, and there was no longer any way to stop it, Zhuge Buliang walked towards the black tower. Standing at the bottom of the Black Tower, looking at the straight and towering Black Tower, Zhuge Buliang was stunned for a while, what secrets are there in this Black Tower, which makes these undead creatures so obsessed.

At this moment, Zhuge Buliang saw several black gravels not far away, which were left over from the previous black stone. Able to protect the Black Tower, these stones naturally have an extraordinary origin, but unfortunately they have been broken.

Zhuge Buliang came to these gravels, and the flying bone powder had already buried most of these gravels, and the black gravel looked ordinary at the moment, no different from ordinary stones. Zhuge Buliang kicked the gravel with his foot, and at this time, a rectangular stone more than a foot long came into view.

This black gravel is different from other gravel in that the fractures are very neat. It stands to reason that the black stone was shattered, and the broken stone was scattered into uneven and uneven parts, but this one was the only one that was different, and the incision was neat, as if it had been cut by a sword.

Zhuge Buliang bent down and picked up this flat black stone, and his hand was heavy, pitch black as ink, except that the incision was very smooth, there seemed to be nothing special.

Zhuge Buliang weighed it in his hand, and said with a smile: "Why does it look like a brick......

At this moment, Zhuge Buliang's Beidou Divine Acupoint in his body moved, and he hurriedly looked inside, and as a result, the seven Acupoints bloomed with dazzling light.

Zhuge Buliang suddenly focused his gaze on the stone in his hand, which looked like a brick, and secretly said in his heart: "Could it be that this stone caused the reaction of the seven divine acupoints?"

A sound of breaking through the air sounded, and the little demon fairy flew from afar, with a look of joy on her face, it seemed that she had already succeeded in the horn of the bone dragon.

Zhuge Buliang hurriedly put the black brick into the Qiankun bag, pretending to be fine.

"What are you hiding, take it out!" The little demon fairy's divine sense was so keen, and he immediately saw Zhuge Buliang's abnormality.

Zhuge Buliang has lewd the little demon fairy thousands of times in his heart, this girl is too desperate to do things, but he can only think about it. Seeing the little demon fairy's unkind eyes, Zhuge Buliang could only take out the black brick and said, "This is a fragment of the black stone, you can take it if you like." ”

The little demon fairy took the black brick, looked left and right for a while, and there was nothing strange about it, and pursed his lips and said: "The black stone is black and black, it is ugly and dead, who is rare." After that, he threw the black brick to Zhuge Buliang.

Throwing the black bricks into the Qiankun bag, Zhuge Buliang looked around and said, "Do we still want to stay here?"

"Of course. The little demon fairy said: "There are many secrets in this divine city, especially this black tower, maybe there is some amazing magic weapon in it." ”

Zhuge Buliang pursed his lips and was about to say something, but at this moment, the Divine City throbbed, and the straight and towering black tower trembled violently, and a black light rose to the sky, and the entire Divine City was shaking, as if a wild beast had awakened.

This is an underground world, and the sky above is covered in ice, but the black light bursting from the Black Tower breaks through the ice and penetrates the sky.

"Boom!"

The Black Tower seemed to want to rise from the sky, and the inky light surged, and the entire Divine City seemed to be on the verge of collapse at this moment, constantly shaking.

A devastating black light rushed out from the Black Tower, as if a thick celestial power was shrouding it.

"Suffer, leave!" the little demon fairy exclaimed, and quickly sacrificed the lotus platform, and the lotus platform turned into four, and flew away from the divine city with the little demon fairy.

"M!" Zhuge Buliang scolded secretly, this little girl was so unrighteous that she left alone.

Zhuge Buliang's swift sword rose up, and also flew towards the outside of the Divine City.

The light of destruction swept out of the black tower spread rapidly, some of the buildings in the city were collapsing, and the undead creatures in the underground let out a miserable roar, as if they were affected by the light of destruction. Zhuge walked without flashing his sword, and the light of destruction was behind him, like a hideous demon poking out the hand of death to him.

"You said you wanted to keep me safe!" Zhuge Buliang transmitted the message to the little demon fairy.

"We split up and gathered at the Ice Grave. The voice of the little demon fairy came from afar.

Behind, the entire Divine City was shrouded in black brilliance, and countless miserable roars came from the black area, and the undead creatures lurking in the Divine City struggled under the terrifying light of destruction. Moreover, the light of destruction continues to spread across the Circle.
