"Twin Towers!" came the fairy sister's cold voice.

Zhang Ning was stunned for a moment, and then came back to his senses, this is the fairy sister answering herself, originally along the way, she ignored her question, and the fairy sister's coldness has made Zhang Ning have no hope of communicating with her. I didn't expect her to really answer herself.

"What kind of place is the Twin Towers?" Zhang Ning had an opportunity, of course he would seize it, and then asked.

"It is one of the passages for the invasion of the Demon Realm, it was originally the passage between the Moro Realm and our cultivation realm, and after the Moro Realm was occupied by the Demon Realm, this became one of the places where they attacked our cultivation realm. The cold voice replied without the slightest emotion.

After Zhang Ning heard this, he chuckled in his heart, and said in his heart, something bad happened, this old guy of Qingyangzi actually asked the fairy sister to bring him here, what does he mean? Do you want to vote for yourself and kill a few people from the demon clan to show that you are not from that side?

He then remembered Yu Li'er's change of attitude today and yesterday, and the more he thought about it, the more likely it became.

He asked cautiously, "This, Sister Fairy, have people from the Demon Realm begun to invade this passage?"

Yu Li'er glanced at Zhang Ning coldly, just a glance, like a basin of cold water pouring Zhang Ning from head to toe. Zhang Ning felt that the fairy sister seemed to see through what she was thinking. The whole person is placed under a high-magnification microscope and is observed by the fairy sister.

"Ahem, I'm not afraid, I'm just asking, understand, know and understand, do you know yourself and your opponent and win all battles!" Zhang Ning explained embarrassedly. Although his words are very pale, he can relieve the embarrassment in his heart a little.

Yu Li'er ignored Zhang Ning and continued to fly.

Seeing the fairy sister turn around, Zhang Ning breathed a sigh of relief, and then scolded herself in her heart, why is she so uncompetitive, why should you be afraid of her.

The black clouds hung low, and between the lightning and thunder, a huge floating island suddenly appeared in the distance in the sky. flew closer, and Zhang Ning saw clearly that it was not one, but two floating islands connected together. A very large floating island has been formed.

Both floating islands are large, and the floating islands stand in the air in the shape of a shuttle. At the place where the two floating islands are connected, thousands of walls are erected, forming vertical cliffs from top to bottom, and between the two floating islands, several stone paths are formed. It's like a staircase in the sky. Two floating islands are connected.

From a distance, the two floating islands look like a huge crack, splitting a sharp head and belly wide island from top to bottom, forming the famous terrain among some of the earth's peaks—a line of heaven.

However, the sky here is more magnificent and more dangerous. Inside the sky, dozens of stone paths connect the routes of the two floating islands.

"Hack!"

A thick bolt of lightning slashed down on Zhang Ning's right side, shocking Jiang Cheng, who was looking at the first-line sky over there, half to death, his heart suddenly contracted, and then he relaxed violently. The process of extreme tension to relaxation really made Zhang Ning feel refreshed.

The lightning here is extraordinarily thick, and the energy contained in the lightning is fierce and vast, Zhang Ning knows that although he is now relatively good. But after being hit by that lightning, he was sure to finish the game, looking at Yu Li'er who was shuttling in the lightning without changing her face, Zhang Ning couldn't help but secretly admire. Although people may have experienced this situation many times. Maybe people have lived in this environment since childhood. But he still admires it.

It's getting closer to a glimmer of time. These two floating islands are obviously different from the other floating islands that Zhang Ning has seen.

These two floating islands look black from a distance, unlike the floating islands over there, there are forests, green trees, lakes and grasslands, these two floating islands, like two iron lumps, the dark color gives people a feeling of oppression. And under the lightning and thunder, the surface of the bare floating island is a metallic stone.

When you get closer, you can see more clearly that these two floating islands are simply two huge stone lumps. Moreover, it is still a stone lump with a metal component. Just when Zhang Ning guessed where the passage was, Yu Li'er flew into the sky with Zhang Ning.

I didn't enter the first line of sky, I didn't feel that huge sense of oppression, and after entering, I looked up to the dark sky with no end in sight, and only a little light at the end proved that there was still a sky above. Surrounded by rugged cliffs, there is no end in sight below. There was only a vague darkness. In the middle of a glimmer of heaven. There are dozens of huge stone paths that connect the two sides. The distance between the two floating islands is more than a kilometer.

When people walk in the middle, they feel their own insignificance.

"Boom!"

After a burst of thunder, it began to rain in the sky, and as soon as it rained, the rain fell overwhelmingly, and there was not even a process from small to large in between. Raindrops bigger than beans are falling. The strange rocks that hit the cliff and spilled on the stone path of the sky.

The stone path is generally more than ten meters thick, and the surface of the stone path is very rough, and you can see that there are many cavities on those stone paths, and I don't know how they were formed. And Zhang Ning noticed that on the cliff, there were still many broken stone strips. Some stretched out thirty or forty meters and broke apart. Some broke off after more than a dozen meters. However, they all share the same characteristics.

That is, the damage is serious, and looking at the appearance of those stones, it is clear that many of them are damaged by external forces.

Looking at the countless broken stone paths on the cliffs on both sides, Zhang Ning thought of the invasion of the Demon Realm, and his heart couldn't help but feel a little heavy.

On the cliff, there are many caves, and from a distance, I don't know how deep it is. But I saw some stone paths connecting the caves. It must not be too shallow.

There are a lot of doubts in my mind. Zhang Ning just felt heavy and depressed.

The rain was fierce, but Yu Li'er had already propped up a golden True Yuan shield. Keep the rain out. The splash of rain Zhang Ning looked very beautiful inside, and the white shield was very conspicuous in this dark night. The flying sword under his feet is even more conspicuous in a bright gold.

Suddenly, Yu Li'er's cold voice came: "We have arrived!"

Zhang Ning was startled, and he felt that the flying sword began to fly towards a cave on a cliff on the right. The difference is that the cave is not dark and dark. Instead, it is lit up in white. In this dark color, this light is so obvious.

From a distance, Zhang Ning saw that in front of the cave was a huge protruding rock, on which a square had been cleared. In the square, there are several stone pillars standing, and the white light is emitted from the stone pillars. Slowly flying closer, I found that there was a fist-sized bead on more than a dozen stone pillars. And that light came out of the beads.

When it fell, Zhang Ning felt that this square was not small. The protruding rocks do not have stone paths to connect the two sides. It seems very abrupt.
