This underground was discovered by several people of the free venerable.

They thought it was a Buddha devil court, but Xiao knew it was definitely not a Buddha devil court.

The real Buddha and devil are in their own hands.

Besides, Xiao Naihe has been inherited by the Buddha and the devil, and basically has been inherited by most of the Buddha and the devil country. Even if there are still the inheritance left by the remaining ancient demons and ancient Buddha experts, it must be far less than Xiao Naihe.

But this place, since it is not a place of Buddha and devil, what is it.

You know, at that time, it was opened by several people of the free venerable through the seed of cause and effect.

This place must have something to do with the Buddha and devil Kingdom, but Xiao doesn't know what it is.

The three of them went deep into a cave underground.

The underground looks like a lot of bends, but if you count it up, it's really a little big.

Xiao Naihe went under the ground and put his mind into the cave.

Just now the mind got into it, and immediately it seemed as if it had met something, and it bounced back its mind.

Then, what appeared in front of him was a wall. I don't know what it was made of, but it had a mysterious cyan yellow.

It's slightly crafty. It's obviously not natural. It must be written by someone,

Xiao glanced at it. His mind kept drilling around the wall, but he couldn't get in.

"It's interesting that the mind can't get into the wall."

Xiao Naihe was curious. There was such a thing under the ground. It was obviously strange.

As soon as he heard Xiao Naihe's words, he was also a little curious. He quickly released his mind and echoed on the green and yellow wall.

But in any case, his mind could not penetrate into the wall. As soon as he entered the wall three inches, he was immediately bounced back. There was no way.

Seeing this situation, he also breathed out: "indeed, I have never heard of such a wall in my training for so many years."

"This wall is not made of nature. It must have been written by someone. The main reason is that the material of the wall is a little strange."

Xiao Naihe did not find information about this wall through memory of the Lord of the heavenly abuse.

Empress Qiong, who had been following Xiao Naihe, suddenly said, "is it xuantie, the sword mother?"

"Sword mother black iron?"

What is that?

Xiao Naihe had never heard of such a thing, but from the tone of empress Qiong, it seemed that this woman knew something.

"Dark iron, the sword mother? Xiao Qiong, when you say so, I remember. It's really a bit like it."

He patted his head and seemed to think of something.

Only Xiao Naihe looked strange and couldn't help asking, "what is this dark iron?"

"Young master, don't you know xuantie, the sword mother?"

"I don't know."

"The dark iron of the sword mother is a mysterious iron in ancient times. It is said that it came from outside the sky and can be used to refine all kinds of magic weapons and Taoist instruments. At the beginning, our ancestors in the ancient kingdom of spring also obtained the dark iron of the sword mother. Just the size of a thumb, they can make a 3000 Jin sword. After refining, it turns into a holy instrument, indestructible and powerful."

Just the size of your thumb, you can refine it into a 3000 Jin sword?

That's great.

"Unfortunately, this sword was lost somewhere during the war."

Speaking of this, even empress Qiong's tone revealed a kind of regret.

Xiao didn't know how powerful the dark iron sword mother was, and he didn't feel much.

But empress Qiong, they have been in contact with the dark iron of the sword mother. Now they see this wall. Through some characteristics, it is not difficult to find that it is the same as the dark iron of the sword mother.

"There must be something strange behind the wall. Otherwise, the dark iron of the sword mother is indestructible. When it is made into a wall, it has no purpose other than to block outsiders."

"It seems so."

While Xiao Naihe was talking, a black stone suddenly appeared on his head.

This stone is Xiao Naihe's magic weapon dragon stone.

The Jielong stone has been repaired in the starry world. Now it can be taken out and used.

"Childe, are you here?"

"Needless to say, it's natural to break the wall directly."

"What?"

As soon as they heard this, empress Qiong and Yuzi couldn't help taking a breath of air conditioning.

Good guy, this is an indestructible sword mother black iron.

At the beginning, their ancestors in the ancient spring country were able to make swords and sacred objects the size of a thumb.

It's almost impossible to leave a trace on such a big black iron, let alone break it.

"Yes, you two return first, so as not to affect it."

Chen Zi pulled empress Qiong back quickly, but his eyes were fixed on Xiao Naihe. He wanted to see how Xiao Naihe broke the black iron of the sword mother.

As soon as the "Jielong stone" in Xiao Naihe's hand rotates, the atmosphere around him suddenly becomes extremely depressed.

As if thousands of pressure came, the whole underground became very dull.

Even she can feel her body. It seems that she is oppressed by something weighing tens of thousands of kilograms and can hardly extricate herself.

But the lady Qiong beside her looked calm and looked curious at her actions.

"What's going on? Can't little Joan feel it?"

"What do you feel?" asked little Joan subconsciously.

Suddenly, his face changed.

Empress Qiong really didn't feel this pressure. You know, under such pressure, even the strong one who has just stepped into the middle of the holy statue can't help feeling creepy.

But empress Qiong's cultivation is so low that she can't feel such pressure. It's obviously very strange.

However, if this pressure is suppressed, empress Qiong must be the first one who can't bear it and will be directly bloody.

But now empress Qiong has nothing at all, which shows that this force is really useless to empress Qiong.

Is this kind of pressure only for those who practice the road?

"Jielong stone, open."

Yes, the ancient clan's Avenue from the Jielong stone forced this wall to be pressed down by the town.

The power of the dragon stone will not be felt by a woman with few accomplishments like empress Qiong.

Therefore, He Zi was the first to feel such power suppression.

Just when he was almost unable to resist, the iron wall formed by the black iron of the sword mother suddenly clicked, and a crack was directly formed under the impact of Jielong stone.

"Darling, the black iron of the sword mother can crack. It's amazing."

She was shocked.

Xiao was not only extremely powerful, but also the magic weapon in his hand. Otherwise, how could he have knocked out a long crack in the wall just now.

You know, you can't even do this.

But as soon as the crack appeared, Xiao Naihe also drilled through the crack and entered the wall.

Just after they went in, suddenly a burst of fire flickered around, like phosphorous fire, lighting the whole cave.

What appeared in front of Xiao Naihe was a strange ball, which seemed to hide a small world.

With the memory of Xiao Naihe, he finally thought of something.

"Is this one of the holy treasures of the ancient demon family, Shenxiao jiulei tower?"

Xiao Naihe gets the Buddha and devil Kingdom, which is naturally the memory of the Buddha and devil kingdom.

From the memory of the Buddha and devil Kingdom, Xiao Naihe also knew a lot about the Buddha and devil kingdom.

Among the ancient demons, there was once a holy treasure. The name of this holy treasure is Shenxiao jiulei tower. It is one of the rare nine grade holy treasures of the ancient demons.

Such a holy treasure is equivalent to the dragon stone and the ancient temple.

However, Jielong stone has excellent space ability. Although it is not as mysterious as the original void door, it is almost the same.

The ancient world hall, to be exact, can be said to be a holy treasure, but it can not be said to be a holy treasure.

Jielongshi also has strong combat capability.

The combat capability of the ancient world hall is extremely general.

It seems that there is only one way for Xiao Naihe to deal with some experts with extremely strong accomplishments and use the ancient world hall to deal with others.

That is to use the strength of the ancient temple to directly hit others.

The best thing about the ancient world hall is its strength, which is comparable to a continent.

Imagine how Xiao could hit people with the ancient world hall, which would be equivalent to hitting people with a continent. What a terror it would be.

However, such treasures as the ancient world hall can not be used as weapons after all.

This Shenxiao jiulei tower is no worse than the ancient world hall in strength, and even better than the ancient world hall in some aspects.

"I see. At the beginning, several strong men of the ancient demon family brought out the Shenxiao nine thunder tower to deal with the will of the eternal world. Later, as soon as these people died, the Shenxiao nine thunder tower naturally fell here."

Even in the realm of Buddha and devil, there are no more than two magic weapons at the level of Shenxiao jiulei tower, and one of the two was handed over to Yun Weixue, so that she can protect Yantian Pavilion while protecting herself.

Another thing is the Sacred Heart temple.

The Sacred Heart Temple must not be taken out at will.

If you get the nine thunder pagoda of Shenxiao, you can avoid the embarrassing situation that Xiao Naihe can only use the holy weapon of the ancient world hall, which has little combat ability, as a weapon.

"This place seems to be a pagoda. Is there a pagoda space below the cave?"

He Zi's mind went inside and outside the cave and saw Xingtai City of Shenxiao jiulei tower clearly.

But he didn't know about Shenxiao jiuleita.

Suddenly, he saw how Xiao could do it. He didn't know what he was doing. He stood still, as if he was talking and didn't know what he was reading.

"Young master Xiao, what are you doing?" asked empress Qiong subconsciously.

He gave Xiao a deep look and suddenly thought of something. "Young master Xiao has a lot of secrets. There must be a reason for him to do this. Maybe it has something to do with this place."
