Although it only showed a trace of authority, Si Kongming caught it very keenly.

On the contrary, Si Kongming's background is not small, but there is an extremely powerful master behind him.

Even the heavenly sages have seen it more than once, and even he has seen the scene of the heavenly sages fighting.

However, no matter how powerful the sages in the world are, they are not as powerful as the threat and terror just revealed.

There is only one possibility that is more unfathomable than the sages of heaven and the world - Ancient immortals.

"Is Xiao Naihe an ancient immortal?" when this idea came into being, Si Kongming couldn't help shaking and didn't dare to think any more.

"No, no, he is definitely not an ancient immortal. He is likely to have the treasure given by the strong ancient immortal, and even what the strong ancient immortal left on him."

Si Kongming calmed down slowly. Xiao Naihe's cultivation can't be fake. He must not be an ancient immortal.

He estimated that there should be a strong man at the ancient immortal level behind Xiao Naihe, or even Xiao Naihe's master.

Otherwise, you can't explain why Xiao Nai is in the second section of immortality, and you can kill the awakened God King.

The more you think about it, the more terrible it is. Si Kongming is both frightened and excited: "unexpectedly, the backer behind him is the strong ancient immortal. Let alone the ancient immortal city. Even if the whole eastern boundary is moved out, it is estimated that there are not many ancient immortals."

No wonder Xiao is not afraid of the Yan Family and even the Jinwu family. Only after the ancient immortal is strong can he have such confidence.

Xiao Naihe doesn't know the two thoughts in the hearts of Si Kongming and Dong Huang qianxuan, but even if he knows, it doesn't matter.

He can't stop the fairy rhyme just revealed by the fairy fetus. As long as they can't see the fairy fetus, they will inevitably associate it with the strong ancient immortals. Maybe there have been other speculations in their hearts.

"Just as I thought, the Taoist rhyme of Gu Xian is the key to open the 'southern sky six fold array'." Xiao Naihe couldn't help laughing.

He put away the immortal fetus and landed on the ground. At this time, Dong Huang qianxuan and Si Kongming looked at Xiao Naihe with some changes.

"The big guy is the big guy. Even the 'southern sky six fold array' can be opened." Si Kongming's tone became enthusiastic.

Donghuang qianxuan is not stupid. She just didn't turn her mind. Now as soon as she calmed down, she guessed something immediately.

Xiao Naihe glanced at their faces and said nothing. Instead, he said, "let's go in. After we open the border, we may attract other people's attention. Hurry up."

Sure enough, Xiao Naihe's worry is not unreasonable.

Just as the three of them stepped into the deep crack, several places in the ancient city suddenly issued a burst of pressure.

Several old immortals suddenly opened their eyes. A pair of eyes seemed to have insight into thousands of existence and passed through the ages.

"That array has been opened? Who is it? Unless the ancient immortal moves, it is impossible for someone in the ancient immortal city to open the boundary of the saint of the southern array."

"No, I have to go and have a look."

At this time, several figures came out from the ground and flew directly in the direction of Huangfeng valley.

In Huangfeng Valley, Xiao Naihe has entered the deep crack and into the closed small space.

After entering this small space, it is not as small as Xiao Naihe imagined, but has a different world.

In the small space, there is another small world, with mountains in front of us, and peaks like pillars of heaven rising up into the sky.

After crossing the river, it was a vast expanse, shrouded in thick fog, and no one knew what was inside.

But when Xiao Naihe locked his eyes in the distance, he had a strange feeling.

The four elephant Sutra in his eyebrow had a reaction.

"What's the matter? Has the four elephant Sutra responded? I'm afraid there's something not simple in it. It may have something to do with the four elephant Sutra."

Xiao was shocked.

The four elephant Sutra is not an ordinary thing. It is a relic of the era. The nine heavenly books and nine heavenly objects between heaven and earth are the core treasures of the era derived from other eras.

It is definitely not easy to cause the reaction of the four elephant Sutra.

"Shall we go in?" seeing Xiao's hesitation, Dong Huang qianxuan also hesitated.

Unconsciously, they slowly took Xiao Naihe as the core.

Xiao breathed out, suppressed the strange feeling in his heart, and said, "we've all come here. There's no reason to retreat. Let's go in."

Between speaking, the first is to enter the fog.

Donghuang qianxuan and Si Kongming can only follow in. It's a pity that they don't go in.

In the fog, there are still huge mountains, and the most towering peaks actually reach the zenith, as if standing on the top of the star river.

Donghuang qianxuan and Si Kongming stood in front of this peak and immediately felt an unspeakable shock in their hearts.

The majestic momentum of the giant peak seems to drive this heaven and earth. The natural environment shows the uncanny workmanship of this heaven and earth.

"There seems to be a huge monument ahead," Si Kongming said suddenly.

Sure enough, there was a heavenly monument under the giant peak, which seemed to stop both ends of heaven and earth and cut off the starry sky.

This celestial monument looks very awkward and strange.

Especially when Xiao Naihe approached, the monument suddenly moved by itself.

"Why..."

Countless veins suddenly appeared on the Tianbei, shaking like wind and rain.

At the next moment, the veins directly enveloped the whole Tianbei and made bursts of sounds, which seemed incomparably crisp.

Xiao stared at the veins on the Tianbei. He didn't know these things, but subconsciously told himself that these were words, probably from a previous era.

Tear

Then the Tianbei flew directly, turned into a fine awn and disappeared,

Then an entrance to the cave appeared in front of them.

"This... What's the matter? Why did the monument suddenly move and even expose the entrance?"

"Where did the monument go that day?"

Donghuang qianxuan and sikongming were confused. They thought they would try their best to remove the Tianbei.

Where do you know that as soon as they get close, the Tianbei will automatically move away.

Xiao Naihe didn't speak. He vaguely knew why.

"The four elephant Sutra again."

When he approached just now, the four elephant Sutra suddenly moved, and then the Tianbei flew away.

There is only one possibility that the four elephant Sutra leads the Tianbei, or something in it.

At this time, Xiao could not help being curious and looking forward to what would make the four elephant Sutra so active.

Following Xiao Naihe, Dong Huang qianxuan and Si Kongming became excited and nervous. They stared at the depths and seemed afraid to miss any details.
