Although it only showed a hint of coercion, Si Kongming caught it very keenly.

He is not the kind of person who has no knowledge. On the contrary, Si Kongming's background is not small, and behind him is an extremely powerful master.

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

However, no matter how powerful the heavenly sages are, they are not as powerful as the gleam of coercion and terror revealed just now.

There is only one possibility for an unfathomable coercion that is deeper than the sages of the heavens-ancient immortals.

"Could it be that Xiao Naihe is an ancient immortal?" When this thought came into being, Si Kongming couldn't help but tremble, and he didn't dare to think about it anymore.

"No, right? He is definitely not the ancient immortal. It is very likely that he is nostalgic for the treasures of the ancient immortal strong, or even what the ancient immortal strong left him."

Si Kongming slowly calmed down, Xiao Naihe's cultivation level could not be faked, and he would definitely not be Guxian.

He estimated that behind Xiao Naihe there should be an ancient immortal-level powerhouse, perhaps even Xiao Naihe's master.

Otherwise, it is impossible to explain that Xiao Nai could kill the Awakened God King in the second stage of Immortality.

The more he thought about it, the more terrifying, Sikongming was both frightened and excited: "I didn't expect that the backer behind him was actually a strong ancient immortal. Let alone the ancient city, even if the entire eastern realm is moved out, it is estimated that there is not much ancient Immortal."

No wonder Xiao Nai is not even afraid of the Yan family or even the Golden Crow family, and only after the strong ancient immortal can he have such confidence.

Xiao Naihe still didn't know the two thoughts that Si Kongming and Donghuang Qianxuan had in their hearts, but it didn't matter if he knew.

He couldn't stop the trace of fairy rhyme that was revealed by the fairy fetus just now. As long as they couldn't see the fairy fetus, they would inevitably think of the strong ancient immortal. Maybe they had other speculations in their hearts.

"Just as I thought, Guxian's Daoyun is the key to unlock the'Southern Sixth Array'." Xiao Nai couldn't help but smile.

He put away the immortal tire and landed on the ground. At this time, Donghuang Qianxuan and Si Kongming looked at Xiao Naihe's expressions slightly.

"The big guy is the big guy, and even the'Southern Sixth Formation' can open." Si Kongming's tone became enthusiastic.

Donghuang Qianxuan is not stupid, she just didn't turn her mind just now, and now she calmed down and immediately guessed something.

Xiao Naihe swept the expressions of the two of them, and didn't say anything. Instead, he said, "Let's go in. After we open the barrier, maybe it will attract the attention of others, faster."

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

Just as the three of them stepped into the depths of the rift, there was a burst of pressure from several places in the ancient city at the same time.

Several old undead suddenly opened their eyes, and their eyes seemed to have insight into thousands of existences and traveled through the ages.

"That formation has been opened? Who is it? Unless the ancient immortal makes a move, it is impossible for anyone in the ancient city to open the enchantment of the Southern Heaven Form Saint."

"No, you have to go and see it."

At this time, several figures came out of the ground and flew directly in the direction of Huang Fenggu.

In the valley of Huangfeng, Xiao Naihe and the three have entered the depths of the rift and entered a small enclosed space.

After entering this small space, it was not as small as Xiao Naihe had imagined.

In the small space, there is another small world, with mountains and mountains across the front, and mountains like Tianzhu upright up into the sky.

But after crossing the river, it was a vast expanse, and thick fog enveloped it, and no one knew what was inside.

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

The "Four Elephant Sutra" in his eyebrow actually reacted.

"What's going on? The "Sixiang Jing" has a reaction? I'm afraid there is something uncomplicated in it, which may have something to do with the Four Elephant Jing."

Xiao Naihe's heart was shaken slightly.

The "Four Elephant Sutra" is not a mortal thing, it is a relic of the era. The nine heavenly objects between the heaven and the earth are the core treasures of the era originating from other eras.

It is definitely not simple to cause a reaction in the "Four Xiang Jing".

"Can we get in?" Donghuang Qianxuan also hesitated when seeing Xiao Naihe hesitating.

Before they knew it, they slowly focused on Xiao Naihe.

Xiao Nai breathed a sigh of relief, suppressing the strange feeling in his heart, and said, "I have already walked here. There is no reason to retreat. Let's go in."

Before speaking, he first entered the mist.

Donghuang Qianxuan and Si Kongming could only follow in, and they were all here. It would be a pity that they did not go in.

In the mist, there are still huge mountains, and the highest peak actually reaches the zenith, which seems to stand on the top of the galaxy finger.

Standing in front of this peak, Donghuang Qianxuan and Si Kongming immediately felt an unspeakable shock in their hearts.

The majestic and majestic power of Jufeng seems to have driven this world, and the natural environment has all manifested the extraordinary work of this world.

"There seems to be a huge monument in front." Si Kongming said suddenly.

Sure enough, there was a sky stele under the giant peak, which seemed to block both ends of the sky and the earth, cutting off the starry sky.

This monument looks very awkward and weird.

Especially when Xiao Naihe approached, this heavenly monument suddenly started to act on its own.

"What a..."

Suddenly, countless veins appeared on the sky stele, and they swayed like wind and rain.

In the next moment, the veins above directly enveloped the entire sky stele, making a burst of sound, which seemed extremely crisp.

Xiao Nai Hesi stared at the veins on the sky stele. He didn't recognize these things, but subconsciously told himself that these were words, most likely words from a certain era.

Tear...

Afterwards, the sky stele flew directly, turning into a fine light and disappearing.

Then the entrance of a cave mansion appeared in front of them.

"This... what's going on? How could that monument suddenly move, even revealing the entrance?"

"Where did the monument go that day?"

Donghuang Qianxuan and Si Kongming were at a loss, they thought they had to do everything possible to remove the monument.

No one knew that as soon as they approached, the monument would automatically move away.

Xiao Naihe didn't speak, he knew why.

"It's the "Sixiang Jing" again."

Just now when he approached, the "Four Elephant Sutra" suddenly moved, and then the sky stele flew away.

There is only one possibility that the "Four Elephant Classics" has drawn the monument or something in it.

At this time, Xiao Naihe couldn't help but feel a little curious and anticipating in his heart. What is it that makes the "Four Elephant Classics" so active.

Following Xiao Naihe, Donghuang Qianxuan and Si Kongming became excited and nervous, staring at the depths, seeming not to dare to miss any details.
