Although there was only a hint of coercion, Sikong Ming caught it extremely keenly.
He is not the kind of person without knowledge. On the contrary, Sikong Ming has a great background and has an extremely powerful master behind him.
He has even seen the sages in the world more than once, and he has even seen the scenes where the sages in the world take action.
However, no matter how powerful the heavenly sages are, they are not as terrifying as the ray of coercion they just revealed.
There is only one possibility for unfathomable pressure than the sages in the world - ancient immortals.
"Could it be that Xiao Naihe is an ancient immortal?" When this idea came to his mind, Sikong Ming couldn't help but tremble and didn't dare to think about it anymore.
"No, no, he is definitely not an ancient immortal. It is very likely that he has treasures given by the ancient immortals, or even something left by the ancient immortals on him."
Sikong Ming slowly calmed down. Xiao Naihe's cultivation level cannot be faked, and he will definitely not be as good as the Ancient Immortal.
He estimated that there should be an ancient immortal level expert behind Xiao Naihe, and he might even be Xiao Naihe's master.
Otherwise, it cannot be explained that Xiao Naihe was able to instantly kill the Awakening God King when he was in the second stage of immortality.
The more he thought about it, the scarier it became. Si Kongming was frightened and excited at the same time: "I didn't expect that the backer behind him was actually a powerful ancient immortal. Let alone the ancient immortal city, even if the entire Eastern Realm were moved out, there probably wouldn't be many ancient immortals. Immortal."
No wonder Xiao Naihe is not afraid of even the Yan family or even the Golden Crow family. Only the powerful ancient immortals have such confidence.
Xiao Naihe still doesn't know the two thoughts that arise in the hearts of Sikong Ming and Donghuang Qianxuan, but it doesn't matter even if he knows.
He couldn't stop the fairy charm from the fairy fetus just now. As long as they couldn't see the fairy fetus, they would definitely think of the powerful ancient immortal, and they might already have other speculations in their hearts.
"Just as I thought, the ancient immortal's Taoist rhyme is the key to unlocking the 'Southern Six Formations'." Xiao Naihe couldn't help but smile.
He put away the fairy fetus and landed on the ground. At this time, the expressions of Donghuang Qianxuan and Sikong Ming looking at Xiao Naihe changed somewhat.
"The boss is the boss. He can even open the 'Southern Sixth Formation'." Sikong Ming's tone became enthusiastic.
Donghuang Qianxuan is not stupid either. She just didn't change her mind just now, but now she calmed down and immediately guessed something.
Xiao Naihe glanced at the two people's expressions and said nothing. Instead, he said: "Let's go in. After we open the barrier, we might attract others' attention, so hurry up."
Sure enough, Xiao Naihe's worry was not unreasonable.
Just as the three of them stepped into the depths of the rift, several places in the Immortal Ancient City suddenly issued a burst of pressure at the same time.
Several old immortals suddenly opened their eyes, and their eyes seemed to have penetrated thousands of existences and traveled through the ages.
"That formation was opened? Who is it? Unless the Ancient Immortal takes action, it is impossible for anyone in the Ancient Immortal City to open the barrier of the Nantian Formation Saint."
"No, I have to go and have a look."
At this time, several figures came out of the ground and flew directly in the direction of Huangfeng Valley.
In Huangfeng Valley, Xiao Naihe and the others had entered the depths of the crack and entered the small enclosed space.
After entering this small space, it was not as small as Xiao Naihe imagined. On the contrary, it was a whole other world.
There is actually another small world in the small space, with mountains stretching across the front, and peaks like pillars rising up into the sky.
But after crossing the river, there was a vast expanse, shrouded in thick fog, and no one knew what was inside.
But when Xiao Naihe's eyes were fixed in the distance, he felt a strange feeling.
The "Four Symbols Sutra" in his eyebrows actually responded.
"What's going on? Has the "Four Symbols Sutra" responded? I'm afraid there are some extraordinary existences in it, and it may have something to do with the Four Symbols Sutra."
Xiao Naihe was slightly shocked.
The "Four Symbols Classic" is not a mortal thing, it is a relic of the era. The nine heavenly books and nine heavenly objects between heaven and earth are all the core treasures of the era originating from other eras.
It is definitely not simple to cause the reaction of "Four Symbols Sutra".
"Can we get in?" Seeing Xiao Naihe's hesitation, Donghuang Qianxuan also hesitated.
Unknowingly, they slowly took Xiao Naihe as the core.
Xiao Naihe took a breath, suppressed the strange feeling in his heart, and said: "We have already come here, there is no reason to retreat, let's go in."
As he spoke, he entered the fog first.
Donghuang Qianxuan and Sikong Ming could only follow them in. They were already here. It would be a pity for them not to go in.
In the mist, there are still huge mountains. The tallest peak reaches directly to the zenith, as if standing on the top of the Galaxy Finger.
Donghuang Qianxuan and Sikong Ming stood in front of this peak, and they immediately felt an unspeakable shock in their hearts.
The majestic power of the giant peak seems to drive this world, and the natural environment reflects the uncanny craftsmanship of this world.
"There seems to be a huge monument in front of us." Si Kongming suddenly said.
Sure enough, there was a sky monument under the giant peak, which seemed to block both ends of the sky and the earth, cutting off the starry sky.
This heavenly monument looks very awkward and strange.
Especially when Xiao Naihe approached, the sky monument suddenly started to move on its own.
"What?"
Countless veins suddenly appeared on the sky stele, shaking like wind and rain.
The next moment, the veins on it directly covered the entire sky monument, making bursts of sounds, which seemed extremely crisp.
Xiao Naihe stared at the veins on the sky monument. He didn't recognize these things, but his subconscious told himself that these were words, most likely words from a previous era.
Tear…
Then, the sky monument flew up directly and turned into a ray of light and disappeared.
Then the entrance to a cave appeared in front of them.
"This... what is going on? Why did the sky monument suddenly move and even reveal the entrance?"
"Where did that monument go?"
Donghuang Qianxuan and Sikong Ming were confused. They thought they would try their best to remove the monument.
Little did they know that as soon as they approached, the monument would automatically move away.
Xiao Naihe said nothing, and he vaguely knew why.
"It's the Sutra of Four Symbols again."
When he was approaching just now, the "Four Symbols Sutra" suddenly moved, and then the heavenly stele also flew away.
There is only one possibility: the "Four Symbols Sutra" pulled the Heavenly Stele, or something inside.
At this time, Xiao Naihe couldn't help but feel a little curious and expectant. What on earth could make the "Four Symbols Sutra" so proactive
Following Xiao Naihe, Donghuang Qianxuan and Sikong Ming became excited and nervous, staring deeply into the depths, as if they did not dare to miss any details.
