Sun Fengzhao decided to rest for a while before opening the hatching hoods. Glancing at this central area, and finding no ancient treasures such as "keys", Sun Fengzhao sat down on a stone pier in the middle, and suddenly felt relieved.

"Hmm, there are also carved runes on this stone pier!" Sun Fengzhao sat on the stone pier, and it was immediately very uncomfortable to be left with the different shades of dents on it.

After a moment of shock, Sun Fengzhao hurriedly moved his butt away and looked down at the stone pier. After a while, Sun Fengzhao, who saw a little bit of the doorway, muttered in surprise: "These runes seem to have some traces of the formations I have learned, it seems that these ancient monks are really not good at the study of formations, but they know how to explore, and in the process of continuous study, they have begun to master some of the prototype ....... of the formation."

This pattern carved with the prototype of the formation is not complicated, you must know that the ancient immortal cultivators, since they are still just beginning to explore the prototype of the formation, it must not be too complicated. Sun Fengzhao believed that the formation could be as complex as it is today, and it must have developed to the present day on the basis of inheriting these rudimentary formations of the ancient monks.

At this moment, Sun Fengzhao was immediately overjoyed, although he was not very good at tinkering with such advanced and complex things as formations, but Sun Fengzhao had learned some basic knowledge from Lu Wantian and Chu Yunfei.

At this time, it was just right to apply what he had learned, and Sun Fengzhao ran around this circle of stone piers, constantly groping back and forth on those stone dun, and even pushed a few stone duns to move their positions in the end.

Sun Fengzhao moved these stone piers before he was determined, and these stone piers seemed to be connected. But in reality, these stone piers are movable. After a push, the whole ground will move like a building block.

Sun Fengzhao didn't use any mana, and after pushing the stone piers for the last time, his eyes widened, watching the ground go back and forth busy activities, and finally changed the position of those stone piers many times.

Suddenly, Sun Fengzhao heard a slight shaking on the ground under his feet, and then heard the sound of the clattering stone slabs turning, with this circle as the center, the stone slabs on the ground suddenly moved automatically, one by one, some folded, some moved, and the stone piers above also slowly moved, after a few circles along some specific tracks.

The glowing stones above their heads quickly dimmed in brightness, and in the midst of this circular formation, suddenly a crack opened in the ground! More and more floors retreated to both sides, and the stone steps below also floated little by little, like a tide, retracting back layer by layer!

In the end, the ground in this circle completely disappeared! A huge underground entrance several zhang wide appeared in front of Sun Fengzhao's eyes!

Then a staircase several feet wide appeared in front of Sun Fengzhao, dragging it all the way down, and it was pitch black below, and I didn't know where it leads......

"It turns out that this formation doesn't necessarily need an immortal cultivator to control it, and the formation created by the ancient immortal cultivators can even be controlled ?......by ordinary mortals."

Why did the Ancient Immortal Cultivators start to use this kind of magic circle that even mortals could open as they went deeper into the entrance of the core area?

Sun Fengzhao came to such a conclusion because he lacked keen observation. He didn't notice the fact that when this formation was opened without using any mana, the hedrons embedded in the ceilings of the caves suddenly dimmed. This formation did imply the elements of the mechanism, but when Sun Fengzhao opened it, it was still the spar on the top of the cave that supplied the mana to finally activate the mechanism. It's just that the alternative approach of the ancient monks can't be detected with Sun Feng's current cultivation and experience.

It is wrong for this ancient formation to be understood by Sun Fengzhao as a pure mechanism, and it should be called a "formation mechanism", which is more appropriate.

Regarding Sun Fengzhao's own doubts, Sun Fengzhao still can't answer them. But suddenly, Sun Fengzhao's mind flashed, and a vague thought seemed to flash: Could it be that the lower the region, the ancient people who lived were not immortal cultivators, but mortals?

Sun Fengzhao suddenly remembered something strangely, after killing the third-level double-headed carrion ape snake, the bones of the Long monk in the remains passage behind the hall seemed to be a Dharma Body Double Cultivator, and he also said something in his last words, "The last trial production was finally successful" and something like that. Could it be that the Ancient Immortal Cultivators were already studying how to enable mortals to have the Immortal Cultivation Spiritual Root?

Isn't it true that he is a mortal who has no spiritual roots, and has become a person with an immortal cultivator system through artificial cultivation of spiritual roots?

If Lu Wantian and the others were able to do it now, why didn't the ancient monks think of it, and they had already succeeded?

But soon Sun Fengzhao thought that this set of secret techniques by Lu Wantian and the others was obtained from the classics left by the great rebel of Song Gaozong, Zang Qingyun, and should not be from the ancient inheritance.

So where did the Tibetan blue cloud come from or pass it on?

Sun Fengzhao's mind was a little messed up all of a sudden, so he automatically stopped thinking about it for the time being. But a very bad connection, many connections made Sun Fengzhao find that everything here seemed to have a continuous connection with the rise and fall of Song Gaozong, Tibetan Qingyun.

"Anyway, I can't get out for a while anyway, so it's better to go down and take a look......." Half helpless, half curious, Sun Fengzhao temporarily gave up the idea of using a large amount of spirit beast blood to open the teleportation array and return to the ground, and decided to explore what amazing things were under this third layer.

It's still a huge underground space with an unfathomable circle. But when Sun Fengzhao took a look, he found that the prohibition in the underground space below was a little different from the previous one, and the red light curtain around it still existed, but there was an extra layer of thick gray fog, which could not see through the inside.

With his hands behind his back, he slowly walked towards the red light curtain. After Sun Fengzhao entered the entrance of this floor, the entrance closed and closed by itself as usual.

Sun Fengzhao was not in a hurry this time, and then he quickly came to the front of the ban, and circled around it three or four times before stopping.

As soon as he raised his hand, a small silver sword about an inch long shot out from Sun Fengzhao's storage bag. Sun Fengzhao was now more and more familiar with the use of this ancient treasure, and he could already use his divine sense to open the storage box in the storage bag and directly take out the ancient treasure inside.

The Gengyin Dragon-shaped Sword circled a few times above Sun Fengzhao's head. As soon as Sun Fengzhao's divine sense moved, it suddenly turned into a silver ray and pierced straight into the red light mask.

There was a soft "bang", and a bright silver light flashed where the light mask was pierced by the small sword, and a gap appeared. But before Sun Fengzhao could take any action, a powerful force suddenly came from inside, and the sound of the Gengyin dragon-shaped sword "poof" was actually bounced out. The Gengyin Dragon-shaped Sword, which was the key to this kind of prohibition, actually bounced back directly, and it didn't work as well as it did to break the prohibition before.

As soon as the gray mist filled the crack, the crack closed in a red light, and quickly returned to its original state.

Sun Fengzhao was surprised at first, and then his face became gloomy. He touched his chin and stared back at the red light curtain and the gray mist.

It didn't take long for Sun Fengzhao's face to soften and smile slightly.

Seeing this scene, Sun Fengzhao was not angry but happy. Because the more this is the case, the more it shows that the things inside this forbidden light curtain are more and more precious.

Sun Fengzhao slapped his storage bag again with excitement on his face, took out the gold brick in a row, and after a long roar on Sun Fengzhao's head with the Gengyin dragon-shaped sword, he synthesized a stream of gold and silver light.

"Chop!" Sun Fengzhao roared.

The two ancient treasures that were merged together, under Sun Fengzhao's trick to split Huashan, the combined gold and silver light and shadow were in full bloom, and they were unceremoniously split at the forbidden light curtain.

With a "boom", the moment when the cover wall was forbidden to touch, a gap several feet long was broken open.

I saw that the red and gray forbidden, as if cut into two pillars of light. Suddenly, under a red and gray aura, the underground space of the entire layer suddenly darkened. Then the sound of the sky falling apart erupted all around. The forbidden space in front of Sun Fengzhao was even more trembling, and there was a squeaky squeak. It makes people feel uncomfortable when they hear the sore teeth.

When the red and gray light on the forbidden light curtain rose unwillingly, the gap that had been broken was actually shrunk again in a burst of distortion, but the speed of recovery was three points fuller than before.

When Sun Fengzhao saw this situation, he showed a hint of joy. But he didn't dare to slack off, accepted the two ancient treasures, and immediately turned into an orange glow, and flew into the forbidden inner wall from the gap that had not yet closed. It was at this time that the re-bridged prohibition came together.

At this time, Sun Fengzhao, who was in the orange light, appeared in the forbidden light curtain. Without stopping, after entering the prohibition of this layer, Sun Fengzhao, who immediately released his divine sense, immediately discovered that the aura in this place was so dense that it was almost to the level of a person.

Sun Fengzhao has been in several places with dense aura in Songgao Sect, but the degree of aura density here can be described as very different.

After feeling the aura of the people here, Sun Fengzhao immediately found that there seemed to be some spiritual grasses and elixirs planted around here, and there was also a complete stone pavilion and a half-section corridor. Under the forbidden red of the four walls of the space on this floor and the high sky, there is a gray patch, and there is nothing else.

"This place actually seems to be an incomplete elixir garden!" Sun Fengzhao was standing at this time in a window-like platform opened on the fog wall, and there was a long bridge about dozens of zhang long in front of him, floating in the air out of thin air.
