At this moment, what appeared before Nanmen Guo'er's eyes was a huge house. Even though it was a little dilapidated, one could still see its majesty and grandeur through the structure and the corners of the house.

"What is this?" Nanmen Guo'er asked in her heart.

Hearing this, the rune froze and did not move for a moment. It seemed as if it was unwilling to answer.

Seeing Nanmen Guo'er sneer, with a thought, the red pattern on the Runes immediately tightened, causing the Runes to suddenly tremble, the golden light on the Runes also dimmed.

"Haven't we already reached an agreement? You have to cooperate. " Nanmen Guo'er coldly said in his heart, "If you don't cooperate, why would I keep you here? As a remnant soul that has lived for thousands of years, why don't you understand this principle? Furthermore, you said you would guide me. "

Hearing this, the rune flickered as if it was angrily protesting. However, as the red lines shrunk, it could only wilt in the end. After a pause, the rune flashed and sent out a slight fluctuation.

After hearing that, Nanmen Guo'er's eyes immediately opened wide, and said with extreme shock. One of the twelve formation cores? "

It was actually … Twelve Formation Apertures?

Nanmen Guo'er raised her head and looked into the sky in shock, then looked around at the space, and said in disbelief: "Could it be that this is not just a gigantic independent space, but a formation of this size?"

Having revealed the secret of the Formation Aperture, the rune once again flickered as if it was asking for something.

Hearing that, Nanmen Guo'er's state of mind relaxed, the red runes tightly wrapped around her body, at the moment, she could no longer be bothered with the Runes!

Looking at this space, the shock in Nanmen Guo'er's eyes was even more intense than when she found out that the Kun Peng's skeleton was underneath this ruin!

She had studied formations before and wasn't very proficient at it, but she knew a lot. Normally, this array had only one core, and it didn't have a primary or secondary position. Of course, this was only for normal formations.

For some unusually large or special arrays, a single Formation Aperture was far from enough. Aside from a main Formation Aperture, there would be at least one secondary Array Aperture. This kind of array formation was called a multi-layered array formation, and it had many changes and was extremely profound.

Heavenly Sound Sect's great protective formation, the Nine Dragons Sky Slaughtering Formation, was a multiple layered formation, and it was even an extremely rare five layered formation!

The Nine Dragons Sky Slaughtering Formation was made up of a main eye and five secondary eye. The Heavenly Sound Sect had been established for thousands of years, and it had rarely been invaded by any enemy sects. This was mainly because of the Nine Dragons Sky Slaughtering Formation, and so far, no one had been able to attack it!

According to Nanmen Guo'er's knowledge, in the entire Southern Continent, the highest level of formation was the Heavenly Sound Sect's Nine Dragons Sky Slaughtering Formation, followed by the Baijin Pavilion's three layers of formation, Dazzling Hundred Flowers!

Whether it was Dazzling Hundred Blossom or the Nine Dragons Sky Slaughtering Formation, they were all considered Purple Rank formations, and were ranked high in the collection of formations within the entire Profound Spirit Continent!

Of all the array formations she had studied, the highest was this Nine Dragons Sky Slaughtering Formation. But she hadn't expected that there would be a twelve layer array formation in front of her!

This caused her to be extremely shocked!

This was because she clearly remembered that the array formation in the collection of array formations only contained nine layers of array formations! Furthermore, according to her knowledge, the ninth layer of the formation was already the strongest formation that could exist!

Twelve layers?

Who would have thought that a twelve layer formation would actually appear in front of her!

In her knowledge, she had never heard of there being 12 layers of formations in this world! Was this the work of that Reverend Subhuti?

Not only did she create a space of her own, but she also used a twelve-layered formation that she had never heard of before! This was simply unable to calm her heart down. Was this power that surpassed the Purple Rank?

When the Southern Gate's son saw the house in front of him, he immediately became shocked. Such a heaven-defying formation was right in front of him, how could he just let it go like that?!

"Let's go down and take a look." Nanmen Guo'er said with a rare excitement in her voice.

Sensing Nanmen Guo'er's feelings, the Xiao Yin also roared and rushed to the front of the house in a flash.

Nanmen Guo'er immediately walked down to take a closer look. The building was dilapidated after a thousand years and its structure had turned gray, it looked like with a light touch, the grand and majestic building would instantly collapse.

Nanmen Guo'er looked carefully at the house, then looked at the people who retreated to watch because of her arrival. She lowered her head and smiled, then extended her hand to push open the door.

"Miss, be careful!"

Just as Nanmen Guo'er's fingertips were about to reach the door, a man's voice suddenly stopped her anxiously.

Nanmen Guo'er turned her head to look and saw a young and delicate looking boy frowning at her.

Seeing Nanmen Guo'er looking at her, the young lad's face reddened, and he scratched his head and laughed: "Be careful Miss, there's a formation protecting this room, it's impossible to enter without unlocking the formation."

Hearing that, Nanmen Guo'er laughed, and then said slowly: "Thank you for your reminder."

After saying that, Nanmen Guo'er turned around, and once again extended her hand out to open the door, her movements was exactly the same as before, without any change.

"Ah, young lady!" The boy became anxious and was about to reach out his hand to stop it, but he was stopped by the Xiao Yin's tail.

"I naturally know that this place is protected by a formation. Otherwise, how could you just obediently stand here?" Nanmen Guo'er slowly turned her head and said. This house was one of the twelve Formation Apertures, there was no need to talk about its importance. Naturally, he had to have a small formation protecting this pair of Formation Apertures.

Even the five secondary formation cores within the Heavenly Sound Sect were protected by other single layer formations.

Hearing that, the young man was startled. Before he could even react, he saw Nanmen Guo'er's hands continue to move and with a tap of his finger, the door opened with a creak.

Everyone was startled, and looked at Nanmen Guo'er with surprise and puzzlement, but right after, their faces were filled with excitement and fire! Even though this house looked dilapidated, since there was a formation protecting it, there must be something good inside! This was the reason why the onlookers did not leave!

And now that the door was opened, what were they waiting for? Charge in!

All the onlookers immediately started to get restless.

Nanmen Guo'er glanced at the people's expressions from the corner of her eyes, laughed lightly, then walked in, and said: "Xiao Yin, watch the door."
