Song Family Ancestral Hall.

Qin Yi and the others soon returned here, but Song Yuan and Song Bo had not yet come out.

"What do you want to do?"

Although Qin Ming didn't quite understand where Qin Yi's confidence came from, he didn't care about the Yuan Dao martial artists who were about to arrive, and when he saw that his younger brother was going to wait in front of the ancestral hall at this time, he asked suspiciously.

Qin Yi was silent for a moment and said, "Come out." ”

Before the words fell, Song Yuan and Song Bo walked out of the Song family ancestral hall.

"What's going on?"

Song Yuan saw Qin Yi and the others waiting at the door, and Qin Ming and the others' faces were a little wrong, so he asked worriedly.

Because of the protection of the formation, Song Yuan and Song Bo didn't notice what was happening outside.

"Are there two of these patterns in there?"

Before Qin Ming could speak, Qin Yi looked at Song Yuan and said seriously.

With that, he condensed his true qi, and his fingers danced in the air, drawing a mysterious pattern, which looked like a flower with a five-pointed star.

"Huh?"

Seeing this, Song Yuan couldn't help but be stunned, wondering how Qin Yi could know the pattern on their Song family flag, but he quickly nodded and said, "There are two." ”

"That's right."

When Qin Yi heard this, he knew that his guess was not wrong, so he took out two array stones, handed them to Song Yuan and Song Bo, and said, "Put these two array stones in the center of the pattern and drip your blood." ”

"Okay."

Although Song Yuan didn't know why, it was obvious that something big had happened, so he took the array stone in Qin Yi's hand and turned to leave.

Song Bo hurriedly followed.

"Are you going to use the power of the formation?"

Qin Ming quickly understood something and asked curiously.

"Hmm."

Qin Yi nodded and said, "Originally, I only thought that there were only two formations here, the Phantom Ghost Array and the Phantom Immortal Array, but just now, the Phantom Immortal Array guarding the ancestral hall protected the entire mansion, and I realized that the Phantom Ghost Array was not destroyed by anyone." ”

Speaking of this, he thought about it seriously for a while, shook his head, and said: "No, it shouldn't be said like this, it was indeed destroyed, but that person didn't expect that the entire formation could repair itself, just when the Phantom Immortal Array broke out, the Phantom Ghost Array repaired itself." ”

"And this?"

It was the first time Qin Ming had heard that the formation had the ability to repair itself, but he also knew that he knew very little about the formation.

"Hmm."

Qin Yi smiled slightly and said, "Because this is a five-joint formation, destroy one of them, and once the other formations are triggered, the destroyed formation will repair itself." ”

"Wulian?!"

When Xu Mengjiao heard this, she couldn't help but be taken aback, obviously in terms of formation, among the people present, she was the only one who could keep up with Qin Yi's train of thought.

Qin Yi nodded solemnly and said, "To be honest, I was also taken aback, I didn't expect to see this legendary formation in this place. ”

"Legendary?"

Qin Ming was even more curious.

"The five-joint formation is known as the 'immortal formation'."

Qin Yi explained.

"Indestructible?"

Qin Ming looked incredulous.

"In a sense, it is indeed immortal."

Qin Yi nodded, and said solemnly: "Unless you can destroy the five-union formation at the same time." After a pause, "It's just that the five-joint formation is composed of five formations, and every two formations form a formation within a formation, and every two formations form a formation within a formation." ”

Speaking of this, he became a little excited, and said: "There are too many changes in this, generally speaking, unless it is the person who sets up the formation, it is difficult to find the real formation, and it is difficult to destroy the five-joint formation at the same time."

"Of course, there is also a violent breaking formation, at the same time, destroying the five formations is also the interaction of the five formations, and the power of the five formations is by no means as simple as the addition of the five formations, but a geometric increase.

"It's like the five-link formation that guards the Song family's mansion, although it is a five-level one-stone formation, but its power is comparable to the spirit-level six-stone formation, even if it is the ninefold peak of the Yuan Dao, it can't be destroyed."

"This!"

When Qin Ming heard this, he was taken aback.

Even Xu Mengjiao was taken aback, although he knew the five-league formation, he didn't expect it to be so terrifying.

Qin Yi just smiled, these things were naturally told to him by the little ghost dragon girl when he was cultivating the formation path in the ancient tomb, and he couldn't believe it when he heard it, but after seeing the five-link formation of the Song family's mansion, he realized that he had underestimated this legendary formation.

However, Qin Yi knew that he was able to see through the five-joint formation so quickly, and it was really thanks to the Book of Changes, through his strong deduction ability, that he could know one or two.

Moreover, Qin Yi didn't know why, and always felt that, to a certain extent, the five-link formation had an indescribable connection with the Book of Changes.

"Five elements?"

Qin Yi had such a conjecture.

Because according to legend, there is also an eight-link formation that is more powerful than the five-link formation.

According to the little ghost dragon girl, this eight-group formation method is too terrifying, and anyone who sets up the formation will be punished by heaven.

The little ghost dragon girl has never seen the eight-joint formation.

However, Qin Yi guessed that the eight-alliance formation might be related to gossip, and he hadn't seen it for the time being, so he couldn't confirm such a conjecture.

The five elements are born together, and they are endless, which just shows the immortality of the five-link formation.

More critical ......

Qin Yi did see through this five-link formation through the theory of the five elements and with the help of the "Book of Changes".

Phantom Array, Phantom Immortal Array, Phantom God Array, Phantom Demon Array, Phantom Spirit Array-

Five Illusion Town!

This is the name of this five-league formation, and it is also one of the three five-league formations that Qin Yi knows.

Being able to see it here, Qin Yi was naturally excited, and it was of great benefit to the formation path.

"Buzz!"

Just when Qin Yi was thinking, there was a slight tremor from the ancestral hall of the Song family.

A moment later, Song Yuan and Song Bo walked out of it.

"Brother Qin Yi, what are you going to do next?"

Song Yuan asked suspiciously, also realizing what was going on.

I saw the sky, several figures, stepping into the air, and at a glance, I knew that it was the realm of the Yuan Dao.

"Get in."

After that, Qin Yi walked into the ancestral hall of the Song family.

So, the others followed.

"Huh?"

A figure, in a flash, appeared at the door of the Song family ancestral hall, but he didn't go in, but his brows furrowed tightly.

Even the other Yuan Dao martial artists only stopped at the door of the ancestral hall of the sect in the end, not daring to take a step beyond the thunder pool.

An inexplicable sense of danger haunted them.

They knew that as long as they dared to step into the ancestral hall of the Song family, maybe they would never be able to get out again.

The realm of the Yuan Dao, the law of perception.

They clearly felt that the surroundings were full of terrifying laws, and the ancestral hall of the Song family was a forbidden area for these laws.

Once they step into the restricted area, it is equivalent to detonating the laws of the surrounding area.

Maybe they won't die, but it's worse than dead.

Live forever in a fantasy world.

Both body and soul.

"What should I do?"

"Wait and see."

"That's the only way."

……

All of a sudden, those Yuan Dao martial artists all discussed, looking at their clothes, they should be disciples of the sect, but they are not from the five major sects of Nanlin.

……

Although Qin Yi guessed something, he didn't know that the appearance of the cave mansion had made the major sects of the Four Desolations active.

Obviously, this exploration of the cave is prepared for the ancient tomb of Huanghe Town.

Training!

Without such experience, entering the ancient tomb is only a dead end.

The cave is the abode of the sage, and in a sense, compared to the ancient tomb, the danger level is not so high, and it is easier to obtain opportunities.

Although the danger of the cave is slightly smaller, it is still not accessible to everyone.

As for secret realms, the level of danger varies greatly.

However, these three places, no matter how dangerous they are, are all dreamed of by martial artists.

Qin Yi entered the ancestral hall of the Song family, but stopped.

"What's wrong?"

Seeing this, Song Yuan couldn't help but be stunned, but soon, his eyes widened suddenly, the original ancestral hall disappeared at some point, and what appeared in front of them was a huge iron door.

It seems that it is ten zhang high, and the pitch-black steel reveals a coldness that makes people's hearts palpitate.

"What's going on?"

Song Bo asked in surprise.

"This time is the true face of your Song family ancestral hall."

Qin Yi explained a little and said, "What you saw before was just an illusion. ”

"This ......"

Song Yuan and Song Bo were completely stunned, and they couldn't understand how Qin Yi could know this.

"It's a formation."

Qin Yi smiled slightly and said, "If I'm not mistaken, there should be a treasure trove inside." ”

"Treasure trove?"

Even Qin Ming was taken aback when he heard this, as if Qin Yi knew everything about the Song family.

"Hmm."

Qin Yi nodded and said, "Perhaps, your Song family was once extremely brilliant. ”

As he spoke, he looked at Song Yuan and Song Bo and said, "It's just that there is no eternal family. After a pause, "Back then, maybe the ancestors of your Song family predicted this, so they left this treasure house, but unfortunately, in the inheritance from generation to generation, the clues of this treasure house were lost, and among the descendants, none of them were able to find these clues." ”

Song Yuan and Song Bo were silent, even if Qin Yi didn't say it, they now understood that the ancestors of their Song family must be incomparably brilliant.

Neither brother knew much about the formation, but they could feel the horror of this formation.

Especially if this formation can resist the Yuan Dao martial artists outside, it is enough to say something.

It is estimated that this is the real reason why Qin Yi has no fear.

It's just that......

How could Qin Yi know this formation.

However, neither Song Yuan nor Song Bo planned to ask more.

Not to mention anything else, they knew that Qin Yi was a very good person, and if it were the others, it was estimated that they would have destroyed their brother long ago and swallowed this treasure house alone.

"Senior Brother Long, Senior Sister Long, it's up to you."

Qin Yi suddenly shouted.

Before the words fell, Long Shu and Long Yutao quietly appeared beside Qin Yi.

Without the cultivation of the Yuan Dao realm, it would be impossible to push open this iron gate that was as heavy as a mountain.
