After carefully recalling the matter of ancient Chinese music, Li Nan tried to analyze: "The pentatonic scale is in the order of the fifth degree, starting from the palace sound to the feather sound, in order: Gong-Shang-Jiao-Zheng-Yu......"

Jin Guangxian and the others naturally knew these basic knowledge, so he reminded: "Well, we also know this, but how to crack this formation?" ”

"Don't worry, don't worry." Li Nan continued: "As you said, the formations in the world are inseparable from yin and yang, two yi, five elements and eight trigrams, so these five tones also have something to figure out with the five elements. ”

"According to the Five Elements Doctrine, the palace is the sound of the earth, in the center, corresponding to the four directions and the four times; The horn is the sound of wood, living in the east, and the time sequence is spring; It is the sound of fire, located in the south, and the time sequence is summer; Shang is the golden sound, living in the west, and the time sequence is autumn; The feather is the sound of water, living in the north, and the time sequence is winter. ”

"I see!" As the so-called words woke up the person in the dream, after Li Nan said the connection between the five tones and the five elements, Jin Guangxian and the others suddenly woke up.

Now that the principle of this five-tone array is known, it is not difficult to crack this array, and the two immortals and one soul have studied for several days according to the method of mutual growth and restraint of the five elements, and finally succeeded.

As soon as the five-tone array broke, the iceberg in the distance could no longer move, and everyone came to the bottom of the mountain.

I didn't realize it from a distance, and it wasn't until I stood at the bottom of the mountain that Li Nan and the others knew how high this mountain was.

The outer layer of this mountain is covered by ice and snow, and a few people look up and can't see the mountainside at all, but it is estimated that this mountain should be hundreds of miles in circumference, ten thousand miles high.

There is no need to look for it, a mountain gate made of boulders stands not far away, and three big characters are engraved on the lintel ----Xuanyin Gate!"

After a journey of thousands of miles, they finally found this hidden sect, and several people couldn't help but be happy in their hearts, but when they thought of the history of Xuanyin Sect in the past, they were a little uneasy.

The founder of the Xuanyin Gate is called the Miaoyin Fairy, this immortal is unwilling to participate in the affairs of the Three Realms because of her cold personality, and her reputation is naturally not obvious, but just because she can defeat one of the saints of the year, the second sect leader of the Western Sect, it is enough to prove her strength.

The two saints of the Western Sect practiced in the Western Elysium, and the battle of the gods came to the Central Plains, which was the power of the saints along with the Tongtian Sect Master, Yuan Shi Tianzun, Taishang Laojun, Nuwa Niangniang and others.

During the Great War of the Gods, the Zhun Ti Daoist relied on his own cultivation of the Western Sect One Pulse Exercises, the Seven Treasures Wonderful Tree, the Blessing Divine Pestle and several other top magic weapons across the Three Realms, and no one could stop them.

However, even the great power of saints such as the Zhun Ti Dao people, when they wanted to occupy and gather various sects, they also encountered hard bones, and were directly injured by the master of the Xuanyin Sect, Miaoyin Fairy, and returned to the West to cultivate.

It is said that after that battle, Fairy Miaoyin died of serious injuries, but she was able to defeat the leader of the Western Sect, Zhun Tidaoren, which also proved that her strength could compete with the saints.

Now the few people standing in front of the mountain gate are not in very good condition.

Li Nan only has the Earth Immortal Realm and can only be regarded as an intermediate-level cultivator, while Shen Gongbao has lost his physical body and can't contribute much at all, while the Golden Light Immortal and the Spirit Tooth Immortal have been tortured for thousands of years, and now the realm has plummeted.

Everyone hesitated for a moment, but the Spirit Tooth Immortal took the initiative to say: "A sect like Xuanyin Sect will inevitably have a way to protect it, so let me try it first." ”

At present, among the few people, the realm and strength of the Golden Light Immortal and the Spirit Tooth Immortal are the highest, plus the Spirit Tooth Immortal body is a yellow-toothed giant elephant, and he is born with very strong defensive power, so it is also the most suitable way for him to test it.

Li Nan knew that his strength was low, but seeing that the Spirit Tooth Immortal was willing to take risks, he also quickly took out the magic weapon Sanpin Golden Lotus that he had won from Fuxian.

"This treasure is specifically used for defense, I have crossed out the prohibition above, and you are defenseless, so take this magic weapon to defend yourself."

The Spirit Tooth Fairy was also worried in his heart, so he did not shirk it, and immediately took over this magic weapon.

After testing the effect of the three-grade golden lotus for a while, and feeling that he could be retracted and released freely, the Spirit Tooth Fairy took a deep breath and raised his feet and stepped into the mountain gate of Xuanyin Gate.

"Jingle bells! Jingle ......"

The moment the Spirit Tooth Fairy entered the mountain gate, several loud bells rang immediately.

The bell was just a prelude, followed by the unusually rapid and powerful sound of the lute coming from the top of the towering iceberg in front of everyone, but the distance did not make any difference, and everyone felt as if someone was playing in front of them.

The others are just that, they don't understand the rhythm of music, so they can't hear anything, but Li Nan, who has some research on music, secretly says that it is not good.

This pipa song is high and agitated, majestic, with the faint sound of dragon roar and phoenix roar, and it is full of strong killing intent just before a prelude.

As this pipa song played faster and faster, the Spirit Tooth Fairy, who walked into the mountain gate, also found that an incredible phenomenon appeared in front of him.

A large number of spirit beasts that resemble dragons and non-dragons, phoenixes and phoenixes, and unicorns and non-unicorns are divided into three directions, raising their claws and raising their heads, roaring at the sky, exuding an irresistible majesty.

Although it was only separated by a mountain gate, Li Nan and the others outside could not see these scenes, they could only see that the Spirit Tooth Fairy immediately made a vigilant posture after the pipa song sounded, and the whole person's body was trembling unconsciously.

"Brother Lingfang, what's wrong?" Li Nan asked.

Jin Guangxian, who is also an ancient spirit beast, saw the appearance of the Spirit Tooth Immortal at this moment, and he explained: "We have intersected so far, but I have never seen him become like this, but it seems that he has met a natural enemy nemesis, so his body will have an instinctive fear reaction. ”

Speaking of this, Jin Guangxian said with a puzzled face: "But Brother Lingfang himself is a xenomorph yellow-tusked giant elephant, how could any creature in this world scare him into such a look?" ”

Under the gaze of Li Nan and the others, the Spirit Tooth Immortal sacrificed the three-grade golden lotus talisman a few seconds later, but this magic weapon specially used for defense did not last long at all, and it was broken by some powerful force.

After the Spirit Tooth Immortal was defeated by the three-rank golden lotus magic weapon, he also realized that something was wrong and wanted to flee backwards, but he didn't seem to be able to see the mountain gate that was close at hand, and he was immediately hit.

Seeing that the Spirit Tooth Fairy was beaten and vomited blood, Jin Guangxian couldn't bear it anymore and rushed directly into the mountain gate.

Jin Guangxian's experience was the same as that of the Spirit Tooth Fairy, he also sacrificed the male and female Wu Hook Sword magic weapons, but he didn't last long, the magic weapon was knocked away, and he could only barely protect the injured Spirit Tooth Fairy.

The two strongest helpers were in distress, and Li Nan was also anxious at this time.

Today's situation is obvious, Xuanyin Gate has some kind of mountain protection formation related to music rhythm, as long as you enter the mountain gate, this formation will be triggered.

It can be seen that this formation is very powerful, so much so that powerhouses of the level of the Golden Light Immortal and the Spirit Tooth Immortal can't last long with a magic weapon to protect their bodies.

Go in to save people or stay in danger? This is a matter of life and death, so Li Nan couldn't help but hesitate.

Set a small goal first, such as remembering in 1 second: book guest residence
