Thinking of this, Ma Feifei entered his mind and asked the system, but this time the system did not give an answer, which means that the question of the fragments of the book of heaven needs to be solved by Ma Feifei himself after completing the task of holding the book girl and getting a reward.

However, although the doubts have not been solved, at least one thing is certain that there should be ninety-nine Heavenly Book Fragments hidden in the Nine Mountains, and to be precise, the spirit beasts in the Nine Peaks should have Heavenly Book Fragments hidden in their bodies.

Ma Feifei wanted to collect these Heavenly Book Fragments to definitely find these spirit beasts, but how big the Nine Mountains were, there were countless spirit beasts in it, God knows which spirit beasts these ninety-nine spirit crystals were hidden on, and more importantly, what if the spirit beasts containing the Heavenly Book Fragments were hunted and killed by cultivators? What if they were picked up by other cultivators?

These are all unknown issues.

"It really hurts my head. Ma Feifei looked at the fragment of the Book of Heaven in his hand and sighed. He originally entered Jiuzhong Mountain to find Yu Qingyang, but Yu Qingyang didn't find it, but instead a fragment of the Book of Heaven came out, and Ma Feifei, who was in a mess, felt that his brain was completely insufficient.

"Let's go. Ma Feifei glanced at Brother Gongzi, who was lying on the ground and had not yet recovered his strength, shook his head and walked towards the ninth mountain.

As for the boy lying on the ground, they didn't want to meddle in their affairs, whether they could survive in this nine-fold mountain or not depends on their creation.

"Ahem!" Brother Gongzi coughed up a mouthful of blood, lay in the arms of the sword-wielding woman, looked at the back of Ma Feifei and his party in the distance, and asked in a weak tone: "Spring silkworm, do you recognize them?"

The spring silkworm was using spiritual power to repair the broken meridians in Brother Gongzi's body, and when he heard this, he glanced at Ma Feifei and the others who were leaving, frowned slightly, and replied: "I don't know, but a few days ago, I heard that there is a Tongtian ape from the depths of the 100,000 mountains in the territory of Dachu, which is said to have been accepted as a gatekeeper by the magical bookstore, and I don't know if it is the one just now."

"Magical bookstore?" Childe muttered to himself, lost in thought.

......

In the Nine Mountains, Ma Feifei and his party continued to run towards the Ninth Mountain, the deeper they went, the more Ma Feifei could feel the horror of the Nine Mountains, all kinds of strange-looking spirit beasts that couldn't be named looked at Ma Feifei in the dark with big eyes.

Some are only the size of a palm, hidden on the leaves, some are hundreds of meters large, like a small mountain, crawling on the ground, some swim in the water, hidden in the trees, fly in the sky, all strange, but all of them are above the level of spirit beasts above the eighth order.

Here, Ma Feifei deeply felt the horror of the Nine Mountains, there were as many eighth-order spirit beasts as dogs, and ninth-order spirit beasts were everywhere.

This is difficult to resist even if an ordinary Spirit Saint comes in, let alone a cultivator below the Spirit Saint realm.

That is, the aura of Ma Feifei and his party is too strong, especially Bajiu and Tongtian Ape, who are divine beasts themselves, they are no different from their own homes when they walk in Jiuzhong Mountain, and those spirit beasts take the initiative to avoid them after seeing them, let alone come forward to disturb them.

Soon, the group came to the destination of the trip, which is the center of the Nine Mountains, the Ninth Mountain.

At this time, it was already the last quarter moon hanging in the sky, and it was obvious that they had spent a lot of time from the periphery to the ninth mountain.

"Is this the Ninth Mountain? It feels so desolate. Ma Feifei looked at the bare wasteland in front of him and asked curiously.

Although it was late at night, for Ma Feifei, their sight would not be affected in the slightest, in Ma Feifei's sight, the whole world was a desolate wasteland, and there was no life in sight, not even a single tree or grass.

There is no other color except fine gravel, which is sand.

"It's just the edge of the ninth mountain, and it's different when you go inside, there are a lot of fruit trees, swamps, rivers, it's beautiful. Bajiu, who was born in the ninth mountain, said, but his face did not show the joy of going home, and it was clear that he did not like to come back here.

"By the way, inside, there is also an ice crystal palace, I heard from my mother that it was where the frost dragon used to live, but there is a formation outside the palace, and we can't get in. Ba Jiu seemed to remember something, and took this sentence.

When Ma Feifei heard this, his eyes lit up, isn't this ice crystal palace where Yu Qingyang lives!

"Lead the way, go straight to the Ice Crystal Palace. Ma Feifei said excitedly.

"Good. Ba Jiu was very familiar with the Ninth Mountain, and immediately walked forward, followed by Ma Feifei and the others.

After another period of time, Ma Feifei's eyes were finally not desolate, but instead there was a large area of bushes, swamps, and the occasional murmuring of water in his ears, as Ba Jiu said.

"Further on is where Mother lives, and now Mother is supposed to be in retreat, and we can go around a little bit, avoiding Mother's perception, and after this bush we will reach the Ice Crystal Palace. Bajiu said, pointing to the bushes in front of him.

Ma Feifei nodded, and chose to follow Bajiu's advice and take a detour, the purpose of his trip was not to find the divine beast to fight, but to find Long Mei, it was naturally better to be able to reduce trouble.

Fortunately, this bush is not very big, Ba Jiu took Ma Feifei and they went around for about half an hour, and finally bypassed the bushes, and then ran forward for about ten minutes, and a huge ice crystal palace came into view of Ma Feifei's eyes.

Ma Feifei was dumbfounded at the first sight of this palace, is this fucking called the Ice Crystal Palace?

The light that flashes with buling buling is really not a spirit crystal?

A palace carved out of spirit crystals!

It simply subverted Ma Feifei's worldview.

"I always thought that Yu Qingyang was just rich, but I didn't expect to be so rich!" Ma Feifei looked at the palace about the size of a football field and sighed.

This palace Ma Feifei visually estimated that if it was dismantled and cut into spirit crystals, it would be at least 500 million starting points, which means that the place where Yu Qingyang lived was luxuriously worth more than 5 billion spirit crystals.

What is this concept? I don't have a concept anymore, because no one has ever done that.

"It is said that ten dragons are nine rich, and one is rich, Qingyang, you belong to the dragon that gets rich, right?"

Not to mention Ma Feifei, even Changkong, who has lived for more than a hundred years, was shocked to see this scene, and he didn't know what to say, in his more than 100 years of time, let alone own, he had never seen so many spirit crystals.

He had seen the Spirit Crystal Mine, and the high-grade Spirit Crystal Vein Mine produced only about 100 million spirit crystals a year, that number was an astronomical number for the sky, not to mention the palace in front of him that was all carved from spirit crystals, he really couldn't imagine this kind of operation.

As for Bajiu and Tongtian Ape, they didn't react, they didn't rely on spirit crystals to cultivate, so they didn't have any concept of spirit crystals.

"There is a formation on the periphery of the Ice Crystal Palace that we can't see, and the only one who can enter and exit at will is the owner of the Ice Crystal Palace. Ba Jiu said with palpitations.

"So powerful?" Ma Feifei looked around the Ice Crystal Palace suspiciously, and he didn't find the existence of a formation when it was empty!

"Teacher, go and have a look. "Changkong is a ninth-order formation master, and he must be the most proficient in formations.

"Okay, stay safe. Ma Feifei admonished.

Changkong nodded and walked slowly towards the Ice Crystal Palace.
