The door of the stone gate was tightly closed, and when Xiao Feng's divine sense touched this stone gate, he found that there seemed to be a strong aura in the stone gate.

This is a little strange, there is no spiritual vein in this scalper mountain, how can there be spiritual energy.

For a cultivator, aura is the supreme treasure, and Xiao Feng is naturally a little excited.

Now that he was in the Demon Nest, Xiao Feng naturally had no scruples, and as soon as he stomped on the ground, the person leaped up and jumped towards this obviously different stone gate.

Xiao Feng just hesitated for a moment, then stepped forward to push open the stone door, and with a "boom", the stone door was pushed open by him, and everything inside was under Xiao Feng's eyes.

The stone chamber is about 30 square meters, and there are seventeen pitch-black flags in it, and in the center of the flags is a purple spar the size of a basin.

When Xiao Feng saw this purple spar, his expression immediately changed drastically.

This purple spar looked like a purple spirit crystal with a magnifying board, but Xiao Feng knew that the purple spirit crystal could not be so big.

And in his understanding, such a large piece of purple spirit crystal, there is only one thing similar to it.

Spirit Mother Crystal, according to legend, Spirit Mother Crystal is the source of heaven and earth aura, a piece of Spirit Mother Crystal is buried in the ground, and it will not take many years to cultivate a spirit vein or even a purple spirit crystal vein.

The spirit mother crystal can be described as priceless, but the number of spirit mother crystals is very small, and many purple spirit crystal veins cannot produce spirit mother crystals.

However, Xiao Feng was also skeptical about whether this piece was a spirit mother crystal, mainly because it was too small, and the spirit mother crystal was very large, according to the spirit mother crystal mentioned in the classics that Xiao Feng saw, it should be more than ten times larger than this one, or even larger.

"Is it just a small piece, no matter what, such a treasure must not be missed. Xiao Fengrusi thought, but he didn't step forward, but looked at the small flags planted around him.

These small flags were obviously planted on the ground in a special direction, and they were not planted at random.

Xiao Feng looked at the small banners, his face was a little cloudy, these small banners were either embroidered with strange runes, or embroidered with words such as order and disease, which definitely had its special use.

"Could it be that this is the formation flag of the formation, and this is the hub of the formation. Xiao Feng thought with some uncertainty.

If these small flags are the hub of the formation, then there is a piece of spirit mother crystal here that is somewhat past the past.

The Great Array needs to be driven by Aura, and it is obvious that the Spirit Mother Crystal is the best source of Aura.

Xiao Feng only hesitated for a moment, and immediately took out a gourd, which was the object of the demon cultivator he had killed before.

Opening the lid of the gourd, Xiao Feng's consciousness moved, and a big hand suddenly appeared, grabbing the spirit mother crystal in the array.

However, at this moment, a thick black qi suddenly burst out from the banner and crashed into the big hand.

With a "bang", the big hand was shaken away, and the black gas also dissipated.

Seeing this, Xiao Feng's face sank, and he bumped into the Spirit Mother Crystal, how could he give up.

"If you stop me from taking the treasure, don't blame me for being ruthless. Xiao Feng snorted coldly, raised his hand and slapped it on the storage bag, and the double claw hook was taken out by him. Grabbed it directly towards the small flag.

At the same time, his mind moved, and his big black hand grabbed the spirit mother crystal again.

Sure enough, a black mist erupted from the top of the array banner again, impacting on the claws, shaking the claws away. But the big black hand fished out the spirit mother crystal in his hand and grabbed the formation.

The light on the small banner dimmed instantly, and the ground seemed to have an earthquake, and it began to tremble violently.

Xiao Feng gritted his teeth, rushed to the stone room, rolled up a dozen small flags into the storage bag, and then put away his things and fled towards the tunnel.

Not only did he want the Spirit Mother Crystal, but Xiao Feng also thought about the small array flag.

He had always wanted to have a set of formations, and now that the formations were in front of him, Xiao Feng was willing to miss them.

What he didn't know was that because of his mistake, the young master of the Heavenly Demon Valley had a grudge against him from then on.

Of course, at present, the young master does not know who destroyed the formation and ruined his plan.

The young master of the Heavenly Demon Valley, who is famous and flies at night, he has tried his best to get Yu Jin.

This has to start from two years ago, two years ago, the Heavenly Demon Valley came to the Ten Thousand Saints Immortal Palace to worship, and that time it was the young master of the Heavenly Demon Valley who came to Han Yefei.

On the way back, the cold night flew past Wanxian Island and stopped here, but he didn't expect that he bumped into Yu Jin, and at that time he found that this woman has an extraordinary physique, and if she can be used by him, she will definitely be able to help him cultivate greatly.

At that time, Han Yefei wanted to do it, but at that time, there was a messenger in the Immortal Palace, and it was inconvenient for him to do it, so he just put a hidden spell on this woman to cover up her special physique.

Back in the Heavenly Demon Valley, I didn't think about tea and rice when I flew in the cold night, and I thought about how to bring it back from Wanxian Island Yu Jin every day.

Originally, with his identity and strength, he could send a high-level monk to infiltrate and Yu Jin directly arrest him. But this cold night flying has always been cautious, he knows that if he sends a demon cultivator with advanced cultivation into Wanxian Island, it will definitely alarm the high-ranking monks on the island, and when the time comes, it will be a big trouble to mistakenly think that the Heavenly Demon Valley has a bad heart.

Moreover, as soon as the high-level monks are dispatched, it is easy to arouse the vigilance of all parties, in this world, the situation of each force is extremely complicated, not only the other forces of the Asgard Palace, but also the same, they don't know how many eyeliners are inserted into each other.

Pulling a hair and moving his whole body, this made Han Yefei directly give up the most direct method, and chose to use a painting god monk to sneak into Wanxian Island.

This person's name is Sun Chi, and he is a close confidant of Han Yefei.

Originally, the idea of flying in the cold night was to let him secretly arrest people, but unexpectedly, this Sun Chi had selfish intentions.

It's not that he also fell in love with Yu Jin, but he fell in love with the prosperity of Wanxian City, the realm of the Immortal Palace is different from the Heavenly Demon Valley, not only is there abundant resources here, but he has no constraints when he leaves the Heavenly Demon Valley.

He began to send his subordinates to do whatever he wanted on Wanxian Island, not only killing people and taking treasures, but also capturing many mortals for him to practice.

Of course, Sun Chi did not forget the instructions of the young master Han Yefei, he happened to subdue Yu Jin's eldest cousin, and seeing that Yu Jin's eldest cousin had a grudge against his family, he wanted to use him to arrest Yu Jin.

Unexpectedly, the eldest cousin was also uncontrollable, and he did carry out half of the execution, but he did not take the person away immediately, but was ready to do something to the rest of the family, and he thought about taking back his cousin. It's only been a long time since I started.

It was also his selfishness that gave Yu Yuanwai time to inform Wanxian City, which led to the previous scene.

By the way, two years ago, Xiao Feng and the others hunted and killed the Sea Spirit Monkey in order to receive the Young Master of the Heavenly Demon Valley and others.
