This Extreme Black Cold Stone was produced in the mythical and legendary Hell, and it was extremely cold, which was just right for him to cultivate the Yin and Netherworld Qi.

Moreover, there is no need to cultivate, as long as it is absorbed into the body, it will immediately become the Yin and Netherworld Qi, that is to say, this kind of stone itself is condensed from the Yin and Netherworld Qi.

This is great news.

Originally, he had just almost practiced this Yin Qi to the extreme, but unfortunately he was interrupted in the middle and fell short, but this time, he was hidden underground, practicing with peace of mind, and no one could disturb him anymore.

No, this underground cave is very strange, and there are extreme black cold stones that only exist in myths and legends, so I'd better be careful and take a look at it first.

He had just been interrupted in the middle of his practice, his mind was traumatized, and he almost went mad, and this situation could not happen again.

Yang Zhen planned to see clearly first, or at least to find out if there were any ancient creatures in the depths of this cave.

He walked in all the way, taking the opportunity to make a fortune all the way, and pieces of extreme black cold stones were dug down by him and thrown into the Yandi Jade Seal.

These myths and legends are produced in the speciality of hell, which is simply the best thing in the world to cultivate the Yin and Netherworld Qi, and every time Yang Zhen digs a piece and touches it with his hand, the severe cold immediately transforms into the Yin and Netherworld Qi in his body.

This process was very wonderful, and he hardly had to practice it on his mind, a large amount of Yin and Netherworld Qi was generated in his body, and his body was also undergoing earth-shaking changes.

"Wonderful, wonderful---" Yang Zhen walked all the way in, his heart was full of joy.

Every time you dig up an Extreme Black Cold Stone, grab it in your hand, and then throw it into the Yan Emperor Jade Seal, it only takes a few breaths to increase the Yin and Netherworld Qi.

Later, he held a piece in one hand and dug it with the other, continuously producing a yin and underworld aura.

In this way, you don't have to look for a place in the future, as long as you hold the Extreme Black Cold Stone in your hand, you can practice when you go there.

This time it was really a coincidence that he found such a good place, and if he walked on the surface, he would not have encountered such a good thing anyway.

The more Yang Zhen walked in, the more excited he became, especially when he saw the increasingly dense extreme black cold stones on the wall, Yang Zhen's saliva flowed out.

He Chu'er said that these are all high-grade materials, and they are only recorded in ancient books.

Generally, the things recorded in ancient books are either empty or really good.

Dig more Extreme Black Cold Stones today, and even if you leave the Heavenly Emperor Continent in the future, it will be of great use to a higher world or continent.

Yang Zhen dug a lot and went all the way to the depths.

If there were any high-level Xuan Scholars here at this time who saw the changes in Yang Zhen's body, they would definitely be shocked.

Ordinary Xuanshi must concentrate on retreat and sit cross-legged on their knees to practice supernatural powers, and it is possible for dozens or hundreds of years to meditate.

Like Yang Zhen, he cultivated his supernatural powers while walking, and holding a black cold stone in his hand could increase the aura of the underworld, which was unheard of.

And Yang Zhen's cultivation speed is getting faster and faster.

He started with an extreme black cold stone in the palm of his hand, and it took eight breaths to absorb it all.

After the Yin Qi in the Black Cold Stone was absorbed by him, it would turn into a pile of useless shatters and disappear into mid-air with a wave of his hand.

After Yang Zhen took hundreds of steps inside, a black cold stone would be absorbed in just two breaths.

The faster he absorbed, the more Yin Qi in his body would be, and he would appear in a state of perfection again.

At this time, he felt that one hand was too slow, and he grabbed an extreme black cold stone with each hand, and a large amount of Yin and Netherworld Qi poured into his body like a tide.

In his heart, in his mind, the gossip pattern of yin and yang became clearer and clearer, and it seemed that it would be successfully completed at any time.

"It's a pleasure, it's really a pleasure--" Yang Zhen never thought that cultivating a heaven-level supernatural power would be so simple, he could practice it while walking, talking, talking and laughing.

If his master Mo Tianzun knew Yang Zhen's current thoughts here, he would definitely vomit a mouthful of blood on the spot.

Yang Zhen was even thinking that as long as he brought back this Extremely Yin Black Cold Stone, even Mo Tianzun and the other elders of this sect would have the opportunity to cultivate the Yin and Netherworld Qi to the fullest.

This time, not only did he gain benefits, but he also had the opportunity to win over the elders in the door after he went back.

Just when Yang Zhen had cultivated to the peak again and had a chance to break through at any time, his eyes trembled violently, and he saw a light appear in front of him.

The underground cavern came to an end.

If Yang Zhen was practicing supernatural powers outside like just now, this was the most critical time, and it would be difficult to stop if he wanted to, and if he stopped, he would be injured, and he might even go mad.

It's the same reason as being attacked by the three masters of the Taiyi Sect just now.

Fortunately, this cultivation was different from the cultivation of any heaven-level supernatural power in history.

Other cultivations have a process of transforming all kinds of power into the power of the Burning Sun, the Yin and Netherworld Qi, but this time in the Extreme Black Cold Stone, it directly contains the Yin and Netherworld Qi, and there is no need to transform this process.

Yang Zhen said stop it.

He immediately stopped.

Because he had already felt that at the end of the passage, there was a more powerful Yin Qi oppressing.

This Yin Qi was even colder and colder than what he had absorbed in the Extreme Black Cold Stone.

Yang Zhen stepped out, and he felt a chill all over his body, and his limbs were almost numb.

What is this concept?

Yang Zhen's own cultivation of the Yin Qi is one of the most yin and coldest vitality in the world, such a thing as the Extreme Black Cold Stone, sent to the hands of a bone refining master like Meng Qinglan, as soon as she gets it, she may be frozen to death on the spot and turned into an ice sculpture.

However, Yang Zhen can absorb the power in the Extreme Black Cold Stone and use it, which shows his strength to resist cold.

But now, Yang Zhen has the feeling of being frozen into an ice sculpture.

Even Yang Zhen felt cold.

Yang Zhen can completely imagine, not to mention Fang Huairou, He Chu'er and the like, even if Ye Xuanyi, or even Ye Ziyi who I saw just now, is here, without a top-grade spiritual weapon to protect himself, he will definitely freeze to death directly.

Feeling the numbness of his limbs, Yang Zhen hurriedly took a deep breath, mobilized the power of the sun in his body, and roamed along his limbs, and suddenly his body warmed up a lot.

Only then can I come back to my senses and look at the front.

At the end of the passage is a huge stone cave, which is more than 100 zhang long and wide, like an underground world, an underground temple.

And the first thing that came into front of Yang Zhen was a forbidden array.

That's right, it's the formation.

Although Yang Zhen didn't understand the formation, he could see it.

This formation was surrounded by a dense and incomparably strong Yin and Netherworld Qi, which could not penetrate through both the naked eye and the divine thoughts.

The formation occupies half of this cave, and the Yin and Netherworld Qi is all around this cave, oppressing Yang Zhen's mind and making Yang Zhen have to use the power of the sun at all times.

If Yang Zhen had practiced the power of the scorching sun to the extreme, he would not be able to hold on to five breaths in front of this great array, and he would either escape or turn into an ice sculpture.

You must know that this yin and yin qi is not only 'yin', he also has 'yin'.

Hades represents hell and death, and it becomes an ice sculpture here, and there is only one end, and it dies on the spot.

"This is--- what kind of formation is this?" Yang Zhen didn't know anything about the formation, and stood in front of the formation in a daze, looking at it.

Fang Huairou blinked and turned her head to look at He Chu'er.

To say that He Chu'er is not as knowledgeable as Huairou in terms of realm, appearance, and knowledge, but he was born in the Heavenly Emperor Gate, worked as a guard in Tianbao Tower, and is proficient in material trading, which Fang Huairou can never compare.

More importantly, among the six major Xuanmen in the world, the formation of the Heavenly Emperor Gate is the most famous and powerful.

Of course, the premise is that the Tiangang Earth Emperor Scripture is still there.

"You think I'm useless?" He Chu'er shook his head with a wry smile: "Our Heavenly Emperor Gate was indeed famous for its formations back then, but since the Tiangang Earth Emperor Sutra disappeared, the formations have also fallen. ”

"Moreover, the formation of this sect is forbidden, and ordinary disciples have no chance to learn it, and they will not learn it. ”

In the Xuanmen world, supernatural powers and magic weapons are the most important, few people use formations to kill enemies, most of the formations are to guard the warehouse, protect the sect, etc., and there must be a few people who concentrate on the formation.

"However, I have come into contact with a lot of things in Tianbao Tower, in my opinion, this big array is very powerful, probably because of the big array, it condenses the Yin and Netherworld Qi, and then evolves some special rocks around it into extreme black cold stones. ”

"The Extreme Black Cold Stone condensed by the Great Array?" Yang Zhen was taken aback and muttered to himself.

To say that there are countless extreme black cold stones, it is normal to condense so many yin and underworld qi, but if it is said that there are extreme black cold stones produced by this large array, this is still necessary?

What kind of formation is this? What's in the middle of this formation?

Just when Yang Zhen was dumbfounded, there was a sudden long laugh in the big array.

"Hahaha, boy, you have a good vision, you can come here alive, and you can still see the extreme black cold stone condensed by this large array, are you a disciple of that sect? You can actually practice and absorb the Yin and Netherworld Qi? According to what I said, in the Heavenly Emperor Continent, only the Yin and Yang Heart Protector Sutra of the Flawless Sword Sect can absorb and practice, you are only concentrating, it is impossible for you to practice the heaven-level divine power? Are you a god and demon? Do you have a special physique? Can you absorb the Yin and Netherworld Qi?"

"No, you're a human race, isn't it? You, you still have the breath of a demon in your body? Your body is actually a low-grade spiritual weapon? Are you a human or a demon?"

This voice suddenly came out in the big array, and with a strong will, it reached Yang Zhen's ears.

"Buzz" Yang Zhen lost his mind for a short time, and his eyes became confused.

"My name is Yang Zhen, and I am a disciple of the Flawless Sword Sect, I ---"

"Yang Zhen, Yang Zhen. Fang Huairou and He Chu'er exclaimed in the Yan Emperor Jade Seal at the same time.

"Ah---" Yang Zhenmeng was awake, his body retreated again and again, and his face changed greatly.

Almost controlled?

When the man spoke, with a kind of magic, he actually controlled Yang Zhen's mind and made Yang Zhen tell the secret in his heart.

If he was alone, he would have been hit directly, but fortunately, he still took Fang Huairou and others with him.

"Senior, who are you?" Yang Zhen took a few steps back, retreated to the passage, and looked at the big array vigilantly.

As soon as this person came up, he wanted to control Yang Zhen, and he was obviously ill-intentioned.

"Are you a disciple of the Flawless Sword Sect?" The voice in the large array was a little surprised: "Then you see who I am?"

Whew, the great array began to change, and a large amount of Yin and Netherworld Qi separated to the left and right, revealing the true face inside.

Inside, there was a person.

That's right, Yang Zhen saw it clearly.

At this time, not far in front of him, sitting cross-legged, a scribe in Tsing Yi, living and being alone.

The green-robed scribe looked to be in his early thirties, with a handsome face and attentive eyes, and sat cross-legged on a huge stone, not moving, even when he spoke, not even his mouth, only the voice lingering in the cave.

"You -----" Yang Zhen saw him, and he really felt a little familiar, as if he had seen it there.

"It's him--" Fang Huairou in the Yan Emperor's Jade Seal screamed as if she had seen a ghost.

"Teach the Supreme. ”

"What, what, what did you say?" Yang Zhen looked at this man incredulously, and finally thought of who he was.

Before becoming an official disciple of the Flawless Sword Sect, Yang Zhen had been an introductory disciple in the Flawless Sword Sect for a year, and the first class of each introductory disciple was to pay homage to the portraits of the Supreme Masters of the Flawless Sword Sect in the past, so as to inspire them to have the day when they would become the Supreme Masters of the Sect in the future.

At that time, Yang Zhencai's introductory disciples, like most introductory disciples, didn't think so, and almost casually looked at it.

At that time, it was undecided whether he could enter the Xuanmen or not, and what he wanted to teach the Supreme.

That's why Yang Zhen felt familiar.
