Ning Xiu thought that Yun Lao had mentioned to him that the Nether Slash was made from the blood crystal of the nine-tailed fox and a piece of hand bone of the Shura Patriarch.

Another strength in the mouth of the Nine-Tails Princess......

Could it be the hand bones of the Shura Patriarch?

He looked at Sen Bai's hilt, his eyes flickered, and then he used his true qi to enter the hilt, but the true qi gradually filled the Nether Slash along the hilt.

"Fool, you can't tap that power at all."

Princess Nine-Tails' voice sounded in his head.

Ning Xiu was not annoyed when he heard this, "Please ask the princess for advice." ”

"I want to go."

The Nine-Tailed Princess didn't say much, and her voice disappeared.

"The princess wouldn't be unaware."

Ning Xiu wanted to use the method of agitation to provoke it.

But it didn't work, the nine-tailed princess was still silent, and there was no reaction.

Ning Xiu didn't ask anymore, he wanted to find out the secret of the Netherworld Slash by himself, he thought about it, and planned to go to Yun Lao.

This knife was made by the other party, and the other party should know better.

Come to the residence of Yun Lao at the outer gate.

Finding that the Shura Sect Master was also here, the other party also came to visit Yun Lao, and when he saw Ning Xiu coming, he glanced at the other party and smiled slightly, "Ning Xiu, are you also coming to visit Yun Lao?" How's it going, Nether Slash is still going well? ”

"That's what I'm here for."

Ning Xiu said, looking at the Shura Sect Master, he thought for a moment and asked, "Sect Master, I am holding this knife, is there no problem?" ”

After all, the Netherworld Slash is the property of the Shura Sect, and it is also a powerful peerless fierce soldier, and it is a treasure of the Zhenzong in any sect.

"Heh, naturally there is no problem, you just keep it, anyway, except for you, there is no one else in this Shura Sect who can use it."

The Shura Sect Master smiled.

No matter how good the weapon is, it must be in the hands of people to be able to exert its power, otherwise, it is basically a dead thing.

The Shura Sect Master naturally knew this truth, so as long as Ning Xiu was not unfavorable to the Shura Sect, he didn't mind letting the other party hold this knife all the time.

"Ning Xiu, do you have any questions for me about Nether Slash?"

Yun Lao asked curiously.

Ning Xiu noticed that compared to the previous two days, the other party's face was much better, except for the empty sleeve on the left, Yun Lao looked full of energy.

"To be precise, I want to ask about the Shura Patriarch."

Ning Xiu knew that since the hand bone was left by the ancestor of the Shura Sect, it was better to start with the life of this ancestor first.

"Master Zu is a character from 1,200 years ago, according to legend, Master Zu is extraordinary, and he reached the realm of heaven and man with only one Jiazi, and then single-handedly created the Shura Sect, at that time, the Shura Sect was there, and in terms of scale, although it was far less than now, no one dared to provoke it."

"Later, Master Zu didn't know when he broke through the realm of immortality, left the Shura Sect, traveled to Houtu, and returned again three hundred years later, and the returning Master Zu seemed to be deeply injured, and after holding on for sixty years, he sat down, leaving a piece of hand bone in the same place...... "Yun Lao said eloquently.

And these are all things he saw in the classics.

After Ning Xiu heard about it, he felt that it was of no help to him, and continued to ask: "What kind of martial arts did Master Zu use during his lifetime?" ”

"Rakshasa trick, there is another ...... Netherworld Shura Knife Technique! ”

"Netherworld Shura Knife Technique?!"

"Well, this sword technique is the supreme sword method of the Shura Sect, and it is rumored to be a heaven-level exercise, but it is very difficult to practice this technique, except for the ancestral master, the sect masters of my Shura Sect have not been able to practice successfully."

"Where's this knife technique?"

"The first peak, Netherworld." Yun Lao said.

Perhaps, this Netherworld Shura Sword Technique is the key to mastering the secret of Netherworld Slashing, Ning Xiu thought like this, and looked at the Shura Sect Master.

And the other party also guessed what he was going to do, and smiled, "It's not impossible for you to go to the Netherworld Valley, the Netherworld Shura Sword Technique, no one can learn it since the ancestor master, if you can succeed, it will be a good thing." ”

"Thank you, Sect Master."

"Tomorrow you come to the first peak to find me, and I will take you to the Netherworld Valley."

"Okay."

Ning Xiu nodded.

When he returned, he saw Xue Buzhi outside the door, and the other party had obviously been waiting here for a while.

Ning Xiu stepped forward and said, "Sister Xue, why don't you go in?" ”

"Your master hasn't come back yet, how can I trespass without permission."

Ning Xiu rolled his eyes, "Sister Xue, why are you and me so outside, come in quickly." ”

He welcomed Xue Buran into the house and poured him a cup of tea.

Xue Buyan took out the pill and handed it to Ning Xiu, saying, "This is the Snow Lotus Pill I asked for from my master, I think it will help you." ”

Ning Xiu smiled and patted his chest, "Sister Xue, don't worry, I'm in good health, those undercover agents are not my opponents at all." ”

"I also heard from Shizun about your complete plan after I went back, but I didn't expect you to be so bold and use your example as bait to lure out the undercover agents of the Purple Lotus Sect buried in the Shura Sect, eradicate them in one fell swoop, and even put lightning locks on yourself, it's really too risky." Xue Buyan said.

After hearing Bai Feifei's story, she was still a little shocked.

Ning Xiu was too bold to do this.

If something goes wrong in the middle, it will be a catastrophe.

"Ha, Sister Xue rest assured, I dare to do this, naturally I have confidence, am I not intact?"

"Yes, I didn't expect that in such a short period of time, Ah Xiu has grown to such a point, which is beyond the reach of me, who is a sister."

Xue Buyan said with emotion.

Although she is one of the most gifted disciples in the history of the Shura Sect, it takes time for talent to transform into strength.

She hadn't been in Houtu long enough.

But Ning Xiu's hanging wall is different, his strength has advanced by leaps and bounds, and in a day, the Yuanhai realm can be lifted.

Simply inhuman.

He has completely left behind the group of people who came to Houtu with him.

"Sister doesn't have to be presumptuous, with your heavenly posture, over time, you will definitely be able to break through the heavens and become a strong person in the future."

"Hmm."

Xue Buyan nodded.

She also wanted to catch up with Ning Xiu as soon as possible, instead of watching from behind.

"Speaking of which, I don't know how the sect leader is doing now."

Xue Buyan showed a look of wistfulness on his face.

Ning Xiu was stunned for a moment, and there was a trace of longing in his eyes.

Li Qingzhi......

He also misses each other a little bit.

At the beginning, the red-clothed sword immortal said that Li Qingzhi was the reincarnation of the immortal and took her away, but now he doesn't know if the other party's immortal qi has been refined? I don't know if I was affected by the memories of the Immortals......

I don't know if the other party is in Houtu or Da Zhou now.

Or, on some other continent.

In addition, the origin of the red-clothed sword immortal was also very unusual, and he had checked some information about the other party during this time.

I only know that this red-clothed sword immortal has appeared a few times in Houtu.

But every time it appears, it is very amazing, and the strength shown is even more incredible, and he once killed a ...... with a sword Fugue!

"Invincible Begins with Sacrificing to the Ancestors"

The strength of the other party may be a celestial!

Or, on top of that.

"With the red-clothed sword fairy taking care of it, the master should be fine."

Ning Xiu shook his head and suppressed the feelings of longing in his heart, the most important thing now is to practice, practice, or practice.

He didn't want to see Li Qingzhi next time, the other party had become an immortal, and he was still just Yuan Hai, so he would be suppressed by the other party.

The corners of Ning Xiu's mouth curled slightly.

The next day.

He came to the first peak alone, and in this Mahavira Treasure Hall, the Shura Sect Master was already waiting, and said to him, "Come with me." ”

He jumped out of the main hall and jumped off a cliff.

Ning Xiu followed.

On the way, he asked, "Sect Master, how is the war with the Purple Lotus Sect?" ”

"Well, it's going well, the Purple Lotus Sect has lost several fugue powerhouses this time, except for one Purple Lotus Sect Master, there are almost no masters in charge, and the Purple Sect will personally take action and lead people to the expedition, and now most of the territory of the Purple Lotus Sect has been pocketed, and the next step is to prepare to attack the Purple Lotus Sect's helm, after taking you to the Netherworld Valley, I plan to take a trip in person."

"Then I wish the sect master success."

Ning Xiu didn't plan to go together.

The Purple Lotus Sect is already at the end of its power, and it can't afford to stir up any storms.

The most important thing for him now is to understand the secrets of Netherworld.

Soon, he followed the Shura Sect Master to a valley, which looked quite beautiful, with long grass and warblers flying, birds singing and flowers.

It has nothing to do with a name like Netherworld.

I don't know why I got such a name.

Gradually, Ning Xiu came to the depths of the valley, and his expression became solemn, although the surrounding scenery was still beautiful, but he noticed something strange in the air, a sense of slaughter, permeating the surroundings.

He came to the source of the murderous intent.

It was a mountain wall, and there were knife marks on the mountain wall, and the knife intent revealed in the knife marks was the source of the killing intent, and as Ning Xiu came to this mountain wall, he carefully looked at the knife marks on it, and suddenly, the infinite knife intent seemed to turn into a fierce ghost rushing towards him.

That awesome ghost, it's too real.

It was so real that Ning Xiu couldn't help but take two steps back.

With such a knife mark hidden, it's no wonder it's called Netherworld......

"This is the Netherworld Shura Sword Technique."

Shura Sect Master Turbulent Dao.

But on the mountain wall, there are no characters, no moves.

There was nothing else except for those countless knife marks, which made Ning Xiu feel stunned, how to practice like this?

He looked at the Shura Sect Master with a strange look in his eyes.

It seems to be saying, Sect Master, are you teasing me?

And the Shura Sect Master smiled helplessly, "I didn't lie to you, this is indeed the Netherworld Shura Sword Technique, this sword technique has exceeded the level of ordinary martial arts, it can only be understood, not spoken, the ancestor will contain the sword technique in this knife mark, but whether or not it can be comprehended depends on the individual's understanding and creation." ”

Ning Xiu was a little skeptical.

These knife marks are chaotic, and they really contain heaven-level martial arts?

But there was no need for the Shura Sect Master to lie to him.

"Okay, you can take your time here."

The Shura Sect Master said to Ning Xiu and patted him on the shoulder to express encouragement.

To be honest, after so many years, no one has been able to cultivate the Netherworld Shura Sword Technique, and he has no hope that someone will be able to cultivate this Sword Technique.

But Ning Xiu's appearance gave him a glimmer of expectation.

Perhaps, the other party can do it?

After the Shura Sect Master left, Ning Xiu stood alone in front of the mountain wall, and the sword intent revealed by the countless knife marks rushed to his face, and the evil ghosts in the sky kept appearing in front of his eyes, as if they were about to devour him completely.

Although knowing that it is just an illusion.

But it was so real, just after looking at it for a while, a layer of fine cold sweat had already appeared on his forehead, and he felt a burst of mental exhaustion.

"Just looking at these knife marks makes me feel a headache, let alone comprehending the Netherworld Shura Sword Technique from these knife marks."

"No wonder no one has been able to learn it for so many years."

Ning Xiu took a deep breath, his heart was clear in his mouth, resisting the impact of the sword intent, and his eyes were staring at the mountain wall.

But after watching it all afternoon, I still didn't gain anything.

"Is this really a knife technique?"

"Wait......"

Ning Xiu suddenly thought of something, and patted his head, "I'm really a lake, is there a knife technique here, don't you know if you go up and touch it." ”

He's systematic.

If there is really a sword technique in this mountain wall, then he can go up and touch it to automatically simplify, where is the need to work hard here?

Thinking of this, he walked quickly towards the mountain wall.

But as he got closer to the mountain wall, the sword intent he felt became more and more powerful, and the demons around him became more and more vivid.

After only a dozen steps, he broke out in a cold sweat.

Even if there is a pure heart and no dust, I feel a lot of pressure.

"How long has this ancestor been dead, I didn't expect that the knife marks he left behind still have such terrifying knife intent?!"

"The realm of immortality is indeed mysterious."

Ning Xiu said with emotion.

He felt that in order for him to come into contact with this mountain wall, he had to first overcome the influence of the sword intent, and the sword intent directly acted on the spirit.

Therefore, he has to improve his mental strength first.

Thinking of this, he directly took out a large jar of hundred-year-old wine, mixed it with the powder of the best white jade, and poured a big sip with a gurgling mouthful.

These things can help him cultivate spiritual power.

Time flies.

Seven days passed.

Ning Xiu's spiritual power has improved a lot, and even with his true qi, he has increased from the forty-fifth level of Yuan Hai to the forty-sixth level.

He continued to try to get closer to the mountain wall, but eventually stopped fifty feet away from the mountain wall.

"We have to keep it stronger."

Ning Xiu thought about it and practiced for another seven days.

The spiritual power was strengthened again, and the true qi cultivation was also raised to the forty-seventh level.

This time.

He stopped thirty feet in front of the mountain wall.

Then he ran into a problem.

The wine is gone.

"Looks like we're going to have to buy some wine first."

Ning Xiu secretly thought to himself that this was not a difficult matter, so he went out of the valley and went to the inner gate area to buy dozens of jars of century-old wine.

On the way, I inquired about the war of the Shura Sect and the Purple Lotus Sect.

I learned that the Shura Sect Master had rushed to the Purple Lotus Sect's chief helm ten days ago, started a big battle with the Purple Lotus Sect Master, and finally won.

Now, the Purple Lotus Sect has been completely defeated.

The Shura Sect won a great victory, and the entire sect realm was full of joy.

However, what made Ning Xiu quite concerned was that the battle report only mentioned that the Shura Sect Master had defeated the Purple Lotus Sect Master, but did not explain the life and death of the Purple Lotus Sect Master.

Was the war report negligent?

Ning Xiu didn't think much about it, returned to the Netherworld Valley with the wine, and continued to challenge the mountain wall while cultivating spiritual power.

There is quite a tendency not to practice the Netherworld Shura Knife and vow not to give up.
