When Kuang Shiyun saw it, he also disappeared.

Two miles away from the palace, there is a mountain peak thousands of meters high, and the peak is full of strange rocks and no plants. In front of this mountain peak, there were two people, one with gray hair and beard, wearing a gray robe and holding a large ring knife, and the other wearing a black suit and silver hair.

These two people were the old man of the Underworld Demon and Kuang Shiyun who were still in the palace just now.

Just when the old man of the underworld smiled at Kuang Shiyun, Kuang Shiyun understood that this demon wanted to test the power of the broken knife, so after the demon disappeared, he was not nervous at all, and teleported to follow.

At this moment, the old man of the underworld closed his eyes, turned his back to Kuang Shiyun, and faced the stone mountain.

The broken knife was in his hand, and it no longer trembled, as if it had agreed with him.

The knife has not yet been chopped, but the momentum of the broken knife has begun to cover the surrounding area of hundreds of meters.

Some small stones and dust on the stone mountain, as if they had no weight, overcame the gravitational pull of the earth and floated upward, and Kuang Shiyun, who also felt the tightness in his chest, sighed slightly and retreated, observing the movements of the old man from a distance.

Suddenly, the old man's eyes opened, and a fine light shot out of his eyes, followed by the big ring knife in his hand, and suddenly the light was great. Kuang Shiyun saw that the broken knife was as dazzling as the sun, and he had to block the light with his hands.

Then, the old man of the demon held the broken knife and slashed down very slowly.

Even Kuang Shiyun, who was very far away from the old man of the underworld, seemed to feel that the heavens and the earth had changed color at this moment, and the entire space was frozen, and he couldn't raise his hand to resist the fierce stones.

Although the old man's broken knife slashed very slowly, it was not small at all.

When the old man of the Underworld completed the entire downward splitting action, the entire stone mountain turned into powder in an instant, and at the same time, the entire space shook violently as if an earthquake had occurred.

Even, the Heavenly Mirror let out a trace of sorrow because of this attack, which made the unknown Emperor Yuqin wonder.

Kuang Shiyun watched the power of the old man's use of the broken knife, and couldn't help but smack his tongue secretly.

In the past, when he used the broken knife, he didn't have such a feeling at all, even if he was holding an artifact in his hand, an ancient artifact of ancient times, but it was only used as an ordinary spiritual weapon, but this "spiritual weapon" was a little sharper and harder than other spiritual weapons, and he never thought that this artifact could exert such power.

Actually, this is not the real strength of the broken knife.

Because the old man of the Underworld Demon was afraid that he would damage the Heavenly Mirror, he only used half of his power to urge the broken knife, but he didn't expect that the power of the broken knife was greatly beyond his expectations.

"Haha, it's really powerful, it's really powerful, it's really worthy of being the most powerful artifact in heaven and earth. The Old Man was clearly very satisfied with his perfect blow, and gently stroked the blade of the broken knife, exclaiming loudly.

"Hades Demon, I didn't expect that your knife just now was so powerful, and the entire space seemed to be condensed. Kuang Shiyun also flew over at this time, and the impact of the blow just now had completely disappeared at this time, and when he saw the old man of the underworld admiring the broken knife, he couldn't help but praise his sword skills.

"Of course, among the ancient cultivators, my Demon has recognized the second in the sword technique, and no one dares to recognize the first. The Demon looked very happy and said to Kuang Shiyun with a grin.

"Na, also, seriously, this broken knife is so powerful, I'm really reluctant to give it back to you, hahahaha. After the demon finished speaking, he threw the broken knife in his hand to Kuang Shiyun and laughed to himself.

Kuang Shiyun caught the broken knife with one hand, and also learned from the underworld, using the horizontal knife as his chest, and then slashed out with a knife.

It's a pity that not only did the broken knife not emit any light, but not even a single blade was seen.

"Hmm, what are you doing?" the old man asked strangely, looking at the appearance of Kuang Shiyun's sword.

"Cleaver. Kuang Shiyun turned his head and looked at the old man of the demon very strangely, thinking, why can't he even understand such movements?

"You also call it a chopper?" When the old man heard Kuang Shiyun's words, he actually exclaimed exaggeratedly, "Didn't your master teach you how to use a knife?"

"Yes, yes, look!" After speaking, Kuang Shiyun treated the broken knife as a flying knife, and controlled the attacks everywhere through a trace of true yuan, only to hear bursts of explosions, and countless trees fell.

"Stop, stop. The old man of the demon shouted loudly, and then looked at the broken knife lying in Kuang Shiyun's hand with a distressed face, "What do you call a knife? ”

"What?" "This time, Kuang Shiyun didn't follow, how can he say that this Chaos Heavenly Mansion's imperial sword, the imperial sword technique can also be said to be a relatively clever method, how did it become a nonsense in the eyes of the old man of the underworld?

"Of course, you don't use a knife at all, just find a random weapon for you, and you can use it like this. The old man of the Demon Demon didn't see Kuang Shiyun's exaggerated expression, and continued, "In fact, the way of the knife is to pay attention to the unity of the heart and the knife, the so-called unity of the heart and the knife, that is, your heart is the knife, and the knife is your heart. Think about it, if you are like you, you go around cutting people with your heart, will it be easy for you to be hacked to death?"

When Kuang Shiyun heard it, he felt that it made sense, but after thinking about it, he felt that it didn't seem to be, and he didn't know how to answer the old man for a while.

"Alas, what a bastard, what a waste of a broken knife in your hands. After the demon finished speaking, he sighed, ignored Kuang Shiyun, and directly teleported back to the palace.

"Huh?" Kuang Shiyun couldn't help but be stunned when he heard the words of the underworld, and he didn't know what to do with the broken knife in his hand.

"Tianfan!" Suddenly, the voice of the Void Demon Ancestor appeared in Kuang Shiyun's mind.

"Big brother!" Kuang Shiyun exclaimed in surprise, since he came to the Desire Realm, the Void Demon Ancestor had not been in contact with Kuang Shiyun, so Kuang Shiyun had always thought that he was in retreat, and he couldn't bear to disturb him even when he was in danger.

"Well, I think you also saw the old guy of the Underworld Demon using the Broken Knife just now?" The Void Demon Ancestor's slightly vicissitudes of life resounded in Kuang Shiyun's mind.

"Yes, big brother, the skill of the demon with his knife is really terrifying, and with a casual knife, he can exert such a terrifying power!" Kuang Shiyun said, and he couldn't help but tremble in fear, thinking that if such an attack fell on him, he didn't know what he would become!

"Well, that's right. Even in ancient times, the old man of the underworld could be called a strong man, and his sword path could even be called unique, unmatched. So, if you have the chance, ask him for advice or two, and then you will be able to exert the power of the broken knife. ”

When Kuang Shiyun heard this, his eyes couldn't help but light up: "Yes, why didn't I think of it? Thank you for your guidance!"

"Well, okay, I'm going to meditate too, his knife just now brought me a lot of realizations, if I understand it, maybe I can leave the broken knife and get the opportunity to reshape my body. ”

"Well, big brother, you go. After Kuang Shiyun finished speaking, he turned around and glanced at the palace not far away, and flew over.

Kuang Shiyun flew very slowly, because he didn't know how to speak to the Underworld.

I've been thinking about various plans in my heart, and I've vetoed them one by one.

Until he came to the gate of the palace, he still couldn't think of a good way, so he had to walk in.

When I went in, I saw that the old man was already sitting on the original chair, his eyes closed, as if he was closing his eyes and recuperating. As soon as Kuang Shiyun walked in, the old man of the underworld demon opened his eyes, and his eyes looked at Kuang Shiyun with dripping eyes, as if there was something wrong with Kuang Shiyun.

Seeing the old man looking at him like this, Kuang Shiyun couldn't help but look down at his clothes, and then observed his whole body with his mind, and after finding that there was nothing wrong, he asked the old man of the underworld: "Demon, what are you looking at?"

The demon monster rolled his eyes, and then said with a smile: "Boy, do you want to learn my sword way?"

When Kuang Shiyun heard this, he was overjoyed, he didn't think of a way to let him teach himself when he wanted to be bald, but who thought that he himself would mention it: "Yes!

"If you want to learn my sword way, you have to agree to my two requests. Seeing that Kuang Shiyun had taken the bait, the Demon of the Underworld continued to talk and put forward two conditions, "First, I must leave a Dao system in the Desire Realm or the Cultivation Realm and carry forward my Dao Dao. ”

"Well, that's fine, but only if I can leave this Heavenly Mirror and escape the pursuit of the rest of the Desire Realm. As soon as Kuang Shiyun heard this, he immediately took over and said.

The old man of the Underworld slanted a glance at Kuang Shiyun, ignored his words, and continued: "Second, you want to help me kill that kid without a trace for me. ”

When Kuang Shiyun heard this, he was so frightened that his jaw fell to the ground.

Who is Traceless? Even the old man of the Underworld Demon lost at his hands, and besides, the ancient period was tens of millions of years away from the present, and no one knew how far his current cultivation had improved.

This old man of the demon actually let himself kill without a trace, it is better to kill himself now.

"Why, don't you dare?" Seeing Kuang Shiyun looking at him dumbfounded, the old man of the Underworld Demon thought that he had a weak heart.

"It's not that I don't dare, but with my current cultivation, even Emperor Yuqin can't beat him, how can I kill Wuxian without a trace?" Kuang Shiyun said with a look of grievance.

"It's not for you to kill now. When you become a real demon emperor, plus the sword path that has been condensed from the essence of my life, hehe, even ten traceless ones are not your opponents. The old man of the underworld laughed happily as if he had really seen Kuang Shiyun kill without a trace.

"Oh, yes, I promise you. Kuang Shiyun let out a long sigh, since he didn't kill it now, it would be easy to do.

"No, you have to swear first, I can't trust you kid. The old man looked at Kuang Shiyun with the eyes of a liar, only to see that he was covered with goosebumps all over his body.

Seeing the serious look of the old man of the underworld, Kuang Shiyun knew that there was no way to dodge, so he could only shake his head with a smile and raise his palm to the sky, "I, Kuang Shiyun today, I swear by my soul that after learning the sword path of the underworld, I will carry forward its sword path and kill it without a trace. ”

After speaking, a trace of soul power dissipated between heaven and earth with Kuang Shiyun's words.
