Tian Yuan took the Thunder Flame Giant Sword, his figure disappeared, and the next moment he appeared on the Thunder Lake.

"Xuanwu Sword Technique!"

Before the words fell, Tian Yuan brandished the Lei Yuan giant sword and slashed towards the sky.

The momentum was like a rainbow, and the sword qi was like a dragon swallowing the sun, shooting towards the sky, and in an instant, Tian Yuan slashed out more than hundreds.

Suddenly, I saw that on the calm canopy, spatial cracks spread like spider webs.

The power of Tian Yuan's wave of his hand dazzled De Yunfeng, and the power brought by that sword qi made him feel a great shock.

"Xuanwu sword, suppress the ten directions!"

In the end, Tian Yuan shouted violently, and then slashed out with a sword!

At the same time, a fierce but incomparably thick sword qi centered on Tian Yuan slashed towards all directions like a wave.

Then, a shocking scene appeared, only to see the sword qi slashing towards the place where the sky and the earth were connected like a large wave blade.

In the next moment, I saw that there was a circle of openings cut by the wave blade in the place where the surrounding heaven and earth were connected.

The mouth is directly disconnected.

It was the scene where the space was cut off, as if the place where the sky and the earth were connected was cut off, the sky was the sky, the earth was the earth, and it was clearly distinguished!

Tian Yuan appeared in front of Yun Feng's eyes in the next moment, and the sword qi also dispersed, but all the spatial cracks that were cut out did not close immediately.

Rather, it healed at an extremely slow pace, as if it had been blocked by some force.

"This ...... Xuanwu Sword Technique?" The scene in front of him shocked De Yunfeng, "This is the swordsmanship martial art that Master Zun wants to teach me?"

Yun Feng's eyes lit up, and the scene in front of him made him a little impatient.

"This Xuanwu Sword Technique, cultivated to the fullest, can derive a suppressive force. It is the power of Xuanwu, which can suppress all things. ”

"This spatial crack that I cut open can't be closed for a long time, and it was suppressed by the power of Xuanwu. ”

Tian Yuan said.

"I can also refine to such a realm?" Yun Feng looked at the spatial cracks on the canopy, looking forward to it.

"Hmph, no. Tian Yuan smiled, "How old is your kid to cultivate? ”

Yun Feng smiled embarrassedly, he didn't expect this, but he was a little confused by the scene in front of him.

"Let's start cultivating, this martial art was also robbed by me back then, and I also practiced it when I got it, and it was also one of the best martial arts among the generations of the same level at that time. ”

Tian Yuan said with a smile, but he said it lightly, and he didn't want to retain his noble character in front of Yun Feng at all.

Yun Feng didn't care about Tian Yuan's words, as if he agreed with what his master had done back then.

"You should practice the method first. ”

Tian Yuan said: "According to the method, guide the spiritual power ......"

Subsequently, Tian Yuan told Yun Feng the mantra of the Xuanwu Sword Technique one by one, and also explained it to Yun Feng one by one.

With Tian Yuan's explanation, Yun Feng's expression slowly became solemn.

According to his expectations, the difficulty of cultivating this Xuanwu Sword Technique was definitely more difficult than his existing martial arts three-pole slash, and it was also difficult to dominate the fist.

However, after listening to Tian Yuan's explanation, Yun Feng realized that he had underestimated the difficulty of cultivating the Xuanwu Sword Technique.

According to Tian Yuan's words, the difficulty of cultivation is many times more difficult than the Three Extremes Slash, and the Hegemony Fist is not known to be many times more difficult.

The first is to draw one's own spiritual power through the whole body, and then take the dantian as the foundation to give birth to the power of Xuanwu.

It is easy for spiritual power to penetrate the whole body, but it is extremely difficult to nurture the power of Xuanwu.

Because to nurture the power of Xuanwu, you must use the blood of Xuanwu as a guide to give birth to the power of Xuanwu.

"Master, without the blood of Xuanwu, how can I cultivate?" Yun Feng said helplessly, but he thought about it, it should not be unintentional for Shizun to let him cultivate this Xuanwu Sword Technique, he should be prepared to teach it to himself.

Xuanwu is an ancient divine beast, and it is said that it will be ranked in the top ten on the list of divine beasts.

Yun Feng didn't know who was so powerful to create the Xuanwu Sword Technique like this, but Yun Feng guessed that that person must be an amazing person.

"The Xuanwu Divine Beast is one of the top ten divine beasts of ancient times, and his blood is naturally not available to ordinary people, but I have the blood of Xuanwu. ”

Tian Yuan's words, Yun Feng was not very surprised, with his understanding, Tian Yuan and Yan Tian and other characters, to get the blood of Xuanwu should be a simple matter.

"Still. ”

This time, it was Yan Tian who came to Yun Feng's side, and his old face was full of smiles.

It's just that this smile made Yun Feng's scalp a little numb.

"That, Master, you... What do you say?" Yun Feng asked worriedly.

"Hey, why do you have a feeling of fear when you see me?" Yan Tian said earnestly: "Alas, Shizun is not a demon, what are you afraid of, really, you are so timid, not like my Yantian apprentice." ”

"No, am I afraid?" Yun Feng raised his courage a little, "You go on, but what?"

"Hehe, it's just that the power of the bloodline of Xuanwu Blood is too strong, with your current physique, you may explode and die before you refine it. Yan Tian smiled, and his old face was like a gorgeous chrysanthemum.

Yun Feng had a bad premonition, and asked in a low voice, "Then, how can we succeed in refining?"

"That's physical training!"

Yan Tian said with a smile: "Although your physique has been awakened by the Holy Body, coupled with the tempering of the power of thunder, it can be said that your physical body is stronger than the defense power of ordinary spirit treasures. ”

"So...... Still...... Is it okay to enter the Thunder Lake to refine the physique?" Yun Feng's psychology inexplicably appeared at this moment, and the kind of tormenting pain in the Thunder Lake appeared.

"Bang!"

A feeling of pain was heard, and the cloud wind howled loudly.

"Old fellow, you like to kick people's butts so much, can't you let me in by myself?"

"Ah...... Whew......"

"Boy, in order to become a peerless powerhouse, you must have the ability to endure hardships, look at you like a bear, and you still want to become a peerless powerhouse, it's just a joke. ”

Seeing the clouds and winds howling in pain like killing pigs in the Thunder Lake, Yan Tian gloated and said cool words.

But Yun Feng didn't care what Yan Tian said, at this moment, he felt as if his flesh and bones were burned by the flames, and the bone marrow was like the refined iron in the flames being forged.

But although the cloud wind howled like a pig, it did not sweep away to the shore.

Yan Tian is right, if you want to become a peerless powerhouse, you must be able to endure hardships that ordinary people can't endure.

What is this bitterness!

"Ahh

Yunfeng shouted, "Come on, Lao Tzu can't endure any hardships, isn't it just refining the body, it's the same as playing." ”

"Ah...... Oh...... Woo"

......

On the shore of Thunder Lake, Yan Tian and Tian Yuan got a deck of black and white chess out of nowhere, and began to play chess leisurely.

The two of them turned a deaf ear to Yun Fengna's pretending to be forced and then screaming at the sound of killing pigs, and directly ignored it.

Time passed slowly, and Yunfeng spent his days in the Thunder Lake like a year, and he actually survived five days.

At this moment, there was no screaming like killing a pig in the Thunder Lake, and the chess game between Yan Tian and Tian Yuan also stopped.

"Is this kid burping? Yan Tian looked gloating, and said so in his mouth, but there was a relieved smile on his face.

And Tian Yuan didn't answer Yan Tian's words, and quietly watched the thunder lake with his hands behind his back.

Under the gaze of the two, in the thunder lake, the calm lake finally moved.

I saw a figure slowly emerge from the thunder lake in a cross-legged posture.

In a moment, the whole figure completely appeared, sitting cross-legged on the surface of the lake.

The figure was half-naked at the moment, and its entire body was a dark gray, on which thunder arcs lingered.

Under the handsome face, the whole body is clearly lined, and a vague tenacious aura comes faintly, giving people a sense of indestructibility.

Above the Thunder Lake, Yun Feng slowly opened his eyes, and his originally black eyes turned silver, and a faint trace of thunder flashed in them.

Yun Feng's eyes blinked, and then his original dark and deep eyes returned.

"Lei Yuan's body!"

Tian Yuan and Yan Tian glanced at each other, and Tian Yuan nodded.

"It's finally a little bit done. ”

Yan Tian also smiled with relief, "If the disciples you and I teach are also mediocre, then we will be killed by ourselves." ”

"For the refining of Xuanwu blood, it should be successful. The Heavenly Elder also had a look of relief in his eyes.

"But there's still a long, long way to go. ”
