The terrifying hurricane rolled up the gravel on the ground and smashed it towards Mu Yongyuan together.

The water in the river, like a waterfall, splashed countless splashes and landed on the bodies of the two people.

In just one breath, the two of them turned into soup chickens.

The blade tore through the air and went straight to Mu Yongyuan's neck, since he was going to fight, Liu Wuxian was going to kill the killer, and he would definitely not show mercy to his subordinates.

Yesterday, I fought with thousands of demons, and I gained a lot, and my combat effectiveness increased several times.

The suffocating sword qi permeated the four wildernesses, especially Liu Wuxie's true qi, which did not have any repulsion with the underground demon world, and the degree of compatibility was very high, it was simply incredible.

When ordinary people come in and exert their true qi, they must be harassed by demonic qi, resulting in the true qi not being very pure.

Liu Wuxian was different, his true qi was like a monstrous flood, not only did he not have any restrictions, but his strength was even stronger than that outside.

The Demon Realm appeared in the Taihuang World, and the rolling demonic qi poured out, forming a terrifying wave that was enough to destroy everything.

Mu Yongyuan was shocked, he had seriously underestimated Liu Wuxie's strength, and he could no longer measure it according to the True Dan Realm.

The long sword was unsheathed, slashed in the air, and the oncoming sword qi cracked inch by inch, worthy of being Tiangang Quadruple, and its strength was extremely terrifying.

"Collapse!"

Two completely different forces suddenly collided together, forming earth-shattering ripples, surging mercilessly towards the surroundings.

"Boom, boom, boom......"

The space seemed to explode, and the surrounding flowers and trees were instantly razed to the ground and turned into ruins.

A few demons who were foraging for food in the distance were so frightened that they fled instantly, not daring to linger for a moment.

The strong ripples, like a strong wind passing through, blew up together, and retreated more than ten meters away, only then could they stand still.

Mu Yongyuan's face was gloomy and terrifying, the blow just now made him feel a palpitation, he was not facing a person, but an eternal beast.

An even more powerful battle intent burst out from Liu Wuxie's body, and if he could devour a Tiangang Quadruple, his strength would increase a lot.

"Fight!"

Without hesitation, the body disappeared in place like an afterimage, and continued to fight together with the evil blade in hand.

The life-killing knife technique is endless, the knife technique is like flowing water, without any flaws, and every time the knife is chopped out, it can bring unexpected results.

When did Mu Yongyuan meet such an opponent, for a while, he was a little uncomfortable.

What is terrifying is not Liu Wuxie's sword technique, but his true qi, which is not below him, or even above him, which is terrifying.

Under the same conditions, his martial arts skills and true qi are far inferior to Liu Wuxie, except that the realm is slightly higher, his advantages are gone.

In the battle of life and death, he cannot be distracted.

With a little attention, the evil blade approached in front of him, firmly locking his neck, extremely tricky, like a ghost.

The situation is becoming more and more unfavorable for Mu Yongyuan, one wrong move, one wrong move.

After Liu Wuxian seized this gap, he did his best, and every knife could perfectly lock Mu Yongyuan's move changes.

The ghost pupil technique is even more invincible.

No matter how Mu Yongyuan changed his moves, the evil blade could find the flaws in his moves, which made Mu Yongyuan embarrassed.

The knife borrowed the power of the person, and the momentum was like a broken bamboo, and Liu Wuxie's whole person was fused with the evil blade, although it was not as good as the unity of the human sword, but it was not much different.

Now!

He is the knife.

The knife is him!

The sky is full of sword shadows and human figures, fused together, Mu Yongyuan has no way out.

Jian Xing'er stood in the distance, her little hand suddenly covering her mouth, looking at everything that happened in front of her in disbelief.

In her eyes, Mu Yongyuan is definitely the pride of the sky, in the assessment that year, Mu Yongyuan ranked in the top three, joined the terrain peak, and it took less than half a year to become an inner disciple.

The genius who used to make her look up to the mountains is so embarrassed today, and she can't find a way to face Liu Wuxie, who is the true pill eightfold.

"Liu Wuxie, you deserve to die!"

Mu Yongyuan let out a long roar, and the long sword in his hand suddenly transformed into thousands of sword shadows, and his momentum suddenly exploded.

"Senior brother, you have to be careful, this is the Tiankui Sword Technique!"

Jian Xing'er let out an exclamation, reminding Liu Wuxian to be careful with this set of swordsmanship.

"When I kill him, I will ravage you well!"

Mu Yongyuan is crazy, he is a disciple of the inner sect of the hall, with a high status, and he was forced to this position by the outer disciples, and it was humiliating to spread it.

The best thing to do is to kill them all, including Jian Xing'er.

"Shameless!"

Mu Yongyuan's words made Jian Xing'er raise her eyebrows, but she didn't expect Senior Brother Mu in her mind to be such a person.

A layer of geranium flowers appeared on the void, constantly blooming.

"It's kind of interesting!"

Liu Wuxian said secretly, and the evil blade was suddenly raised, and the fourth form of the life-killing sword technique.

All of a sudden!

These blooming sunflower divine flowers, deduced from the sharp sword, fell from the sky and intertwined into a heavenly net, wanting to seal Liu Wuxie.

"Liu Wuxie, you give me death!"

Mu Yongyuan let out a roar, and the Tianhua Divine Flower completely unfolded, and the piercing cold light evaporated one-third of the river's water source, one can imagine the extent of the power of this sword.

"It's ridiculous that you want to kill me just with your swordsmanship!"

Under the prying eyes of the ghost pupil technique, there is nothing to hide from any move.

The evil blade slashed down diagonally, and the Tianhua Divine Flowers that burst into the explosion exploded one after another, and after the Heavenly True Qi blessed the Demon Flame, it was even more powerful.

The most terrifying thing is his Gengjin power, which is indestructible, instantly disintegrating those swords around him.

Mu Yongyuan's expression became more and more solemn, and Liu Wuxie's combat power far exceeded his expectations.

"Qiang Qiang ......"

The ruthless sword gang, destroying the heavens and the earth, and the chilling knife intent, deduced the gods and Buddhas of the heavens, and their feet suddenly rose in the air, like a god descending.

"Break it for me!"

A suffocating explosion, centered on the two of them, swept out in all directions.

Then!

The two figures flew upside down together.

A mouthful of blood spurted out of Mu Yongyuan's mouth, the Divine Flower of the Celestial Flower was cracked, which hurt him greatly, Liu Wuxian's true qi not only contained toxins, but also a trace of demonic nature.

Invaded his body and made him very uncomfortable.

If this toxin and demonic nature are not removed in time, it will have a huge impact on his cultivation, and he will even stay in this realm for the rest of his life.

Shocked Mu Yongyuan, the matter is far from over.

Liu Wuxian was in the air, his body suddenly flipped over, and the surging power of the primeval stars filled the sky.

"Ancient Star Fist!"

There is no need to show mercy.

If you don't kill him today, you will find a way to get rid of yourself tomorrow.

As soon as the punch came out, Mu Yongyuan's face changed in shock, and he realized that something was wrong, he had already been hit hard, and he didn't dare to fight in love.

"Let's go!"

At the first time, Mu Yongyuan chose to flee instead of staying where he was and continuing the battle.

"I want to run!"

The Ancient Star Fist had already formed, like a terrifying wave, rolling towards Mu Yongyuan.

"Defense Charm!"

At the critical moment, Mu Yongyuan sacrificed a defensive talisman and spread it out in the air, blocking the Ancient Star Fist.

"Boom!"

The sky collapsed, the entire second underground floor was shaking, and countless demons raised their heads and looked over here.

A huge pit appeared on the ground, Mu Yongyuan spurted out a mouthful of old blood, did not dare to linger for a moment, and quickly fled into the distance.

Tiangang Quadruple wanted to escape, and the probability of Liu Wuxian catching up was very low.

Poor Kou Mo chased, Liu Wuxian stood in place, his face gloomy.

"Senior brother, are you alright?"

Jian Xing'er ran over quickly, with a look of concern.

"I'm fine!"

Mu Yongyuan had already fled far away, and it was too late to catch up, the most important thing in front of him was to complete the task and leave the underground demon realm.

"I didn't expect Senior Brother Mu to be such a person, I misjudged him before. ”

Jian Xing'er stomped her feet hard, and when she saw that Liu Wuxian was fine, she was relieved.

It's too late to clean up the battlefield, and sweep into the distance, and the battle here has attracted the attention of many demons.

In the past two days, the demons have been dispatched on a large scale to find a man and a woman.

Getting closer and closer to the core area of the second layer, the demons encountered gradually became stronger.

almost encountered a seventh-order demon clan, relying on the ghost pupil technique, Liu Wuxian avoided it in advance.

"Senior sister, where will the Xuanyin butterfly appear?"

If you continue to search aimlessly like this, you may not be able to find the whereabouts of the Xuanyin butterfly in three or five days.

Regarding the information about the Xuanyin Butterfly, Liu Wuxian didn't find it from the Library Pavilion, so he could only ask Jian Xing'er.

"Cold Yin Valley!"

Jian Xing'er said three words.

"Sounds so cold!"

Liu Wuxian shrunk his neck, this place must be full of infinite yin energy.

"That's right, this place is covered with yin qi all year round, and the Ice Pole Demon Ape also likes to appear here. ”

Jian Xing'er nodded, this place, ordinary people dare not go.

In addition to the demons, there is also a danger, the yin qi inside is pervasive, ordinary people can't resist the erosion of yin qi, and it is very likely that the yin qi will invade the body and die inside.

"Alright, let's go!"

Liu Wuxian didn't hesitate, he had already awakened the cold ice element, and the general cold qi had little impact on him.

Jian Xing'er hesitated, but still followed.

The second underground floor is very large, passing through several huge canyons, and a faint cold air permeates from a distance.

"Ahead is the Cold Yin Valley!"

Pointing to a pitch-black canyon in front of her, Jian Xing'er's face showed a hint of jealousy.

Before she met Liu Wuxie, she had been here once, and she almost died here, and this time, she obviously hadn't come out of the shadow of failure.

"What a strong cold breath!"

Before he stepped in, the Heavenly Swallowing Technique of the Desolation was put into operation, devouring the cold qi that was free in the air, and replenishing it to the Desolate World.

"Senior brother, we have to be careful, there are often demons here, and they like to lurk in the shadows. ”

Jian Xing'er drew her long sword, and the two walked almost side by side, and in case of danger, they could help each other.

nodded, and sacrificed the ghost pupil technique, a radius of thousands of meters, and it was in full view.

I couldn't perceive the changes of the sun and the moon, and I always thought it was late at night from the time I stepped into the ground, but in fact, more than ten days had passed.

Getting closer and closer to the Cold Yin Valley, Jian Xing'er was shivering from the cold, and she could only sacrifice her true qi to protect herself.

"Senior sister, you stay here, don't leave, the cold air inside is too strong, and it will be difficult for you to get out of it when you go in. ”

Liu Wuxian took out the formation flag and arranged a formation, so that Jian Xing'er would stay here and not let her set foot in the Cold Yin Valley.

"No, it's too dangerous for you to go alone!"

Jian Xing'er insisted on accompanying Liu Wuxian to go in to avoid accidents for him.

"Do what I say, these cold breaths don't have much pressure on me. ”

Regardless of whether Jian Xing'er agrees or not, trapping her in the formation, the demons outside can't get in, and she can't get out.

"Senior sister, the formation will be unraveled by itself in a day, if I haven't come out yet, you leave quickly, don't go in to find me. ”

After Liu Wuxian finished speaking, his body disappeared in place and entered the Cold Yin Valley.
