The scene was very chaotic for a while.

Xu Ye fell to the ground due to difficulty breathing, and the strange disciple who was running with him was suddenly stabbed in the mouth by a bamboo tube. With the brain extremely lacking oxygen and powerlessness, he also fell backwards in a daze.

With super high IQ and operation far beyond the reach of ordinary people, before being killed by the evil demon, these two brothers in distress jointly performed a "I kill myself" and firmly grasped their fate in their own hands, which was not easy.

Looking at the white bone demon behind them, it was actually several feet tall. Although only the head, chest and upper body with arms were left, the size was comparable to a small mountain.

When it propped itself up with its hands and swooped towards the two of them, the ground shook suddenly, and the snow flew everywhere, as if white jade had been shattered into thousands of tiny pieces, and the cold mist covered it with a layer of white visible to the naked eye.

This kind of evil demon has no mind, but is the resentment and death of the desolate land. Since all five senses have been lost, it can only judge the location of other creatures through breathing and hunt them down.

Rather than being called a "demon", it is more like a machine that never feels tired and only knows how to kill and destroy.

"This thing..."

He Zhizhou resisted the urge to complain about the "perpetual motion machine" and looked at the bone demon with great vigilance. The long sword at his waist made a weak humming sound: "To be able to make the two wolves come to this point, this thing must have a high level of cultivation."

He was right.

Ningning looked up and saw the huge skeleton roaring silently in the blizzard. The eye sockets that should have been empty were actually condensed with thick black air, like extremely dirty mud, which looked very abrupt against the white background.

It was the condensed death energy, and just a quick glance could make her feel stuffy.

"Its cultivation is probably at the early stage of Yuan Infant."

Seeing the Bone Demon getting closer and closer to Xu Ye and the others, Ning Ning knew that she couldn't wait any longer, and suddenly drew her sword: "I'll attract its attention, you take the opportunity to save people."

After she finished speaking, she urged the sword energy, and a white light flashed in her hand, and she attacked the Bone Demon without any reservation.

"Fiftieth floor."

He Xiaochen outside the Xuanjing stroked his non-existent beard: "From the 50th floor and beyond, the demons are all above the level of Yuan Infant. If Ning Ning goes hard... With her strength, although she has a high probability of winning, it must be a very miserable victory. If she is seriously injured in the first floor of the tower, the subsequent trials will be difficult."

"She is very smart and must know her limits."

Tianxianzi glanced at him thoughtfully, with a hint of ridicule in his eyes: "Master He, why did you come to Xuanxu Sword Sect without caring about the disciples of Liuming Mountain?"

He Xiaochen was hit in the heart and laughed foolishly: "I am not that, I care about the world! I definitely didn't come here specially to see - oh, Ningning is here!"

Tianxianzi turned his head quickly.

Ningning was very fast, and the sword light was completely swallowed up by the endless pure white snow, leaving only an extremely faint shadow.

She knew that the bone demon was not easy to deal with, so she used 70% of her strength at the beginning of the confrontation. The sword energy was like stars and rain, like a rainbow piercing the sun, and it hit the bones in an instant. The

sword energy and sword wind swept up the scattered ice chips and condensed into a thin snow wall in the air. This was an attack that gathered a thousand pounds of strength, but when it came into contact with the bone demon -

Ning Ning frowned slightly.

She finally understood why Xu Ye chose to flee in a panic when facing it.

Her sword energy was cold and sharp, and it slashed through the eerie white bones not far away, but only left a long mark half a finger deep.

The undead are not like living things. They have no sense of pain and no thoughts. No matter how serious the injuries are, they remain indifferent.

There is only one most feasible way to defeat it: smash the bone demon's hands, feet and neck one by one. If it can be disassembled like building blocks, perhaps the threat will be much smaller.

But this method does not work.

Not to mention that with their level of Jindan, it is difficult to seriously injure the Yuanying period evil demon. Even if it can be disassembled into several pieces like a Barbie doll...

the scene of the head, hands, feet and body jumping around together will seem even more weird than it is now. When

swinging the sword, Ningning's breath surged rapidly in an instant. The bone demon noticed it and shifted its attention from the previous prey to a pair of deep eyes.

...Ah, it seems very unhappy.

Rather than how to defeat it, the question that should be considered now seems to be "how to survive in its hands".

Ning Ning concentrated and took a step back, quickly looking at the scene beside her.

Not far away, He Zhizhou had already helped Xu Ye and the strange brother who had never met before to stand up, and made an OK gesture to her.

Xu Ye was lucky that he did not torture himself to the point of unconsciousness, but the unlucky guy who was chased with him was much worse off.

The two of them were already half dead due to suffocation due to lack of oxygen. When Xu Ye fell halfway, he suddenly spit out the bamboo tube in his mouth, causing the opponent's mouth to suffer a critical blow under the huge impact. He was in pain and choked, and almost died in the hands of his teammate.

That guy still hasn't woken up yet, so He Zhizhou had to carry him on his back, which was quite impressive.

As for the environmental conditions here -

"Ning Ning!"

He Zhizhou lowered his head and rummaged through the storage bag. Although he was often unreliable, he was serious sometimes. He heard that there might be undead demons in the Demon Refining Tower, so he bought treasures at the Luancheng Market: "I have a Turtle Breath Pill!"

When he said this, the Bone Demon just stretched out his arm and slapped forward.

Ning Ning reacted quickly and jumped back quickly. Although she was able to avoid the powerful palm strike, she squinted her eyes because of the splashing snow.

The moment she soared into the sky, she also saw the general situation here.

Just as she had seen before, this place and the other side of the single-plank bridge were both close to a cliff. The wide river was frozen, and even the waterfall was hanging in the air like a pancake.

Several peaks rose from the ground around, and the mountains were covered with thick snow. The green was eaten by silkworms and turned into a lonely white.

If they used the Turtle Breath Pill, although they could temporarily escape the pursuit of the Bone Demon, correspondingly, it would be difficult for them to defeat it.

If they tried their best now, there might be a chance.

"He Zhizhou!"

Ning Ning held the Star Mark Sword tightly and raised her voice: "I'll try it!"

"Try, try it?"

Ji Yunkai outside the mirror was lying on the table, his eyes wide open: "She doesn't want to challenge the Bone Demon alone, does she?"

"You don't want to challenge the Bone Demon alone, do you?"

He Zhizhou had already taken a Turtle Breath Pill, and heard this anxiously: "We are definitely not the opponent of this guy!"

Ning Ning just showed a smile that was similar to comfort, and made a sword flower.

Then she turned around and ran.

He Zhizhou: ???

She ran without hesitation. Because she didn't hold her breath and her sword energy leaked out, she became a living target for the Bone Demon.

The loud sound of the bones hitting the ground hit her eardrums again and again. Ning Ning was carefully observing the surrounding terrain, and suddenly saw a figure flashing beside her without any defense.

——He Zhizhou ran wildly beside her with the disciple on his back, and next to him was the pale-faced Xu Ye.

Seeing the surprise in Ning Ning's eyes, he snorted complacently: "Didn't expect it! We are strategic allies, and I will never let you take risks alone. Tell me the truth, what are you going to do?"

Xu Ye was tired like a dying old dog: "And, there's me!"

"This is only the first level of the tower. If you fight the Bone Demon head-on and consume your energy, you will suffer a great loss in the next trial."

Ning Ning raised her eyelashes and said in a deep voice: "Do you see those mountains? After we secure an area, we will act separately and use sword energy and fire talismans to shake the snow off the mountain."

He Zhizhou suddenly realized: "Do you want to create an avalanche artificially?"

He understood instantly.

Their own strength is limited. If they want to defeat the bone demon at the lowest cost, they must make the most of the power of the outside world.

And here, there is snow everywhere. Once all the snowflakes start to bravely break through the horizon, the impact caused... is absolutely beyond imagination.

Ning Ning seemed to want to say something, but the white bones chasing behind her were getting closer and closer. In a hurry, she could only nod: "Thank you."

"What's there to thank for!"

He Zhizhou raised his eyebrows and smiled, unsheathed his sword, took out a fire talisman from his arms, and stuck it in the center of the sword.

Although he was used to salt fish cutting water, after all, he had cultivation and the long sword had been forged and hammered countless times. As soon as he exerted his strength, he immediately set off layers of fire wind like huge waves.

Because he had taken the Turtle Breathing Pill, the Bone Demon did not pay attention to He Zhizhou and Xu Ye, but was chasing Ning Ning. However, she was the fastest among all the people, and the one and the demon always kept a fixed distance.

The other two, one on the left and one on the right, gathered their sword energy under the mountains, and the sword light was bright and the red light covered the sky.

The fire and wind were as powerful as a dragon, tearing through the white snow that covered the sky and the ground, and surged into the sky. In a moment, the mountainside shook violently, and after the deafening roar, the snow piles and melted snow water fell down.

The Bone Demon had no vision and hearing, so he didn't know what kind of changes had happened, but Ning Ning saw it clearly.

Before the snow roared down, she held her breath and dodged to the side. She

kept a distance from it so that she could use a living creature as bait.

Since the range of the avalanche had been defined before, when she brought the bone demon here, she led it to the center of the avalanche.

The snow was a dead thing without any breath, so the bone demon was destined to be unable to detect it.

"It's a good trick to use a dead thing to fight a dead thing."

Zhen Xiao leaned against the corner of the wall, looking at the scene of the bone demon buried in the snow in the black mirror, and frowned unconsciously: "But the evil thing is very powerful, and I don't know if this snow..."

Before he finished speaking, he heard a wild howl in the mirror.

Then, a huge hand with bony bones stretched out from the snow.

——Under such a violent impact, the bone demon was unscathed and struggled out of the snow pile!

"Is the body of this monster so strong?"

Ji Yunkai took a bite of the sweet cake, and his tone was emotional: "This method seems to have failed."

"Wait."

Tian Xianzi leaned forward a little, smiled with crooked eyes, and said: "Ningning moved again."

He Zhizhou and Xu Yi in the picture were shocked, but Ningning's expression remained unchanged, as if she had expected the current situation. After looking into the bone demon's dark eyes for a while, she smiled and raised her eyebrows.

As if it was a provocation that was bound to win.

Although the bone demon couldn't see her, the demonic energy became more intense because of what happened just now. He let out a hoarse roar from his throat and continued to rush towards her, waving his hands.

Ningning still acted as a living target and ran forward without looking back.

Tian Xianzi outside the mirror was stunned.

"So that's it!"

He grinned: "It's a river!"

Not far in front of Ningning was the wide, solidified river connected to the waterfall.

And when she ran forward, stepped over the ice and continued to move forward, the bone demon's hands would inevitably fall on the river.

It turned out that her plan was not to trigger an avalanche from the beginning.

In other words, the snow water falling from the avalanche was just a necessary catalyst in the plan.

The sword energy was mixed with fire symbols, and most of the snowflakes would melt into water and fall on the bone demon, instantly moistening the entire skeleton.

According to the law of friction, the magnitude of friction is closely related to the roughness of the contact surface.

The bone demon's body is supported entirely by its palms. Its joints are extremely smooth, and the lubricating effect of water greatly reduces friction. When it is on the ice, all it needs is a push.

Even if it is the smallest amount of force.

The huge white skeleton followed the girl onto the ice, and after a trance-like pause, it slid to the side uncontrollably.

Ningning turned around and stopped her hurried steps, stood by the river close to it, and swung the sword energy forward.

Bingo.

Home run!

The sword energy hit the Bone Demon's chest. The skeleton kept a confused look on its face and slid forward along the river, finally arriving at the waterfall on the cliff.

The Bone Demon's water slide also reached the end at this moment.

For the first time, a big puzzle appeared in its big eye sockets.

Then there was weightlessness, falling, and Newton closed his coffin carefully.

He Zhizhou looked at the beautiful curves and couldn't help but sigh: "This shot is really revealing."
