The moment the black demon snake swept over with its giant tail, Li Nanxing and Mo Qingxuan glanced at each other, the former did not make any resistance, and the latter waved the Suxin Sword and quickly slashed towards the tail of the giant snake.

The sword technique practiced by Mo Qingxuan is called 'Qinglian Sword Codex', also known as Qinglian Sword Technique, which is divided into ten realms, namely hitting water, chasing dust, no trace, wind, floating, hitting the moon, Tonghui, avoiding the sun, shadowless, and shocking rainbow.

She has cultivated for many years, but she has only cultivated to the realm of the sixth layer of "Blue Lotus Hitting the Moon", and it is already the limit.

The moment the cyan sword touched the tail of the black demon snake, it made a loud earth-shattering sound, and the powerful aftermath almost shook Mo Qingxuan's body out.

Suddenly, the surrounding rocks were scattered, with a terrifying momentum, which deeply shook the world.

Mo Qingxuan didn't know if relying on the power of the Qinglian Sword Technique could cause harm to the Black Demon Snake, but as long as she could drag this big snake down, then she would be satisfied.

Hiss!

The Black Devil Serpent let out a loud roar as it spat out red letters.

It turned out that Mo Qingxuan's sword just now directly cut off the tail of the black demon snake, and the severe pain made it painful.

When Li Nanxing saw it, he was horrified in his heart, and was about to slap Mo Qingxuan's ass, only to see that the black demon snake chased after them again, and the speed was simply amazing.

"Oh no, the serpent is chasing after you!"

Li Nanxing hurriedly sped up, but unfortunately he was still too slow after all, and he was caught up by the Black Devil Snake after not running a few steps.

Mo Qingxuan originally planned to step forward to protect Li Nanxing, but he didn't want to be blocked by the black demon snake with his tail.

At the same time, the Black Devil Snake moved its head to Li Nanxing's side and slowly opened its bloody mouth, as if it wanted to swallow him in one gulp.

"Whew..."

Li Nanxing saw that even though he was anxious, he didn't feel flustered because of this, he knew that the more he was at this time, the more he had to stay calm, otherwise it might really be over.

At the moment when the Black Demon Snake was about to swallow Li Nanxing in one gulp, the latter forcibly endured the disgusting fishy smell and hurriedly resisted with the Yellow Dragon Shield in his hand.

Bang!

Li Nanxing was glad that he was not eaten by the giant snake, but at the same time, he knew that it was impossible to last too long with his ability, after all, the disparity in strength between the two was really huge.

"Hold on, I'll go over and save you."

Cutting off one of the tails of the Black Demon Snake again, Mo Qingxuan swung the Suxin Sword and began to slash towards the top of the big snake's head.

This seemingly careless sword actually hides great power, but Mo Qingxuan himself doesn't know it.

Forcing Li Nanxing to the corner, the Black Demon Snake no longer chose to chase, but turned around and spit out a cloud of black mist at Mo Qingxuan.

This black mist is somewhat peculiar, in addition to the strong fishy smell, it can also block some powerful attacks.

Therefore, when Mo Qingxuan's sword light came into contact with that black mist, it was completely blocked.

The collision between the black mist and the cyan sword light did not last long, and with the dissipation of the black mist and the gradual weakening of the cyan sword, it slowly came to an end.

Mo Qingxuan was shocked, that sword condensed all her strength, she thought that she could cut off the head of the black demon snake, but she didn't want to be dissolved by a cloud of mist.

This made Mo Qingxuan feel a little frustrated, and at the same time, she also understood that relying on her imperfect Qinglian sword technique, it seemed that she could not hit the big snake in front of her hard, so she had no choice but to find another way.

"If you don't want to die, leave quickly, or find a hidden place to hide." After Mo Qingxuan finished speaking, he stopped paying attention to Li Nanxing, and then took out something like a nail from his body.

This thing is called 'Jimu Thorn', also called Jimu Heart Nail, about five inches long, the color is blue, it is a high-grade magic weapon, from the hand of Ming Xiao Jumu Qinghan.

Mo Qingxuan had only been getting this thing for two months, and she had never really used it, so she didn't know much about the power of the Extreme Wood Thorn, and now she could borrow the body of the Black Demon Snake to try it out.

Throwing the Polar Wood Thorn into the air, Mo Qingxuan shouted softly at the Black Demon Snake, and then controlled the Polar Wood Thorn and stabbed it towards the heart of the big snake.

As if sensing the power of the Extreme Wood Thorn, the Black Demon Snake's giant tail flicked, and hurriedly flashed towards another hole, while a cloud of black mist spit out from its mouth again.

Li Nanxing hid in the corner, secretly observing the process of the battle.

Originally, the moment Mo Qingxuan took out the Extreme Wood Thorn, he guessed that the power of this thing should not be weak, but he didn't expect that it would completely deter the Black Demon Snake.

Just when Li Nanxing felt relaxed about this, he was suddenly almost fainted by a strong fishy smell.

"Oh no, it's poison gas!" Li Nanxing hurriedly covered his nose with his clothes to prevent excessive inhalation of poisonous gas, which would cause physical discomfort.

"Just hide obediently, don't let me distract yourself to save you."

After Mo Qingxuan finished speaking, he tore off a piece of cloth from his body, tied it to his face, and entered the hole where the black demon snake was alone.

After a while, the black snake rushed out again.

While Mo Qingxuan was manipulating the Extreme Wood Thorn, she was chasing after the Black Demon Snake, but she was actually looking for an opportunity to pierce the Black Demon Snake's heart in one fell swoop.

After the black demon snake fled for a while, it finally chose to stop next to the wall hole on the left, and its two eyes like lanterns showed a hint of cold light.

At a certain moment, a green light appeared on the black demon snake's body, giving people a very strange feeling.

And with the disappearance of the green light, all the injuries on the black demon snake's body actually disappeared, and even the two tails that had been cut off by Mo Qingxuan before were also regrown at this moment.

When Mo Qingxuan saw it, she frowned unconsciously, she faintly felt that the sense of oppression given to her by the Black Demon Snake at this time was obviously much stronger than before.

The sudden appearance of the scene surprised Li Nanxing, who was hiding in the corner, and then he moved his gaze to Mo Qingxuan, his dark eyes were full of worry.

At this time, Mo Qingxuan turned around, her eyes stayed on Li Nanxing's face for a moment, and said with a smile: "It's almost over!" ”

Li Nanxing didn't understand the meaning of her words, and was about to ask, only to see Mo Qing take out a delicate jade box from the storage bag.

Looking at the jade box in her hand, Mo Qingxuan's face was solemn, this thing was given to her when Fang Yan went out to practice, saying that when she encountered danger, she only needed to urge this thing to save her life.

After such a long time, she has always followed Ruan Xingxian and has never encountered danger, so she has always carried this thing with her.

Mo Qingxuan was a little reluctant to call the jade box, and a golden talisman was revealed, on which was a picture of a divine fire flying crow, listening to Ruan Xingxian say, this talisman is not an ordinary talisman, but a powerful talisman treasure.

Mo Qingxuan had heard of the name of the talisman for a long time, but she had never seen anyone use it, and the reason why she took out the 'Divine Fire Talisman' at this moment was to use the power of the fire talisman to destroy the black demon snake, and secondly, to say goodbye to the past and start a new life.

"It's... Could this be the legendary rune treasure? Just as Mo Qingxuan was sacrificing the Divine Fire Talisman, Li Nanxing felt that the entire cave was suddenly enveloped in a hot air.

With the urging of the talisman, I saw that the divine fire crow pattern on it actually jumped, and with the gradual strengthening of the red light, the movements of the firebird on it were also the lighter and more flexible as before.

Eventually, the Divine Fire Talisman revealed its true prototype, which was actually a red bird.

"Go ahead!" When the two words fell, Mo Qingxuan flicked his fingers on the red bird, and the fiery red bird immediately flew out of Mo Qingxuan's palm and slowly flew forward.

After a while, I saw this red bird, which was only the size of a palm, let out a crisp chirp, and then turned into a flame giant bird the size of a zhang, and with a flick of its two wings, it quickly pounced on the black demon snake.

The moment the Flame Giant Bird pounced on the Black Demon Serpent, a monstrous flame emerged from its body, making the entire cave gorgeous and colorful.

Li Nanxing was surprised to see it on the side, and his intuition told him that this should not be an ordinary flame.

And he vaguely saw that the moment the black demon snake was surrounded by flames, it let out a tearing roar, and then flicked its giant tail and fled desperately to the side.

The Black Viper moved fast, but unfortunately, the Flame Giant Bird had already cut off all of its vitality as it pounced on its body.

In just a few moments, the Black Devil Serpent turned into a fiery snake several feet long, and was finally burned to ashes by the flames.

"It's finally over......" Seeing the Black Demon Snake burned to ashes, Mo Qingxuan's whole person relaxed.

At this time, Li Nanxing came out of the corner, hugged Mo Qingxuan, and said with concern: "Are you okay?" ”

"It's okay, thanks to this rune treasure given to me by my senior brother, otherwise if you want to defeat the Black Demon Snake, I'm afraid it's not that simple."

"Now that it's over, let's go back." After speaking, Li Nanxing grabbed Mo Qingxuan's hand and walked outside quickly.
