Since the Nine-Story Demon Tower is the sphere of influence of the Nine Yuan Dao Gate, there are naturally guards to maintain order.

Each pair of law enforcement teams is led by a monk from the Guiyuan Realm, even if there is a monk who wants to do something, the power of the high-level monk of the Nine Yuan Dao Sect does not dare to act rashly.

Yu Feifan avoided the old man's gaze, closed his eyes and seemed to be recuperating, in fact, Yu Feifan felt a vague aura that had been shooting unscrupulously on his body.

He didn't have to look at him to know that it was the green-haired old man.

"What is the origin of the other party, why is he staring at himself?" Yu Feifan thought secretly in his heart, his brows couldn't help frowning, he was not a cowardly person, in the face of such a provocation from the other party, Yu Feifan snorted coldly, a cold light flashed in his eyes, and quietly left the original place.

Sure enough, the moment Yu Feifan left, the green-haired old man raised the corners of his mouth and smiled fiercely with a distorted face, and then quietly followed Yu Feifan.

The location of the Nine-Story Demon Tower was originally the holy land of the Demon Clan, so some of the mountains around the Demon Tower and some plants were black, and even the sky above them looked extremely gray.

After Yu Feifan left the Nine-Story Demon Tower, he looked up at the dark red full moon in the sky, and even his expression became a little strange.

Almost the moment Yu Feifan stopped, he could already clearly feel the undisguised killing intent behind him.

Yu Feifan didn't want to provoke the green-haired old man at first, but if he didn't know where the other party's killing intent came from, he would probably be even more dangerous once he entered the magic tower.

The monks in the back were getting closer and closer, and Yu Feifan had already calculated his words in his heart. But in the next moment, Yu Feifan's face changed greatly, and his figure immediately moved back, taking advantage of the situation to hold the Hundred Ghost Sword in his hand.

At this point, where he left, a basin-sized fireball smashed a large hole into the ground.

"Huh!" a surprised voice came from the darkness, and slowly appeared.

"Guiyuan Realm cultivator, no, Guiyuan Realm Demon Cultivator!" After Yu Feifan saw the person who came, he found that the other party was actually a Guiyuan Realm Demon Cultivator.

"Isn't it too late to find out at this time?" the green-haired old man obviously didn't want to say anything more to Yu Feifan, a mere Innate Realm cultivator. The demonic energy on his body rolled and flashed with emerald flames, and a chain of emerald fire flew out of his body. He obviously wanted to subdue Yu Feifan with one move.

When Yu Feifan saw that the other party was a Returning Yuan Realm Demon Cultivator, an extremely strong dangerous emotion enveloped him. He knew how dangerous his situation was, and maybe in a moment he would be completely destroyed.

Yu Feifan had experienced several dangers since he had cultivated, but none of them were as dangerous as he was now. There was almost no room for manoeuvre, and the image of death even involuntarily appeared in his mind.

Even many years later, after Yu Feifan became a great cultivator, he still had a trace of palpitations in his heart every time he thought of tonight's scene.

Seeing the turquoise flames, Yu Feifan threw the Hundred Ghost Sword at the green-haired old man without hesitation. Then the palm of his left hand suddenly spread out, and the black lotus flower in the palm of his palm bloomed, and a huge ghost head with fiery red eyes and flames flew out of it.

As soon as the giant ghost appeared, he circled around Yu Feifan with a 'boom'. But when he saw the green flame, the ghost head actually flinched.

Where can Yu Feifan take care of these, and his spiritual power is rapidly urging. The ghost head opened his mouth, and there was madness in his eyes, and he suddenly pounced on the turquoise flames. A large mouth swallowed the turquoise flame into his belly.

The ghost head's cultivation was simply not enough to devour the emerald flames, and as soon as the flames were swallowed by him, the ghost head immediately began to howl and deform, and his whole body was covered by the red and green flames alternately, and it seemed that it would explode at any time.

"It's just a ghost who wants to devour my 'poisonous heart fire', it's beyond my strength. The green-haired old man sneered, and was about to activate the spell to completely burst the ghost head.

The strange thing is that the giant ghost was forcibly recalled and sealed by the black lotus in Yu Feifan's hand, Yu Feifan knew very well that once the other party succeeded, he would have no way to resist the other party's so-called 'poisonous heart fire'.

As soon as the giant ghost and the devouring flame were sealed by Yu Feifan, a burning sensation immediately came from his left hand, fortunately, the black lotus flower given to him by Nanhuazi was a little strange, and it really sealed the flame together with the giant ghost.

"How dare you seal the old man's 'poisonous heart fire'!" Green Flame was furious. As soon as his hands were closed, a turquoise flying knife appeared in the upper and lower palms, and the flying knife rotated rapidly, slashing towards Yu Feifan in an instant.

Almost at the moment when the flying knife was triggered, Yu Feifan secretly screamed that it was not good, and the whole person subconsciously planted backwards, and then took advantage of the situation to roll aside.

"It's so dangerous!" Yu Feifan looked at the black blood coming out of his right shoulder and secretly called it a fluke.

Yu Feifan jumped up from the ground and immediately drew the Heavenly Demon Sword in his hand, relying on the other party's Yuan Realm cultivation to cultivate himself, there was no way to escape. Even so, Yu Feifan will never be caught.

As for the Hundred Ghost Sword that was thrown, the other party was scattered with just one finger, and the aura fell.

The Heavenly Demon Sword was withdrawn, and Yu Feifan poured the aura of his whole body into it.

"Seniors help me!" Yu Feifan secretly communicated with the demon spirit, since he had already made a move, he had to kill the other party with one blow, so he had to use the demon spirit to summon people. "The power of the demon spirit is not satisfied, although doing so may make the demon spirit that has just awakened fall asleep again.

"Hmph, you kid will make a call for grace, the demon spirit snorted coldly, but he had to help Yu Feifan.

The lotus seal on the Heavenly Demon Sword used to seal the demon spirit emitted a dazzling white light, the sword body of the Heavenly Demon Sword trembled, and Yu Feifan felt an extremely strong energy coming from the sword body.

"Slash!" Yu Feifan swung the Heavenly Demon Sword in the air, and a white crescent-shaped blade wrapped in black gas slashed towards the green flame.

With Green Flame's cultivation, he could have dodged Yu Feifan's attack, but he didn't take Yu Feifan in his eyes, and no one would have thought that a mere Innate Realm cultivator could launch such an amazing attack.

Green Flame looked at the sword blade above his head and was suddenly startled in his heart, his eyes became solemn, he actually felt a dangerous aura from the blade. Hurriedly pointed to the flying knife that was hovering above his head with his hand, and the flying knife stretched out and greeted it with a knife.

After Yu Feifan's blow, his face was pale and he landed not far away, his eyes shining with a strange light, staring at the swords in the air.

"How is that possible?" exclaimed Greenflame.

His throwing knife had been knocked away, and the crescent-shaped blade was already close at hand.

Fortunately, Green Flame was not an ordinary monk, and immediately sacrificed a small green tower from his body to cover his whole body. The blade of the sword struck the tower, only shaking the small tower a few times.
