Xuan Ku and Fu Mozi glanced at each other, not knowing what they were thinking, in short, neither of them moved, maybe because the special marks placed on Yu Feifan's body did not disappear. Yu Feifan stood in the thunder pool, feeling the power of thunder and lightning outside him, and he didn't continue to take one more step forward. At this time, he closed his eyes and looked inward, and his eyebrows couldn't help frowning slightly.

"Found it!" he opened his eyes with a hint of joy. If someone can see through Yu Feifan's dantian, they will find that in the Huayuan Ding, there are two clusters of light, one black and one red.

These two rays of light were the ones that Xuan Ku and Fu Mozi hit into Yu Feifan's body, and the mark of Xuan Ku was fortunately just an ordinary mark, but the black qi imposed by Fu Mozi was a mysterious spell, and Yu Feifan couldn't detect its effect.

"Master, do you want me to turn them to ashes? Xiao Yuanzi's voice came from within his body.

Yu Feifan's eyes flickered, and he finally shook his head and confirmed again: "How long can you get rid of them?"

"I'm known as Huayuan, although I don't have an ontology, but it's only a matter of a moment to transform these two markers. Xiao Yuanzi's voice was full of pride.

Yu Feifan nodded, not in a hurry to dissolve them.

Although there was a thunder and lightning barrier, Yu Feifan could still see the skeleton of the demon dragon that was more than ten steps away from him. He didn't rush to collect the bones, but slowly took out the Heavenly Demon Sword from the storage bag, the body of the sword trembled slightly, and he looked extremely excited.

"It seems that this demon dragon is not simple, even the Heavenly Demon Sword is extremely excited. The demon spirit emerged from the Heavenly Demon Sword, and his voice was full of solemnity.

Yu Feifan pondered for a while, even if there was any change in this demon dragon, he had to explore one or two, otherwise the two outside would not let him go. Thinking of this, the demonic energy in his left hand flashed, and the Green Devil Tower was sacrificed above his head, and he held the Heavenly Demon Sword in his right hand and walked towards the demon dragon step by step.

Outside the pit, Xuan Ying and Feng Li were not there, but at the top of the thundercloud mine, at this time, there was a cyan light curtain in the middle of the two, and the light curtain showed every move of the thunder pool below, but the picture was blocked the moment Yu Feifan entered the thunder pool.

"What's going on?" Fengli wondered.

Although Xuan Ying did not speak, his face was also extremely solemn. After a long time, he said meaningfully: "It seems that there is an abnormality below, let's prepare early." ”

Although Feng Li hesitated a little, he finally nodded with a serious face.

Yu Feifan approached the demon dragon skeleton step by step, what he didn't know was that the eyes of the skeleton that seemed to have no signs of life for a long time actually flashed with a faint red light. Even the desiccated corpse shook slightly.

It's a pity that Yu Feifan didn't notice all this, he still cautiously approached the demon dragon bones step by step.

The Heavenly Demon Sword in his hand trembled even more, which made Yu Feifan's uneasiness increase a little. He worked hard to control the Heavenly Demon Sword in his hand, and the mana in his whole body was running so that he could use Huayuan Ding to escape from this place at any time.

Getting closer and closer to the magic dragon, Yu Feifan could even see the dragon horn lines on the dragon's head. At this moment, Yu Feifan obviously found that the faucet was shaking.

"Not good!" Yu Feifan secretly screamed, but it was already too late. The huge skeleton of the demon spirit, which had been coiled, actually moved all of a sudden, and the demonic energy on the skeleton seemed to have instantly turned into a real demon dragon.

Seeing this, Yu Feifan immediately covered the Blue Devil Pagoda all over his body, and the Heavenly Demon Sword in his hand was about to slash at the demon dragon. It's a pity that the change in the next moment caught Yu Feifan off guard.

The demon dragon let out a long groan, and his body actually flew up, as if the demon dragon had been resurrected, and he swallowed Yu Feifan into his body in one fell swoop.

This sudden change suddenly made the entire thunder pool change, and the huge thunderstorm power made the faces of Xuan Ku and Fu Mozi on the side shocked, and they retreated one after another to release the talisman. Xuan Ku released the 'Ring of Fire', and Fu Mozi sacrificed the bowl and bowl on the top of his head.

After the huge thunderstorm, Fu Mozi and Xuan Ku immediately flew close to the thunder pool, although they looked a little embarrassed at the moment, their expressions were very anxious.

There were no demon dragon bones in the thunder pool, and even Yu Feifan disappeared. Under such a thunderstorm, a mere Returning Yuan Realm monk would not be able to resist it no matter what, I am afraid that it has already turned into ashes at this time.

"I'm really careless!" Xuanku's face was gloomy as water, and his heart was full of remorse. Fu Mozi's face was also ugly, and the power of thunder and lightning in the thunder pool at this time had weakened a lot because of the thunderstorm.

The two soon found a pitch-black cave in the middle of the thunder pool, and the cave was full of demonic energy, and it turned out to be a magic eye.

"The Demon Eye is obscured by that Demon Dragon Skeleton here, is there anything strange about that Demon Dragon Skeleton?" asked Xuan Ku to Fu Mozi on the side. At this time, the look of anxiety on his face was much less, because in the moment just now, he suddenly felt the mark in Yu Feifan's body.

"It's really a bit weird, I didn't expect there to be a magic eye here that is rare in the Demon Gate, that demon dragon skeleton should be affected by the demonic energy, and the spirituality has been regenerated after countless years. After all, Fu Mozi is a demon monk, and he quickly made his own judgment. His expression also eased a lot, and he also communicated the spell left in Yu Feifan's body.

"In that case, how about we go down and explore this magic eye together?" Xuan Ku suggested.

"Although you and I are cultivators in the Evil Realm, our Demon Eyes are full of 'Bone-Destroying Wind', and even you and I can't last long in it. Besides, that magic dragon is very weird, and you need to be cautious. ”

"Do you want to give up that demon dragon bone, even if the bone has some spirituality after being nourished by demonic energy, it is just a trace of spirituality, are you and I afraid that it will not work. Xuan Ku's face sank, and he said with some dissatisfaction.

"Hehe, why should Daoyou be like this. I believe that Daoyou should also know that the kid has not fallen, I am afraid that he entered the demon eye with that demon dragon. Fu Mozi said with a smile.

"So what?" Xuan Ku did not deny.

"Even that demon dragon can't hide in the demon eye for a long time, as long as you and I wait quietly, it will come out again sooner or later. Maybe that kid will surprise us a bit. Fu Mozi expressed his opinion.

Xuan Ku was silent for a while when he heard this, he had the heart to go down to investigate, but if Fu Mozi was unwilling, he would not go down alone.

Although Yu Feifan was swallowed by the demon dragon in his belly, he did not panic, the two protective purple bamboo ignition and golden spirit cover outside his body had been exhausted because of the thunderstorm, and only the Blue Devil Pagoda was suspended above his head to protect him inside.

"Is this the body of the demon dragon?" Yu Feifan said secretly in his heart, at this time, he was deep in a gray space, and the surrounding walls were actually composed of bones, and the bones exuded demonic energy, about the size of a room.

Yu Feifan tried to stand the Heavenly Demon Sword on top of the bones around him, and the strange thing was that there was a force on the bones that immediately bounced him back.

"Quack, it turned out to be the Heavenly Demon Sword!I didn't expect the old man to have such a great opportunity!" A terrifying voice suddenly sounded in the empty space.

Yu Feifan immediately searched with his spiritual sense, but he couldn't find anyone.

"You don't have to work in vain, it's a joke that you still want to live since it's in my womb. But you have some meaning, you are obviously a human race, but you have demonic skills, and you also have the first artifact of the demon race, the Heavenly Demon Sword. The demon dragon seemed to have not spoken for a long time, and continued, "But none of this has anything to do with you, no matter how much chance you have, once you are killed, it is just a wedding dress for others." ”

"Make a wedding dress," Yu Feifan's heart moved, although this statement was a bit cruel, it was also a fact in the cultivation world.

Although Yu Feifan's spiritual sense could not lock the person who spoke, his heart was slightly relieved, since this person refused to show up, it showed that the other party must have cared about it. "If you swallowed me up here, why did your Excellency hide your head and tail? Yu Feifan's voice was loud, and at the same time, he put the Heavenly Demon Sword in front of him.

"What a bold man, even a single human race dares to be presumptuous in front of the deity!" The demon dragon seemed to be really angry, and the surrounding demon bones and demonic qi were tumbling, and a viscous liquid immediately approached Yu Feifan.

"Zizi!" As soon as the demonic qi touched the outermost aura cover, it immediately made a sizzling sound, and this liquid actually had an extremely powerful corrosive effect.

Yu Feifan didn't dare to slack off, and the Blue Devil Tower above his head was urged by the demonic qi to grow bigger immediately. Directly cover Yu Feifan in the tower. The Blue Devil Tower was obtained from Bi Yan's hands, and Yu Feifan actually didn't know its driving method, and at this time, it was just driven by demonic qi.

The Blue Devil Tower is an 'ancient magic weapon', even if the urging method is wrong, the power is already incomparable to that of ordinary magic weapons.
