As long as I make this oath, I will be completely subject to you, and I will never betray it!"

The demon dragon said anxiously.

Lin Xi's eyes narrowed slightly, revealing a thoughtful look. Then he nodded:

"You try, if you dare to play any tricks, you will still die!"

"No, it won't! You have the dragon's breath of Lord Rumoult, I can't fool you! And I can't escape your pursuit!"

The demon dragon said urgently.

The demon dragon didn't wait for Lin Xi to speak, and immediately turned around, and the dragon body, which was as black as a mountain, prostrate in front of Lin Xi, put on a surrendering posture:

"I, the Demon Dragon Motu, swear by the soul of the Demon Dragon Clan, that I am willing to surrender to the human race in front of me, and I will serve him for the rest of my life. Honor him as Lord!"

As he spoke, the Demon Dragon Motu opened his mouth, and a huge fireball burning with the black flames of hell immediately erupted from his mouth.

This is the Inner Dan of the Demon Dragon, and it is also the most precious thing of the Demon Dragon Clan.

"Roar!"

In the depths of the void, a faint soul howl sounded, and I saw that on this huge demon dragon Neidan, black flames rolled, and soon a faint, palm-sized demon dragon phantom appeared.

This small demon dragon phantom rose up, crossed an afterimage, and slowly submerged into Lin Xi's mind and merged into Lin Xi's soul.

Lin Xi immediately felt that the demon dragon phantom in front of him was the epitome of Motu's soul. With just one thought, he can tear the Hell Demon Dragon in front of him to pieces and destroy it.

Not only that, when this demon dragon miniature entered his mind, Lin Xi also felt a trace of strange energy, which poured into his mind at the same time. In an instant, the magma layer in front of me suddenly became "clear", as if it had become transparent.

Lin Xi could even "see" twenty zhang away, a nail-sized salamander crawling in front of him.

"This is the vision of the magic dragon! If you accept the allegiance of our demon dragon, you will have the vision of our demon dragon clan. Even if you are in the lava, you can clearly see what is around you. ”

Motu's voice sounded in Lin Xi's mind.

"I see.

Lin Xi's eyes opened and looked around. He could clearly see the screaming and whistling hordes of hell around him, and the bright red magma currents around him.

It's an amazing feeling!

At the same moment, Lin Xi felt Motu in front of him, pious and humble thoughts.

Motu is a demon dragon who is not willing to surrender to other creatures easily. Even the Demon Great Lord, who was the tenth level of Qi Refining, would not be able to make the demon subdue. But the strange thing is that Lin Xi felt that the demon dragon in front of him was very loyal to him. Even a slave to a master cannot do so.

Motu bowed his huge and noble head, his heart filled with awe and loyalty.

Lin Xi didn't know that when he opened his eyes, one eye was the black vertical pupil of the Hell Demon Dragon. And the other eye is the golden vertical pupil of the primeval true dragon, the kind of breath that travels through time and space, ancient and vast, sacred and noble, and towers over all living things, almost instantly conquered Motu!

This unruly Hell Demon Dragon has a deep sense of awe. In front of a human, he bowed his proud head.

"Okay, this is the Qi Enhancement Pill. You swallow it. But take a good rest, and then we'll go. ”

Lin Xi threw it casually, and a ball of true qi wrapped a pill of Danluo and sent it to Motu. This was given to Lin Xi by the Qinglian Holy Maiden, and it was the seventh qi enhancement pill for qi refining. However, Lin Xi was useless, kept it until now, and casually gave it to the demon dragon in front of him who had just been subdued.

The elixirs in the Immortal Dao are all extremely pure energy, without task impurities. Even the Demon Dragon can be swallowed.

With a big mouth, Motu swallowed the pill the size of a human fingernail.

The Demon Dragon's body was extremely strong, and a pill of Immortal Dao Medicine was far from enough to restore its full strength, but it was enough to restore some of its energy.

"Huh?"

When Lin Xi saw the appearance of the Hell Demon Dragon, he didn't say a word, condensed the Burning Yang True Qi, gathered a stream of pure energy, and immediately entered the Hell Demon Dragon's body.

"Whew!"

Motu was supported by this energy, and immediately shouted excitedly. The Hell Demon Dragon was originally a fire-attribute monster, and when he obtained this fire element, whose quality was even higher than that of the Hell Flame, it was like a heart booster, and he was very excited. I just feel that my whole body is full of strength.

"Hosts, I feel much better. Now, let's go hunt the other dragons!"

Motu said excitedly.

It was originally beaten half to death by Lin Xi, but at this moment, it suddenly became vigorous, and its two eyes were shining as if they were full of infinite power.

"Okay! let's go hunt the other dragons!"

Lin Xi laughed, and a snow-white light burst out of his eyes.

With a native Hell Demon Dragon leading the way, it is simply like a tiger with wings. One person and one dragon working together, it's simply not too easy.

"Let's go!"

As soon as the voice fell, Lin Xi and Motu immediately shot out. Swim towards another Hell Dragon's lair.

"Motu, are you crazy? You actually entered my realm of human beings! Are you challenging me?"

Under the rolling magma layer, a black dragon crouched at the bottom, its eyes narrowed slightly, shooting a dangerous light, looking at the black demon dragon swimming in the other side.

"Haha, Moss, you're thinking too much. I have come to deliver something to you on the orders of Lord Rumoult. ”

Motu laughed and exchanged in the manner of a demon dragon.

"Are you kidding? Not long ago, the High Lord of Gassem appeared in the sea of magma. Rumoult failed to challenge him and has now been killed by Gassem. First, you said that Rumoult sent you? Are you dead, just like him?"

There was a hint of mockery in Mousse's eyes.

"Hehe, if Lord Rumoult sent me here, you can see if you can see. Maybe the ghost of Lord Rumoult sent me. ”

Motu smiled darkly, and suddenly opened his mouth.

"Huh?"

The Demon Dragon Mosse's eyes blinked, and it felt that there really seemed to be something in Rumoult's mouth, and immediately wanted to look at it.

"Whew!"

The surging and majestic flames, molten gold and iron, mighty, like rivers and seas, erupted from Motu's mouth. In an instant, like red-hot iron juice, it was splashed on the head of the demon dragon Mousse.

"Ahh

This move came suddenly, and the demon dragon Mosse immediately screamed miserably, and her whole body rolled in pain.

Its entire skull burned, and even the scales could not stop it.

The Hell Dragon is not afraid of flames, and the flames of the Demon Dragon Clan can burn a great demon to death, but it is ineffective against the Hell Dragon itself. Moss never thought that Motu, as a hell dragon, was not spewing black flames, and this kind of flame could actually burn herself.

"Motu, don't do it yet!"

As soon as Lin Xi succeeded, he immediately jumped out of Motu's mouth. At the same time, he smashed his hands, and the majestic true qi swept into the sky, overwhelming the mountains and seas, and bombarded the demon dragon in front of him fiercely.

"Roar!"

Motu let out a howl of excitement and bit Mosse's body hard, and at the same time, two pitch-black dragon claws, taking advantage of the burning eyes of the Hell Demon Dragon, set off a surging demonic energy and smashed it its body.

Bang!

The heavens and the earth cracked, and the strong true qi and power blew up the magma ocean within a radius of hundreds of zhang. The Hell Demon Dragon was attacked by a man and a dragon, and he was shocked and angry, and he howled in pain:

"Motu, you are so despicable that you have joined forces with humans!!"

A fierce demonic aura, like a tidal wave, exploded wildly from its body. The strong body of the Hell Demon Dragon, flipped wildly, trying to get rid of the entanglement of this man and a dragon.

However, Lin Xi's blow was taken by surprise and had been planned for a long time, how could he let him run away.

At the moment when he hissed, there was a flash of shock, and a cold light slammed into the open mouth of the demon dragon.

This blow is the best timing, and the attack is even more tricky!

As soon as Lin Xi succeeded, he was calm and calm, and immediately controlled the magic sword, stirring vigorously in the body of the demon dragon mousse.

The Hell Demon Dragon's body is so strong that its muscles can't even cut through the magic sword. But inside the body, it is far less powerful.

"Howl!

Mo Long howled in pain, and immediately messed up. Lin Xi's sword burned even more than the previous Blazing Sun True Qi, which made it panic even more.

Inside the body is the Hell Dragon's biggest and deadliest weakness.

Lin Xi manipulated the magic sword, and the moment it shot into her body, it was doomed to the fate of this hell dragon.

Lin Xi and Motu are one person and one dragon, and it is not too easy to unite to deal with a Hell Demon Dragon of the Qi Immortal Stage!

The battle lasted for a short time, and when Lin Xi sacrificed the "Golden Giant Ding" and smashed it heavily on the head of the Hell Demon Dragon, the battle ended immediately.

The bottom of the lava was a mess, and many dragon scales were scattered among the magma. Mousse's massive black dragon body lay motionless on the ground.

"Master, this is already the third ......"

Motu, the Hell Demon Dragon, prostrate on the ground, said respectfully.

"Hmm. ”

Lin Xi nodded and stepped forward. A palm pressed against the body of the Hell Demon Dragon's mountain. At the same time, unleash the "Domination of the World" to absorb the power of the Hell Demon Dragon's physical body.

"Buzz! one by one"

The energy of the Hell Demon Dragon, like a river, poured into Lin Xi's body.

This way of absorbing the essence of fierce beasts, Lin Xi is not the first time to use it. I saw that the huge body of the Hell Demon Dragon, like a punctured ball, quickly dried up.

And the true qi in Lin Xi's body is getting stronger and stronger. Along the way, he had absorbed all the energy of the two Hell Demon Dragons, and this was already the third.

Lin Xi's body became stronger and stronger, and his true qi became more and more majestic, and in the end, he actually made a roaring sound like a magma torrent.

"Boom!"

When the body of the Hell Demon Dragon was about to completely dry up, in the middle of Lin Xi's dantian, a golden "divine pool" tattooed with strange talismans took shape......
