The Heavenly Demon Monarch felt that Shen Xiang was not easy to deal with, and Shen Xiang still had the same strength as a dragon, he didn't know how Shen Xiang, a human being, cultivated it. The power aura fused with the dragon power and the demon suppression holy power made him very uncomfortable, and it also carried a kind of fire that he hated the most, and he didn't know what kind of fire soul Shen Xiang mastered, which made him feel inexplicable fear. And the three kinds of power are fused together, and the power is even greater, not to mention the addition of the Blue Dragon Demon Slayer Knife.

Shen Xiang also felt that the Heavenly Demon Monarch was not easy to deal with, he was really fighting with the Heavenly Demon Monarch this time, and the Blue Dragon Demon Slayer Knife was sending him more and more information, he already knew that the Heavenly Demon Monarch had no body, just an evil demon soul supporting it, similar to something like a divine soul.

The Heavenly Demon Monarch relied on his powerful demon soul to devour his powerful power, and then turned into various forms! When the Heavenly Demon Monarch was at his peak, he actually passed a hundred moves with the Ten Heavens Emperor, and was killed by the Ten Heavens Emperor after a hundred moves.

Tens of thousands of years passed, and the Heavenly Demon Monarch was reborn with the help of a remnant wisp of demonic soul, and then regained his cohesion.

Shen Xiang waved the divine sword and slashed wildly towards the Heavenly Demon King, this was what the Ten Heavenly Emperor did back then, so he planned to try, although the effect was not very good, but it could temporarily suppress the Heavenly Demon King.

"It doesn't work, this guy is in the state of a demon soul, it's useless for you to use brute force, because there is a gap between you and his strength, you just rely on the demon suppression holy power to restrain the demons!" Long Xueyi said.

Shen Xiang naturally understood this, he felt that if he wanted to defeat the Heavenly Demon King, he had to use the Divine Killing Technique in the Heaven and Earth Killing Technique!

But he hasn't mastered it yet, and he can't use it at all.

Five pairs of long arms suddenly appeared behind the Heavenly Demon Monarch, stretching out towards Shen Xiang, each arm had a long knife made of black gas, and while stretching out, he waved it wildly towards Shen Xiang, although those knives were made of black gas, but Shen Xiang could feel the sharpness of the blade, and while slashing over, it left Dao residues in the void.

The Green Dragon Demon Slayer Knife buzzed and reverberate, like a dragon's groan, and Shen Xiang waved the vibrating divine knife to meet the black knives of the Heavenly Demon King.

The ten arms of the Heavenly Demon Monarch were very flexible, and they could suddenly disappear and suddenly appear again, Shen Xiang swung his sword to resist, it was only in vain, the moment he swung the knife, he could sense that there were several vital points on his body that were locked by a few cold forces.

It turned out that six knives suddenly stabbed over, and the ten arms of the Heavenly Demon Monarch seemed to appear suddenly, so that Shen Xiang didn't have time to dodge.

"Die!" The Heavenly Demon Monarch laughed fiercely, thinking that his knives were going to pierce Shen Xiang's body, but he saw Shen Xiang's body suddenly gush out of a burst of golden-red light, only to see that Shen Xiang's body was suddenly covered by golden-red scale armor, and the arm holding the Blue Dragon Demon Slayer Knife also turned into a dragon claw!

Shen Xiang looked like a god of war wearing dragon armor now, and the golden-red scale armor fire and thunder on his body were beating, revealing a strong fire and thunder aura, permeating the surroundings.

"The guys who practice Tai Chi Dragon Descending Gong are really like this, this is his martial soul, it seems that he has been forced into a desperate situation!" the demon queen said in a deep voice, as if she was thinking about something in her beautiful eyes.

Shen Xiang released the martial soul and integrated it into his body, making himself clothed in dragon armor, which produced a very strong defensive power, and at the same time, one arm also turned into a dragon hand, allowing him to even more induce the power in the Blue Dragon Demon Slayer Knife.

"Fire and thunder attributes, how come the martial soul of the little uncle is not the Five Elements Dragon Soul like the ancestor?" Gu Dongchen said.

"This little devil is really powerful, if any of us go up, I'm afraid it would have been devoured by the Heavenly Demon Monarch long ago, Shen Xiang has the strength to restrain this kind of demon, and the evil power of the Heavenly Demon Monarch can't pose a threat to him, otherwise, with the gap between them, Shen Xiang can't hold ten moves at all!" Although the demon queen didn't plan to do anything to Shen Xiang, Shen Xiang did make her feel terrified, if she grew up in the future, Shen Xiang killed the demons indiscriminately, they would be difficult to deal with.

What the powerhouses didn't know was that under Shen Xiang's dragon armor, there was also a hidden Xuanwu Vajra armor, and it was strange that the Demon King pierced through that day!

"You ......" The Heavenly Demon Monarch seemed to have discovered something, and he could feel that there was something terrifying hidden in Shen Xiang's body.

Shen Xiang's body trembled, and the demon-suppressing holy power surged, spurting out from his body, turning into nine golden dragons, opening their teeth and dancing claws, roaring again and again, and the nine dragons became one, turning into a huge dragon head, burning with the fire of Qiankun, and slamming into the chest of the Heavenly Demon King!

Boom Boom Boom ......

A wave of golden-red light vibrated out, and at the same time, a ball of golden-red flames burst out, drowning Shen Xiang and the Heavenly Demon Monarch in it.

In the midst of the flames, bursts of thunderbolts exploded, and golden-red thunder rained down like a shower, sending out a shocking thunderbolt, and each thunderbolt contained the power of the ninth layer of demonic power!

Shen Xiang has used these martial arts flexibly, and they can be fused together and appear in many forms!

"The ninth layer of demon suppression, the holy power of demon suppression, and ...... If I'm not mistaken, his flame should be the legendary Qiankun Fire!" "The Demon Queen is worthy of being a powerhouse from the Heavenly Realm, and she has seen more things than others.

When the powerhouses heard the words of the demon queen, they immediately let out a low sigh, Shen Xiang's flame turned out to be Qiankun fire, this is the supreme in the alchemy flame.

"No wonder his alchemy is so powerful, I see!" Mu Jialan muttered in a low voice, she had seen Shen Xiang alchemy, but at that time, Shen Xiang appeared as Li Renshan.

The sea of fire and thunder, the demon suppression holy power is overwhelming, so that many demons feel very more than that, when the demon monarch was struck by the thunder, he let out bursts of roars, and it can be seen that Shen Xiang's attack is not so effective, this is also very normal, Shen Xiang's cultivation is too much different from the heavenly demon monarch, and it is only by relying on his own strength to restrain demons that he can come to this point.

Shen Xiang leaped out of the sea of fire, only to see his expression condensed, the demon-suppressing holy power on his body disappeared, and the aura of his whole person suddenly converged, just when the strong people were puzzled, a murderous aura surged!

The powerhouses quickly thought that Shen Xiang might be going to use the Heaven and Earth Killing Technique!

Legend has it that cultivating the Heaven and Earth Killing Technique requires a very terrifying murderous aura to do it, and now the murderous aura released by Shen Xiang makes people tremble, it is hard to imagine that Shen Xiang's small body actually contains such a terrifying killing aura, how did this happen?

Legend has it that many people went mad and became a demon killer because they practiced the Heaven and Earth Killing Technique and accumulated a large amount of killing qi, but the young Shen Xiang was very good at controlling this vast killing qi like a sea, which was incomprehensible.

"What are you going to do?" Feeling this murderous aura, the Heavenly Demon Monarch suddenly recalled the crazy slaughtering appearance of the Ten Heavenly Emperors back then, when their powerful Purgatory Heavenly Demons were hacked to death by the Ten Heavenly Emperors with the Green Dragon Demon Slayer Knife like grass.
