The magic knife technique of the Demon Knife Gate can be turned into sword qi to refine the demon baby with the evil spirit qi, and the demon baby refined is infinitely powerful and has great attack power.

And the Demon Sword Sect's Demon Sword Skill can also be turned into sword qi to refine the Demon Infant with the Demon Spirit, and the Demon Infant that is tempered is weird and changeable, and it is pervasive.

The exercises of the Great Holy Gate are to temper the demon body and the demon baby at the same time with the earthly evil aura, the demon baby is constantly strong, but the physical body is infinitely powerful, flexible and agile, and the speed is amazing.

The exercises of the Demon Fox Hill can use the fire-based earth evil aura to refine the body and the demon baby, and turn the flame into a flame tail, which is similar to the telekinetic energy elemental skill, but these flame tails are rooted in their own body, as if extending out of the limbs, they are more controllable, but after they are broken, they will also be painfully injured.

After a whole day of deduction, Yang Xiaole finally integrated the exercises of these sects, as well as the exercises such as the Demon Slaying Divine Technique and the Mental Power Yuan Gong into the Blood Demon Killing Divine Skill that he majored in, and created a Demon God Technique that was more suitable for him.

This Demon God Technique can absorb all kinds of Earth Evil Aura, condense the world-destroying Demon Flame Sword Qi with the ten directions that destroy everything, and then use the World-Destroying Demon Flame Sword Qi to refine the Yuan Infant and the flesh body, which can temper the Yuan Infant and the physical body with infinite power and agility, and can also transform the World-Destroying Demon Flame Sword Qi into various weapons and equipment such as the World-Destroying Demon Sword, the World-Destroying Demon Shield, the World-Destroying Demon Whip, and the World-Destroying Demon Armor for combat.

Yang Xiaole also came up with a way to link these embodied weapons and equipment with the Heaven-Defying Demon Armor, so that these embodied weapons and equipment would be able to obtain the energy bonus of the Heaven-Defying Demon Armor, and once destroyed, he himself would not be attacked and affected the battle.

With this Demon God Technique, Yang Xiaole could begin to absorb the Earth Demon Aura and quickly improve his strength.

It just so happened that the mountain gate of the Blood Demon Sect and the Immortal Sword Gate was hidden in his personal space.

When he transferred the mountain gates of the two sects into his personal space, he also transferred their earth-shattering spirit veins into the space.

The Earth Evil Spirit Vein is actually a kind of spiritual jade mine, which can automatically absorb the Heaven and Earth Yuan Qi and condense it into the Earth Evil Spiritual Qi.

After the two mountain gates' Earth Evil Spiritual Veins were transplanted, the Earth Evil Spiritual Qi once leaked and dissipated a lot, but after absorbing the Heaven and Earth Yuan Qi for so long, some Earth Demon Spiritual Qi had been recondensed.

So, Yang Xiaole came to the mountain gate of the Blood Demon Sect, entered the Blood Demon Sect's Blood Demon Spiritual Vein, and began to absorb the Blood Demon Spiritual Qi of this Earth Demon Spirit Vein, and cultivated the Demon God Recipe that had just been created.

I saw Yang Xiaole take a deep breath, and the blood evil aura in the blood evil spirit vein suddenly surged from all directions, frantically injected into his body from the acupuncture points of his body, and then gushed out from the pores of his whole body, bringing out a large amount of impurities, making his whole person turn into a blood-red true qi cocoon.

This blood-red True Qi cocoon continued to expand and contract, as if a huge heart was constantly fluctuating.

Gradually, the blood aura of the entire Blood Demon Spirit Vein was absorbed by Yang Xiaole.

Then, Yang Xiaole began to urge the Ten Directions to Annihilate Sword Intent and Blood Flame Ability, transforming these bloody auras into World-Destroying Demon Flame Sword Qi.

Soon, the blood-colored True Qi cocoon no longer expanded and contracted, but ignited a raging blood flame, turning into a huge blood-colored fireball.

However, the blood-colored fireball soon continued to shrink, and finally completely converged into Yang Xiaole's body, turning into a more powerful world-destroying demon flame sword qi in Yang Xiaole's meridians, and constantly circulating in his meridians, refining his physical body and Yuan Ying at the same time.

Under the repeated refining of the World Destroying Demon Flame Sword Qi, Yang Xiaole's physical body began to collapse continuously, and it continued to regenerate under the effect of his powerful bloodline.

And his Demon God Yuan Infant also kept collapsing, and then under the effect of special exercises, he continued to heal.

Collapsing and regenerating like this, his physical body and primordial infant became stronger and stronger.

Finally, after three days and three nights of cultivation, Yang Xiaole initially practiced the Demon God Technique, and a terrifying world-destroying demon flame sword qi was condensed in his body.

In addition, his comprehensive combat effectiveness has also increased to more than 2,100 points.

Then, Yang Xiaole did the same and absorbed the aura in the Immortal Sword Gate's Earth Demon Spirit Vein.

After initially practicing the Demon God Technique, Yang Xiaole absorbed the Earth Demon Spiritual Qi even faster.

As a result, the World-Destroying Demon Flame Sword Qi in his body doubled again, and his comprehensive combat power also broke through to more than two thousand four hundred points in one fell swoop, just reaching the same level as a powerhouse in the late stage of the Void Restoration who had survived a Heavenly Tribulation.

But at this time, it is not so easy for Yang Xiaole to continue to improve his strength, with his talent, in fact, he can continue to absorb the earth's evil aura, and the maximum should be able to increase his comprehensive combat strength to more than three thousand points, before reaching the limit of the early stage of returning to the void.

However, the Earth Demon Spirit Vein is not a big road commodity, but a resource that everyone covets, and most of them are occupied by the Great Gate Sect.

Unless Yang Xiaole can destroy a few more sects, occupy their Earth Evil Spirit Vein, or find the Earth Demon Spirit Vein that has not yet been discovered, it will probably be difficult for Yang Xiaole to improve his strength in a short period of time.

So, Yang Xiaole ended his cultivation and continued to fly towards the headquarters of the Demon Axis.

This time, the aura released by Yang Xiaole has become even more terrifying, those young demon cultivators and young demon cultivators are all taken by his breath, and they don't dare to come to challenge it easily.

Finally, Yang Xiaole came to the headquarters of the Demon Axis unimpeded.

In the distance, a black city standing between the mountains and mountains appeared in front of Yang Xiaole.

The walls of this city are made of black rocks, and outside the walls, there is also a layer of black energy light, and in addition, there is a layer of black oppressive clouds suspended in the sky above the city.

The clouds continued to rotate, forming a huge whirlpool, the center of the whirlpool was pitch black, and from time to time black lightning flashed, like a passage to the demon world.

When Yang Xiaole saw this scene, he couldn't help muttering: "It is worthy of the Demon Domain City, the headquarters of the Demon Axis, and the scene of this city is really similar to the legendary Demon Domain!" ”

After watching for a while, Yang Xiaole continued to urge the Blood Shadow to escape and flew towards Demon Domain City.

After a while, Yang Xiaole finally flew in front of Demon City and landed at the gate of Demon City.

At the gate of Demon Domain City, there is a group of soldiers in black armor collecting the entrance fee to the city, and one person actually asks for a low-grade spirit stone, so most of the people who come and go are demon cultivators.

Yang Xiaole also saw some ordinary humans, but most of them were ragged, handcuffed and shackled, and were whipped from time to time, and they seemed to be slaves and furnaces captured by demon cultivators and demon cultivators.

Seeing this, Yang Xiaole couldn't help but narrow his eyes, and from the bottom of his heart, he felt a wave of anger towards this demon axis that wantonly bullied ordinary people, because he had been an ordinary person before, and he felt the same way when he saw ordinary people being bullied by demon cultivators and demon cultivators.

Yang Xiaole's Tao is to use anger as power, demon flame as the blade, and sweep away the evil in the world, what this demon axis has done has violated Yang Xiaole's way and touched his scales.

If Yang Xiaole didn't deal with this demon axis, it would go against his own way, causing his thoughts to be inaccessible and his skills difficult to improve.

"Hmph, it looks like I'm going to have to make a good mess here!" Yang Xiaole smiled coldly, handed over a spirit stone, and walked into Demon Domain City.
