Xu Zifan thought of using the forbidden level spell of Heaven and Earth Returning to Blood Spell to fight poison with poison and resolve the problem of mismatch between his soul age and physical age.

This method, Xu Zifan has speculated based on the characteristics of the Heaven and Earth Returning Blood Mantra, and theoretically speaking, it is completely effective.

However, to deal with the Mongolian steppe Howling Moon Wolf God, it is not enough to use this kind of taboo-level spell, and the problem that his soul age and physical age do not match, at this time, his realm is still low, and it has not had any major impact on him, so based on the principle that good steel is used on the blade, he will use the Heaven and Earth Blood Curse in some bad situations.

The third direction of Xu Zifan's cultivation is martial arts, and this direction is also Xu Zifan's longest cultivation time, and he has studied in this direction most of the time in the Xiaoao Jianghu world.

However, in the direction of martial arts, Xu Zifan lacked the follow-up exercises to improve the realm at this time, but he had the Heavenly Demon Seal Technique.

And the fourth direction of Xu Zifan's cultivation is the cultivation of spiritual power contained in the Taoist Instrument Sutra.

However, in this direction, which is just the opposite of the direction of martial arts, Xu Zifan has spiritual power exercises and alchemy, but he lacks spiritual power martial arts.

So at this moment, Xu Zifan is a little entangled, although he can make progress in every direction, he also has obvious flaws, and he can't be flawless in all directions.

In terms of martial arts, the lack of exercises made his realm improve very slowly, almost stagnant, and at this time, he had not really broken through to the transcendent realm, but he had a god and demon-level martial arts Heavenly Demon Seal.

In terms of spiritual power, there is alchemy, and the potential is endless, and he can continue to improve his spiritual power concentration, but he lacks spiritual power martial arts, and when he encounters a master of strong spiritual power martial arts like the Howling Moon Wolf God, he is a little constrained.

At this time, Xu Zifan was very helpless and entangled, but he could also think about it, the opportunity in his hand was much better than that of other living beings, what was there to be dissatisfied with?

Next, Xu Zifan shook his head, didn't think about it anymore, now it's better to finish the cultivation of the Demon Ancestor Seal in the Heavenly Demon Seal Recipe first.

This is not to say that he has no confidence in killing the Howling Moon Wolf God at this time, the fact is that because the Demon Ancestor Seal has almost been cultivated, and it will not be delayed for long, so Xu Zifan wants to completely learn this powerful seal trick, and then go north to kill the enemy, the stronger his ability, there is no harm in all, and the safer it will be to go out and walk the world.

At this moment, in the sea of Xu Zifan's purple mansion, there is a mysterious small blue tower rising and falling, and in the small blue tower, there is a figure sitting on each floor, which looks extremely mysterious against the background of the misty blue fog.

Especially the four floors below the small tower, the humanoid figure sitting in it is even more bizarre and extraordinary.

Inside the first layer, there was a blood-colored figure, with a strange and ominous aura, it was Xu Zifan who was using the blue tower-shaped alien fruit to practice the Heaven and Earth Blood Mantra.

And inside the second layer, there is a silver figure, the aura is extremely majestic, shocking, like a real dragon entrenched here, it is Xu Zifan who is using the blue tower-shaped alien fruit to comprehend the heavenly body alchemy.

Inside the third layer, there is a black figure with horns on its head, demonic aura, terrifying aura, terrifying, terrifying, this is Xu Zifan using the blue fruit to practice the Heavenly Demon Seal.

And within the fourth layer, a figure, surrounded by clear light, surrounded by ancient and mysterious symbols, is Xu Zifan in the Taoist Sutra.

This is Xu Zifan's Four Great Dao Fruits, and it is also the practice he majored in.

At this moment, Xu Zifan was sitting cross-legged on the ground, the clear light at the center of his eyebrows was surging, and the black demon shadow within the third layer of the blue tower-shaped alien fruit waved his arm, and he was quickly sealing, and suddenly the terrifying aura was permeated, and the black mist was surging.

At the same time, Xu Zifan himself was like the black shadow, his arm waved rapidly, drawing an inexplicable trajectory in the void in front of him.

Demon Ancestor Seal!

Xu Zifan drank softly in his mouth, his hands were sealed, and suddenly a black mist surged out from around his body, and a terrifying aura descended, shocking people's hearts.

Inside the blue tower-shaped strange fruit, next to the black shadow, the black mist gradually condensed, and finally converged into a black shadow, with two horns on its head and blood-red eyes, which was extremely terrifying.

And beside Xu Zifan,

At this time, it was the same, a black demon shadow with two horns on its head was condensed, surrounded by a ribbon of black mist, and its true face could not be seen clearly, but its blood-red eyes flashed in the black fog with a cruel bloodthirsty, domineering light.

And at the moment when the black demon shadow was condensed, the entire Feilai Peak actually dimmed, and at the same moment, a mighty terrifying intent spread, and this terrifying intent was truly terrifying to all souls, earth-shattering, and terrifying to all living beings.

At this moment, it seemed that there was really a real Heavenly Demon Ancestor descending into the world, and the extreme horror made Xu Zifan a little surprised.

Outside Xu Zifan's door, Xiao Shuang, who was practicing his abilities, also felt this extremely terrifying aura at this moment, which made his whole body tense in an instant, and an extreme ferocity permeated out of Zhou's body, full of violence and cruelty, resisting this terrifying aura.

At this moment, although Xu Zifan was sitting cross-legged on the ground, his eyes closed, using the blue tower-shaped alien fruit to cultivate the Demon Ancestor Seal, what was happening next to him, he had already understood it clearly through his divine sense.

Did I summon a true Heavenly Demon? Xu Zifan felt the extreme horror that spread all over the surrounding space at this moment, and his brows furrowed slightly.

Demon Ancestor Seal, condense the shadow of the Heavenly Demon, and kill as you like!

This is the introduction of the Demon Ancestor Seal, which means that this type of seal can condense the shadow of the Heavenly Demon, and the practitioner can rely on it to kill at will.

It is even said in this record that if you practice to the highest depths, you are likely to summon a real heavenly demon and do something to kill.

With Xu Zifan's realm at this time, there is still a long way to go from the highest depth, but Xu Zifan still feels that the demon shadow beside him at this time seems to be like a living thing.

Is this a summoning spell or an out-of-body incarnation? Xu Zifan was extremely puzzled in his heart, he himself felt a little throbbing in his heart for the magic shadow summoned by this seal, this was very incredible, how could there be his own seal method, the condensed things, made him feel a little uncomfortable.

At this time, Xu Zifan thought carefully in his heart, and felt more and more that something was wrong, but he couldn't see what was wrong.

Kill!

Xu Zifan's mind moved, the seal in his hand changed, and he was trying to drive this demon shadow.

And as the seal in Xu Zifan's hand changed, he saw that the black demon shadow wrapped in black fog beside him instantly turned into a wisp of black smoke, which was extremely fast, and appeared on the ground in front of him in the blink of an eye.

Then the black shadow stretched out a claw arm wrapped in black mist, and swung out a palm, slamming into the ground.

Rumble!

The earth trembled and exploded, and a deep pit appeared directly above the ground.

At this moment, the seal in Xu Zifan's hand changed again, and the black demon shadow suddenly disappeared in place, turning into a wisp of black smoke, and appeared in another place in the blink of an eye.

This time, the black shadow demon's mouth opened wide, and a black column of air erupted, once again blasting the ground into a deep pit.

Next, as Xu Zifan's technique changed, the black demon shadow floated around, the speed was extremely fast, moving according to his heart, and the power of the battle was also terrifying.

In the end, the seal in Xu Zifan's hand dispersed, and the black demon shadow also turned into black mist and dissipated between heaven and earth.

And in this process, the blue tower-shaped alien fruit, the black demon shadow within the third layer, the black mist around its body rolled out, gushing out of the small tower, and merged into Xu Zifan's Purple Mansion Zhihai.

At this moment, Xu Zifan's eyes slowly opened, and a blood-colored light flashed away.

Today, the Demon Ancestor Seal has finally come to fruition!

Under the blue tower-shaped alien fruit to assist in enlightenment, the Demon Ancestor Seal has finally been practiced, and in the future, with the addition of Xu Zifan's skill realm, the power of this seal will also be greatly improved, until finally, according to the records, the real Heavenly Demon may be condensed.

This style of sealing, like a summoning technique, is also like an incarnation outside the body, and it is also like a puppet driving technique, which makes Xu Zifan feel extremely surprised.

The black demon shadow that condensed out, Xu Zifan felt it to himself, and he could feel that if all his strength was exerted, it would definitely be no less than the Great Evil King he had killed at the beginning, or even stronger, and this meant that this style seal could be summoned

Produce a transcendental-level powerhouse to fight for himself.

This is a bit terrifying, in the future, Xu Zifan will fight the enemy, which is equivalent to two to one, and the increase in his own strength is not as simple as one plus one equals two, but one plus one is greater than two.

However, although this Demon Ancestor Seal Technique was extremely powerful, Xu Zifan felt a little strange in his heart, and there was a trace of solemnity, because he didn't know what he had condensed, and the aura on his body even felt a little throbbing in his heart.

And the most important thing is that the black demon shadow that he condensed, he actually felt like a living creature from his body, an independent individual, which was also the most puzzling thing for Xu Zifan, it stands to reason that this situation could not happen at all.

This situation made Xu Zifan feel that something was wrong, but he couldn't say what was wrong.

Isn't there a problem with this exercise? Xu Zifan frowned, he was thinking.

Could it be that this Heavenly Demon Seal Technique is really just a great technique of attacking and killing? Are there any other secrets within?

He didn't know this aspect, and he couldn't see it with his current knowledge, but from today on, Xu Zifan paid attention to this set of Heavenly Demon Seal Tricks in his heart.

At this moment, the Demon Ancestor Seal has been practiced, it is time for Xu Zifan to go north to kill the wolf god, in today's battle, the Xiaoyue wolf god has lost a spiritual power, and it will definitely be gained, take advantage of its illness, let it be sick, this is the best time to kill it.

Xu Zifan stood up from the ground, stepped out, and had reached the door, Xiaoshuang's body was fierce and violent at this time, like a big demon, and the momentum was amazing.

At this moment, Xu Zifan is even more optimistic about Xiaoshuang's potential, ordinary creatures should tremble with fear under that terrifying demonic aura, even the great sage centipede of the king-level realm once fled in front of the terrifying demonic qi released when he used the Great Heavenly Demon Hand, and Xiaoshuang did not hesitate at all in front of the terrifying demonic qi that suddenly came, but competed against each other, releasing fierce power, and wanted to meet with the terrifying demonic qi according to this.

At this time, Xu Zifan knew that Xiao Shuang was motivated by the terrifying demonic qi when he cultivated the Demon Ancestor Seal by himself.

Xiaoshuang, calm down!

Xu Zifan whispered, and a wisp of purple clear qi shot out, covering his whole body, helping him suppress the ferocity in his instinct.

With Xu Zifan's help, the blood in Xiaoshuang's eyes faded and gradually regained his calm.

You're such a militant! Xu Zifan opened his mouth and said with a smile.

When Xiaoshuang heard this, he said: Well, big brother, I can't help it, is that brother, are you practicing? The voice of the young girl came very clearly, and there was a strong sense of worry in her words.

Yes, that's my brother practicing, and when you're with my brother in the future, you can relax and don't have to worry about your brother, you know? Little Shuang! Xu Zifan opened his mouth to respond, and earnestly advised.

Got it, brother!

Xiaoshuang was also simply and directly agreed to Xu Zifan.

Didn't have a seizure today, right? Xu Zifan opened his mouth again and asked, it was about Xiaoshuang's Dao injury, although he drank a lot of strange water, but the hidden danger in his body was only suppressed, and it continued to exist.

Big brother, don't worry, I feel that I am no different from normal beings at the moment. Xiaoshuang said happily, wagging two frightening tails, swinging around, terrifying...

If something happens in the future, let me know in time! Xu Zifan said worriedly.

Okay, big brother, I listen to you! Xiaoshuang spoke, and his voice was very immature and very cute.

Next, Xu Zifan put Xiaoshuang on his shoulder, and then went out of Feilai Peak, said goodbye to his parents, and informed the group of demon kings of the news of his departure, and instructed many demon kings to be more careful and protect Qinling.

Knowing that Xu Zifan was going north to the grassland to kill the Howling Moon Wolf God, many demon kings recommended themselves and wanted to follow, but in the end Xu Zifan refused all, Qinling is the foundation, and now at this stage, it is better for the demons of Qinling to improve their strength in Qinling, and it is not beneficial to go out to fight for dominance in the world.

Subsequently, Xu Zifan only left with Xiaoshuang.

This goes to the grassland, there are thousands of miles away, Xu Zifan is all the way

, , did not rush to the road, but while walking, while collecting medicinal materials that can increase the power of qi and blood, at the same time, he was also killing some demons and monsters who attacked him, one to collect flesh and blood essence, and the other to prepare food for Xiaoshuang.

The weather at this time is a little cold, especially at night, and the temperature sometimes drops below freezing.

This is the belated late late autumn, in the past this time in the north of China was already considered the deep winter wax moon, but after the change of heaven and earth, everything has changed.

The weather has changed a lot from what it used to be, and even more so with the landscape, after a series of major earthquakes, much of the terrain has changed completely and is unrecognizable to locals.

After a long night of trekking, early the next morning, Xu Zifan came to a human settlement called Changle Town, and after this town, two hundred miles further on, is the Mongolian steppe.
