Sun Fei couldn't cling to words to describe his surprise at the moment, if it weren't for the fact that he had the memory in the Immortal Medicine True Scripture, I'm afraid he wouldn't even know what this thing was.

The meridian lines in the human body should have been determined a long time ago, but throughout the ages, no matter what kind of exercises a cultivator cultivates or what qi he refines, he can only absorb spiritual energy and run in fixed meridians, and this has never changed.

However, for cultivators who ascend to heaven, whether they are immortals, Buddhas, or demons, they all possess the ability to transform their bodies almost unlimitedly.

Therefore, in order to pursue greater strength, many immortals forcibly establish connections between certain acupuncture points in their bodies, and the unnatural meridians formed by this are called virtual meridians.

There are many ways to use the void veins, and no matter how many combinations of acupuncture points and types are opened, even the same acupuncture points have different effects due to the different routes of the meridians.

And the void vein in the body of the person in front of him is a special slave seal that the Heavenly Demon likes to use on his followers or concubines who cultivate the Demon Dao, called the Heavenly Demon Slave Seal. His own Immortal Demon Slave Seal slightly borrowed from this Heavenly Demon Slave Seal, but the difference is that his Immortal Demon Slave Seal can be used as long as he is a cultivator, and he does not need to forcibly open the acupuncture points to create void veins.

And the Heavenly Demon Slave Seal is a rather stubborn slave seal, and the Void Pulse is equivalent to a remote control, and its owner can control the amount of Qi that this slave under his command can use, and even destroy the Void Pulse and completely abolish the cultivation of this slave.

Although it requires immortal-level cultivation, the Heavenly Demon Slave Seal is an initial finished product from a long, long time ago, not even a semi-finished product, after all, it can only abolish the cultivation of this slave at most, but it cannot control the life and death of this slave.

And his own Immortal Demon Slave Seal is an obvious improved version, and it has the advantage of not being able to count it even with a finger compared to the Heavenly Demon Slave Seal.

However, even if you think about it with your toes, you know that there are a lot of people in the Demon Dao who cultivate the Demon Dao, and thousands of years have passed, if there is a demon who is interested in the Heavenly Demon Slave Seal, he will definitely explore a more practical way to make it more practical, and will not take this most primitive way.

The existence of the Immortal Demon Slave Seal made Sun Fei firm in his idea, and it was obvious that before the Immortal Demon Slave Seal appeared, an improved version of the Heavenly Demon Slave Seal had already appeared.

The appearance of this primitive Heavenly Demon Slave Seal on this person's body is a big problem in itself, this kind of thing should not exist a long time ago!

If you want to explain the origin of this Heavenly Demon Slave Seal, then there is only one possibility.

This person had originally ascended to heaven and became a demon, but he was sealed by a certain demon who cultivated to a higher level of demonic seed, and after a period of time, he came to the earth, and then lived until now, but how long he stayed in the sky and how long he stayed on the earth, Sun Fei still couldn't see it.

But there is only one point, Sun Fei is extremely sure.

The person in front of him is not an ordinary person at all, he is a demon who has ascended to heaven!

Since he has ascended to heaven, his cultivation is naturally countless times stronger than himself!

After hearing Sun Fei's words, the young man grinned and said, "Sure enough, the divine doctor is the divine doctor, and it really deserves its name." I was only thinking of trying my luck, but I didn't expect to really turn around and meet a god who has the ability to unlock my slave seal. ”

Sun Fei couldn't say 10,000 MMPs in his heart at the moment, and scolded secretly in his heart: Damn, this is because he met himself, no matter how awesome the magic doctor in this world, he can't give you the slave seal planted by the Heavenly Demon!

Sun Fei sighed and said, "Alas...... If you want to unravel, it's not that you can't unravel, after all, this is shoddy...... There are too many immature places in the primordial Heavenly Demon Slave Seal, even if it is not enough to cultivate the immortal demon, there is still a chance to unlock it, but it is just ......"

"You want to say, you don't have that ability yet?" The young man asked with a wry smile with a look of disappointment.

Sun Fei sighed, showed a helpless expression and nodded: "That's right, my level is limited, even if I can see it, I'm afraid I won't be able to help you." ”

Of course, the above words are all lies.

Sun Fei had a helpless expression on his face, but he sneered in his heart. MMP, when I'm missing an eye? If it weren't for the fact that this void vein has restricted your cultivation, and the strength you have taken out now is far less than one percent of your true strength, you would have come to me in such a low voice?

This primitive Heavenly Demon Slave seal has too many flaws, of course I can solve it, but what about after I solve it?

The person in front of him is cultivating the Demon Dao, so he does not have the concept of goodness and virtue of cultivating immortals and cultivating Buddhas all day long. I'm afraid that if he really saves him, the first thing he does is kill himself.

In this world, even if you are strong enough to ascend to heaven and can walk sideways in the world, it is still a troublesome thing to expose the matter of demon cultivation, and exposing the matter of demon cultivation to a stranger who has only one side of the acquaintance, ask who will you kill if you don't kill you?

The young man sighed lightly and said with a forced smile: "That's what a pity. Originally, I thought that if you could really help me remove the Demon Slave Seal, I would give you a fun little thing. Since there is no way to cure it, it is still ......"

"I'm really sorry, I'm limited in my level, so let's try to see if there's any other way." Sun Fei immediately responded.

Damn, what the hell is that "little thing", I care a lot!

Sun Fei secretly slandered himself, although he could hear that he was obviously testing himself, but this "little thing" has different meanings in the mouths of different people. The "little thing" in an ordinary population may really be a worthless little thing such as a pendant. But if it comes out of the mouth of this kind of immortal demon, I'm afraid it will be a superb spiritual weapon!

Seeing Sun Fei's refusal so resolutely, the young man was silent for a moment, shook his head with a chuckle, and said, "Indeed, I can also see that your level is still far behind. ”

"What you said is that the medical road is long, and only by constantly working hard to help more patients can we improve the medical Tao." Sun Fei followed Feng Yingdao, and secretly cursed in his heart that you are not finished, and you will leave quickly if you are fine.

The young man shook his head and said, "No, I'm talking about the level of lying, it's really far from it." ”

"What do you mean by that?" Sun Fei hooked the corner of his mouth and sneered.

Sun Fei immediately became vigilant, it seems that this young man may have used an ability such as galvanizing when he was not paying attention, if she really let her see her thoughts, then she must be ready to dry the frame directly.

The young man smiled indifferently and said, "It's very simple, you inadvertently mentioned this slave seal 'shoddy' before, which shows that you know this slave seal better, and your tone is quite relaxed, which shows that you are very confident." But then you keep saying that you're not good enough, in other words, I can interpret it as, 'You know how to lift, but you don't want to do it.'" I didn't mention any remuneration before that, so you have only one thing to worry about. You're worried right now that once you lift my Heavenly Demon Slave Seal, I'll kill you right away, right? ”

Cut, this bastard's ability to read words and emotions is not small, what a troublesome devil.

The words have come to this point, and Sun Fei didn't intend to cover up uselessly, but sneered and said, "What if I just don't want to save you?" Did you bite me? ”

"Hehe......" The young man suddenly lowered his head and chuckled, then suddenly raised his eyes to look at Sun Fei, and said with a smile, "I really plan to bite you." ”

As soon as the words fell, the young man's figure suddenly appeared in front of Sun Fei!

So fast!

Sun Fei was secretly shocked in his heart, at that moment just now, he didn't see his movements at all, with such a speed, even if he had a witch, he might not be able to keep up!

The current situation did not allow Sun Fei to hesitate any longer, and immediately used the witch kick, planning to escape from here to the door.

Who knows, before Sun Fei could move, his hands were already on his shoulders!

The figure of the young man in front of him immediately disappeared, and when he saw this, Sun Fei reacted, this is the afterimage created by Wu Shan!

"Your response is good, and you're very skilled with the witch's footwork. It's a pity that your qi condensation is too low, and you can't bring out the effect of the witch spirit footwork. The young man said with a smile.

"Why are you ......" Sun Fei gritted his teeth and immediately tried to seal it, but the young man suddenly stretched out his right hand, and a purple rope suddenly appeared out of thin air, tying his hands tightly, making his hands immediately immobile!

Sun Fei looked down, but found that the young man's hand had a black glove embroidered with golden lines at some point, and the arm that stretched out was filled with strong yin qi, which was completely different from what he had just seen, and he was suddenly shocked: "You, what ......the hell are you?"

However, before Sun Fei's words were finished, he suddenly felt a tingling pain in his neck, and the young man behind him actually bit his neck!

Sun Fei immediately felt a purple qi slowly pouring into his body, and even his own Xuan Qi couldn't stop this dark purple qi, allowing it to go straight to his dantian, forcibly occupying nearly half of the position, and dispersing all the extra Xuan Qi to other places in his body.

"This, what is this......" Sun Fei suddenly felt dizzy and muttered weakly.

Sun Fei didn't know if he was hallucinating because of this anger, but he heard a young woman's voice behind him.

"Giggles, here's my little gift to you, I'll be looking for you soon. As long as you unseal the slave seal for me, I promise you that you will be indispensable for your benefits. Other than that...... If I want to force you to untie the slave seal for me, why bother so much, you say? ”

After the voice fell, Sun Fei suddenly felt that there was a sudden loss of support behind him, and immediately took two steps back, leaning against the wall, and still felt that everything was spinning in front of him.

But now, Sun Fei knows something.

That guy's strength is really far beyond his imagination.

Indeed, if he wanted to, even if he was capable now, it would be more than enough to kill himself.

Having said that, that guy's camouflage ability is inevitably too awesome, and even the meridians in his body can be faked, which can almost deceive people in the fairy world.

Sun Fei sighed secretly in his heart, and said in his heart that it was already a great luck to be able to save his life this time, so next time I would give him a free release of the slave seal. As long as he can dismantle the time bomb in his dantian, he will have no more requirements.
