Sitting there cross-legged, Zhou Yun entered the boundary crystal space with a trace of thought, and suddenly, Zhou Yun's condensation in the boundary crystal space stood up from the inky world.

Looking up, the giant tree was still there, and in a few days, the giant tree seemed to have grown a little more than before, and became more leafy.

Moving his body slightly, Zhou Yun slowly walked in front of the giant tree and said loudly, "Senior, junior Zhou Yun has something important to ask, please show up." ”

Zhou Yun's words fell for a long time, and the inky earth finally let out a slight tremor, but this time, the true body of the Hydra Demon did not appear, but a voice came from the giant tree.

"What's the matter?" the voice from the giant tree was old and far away, and there was a bit of evil and dark aura, it was the voice of the hydra demon.

"Senior, I have fused a Black Flame Crystal according to your instructions, and my cultivation has successfully broken through to the Martial Saint Realm, thank you for your advice. Clenching his fist slightly at the giant tree, Zhou Yun thanked him.

In this matter, Zhou Yun still has to thank the Hydra Demon, his guidance has indeed made Zhou Yun get a lot of benefits.

"Well, you have this Chaos Crystal, you fuse and cultivate every day, your physique is constantly changing, and your talent is getting stronger and stronger. I have also felt your power, the effect you achieved by using the Black Flame Crystal at this moment is better than I expected, and when you stabilize in the Martial Saint Realm, and the strength of your true power is increasing for a while, I will continue to guide you in the next step of cultivation. After listening to Zhou Yun's thanks, the voice of the Hydra Demon came out again.

"Thank you, senior. Respectfully bowed to the giant tree, and Zhou Yun spoke sincerely.

For this Hydra Demon, Zhou Yun has a lot of respect in his heart, but this respect does not mean that Zhou Yun is stupid, before he is sure that letting go of the Hydra Demon will not threaten his own safety, Zhou Yun will not let him go no matter what.

But Zhou Yun will also continue to work hard to improve his cultivation as soon as possible, so that maybe the time for the Hydra Demon to break away from him will be earlier.

The Hydra Demon is an ancient beast, extremely powerful, existing for hundreds of thousands of years, whether it is cultivation, status, or even heart, it is unparalleled. Zhou Yun didn't expect to be able to take such a strange beast under his command, but with the guidance of the Hydra Demon, it was still necessary to grow as fast as possible.

"Senior, I have one thing I want to ask my senior to help with. After thanking him, Zhou Yun once again spoke out respectfully.

"Well, you name it. There was a moment of silence, and the voice of the Hydra Demon came out again. In this conversation, every time Zhou Yun asked, the Hydra Demon had to wait a long time before responding.

Guessing that the Hydra Demon was probably cultivating, Zhou Yun didn't waste time, and spoke directly, "Senior, I want to control some martial artists so that they don't rebel, I wonder if the predecessor has any way?"

"Hmph, there is so much spiritual poison in this Chaos Crystal, you want to ask me about such a thing?" After a moment, the words of the Hydra Demon came out again with a slight sneer.

Poison?

There was a blank expression on his face, and Zhou Yun was a little confused, "Please also ask the seniors to make it clear." ”

"You go around the tree and go straight forward fifty miles, and you will find it. After finding those spirit poisons, you only need to hit the Chong Ling Acupoint on the top of the right index finger of the Heavenly Spirit Vein in your body with all your strength to achieve the effect of linking the Chong Ling Acupoint with the Chaos Crystal, and then you can use those poisons to control the people you want to control. The person who is controlled will not have a seizure within three years, and his cultivation will not be able to improve, and after three years, if he cannot detoxify, he will die violently. This time, Zhou Yun waited longer, and after about a minute, the voice of the Hydra Demon came out.

After saying this, the ground under Zhou Yun's feet trembled again, and after a while, the earth returned to calm, and Zhou Yun could no longer feel the existence of the Hydra Demon.

It seems that the Hydra Devil's Cube is indeed cultivating, and after giving Zhou Yun proper guidance, the Hydra Devil has once again fallen into cultivation.

"Heavenly Spirit Vein?Chong Ling Acupoint?Could it be that this Heavenly Spirit Vein is the name of the mysterious vein in my body? If this is the case, there is indeed an acupuncture point on the tip of the index finger of my right hand above this mysterious vein, and it should be the Heavenly Spirit Acupoint. Feeling the mysterious vein in his body, Zhou Yun thought silently in his heart.

Thinking back to the first time he met the Hydra Demon in the pit of the Mirror Lake Secret Realm, the Hydra Demon also mentioned the matter of the Heavenly Spirit Vein, and now it seems that this vein on his body is indeed called the Heavenly Spirit Vein.

Now, there is already a lot of power in the Heavenly Spirit Vein in Zhou Yun's body, and these powers are not true powers, but a kind of mysterious and mysterious power, which is very mysterious. Although I don't know how to cultivate and improve this power, and I don't know how to use this power, if I just mobilize this power in my body to impact a certain acupuncture point, there should be no problem.

When a martial artist cultivates, if each acupuncture point of the eight veins of the Qi Jing in the body wants to run smoothly, and at the same time achieve the effect of storing part of the true power, it is also necessary to mobilize the impact of real power to open this acupuncture point. Impacting acupuncture points and opening acupuncture points is so difficult that Zhou Yun can't be overwhelmed.

"I just don't know what's fifty miles ahead of this inky world. With a hint of doubt, Zhou Yun bypassed the giant tree and walked in the direction guided by the Hydra Demon.

Zhou Yun's condensation is now very strong, and the journey of fifty miles is not a problem at all.

Advancing rapidly, after the time of a stick of incense, Zhou Yun had already walked a distance of fifty miles.

"Here, it seems that there is nothing, is it in the wrong place?" On the way forward, Zhou Yun has been carefully observing around, he has never found anything else in this inky world before, but listening to the hydra demon, there are actually some things in this inky world.

"Hmm, what is that?" Suddenly, a faint touch of green appeared in front of him, and seeing that touch of green, Zhou Yun's brows immediately frowned slightly.

The green glow seemed to be coming from underground, and when you looked along the horizon, you couldn't see anything at all, and you could only see it clearly when you looked down closely.

Walking over quickly, Zhou Yun was immediately stunned by the scene in front of him, "This ...... , is this soul locking incense?"

In front of Zhou Yun's eyes, a large pit with a radius of about five meters was quietly existing under the ground of the inky world, and in that big pit, streams of rich green poisonous gas were constantly shining, and when he saw this green poisonous gas, Zhou Yun immediately judged that this was the kind of soul-locking incense in his sister Zhou Xue's body at that time!

He had cultivated with this soul lock incense poison before, and Zhou Yun was very familiar with such a toxin.

"Could it be that the Hydra Demon asked me to attack the Chong Spirit Acupoint, just to let me open up the connection between my body and this realm crystal, and then use this soul lock incense to poison those martial artists, and then control them for three years? But if we can't come back within three years, then these martial artists will all die?" Looking at the rich green poisonous gas in the big pit, Zhou Yun's brows furrowed tightly.

Before, those warriors of the Luo family were all doing things for Luo Tian, so they were innocent, but now, these warriors have all taken refuge under his command and are willing to serve the Liu family. It was necessary to find a way to control them so that they could obey Liu Xiaohan and Liu Xiaofeng.

But if it is a thing like soul locking incense, it is likely to directly kill these warriors. Zhou Yun couldn't do such a thing.

"After all, this is not the Tianyuan Continent, but another continent, I don't know if I can come back to this place, if I really want to do this, in case I can't come back, it will really be a sin." In this matter, it is better to ask the third princess first. Standing there, Zhou Yun thought silently for a moment, and finally made a decision.

The condensation stagnated there, and in the carriage, Zhou Yun's body also opened its eyes.

"Third princess, I have a question. Looking at Li Wanqiu, who was still cultivating with his eyes closed, Zhou Yun asked loudly.

After listening to Zhou Yun's words, Li Wanqiu's eyes slowly opened, "Well, you ask." ”

"Third princess, is it convenient for me to come here in the future?" The tone was calm, and Zhou Yun asked out loud. This is what Zhou Yun is most concerned about now, being able to use soul locking incense is of course the best result, first of all, this toxin will not damage the body, but it will inhibit the improvement of cultivation, once the toxin is removed, it still has no effect.

Second, this kind of control method is more familiar to Zhou Yun, if Zhou Yun can still come here in the next three years, then there is no problem in using soul locking incense.

Liu Xiaofeng, Zhou Yun is very optimistic in his heart, this kid is only thirteen years old now, if he grows up well, after three years, he should also be able to protect himself and Liu Xiaohan.

Moreover, Liu Xiaohan's cultivation has been steadily improving recently, and after getting Zhou Yun's guidance, I believe she will also improve quickly. Moreover, when he goes back this time, Zhou Yun will also give them a big gift to their sister and brother.

After listening to Zhou Yun's words, a trace of surprise flashed in Li Wanqiu's eyes. At first, Li Wanqiu thought that Zhou Yun couldn't let go of Liu Xiaohan and wanted to come back again. But looking at Zhou Yun's clear eyes, Li Wanqiu judged that what Zhou Yun had in his heart was not greedy for beauty at all.

Thinking that he would care about this, Li Wanqiu's face also showed a hint of self-deprecation, and he shook his head, Li Wanqiu immediately spoke, "If you want to come back here to have a look, it shouldn't be a problem, this time it is the first place in the Shenwei training camp, and you will also have this right in the future." ”

After listening to Li Wanqiu's words, the worries in Zhou Yun's heart finally let go, if this is the case, then there is no problem with using soul locking incense.

"Thank you, Third Princess. After thanking Li Wanqiu, Zhou Yun's mind once again entered the boundary crystal space.

Seeing Zhou Yun close his breath, Li Wanqiu once again devoted himself to his cultivation.

In the boundary crystal space, on the vast inky earth, Zhou Yun began to follow the instructions of the Hydra Demon to impact the Chong Ling Acupoint at the top of the right index finger of the Heavenly Spirit Vein in his body, and the power in the Heavenly Spirit Vein was mobilized by Zhou Yun and began to run rapidly.

At this time, Zhou Yun's body, sitting in the carriage, also began to adjust the power in the inner heavenly spirit vein at the same time.

At this moment, the movements of Zhou Yun's body and condensation body were almost identical, and there was no trace of difference.

After running the power in the spiritual veins of that day for a few turns, he felt that the time had come, and Zhou Yun immediately concentrated his strength and rushed out towards the Chong Ling Acupoint at the tip of his index finger.

Rumble!!

That mysterious power jumped up and slammed into the Chong Ling Cave in the Heavenly Spirit Vein, and suddenly, Zhou Yun felt that the connection between himself and the Boundary Crystal had been opened up all of a sudden!
