In a cave, the light of the formation flickered, and the faces of the people inside were hideous, and a thick black and red demonic qi flowed above their bodies.

But if you look closely, there is a red gold color on the top, and there is not the slightest demonic qi revealed.

"Bang!"

A piece of inky black magic yuan was petrified into bits and pieces, and sprinkled on the ground.

This is naturally Su Zixuan, he also got a lot of magic yuan stones from Yu Zun, after getting it, he didn't think much about finding a cave very much, and after arranging several layers of formations, he took the magic yuan stone to try.

"Hmm...... It's a lot faster!"

After using a few pieces, Su Zixuan was also a little emotional, and then he didn't say anything and took out a magic yuan stone from the storage bag again.

Su Zixuan held the Demon Yuan Stone in his hand, and the pure Demon Yuan Power impacted Su Zixuan's inner acupoint little by little.

In the human body, there are 12 meridians of the five internal organs and six internal organs, a total of 24 symmetrical left and right, there is a Ren pulse in the center of the front of the body, and there is a Du pulse in the center of the back of the body, and each has a special meridian running through the whole body.

The acupoints of the human body arranged on these fourteen meridians are called positive acupoints.

When he was in the spirit realm, Su Zixuan also cultivated the acupoint seal to one hundred and eighty after advancing to the tribulation period, and he had no way to continue because of the realm.

And now all he has to do is to use these tricks to use the pure magic yuan power in the magic yuan stone to refine and impact one by one.

When he can refine all these one hundred and eighty trick points, it can be regarded as a real advanced True Immortal Realm, and his strength will definitely increase greatly at that time.

In the middle of the formation, Su Zixuan's body was tumbling and boiling like volcanic magma, and slowly the black blood-colored magic yuan power began to pour into his meridian points little by little.

As soon as those demonic powers entered the body, they turned golden, and the golden points of light slowly spread out and flowed into all parts of the body.

A feeling of intense pain ensued.

A burning sensation came from the skin, and the meridians in the body felt as if they were expanding.

At this moment, Su Zixuan's face was pale and permeable, and the pain was abnormal.

"Boy, work hard, this is just a simple conversion of mana and demon power, and it's just a little bit of pain, if you really go to the holy pool of our holy clan, I'm afraid you won't experience the pain, you will have to fall!"

"Yes, I see!"

Su Zixuan was also a little surprised and replied, now that it is so painful, if there is really a chance to enter the holy pool that Yuzun said, then what kind of pain should it be?

"Okay, you cultivate well, I don't think you have to rush to those populated places, it's better to cultivate well, and after the breakthrough, it's not too late to go again!"

Seeing Su Zixuan's expression, Yu Zun also continued.

"Good!"

Then, Su Zixuan endured the terrible pain again and began to cultivate.

He also silently operated the exercises, introducing the thick and pure magic yuan power into the body acupoints.

And just like that, months passed.

"Bang!"

Su Zixuan opened his eyes, and he also felt some mysterious changes in his body.

"Huh...... In this way, it still has some effect!"

After Su Zixuan looked inside, he also laughed at himself, although it was a little painful, but it was still effective, so that he could cultivate with confidence.

Then he took out a Demon Yuan Stone without thinking and continued to cultivate.

He also had to endure the pain in his body and introduce the pure magic yuan power into the skin meridians.

In fact, after such a long time, the pain is not as bad as it was at the beginning.

But it's still a little unbearable, so hundreds of years have passed.

Su Zixuan has also successfully refined to as many as one hundred and fifty acupuncture points, and it is not far from those one hundred and eighty.

It may also be the reason why Su Zixuan has already adapted, and he is not so resistant, and even a little bit of enjoyment.

The pure black-red magic yuan power flowed into the meridian skin little by little along with the skin.

Su Zixuan also clearly felt the expansion of his muscles and veins, which he hadn't experienced for a long time!

After careful experience, he also felt that his ability to absorb the power of the Demon Yuan was also much stronger now.

"So...... It's a lot of time saver!"

Su Zixuan thought so.

After thinking about it for a while, he didn't think much about it, so he continued to take out the Demon Yuan Stone and began to cultivate quietly.

Thousands of years have passed, and Su Zixuan's body is already covered with dust, and the residual powder of the Demon Yuan Stone on the ground is also thickly piled up layer after layer.

"It looks like we've reached the limit!"

Su Zixuan looked inwardly and found that there were already one hundred and seventy-nine acupuncture points in his body that had been cleansed, and the last one, but they were like stubborn stones that could not be broken for a long time.

"Boy, you're fast enough, okay, don't continue, get out of the customs!"

"With your current ability, even if you face some people in the True Immortal Realm, you have a glimmer of hope of escaping, and if you fight hard, you should be able to kill those people, of course, it's better to be careful!"

"Yes, I understand that now Xiaoyu has also woken up, and I believe that there is still a chance for self-preservation!"

"Well, that's right!"

Then Xuzun's voice disappeared into Su Zixuan's mind.

In the past thousands of years, Su Zixuan has cultivated all the exercises again, and with the blessing of the Demon Yuan Force, its power is naturally incomparable.

He was also confident now that if he faced the three great ancestors of the underworld again, he could completely wipe them out with almost a single face.

But in the face of the immortals of the real true immortal realm, he still doesn't know if he has a chance, after all, he has not really seen those rumored true immortals yet.

After thinking about it, he changed to a new outfit, and at this moment, his hair also changed dramatically because of the introduction of the Demon Yuan Force, and once he used the Soul Devouring True Demon Skill, it would turn into a thick black and red color.

Under normal circumstances, it is a dusty silver-white color.

As the formation withdrew, the sound of breaking the air suddenly rose for a while, and Su Zixuan flew towards the north.

Now that he has enough magic yuan power, Su Zixuan's flight speed is also much faster, and he can also feel the fluctuating aura of a monk.

I guess it's almost there!

A few years later, on a giant peak, after Su Zixuan opened the Void Eye, a golden light shot straight out of it.

"Well, that's right, there should be a city in front, because there is a huge plaque hanging on the tower of that city, with the words Fengxian City written on it!"

"Huh, that's kind of interesting over there!"

Su Zixuan looked towards a fairy-like valley again, and couldn't help but laugh.

"Fenghua Valley!"

"This is probably a place where some scattered cultivators gather, it's better to go to this valley to stay and have a look, and it's not too late to go to that Phoenix Immortal City!"

Now that he had made a plan, Su Zixuan flew directly over there!
