The black tower is majestic, and although it only occupies a very small part of this mysterious area, the vast power it exudes is like the core of this vast and mysterious space.

Attracted Wu Yuan's full attention!

"It!" Wu Yuan's consciousness converged on the Black Tower, only to feel that the Black Tower was vast and extensive, containing endless majesty, but it also gave Wu Yuan a sense of cordiality and warmth.

It's as if the wanderer has returned to his hometown.

Wu Yuan quickly calmed down.

"This Black Tower, which I came into contact with in my previous life, is almost exactly the same from the appearance alone!" Wu Yuan couldn't help but recall some things in his previous life.

As early as the end of the 21st century, in the depths of the Blue Star, a relic of an ancient civilization excavated by the Human Federation revealed that there was an era in history when a group of extremely powerful and terrifying creatures known as 'standing up to the sky' were active...... As the years passed, the dust was buried, and countless traces were erased.

Only in the middle of that mysterious ruin, there is a black tower buried!

Intact!

Later, the 'Federation Life Technology', which originally encountered a technological bottleneck, began to make rapid breakthroughs, the ancient 'martial arts' began to revivenation, and human beings started a great leap in life after entering the interstellar era, and the limits of life were broken again and again.

It must be known that in the 21st century, the top Hercules among the Blue Star humans can only lift a thousand catties of gravity.

And when Wu Yuan rose.

The martial arts masters of the Human Federation all have tens of thousands of catties of power!

These are some of the Federation secrets that Wu Yuan only came into contact with after he became a 'Grandmaster' and entered the top martial arts circle!

Meantime.

As a martial arts master, he was also able to get close to the black tower that was more than 100 meters high, and finally tried to touch it with his own hands.

After touching it, there was no abnormality.

It wasn't until a few years later that Wu Yuan faintly found a way to break the limits of the human body...... He has traveled to the vastness of Middle-earth!

At the beginning of the crossing.

Wu Yuan was curious about how he crossed over.

He doesn't believe in any 'destiny', 'luck' and 'reincarnation', and firmly believes that everything has a reason and a source, and the same is true for his own crossing.

to this day.

After taking nine Condensing Pills in a row, his spirit grew to an astonishing extent, and his consciousness sensed the 'Upper Dantian Palace' in one fell swoop, and saw the 'Black Tower' in the Upper Dantian Palace.

He just guessed!

When you come to Middle-earth, you should be inseparable from the mysterious Black Tower.

"This mysterious and vast place should be the Upper Dantian Palace, the source of the gods and the place where they live." With a single thought, Wu Yuan was able to let his consciousness withdraw like a tide.

With one thought, the consciousness can sense this space again, and it completely pours in.

"The Black Tower in the Upper Dantian Palace is illusory? Only consciousness can 'see' it, and it cannot really touch it. Wu Yuan pondered: "There seems to be some difference between it and the Black Tower that I have touched with my own hands. ”

The Black Tower he had touched was full of majesty, and there was nothing else miraculous.

However, the black tower in the Upper Dantian Palace was extremely warm, making Wu Yuan feel 'warm' all over, and his consciousness was instinctively reluctant to leave.

"Black Tower!"

Wu Yuan's consciousness 'looked at the Black Tower from afar', only to feel that he was becoming more and more comfortable, allowing him to instinctively immerse himself in it, and only a trace of consciousness remained awake.

At the same time, wisps of invisible strange power surged from the Black Tower, making Wu Yuan's consciousness seem to begin to grow.

Strong!

The improvement of the divine spirit was very weak and almost imperceptible, but Wu Yuan was keenly aware of this change in the consciousness of the divine spirit.

"What's going on?"

"I didn't do anything, just meditatively 'watching' the Black Tower, and my spirit grew unconsciously?" Wu Yuan was stunned for a while, and then a thought came to mind: "Could it be that I was the legendary 'Divine Spirit Visualization' just now?" ”

Whether in previous lives or in Middle-earth, there are legends similar to 'visualization', and there are very few records in many ancient biographies.

The growth of the spirit, there are some natural treasures effective!

If your body is strong, you will also be pregnant and strong.

There is also a legend that contemplats thoughts!

"Entering the Dantian Palace, the gods live in it, you can observe the world and all the world, all the spirits in the world, the six desires of the red dust, and the seven emotions of the human heart...... Everything can be imagined! There will be many illusions in the process of visualization! In the end, it can be embodied as its own reality...... This is called the idea of the spirit of the gods. Wu Yuan recalled the large amount of cultivation information provided by the Human Federation in his previous life.

These messages were compiled by the Human Federation from many martial arts sect classics and civilization relics, and they were very detailed.

It's just that the authenticity has not been verifiable.

Because, at that time, the Human Federation, there was no martial arts master who could open the Upper Dantian Palace, how could he contemplate it?

In other words, even if someone succeeds in contemplating, I am afraid that it is the highest secret of the Human Federation.

It's not something that Wu Yuan can touch!

"Back then, I thought that the so-called relics of civilization and the Black Tower were just scams, so I didn't think much about it." Wu Yuan pondered quietly: "Looking at it now, there is a mysterious black tower, and there are also a group of terrifying existences that may exist in history...... The world in which the Human Federation is located is not as simple as I imagined. ”

Middle-earth, full of mysteries!

Wu Yuan couldn't help but think of what Gao Yu said'Immortal Family Ruins', it seemed that everything was expounding, and many things were not as simple as he imagined!

"I haven't really seen the contemplation of thoughts, but I understand some of them quickly, whether it is contemplating the 'Hell Assura' or the 'Ascension to the Heavenly Palace', or the 'Splendid Mountains and Rivers', there is no essential difference, every time the spirit grows stronger, it will experience many dangers and sink into it." Wu Yuan said secretly: "But I unconsciously contemplated this 'Black Tower', and I didn't encounter a trace of danger. ”

This moment.

Wu Yuan did not know whether the information he knew was true or false.

I don't know if I'm really visualizing.

"But one day I can confirm that when I 'look' at the Black Tower, my spirit is indeed growing." Wu Yuan grasped the point.

Everything else is false, and only the growth of the spirit is real.

As for the Black Tower in the Upper Dantian Palace?

"Whether it is beneficial or harmful in the end, now I have just opened the Upper Dantian Palace, and I have no ability to help it at all." Wu Yuan's heart is very wide: "What I have to do now is to continue to strengthen myself, so that I can hope to explore the secrets behind it in the future." ”

"And 'visualizing the Black Tower' can continue to strengthen the gods without harm, which is a special opportunity!"

Spirit, ethereal, is difficult to grow by conventional methods.

And it doesn't seem to be directly useful for martial arts battles.

However, when the spirit grows, the wisdom and understanding will increase, and the speed of the mind will be strong.

Whether it is the control of physical fitness, or the cultivation of 'combat skills', it will achieve twice the result with half the effort!

"Go on."

Wu Yuan continued to 'visualize' the black tower in the Upper Dantian Palace, and his spirit continued to grow, although the improvement was small.

It can accumulate silicon for thousands of miles.

Small improvements, added up over time, will be a great achievement that is jaw-dropping.

Time passes!

As the 'visualization' continued, Wu Yuan's consciousness was completely silent, and he began to blur unconsciously.

Suddenly.

"Huh?" Wu Yuan only felt that his spirit was slammed, and his consciousness seemed to be about to collapse, and endless darkness was coming, and he was about to fall into a deep sleep.

Wu Yuan suddenly understood that contemplating the Black Tower was not infinite, and it would make the spirit tired.

It's like quenching the body, you can't exceed the upper limit of the body's tolerance.

You have to rest.

And the best way to recuperate is - sleep!

…… This night, Wu Yuan slept very deeply, dreamless, as if he opened his eyes again as soon as he closed them.

"Whew!" Wu Yuan turned over and got up, only to feel refreshed, and his spirit was so powerful that he didn't know how much stronger than before taking the Concentration Pill.

With a single thought, you can easily perceive any part of the surrounding environment, and you don't need to meditate on it as before!

One thought can perceive the very subtle layers of the body's muscles, bones, flesh and blood, far beyond the ordinary 'inner vision'.

As soon as I thought about it, I felt more clearly the Upper Dantian Palace located in the brain!

The black tower, which seems to be unchanged, hangs in it, surrounded by a blood-colored air flow that is so thin that it is faintly visible.

"Visualize." As soon as Wu Yuan tried it, he felt a burst of pain in his spirit, as if it was about to explode.

It made him understand.

You have to wait until your mind is completely healed before you can visualize again.

"The blood-colored mist on Nata's body...... It seems to be the strange energy that was previously integrated into the limbs of the body. Wu Yuan sensed the blood-colored mist and distinguished it.

He tried to induce the blood-colored mist.

But it seems to be too thin, they surround the Black Tower, and with Wu Yuan's power, they can't be attracted at all.

"Is there only so much of this blood-colored mist?" Wu Yuan pondered secretly.

If he talks about the Black Tower, he still knows a little about it.

How did this mysterious blood-colored mist come about? What is it used for? Will there be any side effects? He didn't understand it at all.

It can only be changed with the same.

"Take your time, I've just opened the Upper Dantian Palace, just visualizing the Black Tower's growth of the spirit, it's extremely rare!" Wu Yuan was not in a hurry to figure everything out.

Going to the Dantian Palace involves the root of life, and it must not be careless.

"Wow~" The consciousness withdrew from the Upper Dantian Palace like a tide, and Wu Yuan's eyes swept around, and he could see the bright light shining through.

The martial arts hall lit up for a long time.

"I visualize once, how long has it been?" Wu Yuan said secretly, and suddenly felt that his stomach was 'growling'.

Somewhat hungry!

Bang ~ The door of the palace opened, the sky outside was bright, and there was no one, only Gu Ji was still sitting cross-legged in the pavilion.

"Childe." Gu Ji got up and said softly, "How?" ”

"Something works!" Wu Yuan said vaguely: "Uncle Ji, when is it now?" How long have I been in retreat? ”

"Is it just useful?" Gu Ji sighed in his heart, and said on the side: "Since the first time you entered the martial arts hall, Gongzi, you have been in retreat for a total of six hours. ”

Six hours?

Wu Yuan understood after a little calculation that it took about three hours for him to visualize the Black Tower once!

It was something he had to figure out.

"Uncle Ji, I'm a little hungry, let's go eat first." Wu Yuan said and walked directly to the inner house.

The maid who had arranged her own arrangement brought the meal.

……

For several days, Wu Yuan continued to practice the "Tiger and Leopard Bone Cultivation Technique" with the 'spiritual liquid', trying his best to improve his physical fitness to the current limit.

On the other hand, every once in a while, I try to visualize the Black Tower to see when the spirit will fully recover.

Eight days.

Wu Yuan was finally able to confirm that each visualization would take about three hours, and that he would have to wait more than four days before he could visualize again.

As for the bloody mist? Wu Yuan still hadn't figured it out.

On this day, he came out of the Yanwu Hall again.

"Uncle Ji, don't delay, we'll leave for Nanmeng Martial Academy tomorrow." Wu Yuan said softly.
