Martial Arts Immortal.

Chapter 600 Key
In the dark void.

Lin Zheyu's figure flashed by.

Suddenly, his expression changed slightly and he looked behind him where he had just been.

Discovered?

Lin Zheyu was a little surprised.

The last time I entered the forbidden area, it took a long time before I was discovered.

And now, Lin Zheyu left as soon as he came in. He didn't expect to meet a strong man nearby.

Boom!

Just when Lin Zheyu was surprised.

A horrifying roar came from deep within the forbidden land.

Lin Zheyu's running figure suddenly stopped and looked towards the depths of the forbidden land.

"what is that?"

Lin Zheyu narrowed his eyes slightly, and countless martial arts divine patterns flashed in the depths of his pupils.

Because it's too far away, I can't see it clearly.

Lin Zheyu could only vaguely see that a huge hole had been torn open in the sky above the forbidden land.

A huge and terrifying phantom, like a god or demon, fell from the hole in the void.

Along with the phantom, a terrifying world like hell also fell.

"The Holy Church of Pain?"

Lin Zheyu felt a familiar breath.

Although he couldn't see it clearly, he couldn't help but think of the Holy Church of Pain because of the vague and familiar aura.

When I was fighting with Ji Wuxiang, Fensheng and Gui Ji, these guys exuded this kind of aura.

Boom!

Another wave of terrifying energy came.

But this time, it came from a different direction.

Lin Zheyu turned his head suddenly and looked in the direction where the energy fluctuations came from.

There, a shocking battle was also taking place.

I saw a silver-white sword light breaking through the darkness. Even from tens of millions of miles away, I could feel the terrifying aura emanating from the sword light.

"No wonder I was discovered by the strong men in the forbidden land right after I came in..."

Lin Zheyu suddenly realized.

The battle in the outside world affected the forbidden land and stirred up the situation in the entire forbidden land.

It was normal for strong people to gather from all directions and pass by the direction where Lin Zheyu was just now.

However, what made Lin Zheyu curious was.

In the several shocking battles going on now, are those guys fighting from the outside world all the way to the forbidden land, or are they breaking out directly in the forbidden land?

The thought flashed past.

Lin Zheyu suppressed his curiosity, moved slightly, and rushed away in another direction.

Having just escaped from the hands of the strongest men from three forces, Lin Zheyu doesn't want to fight with anyone else.

It is really frustrating to fight with these top powerhouses now.

Lin Zheyu has a clear understanding of himself.

The deficiency in his realm restricted his ability to display his strength. The most important thing for him now was to improve his realm as quickly as possible.

Rumble!
The roar of battle continued to be heard.

Lin Zheyu pushed his perception to the extreme, trying his best to avoid the strong people who might appear in the forbidden land.

His body moved quickly, and his martial arts eyes observed the void around him, looking for a weak area suitable for leaving.

More than three hours later.

Lin Zheyu stopped and punched into the void in front of him.

Unparalleled power burst out, causing terrible ripples in the void, and finally it exploded.

A huge hole suddenly appeared in the void, and terrible void turbulence surged on the opposite side.

Lin Zheyu's figure swayed slightly, and he disappeared into the turbulent flow of the void.

"what?!"

"Forbidden Mountain!"

Lin Zheyu suddenly exclaimed in surprise.

Just as he left the forbidden land and the hole in the void slowly closed, he vaguely saw a huge mountain pressing down from the void.

He was very familiar with that mountain.

It was the forbidden mountain where Wei Xiyao performed sacrifices.

Looking at the completely closed void passage, Lin Zheyu shook his head slightly and suppressed the curiosity in his heart.

Wei Xiyao is quite strong, there is no need to worry about her.

chi chi-

The terrifying turbulence of the void surged and bombarded Lin Zheyu, corroding his body and making a series of hissing sounds.

Lin Zheyu withdrew his gaze and observed the void around him.

He had been here once, so he had experience the second time.

sizzle-

Lin Zheyu's mind moved slightly, and the majestic power of the origin of thunder and lightning surged out, and terrifying thunders wandered across his body.

"there……"

Lin Zheyu looked towards the front left, moved slightly, and rushed towards that direction.

More than two hours later...

boom!
A terrifying roar was heard in the void.

A huge crack appeared with a hiss.

On the other side of the crack is a vast ocean formed by endless thunder.

Relying on the power of the origin of thunder and lightning and the special connection with the core origin land, Lin Zheyu found the passage to the origin space of thunder and lightning.

Zizzizi~~~
Terrifying bolts of lightning moved across Lin Zheyu's body.

These thunders contained terrifying destructive power, but did not cause any harm to Lin Zheyu.

On the contrary, the powerful vitality and power of creation contained in the thunder was slowly nourishing his body.

"I will stay here in seclusion for a while first. After I have accumulated enough source power, it won't be too late to go to the secret realm of the Four Elephants Divine Beasts."

Lin Zheyu looked around and saw nothing but an endless sea of ​​thunder.

This is a good place for retreat and cultivation.

If Meng Tianqing and the others are really ambushing him in the secret realm of the Four Divine Beasts, then let them wait.

Lin Zheyu didn't believe that such powerful people as the Holy Mother of Fire Spirit and Meng Tianqing would be so idle that they would wait aimlessly.

Thinking like this.

Lin Zheyu moved slightly and went towards the depths.

The deeper you go, the more terrifying the power of the thunder tribulation inside becomes.

Suddenly.

Lin Zheyu's expression changed slightly and he looked in the direction thousands of miles away.

"Is there anyone going through the tribulation?"

There was a hint of curiosity in Lin Zheyu's eyes.

In his perception, an endless supply of power from thunder and lightning gathered from all directions in the west, gradually condensing into a core of thunder and lightning. This thing would only condense when a strong person was going through the tribulation.

It was the first time that Lin Zheyu saw the condensation process of the core of the thunder tribulation.

His body moved slightly, and he instantly appeared next to the core of the thunder tribulation that was condensing.

The martial arts heavenly eye is pushed to the extreme.

Infinite martial arts divine patterns flowed in his deep eyes, constantly analyzing and deducing.

The gleam in Lin Zheyu's eyes became brighter and brighter.

"Is this the process of condensing the core of the thunder tribulation..."

"It actually contains the astonishing secrets of the universe and the void. It is truly amazing..."

Lin Zheyu murmured softly.

From the process of condensing the core of the thunder tribulation, he realized the mysteries of the universe and the void.

Although cultivators who practice the Four Origins mainly cultivate one origin, if they want to continue to improve their strength, they need to constantly deepen their understanding of the void of the Four Origins and further improve their own void domain.

However, Lin Zheyu was not very clear about the origin of thunder tribulation, how to construct a void field based on the origin of thunder tribulation after the origin was perfected, and how to improve it subsequently.

He grew up too fast and knew too few strong people.

Lin Zheyu didn't even know whether there was a strong person who could cultivate the origin of thunder tribulation and advance to the level of Cave Void Realm.

If this thing has not been passed down, you will need to comprehend and explore it on your own, which will take a lot of time and energy.

And now.

Lin Zheyu glimpsed a clue from the process of condensing the core of the thunder tribulation.

……

The cultivators in the outside world who are undergoing tribulation are not very strong.

The core of the thunder tribulation condensed very quickly, and it was almost formed in just a few breaths.

Lin Zheyu's expression changed slightly, and he began to imitate the condensation process of the core of the thunder tribulation.

He planned to try and see if he could condense a core of thunder and lightning in the void field within his body.

Zizizizi—the vast power of the origin of thunder came from all directions in the west. Lin Zheyu seemed to have turned into a black hole, madly devouring the power of the origin in the void.

In the void realm composed of mysterious void.

The majestic power of the origin of thunder and lightning penetrated from the void and converged towards a certain point.

sizzle-

The power of thunder and lightning continued to surge towards a certain point, and the original power of thunder and lightning contained in it became more and more terrifying.

The void around that point was rippling.

The void seemed to have become a canvas, gradually collapsing, unable to bear the terrifying weight contained in that one point.

Boom!

Suddenly, that point exploded violently, blasting a huge hole in the void.

Lin Zheyu spat out a mouthful of blood and his face turned pale in an instant.

"No, if you want to condense the core of the thunder tribulation, you need to have a deeper understanding of the universe from the perspective of the origin of the thunder tribulation."

"but……"

"It's too dangerous to try in the void realm. Don't be so reckless next time."

Lin Zheyu shook his head slightly, and his pale face slowly turned rosy again.

His void realm is constructed based on the mysterious void.

The mysterious void is closely related to the physical body.

Lin Zheyu's physical body is so powerful, and the void field constructed based on the mysterious void is also extremely stable.

Under normal circumstances, ordinary explosions are unlikely to affect the void realm.

What Lin Zheyu didn't expect was that the explosion of the core of the thunder tribulation was so powerful and had such a great impact on the void realm.

And this is just a failed product condensed by Lin Zheyu!
However, this is also related to the fact that the core of the thunder tribulation that Lin Zheyu just tried to condense contained relatively strong power.

"The core of the thunder tribulation can transmit the power of the thunder tribulation across countless dimensional voids and bring down the thunder tribulation. It contains extremely special secrets of the universe..."

"No wonder it has such a destructive power on the void realm."

"If we can master the method of condensing the core of the thunder tribulation, it would be a powerful means."

Lin Zheyu said with a smile.

He glanced at the core of the thunder tribulation.

The core of the thunder tribulation has been completely formed. The one undergoing the tribulation should be a Nascent Soul cultivator. The aura emitted by the core of the thunder tribulation is extremely weak.

Lin Zheyu could crush it with just a flick of his hand.

It is difficult to gain any useful insights from the core of the thunder tribulation that has already condensed into a solid form.

Lin Zheyu smiled and ignored the core of the thunder tribulation.

He simply sat cross-legged aside and began to practice.

The core origin land is so large that it doesn't matter where you practice.

Lin Zheyu breathed out softly and concentrated.

The Martial Arts Heavenly Eye opened from the sea of ​​consciousness, was stimulated to the extreme, and began to study its own mysteries.

Lin Zheyu had just made some discoveries when he was interrupted by Bing Ji and the others.

Now, while I am accumulating source power, I can take this opportunity to study the secrets contained in my physical body.

Martial arts cultivate the body.

The physical body is the foundation of martial arts.

Only by thoroughly studying the mysteries contained in the physical body can one go further in martial arts.

As the number one person in martial arts, he had no reference in the classics and documents left by his predecessors on his subsequent journey of martial arts.

From now on, Lin Zheyu can only rely on himself to explore.

Time passes slowly.

More than ten days later.

Lin Zheyu suddenly opened his eyes, and his aura returned to its peak in an instant.

He let out a breath and glanced at the data in his mind.

Source power, 20 more units.

"too slow……"

Lin Zheyu sighed softly.

A long time ago, he could gain 20 units of source power by practicing the "Extreme Method" once.

Now that the strength has increased so much, it is still 20 units of source power.

The further you go, the more difficult it becomes to obtain source power.

I don't know what level of strength I need to improve to the next time I get more source power...

Could it be comparable to the He Dao?
Lin Zheyu muttered to himself and shook his head slightly.

All he can do now is to continuously optimize the "Extreme Method" and improve the efficiency of obtaining source power.

However, the source power obtained did not increase.

But if one condenses the extreme energy and uses it for cultivation, the extreme energy will increase a lot as Lin Zheyu's strength improves.

Get rid of distracting thoughts in your mind.

Lin Zheyu continued to study the mysteries of the physical body.

The transformed martial arts eye was much more powerful than the original spiritual eye. In just over ten days, Lin Zheyu had made considerable gains.

The Martial Arts Heavenly Eye opened, and in the depths of the pupils, countless Martial Arts divine patterns kept flowing.

From the perspective of the Martial Arts Heavenly Eye, a series of mysterious connections were established between the three great divine voids and the void realm formed by the mysterious void.

Not only the three great divine treasures are in the void.

Even the connections between the internal organs, acupoints, meridians, etc. and the void realm are outlined.

"The human body is indeed a special universe..."

"Although there are significant differences between this world and the outside world, in essence, they share something in common..."

"The three great divine treasures are the core source of the land, and they are the basic energy that breeds the origins of various great ways..."

"..."

Lin Zheyu's mind raced, and a steady stream of inspiration emerged.

As his understanding of the physical body deepened, he became more and more convinced that the human body is a special universe.

Rumbling--

The vast energy of qi and blood is flowing wildly in the body.

Lin Zheyu tried to deepen the connection between the void realm and the three major divine treasures, the five internal organs, the acupoints throughout the body, and so on.

after one day.

Lin Zheyu suddenly opened his eyes and his figure suddenly disappeared.

The vast ocean transformed from thunder surged, gathering from all directions and rushing madly towards a certain point in the void.

Someone else has started to overcome the tribulation.

As the catastrophe approached, the frequency of cultivators undergoing the tribulation increased, and Lin Zheyu could often sense the core of the thunder tribulation condensing.

At first he went there out of curiosity to comprehend and study.

In the end, the thunder tribulation was too weak, and the condensed thunder tribulation core could no longer attract any interest from Lin Zheyu.

It must at least be comparable to the thunder tribulation of the God Transformation, and the condensed thunder tribulation core can arouse some interest in Lin Zheyu.

"The lightning core condensed this time is very powerful!"

Lin Zheyu looked at the core of the thunder tribulation that was condensing and said with some surprise.

In a moment, its power was comparable to that of a god.

And it is still soaring at an astonishing speed.

"This doesn't seem to be the thunder tribulation caused by a realm breakthrough..."

Lin Zheyu's expression changed slightly as he noticed some differences in the core of the thunder tribulation that was condensing.

However, no matter what kind of thunder tribulation it is, it will not affect Lin Zheyu's perception of the mysteries of the universe and the void contained therein.

sizzle-

The core of the thunder tribulation continues to condense.

And in Lin Zheyu's palm, there was also a weak thunder core that was slowly condensing.

His ambition was too great before, which led to the failure of cohesion.

Later, Lin Zheyu started from the weak thunder tribulation core and slowly increased the power of the thunder tribulation core.

"It has form but not spirit. What is missing?"

Lin Zheyu comprehended the core of the thunder tribulation that was condensing, then frowned and looked at the weakened version of the thunder tribulation core in his palm.

This was the result of his contemplation of the core of the thunder tribulation over the past ten days.

But it seems a little unsatisfactory.

After leaving the void realm, the condensed thunder core will not have such great destructive power.

Among these, there should be a lack of extremely critical factors related to the void realm.

But Lin Zheyu still hasn't figured out what it is specifically.

"Does it have to be tried in the void realm?" Lin Zheyu couldn't help but have this thought.

After the first injury experience, Lin Zheyu never tried the void realm again.

"Then let's try it..."

"The core of the condensed lightning tribulation is a bit weaker, so it shouldn't be a big problem..."

……
