Chapter 298: Who is calling me?

Swish!

In the blink of an eye.

Lin Yuan and Xi Lan arrived at the second transit planet.

"This spatial passage—"

Lin Yuan looked back and said in surprise, "Establishing such a stable spatial passage must require a significant price, right?"

Spatial passages are very easy to open up.

An ordinary Eighth-Order Evolver at the Peak has the ability to open them up.

When Lin Yuan broke through to the sixth tier, Senior Brother appeared, intending to bring Lin Yuan back to the Crimson Kun Main Star. The crystal Rubik's cube he crushed immediately opened a spatial passage leading to the Crimson Kun Main Star.

The truly difficult part of a spatial passage lies in its stability and maintenance.

Especially the latter; the crystal Rubik's cube manufactured by Red Kun Star Lord consumed a lot of energy. Even so, the spatial passage ultimately opened only maintained for two minutes?

The Main Universe itself has the ability to recover. Unless it is caused by a Supreme Powerhouse level creating permanent spatial rifts, any other spatial fluctuations will slowly recover to their original state.

Therefore——

To maintain a stable spatial passage for a long time, energy support must be provided every moment.

This is also the reason why spatial passages are only popularized in the Central Star Region. Wanting to widely popularize and maintain them within the Human Civilization territory would require too high a price.

Of course, in an emergency, such as a battlefield breaking out and alien races having already invaded the Human Civilization territory, with the methods of Human Civilization, stable spatial passages can be instantly established across the entire Human Civilization territory.

"Yes, because no fees are collected, the cost of maintaining the spatial passages is entirely borne by Human Civilization."

Xi Lan said.

Outside of the Central Star Region, private spatial passages might exist in other star sectors or star alliances. If one is unwilling to travel, they can pay a high price in civilization coins to make use of that spatial passage.

Swish!

Swish!

Swish!

After passing through dozens of transit planets…

Lin Yuan and Xi Lan finally arrived at the mother planet.

"Is this the mother planet?"

Lin Yuan carefully looked around.

The mother planet is very small, its size incomparable even to ordinary medium-sized living planets. However, because it is the birthplace of Human Civilization and possesses a special status, it is now a political center in a certain sense.

Many special heavy and ultimate treasures, such as the twelve-star cosmic rare treasure "eternal spring", etc., are placed on the mother planet.

Because the mother planet is not large, anyone wanting to enter must undergo layers of strict reviews.

On the mother planet, the people you casually brush past might very well be ninth-order or Tier 10 Evolvers.

Of course, regardless of the level of the Evolver, while on the mother planet, it is forbidden to emit any aura. Even an Eleven-Tier Evolver must obediently walk on foot when it is time to walk.

"The location of the eternal spring is at 'Green Mountain Peak' on the second continent. I do not have the authority to go deeper, Galaxy Star Master, you can go over by yourself."

Xi Lan escorted Lin Yuan for a while, stopped, and said.

"Alright."

Lin Yuan nodded.

Along the way, Xi Lan had long since informed him of the detailed map of the mother planet and some taboo matters. As a ninth-order Evolver, understanding and absorbing them was just a matter of an instant.

Now Lin Yuan's familiarity with the mother planet was no less than that of the Galaxy Main Star.

Before parting.

Xi Lan suddenly remembered something and asked, "Galaxy Star Master, the 'Profound Yellow' Secret Realm is about to open soon, are you interested in going in to explore?"

"Profound Yellow Secret Realm?"

This was not the first time Lin Yuan had heard of the 'Profound Yellow' Secret Realm; earlier, his teacher Red Kun Star Lord had also mentioned this matter when looking for him.

Furthermore, the 'Profound Yellow' evolutionary pathway that Lin Yuan practiced concurrently also had a massive connection with the 'Profound Yellow' Secret Realm.

"About when will it open?"

Lin Yuan asked.

"In about half a year," Xi Lan replied.

"At that time, many of our human Evolvers will go in to explore, and at the same time, other alien races will also enter."

Xi Lan said.

The 'Profound Yellow' Secret Realm is not a cosmic Secret Realm controlled by humans.

Other alien Experts can also enter.

As a result… the most dangerous part of entering to explore is not the Secret Realm itself, but the other alien races.

Human Civilization and those alien races have fought for I don't know how many years, and their hatred for each other runs as deep as the sea. If they meet in the Secret Realm, unless there is another greater threat, they will most likely make a move against each other.

"Understood."

"I'll see when the time comes."

Lin Yuan nodded.

Regarding the 'Profound Yellow' Secret Realm, Lin Yuan was indeed somewhat interested. The 'Profound Yellow' evolutionary pathway he practiced concurrently came from there.

Although the 'Profound Yellow' evolutionary pathway only had the first half, stopping at the Eighth-Order, through comprehending the first half, Lin Yuan determined that this evolutionary pathway had tremendous potential.

It was almost no worse than the Immortal Cultivation system of the Spirit Realm, and the Immortal Cultivation system, explained in the words of the Main World, was a supreme evolutionary pathway, and a supreme evolutionary pathway with an Ultimate Existence.

Soon.

Lin Yuan followed the fixed passage and came to 'Green Mountain' on the mother planet.

"Green Mountain Peak."

Lin Yuan climbed up the mountain path.

"Is this Green Mountain also a treasure?"

Lin Yuan's expression was thoughtful.

Green Mountain Peak.

Through layers of identity verification, Lin Yuan finally arrived before the eternal spring.

This twelve-star cosmic rare treasure looked on the outside like a white pool more than ten meters in size.

Milky-white spring water continuously gushed out from the central area of the pool.

Even just looking at it like this, Lin Yuan felt a pure and gentle force rushing towards him.

"The eternal spring contains the aura of eternity. All lives that have soaked in the spring water can prolong their Lifespan by at least 500,000 years."

Information about the eternal spring flashed through Lin Yuan's mind.

Prolonging Lifespan by 500,000 years. You must know that below the Supreme Powerhouse, the Lifespans of all Evolvers are limited. Even existences who have mastered the Time Rule can arbitrarily change the passage of time on their body surface, making only a single day pass for themselves while ten thousand years pass in the outside world.

But Lifespan will eventually be exhausted one day.

500,000 years—leaving aside Eleven-Tier Evolvers, for ninth-order and Tier 10 Evolvers, it might just allow them to take another step forward.

In addition, besides prolonging Lifespan, the eternal spring also had many wondrous effects on the Physical Body, capable of enhancing physical foundation potential and so on.

This was the foundation belonging exclusively to Human Civilization. Human Evolvers above the ninth-order had a limit Lifespan 500,000 years longer than Experts above the ninth-order of other groups.

It might not be obvious in a short time, but as the timeline is drawn out, the effect becomes very obvious.

It's just that the cost of activating the eternal spring is huge. For Human Civilization's own people, if they want to soak in the eternal spring, there are two pathways.

One is stepping into the ninth-order.

The second is consuming 5 million Merit Points.

Aside from these, there are no exceptions.

Once, a certain alien Supreme Powerhouse wanted to borrow the eternal spring to enhance the foundation for a junior they valued.

For this, that Supreme Powerhouse was willing to pay an eleven-star top-grade cosmic rare treasure.

Eleven-star top-grade. That was a cosmic rare treasure of the same level as the World Tree, each piece priceless and could be passed down as the group's foundation.

But in the end, it was still rejected by Human Civilization.

It wasn't that they looked down on the eleven-star top-grade cosmic rare treasure, but that they were unwilling to "aid the enemy".

The junior valued by that alien Supreme Powerhouse had huge potential and the hope of becoming a Supreme Powerhouse. If they gained another 500,000 years of Lifespan…

The possibility of taking that step would only be greater.

For an eleven-star top-grade cosmic rare treasure, allowing an alien race to potentially gain an additional Supreme Powerhouse, Human Civilization wasn't that foolish.

Even if this alien race had no direct conflict with Human Civilization, it was absolutely not allowed.

Human Civilization guarded against alien races that submitted and surrendered to it, as well as alien races within the Human Civilization Alliance, let alone others?

Those not of our race are bound to have different hearts.

"Begin, begin."

Lin Yuan put away the Eighth-Order armor and walked naked into the pool water.

The moment he soaked in the milky-white spring water, Lin Yuan felt a cool force blend into his body from his skin, rapidly spreading along his limbs and bones.

"This feeling?"

Lin Yuan carefully observed his own changes and found that every single cell was frantically devouring the spring water. In just a short moment, he noticed that his physical potential began to improve.

What is physical potential?

Whether it is an Eighth-Order Evolver or a ninth-order Evolver, the Physical Body has an upper limit and will not grow stronger endlessly. After approaching the limit, the speed of improvement will slow down and stagnate.

This is physical potential.

And the enhancement of potential meant that the physical strength could continue to rise, equivalent to breaking shackles, allowing strength to go a step further.

Lin Yuan's physical strength already far exceeded other normal humans. Under the blessing of the liquid in the Mysterious Gourd, it was fully a dozen times the original.

With such a high upper limit, improving it would only be more difficult, yet under the soaking of the eternal spring pool water, it actually began to slowly improve again.

"And Lifespan."

Lin Yuan narrowed his eyes slightly; he could sense that his Lifespan was beginning to extend.

Ten years.

A hundred years.

A thousand years.

Ten thousand years.

After each Evolver soaked in the eternal spring, the increased Lifespan was not uniform, depending specifically on the absorption and adaptation to the spring water, but at the very least, it could increase Lifespan by 500,000 years.

"As expected of a twelve-star cosmic rare treasure."

A smile appeared on Lin Yuan's face. No wonder Human Civilization grew so prosperous in just over two million years with such a rare treasure capable of increasing every Evolver's foundation and Lifespan.

Although the World Tree had many wonderful uses, its world fruit could help Evolvers open up their Internal World in advance.

But in terms of value, it was far less than the eternal spring.

After all, the World Tree itself could only be used by one Evolver, as for the world fruit, it only helped sixth-tier and seventh-tier Evolvers easily open up their Internal World.

But the eternal spring produced huge help for ninth-order and Tier 10 Evolvers.

"I wonder which has greater value, this eternal spring or that gourd of mine?"

Lin Yuan thought to himself while soaking in the eternal spring.

Ever since he obtained the Mysterious Gourd, he had never figured out its background, and searching through all the data banks of Human Civilization yielded no similar information.

"Far from it."

Lin Yuan's expression began to grow solemn.

The "far from it" here meant that the eternal spring was far inferior to the Mysterious Gourd.

The eternal spring could enhance physical potential foundation and prolong Lifespan by 500,000 years.

But these… compared to the Heaven-Defying effects of the Mysterious Gourd, were simply nothing.

The eternal spring could only enhance physical foundation, but the Mysterious Gourd could directly strengthen the physical upper limit. Theoretically, after absorbing all seven types of liquid, the physical amplification would reach 23.31 times.

And the amplification here was a foundational amplification, not just increasing a fixed strength.

As for prolonging Lifespan, it indeed had great use, but compared to the Internal World's foundational size directly surging by 23.31 times, it was once again completely outclassed.

The importance of the Internal World's size to Eighth-Order Experts was self-evident. Increasing it by a hundred miles could possibly raise strength by a notch, let alone increasing it by 23.31 times?

As for reaching the ninth-order and Tier 10.

Although they began to expand the depth of the Internal World—that is, opening up layer upon layer of spatial layers.

But the original size of the Internal World was similarly the foundation.

An Internal World with a radius of 100 million miles, even with only ten spatial layers, could crush ninth-order Experts with a thousand or several thousand spatial layers.

"I must protect my gourd well."

Lin Yuan's heart tightened.

If the eternal spring was already a twelve-star cosmic rare treasure, what grade was the Mysterious Gourd that completely defeated the eternal spring? Thirteen-star?

Time slowly passed.

In the blink of an eye, half a year passed.

For any newly entered ninth-order Evolver, the time to soak in the eternal spring was limited to half a year.

Any longer, the effect of the spring water on oneself would rapidly decrease, making it meaningless.

"It's about time."

Lin Yuan stood up and actively walked out of the white pool.

"My physical potential has improved by about 80%, as for Lifespan? 700,000 years?"

Lin Yuan was in a good mood.

Although Lifespan had no meaning to him, relying on Heaven-Defying Comprehension, Lin Yuan couldn't possibly break through right at the edge of his Lifespan limit.

But as for Lifespan, no one would think it too much.

Stepping out from the eternal spring, Lin Yuan was arranged into a room.

Newly entered ninth-order Evolvers, besides being able to soak in the eternal spring once, could also stay overnight at Green Mountain Peak, right next to the eternal spring after soaking.

Inside the room.

Lin Yuan rarely did not Cultivate or comprehend the Dao.

Instead, he sat quietly there, feeling the mysterious aura flowing on the mother planet.

This mysterious aura was vast and profound. Even Lin Yuan, who could now treat stars as toys, felt as though he had returned to his mother's embrace.

"I heard that the Town-Clan Weapon of our Human Civilization is on the mother planet. This is also the reason why the mother planet and the entire Central Star Region have never been invaded by alien races for so many years."

Lin Yuan thought silently in his heart.

Relying on that Town-Clan Weapon, even if Supreme Powerhouses arrived in alliance, within the range of the Central Star Region, they would not gain any advantage.

They could only return in defeat.

This Town-Clan Weapon was the absolute foundation of Human Civilization.

The lair of any Peak Groups had the ability to restrict Supreme Powerhouses.

Otherwise, if Supreme Powerhouses wanted to come and go as they pleased, could they still be called Peak Groups?

"So comfortable."

Lin Yuan closed his eyes, casually feeling every little detail on the mother planet.

Suddenly.

At a certain moment.

From the depths of the distant starry sky, a vague and faint call crossed countless tens of thousands of light-years, establishing a connection with Lin Yuan in some mysterious way.

This call could only be detected by Lin Yuan; even the mother planet, the lair of Human Civilization, failed to capture it.

That Town-Clan Weapon, which constantly monitored all changes on the mother planet, likewise did not perceive the slightest bit of it.

Powerful Evolvers one after another on the mother planet—ninth-order, Tier 10, Eleven-Tier—all failed to discover any abnormalities.

Even the perception of Supreme Powerhouses constantly shrouding the mother planet still did not notice anything.

Everything had no changes.

Only Lin Yuan.

Only Lin Yuan felt that vague yet incomparably firm call.

"Who is it?"

Lin Yuan silently opened his eyes, looking towards the depths of the starry sky, which was the source of the call.

"Who is calling me?"
