Nuclear-powered Sword Immortal-Chapter 637 - 622 Testing the Machine_2

Ye Yan couldn’t help but shake his head as he spoke.

"Devoured by that Evil God..."

Gu Jinlai also felt some regret, "I originally wanted to know how the Profound Immortal Realm managed to crush that terrifying Evil God back then, and whether we can replicate that success if the Evil God reemerged. Now it seems... we might not get an answer."

"Replicate that victory? There’s hardly any chance."

Ye Yan said, "Back then, with abundant spiritual energy, our Profound Immortal Realm maintained close connections with neighboring realms through Realm Gate technology, exchanging knowledge and progressing together, our combined strength even greater than now. But since the decline of spiritual energy ten thousand years ago, almost all connections between the realms have ceased."

As he said this, the corner of his mouth twitched, "Operating a Realm Gate consumes too much energy, even more than activating the Heavenly Dao. Now, only the Xuanyuan Sword Sect can barely support this kind of expenditure."

Gu Jinlai had already been in the Profound Immortal Realm for most of the year.

Especially in the past few months, wandering in the mortal nations away from the Spirit Veins, he clearly felt how scarce the spiritual energy was in those mortal nations.

"It’s said that scholars from the Xuanyuan Sword Sect have claimed that if we can’t find a way to halt the decline of spiritual energy, it’s estimated that in another eight to ten thousand years, the Profound Immortal Realm will become completely unsuitable for cultivators to live in, everyone’s Spirit Roots will devolve, and at most people can achieve something in Martial Arts... Immortals, will become extinct from the world."

Ye Yan’s eyes were full of concern, "Over a decade ago, the Chi Family accused the Xuanyuan Sword Sect of intending to establish a Super Grotto Heaven spanning tens of thousands of miles, incorporating all the Spirit Mechanisms of the Profound Immortal Realm into this Super Grotto Heaven to ensure the circulation of spiritual energy, survive the period of spiritual energy extinction, and wait for the day it might recover. Although the Xuanyuan Sword Sect has denied this, if it is true... it’s likely all forces in the Profound Immortal Realm would start building their own Super Grotto Heavens just in case."

After speaking, his expression turned extremely grave.

Gu Jinlai knew the reason behind his solemn expression.

If it came to that step...

All existing rules of the Profound Immortal Realm would be shattered.

All the top forces in the struggle for Spirit Mechanisms might plunge the entire Profound Immortal Realm into an abyss of war.

"Forget it, let’s not borrow trouble."

Ye Yan waved his hand, "Eight thousand years, ten thousand years, it’s still far away from us. Even the Heavenly Immortals won’t live to see that time, and those of us who are True Immortals will probably have died long before that, our Divine Sense collapsing under the weight of time’s sediment."

Gu Jinlai nodded, deciding not to continue on this topic.

Just then, the Creation Heaven Dao above the Sky Dome of Creation Grotto Heaven surged rapidly, all its radiance converging upon Jiang Yujian, covering him in a brilliant glow.

When the light faded, Jiang Yujian emerged from within, his aura nearly completely integrated with the Creation Heaven Dao.

"Success."

Ye Yan couldn’t help but smile.

"The Creation Heaven Dao."

Gu Jinlai was somewhat anticipatory.

Jiang Yujian, within the Creation Heaven Dao, seemingly found it quite novel and, after adjusting for a moment, took a weightless step and appeared beside Gu Jinlai and Ye Yan.

"Master, Third Brother, I’ve kept you waiting."

Jiang Yujian said, his mood uplifted.

"Don’t mention it, you’ve finally mastered the Creation Heaven Dao, and now I can retire with peace of mind."

Ye Yan said, "The most important thing in the cultivation from True Immortal to Heavenly Immortal is to integrate one’s own Dao Fruit into the Grotto Heaven and become one with it. We have a Grotto Heaven, and even the Heavenly Dao required for the second step of Heavenly Immortal Daoist Master. What you need to do next is to continually hone your Divine Thought, to undergo the Transformation required to sustain the resonance between the Dao Fruit and the Grotto Heaven."

"I understand."

Jiang Yujian nodded gravely.

During this time, Gu Jinlai had learned about the stages of True Immortal, Heavenly Immortal, and Profound Immortal by reading books.

From True Immortal to Heavenly Immortal is the process of integrating one’s Dao Fruit into the Grotto Heaven.

For ordinary True Immortals, the most critical step is actually building the Grotto Heaven. This is why many forces consider the Grotto Heaven the foundation of their Sect.

Without exaggeration, the number of Grotto Heavens a Sect has signifies how many Heavenly Immortals it might potentially nurture in the future.

Well...

That doesn’t include the top-tier resources of the Longevity World, where even Void Immortals could easily create a Grotto Heaven.

Once True Immortals have a Grotto Heaven, they need to integrate their Dao Fruit into it, at which point they and their Grotto Heaven become nearly an entirety.

This is also why Heavenly Immortals are known as Cave Heaven Immortals.

However, merging the Dao Fruit with the Grotto Heaven is not an easy task.

Cultivators must possess a powerful enough Divine Thought to support a Grotto Heaven.

In fact, whether it’s nurturing the Heavenly Dao, accommodating the Heavenly Dao, or eventually accommodating the Grotto Heaven, stripping away external conditions, it’s all a process of breaking through in Divine Thought and a Transformation of the spirit.

And when Supreme True Immortals face Heavenly Immortals or Immortal Masters face Profound Immortals head-on, the advantage of the Heavenly Immortals and Profound Immortals lies mostly in their superior Divine Thought.

The most ancient cultivation system merely includes the simple stages of Refining Essence into Energy, Qi Refining and God Transformation, Refining God and Returning Void, and Refining Void and Unity. Though with the passage of time, the crude division of these realms can no longer keep up with the era, some of the fundamental truths they contain still give food for thought. Before becoming immortal, cultivators cannot escape the constraints of the body, whether they undergo Divinity Transformation or Return to Void, they haven’t truly completed the cultivation stage of refining essence into energy.

Ye Yan spoke somewhat wistfully, "Until we become True Immortals, no longer consuming grains, free from concerns of birth, aging, sickness, and death, sustained by wind and dew, enjoying Eternal Life in leisure, as long as one’s spirit and Divine Thought are strong enough to continue, one can truly achieve eternal life without death."
