Reincarnated as a Mosquito, I Sucked the Reborn Empress to Tears

”A Grotto-Heaven World that just died?”

Chu Sheng was stunned. This was the first time he had ever heard such a thing.

He asked hesitantly, ”Huh? Are you saying... after a Grotto-Heaven World dies... it becomes a Secret Realm?”

”You could say that.”

Immortal Venerable Shi Xi nodded and, like a teacher, began to enlighten this ”ignorant” junior on some common knowledge.

”A Grotto-Heaven World is a small world in the truest sense. It possesses a complete World Origin, the fundamental Laws that support its operation, and spiritual veins with self-sustaining Spiritual Qi.”

”These small worlds were typically created during the Ancient Times, or even earlier during the Primordial Era, by supreme experts who had stepped onto the path of immortality.”

A hint of longing for that glorious era crept into Immortal Venerable Shi Xi’s tone.

”However, the World Origin of a Grotto-Heaven World needs to be maintained by the power of an immortal expert. Otherwise, like a living being, it will slowly age and eventually die.”

”After the end of the Ancient Times, the Human Race could no longer achieve immortality. The vast majority of Immortals traveled far into the void, heading to the Spirit Realm.”

”The Grotto-Heaven Worlds they left behind on Blue Star began a long process of decay, having lost their maintenance.”

”When a Grotto-Heaven World’s Origin completely dies, its internal fundamental Laws will collapse. The spiritual veins will crumble, and the Spiritual Qi can no longer sustain its cycle, only continuously dissipate outward.”

”Eventually, it becomes a pile of spatial ruins—what you call a ’Secret Realm.’ The residual Spiritual Qi within will slowly dissipate over time until the place becomes a true dead zone, where not even mortals can survive.”

Chu Sheng listened, dumbfounded. He was starting to understand.

He seized on a key point and pressed for more.

”So, is that why the entrances and exits to Grotto-Heaven Worlds are erratic, while the entrances to Secret Realms are fixed?”

”Because it’s dead, it can’t move anymore?”

”Mm, it’s not entirely accurate, but there’s no major issue with you understanding it that way.” Immortal Venerable Shi Xi nodded in approval.

”If I’m not mistaken, the current Human Race on Blue Star still uses roughly the same standards for grading Secret Realms as we did in our era.”

”They mainly classify them based on the concentration of residual Spiritual Qi inside.”

”A Divine-level Secret Realm means its internal Spiritual Qi concentration is still high enough to support the survival of a Divine Realm expert.”

”A Demigod-level Secret Realm can support a half-step Divine Realm expert... and so on down to Emperor Level, Emperor Level, King-level... It’s the same principle.”

”I think... that is how it works.” Chu Sheng nodded.

Now he finally, truly understood!

’So... all Secret Realms will slowly decrease in level?’

’As the Spiritual Qi inside slowly dissipates, the Secret Realm’s level will also get lower and lower. A Divine Level will become a Demigod Level, a Demigod Level will become an Emperor Level...’

’It’s just that it’s only been a little over six hundred years since the Spiritual Energy Awakening, which is too short a time for the changes to be obvious?’

Chu Sheng felt like he had grasped the truth.

’And that so-called Divine-level Secret Realm is actually a Grotto-Heaven World that died not long ago!’

’The residual Spiritual Qi inside is still very abundant, with a concentration high enough for a Divine Realm expert to survive.’

’So, after people discovered it, they judged it to be a Divine-level Secret Realm and mistakenly thought it held the opportunity to ascend to godhood?’

”You’re not slow.”

Immortal Venerable Shi Xi nodded again, confirming his guess, but then shook their head.

”In reality, it’s impossible to ascend to godhood within a Secret Realm.”

”Even if the Spiritual Qi concentration is sufficient, the fundamental Laws there have already collapsed and the World Origin is dead. It simply doesn’t have the conditions to support a living being’s breakthrough into the Divine Realm.”

”The possibility of ascending to godhood only exists within a living Secret Realm—that is, a Grotto-Heaven World.”

Chu Sheng’s heart skipped a beat.

’It’s true!’

He immediately thought of the Witch Ancestral Land!

’Isn’t that place a living, breathing Grotto-Heaven World?’

’It has a World Origin, extremely abundant Spiritual Qi, and its Laws are completely unaffected by Blue Star’s Forbidden God Law!’

’As long as one’s talent is sufficient, it should theoretically be possible to cultivate to the Divine Realm inside!’

’Of course, the price would be never being able to return to Blue Star.’

’Looking at it this way, the true opportunities to ascend to godhood have always been hidden within those unknown Grotto-Heaven Worlds!’

’Including those five so-called ”Divine Domains”—they’re actually five super-massive Grotto-Heaven Worlds!’

Chu Sheng was filled with emotion.

He finally understood why modern humans knew so little about these things.

Even Gu Yuexi, who had reached the Peak of Emperor Realm in his previous life, had a very limited understanding of Grotto-Heaven Worlds and had no idea one could ascend to godhood within them.

Otherwise, the Witch Ancestral Land would have been occupied by human experts long ago. How would a mere mosquito like him have gotten the chance to benefit?

It couldn’t be helped. Immortal Venerable Shi Xi had just said it.

The Divine Revelation Era was a million years ago.

The Fall of the Gods Era was ten thousand years ago.

In between, human civilization experienced an incredibly long gap, extremely similar to the history of Earth, going through feudal, industrial, and technological ages.

Only with the Spiritual Energy Awakening over six hundred years ago did they return to the path of Cultivation.

With such a severe cultural fracture, it was no wonder they didn’t know these things.

”In that case...”

Chu Sheng rubbed his chin and began to re-evaluate the worth of that Divine-level Secret Realm.

’The opportunities there don’t seem as great as I imagined. It must be far inferior to the Five Great Divine Domains... Is it even worth going?’

He began to have his doubts.

Besides, the conditions for opening the Secret Realm were extremely strict.

It was said that it required ten Emperor Realm experts working together to open a stable passage to the Secret Realm.

’I don’t even have a Master now. I’m just a plain old Demon Beast. Where am I going to find ten Emperor Realm experts willing to open the door for me?’

’Isn’t that just ridiculous?’

But...

...if he didn’t go, he would feel incredibly frustrated.

’It is, after all, a so-called Divine-level Secret Realm. There are bound to be some good things inside.’

’Most importantly, if I don’t go, and with Gu Yuexi now missing, is the Human Race really going to be foolish enough to wait for her to come back before opening it?’

’Don’t kid yourself! If you don’t go, someone else will!’

’At that point, would the Divine Son slot they worked so hard to protect for so long just be handed to someone else for free?’

He couldn’t swallow that!

After agonizing over it for a long time, Chu Sheng decided to ask for Immortal Venerable Shi Xi’s opinion.

”Senior, what do you think?”

After hearing the opening conditions, Immortal Venerable Shi Xi analyzed them in a calm tone.

”It requires ten Emperor Realm experts working together to open?”

”That only proves that the Grotto-Heaven World did not die very long ago.”

”Its corpse, the Secret Realm’s space, has only just collided with Blue Star’s primary world-space, and the resulting spatial fissure is not yet stable.”

”To safely enter such an unstable spatial fissure, one would normally need a Divine Realm expert to take action, or multiple Emperor Realm experts to join forces and forcibly stabilize the spatial passage.”

Chu Sheng had a sudden realization.

’So that’s how it is.’

He sighed, completely discouraged.

”Then there’s no way. I definitely can’t get in.”

However, Immortal Venerable Shi Xi’s tone suddenly shifted.

”Not necessarily.”

”With ordinary methods, you certainly cannot enter.”

”But I have another way for you to enter safely!”

”Even if you are only at the King-level right now, you can still get in!”
