I Fabricated the Techniques, but my disciple really mastered them?

Only if the Imperishable Qi of the Heavenly Grotto was consumed, would it continue to emerge to replenish and form a balance.

Furthermore, Imperishable Qi would not flow out of the Heavenly Grotto.

Glancing at Xu Yan, the eldest disciple was pondering over the Imperishable Qi, while Wu Tianan and others were curiously exploring the grotto.

"Once the Imperishable Qi enters the Divine Soul, it will dissipate consciousness, return to a state of unenlightened, unawakened mind..."

Li Xuan reminded aloud.

"Imperishable Qi?"

Xu Yan was startled, saying curiously, "Master, I feel that the Imperishable Qi seems somewhat special, as if it cannot be refined, but it is also extraordinary..."

The rest were alarmed, hastily containing their spirits for fear of absorbing the Imperishable Qi.

"The uses of Imperishable Qi are too numerous; although it cannot be refined like Spiritual Energy to enhance one's Cultivation Realm, it can still be used to cultivate Divine Skills, establish Prohibitions, and so on..."

Li Xuan briefly introduced.

The rest, he did not continue to explain, leaving it to his disciples to ponder.

"There are such benefits?"

Fang Hao was overjoyed and began to fumble with jars, preparing to collect Imperishable Qi.

"Can it be used for Alchemy?"

Su Lingxiu's eyes lit up.

"Yes, and no."

Li Xuan said indifferently, not closing off the possibility.

He suddenly thought of his own Alchemical Medical Martial Arts Divine Skill, the Divine Furnace of All Paths, which could melt all paths of Domain and wondered whether it could also melt Imperishable Qi?

Theoretically speaking, if it could melt even Paths, why not Imperishable Qi?

Imperishable Qi would only disperse when the Domain first opened or during the creation of Paths, and since the Divine Furnace of All Paths could refine all paths of Domain, in theory, it could also refine Imperishable Qi.

"It should be possible, but with my current strength, using the Divine Furnace of All Paths is insufficient to refine Imperishable Qi," Li Xuan concluded internally.

Xu Yan and others were collecting Imperishable Qi, preparing to cultivate Divine Skills.

Wu Tianan and other Spiritual Realm Martial Artists felt helpless with this; they could not utilize it and did not even know what Divine Skills were.

The concept of Divine Skills was unheard of in Spiritual Realm Martial Arts.

As Li Xuan walked through the Heavenly Grotto, suddenly, he kicked against something.

The grotto appeared to be a cave, but it was actually shaded with grey and black and bore no plant life, and the walls of the grotto were smooth, as though untouched by dust.

Curious about kicking something in such an environment, Li Xuan looked down.

It was a fist-sized, grey-black stone.

"This stone is somewhat special."

With a gesture from his hand, the stone fell into his palm.

Although it was only the size of a fist, it was as heavy as a great mountain.

Moreover, the stone had a similar quality to Imperishable Qi, giving a sense of imperishability and indestructibility.

"Imperishable stone?"

Li Xuan silently pocketed the stone.

He planned to test if he could refine it with the Divine Furnace of All Paths upon returning, to see if he could melt the stone.

"With my current realm, it's likely I cannot refine an Imperishable stone. Once I'm able to, it will also mean that I can refine Imperishable Qi."

Li Xuan mused to himself.

In the Heavenly Grotto, apart from this one Imperishable stone and Imperishable Qi, there was nothing particularly special.

As Xu Yan and the others continuously collected Imperishable Qi, the base of the grotto began to see more Qi flowing in.

"What's different about the site of the Heavenly Cave Ruins that the prodigies went to?" Wu Tianan asked Xin Mengrou curiously.

"That Heavenly Cave Ruin is very ancient; it's a mystery from which era it remains. It's much larger than this place.

"There are Divine Artifacts in the Spiritual Realm, and apart from several places in Azure Sea, only the Heavenly Cave Ruins of the Eighteen States have such artifacts.

"Moreover, the Divine Artifacts within the ruins are quite special; the materials needed to forge Divine Artifacts are all excavated from the ruins.

"However, after countless explorations, the Heavenly Cave Ruins today probably don't have much opportunity left."

Xin Mengrou explained.

The Heavenly Cave Ruins of the Spiritual Realm were the secret of the Transcendent Spirit Sect. Even though access was restricted each time, after numerous explorations, the ruins no longer held much opportunity.

While collecting Imperishable Qi, Xu Yan spoke up, "It would be good to see how that site differs from this grotto."

Li Xuan was also curious about how the Spiritual Realm's Heavenly Cave Ruins differed from this one.

This grotto had hosted the powerful entity known as the Seductive Witch.

Had a similar entity appeared in the other ruins but was suppressed?

Turning it into a ruin?

"This grotto still has the potential to be infiltrated, it must be sealed," Li Xuan thought.

If his guess was correct, and the Seductive Witch was an enemy from beyond this world, infiltrating through the grotto, then, even though the witch was dead, there could be other entities from beyond this world that could penetrate into the Spiritual Realm.

Given the relatively weak strength of the Spiritual Realm, it definitely could not handle enemies like the Seductive Witch.

Thus, as Li Xuan walked along the base of the grotto, he began drawing upon Imperishable Qi to form Prohibition glyphs, sealing the base of the grotto.

Xu Yan and the others, having collected enough Imperishable Qi, ceased their efforts.

"What is Master doing?" Meng Chong asked curiously.

"Sealing the Heavenly Grotto!" Fang Hao said, eyes unwavering.

The Master was using Imperishable Qi, tracing it into Prohibition glyphs to seal the base of the grotto!

"So, Imperishable Qi can also be employed in this way."
