The cultivators at the cave entrance also wanted to follow inside, after all, the Celestial Dragon Temple charges were exorbitant, and entering without paying could save them a large sum.

However, just following in like this might not be acceptable to the Celestial Dragon Temple. When it came to settling accounts, they wouldn't be able to handle it.

The group of cultivators watched eagerly as Gao Xuan and his companions disappeared but none dared to move recklessly.

After entering several dozen feet from the cave entrance, the passage began to slope downward. On both sides of the cave, an oil lamp was placed every few feet. This little light was like daylight for cultivators.

No one knows how many people have walked through this cave; the ground has been worn smooth. However, on both sides of the cave, dried bloodstains could still be seen.

Obviously, there have been bloody battles here.

As the passage continued downward, the cave grew colder and darker.

The three walked for about half an hour when the space suddenly opened up.

This was a grand cavern with hundreds of massive stalactites hanging from above. These stalactites emitted a greenish glow, illuminating the cavern in a ghastly green.

The cavern was so vast that its end was not visible upon a glance. The ground was filled with oddly shaped green glowing stones.

These dark green stones resembled demons, looking quite terrifying.

Celestial Fool had been here a few times and was familiar with this place. He explained, "This is the first layer. Under the condensation of Yin energy, these stones often transform into demons. However, the Yin energy here is too weak, so the demons transformed are very feeble.

"Cultivators entering the Cave of Ten Thousand Demons usually head to the third to fifth layers, where there are more demons, but it's still not too dangerous."

Most cultivators entering the Cave of Ten Thousand Demons do so to hunt demons for rare materials.

The more powerful the demon, the more precious and valuable its materials are. Hence, there's always a thrill-seeker among the cultivators willing to delve deep into the Cave of Ten Thousand Demons.

Those daring to venture into the Cave of Ten Thousand Demons adventure aren't likely to linger in the first layer.

Gao Xuan nodded without speaking. Having absorbed the memories of the monks, he was even more familiar with the Cave of Ten Thousand Demons than Celestial Fool.

However, Ripples knew nothing, so Celestial Fool's explanation was still useful to her.

As they had plenty of time, Celestial Fool led Gao Xuan and Ripples in exploring layer by layer downward.

The Cave of Ten Thousand Demons wasn't complicated; it was distinctly layered, with marked paths for entering and exiting.

Due to frequent passage by people, those paths had many signs of wear. Also, the Celestial Dragon Temple had placed some markers on these roads. Even inexperienced people wouldn't lose their way.

When the trio reached the third layer, they encountered several groups of cultivators. Most of these cultivators banded together in threes and fives, warily watching strangers.

The Cave of Ten Thousand Demons is chaotic, and even if one were killed, there's no place for justice. Cultivators entering here are very cautious and vigilant.

Gao Xuan did not engage with this group of ordinary cultivators; their levels were too low, and they were all preoccupied with making a living, being especially petty and profit-driven, leaving nothing much to discuss.

Upon reaching the fifth layer, there were many cultivators. One could often see a group of cultivators engaged in a fierce battle with an ugly demon, the visual and sound effects being quite spectacular.

The demons here were transformed from Ultimate Yin Filthy Qi, grotesque in appearance. Usually, they took on various beast forms. Their bodies were covered with bumps, exuding a strong foul odor, making them quite repulsive.

However, to the cultivators, slain demons were treasures. Gao Xuan and his companions saw a few cultivators happily and eagerly dissecting a demon corpse, dividing bones, organs, and tendons neatly, making it look similar to butchering a pig.

Below the tenth floor, cultivators were rarely seen. The Yin energy here was increasingly dense, and Ripples slightly frowned, feeling somewhat uncomfortable.

Ripples was very powerful in combat, but lacking a physical body and being a pure spirit body, her resistance to Ultimate Yin Filthy Qi was very weak.

Gao Xuan didn't offer any help; Ripples ultimately needed to acclimate herself to corruptive energy. The Cave of Ten Thousand Demons was naturally divided into many layers, making it very suitable for Ripples' cultivation.

By the time they reached the twentieth layer, Ripples' face was turning slightly blue. By relying on Sword Intent to transform, she could resist the Ultimate Yin Filthy Qi, but she was beginning to struggle.

Seeing Ripple's condition, Gao Xuan knew it was not suitable for her to go any deeper. Grinding had to be gradual.

He said, "Let's rest here for a while."

Ripples sighed in relief, immediately grabbed Gao Xuan's arm, taking deep breaths. Only by Gao Xuan's side could she absorb pure Spiritual Qi.

Gao Xuan found it a bit amusing. He searched within the Great Mighty Celestial Dragon Claw and found a small Profound Sun Mirror. 𝙛𝓻𝒆𝓮𝒘𝙚𝙗𝒏𝙤𝙫𝓮𝒍.𝓬𝒐𝙢

This mirror came with its own Profound Sun Power, specifically used to protect the Divine Soul and ward off Yin qi. This immortal artifact was also a treasure of the Profound Sun Dao.

Gao Xuan had destroyed the Profound Sun Dao, leaving all its treasures.

Though the Profound Sun Mirror wasn't suited for combat, it was perfect for Ripples. Gao Xuan hung the Profound Sun Mirror around Ripple's neck, where the crimson golden light shimmered slightly, naturally isolating the surrounding Ultimate Yin Filthy Qi.

Ripples found that wearing the mirror felt warm and comfortable, and curiously fiddled with it.

The inside of the mirror was filled with complex runes that she couldn't understand.

Gao Xuan said to Celestial Fool, "Your magical feats at the Profound Sun Daoist School are quite exquisite. What is the name of this technique?"

"The Celestial Capital Soundless Thunder Sword."

Celestial Fool proudly said, "In my six thousand years of life, this is the only magic technique I developed. It uses the Formless Sword as its body to carry the power of Tribulation Thunder, transforming into a Thunder Sword, embodying Supreme Yang and Fierce while remaining formless…"

This secret art is Celestial Fool's self-realized ultimate skill, and he hadn't even taught it to his direct disciples.

However, since Gao Xuan asked, he wouldn't hold back.

To be honest, Celestial Fool was waiting for this opportunity. He thought very clearly that with Gao Xuan's unparalleled divine techniques, he wouldn't care about the Celestial Capital Soundless Thunder Sword.

Celestial Fool detailed the entire technique, from the cultivation techniques to the principle changes, explaining everything clearly.

After all, he had delved into this for thousands of years. In terms of this technique, no one in the Cyan Celestial Realm could compare to him.

Converting Supreme Yang and Fierce Thunder to Ultimate Yin and Soft—such a transformation was indeed ingenious.

Gao Xuan nodded upon hearing it. At its core, it was about using the Formless Sword as the foundation, with the Yu Jing Dao Celestial Capital Thunder Technique as the root, enabling the transformation of Yin and Yang, creating endless variations.

Celestial Fool even shared the Yu Jing Dao's Supreme Secret Technique, the Celestial Capital Thunder Technique, explaining it all with divine sense transmissions, fully demonstrating its essence and spirit.

When he finished, Gao Xuan had already mastered the technique. It was just that without the Formless Sword, converting the Supreme Yang and Fierce Thunder to Ultimate Yin and Soft would be a bit difficult.

"Indeed an impressive secret technique."

After thinking for a while, Gao Xuan said, "The most remarkable aspect of this technique is the transformation of Yin and Yang. This is quite similar to the Jun Heaven Wheel that I've refined."

Gao Xuan suggested, "However, your Yin and Yang transformation isn't smooth enough, unable to directly convert external forces. It might be better to start from these points…"

Understanding the most fundamental laws of the Immortal Realm and having absorbed the memories of many powerful beings, along with obtaining numerous potent magical artifacts, Gao Xuan's accumulation far surpassed that of Celestial Fool.

Having trained in the revolving heavens, Gao Xuan's insight and wisdom were unmatched by Celestial Fool. Gao Xuan's current status was even comparable to that of an Earth Immortal.

With the aid of the Formless Nine Revolutions in simulating and deducing, Gao Xuan quickly found the key points of the Celestial Capital Soundless Thunder Sword and provided guidance to Celestial Fool.

Celestial Fool had deep accumulations, only lacking a bit in innate talent, making it challenging to take another step. In truth, he was just a paper-thin barrier away from a higher realm.

Once Gao Xuan pointed out this barrier, Celestial Fool felt enlightened, suddenly understanding previously confusing and obstructed areas. Though his power didn't increase, he ascended one level as a whole.

This improvement was reflected on the Divine Soul level, where he sensed vibrant boundless vitality.

Rejoicing in his enlightenment, Celestial Fool knelt immediately, proclaiming, "I will never forget the guidance of the Celestial Master!"
