"The Cave of Ten Thousand Demons is situated deep within the Radiant Valley, at the heart of the Great Wind Country. At night, the valley is aglow with seven-colored lights, hence the name Radiant Valley. This light is merely the manifestation of the Ultimate Yin Filthy Qi leaking out..."

The Celestial Fool feared that Gao Xuan might not be familiar with the details, so he recounted the situation of the Cave of Ten Thousand Demons in detail from start to finish.

Originally, the Buddhist and Daoist sects took turns guarding the Cave of Ten Thousand Demons, but in the last few millennia, the Buddhist sect has dominated it.

Xuan Xiang even constructed an extremely grand Celestial Dragon Temple outside the Radiant Valley, which is also the most important temple in the Great Wind Country.

By custom, the Emperor of the Great Wind Country is required to visit the Celestial Dragon Temple every three years for a pilgrimage. Xuan Xiang naturally serves as the National Preceptor of the Great Wind Country.

The Great Wind Country is considered the strongest nation in the Northern Province, vast in territory with a large population. There are more than a dozen Loose Immortals within its borders, a testament to its strong national power.

In the last few hundred years, supported by Xuan Xiang, the Great Wind Country has continually expanded its territory and has become the hegemon of the Northern Province.

According to the tacit rules among cultivators, those above Spirit Immortal level cannot directly interfere in the struggles of various countries. However, Xuan Xiang broke this rule. His cultivation level was formidable, so no one could manage him.

On the other hand, such changes in national fate can severely harm cultivators. Many are waiting to see Xuan Xiang make a fool of himself.

Yet Xuan Xiang remained unscathed, which left many cultivators perplexed.

Gao Xuan speculated that Xuan Xiang relied on the Great Mighty Celestial Dragon to purify everything, thus he feared no backlash from the national fate on his divine soul.

This old man seemed accustomed to being domineering. Crashing into Gao Xuan resulted in a fatal encounter for him.

The Celestial Fool thoroughly explained the situation of the Cave of Ten Thousand Demons before getting to the point: "The Cave of Ten Thousand Demons is divided into dozens of levels. The upper levels are used by Buddhist disciples for cultivation, including cultivators from the Great Wind Country and other foreign cultivators. Anyone can enter to train as long as they pay money..."

"Once you get below the tenth level, the demons become extremely dangerous. Only Spirit Immortals can temporarily withstand the Ultimate Yin Filthy Qi to enter and slay demons. Therefore, at the tenth level, the Buddhist sect begins to set up seals."

The Celestial Fool glanced at Gao Xuan at this point, "The Buddhist seals were jointly set up by numerous Arhats and Golden Body Arhats. Once they die, their Divine Soul Marks dissipate, and the sealing power quickly fades."

Sikong Ling impatiently said, "Stop wasting time, just clarify the situation."

Sikong Ling and the Celestial Fool had a good relationship and spoke with little reservation. Besides, he was afraid Gao Xuan would get impatient, so he offered a helping word.

"In my estimation, if no one maintains the seals, all seals will automatically dissipate in less than a hundred days."

The Celestial Fool hesitated for a moment before saying, "The Buddhist Sect's sealing techniques are extremely wondrous. We are just a tier below. To reseal the Cave of Ten Thousand Demons, it would be prudent for the Celestial Master to personally intervene."

Having witnessed Gao Xuan's Inversion of Heaven and Earth Technique, the Celestial Fool believed that Gao Xuan must be well-versed in sealing techniques. With Gao Xuan's intervention, sealing the Cave of Ten Thousand Demons should not be difficult.

Gao Xuan considered it and said, "The Cave of Ten Thousand Demons is indeed a problem. I will first go see the situation and then decide how to handle it."

Although he was not familiar with sealing techniques, he had acquired quite a few such methods from the memories of many monks.

The most powerful sealing techniques included the Buddhist Six-Character True Words, the Unmoving Bright King Mantra, and others. The stronger the cultivator, the stronger the sealing power.

Gao Xuan did not need to specifically cultivate; simulating Buddhist spells with the Formless Nine Revolutions was not difficult.

Moreover, Gao Xuan felt it was unnecessary to go through so much trouble.

The Ultimate Yin Filthy Qi was very suitable for the Eternal Hell Seal. The Endless Hell Seal would absorb all of the Ultimate Yin Filthy Qi.

If the Eternal Hell Seal couldn't absorb it, he would use the World-Ending True Flame of the Great Mighty Celestial Dragon to purify it.

In the memories of Xuan Xiang and others, there was also detailed information about the Cave of Ten Thousand Demons. However, Xuan Xiang and Lingxu were not strong enough to truly resolve the root of the problem.

In fact, none of these Golden Body Arhats had ever entered the deepest level. They were also unaware of the true source of the Cave of Ten Thousand Demons.

Gao Xuan relied on his Innate Primordial Chaos Dao Body and did not fear the Ultimate Yin Filthy Qi. He intended to examine what the essence of the Cave of Ten Thousand Demons was like.

If he could address the root, the problem could be utterly resolved.

However, there was no need to discuss these plans in detail with the few Human Immortals. For them, maintaining the Cave of Ten Thousand Demons in a sealed state might be the best outcome.

Gao Xuan took on the most arduous task willingly, making the few Human Immortals pleased, and they couldn't help but utter a few flattering words.

Even Chen Royal Court, normally indifferent, displayed a slightly more enthusiastic attitude this time.

In truth, the few Human Immortals felt a bit awkward inside; after all, nobody liked an elder brother appearing out of thin air. Now that the elder brother was bold enough to shoulder the elder brother's responsibilities, acknowledging him did not seem like a loss.

The Celestial Fool volunteered, saying, "Disciple has been to the Great Wind Country and the Cave of Ten Thousand Demons. How about letting disciple lead the Celestial Master there?"

Gao Xuan was indifferent about it—having someone lead the way could spare some trouble. The Celestial Fool seemed rather amusing.

"If you are free, accompany me for a trip."

Gao Xuan said, "If the timing works out, perhaps you should arrange your affairs first. We will depart in ten days."

The Celestial Fool nodded, "That works. Timing should be fine."

The group finished their meeting and bid farewell to Gao Xuan together.

Gao Xuan walked them to the large hall's entrance, watching as Ripples escorted them out the main gate before turning to leave.

After leaving the Celestial Master Temple, the Celestial Fool waved to Ripples, "No need to see us off, return inside. We'll be on our way."

Ripples, not standing on ceremony, nodded to the Celestial Fool and the others before heading straight back inside the hall.

The four Human Immortals exchanged glances; what needed saying had long been said, and now there was no need for more words.

Chen Jiu Feng and Chen Royal Court left first, while Sima Ling accompanied the Celestial Fool back to the Yu Jing Daoist School in Daqiong Country.
