Shen Mo activated his cultivation method, attempting to extract and refine the spiritual energy of this place. He found that over 60% of the spiritual energy had become decayed and dormant, almost impossible to refine into his own Mana. It could only be regarded as Turbid Qi to be expelled from the body. The remaining 40%, while seemingly still thicker than in the Outer Realm, was almost devoid of Clear Spirit Qi. It was weaker than the Primordial Realm, and the overall effect was even worse than cultivating in places with thin spiritual energy in the Outer Realm!

Moreover, if other cultivators lacked Skills or cultivation methods with effects similar to "Flawless," refining this decayed and dormant Turbid Qi into their bodies would not only fail to increase their cultivation but would also adversely affect their Dao Body, Mana, and soul. This, in turn, would damage their cultivation level and Lifespan!

Of course, individuals like the Silver-haired Child, who had managed to cultivate to the Divine Bridge Realm, more or less possessed mysterious means to expel Turbid Qi and Evil Qi. Shen Mo didn't need to worry about them.

The scenery and nature's spiritual energy in the Immortal Mansion Dungeon all seemed as if they had experienced billions of years, becoming extremely withered and silent, which appeared somewhat abnormal. Even the Mountain River Realm and Jade Pool Realm, which had existed for an unknown period, were merely unable to maintain their Fairyland status; they had not declined as much as the Immortal Mansion Dungeon!

This situation implied one of two things: either the creator of this cave paradise had fallen billions of years ago, and it had existed as a Dungeon for far too long, or this Dungeon itself was inherently strange.

Since individuals like the Silver-haired Child and Immortal Master Cizi had determined that there were celestial treasures in this True Immortal's cave mansion and were willing to risk their lives to explore for them, the former possibility was infinitesimally small. After all, no matter how mysterious and extraordinary a celestial treasure might be, it could not withstand the erosion of billions of years!

Besides the abnormalities of this place, the terrifying suppressive power pervading this realm also makes me somewhat suspicious…

Immediately, he waved his hand, drew out the Soul Refining Flag, and summoned five Class II, five Class III, and five Class IV Demon Soul Generals from the blood flag.

After probing, he was surprised to find that the lower the Cultivation Realm, the weaker the suppression, and the higher the Cultivation Realm, the stronger the suppression. The power of the Class II Demon Soul Generals did not change much. The Class III Demon Soul Generals fell by one Minor Realm, and the Class IV Demon Soul Generals fell by a full two Minor Realms!

Three years ago, Shen Mo had entered the middle-stage of the Divine Bridge Realm, thanks to refining a True Immortal's Finger, and he was not far from the late-stage of the Divine Bridge Realm.

Now, under the suppression of an unknown mighty power, whether he used magic and martial arts or activated a Skill, he could only demonstrate the effect and power of the peak Golden Core Realm. Only his Special Destiny effects were unaffected. It was as if he had suddenly fallen back to the Golden Core Realm! 𝒻𝘳ℯℯ𝑤ℯ𝒷𝘯ℴ𝓋ℯ𝘭.𝑐ℴ𝑚

The Silver-haired Child, Kang Haoxiu, and Qin Zhen had their strengths similarly suppressed to the late-stage or peak Golden Core Realm.

Shen Mo, his expression unchanged, glanced at the Silver-haired Child.

This old fellow has hidden another key piece of information. No wonder he so confidently guaranteed that we have a great chance of successfully retrieving the remains on this journey… In the Immortal Mansion Dungeon, the suppression on a Formless Immortal Master would be even more severe; it would be remarkable if they could exert the strength of the initial Divine Bridge Realm. Thus, the gap between our group and Formless Immortal Masters like Immortal Master Cizi has invisibly narrowed. A perilous situation that could cause a Formless Immortal Master to fall would, for us, not be as dire or inescapable as we had initially predicted!

This Dungeon was originally a Fairyland created by that True Immortal! This place is so strange. Presumably, when that Immortal created this cave paradise, he didn't intend for it to be purely a cultivation sanctuary but planned to use it as a battlefield. Shen Mo waved the blood flag, recalling the summoned Demon Soul Generals, silently pondering.

Just imagine. When encountering a formidable opponent of the same level, the master of this cave paradise could lure them into his Fairyland. Upon entering the cave paradise, his enemies would suddenly discover their strength suppressed by several Minor Realms. Meanwhile, the master of the cave paradise, being its ruler, would be completely unaffected. How despairing his formidable enemies would feel! Of course, generally, cultivators wouldn't recklessly intrude into another's cave paradise unless they had absolute confidence in shattering it... Even if the cave paradise were a normal world, its master would be akin to The Heavens within it. The mere ability to teleport at will would grant a significant geographical advantage, not to mention other favorable factors. Outsiders would find it very difficult to gain any advantage!

Shen Mo did not want to argue with the Silver-haired Child, but Kang Haoxiu and Qin Zhen felt differently. They quickly cornered the Silver-haired Child, questioning him about why he had concealed such crucial information.

The Silver-haired Child smiled apologetically and managed to placate the two after much persuasion. After wiping the cold sweat from his forehead, he earnestly began searching for the traces left 6,500 years ago by his past self, Immortal Master Cizi, and their companions!

After a moment, he returned, excitedly shouting, "Although thousands of years have passed, the path my friends and I cleared by battling our way through obstacles is still here! If we follow this path deep into the Immortal Mansion, we shouldn't encounter too many dangers!"

"Fellow Daoist Qingyun, please recall your Spirit Pet. It's too conspicuous and could easily alert the demons and monsters in the cave mansion."

"When we venture deeper into the cave mansion, remember to follow closely behind me. Don't wander off..."

After entering the Immortal Mansion Dungeon, the Silver-haired Child seemed like a changed person. He began meticulously explaining all sorts of precautions and necessary information to the three of them, and Shen Mo and the others readily agreed to comply.

Then, the group members each employed their Escape Magic, following the Silver-haired Child's lead as they flew towards the depths of the Dungeon.

Due to the unknown oppressive force, their escape speed was not fast, maintaining roughly ten li per breath, comparable to the peak Golden Core Realm. After all, the suppression on the powerful in this place was all-encompassing; the speed of their escaping light was also significantly limited!

The scenery along the way remained just as dilapidated, but their overall situation had clearly become more perilous than it was near the entrance.

Even in such a dilapidated Dungeon, bizarre-looking Demons still resided!

Many Demons, judging by their physique, appearance, and aura, could barely be recognized as common types found in the Immortal Realm. However, because they had been isolated from the Outer Realm for too long and the environment here was peculiar, they had all undergone significant changes, resembling creatures never seen before.

Some Demons had never appeared in the Outer Realm, or in places like Jade Spring Mountain and Five Dragon Mountain. Shen Mo had to rely on "Insight into All Beings" to identify their species and origins.

Advancing along the path, these ferocious and bloodthirsty Demons were no less numerous than elsewhere. They could roam freely and would quickly occupy territories left vacant after powerful Demons were slain by the group of five, including Fulong Immortal Master and Immortal Master Cizi!

Fortunately, these Demons were also subject to the suppression of the mysterious force. Even a Class V great demon, much like Shen Mo and his companions, could only exert strength equivalent to the late-stage or peak Class IV.

Any who were foolish enough to act as obstacles met a grim end at the hands of Shen Mo's party.

Even Qin Zhen, the Nine-tailed Fox Demon, showed no mercy when killing these Demons. She was even more decisive and ruthless than Shen Mo, the Silver-haired Child, and Kang Haoxiu!
