Reverend Insanity: Dream Gu

Deep within Lin Yan’s body, a rich and violent power burst forth from within him, surging through every inch of flesh, bone, blood, and aperture. His body trembled slightly as the force washed through him again and again, as if he were being broken apart and remade from the inside out.

Bang! Bang! Bang!

Suddenly, a series of explosive sounds rang out throughout Lin Yan’s body. A vast scorching current swept through him, instantly shattering the effects of every Flame Path Gu worm that had modified his body—Fire Pattern Gu, Fire Aperture Gu, Flame Bone Gu, and the rest. Then the shattered powers fused together as one, imprinting complete Dao marks onto his physique.

If a Gu Immortal were observing him with investigative methods, they would see Lin Yan’s entire body covered in shimmering red lines intertwined with dazzling purple patterns.

These were complete Flame Path Dao marks... and Thunder Path Dao marks.

”Dao marks... entering my body?... is this the sign of one of the Ten Extreme Physiques?!” Lin Yan was deeply shocked. He could feel something within him rapidly taking root and growing.

In truth, every Gu Master possessed Dao marks. Using certain body-modifying Gu worms would leave behind Dao marks of the corresponding path, but most of them were fragmented and incomplete.

The battle strength of an Extreme Physique far surpassed those of the same level precisely because the Dao marks within their bodies were complete, often reaching dozens in number.

This was not all. As the vast fire qi within Blazing Yellow Heaven Pit poured into Lin Yan’s body, his aura continued to rise without end. His flesh and blood became crystal-clear like colored glaze, with a faint glow flowing beneath his skin.

Even without any method to inspect Dao marks directly, Lin Yan immediately sensed something was wrong. The number of Dao marks forming within his body was far beyond normal.

At the same time, he felt himself becoming the center of this place, as though his body had formed a powerful resonance with the entire Blazing Yellow Heaven Pit.

”Wait... Blazing Yellow Heaven Pit contains an enormous amount of Flame Path Dao marks. Could it be that because I continuously refined Flame Path Immortal Gu here, combined with the transformation of a Ten Extreme Physique, this change was triggered?”

He frowned deeply. Fortunately, the terrifying growth did not continue forever. After a few breaths, it gradually came to a stop.

If one could observe the changes inside his body, they would discover three hundred Flame Path Dao marks and fifty Thunder Path Dao marks had formed within him.

At that moment, Lin Yan felt unprecedented power flowing through every part of his body. Even the slightest activation of a Flame Path Gu worm caused its power to rise by at least tenfold.

Only now did Lin Yan truly understand the terror of Dao marks. For Gu Immortals, cultivation ultimately came down to two things—blessed lands and Dao marks. The more Dao marks one possessed, the richer the blessed land and the stronger their battle strength became. Under normal circumstances, the most common way to increase Dao marks was by passing Heavenly Tribulations and Earthly Calamities.

One hundred Dao marks could increase the power of a Gu Immortal killer move of the corresponding path by ten percent. And one thousand Dao marks could double its power. For Mortal Gu, the amplification was even more terrifying, often exceeding a hundredfold.

It was precisely because of this that Gu Immortals stood so far above Gu Masters.

Sun Cu was a clear example: upon becoming a Gu Immortal, he would have to overcome Heavenly Tribulations and Earthly Calamities. A single heavenly tribulation usually granted around seven hundred and fifty Dao marks, while one earthly calamity added another two hundred and fifty. Together, that was roughly one thousand Dao marks, already considered fairly average among Gu Immortals.

And now, the Dao marks within Lin Yan’s body were already approaching that level.

Limitless Demon Venerable supposedly possessed Dao marks comparable to a Gu Immortal even while he was still a Gu Master.. Just how in the world had he managed to achieve something like that?

Lin Yan sighed inwardly. Every Venerable was a freak who defied the common sense of cultivation. If they had not accomplished extraordinary things, they would not be worthy of being called a Venerable.

Thinking of this, Lin Yan felt he was not doing too badly himself. From deducing an Immortal Gu recipe, to refining an Immortal Gu, to stepping into a Ten Extreme Physique before Immortal Ascension—he had walked this path through Dream Path and repeated effort alone.

He had not relied on any great opportunity from the original novel. Those chances were either beyond his reach or had never belonged to him in the first place.

As soon as the commotion around Lin Yan ended, Rank 6 Immortal Gu hovering in midair seemed drawn toward his physique. Its red wings fluttered as it circled once in the air before flying straight toward him on its own.

At that moment, Sun Cu entered after sensing the disturbance outside. The instant he saw the scene before him, his expression changed drastically.

”You... really refined an Immortal Gu?”

Lin Yan held the Three Flavors Otherworldly Flame Immortal Gu in his palm. At the same time, he quietly kept his will within Dream Derivation Gu, remaining alert in case Sun Cu made a move.

Author Note --- Explanation How Mc Ten Extreme Physiques Achieve.

__ it’s just Theory not sure about true.

Creation Relic Gu raising a Gu Master’s aptitude to one hundred percent and causing the manifestation of a Ten Extreme Physique could be explained through the relationship between aptitude, human foundation, and the origin of humanity itself. The key point was that Creation Relic Gu did not possess two separate abilities, one to increase aptitude and another to create a Ten Extreme Physique. From beginning to end, it performed only one Human Path effect: developing the unrealized potential within the user’s human foundation and transforming that potential into cultivation talent. Below the limit of a normal Gu Master constitution, this appeared as a quantitative increase in aptitude. Once that limit was reached, continuing the same process caused a qualitative transformation.

The foundation of this theory lay in the creation of humanity. Ren Zu took his own life and gathered the corpses of his ten children, using their complete existences to feed rank nine Derivation Gu and create the human race. Therefore, later humans were not merely descendants carrying diluted bloodlines from Ren Zu and his children. Humanity itself had been derived from them. The ten complete human foundations represented by Ren Zu’s children participated in that derivation, which explained why the Ten Extreme Physiques could continue appearing among later humans.

Derivation Gu did not simply reproduce Ren Zu and his ten children. Their complete existences were transformed into countless different human possibilities, expressed in different combinations and degrees among later humans. Most Gu Masters possessed mixed and incomplete foundations, with none of the ten extreme possibilities developed sufficiently to determine their entire constitution. In rare cases, however, one extreme foundation gradually became dominant as the person grew or cultivated. Their constitution changed, their aptitude increased, and eventually the corresponding Ten Extreme Physique manifested. Thus, under natural circumstances, the development of the extreme human foundation was the cause, while one hundred percent aptitude was one of its outward manifestations.

Several examples from the Gu World supported the connection between aptitude, constitution, and the deeper human foundation. Bai Ning Bing’s Northern Dark Ice Soul Physique developed together with his rising aptitude, while Yin Yang Rotation Gu reduced his aptitude and suppressed the immediate danger caused by the physique. Blood Skull Gu could raise a Gu Master’s aptitude through the power of blood relatives, proving that aptitude could be changed by manipulating deeper aspects of a human being. However, it could only push aptitude toward ninety-nine percent while the user remained a normal Gu Master. The difference between ninety-nine and one hundred percent was therefore not merely numerical. Ninety-nine percent was the limit of normal aptitude, while one hundred percent belonged to the Ten Extreme Physiques and required a qualitative transformation of the Gu Master’s constitution.

First Gen Gu Yue’s plan further proved that the manifestation of an extreme physique could be deliberately influenced. Through Blood Path methods and generations of descendants, he attempted to create the conditions necessary for the Ancient Desolate Moon Physique to appear. His method was indirect, requiring an entire lineage to accumulate and develop the desired foundation over generations, but it demonstrated that the appearance of a Ten Extreme Physique was not completely beyond human interference.

The life-and-death immortal aperture revival method provided an even stronger example. By using the immortal zombie body of a Great Strength True Martial Physique cultivator as refinement material, Fang Yuan could revive while obtaining that physique himself. He even considered obtaining a Desolate Ancient Moon Physique immortal zombie for his second aperture, potentially allowing him to possess two extreme physiques simultaneously. This demonstrated that a sufficiently profound cultivation method could manipulate, transfer, and reconstruct the foundation of a Ten Extreme Physique within another cultivator.

These examples established several different routes toward manipulating aptitude and the Ten Extreme Physiques. Blood Skull Gu improved aptitude through bloodline. First Gen Gu Yue manipulated inheritance across generations until the desired extreme foundation could appear. The life-and-death aperture method transplanted an already completed extreme physique into another cultivator. Spectral Soul went further still, using all ten extreme physiques as part of the foundation for Sovereign Immortal Fetus Gu, an existence surpassing the limitations of any individual physique.

Creation Relic Gu belonged within this same system, but approached the problem directly through Human Path. It did not require generations of descendants or the body of an existing Ten Extreme Physique. Its effect acted upon the Gu Master’s human foundation itself. Aptitude was not merely a numerical property of the aperture, but an outward manifestation of the deeper foundation supporting the Gu Master’s cultivation. This was why manipulating bloodline, transforming the body, or integrating the foundation of an extreme physique could all influence aptitude and constitution.

Human qi further supported this relationship. During immortal ascension, the accumulated foundation of a Gu Master manifested as human qi. The Gu Master’s body, soul, experiences, knowledge, attainment levels, and other accumulations all contributed to it. This showed that Human Path could treat the different aspects of a person as parts of a complete human foundation. Creation Relic Gu followed the same principle by developing the unrealized potential contained within that foundation, with increased aptitude appearing as the result.

At lower aptitude levels, the process remained quantitative. Creation Relic Gu developed the Gu Master’s human foundation, completed deficiencies limiting cultivation talent, and caused aptitude to increase. Different Gu Masters possessed different foundations and amounts of unrealized potential, so the increase did not need to be fixed. As long as the improved foundation remained within the limits of a normal Gu Master constitution, the result was simply higher aptitude.

The true change occurred near ninety-nine percent. At this point, almost every deficiency that could be completed without changing the Gu Master’s fundamental constitution had already disappeared. There was no normal one hundred percent aptitude constitution beyond this boundary. To increase aptitude further, the human foundation itself had to undergo qualitative transformation.

Creation Relic Gu crossed this boundary through Human Path. Humanity had been derived from Ren Zu and his ten children, so the ten extreme human foundations were not completely foreign to later humans. Their possibilities continued to exist in different degrees and combinations among the countless results produced by Derivation Gu. Among the characteristics, inherited qualities, and unrealized possibilities contained within a Gu Master’s foundation, one extreme possibility naturally possessed a greater basis for manifestation than the others.

Creation Relic Gu did not create this possibility from nothing or randomly grant an external physique. It continued performing the same function it had always performed: developing unrealized human potential and completing the deficiencies limiting cultivation aptitude. The difference was that, near the normal limit, further improvement required the Gu itself to reach deeper into the user’s human foundation and develop the extreme possibility with the greatest basis for manifestation.

This process could be called Human Foundation Completion. At lower aptitude levels, Creation Relic Gu completed deficiencies without changing the Gu Master’s fundamental constitution. At the ninety-nine percent boundary, the remaining deficiency belonged to the constitution itself. The extreme human possibility began developing toward completion, causing the Gu Master’s bloodline, body, aperture, and constitution to change together as consequences of the same Human Path transformation.

The process followed the same fundamental direction as the natural manifestation of a Ten Extreme Physique, but Creation Relic Gu artificially accelerated and completed it. In a naturally developing extreme physique, one extreme human foundation gradually became prominent, the constitution transformed, aptitude increased, and the physique eventually manifested. Creation Relic Gu compressed this process by continuously developing the human foundation until further improvement required qualitative transformation.

Once the extreme human foundation became sufficiently complete, it determined the Gu Master’s constitution. The body and aperture transformed together, the Gu Master became capable of supporting perfect aptitude, and aptitude naturally reached one hundred percent. Thus, one hundred percent aptitude did not create the Ten Extreme Physique. The completion of the extreme human foundation produced both the transformed constitution and perfect aptitude.

This was why Creation Relic Gu could accomplish something Blood Skull Gu could not. Blood Skull Gu manipulated bloodline, which was only one aspect of the complete human foundation. First Gen Gu Yue manipulated inheritance across generations. The life-and-death aperture method transferred an already completed extreme physique. Creation Relic Gu, as a Human Path Gu, directly developed the incomplete human possibility within the Gu Master until it became complete.

Spectral Soul’s refinement of Sovereign Immortal Fetus Gu did not contradict this principle. His objective was not to create one Ten Extreme Physique, but to use all ten as part of the foundation for an existence surpassing their individual limitations. Creation Relic Gu operated on a far smaller scale, developing only one extreme human possibility within one Gu Master.

The complete principle was therefore simple. Aptitude was one manifestation of the Gu Master’s deeper human foundation. Creation Relic Gu increased aptitude by developing that foundation. Below ninety-nine percent, this development remained quantitative. At the normal limit, there was no higher aptitude the existing constitution could support, so further development required qualitative transformation. Creation Relic Gu completed the extreme human possibility with the greatest basis within the user, causing the human foundation, constitution, and aperture to transform together. Once that transformation was complete, aptitude naturally reached one hundred percent and the corresponding Ten Extreme Physique manifested.

Derivation Gu had taken the complete existences of Ren Zu and his ten children and transformed them into countless human possibilities. Creation Relic Gu followed the opposite direction on a far smaller scale: it took one incomplete possibility within a Gu Master and developed it toward completion.

The final one percent was therefore not simply another increase in aptitude. It was the point where further improvement required the Gu Master himself to become capable of possessing perfect aptitude.

And when that human foundation was completed, a Ten Extreme Physique was born.
