The full moon hung high in the sky, surrounded by stars.
Except for a few particularly dark spots, even ordinary people could see the road ahead clearly by moonlight.
Let alone a master of the Xiantian realm like Du Fei, whose senses were sharp and vision keen as lightning.
He could see as clearly in the dark as in broad daylight.
After walking for a while longer, Du Fei arrived at the familiar unfinished building once more.
Although he had moved out, Du Fei still came here to meditate and train at night. Firstly, he was accustomed to it and didn't want to change, and secondly, there was no quieter place nearby.
As for Pinggao Huafu, where he lived now, it was a bit far from the unfinished building. This was not a problem for Du Fei at all; even if he only used one-tenth of his strength to run, he could be faster than the world's sprint champions and sustain it for a long time.
Reaching the rooftop of the unfinished building, Du Fei first sat in meditation to regulate the true qi within his body.
Only then did he take out the Marrow Cleansing Pill he carried with him.
Du Fei's bottleneck in the Xiantian realm had actually appeared half a month ago, but Du Fei wanted to try it himself first, to see if he could break through.
After several failures, Du Fei finally faced reality: a bottleneck was a bottleneck. Even though Du Fei had cultivated like a rampaging storm for so long, reaching the Xiantian realm made further breakthroughs extremely difficult.
Therefore, Du Fei chose to take the Marrow Cleansing Pill on this full moon night.
He hoped to use the pill's immense power to help him break through the constraints of his bottleneck.
The true qi within his body had already reached its optimal state. Du Fei then slowly opened the porcelain bottle and took out the Marrow Cleansing Pill.
It was pure white like snow. As soon as it was taken out, a rich medicinal aroma filled his nostrils. Just smelling it made him feel refreshed, making it hard to imagine what changes it would bring after consumption.
With a hint of anticipation, Du Fei popped the Marrow Cleansing Pill into his mouth.
Unlike the Qi Gathering Pills before, which melted in the mouth, the Marrow Cleansing Pill Du Fei swallowed showed no signs of doing so.
A few seconds later, the Marrow Cleansing Pill entered Du Fei's stomach.
Strange, did this Marrow Cleansing Pill require a special method of consumption?
Just as a flicker of doubt crossed Du Fei's mind.
Boom!
In Du Fei's stomach, it was as if a concentrated bomb had detonated.
Immediately afterward, he felt as if his meridians and internal organs were about to split apart.
Following closely, a tremendous pain engulfed Du Fei.
Pain!
It was simply too painful!
For a moment, Du Fei's mind was completely blank, as the searing, bone-chilling pain rendered him incapable of doing anything.
How could it be so painful?
Du Fei had originally thought that taking the Marrow Cleansing Pill this time would be similar to taking the Qi Gathering Pill before; he just needed to circulate the true qi in his body to guide the medicinal power throughout his body.
Who knew that now, Du Fei was in so much pain that he couldn't even move a finger, let alone activate the true qi within him. That was simply a pipe dream.
At the same time, as Du Fei was in excruciating pain, on the verge of losing consciousness, the medicinal power formed by the Marrow Cleansing Pill's explosion was transforming into a pack of wild horses that had broken free, rampaging wildly throughout his body.
It was a random, aimless, and chaotic surge. However, these untamed steeds were not just running wild; wherever they passed, Du Fei's meridians or internal organs would be torn apart.
In a short while, Du Fei had already detected over a dozen internal injuries within his body.
No, if this continued, even if he endured the pain, his body would be too severely injured to recover.
Therefore, Du Fei desperately concentrated his mind, trying to activate the meager amount of stable true qi in his dantian.
The idea was good, but implementing it was as difficult as ascending to heaven.
First, the physical agony prevented Du Fei from calming down. Second, the violent medicinal power was constantly causing damage within his body.
Combined, if Du Fei had not already reached the Xiantian realm, even a slightly weaker martial artist would have long fainted from the pain or exploded to death.
No, this couldn't continue. If no change was made, even if he could hold on, the final outcome would be his internal organs being completely destroyed by the medicinal power, turning him into a cripple.
Du Fei bit his tongue hard, instantly regaining control of his body.
But he knew very well that this control would not last long, so he immediately urged the true qi in his dantian, which had not been agitated by the medicinal power, to begin circulating through the Heavenly Circuit.
However, when his true qi reached the meridians torn by the medicinal power, it would trigger another round of piercing pain.
Several times he almost lost control, causing the true qi he had painstakingly activated to collapse.
Fortunately, Du Fei persevered with great willpower.
After the first circulation, the second one was relatively easier.
However, after several Heavenly Circuits, Du Fei discovered that the medicinal power of the Marrow Cleansing Pill was still extremely violent, and he was unable to absorb it at all.
What should he do?
For a moment, Du Fei was plunged into a new dilemma.
However, the rampant medicinal power within his body constantly reminded Du Fei that time was running out, leaving him no room for slow contemplation.
Du Fei's original plan was to use the stable true qi in his dantian to slowly circulate the Great Heavenly Circuit, while simultaneously digesting and absorbing the violent medicinal power.
But now, time simply did not allow him to do so.
Since he could not digest it, he might as well use it to impact his bottleneck.
However, doing so required caution. If Du Fei were to use all the violent medicinal power in his body to assault his bottleneck simultaneously, he would likely be unable to withstand it himself before the bottleneck was broken.
Therefore, he carefully controlled his true qi, first manipulating one-tenth of the medicinal power to impact his bottleneck.
At first, there was no reaction.
But as Du Fei gradually controlled more medicinal power to assault the bottleneck, signs of loosening finally appeared.
Ten minutes later, with a soft pop from somewhere within Du Fei's body, like a balloon being punctured, Du Fei felt his ears pop.
The next second, Du Fei suddenly felt that the world before his eyes was different.
This difference was not that the world itself had changed, but rather that Du Fei's eyes and all his organs had undergone a cataclysmic transformation.
He felt as if the world before him had become a high-definition version, with every detail rendered perfectly clear.
Even though it was night, and the full moon overhead was obscured by dark clouds, it did not hinder his ability to see even more clearly.
He had actually broken through successfully. Du Fei couldn't help but clench his fists in excitement.
Moreover, after he successfully broke through the bottleneck, the originally violent medicinal power within his body also became obedient.
This time, without Du Fei exerting any effort to control them, they were obediently absorbed into his meridians by the circulating true qi.
