Controlling his breathing, Jiang Feng swiftly entered the state for cultivation. The flow of spiritual energy within him began accelerating under his guidance, as his cultivation rose, albeit at a snail's pace.
Feeling the strange core in his hands filled with berserk spiritual energy, Jiang Feng swallowed the last of his worries about it as he began taking in the spiritual energy from his surroundings.
Within a few seconds, a strand of dark blue began to be extracted from the bull's core. Following the first strand, more of the berserk spiritual energy came out as it flowed towards Jiang Feng, connecting onto him all over.
The spiritual energy filled with impurities immediately entered his dantian, leaving it the next second as it started circulating within Jiang Feng's veins.
Things were going very well, Jiang Feng's spiritual energy reserves and cultivation base immediately met with growth as they ascended at a pace faster than normal cultivation.
Just as Jiang Feng thought things would continue to go on so, a sudden pain gripped onto his heart as the flow of spiritual energy within was disrupted. Immediately afterwards, his spiritual energy began acting up as the impurities of the core's spiritual energy attacked his veins.
Tearing sensations spread from all over as Jiang Feng spat out a mouthful of blood.
He was quick to act as he exited cultivation, wanting to stop the impurities from destroying his body even further.
However, as if the core came alive, it continued sending spiritual energy to Jiang Feng, forcing him to re-enter cultivation.
Gritting his teeth, Jiang Feng held back the urge to scream in pain as he controlled his flow of spiritual energy, immediately using it to fight back against the impurities.
His spiritual energy reserves immediately began depleting at a rapid pace as a fraction of it was used to cleanse just a small part of the impurities. Yet, the impurities only continued to increase as they gathered up and formed clots in his veins, limiting Jiang Feng's flow of spiritual energy.
'Damn it! Why am I always facing with death?!' Jiang Feng complained inwardly.
Just then, Jiang Feng noticed the Ghost Fire laying dormant in his dantian.
Despite the impurities almost taking up his whole dantian, only the area around it remained unaffected.
Jiang Feng immediately understood that the Ghost Fire could cleanse the impurities on its own. Making use of this, Jiang Feng picked up his determination to survive as he pushed all of the impurities in his veins towards his dantian.
Thankfully, moving them was not as hard as cleansing them, costing only a little amount of spiritual energy to move a large part of them.
Half of his veins were immediately cleared up as the Ghsot Fire worked its wonders, incinerating the impurities and turning them into spiritual energy for Jiang Feng.
Yet, because of the huge amount, the Ghost Fire couldn't cleanse the impurities as fast as it came, causing them to start piling up in Jiang Feng's dantian, the most important place for a cultivator.
Taking things into his hands again, Jiang Feng started assisting the Ghost Fire in cleansing the impurities. Naturally, his efficiency paled against it, but every bit counts as the impurities slowly disappear from his veins.
Cleansing the final bits of impurities, the spiritual energy from the bull's core was fully absorbed.
However, Jiang Feng could only lament at his own loss, gaining not a single increase in strength nor spiritual energy reserves, but expending almost half of his spiritual energy, and that was left because of the spiritual energy gained in cleansing impurities.
'I never should have attempted to absorb that core.' Sighing inwardly, Jiang Feng's head dropped as he pondered about what to do.
All of a sudden, Jiang Feng's cultivation base began soaring.
Such a change was immediately noticed by Jiang Feng as he used Spiritual Sense to look at himself.
The next second, he was shocked to find his spiritual energy reserves expanding at a visible rate, even his spiritual energy recovered along it.
A dumbfounded expression immediately appeared on Jiang Feng's face as he continued to look at his cultivation base soar. From Foundation Building Middle Stage, rising at an increasing pace towards Foundation Building Late Stage. Heck, it just went past it!
Jiang Feng's feeling turned into excitement as he felt himself nearing the peak of his cultivation realm.
Power coursed through his body, pumping him with strength as the thin lines around his curves became even more apparent, showcasing the perfect figure he has.
Good things were destined to come to an end, though.
Noticing the mysterious energy that fueled his ascension for his cultivation base slowly diminishing, Jiang Feng crossed his legs in an instant, entering cultivation as he planned on making use of the rising force to push the limits.
Finally, the mysterious energy was used up.
Jiang Feng continued to persist as he siphoned the surrounding spiritual energy like a blackhole, forming an invisible vortex around him with his dantian as the center.
His cultivation base that had turned stagnant despite being only half a step away from Foundation Building Peak Stage moved again, heading towards the milepoint at a pitiful speed compared to before.
'Come on! Just a little more!!'
Steeling his will to reach Foundation Building Peak Stage at the moment, the vortex of spiritual energy around his expanded, sucking in more spiritual energy from the outsides of the cave.
'A single thread left!!'
Crack!
"Success!"
Getting off the ground, Jiang Feng celebrated in excitement as spiritual energy overflowed from his body. The vortex had also dissipated following his ascension, returning peace to the forest as a one-man-party went on within the cave.
Jiang Feng, was now a Foundation Building Peak Stage cultivator.
