Li Chengfeng inhaled a mouthful of cold air, his eyes flashing with determination.
He stepped into what was known as the "Ghost Qi Spring Eye." This place, rather than being a spring eye,
was more like a deep and vast underground canyon, with a horizontal diameter of tens of miles, as if it were a masterpiece of nature's craftsmanship.
His divine sense spread out like a tide, thoroughly exploring the surrounding cave walls.
These cave walls, constantly eroded by the Earthly Fiend Qi, had become as hard as top-grade spiritual artifacts, making one marvel at the magical power of nature.
Li Chengfeng activated the "Flourishing and Decaying Sky-Reaching Art" and began to absorb the ghost qi here.
Instantly, he felt a cold and powerful force surge into his body, as if countless little ghosts were jumping and cheering in his meridians.
He couldn't help but praise in his heart, this was indeed a good place, cultivating here would simply yield twice the result with half the effort.
His mind raced, and he immediately had a plan.
He remembered that the Myriad Demon King had mentioned that the real "Ghost Qi Spring Eye" was located a hundred miles away, where there was a seal, and beneath the seal lay hidden secrets.
He had to figure out all of this, lest he miss the opportunity.
Li Chengfeng took a deep breath, his steps firm as he walked forward.
Within three miles, he immediately used a secret technique, transforming into a substitute puppet, sitting cross-legged behind a rock, and pretending to cultivate.
His true body, however, cleverly used the supernatural power of "Dust of Time" to conceal his aura, quietly sneaking towards the depths of the Ghost Qi Spring Eye.
The Myriad Demon King's divine sense swept past from a distance, and seeing Li Chengfeng honestly cultivating within three miles, he nodded and paid no more attention.
He wholeheartedly immersed himself in the insights Li Chengfeng had left him, which was his capital for survival in the future.
Sure enough, after only comprehending a small portion, he felt greatly benefited, and the path he had taken before suddenly became clear, as if he had gone from a narrow path to a wide and boundless avenue.
However, the Myriad Demon King did not know that while he was immersed in comprehension, Li Chengfeng had quietly entered the depths of the Ghost Qi Spring Eye.
The deeper he went, the denser the surrounding ghost qi became, as if he were in a ghost mist.
Every inch of his skin greedily absorbed the ghost qi, as if every pore was cheering.
When he had traveled within thirty miles, suddenly, a group of ghost creatures appeared ahead.
These ghost creatures were all low-level ghosts, equivalent to the cultivation of a Qi Refining stage cultivator, and were called "Ghost Soldiers."
Their faces were ferocious, and their eyes flashed with a faint green light, as if they wanted to devour Li Chengfeng.
However, Li Chengfeng was not afraid at all, his eyes flashed with a sharp light, and with a thought, the Soul Devouring Banner fell into his hands from the Hell Space.
Li Chengfeng walked forward in the dark cave, and a dozen ghost soldiers floated towards him, seemingly unaware of Li Chengfeng's existence.
They were just aimlessly absorbing the surrounding ghost qi, like willow catkins floating freely in the air in spring.
Li Chengfeng's eyes narrowed, and he suddenly waved the Soul Devouring Banner in his hand, and immediately a strong wind rose, and the Soul Devouring Banner turned into a size of a dozen feet, and a powerful suction force suddenly swept all the ghost soldiers into it.
The ghost soldiers let out wailing ghost cries, the sound was shrill, but in a moment there was no movement.
Li Chengfeng felt the increase in the power of the Soul Devouring Banner, and was extremely satisfied in his heart.
Each of the ghost soldiers here was a pure ghost soldier, they had absorbed the Earthly Fiend Qi here for many years, and were about to step into the realm of Ghost General, equivalent to the Foundation Establishment cultivator of humans.
Such a ghost soldier, for the Soul Devouring Banner, was simply the best tonic.
Li Chengfeng strode forward, holding the Soul Devouring Banner, while using the supernatural power of the Dust of Time to completely hide his aura.
He was like a ghost in the ghost mist, silently beheading every ghost he encountered.
Along the way, he killed hundreds of ghost soldiers, and the number of ghost generals in the Soul Devouring Banner also greatly increased, and its power doubled.
Suddenly, Li Chengfeng found several ghost generals leading dozens of ghost soldiers ahead, and they were entrenched in a peculiar place.
There were three acres of black grass, with black flowers blooming on top, and wisps of Earthly Fiend Qi were slowly emerging from them.
Li Chengfeng's heart moved, he had never seen such a strange plant, but he could also feel that this was definitely a good thing.
Just as he was thinking, the Seven-Colored Illusion Butterfly in the spirit beast bag suddenly buzzed, seemingly very concerned about these flowers and plants.
Li Chengfeng's heart moved, this Seven-Colored Illusion Butterfly was obtained from Myriad Demon Valley, and after his careful cultivation, it had become very powerful.
In addition to illusion, it also has the ability to tear and gnaw. Could it be that these black flowers have a great tonic effect on the Purple Illusion Butterfly?
Li Chengfeng had a plan in his mind, he knew that these small flowers might not be of much use to him, but for the Purple Illusion Butterfly, they were rare treasures.
He decided to leave these small flowers for the Purple Illusion Butterfly to enjoy, in order to enhance its strength.
Li Chengfeng shook the Soul Devouring Banner in his hand, and suddenly there were wailing ghosts in the ghost house, and the three great ghost generals led dozens of ghosts.
They rushed towards the two great ghost generals and dozens of ghost soldiers guarding the spiritual field in front.
A great battle ensued, the two great ghost generals were powerful, after all, they were native ghost generals, and Li Chengfeng's ghost generals were cultivated, although after his improvement, their power was not inferior, but it was still a situation of three against two.
Li Chengfeng assisted from the side, and suddenly gave a cold snort, this cold snort was like a bolt from the blue, and the two great ghost generals immediately felt a tightening of their souls.
Dizzy and dizzy, all the ghosts fell from the air with a crackling sound, and were instantly swallowed by Li Chengfeng's ghost generals and ghosts.
Then the Soul Devouring Banner rolled up and took them all into it.
How powerful were Li Chengfeng's methods, but he did not fully display them in the Wind and Cloud Sect.
This thunderous blow was indeed powerful, and it was simply one thing to subdue another for ghosts.
After doing all this, Li Chengfeng scanned with his divine sense and found that there were no traces of ghosts around.
He immediately patted the spirit beast bag, and dozens of Purple Illusion Butterflies flew out and pounced on the spiritual field.
They began to gnaw at those strange flowers and plants, and in a short while, two or three acres of flowers and plants were eaten clean.
Although the stomachs of the Purple Illusion Butterflies were small, their devouring ability was like a bottomless pit, and after eating, they still greedily spit out the Earthly Fiend Qi.
At this time, there were many patterns on the colorful wings of the Purple Illusion Butterflies, which were the traces of the ghost qi of the ghosts deeply imprinted on them.
Their heads became more evil, like Yakshas, and they were moving towards the first-order monster.
Slowly, they actually wrapped themselves completely with their wings, and their whole body was covered with a layer of black chrysalis.
Li Chengfeng was overjoyed in an instant, his Purple Illusion Butterflies were about to advance.
He was very happy in his heart, and immediately moved his mind and took them into the Hell Space, letting them get close to the blood pool and slowly hatch.
He looked forward to the strength of their hatching, which was undoubtedly a huge opportunity he had obtained in this adventure.
Li Chengfeng strengthened his determination to explore, and he accelerated his speed, because the distance of a hundred miles was not close, and a long delay might arouse the suspicion of the Demon King.
He sped all the way, and if he encountered good treasures, he would not hesitate to put them in his bag, and he would simply skip those that he was not interested in.
He killed dozens of ghost generals, so that the power of the Soul Devouring Banner continued to increase, and finally reached the level of a magic weapon, and the patterns on it became more strange and profound.
