The number of ghosts in the Soul Devouring Banner continued to increase, making it even more powerful. It already contained twelve ghost generals and a large amount of ghostly energy.
This ghostly energy was absorbed into the Soul Devouring Banner, allowing these ghosts to devour it and continuously strengthen their power.
The sudden appearance of a huge hole in front caught Li Chengfeng's attention.
Above the hole was a colorful seal, constantly twisting and emitting a powerful ghostly aura.
This seal seemed to be able to use the power of ghostly energy to enhance its own strength. It was truly a work of supernatural craftsmanship.
Li Chengfeng was attracted by this huge hole, and he stepped forward to carefully sense it.
The concentration of ghostly energy here was so strong that even a Golden Core stage cultivator would probably avoid it, but for Li Chengfeng, who cultivated the 'Flourishing Decay Sky-Reaching Art,' it was like a fish in water.
He slowly enveloped the rune with his divine sense and finally understood its operational trajectory.
This rune used the power of the other party to strengthen the seal. This method was definitely beyond what the Myriad Demon King could do.
After Li Chengfeng walked around the hole a few times, he placed his hand on the rune, injecting a trace of power to begin sensing.
Suddenly, his divine soul was pulled into the rune, which shocked him.
He wanted to pull his hand back, but a powerful force firmly fixed him on the rune.
After his soul was pulled into the rune, a special force twisted within his soul, trying to turn his soul into a part of the rune.
However, Li Chengfeng's soul was exceptionally powerful and pure to the extreme, and this force could not crush it.
On the contrary, he used this force to begin sensing the power of the rune.
Suddenly, his soul seemed to enter the myriad realms, and the vast universe was boundless.
Even a great cultivator in the late stage of the Nascent Soul realm would be instantly stunned by this kind of artistic conception, and even lose their soul and become possessed.
But Li Chengfeng's soul became even more resilient. He admired the beauty of this place and felt the process of the stars shifting and the world changing.
These vast star paths slowly flowed within the rune, eventually shrinking into this rune, branded here, sealing off the ghostly energy spring.
Li Chengfeng couldn't help but feel deep respect and curiosity for the person who created this rune.
Suddenly, with a 'bang,' his soul was ejected from the rune and returned to his body.
Li Chengfeng touched his chest with lingering fear, almost killing himself.
But he also understood that he had gained great rewards and enlightenment.
At this moment, a childish voice rang out on the rune, transmitted to Li Chengfeng's mind through divine sense transmission: "Bad guy, you are a bad guy, why don't you let me eat you?"
Li Chengfeng's mouth twitched, and he responded: "Who are you? Why do you want to eat me?"
The Rune Spirit replied: "I am the intelligence of this rune. I was just born.
I want to eat living people, not these ghosts. They have no thoughts.
When I eat the soul of a truly complete person, my wisdom will become more and more."
Li Chengfeng touched his chin and asked curiously: "When were you born?"
The Rune Spirit replied: "Just now. When you just approached, I suddenly gained intelligence and had the urge to devour your soul.
So I started according to instinct, but I didn't expect your soul to be so powerful that it almost broke my teeth."
Li Chengfeng smiled slightly and said: "It's okay if you want to eat a complete soul, but what are you going to exchange for it?
There is no such thing as unearned gain in the world. You can only exchange with me if you give me something of equal value."
The Rune Spirit asked excitedly: "Really? Can you really capture souls for me to devour?"
Li Chengfeng nodded and replied: "Of course. Li Chengfeng's words are as good as gold.
However, you must first tell me, what can you offer in exchange?"
The Rune Spirit thought for a long time and said helplessly: "This... I don't have anything now.
I just gained intelligence, and I haven't killed anyone, nor do I have any treasures. I'm just a seal, how could I have treasures?"
Li Chengfeng smiled and said: "How can you not have anything? Your rune is so exquisite that you can condense a miniature replica of the rune for me.
Remember, it must be complete. If it is complete, I will come back in two months and give you a living soul to enjoy."
The Rune Spirit said happily: "Really? That's great! I'll give it to you now."
The Rune Spirit was very particular and quickly condensed a miniature rune, which floated towards Li Chengfeng.
Li Chengfeng picked it up, sensed it in his hand, and then with a wave of his hand, the rune entered his body.
He began to slowly sense and fuse this rune, making his martial arts and spells more integrated.
Li Chengfeng was walking a special cultivation path. His body, blood, and other aspects were composed of tiny runes that could be gathered and scattered, with infinite power.
With the addition of this small rune, the runes in his body began to slowly hatch, and then turned into one, two, three... countless runes.
These runes merged with other runes in his body, and slowly his body would reach a perfect state.
Seeing that Li Chengfeng had successfully refined the rune, the Rune Spirit asked with a solemn expression and a hint of anticipation: "How is it? Is the rune I condensed okay?"
Li Chengfeng nodded and praised: "Not bad, it is indeed the complete version, very good.
You have given me a great opportunity, and I will definitely not treat you badly.
However, you must be careful. People's hearts are unpredictable. Don't believe other people's sweet words, or they will trick you out?
They will directly refine you like they refine the rune just now, and you will be miserable."
Hearing Li Chengfeng's words, the Rune Spirit shivered and hurriedly asked: "Really? What should I do then?"
Li Chengfeng smiled slightly, took out a jade slip from his storage bag, and handed it to the Rune Spirit, saying: "This is the experience of a wise man who wrote about the dangers of the human heart. Take it and read it. This way, you can increase your knowledge and avoid being deceived by others."
The Rune Spirit immediately used its divine sense to wrap the jade slip and extract the information inside.
After a while, his face became solemn, and he had obviously realized the complexity and danger of the human heart.
Seeing this, Li Chengfeng nodded with satisfaction and then said: "Now go and comprehend these experiences, don't disturb me, I want to condense Earthly Fiend here.
When you need pure ghostly energy, you can help me purify and transport it over."
"No problem, we are friends now, we are good buddies.
Your business is my business, don't worry," the Rune Spirit said carelessly.
He looked like he regarded Li Chengfeng as his good friend. After all, he had just gained intelligence, and the first person he saw was Li Chengfeng.
Li Chengfeng nodded and began to condense Earthly Fiend according to the Cultivation Art of the 'Flourishing Decay Sky-Reaching Art'.
With a flip of his hand, a jade box appeared in his hand, which was the Nine Nether Earthly Fiend that the Myriad Demon King had given him.
Opening the jade box, a strong evil aura suddenly surged out and was directly absorbed by Li Chengfeng.
The evil aura in his body became stronger and stronger, and the ghostly energy also poured in.
The Rune Spirit lived up to expectations, concentrating the emitted ghostly energy into a single point and injecting it into Li Chengfeng's body.
Under the blessing of this ghostly energy, Li Chengfeng's strength rapidly increased.
The Nine Nether Earthly Fiend was indeed powerful, worthy of being the King of Earthly Fiends, making the Nether Refining Astral Energy twice as effective with half the effort.
Li Chengfeng felt unprecedented progress and power in his cultivation.
