Mortals cultivate immortality, and their IQ is playing with their heartbeats

#515 - Advanced to the late stage of Danjie

Immediately following, the Nine Yang Pearl descended before Li Chengfeng, carrying its scorching heat. With a thought, he began meticulously carving runes onto the pearl. As his speed increased, the pearl became increasingly radiant, and the fire within spontaneously ignited.

Suddenly, a buzzing sound arose again during the forging process. An unusual flame emerged within the pearl, and within the flame, a drop of blood slowly condensed, eventually dripping onto Li Chengfeng's fingertip.

His mind raced, and he instantly understood—this was actually Phoenix Blood, the essence of the Nine Heavens Fire Phoenix! It turned out that the power of the Nine Yang Pearl relied entirely on this drop of essence blood.

Li Chengfeng immediately used the Heaven and Earth Self-Sealing Technique to seal and preserve it for future use, then continued the refinement.

Ten days later, the Nine Yang Pearl and the sword embryo were finally completely fused, and all three were placed into the sword furnace together.

The three sword furnaces slowly rotated around Li Chengfeng as he unleashed a series of hand seals. At the same time, he summoned the other thirteen swords, each flying into its corresponding sword furnace. The sixteen swords revolved around him as he began a new round of refinement.

Each time his cultivation advanced, he gained new insights that needed to be incorporated into the sword, causing his sword to grow rapidly along with him.

As layers of restrictions were applied, the sword furnaces gradually sank into the raging flames.

The next task was entrusted to Old Demon Vermilion Bird and Li Chengfeng to work together. It was estimated that in another ten days, the divine sword would be ready.

Li Chengfeng seized that moment and successfully entered the middle and later stages of Core Formation.

The reason he was so eager at this time was because he planned to use the Soul Summoning Technique. The stronger his strength, the greater his chance of success, intending to give the other party a shocking surprise.

It should be known that each realm breakthrough meant a leap in strength, and the late stage of Core Formation was only one step away from the Nascent Soul stage, which was something he had dreamed of.

Li Chengfeng deeply understood the importance of being well-prepared. Although he had already made an appointment with the other party, 'Know yourself and know your enemy, and you will never be defeated.' The other party's true intentions were still unclear, and he had to formulate a comprehensive strategy.

While arranging for Old Demon and Little Vermilion Bird to refine the materials, he moved his mind and entered his own domain space, beginning to delve into the study of that drop of essence blood.

He first suppressed the essence blood above the blood pool with immense power, and then used the method of drawing firewood from under the cauldron, suddenly drawing out a weak wisp of soul.

Although this wisp of soul was weak, it revealed an aura of dominance and arrogance.

"This is the backup I left for myself. You dare to touch the essence blood of the Nine Heavens Fire Phoenix?"

The soul wisp was mixed with a threat, "This is an opportunity from a Body Integration Realm existence, my true self is Great Ascension Realm Ruan Ying."

But Li Chengfeng remained unmoved, only saying indifferently, "So that's how it is."

Immediately following, he used the Soul Collection Technique to completely shatter the remnant soul, but did not find the expected abnormal aura, indicating that the information contained in the essence blood seal was limited.

Li Chengfeng did not hesitate and immediately used the 'Heaven-Shaking Myriad Demon Transformation' to refine the essence blood.

The essence blood churned within his body, trying to suppress the raging fire within him, but when the Void Fire War Dragon encountered the Phoenix Blood, it was not suppressed but quickly refined.

A phoenix cry erupted from his body, and he instantly transformed into a dazzling Nine-Tailed Heavenly Phoenix, circling and dancing within the domain space, as if reborn from Nirvana.

The power of Nirvana surged in his heart, allowing him to comprehend the immortal mystery of the Phoenix's Nirvana—as long as the fire spirit remained, it could be reborn from the ashes.

This understanding was deeply rooted in Li Chengfeng's heart, merging with his Nirvana Sacred Art, gradually becoming one.

A new force was brewing within him, eventually transforming into countless divine runes, which quickly combined, causing a tremendous change in his temperament.

The power of dragon and phoenix intertwined and twisted within his body. Unfortunately, the Nine Heavens Fire Phoenix was also a fire spirit body, with the same origin and lineage as his Void Fire War Dragon.

If he could fuse the power of Yin and Yang, his strength would definitely reach a new level, and his understanding of the Great Dao of Yin and Yang would be even more profound.

Thinking of this, he smiled slightly, left the space, and then sat down cross-legged.

At this time, his entire body was filled with mana, only one step away from breaking through, waiting for the flying swords to be completed.

In the blink of an eye, a month had passed, and with a 'buzz,' the sound of swords echoed through the clouds.

Subsequently, three flying swords broke through the air and happily revolved around Li Chengfeng.

The first sword was named 'Nine Yin Sword,' which contained a bone-chilling coldness. With a gentle wave, it could freeze the surrounding space, and mortals who touched it would instantly turn into ice sculptures.

This sword was particularly sensitive to extremely cold and icy objects, as well as Yin and evil ghosts, and could slay demons and eliminate evil, connecting to the Netherworld.

Immediately following, there was another crisp sword cry, and the 'Nine Yang Sword' kept revolving around Li Chengfeng.

Because Li Chengfeng had refined the Phoenix Blood, this sword was exceptionally close to him, as hot as fire, like the essence of the sun, able to cut off all evil in the world, and absorb the power of the sun's true fire, merging with the power of the stars, making it even more domineering.

The most peculiar was the 'Earth Treasury Sword.' Two auras flowed on the sword body, both Buddhist and Demonic, the fusion of Buddha and Demon, flowing endlessly, like a pattern woven from Yin and Yang energies.

Rather than saying it was a sword, it was better to say it was a Yin-Yang diagram carefully woven by an Onmyoji. This sword rotated in the air like a full moon, representing the harmony and balance of Yin and Yang.

With a thought from Li Chengfeng, sixteen flying swords traveled like a stream of fish and entered his dantian.

He once again cast a spell, and in an instant, the surrounding scenery changed.

He had been suppressing his power for a long time. He could have broken through at Old Tortoise's place, but now he could finally no longer bear it.

In addition, with his dual cultivation with the red-clothed woman Dai Qianmo, both his divine soul realm and mana had reached their limits, and a powerful force surged out of his body.

Fortunately, he had set up a heaven and earth formation here, and the outside world could not detect the changes inside at all.

With the sudden explosion of strength, his journey ushered in a harvest, successfully advancing to the late stage of Core Formation.

The mana in his body was surging and澎湃, several times that of the middle stage, and the golden core had also expanded by a factor, with nine small golden cores slowly rotating around the large golden core.

His gaze was deep, he exhaled a breath of turbid air, carrying an old smell, his whole body's pores stretched, and the runes in the sky instantly dissipated and reorganized, condensing into Li Chengfeng's figure.

Now, he could freely use the convergence and dissipation of power, reborn from Nirvana, even better than before.

Just then, a heart demon suddenly invaded his sea of consciousness, it was the heart demon of the late Core Formation stage.

It chuckled and said, "Li Chengfeng, what you have done is against the way of heaven, too much killing, I will represent the way of heaven to punish you."

Before the words were finished, it was interrupted by a "poof" sound, and a monster-like existence strangled its throat.

"I am a heart demon, formless and immaterial, how can I be bound?" The heart demon struggled in disbelief.

However, the one who caught it was Li Chengfeng's heart demon incarnation, wearing black armor, with a strange power emanating from his left hand: "I have been waiting for you for a long time. Although you are a powerful heart demon in the late Core Formation stage, if I didn't have the Forbidden Armor to protect me, it would be difficult to defeat you. Now, you will become my nourishment."

After saying that, it directly dragged the heart demon to its mouth and sucked it into its body in one gulp. The heart demon churned in its belly, taking on thousands of forms, while Li Chengfeng's face was filled with gratification and excitement, and he laughed loudly.

After a while, the heart demon was finally suppressed, and Li Chengfeng's strength soared again.

However, this power was like a deflated ball, quickly merging into his body, allowing him to stabilize his late Core Formation stage realm.

He suddenly opened his eyes, with a smile that was not a smile, fully aware of all these changes.
