Shennong Sequence

In the secluded cultivation area of ​​the Imperial Immortal City, the stone door of the No. 5 secret chamber slowly closed, and the heavy array patterns lit up like flowing water, completely isolating the outside world from noise and spiritual energy fluctuations.

Inside the secret chamber, layers upon layers of spirit-gathering runes were engraved on the dark stone walls. The spiritual energy floating in the air was more than ten times denser than outside, and strands of it wrapped around Zhao Yun and Xin Ruyin like silver threads.

The two of them moved here to prepare for Zhao Yun's breakthrough to the second stage of the Great Dao Foundation Establishment, 'Dragon and Tiger Intertwining'.

Time slipped away like sand through fingers. The night was dispelled by the rising sun in the morning light. When the first ray of golden light pierced through the ventilation hole of the secret room and landed on the intertwined fingertips of the two people, the atmosphere in the secret room suddenly changed.

"let's start!"

Zhao Yun and Xin Ruyin lay facing each other, their auras intertwining, and the secret technique of yin and yang harmony quietly circulated between them.

In an instant, the sparks of Yin and Yang that flew out from the collision of their auras, under their deliberate guidance, drifted precisely into the world bronze furnace that Zhao Yun had manifested.

The world bronze furnace, condensed from the physical barrier of Zhao Yun's body, was covered with fine world patterns. Inside, it was filled with a furnace of yin-yang charcoal, which also contained special yin-yang spirituality absorbed by the spirit-severing insect. It was black with white and white with black, exuding a fierce and gentle power that could tear apart heaven and earth.

"Buzz!"

The moment the sparks fell onto the yin-yang charcoal in the furnace, a deafening roar resounded.

The first piece of yin-yang charcoal to come into contact with the sparks instantly lit up its black patterns, followed by a burst of bright white flames that licked the furnace wall like a viper's tongue.

In an instant, the flames spread like wildfire, and the entire bronze furnace was engulfed in flames. Black charcoal and white spiritual energy tumbled in the fire, and faint sounds of dragons and tigers mating could be heard.

Xin Ruyin frowned slightly, her fingertips forming a hand seal as magical power surged forth, wrapping around the flames like silk ribbons, preventing the fire from getting out of control and balancing the raging flames that had just started.

Zhao Yun then used his powers of two, maintaining the yin-yang harmony with Xin Ruyin on one hand, and immersing his mind in the twelve-zhang void of his inner world on the other. Countless material forces and Daoist rhymes flowed like stardust. Using the foundation-building chapter of the "All Spirits Return to One Heaven Immortal Scripture" as a guide, he mobilized the vast power of his inner world, continuously drawing out the 'power of creation' and injecting it into the World Copper Furnace.

The power of creation, like a milky white stream, merges with the flames in the furnace the moment it enters, intertwining with the fire energy of the burning yin-yang charcoal.

The originally raging flames gradually calmed down, and wisps of yin and yang energy were extracted from the fire, drawn by the power of creation, and slowly condensed at the heart of the furnace.

At first, there were only two thin strands of air, one black and one white. As time went by, the air strands became denser and denser, and eventually condensed into a spark the size of a pigeon egg. It was half black and half white, with the black side as deep as ink jade and the white side as clear as crystal. It was the prototype of the Yin-Yang Spark.

Subsequently, the Yin-Yang spirituality collected by the Spirit-Extinguishing Insect, which contained the purest Yin-Yang origins in the world, was precisely integrated into the Yin-Yang Fire Seed.

"Om-"

The Yin-Yang Fire Seed trembled violently, and a faint glow appeared on its originally lifeless surface, with flowing light swirling at the boundary between black and white. Although it had not truly developed sentience, it was no longer a lifeless inanimate object, but rather, like a sleeping young beast, it exuded a faint aura of activity.

Xin Ruyin sensed the change in the fire and smiled faintly: "It's done! This fire has been imbued with spirituality. As your cultivation deepens, it will continue to grow. In the future, it may even evolve into the 'Yin Yang True Fire' to burn away all the illusions of the world."

Of course, Yin-Yang Fire only manifests spirituality, but does not possess autonomous intelligence.

Otherwise, Zhao Yun would truly be in a predicament.

Therefore, within this Yin-Yang Fire Seed, there is only a faint wisp of living spiritual light flowing within it. Although it has more "life force" than ordinary dead fire, it always respects Zhao Yun's will. Whether it is restraint or release, hardness or softness, it can be done at will.

This is an extremely rare phenomenon in the cultivation world, known as 'the Dharma possesses a primordial spirit,' which ordinary cultivators would never encounter even once in their entire lives. Yet, it has now fallen upon this Yin-Yang Fire Seed, which even Zhao Yun himself found unexpected.

It was precisely because of this that he was able to pour out his divine soul power like a tidal wave without any hindrance, allowing it to seep into the fire seed in strands and begin to refine it deeply.

It should be noted that this Yin-Yang Fire Seed originated from the Yin-Yang Charcoal he had refined from various spiritual materials, and was further nurtured by the power of creation within his inner world. From the moment of its birth, the fire seed was imprinted with his aura and had an intricate connection with his soul.

Therefore, as soon as the power of the soul touched the fire seed, it flowed smoothly like a bird returning to its nest. In just half an incense stick's time, it imprinted an indelible mark of destiny on the core of the fire seed.

Once this mark was formed, Zhao Yun and the Yin-Yang Fire developed a deeper connection, allowing him to clearly perceive the pulse of every flame even with his eyes closed.

Moreover, just after the natal mark was stabilized, the Yin-Yang Fire Seed, which was originally only the size of a pigeon egg, suddenly burst out with an astonishing suction force. Inside the World Copper Furnace, the Yin-Yang Charcoal that had not yet burned out and was piled up to the height of a person melted at a speed visible to the naked eye!

Regardless of the residual heat, the yin-yang attributes, or even the wisps of spirituality hidden within the charcoal core, all of it was swept away by the fire like a whale swallowing its prey.

In the blink of an eye, the Yin-Yang charcoal inside the entire bronze furnace vanished without a trace. Only the ember swelled to the size of a fist, with black flames swirling like an ink dragon and white flames spreading like a silver phoenix. The two intertwined and burned fiercely in the furnace, emitting a contradictory aura that could both scorch the heavens and shatter the earth and nourish all things. Even the air in the sealed room was scorched and slightly distorted.

Xin Ruyin, who had been observing intently, noticed this and a glint of light flashed in her eyes. She immediately spoke up to remind him:
"Now is the time!"
First, moderate the temperature of the Yin-Yang Fire, then introduce it into my body to erode my foundation of water and fire. Once the foundation is loosened, use the Yin-Yang Charcoal I've accumulated as a base to ignite the Yin-Yang Fire, completely replacing this foundation of water and fire energy!

As Xin Ruyin spoke, Zhao Yun did the same.

He suddenly thrust forward, using the secret technique of combining Yin and Yang to first suppress the boiling Yin-Yang fire, which was as hot as molten gold, into a lukewarm stream of fire. He precisely controlled its temperature and then gently guided it into Xin Ruyin's body.

The fiery stream rushed straight at the source that Xin Ruyin had specifically controlled in her inner world. It was a manifestation of water and fire energy in her inner world, with dark water energy and crimson fire energy intertwined to form a cocoon. Zhao Yun's Yin-Yang Fire followed this phenomenon, refining and eliminating it little by little.

At this moment, Xin Ruyin was also enduring immense pain. Beads of sweat slid down her face, soaking her body, and her knuckles were white from clenching her fists tightly. Her entire body was tense, yet she didn't utter a single groan, silently enduring the pain... (End of Chapter)
