I forge immortality with a pagoda.

Shen Yu sat upright on a futon, with a Taoist book in front of him moving on its own without any wind, floating in the air.

Although his previous life-or-death battle with Wang Xuanxiu was fraught with danger, it also allowed him to thoroughly understand and master all the variations and techniques of this Taoist art.

At this moment, only the last and most crucial step remains to reach the ultimate mastery: completely unify the ninety-nine blazing flames within the dantian and condense them into a single "fire seed"!

This final step requires a pure and refined yang energy as a catalyst.

The Nine Dragon Mushroom in his hand was the key treasure for completing this final transformation.

Shen Yu calmed his mind and focused his spiritual sense into the Daoist book. He repeatedly comprehended the key points, obstacles, and potential risks of condensing the fire seed until he was sure there were no more obstacles. Only then did he slowly open his eyes.

He carefully took out the golden Nine Dragons Fungus and held it up with both hands.

After taking a deep breath, the Primordial True Qi within his body surged forth, transforming into a gentle ball of Qi that slowly enveloped the Nine Dragon Mushroom.

Refining, begin!

The Nine Dragons Mushroom seemed to possess a spirit, trembling slightly as it resisted the intrusion of external forces.

The nine dragon-shaped patterns on the sesame cap seemed to come alive, radiating a scorching heat.

Shen Yu remained calm and patient, guiding the flow of true qi with gentle, subtle movements.

Gradually, the hard surface of the Nine Dragon Mushroom began to soften, and strands of pure, incomparably yang essence, like flowing crimson gold, were slowly extracted and absorbed into Shen Yu's body.

As soon as this essence entered his body, Shen Yu felt a jolt throughout his body, as if he were in a furnace!

The boundless and powerful Yang energy surged and roared through his meridians like a river bursting its banks, causing waves of burning pain wherever it passed.

He dared not be careless in the slightest. Following the guidance of the Taoist book, he fully activated the method of the Fierce Nether Wind Summoning Technique, guiding this massive amount of essence into his dantian.

Within the dantian, the ninety-nine streams of blazing heat that had been circulating freely sensed this purer Yang energy and immediately converged like rivers flowing into the sea!

The essence of the Nine Dragon Mushroom forcibly squeezed the ninety-nine streams of flame. This process was extremely painful, and Shen Yu felt as if his dantian was about to be melted through.

Large beads of sweat rolled down his forehead, his skin turned red, and white steam rose from his body.

But he gritted his teeth and, with unwavering willpower, stubbornly maintained the operation of the incantation, guiding the process of fusion.

Time passed slowly, and the spiritual energy within the cave surged, causing the temperature to rise rapidly.

After an unknown amount of time, when the last wisp of the Nine Dragons Herb's essence was completely absorbed, a point of extreme light suddenly appeared at the center of the violent energy vortex within the dantian.

The light spot was initially as tiny as dust, yet it radiated an indescribable heat.

It throbbed slightly, like a heartbeat, and with each beat, it greedily devoured all the surrounding flames.

Ninety-eight...

Seventy questions...

Thirty dishes...

......

When the last stream of flame was completely devoured, the point of light suddenly expanded and then contracted.

It eventually stabilized and transformed into a reddish-gold shuttle-shaped flame containing boundless light and heat, with swirling winds around it.

The moment the spark condensed, Shen Yu's aura surged dramatically.

A blazing fire, several times more powerful than before, emanated from its body, distorting the air inside the cave and causing the stone walls to glow faintly red.

His tightly closed eyes suddenly opened, and deep within his pupils, it seemed as if two clusters of golden flames were burning.

The Fierce Nether Wind Summoning Technique has now reached its pinnacle!

A surge of power filled Shen Yu's limbs and bones, and he felt an indescribable joy in his heart. He almost wanted to let out a long roar to express the pleasure in his heart.

But considering that this was a place for cultivation by another sect, he ultimately suppressed his surging joy and chuckled softly.

Just then, Wang Xuanxiu's voice came from outside the cave.

"Young friend, the intense heat emanating from within the cave suggests that your superior Daoist technique has reached its zenith?"

Shen Yu straightened his robes, pushed open the cave door, and bowed to Wang Xuanxiu. "I have not failed in my mission. Thanks to the Nine Dragon Mushroom given to me by the senior, I have finally succeeded and have not let the senior down."

Wang Xuanxiu nodded deeply and praised, "Excellent! Young friend, you are truly a prodigy, with extraordinary talent. In my more than a hundred years of cultivation, this is the first time I have ever seen someone cultivate a superior Dao technique to such a high level of mastery at the Qi Refining Realm!"

He stepped forward excitedly and grabbed Shen Yu's arm: "There's no time to lose! Now that your magic is complete, young friend, please come with me to heal your wife at once!"

Shen Yu naturally agreed, and the two set off immediately. Led by Wang Xuanxiu, they soon arrived at another cave on the main peak.

This cave dwelling is also located on a spiritual vein, with abundant spiritual energy. Its interior furnishings are also more exquisite, exuding a sense of tranquility and elegance.

Shen Yu entered the inner room and saw Liu Fengyi and Xie Shiyuan standing solemnly in front of a warm jade bed.

The bed was surrounded by elegant curtains, through which a thin figure could be vaguely seen, and the sound of coughing could be heard continuously.

When Liu Feng saw Shen Yu coming, he unusually did not show any disgust; instead, he seemed somewhat expectant.

Xie Shiyuan stepped forward and bowed deeply to Shen Yu.

Reaching the bedside, Wang Xuanxiu took a deep breath and turned to Shen Yu, "Young friend, success or failure hinges on this moment. The lady's life rests entirely in your hands!"

Although Shen Yu felt that she was well prepared, she couldn't help but feel a little pressure in the face of such a heavy responsibility.

"Rest assured, senior, I will do my utmost to live up to your expectations!"

Seeing Shen Yu's calm expression and firm gaze, Wang Xuanxiu felt somewhat relieved. He patted Shen Yu's shoulder forcefully and said no more.

He then gestured to Liu Fengyi and the other person, and silently withdrew from the cave, leaving only Shen Yu and Yu Jingci.

Shen Yu composed herself and gently lifted the bed curtains.

A woman with a face as pale as paper lay in a brocade quilt, her eyes closed and her brows furrowed.

Yu Jingci seemed to have fallen into a semi-comatose state, completely unaware of Shen Yu's approach, only instinctively letting out painful groans and bursts of violent coughing.

Shen Yu slowly reached out his hand, but before his fingertips even touched Yu Jingci's forehead, a chilling aura, like a venomous snake, rushed over from afar, following the meridians of his arm straight to his heart.

Shen Yu frowned, and the crimson-gold fire seed in his dantian immediately separated a wisp of extremely yang heat, instantly extinguishing the cold current.

"This chilling aura is so domineering? Not only can it corrode its host, but it can also spontaneously attack any living being that approaches?"

Shen Yu's expression darkened. Without further hesitation, he grabbed Yu Jingci's slender wrist and probed her body with his divine sense, beginning to carefully search for the source of the cold energy.

Soon, he discovered some fine, hair-like, yet as hard as ice, deep blue crystals in Yu Jingci's heart, lungs, and other vital areas.

These ice crystals were constantly emitting a chilling, malevolent aura, relentlessly eroding her life force.

Especially the few located near the heart meridian, which are deeply embedded, almost fused with the flesh.
