Sparks ignite immortal shadows, a single thought determines destiny.

"Heavenly Stars, heed my command! With my True Fire, Refine This Immortal God!"

Lin Yuan's voice was no longer his usual gentle or teasing tone, but rather filled with a chilling, murderous aura, a build-up of resentment from his failed Breakthrough.

Before his words even finished, the Star Curtain above the entire Tingfeng Courtyard completely transformed into a sea of dark blue flames!

The Earth Core Nether Fire was originally a spiritual flame of heaven and earth. Lin Yuan re-arranged the Formation, using the Earth Core Nether Fire as the Formation Eye, drawing Star Power from the Heavenly Stars as fuel, turning the entire grand Formation into a terrifying Pill Furnace!

Under the amplification and guidance of the Zhou Tian Xing Dou Great Array, its power was magnified by more than ten times! Every wisp of starlight became the most efficient fuel, and every Formation pattern became a bellows to enhance the power of the flame waves!

The dark blue flame waves were no longer just burning; they condensed into countless flame needles as fine as ox hair, carrying a terrifying aura that could penetrate the Divine Soul, and surged towards Situ Piaomiao from all directions!

"Madman!"

On Situ Piaomiao's perpetually icy face, a look of horror finally appeared.

She had never dreamed that a junior at the Foundation Establishment Stage could combine Formations, spiritual fire, and his own magical power to such an inconceivable extent. This was no longer a simple Formation; it was a fiery furnace tailor-made for her!

She dared not be negligent in the slightest, and the ancient mirror in her palm once again shone brightly, attempting to decipher the Formation as before.

However, the unfailingly effective Formation Breaking Profound Light, upon touching the dark blue flame waves, made a sizzling sound like hot oil meeting water, and its light was eroded and swallowed at a visible rate!

"How can this be?" Situ Piaomiao's mind was greatly shaken.

The Formation Breaking Profound Light Mirror specialized in breaking all Restrictions and Formations in the world, relying on analyzing and dissolving the spiritual power structure of the Formation itself. But Lin Yuan's move was ruthless because he forcibly integrated the unreasonable physical energy of the Earth Core Nether Fire into every aspect of the Formation's operation.

This was like bringing a master key that could open all locks in the world. But the other party hadn't locked it at all; they had directly welded the door shut with molten steel!

What good was your key then?

Lin Yuan's figure flickered in and out of sight within the sea of fire, his voice filled with the glee of a cat playing with a mouse, "Fairy Situ, my Tingfeng Courtyard has been newly renovated, and I've specially prepared a 'Earth Fire Heat Therapy' Supreme gift for you, no extra charge. Don't you think my service is thoughtful?"

However, he secretly warned himself that having too many Nascent Soul Cultivators around recently had caused him to relax his guard, almost leading to a sneak attack. He must remember in the future never to be careless, as he only had one life.

Situ Piaomiao's face was ashen. She no longer tried to break the Formation, but instead activated all her magical power. Streaks of destructive Sword Qi surrounded her, forming an impenetrable Sword Qi shield that temporarily blocked the dark blue fire needles.

"Heavenly Stars, strangle!"

The boundless sea of fire instantly contracted, and three hundred sixty-five stars manifested. Each star dragged thick dark blue flame wave chains, forming a net that descended upon Situ Piaomiao!

Situ Piaomiao's expression changed again. She could feel that once her magical power was exhausted, it would be her death!

The Formation Breaking Profound Light Mirror in her hand had now become the hottest potato. Although this treasure was powerful, activating it also consumed a terrifying amount of magical power. Maintaining it until now, nearly half of her Mirror Image Clone's magical power had been depleted.

"Lin Yuan!" Situ Piaomiao let out a sharp shriek, her voice filled with unwillingness and resentment, "The secret of Immortal flesh and blood far exceeds your imagination! You are nothing but an ant on the chessboard about to be crushed!"

"Oh? Is that so?" Lin Yuan's voice drifted over leisurely, "But at least for now, you, this self-proclaimed clever ant, are about to be crushed by me first."

He stopped wasting words and pushed his Divine Sense to the extreme!

The fiery star net suddenly tightened, and the dark blue flame wave chains rattled as they squeezed into Situ Piaomiao's Sword Qi shield, letting out a groan of unbearable strain. Spiderweb-like cracks instantly spread across it.

"You..."

Situ Piaomiao's cold, pretty face was finally replaced by terror. She could feel that the magical power of her Clone was being eroded by the Formation at a terrifying speed.

"You... you can't kill me!" she shrieked, her voice trembling slightly.

"Hmm? Can't kill?" Lin Yuan's voice came from the sea of fire, with a hint of playfulness, "Give me a reason. If you explain it well, I might consider leaving you a complete corpse."

Situ Piaomiao's breathing was rapid. To save this Mirror Image Clone, which had cost her countless efforts, she could only throw out her last trump card: "I know how to use the dao seed in Immortal flesh and blood... to Break through Bottlenecks!"

These words, like a clap of thunder, exploded in Lin Yuan's heart.

He had just experienced the pain and unwillingness of failing to Break through to the Golden Core, and the indestructible Bottleneck was still fresh in his memory. Hearing these words now, a monstrous wave immediately surged in his heart.

This dao seed might truly be his opportunity.

"Tell me about it?" Lin Yuan's voice remained calm, but the contracting fiery star net eased slightly.

Seeing this, Situ Piaomiao felt a little relieved and quickly said, "Immortal flesh and blood are rare treasures condensed from the essence of the Dao and Dharma of Upper Realm Immortals after their demise. The dao seed contained within holds a trace of the Upper Realm's Law. With our Lower Realm Cultivators' weak Divine Souls, it's impossible to directly refine it. Forcibly absorbing it would only lead to the collapse of one's Divine Soul!"

She took a breath and continued, "But through the research of my master and me, the dao seed can be used as a seed, first planted within another person's body, using their flesh, blood, and Divine Soul as soil to nurture and cultivate it, waiting for the dao seed to sprout and initially Fuse with the host!"

"At that time, a special Secret Technique can then be used to extract the sprouted dao seed along with the host's essence, Qi, and spirit, and absorb it into one's own body. This bypasses the barrier of Law and allows for a successful Breakthrough of the Bottleneck!"

Lin Yuan listened to her words, his gaze fixed on her, "What kind of Secret Technique?"

"You let me go... and I'll tell you!" Situ Piaomiao gritted her teeth.

"Hehe."

Lin Yuan grinned, his smile full of mockery, "Do you take me for a three-year-old child?"

He suddenly formed a Hand Seal, and the dark blue flame waves surged and roared again, the terrifying high temperature causing Situ Piaomiao's hair tips to curl.

Her Sword Qi shield, under the scorching of the flame waves, finally let out a "crack" and completely collapsed.

"Bind!" Lin Yuan low-roared.

Just as Situ Piaomiao thought she was about to be swallowed by the sea of fire, a rope refined from DragonJiao Dragon Tendons silently emerged from the shadows beneath her feet, like a living spiritual snake, instantly binding her, whose magical power was almost exhausted, tightly.

With the essence binding rope on her, her remaining magical power was immediately sealed, and she could no longer use even a sliver.

Lin Yuan's figure walked out of the sea of fire, pacing to her front, looking down at her, and gently tapped the essence binding rope with his fingertip, making a dull sound.

"If what you say is true, that using a Secret Technique can Break through the Bottleneck, then... your main body's Cultivation shouldn't be at the Middle Nascent Soul Stage; it should at least be at the Late Nascent Soul Stage!"

"There must be a trick!" Lin Yuan said, his gaze sharp, enunciating each word.
