201: Undercurrents surge, the Hou Dan refines the body.

Instead, Lin Xuan activated the "cloud piercing shuttle," a top-tier Spiritual Artifact obtained from the ancient palace that combined stealth and speed, which transformed into a nearly imperceptible stream of light and sped towards the "Thunder Roar Mountain Range," where the Gongsun Family was located.

The space inside the shuttle was not spacious, and the four sat facing each other.

Gongsun Yu snuggled beside Lin Xuan, her little face lacking its usual liveliness and carrying more worry and fear for her mother's safety.

Su Wanqing sat with her eyes closed, regulating her breath; moonlight flowed around her, and her aura became increasingly cold and sharp.

She was constantly honing herself, preparing for the upcoming battle, and even for triggering the Nascent Soul Heavenly Tribulation.

Qu Feiyan played with the Nascent Soul demonic core obtained from the Golden Scaled Hou, a glimmer in her charming eyes, wondering what she was plotting.

"System, scan the exterior of the cloud piercing shuttle. Is there any tracking mark or surveillance?" Lin Xuan thought.

The Guixu Cult had devious methods; he had to be on guard.

【Scanning... No external tracking marks found. Detected three weak Divine Senses sweeping from a hundred miles away, with intensities ranging from Late Golden Core Stage to Early Nascent Soul Stage. The sources are suspected to be the Liu Family of Tianshu City and two unknown parties. They have been blocked by the cloud piercing shuttle's concealment Formation.】

Sure enough, there were tails.

A cold light flashed in Lin Xuan's eyes.

He did not alert the enemy, but instead maximized the cloud piercing shuttle's concealment performance and slightly deviated from the straight path.

"Big Brother Lin, can we... successfully save Mother?" Gongsun Yu raised her head, her eyes slightly red, her voice trembling.

Lin Xuan held her slightly cool little hand, and his primal nascent soul power gently flowed over, soothing her uneasy mind.

"Don't worry. Since we are going, we will definitely bring your mother out safely."

His tone was calm and firm, carrying a convincing power, "Anyone who dares to hurt your Family will have to pay the price."

Feeling the warmth and firmness from his palm, the fear in Gongsun Yu's heart was dispelled quite a bit; she nodded vigorously, holding Lin Xuan's hand even tighter.

"Tsk, little girl, don't worry."

Qu Feiyan put away the demonic core and stretched lazily, revealing her graceful curves, "With your Big Brother Lin here, along with me and your Senior Sister Su, a mere infiltrated Gongsun Family can't stir up any trouble. Maybe you can even take the opportunity to take over the Family and provide more resources to our Master Lin in the future, right?"

Her words were teasing, but also carried powerful self-confidence.

Su Wanqing also opened her eyes, her cold gaze falling on Gongsun Yu, and she nodded slightly: "Focus your heart and calm your spirit; do not panic. The matter of saving people requires calm planning."

"Mm! I will listen to my Senior Sisters!"

Gongsun Yu felt the care and support of the two sisters, and a warm current surged in her heart; she nodded heavily.

Lin Xuan looked at the three women, feeling settled in his heart.

After pondering for a moment, he said to Qu Feiyan: "Feiyan, how do you plan to dispose of that Golden Scaled Hou demonic core?"

Qu Feiyan's charming eyes turned, and she smiled: "This demonic core's energy is violent; taking it directly is too risky. However, if I carefully refine it with my Blood Lotus Demonic Art supplemented by a few yin-attribute spiritual materials, extracting its purest demon essence, I can refine a few 'blood lotus Demon Essence Pills,' which have miraculous effects for breaking through the Nascent Soul Bottleneck. Of course, this takes time."

Lin Xuan nodded; Qu Feiyan had her own unique insights into alchemy and the use of Demonic Techniques.

"Leave this matter to you. However, before arriving at the Gongsun Family, we need to improve our strength as much as possible."

He turned his gaze to Gongsun Yu, "Xiao Yu, your cultivation has reached the Middle Stage Bottleneck. For this rescue mission, every bit of extra strength means a greater chance of success. I have a method that can borrow some of the gentle demon power from this demonic core to perform Body Tempering and condense your core, helping you break through to the Late Stage. Are you willing to give it a try?"

Hearing this, Gongsun Yu's eyes immediately shone, and she said without hesitation: "I am willing! Big Brother Lin, as long as I can help, I am willing to do anything!"

"System, deduce a plan to assist Gongsun Yu in safely breaking through to the Late Golden Core Stage using the aftereffects of the Golden Scaled Hou demonic core."

【Deduction in progress... The plan is feasible. The Host can use primal nascent soul power as a guide to build a 'Primal Spiritual Vortex,' stripping away the gentle demon power and thunder aura from the surface of the demonic core, and guiding it to scour the target's Meridians, stimulating the transformation of the Golden Core. It needs to be combined with 'Meridian Protecting Pills,' 'Spirit Calming Incense,' etc. The success rate is 89%. Risk: There may be a feeling of swelling and pain in the Meridians during the process.】

"Good."

Lin Xuan did not hesitate any longer, letting Qu Feiyan take out the demonic core while he took out the relevant Medicinal Pills and spiritual incense.

The space inside the cloud piercing shuttle was limited, so he had Gongsun Yu sit cross-legged in front of him, while he sat behind her, pressing his palms against her back.

"Focus your mind and guide the circulation of my power."

Lin Xuan gave a low drink; his primal nascent soul moved slightly, and his pure, vast power, carrying the aura of embracing all things, slowly poured into Gongsun Yu's body.

At the same time, he stirred the demonic core floating to the side; strands of gold-tinged purple energy, containing pure demon power and thunder aura, were stripped away and merged into the primal power, beginning to circulate along Gongsun Yu's Meridians.

"Ugh..."

As the massive energy entered her body, Gongsun Yu let out a muffled groan, feeling her Meridians swell and sting.

But she gritted her teeth and exerted all her strength to circulate her Family's thunder technique, guiding this mixed force to scour her Golden Core.

Su Wanqing and Qu Feiyan protected them from the side, their expressions focused.

Su Wanqing's fingertips were surrounded by cold air, ready to deal with any accidents; Qu Feiyan observed the energy flow, ensuring its balance.

Time passed slowly.

Fine beads of sweat seeped from Gongsun Yu's forehead, her little face turning red and then pale, but she kept her mind focused.

The Golden Core in her Dantian, under the continuous infusion of pure energy and the combing of the primal power, began to spin violently; purple lightning swirled on its surface, its light growing brighter, and its volume slowly increasing, steadily advancing towards the Late Golden Core Stage!

Lin Xuan sank his mind, precisely controlling the energy output.

He could feel that Gongsun Yu's Foundation was even more solid than he had expected; this Breakthrough was a matter of course.

Several hours later, the cloud piercing shuttle had quietly traveled thousands of miles.

A slight humming sound suddenly erupted from Gongsun Yu's body; her Golden Core suddenly expanded in size, the thunder patterns on its surface became clearer and more complex, and the spiritual power fluctuations it emitted had risen by a level!

Late Golden Core Stage, achieved!

Lin Xuan slowly withdrew his power, his face looking slightly tired, but his eyes held gratification.

Gongsun Yu excitedly opened her eyes, feeling the power in her body that had nearly doubled, and turned to hug Lin Xuan excitedly: "Big Brother Lin! I succeeded! Thank you!"

The girl's soft body entered his arms, carrying a faint fragrance and joyful tremors.

Lin Xuan smiled slightly and gently patted her back: "It is because your own Foundation is solid."

Su Wanqing looked at the two embracing, her cold eyes softening.

Qu Feiyan hummed sourly: "Yo, hugging already? Why didn't I get this treatment when I was putting in the effort to refine the demonic core?"

Gongsun Yu realized her impropriety, blushed, and let go of Lin Xuan, bowing respectfully to Qu Feiyan and Su Wanqing: "Thank you, Senior Sister Su and Senior Sister Qu!"

"Alright, we're sisters, no need to be polite."

Qu Feiyan waved her hand, but her lips carried a smile.

After this episode, the atmosphere in the shuttle relaxed a lot, and Gongsun Yu's confidence increased significantly.

Another half a day passed, and the cloud piercing shuttle slowly decelerated.

Through the porthole, one could vaguely see the undulating mountain range shrouded under faint thunderclouds in the distance—the Thunder Roar Mountain Range, where the Gongsun Family had lived for generations.

A feeling of impending storm quietly permeated the hearts of the four.

Lin Xuan looked sharply at the mountain range, his Divine Sense like invisible tentacles, cautiously extending forward.

The Gongsun Family instance had officially opened, with the dual goals of saving people and destroying the Guixu Cult's conspiracy awaiting them.

And Gongsun Yu, who had undergone Body Tempering with the Golden Scaled Hou demonic core, would also face the Family's sudden change with a brand-new posture.
