172: Chapter 172 What kind of expression did Master actually have?

And at this moment, what poured into his body was the purest primordial yin!

It was the most fundamental and essential power of a female Cultivator!

Those forces of primordial yin rushed into his Dantian and were instantly sensed by his Yin-Yang Dao Foundation—

Boom!

The Yin-Yang Dao Foundation let out a roar, as if a long-starved Taotie had encountered a delicacy,

and began to absorb that primordial yin frantically!

Atop the Dao Foundation, the black and white colors suddenly lit up, their radiance dazzling and eye-catching!

The Yin and Yang fish pattern rotated slowly; with every revolution, it devoured a massive amount of primordial yin energy!

And that primordial yin energy seemed endless; as one batch was devoured, another immediately surged in!

Ye Changge was completely stunned.

In all his time practicing the Yin Yang Creation Art, he had never encountered such a situation.

How could there be such a massive amount of primordial yin within Nangong Zili's body?!

Moreover, it was a hundred or even a thousand times more potent than that of an ordinary virgin!

Ye Changge was also extremely puzzled.

Nangong Zili was clearly at the Core Formation Early Stage; even if her primordial yin was potent, it shouldn't be this exaggerated, right?

Since practicing the Yin Yang Creation Art, he had engaged in Dual Cultivation many times with his wives and concubines like Lu Shiyin, Lu Shiqing, and Liu Yiyi, so he already had a good sense of the quality and quantity of a woman's primordial yin.

But the primordial yin pouring into his body now, in its purity and majesty, far exceeded anything he had experienced before—it was even several times more potent than the Spiritual Qi left to him by that Core Formation female Cultivator, Meng Qingcheng!

"Could it be... that Nangong Zili is some kind of Special Spiritual Constitution?"

A flash of inspiration struck Ye Changge's mind.

He recalled that accident with Meng Qingcheng; although she hadn't said it explicitly, a strand of extremely pure Spiritual Qi had remained in his body afterward, and it was that very energy that helped him forge a perfect Dao Foundation during his Foundation Establishment.

And the abundance of primordial yin in this Spider Gu Envoy before him was simply inconceivable; it was definitely not something an ordinary Core Formation Cultivator could possess.

"Could there be some innate treasure within her body?"

Ye Changge speculated in his heart but had no time to investigate further.

Because that primordial yin energy was continuously pouring into his body as he performed the Flipping Phoenix Technique!

As each wave of primordial yin entered his Dantian, the Yin-Yang Dao Foundation spun frantically, the black and white Yin and Yang fish pattern rotating faster and faster.

The light grew brighter and brighter, as if parched earth meeting sweet rain, greedily devouring every shred of power!

Ye Changge dared not be negligent and pushed the Flipping Phoenix Technique to its limit!

This secret technique was originally a high-level method that used the path of Dual Cultivation to guide the blending of Yin and Yang for mutual benefit; now, under his full operation, a mysterious spiritual power whirlpool seemed to form between the two.

The primordial yin energy within Nangong Zili's body rushed forth like water from a burst dam!

Time passed slowly.

After an unknown amount of time—

The aura around Ye Changge's entire body suddenly skyrocketed!

A majestic wave of spiritual power swept out from his body, forming a small Spiritual Qi vortex around him!

The vortex spun faster and faster, growing larger until it finally exploded with a "boom"!

Ye Changge felt as if some barrier in his Dantian had been smashed through in one go, and his cultivation level leaped directly to the Foundation Establishment Fifth Layer as naturally as water flowing in a channel!

He opened his eyes, which were shining with brilliant light, his face full of disbelief.

He had made a Breakthrough just like that?

According to his original cultivation speed, even with the aid of Dual Cultivation with Lu Shiyin, it would have taken at least half a year to a year of bitter cultivation to break through from the Foundation Establishment Second Layer to the Fifth Layer.

Yet now, after less than an hour of Dual Cultivation with Nangong Zili, he had actually broken through three layers in a row, jumping straight to the Foundation Establishment Fifth Layer!

The entire process was as simple as drinking water!

Ye Changge looked down at Nangong Zili beneath him.

By now, she had long since lost her previous cold arrogance and resistance; her eyes were tightly shut, her brow slightly furrowed, and her cherry lips were parted as uncontrollable whimpers escaped from deep within her throat.

Her jade-white body was flushed with an enticing pink, appearing breathtakingly seductive under the green light of the Talisman Array.

That appearance would make anyone's blood boil with passion.

Ye Changge took a deep breath and was about to continue—

Suddenly, he noticed two gazes landing on him.

He turned his head to look.

One came from Xiao Caiyue.

At this moment, Xiao Caiyue was sitting cross-legged not far away, her hands forming seals to maintain the Talisman Array that enveloped the three of them.

She had been focused, but now her head was slightly turned, her gaze falling on the place where Ye Changge and Nangong Zili were joined, a faint blush appearing on her cheeks.

She had naturally sensed the spiritual power fluctuations produced when Ye Changge broke through just now.

She sighed inwardly; her husband was indeed extraordinary, to be able to break through so quickly by Dual Cultivating with a Core Formation True Person.

But when she subconsciously followed the aura and saw the posture Ye Changge had assumed...

Her body nearly swayed, and even the hand seal she was holding almost faltered.

That posture...

Xiao Caiyue cursed inwardly: "lecher!"

Her husband was usually as gentle as jade and well-mannered, but how could he have so many tricks when it came to these matters of the bedchamber?

He had actually posed Nangong Zili in such a shameful manner,

her waist arched into a breathtaking curve,

exposing everything without reservation!

Xiao Caiyue felt her cheeks burning and quickly looked away.

But after only a few breaths, her gaze involuntarily drifted back.

She had to admit...

The current Nangong Zili was truly alluring.

That white body flushed with enticing pink, her skin as lustrous as fat, her curves exquisite and well-defined,

especially those legs posed in such an extended way, showcasing a woman's softness and charm to the fullest.

As Xiao Caiyue watched, she actually developed a strange sensation—

a desire to step forward and personally touch that pink-tinged skin to feel its texture.

As soon as this thought arose, she was jolted awake and spat at herself inwardly.

Xiao Caiyue, oh Xiao Caiyue, what kind of wild thoughts are you having?!

She took a deep breath and tried to pull her gaze back, focusing on maintaining the Formation.

But that image was etched into her mind like a brand, impossible to dispel.

The other gaze came from Su Xiaotang.

She was huddled at the edge of the Formation, hands covering her mouth, but her eyes were wide open, staring intently at Ye Changge and Nangong Zili.

Her cheeks were so red they almost seemed to drip blood, and even her ears and neck were stained with a layer of pink.

Was this... Dual Cultivation?

Su Xiaotang's heart pounded like a drum, her mind in a state of chaos.

Back at the Five Gu Sect, she had secretly flipped through some ancient texts about Dual Cultivation Techniques while her Revered Master was away.

The pictures and words in those books had made her so ashamed at the time that she had quickly closed them and never dared to look again.

But now, a living scene was right before her eyes.

And... and Revered Master actually had that kind of expression!

Su Xiaotang had never seen Nangong Zili show such an expression—

brow slightly furrowed, eyes half-closed, cherry lips parted, with low moans overflowing from deep within her throat; she looked both pained and blissful, with an indescribable charm.
