"Sigh... What a headache."

Watching Shen Qingshuang’s retreating figure, Shen Qingyao shook her head in resignation.

She and Shen Qingshuang were twin sisters. In their childhood, the two of them were incredibly close, doing everything together.

They ate together, slept together, and studied their letters together.

Shen Qingyao still remembered how they would often go to their villa in the Lishui District to gaze out at Jishui Lake, frolicking barefoot along the shore.

Those were their happiest days.

When they grew a little older, they began cultivating the Martial Dao together. Both possessed outstanding innate talent and exceptionally high comprehension. They remained as close as ever, sharing everything with each other.

But all that changed when they turned twenty.

The Shen Family needed someone from the younger generation to take a position in the South City District City Guard Department to solidify the family’s influence there.

The younger generation of the Shen Family was lacking in talent, leaving only the sisters, Shen Qingyao and Shen Qingshuang, as viable candidates for the post at the City Guard Department.

A position at the City Guard Department not only meant constant public exposure but also being bogged down by mundane affairs, both of which would inevitably hinder one’s Martial Arts Cultivation.

Both sisters were proud and ambitious, dedicated to cultivating the Martial Dao, so naturally, neither wanted the position.

But the family had a need, and someone had to step up. Ultimately, the family elders chose Shen Qingshuang to go and make her way in the City Guard Department, while Shen Qingyao would remain with the Shen Family to focus on her Martial Arts Cultivation.

Although Shen Qingshuang didn’t voice any objections to this arrangement, she couldn’t help but harbor resentment.

After all, Shen Qingyao was the older sister, born just a few moments before her.

When the Shen Family needed someone to shoulder the responsibility, making the younger sister step up was indeed hard to justify.

Shen Qingyao had offered to go in Shen Qingshuang’s place, but the family elders had refused.

Ever since then, a subtle rift had formed between the two sisters. Shen Qingshuang spent most of her time in the South City District, rarely returning to the Inner City.

She also seemed to be nursing a secret grudge, pushing herself to cultivate the Martial Dao with even greater diligence. Despite juggling her duties at the City Guard Department with her cultivation, she still managed to keep pace with Shen Qingyao.

Afraid that her Martial Arts Power would be surpassed by Shen Qingshuang, Shen Qingyao naturally didn’t dare to slack off and cultivated relentlessly.

After all, unlike Shen Qingshuang, she had the luxury of cultivating the Martial Dao without distractions. If she were to be surpassed by her sister, wouldn’t she be failing the elders who had invested in her and making herself a laughingstock to Shen Qingshuang?

And so, though neither sister would ever admit it, they were locked in a secret competition, each refusing to fall behind.

From sisters who were once kindred spirits to secret rivals—it was truly a lamentable turn of events.

Now, the marriage alliance with Chen Cheng had once again pitted the two sisters against each other, forcing them into direct opposition.

To be fair, as the older sister who already felt she owed Shen Qingshuang for what had happened before, Shen Qingyao should have been magnanimous and yielded, especially after seeing that her sister seemed fond of Chen Cheng.

But Shen Qingyao had her own troubles. This concerned the next stage of her Martial Arts Cultivation, and she felt she truly had no other choice.

In the Shen Family’s Martial Dao legacy, the Frost Snow Realm was the natural first choice. However, the Frost Snow Realm had its own limitations; one needed frigid, wintry weather to best comprehend it.

In a drought like this year’s, even with her Cold Jade and the newly acquired Snow Silkworm, Shen Qingyao’s progress in comprehending the Frost Snow Realm was still slow.

Furthermore, the Shen Family Ancestor had been steeped in the Frost Snow Realm for many years and even possessed a treasure like the Ice Soul Jade Marrow, yet he was still unable to break through to the Second Layer Realm.

This led Shen Qingyao to consider another path: to simultaneously cultivate the more powerful Sun and Moon Realm.

She hoped that by mastering multiple Realms, she would more easily comprehend the Second Layer Realm in the future and thereby surpass the Shen Family Ancestor.

This was her ambition in her Martial Arts Cultivation, an ambition she would not abandon, no matter what.

Cultivating the Sun and Moon Realm required the fusion of the Star Moon Realm and the Radiant Sun Realm.

The Sun and Moon Realm is comprised of Yin and Yang. Women are aligned with Yin, so it would be easier for Shen Qingyao to cultivate the Star Moon Realm.

The Radiant Sun Realm, however, is aligned with Yang. It requires a man’s Primordial Yang Qi as a catalyst to absorb the Radiant Sun True Fire and begin cultivation.

And this Primordial Yang Qi could, naturally, only be absorbed through sexual union with a man.

Previously, even if Shen Qingyao had known of such a Dharma Gate, she wouldn’t have given it much thought.

After all, with ordinary Dharma Gates, even daily union with a man would yield only a limited amount of Primordial Yang Qi. Worse, indulging in carnal pleasure would damage one’s own vital essence and impede one’s Martial Arts Cultivation—the loss would far outweigh the gain.

But ever since she and Chen Cheng had that encounter with Le Wuji at the Cold Crow Village Black Market and accidentally obtained the *Sutra of Ultimate Bliss*, the idea of absorbing Primordial Yang Qi had once again taken root in Shen Qingyao’s mind.

Although the Sutra of Ultimate Sect was a Demon Sect, the Dharma Gate described in the *Sutra of Ultimate Bliss* was highly effective and wouldn’t harm one’s vital essence.

Shen Qingyao had previously shown the *Sutra of Ultimate Bliss* to the Shen Family Ancestor, who had confirmed this point.

The Shen Family Ancestor had also mentioned that if two people comprehended the Sun and Moon Realm together, the woman could absorb Primordial Yang Qi while the man could absorb Primordial Yin Qi. This would allow them to achieve Yin Yang Unite, benefiting both partners.

Even if they couldn’t fully comprehend the Sun and Moon Realm, as long as the woman cultivated the Star Moon Realm and the man cultivated the Radiant Sun Realm, they could unleash a portion of the Sun and Moon Realm Power by using them in unison—enough to crush any other First Layer Realm.

This was the profound mystery of the Yin Yang Realm and Yin Yang Unite.

And so, the thought of finding a talented young man to cultivate with took hold in Shen Qingyao’s mind.

Of course, it had to be someone she was genuinely fond of. Only with mutual affection and a perfect blending of minds, like milk and water, could their Yin and Yang achieve ultimate harmony.
