Years and years of water had thoroughly dyed the stones black, with stalactites adorning every corner of the cave. The dark green moss clinging to them emitted a dim glow, making this place appear more eerie and mysterious.

You Su turned his back, leaning against the stone wall to rest. After the seemingly endless battle just now, he appeared somewhat exhausted. Despite being adept at the Dual Cultivation Skill, facing Ji Xueruo, who was gradually getting to her peak and turning completely wild, he found himself somewhat powerless.

Truly, as the saying goes, "snake nature is inherently lewd," the snake demons are terrifying indeed...

In the same cave, surrounded by the same enchanting spring scenery, he recalled the bits and pieces with his junior sister. He initially believed that the allure hidden beneath her delicate and unruly facade was just fleeting, but now he realizes that this might be the side of her unknown to others.

He suddenly began to miss the power of the True Yang Sword Nurturing Spell. Ever since he discovered it enhanced his Yang Fire, he hadn’t practiced it again. He always prided himself on being young and vigorous, but now he knows why the world says there’s only a bull that gets exhausted, not a field that gets worn out.

No wonder Book Mountain Pavilion gifted him this Sword Nurturing Spell... it was intended to prepare him for a shameless life with his junior sister.

Behind You Su, Ji Xueruo was sitting cross-legged on the ground, covered in a black robe, her demeanor refined and dignified. If not for her flushed cheeks and slightly disheveled hair, one would hardly imagine that she had been through crazy moments just now.

On her fair neck, faint white snake patterns emerged, and her body was enveloped in dense black energy, which was all the Divine Blood she had forced out from her body.

Once the black mist completely disappeared, she slowly opened her eyes, and in those beautiful eyes, there were snake-like vertical pupils—cold and dangerous. However, in an instant, they returned to normal, becoming clear eyes with distinct black and white.

"Whew..."

Ji Xueruo let out a long breath of foul air. Her body had undergone too many unimaginable changes in a short time, making the rejuvenated her feel much more refreshed.

Earlier, the color of her sister’s Demon Pill was already very pure; now the new Demon Pill You Su created for her was not only completely white without a trace of impurity but also significantly larger than before, evidently a rare Top-Grade Demon Elixir.

"Thank you..." Ji Xueruo whispered softly in thanks.

You Su’s ears twitched; he didn’t turn his head, only uttered a gentle acknowledgment.

She glanced at You Su’s lonely and desolate back, inexplicably feeling some pity for the blind man curled up in the corner.

It seemed as if she, sitting here cross-legged after the event, was the cold and callous buyer in a spring trade.

This Dual Cultivation appeared to be You Su taking advantage of her, but by its development, she had long since taken the dominant role. Under the dual stimulation of body and psyche, she had lost her composure, unable to discern whether it was to grind more to enhance the Demon Pill... or to indulge in her own desires, unable to extricate herself...

He must be very exhausted, right?

"Ahem."

Ji Xueruo coughed twice to cover her embarrassment; she wanted to speak proactively but didn’t know where to start, pondering for a while before suddenly saying:

"Lingruo was right; you’re quite formidable."

?

You Su was bewildered; even if sisters were close, they wouldn’t exchange such details, right?

"Not too shabby..." You Su awkwardly laughed twice, unable to accept such praise from his sister-in-law with equanimity.

"What are you thinking?" Ji Xueruo’s mind worked quickly; hearing the tone of You Su, she realized she had misspoken, quickly added, "I meant your constitution is formidable. Lingruo said you have the Heavenly Furnace Constitution, a top-tier body for Dual Cultivation, capable of reconstructing Demon Pills. I had never heard of it before, merely thought it was a lie Lingruo fabricated for you. But unexpectedly... it truly is such a formidable physique."

Heavenly Furnace Constitution?

You Su quickly understood the intricacies. To avoid exposing the Power of Tai Sui, his junior sister made up this ’Heavenly Furnace Constitution’.

"I merely said this constitution was okay, not particularly formidable. Compared to those Innate Dao Bodies, it’s not worth mentioning. Otherwise, what did Miss Ji think I was pondering?"

Upon hearing this, Ji Xueruo scowled, thinking this hypocrite was merely posing as a gentleman, ironically sneered:

"Nothing much, the constitution is indeed okay, but alas, this person is somewhat inadequate."

You Su slightly raised his eyebrows; being mocked by a woman for being inadequate is one of the greatest taboos for a man; thus, he retorted:

"Miss Ji might have forgotten the screams echoing throughout the cave just now, which I couldn’t suppress even by covering. If we were discovered, Miss Ji would bear full responsibility."

Ji Xueruo instantly opened her eyes wide, feeling the warmth of You Su’s palm still by her lips, taking a deep breath, said:

"You were pierced by a needle, wouldn’t you scream in pain?"

"Miss Ji’s words make sense; next time I am pricked, I will also scream ’Ah ah’ in pain." You Su replied smoothly, unperturbed.

"You!"

Ji Xueruo was so incensed that her chest heaved, wanting to get up to confront You Su, only to find intense soreness and limpness in her lower body, with some lingering moisture, forcing her to lean weakly against the wall, unable to stand.

She silently punched the stone in frustration at her impotence; her charming face instantly turned cold and noble, solemnly stated:

"No more arguing with you, forget about it! Never mention it again! Everything agreed upon beforehand still stands, I will not obstruct you and Lingruo, but you and I shall not meet again!"

"As it should be."

You Su said no more; he knew it was the proud girl’s self-esteem at work, caught in the grip of whether to be angry or grateful.

Thus, after a moment of silence between them, You Su tentatively asked:

"Has Miss Ji fully recovered?"
