Yang Guo: I'm invincible in the opening battle against Aunt Guo!

in the room.

Yang Guo and Lu Wushuang sat cross-legged on the bed, their palms touching.

The internal energy of the Nine Yin Manual flowed out of Yang Guo's body like a trickle and slowly flowed into Lu Wushuang's body.

The extremely yin and gentle internal energy flowed through her meridians, leaving behind pure true energy to nourish each acupoint it passed through.

The Yin-Yang Harmony Chapter's mental technique quietly circulated, and the two people's internal energies formed a cycle within their bodies, one Yin and one Yang, nourishing each other.

"Hmm..." Lu Wushuang hummed softly, her face flushed.

She could clearly feel her cultivation level steadily improving, and the barrier of the early second-rate realm began to loosen.

In the next room, Li Mochou suddenly opened her eyes.

She was sitting cross-legged, practicing her internal energy, when she was startled by a familiar fluctuation of internal energy—it was the aura of the "Yin Yang Harmony Chapter"!

Moreover, judging from the intensity of the fluctuations, Yang Guo is currently engaging in a profound exchange of internal energy with Lu Wushuang.

Li Mochou's lips curled into a cold smile.

This little girl has finally embarked on this path as well.

She wasn't surprised.

Ever since that night in the ancient tomb's stone chamber, when she and Yang Guo practiced dual cultivation to heal their injuries and greatly improved their cultivation, she knew that Lu Wushuang would eventually face this day.

"Master... what's next door...?" Hong Lingbo asked softly from another bed.

Li Mochou got out of bed and said calmly, "It's just cultivation. You can go back to sleep."

"Yes……"

Li Mochou pushed open the door and walked straight to the doorway of the middle room.

She didn't knock; she just pushed the door open and came in.

Inside the room, Yang Guo and Lu Wushuang sat facing each other, their palms touching.

In the candlelight, Lu Wushuang's face was flushed and sweat was beading on his forehead, clearly indicating that he had expended a great deal of internal energy.

Upon seeing Li Mochou, Lu Wushuang exclaimed, "Master!" and instinctively tried to stop her practice and get up.

"Don't move." Yang Guo pressed her hand down and looked at Li Mochou. "Mochou, you're here?"

Li Mochou's phoenix eyes swept over the two of them, and the smile on her lips deepened:

"What, you didn't even call me to cultivate? Last time in the ancient tomb, you promised to help me break through the Grandmaster threshold."

As she spoke, she walked straight to the bedside and sat down, unabashedly unbuttoning the outer hem of her Taoist robe to reveal the moon-white inner garment underneath.

His movements were natural and graceful, as if he were just preparing for a normal meditation.

Lu Wushuang's cheeks flushed even redder, and she dared not look at her master.

Yang Guo smiled: "You've come at the right time. Wushuang's cultivation is still shallow, and it's a bit difficult for her to withstand the Nine Yin Internal Energy alone. If you join us, the three of us can cultivate together, making the cycle more stable, which will benefit everyone."

"Then what are we waiting for?" Li Mochou held out her palm. "Let's begin."

She was a bold person by nature, and having already had physical intimacy and dual cultivation with Yang Guo, she naturally wouldn't act coy or pretentious.

Moreover, she couldn't be more eager for such an opportunity to quickly improve her cultivation level.

Yang Guo extended his other hand and placed it against Li Mochou's palm.

The moment the tentacles touched, three streams of internal energy began to circulate simultaneously.

Yang Guo acted as a mediator, and the "Yin Yang Harmony Chapter" mental technique was fully activated.

His internal energy acted like a bridge, connecting Li Mochou and Lu Wushuang, guiding their true energy to form a perfect cycle.

It flowed out of Yang Guo's body, split into two streams, entered the meridians of the two women, circulated throughout their bodies, and then merged back.

A strange feeling welled up in the hearts of the three.

Li Mochou could clearly sense the immaturity and purity of Lu Wushuang's internal energy, and she could also sense the vastness and purity of Yang Guo's internal energy.

What made her even more uneasy was the intimacy brought about by the fusion of their inner strength.

She could almost sense Yang Guo's focus and gentleness at that moment, as well as Lu Wushuang's deep reliance and joy.

But she quickly regained her composure and focused all her energy on circulating the Ancient Tomb Sect's internal energy cultivation method.

This was her real purpose in coming here—to achieve a breakthrough!

The threshold of becoming a Grandmaster that had blocked her for many years began to loosen violently under the impact of the three people's internal energy circulation.

She could feel the cracks at the bottleneck widening; if she could just hold on for a few more hours…

Time slips away quietly.

Lu Wushuang was the first to give out.

Her cultivation level was the lowest. Although Yang Guo had expanded and nourished her meridians with the Nine Yin Manual, the long-term high-intensity cultivation still caused her to be mentally exhausted.

"Brother Yang... I can't go on..." Her voice was weak, and she collapsed onto the bed, falling into a deep sleep.

Yang Guo finished his practice, gently laid her down, and covered her with the blanket.

Li Mochou opened her eyes, a hint of disappointment flashing in them—the sense of breakthrough that had been within reach just moments before vanished as the cycle was interrupted.

"Her cultivation is still shallow; she can only last for an hour at most." Yang Guo looked at Li Mochou. "How do you feel?"

"Just one step away." Li Mochou's tone was filled with resentment. "The threshold of becoming a grandmaster is so close, yet I can never cross it."

Yang Guo pondered for a moment and said, "Then we can continue our cultivation separately."

Li Mochou's phoenix eyes lit up: "Now?"

"Now," Yang Guo nodded, "Wushuang is asleep, this is the perfect spot."
