Mortal: Starting in a chaotic starry sea, I can upgrade everything.

Zhou Yuan let out a soft hum, and said indifferently, "The sect is currently at a low point. You should think more long-term."

"This person's cultivation has reached the Pseudo-Core stage, and he is expected to form his Core within twenty years. For both personal and practical reasons, the Miaoyin Sect must be on good terms with him, and even try to win him over."

Zhuo Ruting looked on incredulously and asked in a trembling voice, "Core Formation? Master, this person can't be that fast, can he?"

Zhou Yuan sighed softly, her eyes filled with complex emotions: "Who can say for sure about things like this?"

Her thoughts were churning, recalling the scenes of Jiang Yu breaking her illusion and ignoring her seductive arts, and seeing how he remained neither humble nor arrogant in front of her.

Especially after demanding the secret technique of dual cultivation, he even dared to secretly peek at her...

If it were any ordinary Foundation Establishment cultivator, she would have slapped them to death long ago.

But it was Jiang Yu who she couldn't see through or control.

............

Jiang Yu bid farewell to the Miaoyin Sect, his body enveloped in spiritual energy, and he flew through the air.

The young man in black robes looked smug, and before long, he flew straight back to his cave.

This trip to the Myriad Sounds Sect yielded the Yin-Yang Reincarnation Technique, a fortuitous opportunity that made him feel the trip was worthwhile.

As soon as you step into the cave, a faint fragrance of spiritual herbs wafts over you.

It lingers around the tip of the nose, refreshing and delightful.

Inside the jade chamber, Yuan Yao and Yan Li were busy at work. With a flick of their fingertips, several Rainbow Spirit Grasses flew out.

The next moment, swarms of gold-devouring insects rushed in, surrounding the spirit herb and feeding on it, the soft rustling sound echoing gently in the room.

Jiang Yu casually swept his divine sense across the scene before him, took in the whole view, and couldn't help but chuckle. He called out, "Yuan Yao, Yan Li, come here."

Upon hearing the sound, the two women immediately stopped what they were doing and quickly walked out of the insect chamber.

"Young master, you're back!"

The two sisters bowed together.

Looking up, she saw Jiang Yu holding a book with an ancient pattern in his hands, and a smile that he could hardly hide on his face. She was immediately filled with doubt.

"Alright, I told you all long ago that you don't need to go through such formalities when you see me."

Seeing this, Jiang Yu waved his hand casually, speaking in a friendly tone.

The voice just fell.

He then handed the Yin-Yang Harmony Mantra to Yanli, his senior sister.

"Take a look at this technique. It is the Yin-Yang Harmony Technique, a superior dual cultivation method that allows men and women to complement each other. The effects of practicing it are excellent."

Yuan Yao and Yan Li were stunned and stood there dumbfounded.

The two followed instructions and probed the object with their divine senses. After a brief examination, they instantly understood the essence of the technique.

Practicing this technique requires the merging of one's energy and concerted effort, combined with those suggestive images...

"Ah," "This..."

The two women's cheeks flushed slightly, instantly turning a rosy blush.

He lowered his head, not daring to look directly at Jiang Yu, only the sound of his heartbeat was particularly clear in the quiet cave.

Isn't the meaning clear enough that the young master is passing on this technique to them?!

Especially Yuan Yao, who was so well-developed, had her head almost buried in her abundant fruit, making it impossible to see her expression.

Only Yanli, after slightly lowering her head, raised it again, her shyness turning into enthusiasm and initiative, and firmly stated: "Young master, Li'er wants to cultivate this technique."

It's just dual cultivation, isn't it?

Although the posture is a bit unsightly, it's all for improving one's cultivation.

She, Yanli, gave it her all!

"Good, very good, as expected of my obedient and sensible Li'er."

Jiang Yu, who seemed to have been holding back his anger for some unknown reason, suddenly burst into a rage, grabbing the woman in red by the waist, which elicited a soft cry from her.

"Come with me into the house, I'm going to give you some pointers."

The cave dwelling was fully equipped, and Jiang Yu led the little beauty towards the hot spring room.

"Ah!" Yanli exclaimed again, not expecting Jiang Yu to be so eager. She pleaded, "Young Master, I'm only in the Qi Refining stage. Losing my virginity will affect my Foundation Establishment. Can I still practice cultivation techniques...?"

Jiang Yu's gaze was intense, especially as it traced her cherry-like lips, as he coaxed, "Who said I wanted that? Don't worry, you'll see once you're inside."

Then he remembered something and looked at Yuan Yao, who was pretending to be an ostrich: "Yao'er, I'm going in to guide Li'er in her cultivation. You stay at the door and don't move around."

"What?! How can you do that!"

"Young master, you..."

Faced with this unreasonable demand, both women cried out in protest.

"Haha, it's settled then."

Ignoring the two women's protests, Jiang Yu forcefully pulled the beautiful maid in red towards the hot spring room.

…………

The hot spring is bubbling up, with a light mist swirling around it.

"Yanli, come a little closer."

"Closer, yes."

In the hot spring pool, which could accommodate more than ten people, Jiang Yu took off all his clothes, leaned back against the stone wall with a comfortable expression, and half of his body was soaking in the warm water.

His feeling at that moment was absolutely exhilarating!

"Young master~"

The shy maid Yan finally abandoned all worldly possessions and leaned most of her body against the young master's chest.

He closed his eyes slightly, his hands roaming over his alabaster-like skin.

Feeling the smooth texture in his hand, Jiang Yu suddenly said, "Xiao Yan, your cultivation level has reached the Foundation Establishment stage, right?"

Yanli's cheeks flushed, and she said in a hoarse voice, "Yes, young master."

"So, do you want to reach Foundation Establishment quickly?"

As he spoke, Jiang Yu stopped at Liu's waist and suddenly grabbed Man Yue.

Foundation building!

Upon hearing this, Yanli's slightly dazed eyes lit up. She suppressed the strange sensation in her body and looked up at him.

"Young master, may I?"

"Yes, that's fine, as long as Li'er does you a small favor, young master."

"Young master, that won't do..."

"Don't worry, young master is not the kind of person who doesn't know what's important."

Jiang Yu opened his eyes, his gaze fixed intently on her cherry-like lips, and suddenly said, "Li'er, have you ever met someone who can't speak clearly?"

Yanli: !?

Soon, Yanli witnessed it.

As the sound of rushing water rang out, Jiang Yu straightened up, and the angry dragon almost slapped her in the face.

"this..."

Yanli trembled, her ears burning, as if she understood something.

She looked up, about to speak, but saw Jiang Yu's amused yet unquestionable gaze.

She hesitated.

She could only lower her head shyly and serve him with clumsy oral skills.

The hot spring room was filled with rippling blue water, and Yuan Yao, who was guarding the entrance, could hear everything clearly.

At first, she didn't understand.

Unable to resist any longer, he used his divine sense to probe into the hot spring room and witnessed an incredible scene.

Oh my god, how could my senior sister...?

Yuan Yao covered her almond lips, as if a warm current flowed through her entire body, making her feel weak and breathless, and her beautiful eyes filled with a thin mist.

They... went too far.

…………

Time flies, and half a month passes in the blink of an eye.

The day has finally come.

Suddenly, Jiang Yu had a flash of inspiration.

He knew that the time was ripe for a breakthrough, and he immediately went into seclusion to attempt to form the Core Formation.

He had already prepared a backup plan beforehand.

He explained a few things and gave two upgraded high-grade Foundation Establishment Pills, along with some auxiliary pills, to Yuan Yao and Yan Li.

Once he completes his seclusion and forms his core, the two women should be able to reach the Foundation Establishment stage with the help of elixirs.
