In the original story, A Yin only reached the mature level of 60 after nine years, and then gave birth to Tang San.
Currently, A Yin is at most at level forty-something.
Without maturity, she couldn't get pregnant. That wouldn't do — she had to quickly reach level 60 and mature.
The first thing Ye Yu thought of was the Ice and Fire Yin Yang Well.
That place was practically a paradise for plant cultivation.
Just like in the original, A Yin, by staying near the Ice and Fire Yin Yang Well, managed to regain human form in just five years.
But even so, that still wasn't enough.
Ye Yu only had three months. Three months — unless they started dual cultivation in the Ice and Fire Well from the get-go,
it would be impossible for A Yin to reach maturity in that time.
So, Ye Yu decided to first teach her the Universe Origin Energy cultivation method — starting with the "Five Hearts Toward the Heavens" technique to get her accustomed.
After that, he took A Yin straight to the city.
In the skies!
A white streak split through the sky like a sword, seemingly dividing the heavens in two.
Soon, the two arrived in the city, found a large hotel, and checked into a suite.
Inside the hotel room!
A Yin looked at Ye Yu with unease, a pleading look in her eyes.
Although she did have feelings for him, everything was happening too fast — they had only known each other for less than a day.
"What are you thinking about? I said I'm going to teach you a technique..."
Seeing her nervousness, Ye Yu laughed and flicked her forehead lightly.
"Ah!" A Yin yelped and quickly covered her forehead, looking at Ye Yu pitifully.
"Come on, sit cross-legged."
Ye Yu began to guide A Yin in the "Five Hearts Toward the Heavens" method to absorb Universe Origin Energy.
Realizing she had misunderstood Ye Yu, A Yin blushed and sighed in relief.
She had just been thinking about how to reject him, but now it was clear he really just wanted to teach her.
Though a bit confused, A Yin listened attentively and followed Ye Yu's guidance.
Time slowly passed...
Ten minutes...
Half an hour...
An hour...
A Yin still couldn't sense the Universe Origin Energy Ye Yu spoke of. Just as she thought she'd failed —
Threads of Universe Origin Energy began to gather from the void and flow into her.
Seeing this, a smile formed on Ye Yu's face.
One hour to succeed — it seemed A Yin was indeed a genius.
After all, back then, it took him nearly a month due to his own body's limitations.
At that moment, A Yin sat cross-legged, eyes closed, "five hearts toward the heavens,"
feeling those threads of energy pouring into her body — a comforting, warm sensation.
The energy made her feel like her soul was about to ascend.
This energy was different from soul power obtained through meditation — its quality was far higher.
How much higher? She couldn't say for sure, but at least ten times greater.
Moreover, this energy was fundamentally transforming her body, strengthening it.
And most importantly — it was enhancing her bloodline.
She already had the Blue Silver Emperor bloodline, and yet, it was still improving.
The shock nearly made her lose focus.
"Don't overthink! The first cultivation session is critical — don't let your mind wander," Ye Yu said.
A Yin quickly stabilized her mind and resumed absorbing the energy with all her might.
Her whole body craved it.
Every single cell was cheering, like a traveler in the desert finally finding water.
Each cell devoured the energy greedily, growing stronger.
Outside, Ye Yu nodded in satisfaction, watching her go all out.
Buzz! Buzz!
A buzzing sound emerged, and four spirit rings appeared around A Yin — yellow, yellow, purple, purple.
"So these are spirit rings?"
Ye Yu looked at them curiously, itching to study them, but held back.
He'd have time later.
Time passed.
As A Yin absorbed more Universe Origin Energy, her spirit rings began to change.
The original yellow-yellow-purple-purple rings became purple-purple-purple-purple.
This surprised Ye Yu.
And their color continued deepening, with signs of turning into black ten-thousand-year spirit rings.
Soon, night fell, and A Yin still hadn't awakened.
Buzz!
Just then, a fifth spirit ring appeared — a pitch-black ten-thousand-year ring encircled the previous four.
"She broke through to level 50 already?"
Ye Yu was astonished. He had underestimated the power of Universe Origin Energy — and A Yin's talent.
Even after reaching level 50, A Yin remained in meditation, continuing to absorb energy.
She cultivated all through the night.
By midnight, her third and fourth rings turned black.
By morning, the first and second followed suit.
Finally, A Yin opened her eyes.
Feeling the strength coursing through her body, she was overwhelmed with joy.
Especially when she saw the five black spirit rings circling her — her red lips parted in awe and didn't close for a long time.
Ten thousand years... twenty thousand... thirty thousand... forty... fifty thousand...
Nourished by the Universe Origin Energy, A Yin had undergone a complete transformation — she looked even more beautiful,
with a divine, untouchable aura.
"Brother Yu, what is this?"
A Yin looked at Ye Yu joyfully and jumped into his arms.
"This is a different kind of cultivation. You weren't absorbing soul power, but Universe Origin Energy.
What you just used is the Five Hearts Toward the Heavens method..."
Ye Yu explained Universe Origin Energy to her in detail.
After he finished, Ye Yu was struck by realization —
just a single Five Hearts Toward the Heavens session had boosted A Yin by over ten levels.
That was absurd.
He had clearly underestimated the difference between Universe Origin Energy and soul power.
If he also taught her the Guiding Technique, she might reach level 60 in no time.
Upon hearing his explanation, A Yin quickly understood the difference between this and the soul power meditation used on the Douluo Continent.
She was amazed that such a method even existed — and shocked at how powerful the Universe Origin Energy truly was.
It didn't just enhance her strength, speed, and body — it boosted her spirit ring years,
and most crucially, elevated her bloodline.
Compared to this, soul power cultivation was like heaven and earth.
