High above the firmament, amidst the rosy clouds, Tianxie Ziyin floated in the air like a banished Fairy.

From the gate of ethereal nothingness formed by the ceaselessly swirling thick clouds, countless silver-white lightning bolts cleaved downwards.

Soon, Tianxie Ziyin's graceful figure descended slowly, with the silver-white lightning closely following.

Yang Che's pupils suddenly constricted.

It seemed Tianxie Ziyin was deliberately drawing down this lightning?

No sooner said than done, just as Yang Che pondered, several silver-white lightning bolts had already been guided by Tianxie Ziyin to Jie Tian Peak.

'Boom', 'Crack'.

The silver-white lightning struck precisely on the Bronze Hall Yang Che had just emerged from.

Just as Yang Che was surprised, a miraculous scene unfolded before his eyes.

Huge thunder-fireballs instantly appeared around the Bronze Hall, crackling and exploding.

Soon, the entire Bronze Hall was enveloped by massive lightning, almost as if it were bathing in a river of thunder.

Moreover, Firelight soared into the sky around the Bronze Hall, forming an extremely spectacular and strange scene.

Tianxie Ziyin had also landed on the open space in front of the hall at this time.

"Yang Che, quickly enter the hall. Utilizing this 'Thunder Fire Refining Hall' to Cultivate the Heaven and Earth Chaos Art will yield twice the results with half the effort, allowing you to quickly Cultivate more Ancient God Power."

After Tianxie Ziyin finished speaking, before Yang Che could react, she immediately pulled Yang Che into the Bronze Hall.

As soon as she entered the Bronze Hall, she entered the Void Illusion Magic Stone Space.

Immediately afterwards, Yang Che's mind shook, and countless dense words appeared.

"Devouring Thunder Art?"

Yang Che immediately understood that Tianxie Ziyin had already passed the Devouring Thunder Art to him.

"Yang Che, first Cultivate the Devouring Thunder Art and devour all these lightning bolts into your Dantian for refining."

Tianxie Ziyin's voice rang out.

Yang Che didn't care about anything else, quickly sat down cross-legged, and began to Cultivate the Devouring Thunder Art.

With the previous experience of Cultivating the Sky Thunder Scripture, Yang Che didn't spend much time before he could freely circulate this Devouring Thunder Art within his Physical Body.

As before, the Heaven and Earth Chaos Art and the Devouring Thunder Art could be Cultivated together within his Physical Body.

Thus, under Tianxie Ziyin's guidance, Yang Che, with the aid of the miraculous scene of this 'Thunder Fire Refining Hall', used the Bronze Hall as a 'bridge' to continuously devour lightning into his Physical Body for refining…

This refining process lasted a full half year.

Half a year later, Yang Che ended his devouring and refining of the lightning.

At this time, Yang Che also noticed that the purple Golden Core with the thunder attribute within his Physical Body was more stable, and the golden spots on it became more obvious.

Even more gratifying was that not only had the strength of his Physical Body increased astonishingly after entering Core Formation, but after refining the lightning during this half year, even he was somewhat unclear about the extent of his Physical Body's strength.

Moreover, the Ancient God Power within his Physical Body was even more abundant and surging, making Yang Che overjoyed.

However, Yang Che was very clear that he had a 'Bloodline contract' with Zi Yin, so he unhesitatingly entered the Magic Stone Space, preparing to transfer all the Ancient God Power within his Physical Body to her.

As soon as he entered the Magic Stone Space, a chubby little girl with a jade-carved face ran towards him.

While running, she also randomly threw a spirit fruit from some Spirit Medicine she was holding in her hand into her mouth.

Seeing this little girl, Yang Che affectionately stroked her head, and glanced at the distant, huge ancient flying boat floating in mid-air.

"Yang Che, take this opportunity to form a Soul contract with the artifact spirit of this ancient flying boat."

Tianxie Ziyin walked over from behind the little girl.

Yang Che smiled wryly and said, "If I form a Soul contract, and she recovers her memories in the future, if she has a temperament like yours, wouldn't she dare to directly start a war with me?"

"You're overthinking it. I'm asking you to form an equal Soul contract, not a master-servant contract. This little girl has existed for far longer than I have. If you two were to form a master-servant contract, once her memories recover, with your insect-like Bloodline… I'm afraid it really wouldn't be enough for her to abuse."

Hearing this, Yang Che scratched his nose awkwardly, and then said, "Then let's begin."

Tianxie Ziyin nodded slightly, and then looked at the little girl and said gently, "Xiao Gu, come here to big sister."

Xiao Gu was the name Tianxie Ziyin had given her.

Hearing this, the little girl obediently walked to Tianxie Ziyin's side, without the slightest intention of resisting.

Because she subconsciously knew that the beautiful and indescribable big sister in front of her was sincerely good to her.

"Xiao Gu, big sister is going to extract a strand of your life Soul and give it to that big brother over there, it might… be a little bit painful, are you willing?"

A look of confusion appeared in Xiao Gu's watery eyes.

She didn't know what a 'life Soul' was at all, nor did she know what 'pain' was, but upon hearing that it was for the big brother she relied on and was close to, she immediately nodded without the slightest hesitation.

Seeing Xiao Gu agree, Yang Che also breathed a sigh of relief, and immediately flew out a drop of life Soul essence from between his eyebrows.

Tianxie Ziyin then waved her hand over Xiao Gu's eyebrows.

Xiao Gu suddenly showed a trace of pain, but she glanced at Yang Che and still endured it, only tears uncontrollably flowed from her eyes for some reason.

Tianxie Ziyin fused Yang Che's life Soul essence with Xiao Gu's life Soul.

Then, she divided it into two again, and flew back to Yang Che and Xiao Gu's eyebrows respectively, and quickly integrated and disappeared.

In an instant, Yang Che immediately felt a special connection of mind and spirit with Xiao Gu.

If it was said that previously, he and Xiao Gu could only barely establish contact between their minds and spirits, then at this moment, he felt that this connection of mind and spirit was without any awkwardness or stagnation.

Yang Che looked towards the dilapidated ancient flying boat again, and with a thought, the flying boat actually began to slowly shrink, and could even change direction.

However, very quickly, Yang Che also felt a trace of Xiao Gu's inexplicable sad emotions, so he immediately walked over and gently picked her up.

Seeing this, Xiao Gu smiled through her tears.

Yang Che reached out to wipe away Xiao Gu's tears, and seeing her pure smile, he seemed to be touched at this moment, and inexplicably thought of when his grandfather was still alive when he was a child, he had also sat on his grandfather's shoulders, and he had also had this kind of smile at that time…

Xiao Gu quickly found many spirit fruits from the Tongyou Medicine Garden magically, and then continued to play and frolic with the Winged Fire Dragonfly while eating.

Yang Che withdrew his gaze, suddenly raised his arm and stretched it out in front of Tianxie Ziyin.

Tianxie Ziyin understood immediately, and immediately bit Yang Che's wrist.

Yang Che 'hissed', but still watched Tianxie Ziyin suck his blood in a very 'enjoyable' manner, inexplicably having a faint strange feeling.

After a long time.

Tianxie Ziyin wiped the corner of her mouth, and then carefully looked at Yang Che again, and then said unhurriedly, "You've finally reached Core Formation, it wasn't in vain for me to wait for you for so long."

Yang Che smiled slightly.

Tianxie Ziyin continued, "The Devouring Thunder Art has already been passed to you. I will now pass you the dark attribute Cultivation Technique, Silent Extinction Scripture. These two Cultivation Techniques are enough for you to Cultivate to Nascent Soul Great Perfection."

As she spoke, she gently tapped between Yang Che's eyebrows, and the Cultivation Technique of the Silent Extinction Scripture immediately appeared in Yang Che's mind.

"Take out the Flying Fire Meteor and Jiao Entangling Silk for me, I will help you melt and transform them."

Yang Che took out the Flying Fire Meteor and Jiao Entangling Silk, handed them to Tianxie Ziyin, and then quickly entered the Tongyou Medicine Garden to manage the Spiritual Medicine and Spiritual Plant.

Now, the two acres of ordinary medicine fields have also advanced to Yellow Grade Spirit Earth, and Yang Che has also transformed ten acres of ordinary medicine fields, irrigating them with spirit liquid almost every day, hoping that these ordinary medicine fields will also advance to Spiritual Soil one day.

However, the Profound Rank Spiritual Soil where the Spirit Eye Tree and the nine-leaf dark yang fruit are located has also stagnated in grade due to the lack of spirit liquid and Spirit Fertilizer nourishment.

Moreover, the growth of the Spirit Eye Tree has gradually become the same as before in the past few years. After the Spiritual Soil advanced to Profound Rank, it grew wildly for a period of time, and then it stopped growing much again.

Now, the Spirit Eye Tree is nearly two zhang high, with lush branches and leaves, but Yang Che knows that it is still far from the Spirit Eye Tree that was tens of zhang high as recorded in the Alchemy Notes.

After busying himself in the Tongyou Medicine Garden, Yang Che unexpectedly discovered that many of the Spiritual Medicine seedlings transplanted from the ancient flying boat were actually the main ingredients for refining an ancient Medicinal Pill formula in his hand.

This discovery immediately made Yang Che overjoyed.
