Boom!

Two months later, a muffled sound emerged from Xia Liu's body.

This was not because his Thunder God Body had broken through.

But rather, his long-dormant cultivation had advanced to the Foundation Establishment Late Stage!

Each Mysterious Thunder within the Thunder Region contained hidden traces of spiritual energy.

This cannot be compared to nature's spiritual energy.

The pure spiritual energy within the thunder is the key to his advancement.

"Hoo..."

Xia Liu took a deep breath.

The vast spiritual energy within his Dantian delighted him.

This feeling, different from the Foundation Establishment Mid-Stage, gave him confidence. Even if faced with a Golden Pill Mid-Stage expert, he could contend!

He could even defeat the opponent!

"Unexpectedly, while the Thunder God Body hasn't made much progress, my Energy Body has advanced first."

"Isn't that obvious? The spiritual energy contained in the Heavenly Thunder is extremely pure. Although there's still a gap compared to the spiritual energy within your body, after nearly half a year of accumulation, it's no surprise you've broken through."

Bai Jue analyzed.

"Indeed, but why hasn't the Thunder God Body reached even the Minor Achievement Realm yet..."

Xia Liu couldn't understand; he had clearly ventured deeper into the Thunder Region compared to before.

The Heavenly Thunder was terrifying, more than double from before.

Yet, the Thunder God Body still hadn't reached Minor Achievement.

This was quite embarrassing.

"Tsk tsk! If the Thunder God Body achieved Minor Achievement so easily, I wouldn't have spent a millennium to cultivate it to perfection..."

...

Xia Liu didn't speak.

A millennium spent cultivating the Thunder God Body to mastery.

Bai Jue was just being opportunistic.

"Cough cough, don't misunderstand, after I broke through to the Nascent Soul Stage, I put the Thunder God Body aside, so it was half-hearted cultivation, and then I easily honed the Thunder God Body to mastery."

"Elder Bai doesn't need to explain, I understand."

"Understand my foot! You think my talent is poor? Back then I..."

Thinking Xia Liu despised him, Bai Jue babbled a string of words.

At any rate, he didn't want Xia Liu to misunderstand.

"Elder Bai, there's a saying that explanations are covering up; too much explanation..."

"Darn it, go play by yourself, I'm going to sleep!"

Bai Jue had nothing more to say; he regretted letting it slip.

Xia Liu would surely laugh to death...

Sigh.

"Hahaha..."

Just as Xia Liu laughed out loud, the sky erupted with thunder.

A ferocious Mysterious Thunder struck him precisely.

"Ah!"

Unprepared, Xia Liu's body forcefully endured it with only the Minor Achievement of his Thunder God Body.

This sudden attack nearly caused him to faint.

"Haha! Dare to mock me, your comeuppance arrived so swiftly!"

This time it was Bai Jue's turn to laugh.

In the Thunder Region, don't act too cocky!

Xia Liu gritted his teeth and endured, assimilating the thunder into his body, then focused intently on cultivating the Thunder God Body.

Ten days later, when a round of thunderstorm descended.

The surface of Xia Liu's body erupted in a dazzling blue light, relying solely on his physical body, without activating the Thunder God Body Heart Technique, he could already harness the Power of Thunderbolt!

"Thunder God Body, Minor Achievement Realm!"

Bai Jue transmitted through divine sense.

"Haha! It finally succeeded!"

Xia Liu couldn't contain his excitement.

At this moment, he felt every part of his body brimming with power.

It was an illusion that he could shatter the void with a single punch.

Cough cough, of course, that was an illusion.

Da da da...

Xia Liu stood in place.

A crisp sound emanated from all over his body.

Having not moved for a long time, stretching his arms gave Xia Liu a long-lost sense of satisfaction.

He pulled open his shirt with a jerk.

He saw strong light flickering on his chest and belly.

Resembling a Glazed Body, quite exquisite.

But soon, Xia Liu realized a problem.

The Minor Achievement of Thunder God Body would cause his body to emit blue light.

If this blue light constantly existed, wouldn't he have to cover himself with a black robe in the future?

The blue light was present on his face and hands.

That's why Xia Liu was concerned.

"Elder Bai, how do I handle this blue light?"

"Don't worry, now that your Thunder God Body just achieved Minor Achievement, the blue light will vanish soon."

"Oh, that's a relief."

Xia Liu nodded and suddenly remembered something, asking, "Does Elder Bai have any methods to gather more of these thunderstorms?"

"What are you planning to do?"

Bai Jue was taken aback.

He sensed Xia Liu had a crazy idea.

"I want to use the spiritual energy within Heavenly Thunder to break through."

"Hmm? You plan to take this chance and break through to the Golden Core?"

"Yes, it's hard to come across such a thunderstorm; leaving now would be a pity. Perhaps trying it might succeed in Core Formation?"

Xia Liu was itching to attempt.

Upon reaching the Golden Core Stage, he might have the qualification to proceed to the Southern Realm!

He foresaw that he would receive great fortune in the Southern Realm.

Perhaps he could even achieve Nascent Soul Formation!

"It might be worth trying."

After a while, Bai Jue responded concisely.

"Please guide me, Elder Bai!"

Xia Liu's mood became thrilled.

This fortune, he wanted to maximize!

"The fourth stage of the Thunder Control Technique's Immortal-Destroying Thunder can gather the Heavenly Thunder within a hundred-mile radius, but are you sure you're ready?"

Even Bai Jue didn't dare to be careless.

Hundreds of miles of Heavenly Thunder. 𝒻𝑟𝘦𝘦𝘸ℯ𝒷𝑛𝘰𝓋ℯ𝘭.𝘤𝘰𝘮

Gathered in one spot, even a Nascent Soul Stage cultivator would have to consider whether they could withstand it.

"I'm ready; even if I fail, Elder Bai can surely protect me."

"Haha, you trust me so much; if I let you get seriously injured, wouldn't that be humiliating? Focus!"

After Xia Liu concentrated, Bai Jue transmitted divine sense, imparting the method of Core Formation and various points of caution to Xia Liu.

"So that's how it is!"

Understanding the particulars of Core Formation, Xia Liu felt enlightened.

Foundation Establishment and Core Formation are two entirely different ranks.

The method of breakthrough is vastly different.

During Foundation Establishment, the cultivator's primordial spirit becomes liquid, able to wield spiritual energy like an ocean.

Golden Core Stage, the primordial spirit elevates, forming a solid golden core state. Once the golden core forms, spiritual energy floods into it.

If the spiritual energy of a Foundation Establishment Cultivator is like oceans.

Then Golden Core Stage would be numerous oceans!

The space in the Dantian is always limited.

But the Golden Core is different; it's like a bottomless pit, capable of accommodating a massive amount of spiritual energy.

Yet, the Golden Core Stage also has limits.

Once it reaches a certain volume, the Golden Core cannot store any more.

One thing must be clear.

The power of the Golden Core Stage far surpasses the Foundation Establishment Stage.

"Once you're ready, go ahead and proceed."

Bai Jue reminded.

"Mm!"

After responding, Xia Liu executed the Seal Decree.

It was indeed the fourth stage of the Thunder Control Technique!

Though he hadn't mastered the fourth step's Immortal-Destroying Thunder yet.

But now in the Thunder Region, merely forming seals could cause Heavenly Thunder to gather.

If Bai Jue performed it, he could effortlessly gather Heavenly Thunder from a hundred miles, even two hundred miles.

He was concerned that Xia Liu might be unable to endure such vast power, which is why he let Xia Liu perform it.

Unable to fully execute the fourth stage of the Thunder Control Technique, Xia Liu could gather only a limited amount of Heavenly Thunder.

This greatly reduced his risk.

"Gather!"

As Xia Liu directed his Seal Technique toward the sky, he shouted.

Within a radius of several dozen miles, thunder roared, and black clouds quickly gathered above Xia Liu's head in the sky.

Due to the Thunder Region's structure being disrupted, thunder no longer descended.

The thunder energy within the gathered black clouds would make even Golden Pill Late Stage cultivators tremble if they were present...
