Starting From A Son In Law To Build An Long Lasting Family Chapter 1793: 456: Enemy from Liang Country, True Spirit Tribulation! (3)

A brief survey revealed the truth.

The Void Kun’s physical form had clearly become far more shriveled and lackluster than it was previously.

It was highly likely that upon completing the cultivation of the "Brahman Demon True Saint Technique," nothing but a hollow husk would remain.

"Refining this without utilizing the Demon Core would be quite a challenge."

A demon beast’s most vital essence is concentrated within its Demon Core!

Lu Changsheng intended to employ the Void Kun’s Demon Core to forge a Spirit Treasure Embryo, which would simultaneously replenish his Void Spirit Body Origin and advance his Cultivation.

Consequently, this particular Void Kun—despite having just ascended to the Fourth Rank—seemed insufficient for his requirements.

He performed a Cleansing Technique before stepping into the main hall.

"My lord."

"Father!"

Ling Zixiao, Lu Lingxiao, and Lu Wangshu were all present, waiting for him.

"Very well, I shall handle this personally," Lu Changsheng stated plainly.

He then used his Divine Sense to reach out to the Sea Splitting Mysterious Whale, questioning it about the impending True Spirit Tribulation and its level of certainty.

The Sea Splitting Mysterious Whale sent back an immediate response, expressing total confidence in surviving the trial.

Its bloodline had reached a tipping point; the Fourth Rank Stone Dragon Heart, the Double-headed Flood Dragon Demon Core, and the Eight-Clawed Devil Fish it had consumed were still being processed. The True Spirit Tribulation would serve as the perfect catalyst to fully refine these energies.

However, a proper setting was required for the breakthrough.

For the whale, the Sea Eye located within the Great Dream Marsh was the most ideal location currently available.

The only concern was the potential presence of other demon beasts at the Sea Eye. While usually not a threat, any interference from sea beasts during the critical moments of the tribulation would be disastrous.

Thus, in addition to giving its report, it requested that Lu Changsheng act as its Protector during the process.

"Since you are certain of success, let us depart."

Lu Changsheng nodded his approval after hearing the whale's reasoning.

While summoning the Golden-Winged Heavenly Peng, he paused for a moment of reflection. He decided to extract three gourds of Essence Blood from the Void Kun, intending for the Sea Splitting Mysterious Whale to use them as a potent tonic later on.

"Are you absolutely positive there will be no issues with the tribulation?"

Lu Changsheng sought confirmation one last time.

If the creature harbored any doubts about the danger, he was prepared to spend time gathering Heaven and Earth Spiritual Materials to craft Healing Pills or a couple of Magical Treasures to aid the crossing.

After all, he had invested an immense amount of toil and resources to bring the beast to the verge of a True Spirit bloodline evolution.

If it were to perish under the Heavenly Tribulation now, Lu Changsheng would likely cough up blood from pure frustration.

"Master, have no fear!"

The Sea Splitting Mysterious Whale radiated self-assurance, explaining that its breakthrough was a natural progression rather than a forced limit-break achieved by sacrificing its life force.

"Understood."

With that assurance, Lu Changsheng gave a final nod.

Before they set out, however, Lu Changsheng joined his son Lu Lingxiao and daughter Lu Wangshu in stripping the Sea Splitting Mysterious Whale's body of all the treasures it had collected.

Utilizing his Tianyuan Lotus, the Formless Treasure Wheel, and the Qiankun Shadow-Confining Belt, the task of transporting these Heavenly and Earthly Treasures was made effortless.

"Incredible..."

Lu Changsheng couldn't help but sigh as he surveyed the massive pile of demon cores, various demon beast remains, spiritual herbs, and crystal ores.

Though the majority were only First Grade or Second Rank—with a mere handful reaching the Third Rank—the sheer volume made the collection formidable.

By Lu Changsheng’s mental tally, the market value of these diverse materials and corpses likely reached several million Spirit Stones.

Given the Lu Family's current standing, there was no longer a requirement to sell such items on the open market.

Rare demon cores could be repurposed for Foundation Establishment Elixirs.

The carcasses of the demon beasts would provide raw materials for Artifact Refining, Talisman-Making, and the construction of puppets.

The Lu Family’s puppet production was no longer restricted to his personal blueprints.

They now possessed the capability to design new models based on available materials, such as specific demon beast skeletons.

Nonetheless, these custom puppets required significant manual labor and time, lacking the efficiency of a standardized assembly line.

"Zi Xiao, I need you to organize and clean these items later. Big Black and I are leaving now," Lu Changsheng instructed Ling Zixiao once the haul had been moved to a large hall within the City Lord Mansion.

"I will see to it," Ling Zixiao answered.

"Father, what is a True Spirit Tribulation actually like? May I come along to witness it and broaden my horizons?"

Lu Wangshu asked as her father and Big Black prepared to travel to the Sea Eye for the breakthrough.

Most common practitioners were only familiar with the Transformation Heavenly Tribulation of beasts or the Nascent Soul Heavenly Tribulation of human cultivators.

"The Sea Eye is situated in the depths of the Great Dream Marsh, a place where both Divine Sense and mana are suppressed. You have seen it yourself," Lu Changsheng explained to his daughter. "The primary threat of the True Spirit Tribulation isn't just the lightning itself, but the fact that Big Black's bloodline evolution might attract other Demon Kings. It could become quite perilous."

This wasn't a fabrication; it was based on his own deductions and what Big Black had shared regarding the nature of the Heavenly Tribulation.

As Hong Lian had once mentioned, a successful breakthrough from Core Formation to Nascent Soul required perfect timing, a favorable location, and internal harmony—alongside a touch of fate.

Success could be compromised if the setting was hostile or the timing poor—such as when rivals or enemies strike during the moment of vulnerability.

The Supreme Elder of the Yiming Ghost Sect was a prime example.

That individual had spent decades preparing after signaling his intent to reach the Nascent Soul realm. He eventually had to rely on the political weight of Liang Country and the power of the [Myriad Ghosts Blood Pool] to fend off the Heavenly Sword Sect during his ascension.

Then there was Absolute Sword True Monarch.

His cultivation was sufficient for a breakthrough much earlier than he attempted it.

Yet, for the sake of security, he waited for the Tianyuan Secret Realm to open so he could achieve his breakthrough in total secrecy.

Among demon beasts, the law of the jungle was even more brutal, with fierce internal competition.

Since the Sea Splitting Mysterious Whale believed the tribulation itself was manageable, Lu Changsheng naturally focused his concerns on external interference.

"I understand," Lu Wangshu replied.

Realizing the gravity of the situation, she immediately wished her father a safe journey and Big Black a successful tribulation.

"After Big Black reaches the Fourth Rank, I will take you on that trip I promised."

Lu Changsheng had previously told his daughter she could ride the Sea Splitting Mysterious Whale for a tour, but the whale had spent the last few years in a deep sleep, processing the Double-headed Flood Dragon Demon Core.

Because of this, the promised outing had been delayed indefinitely.

"Thank you, Father!"

Lu Wangshu smiled. Though her father had kept her waiting for years, she understood the reasons behind the delay.

...

For this journey, Lu Changsheng did not go unprepared. He packed various Formation materials and brought the [Sun and Moon Taiji Mysterious Light Mirror].

When facing a tribulation, it was best to be ready for any possible complication.

Six weeks later, Lu Changsheng arrived at the Sea Eye of the Great Dream Marsh atop the Sea Splitting Mysterious Whale.

A Demon King at the Late Stage of the Third Rank currently occupied the Sea Eye.

"Truly, I have no desire for unnecessary slaughter," Lu Changsheng lamented with a sigh.

However, he couldn't simply chase it away; if it returned later with reinforcements during the breakthrough, it would be a disaster. He had to be thorough. Lu Changsheng drew the Great Luo Sword Embryo and began the grim work.

Sometime later.

"So destitute!"

Lu Changsheng remarked, shaking his head as he looked over the meager crystal deposits in the Demon King's lair.

On reflection, it made sense. These Demon Kings usually originated from the Starry Sky Sea.

They were likely outcasts or losers of power struggles who fled here, meaning they had little wealth to their names.

Lu Changsheng then began constructing a Formation at the Sea Eye.

It wasn't a complex Taboo Formation, but a Third Rank Great Formation designed to mask their Qi Mechanism, gather spiritual energy, provide defense, and assist in healing.

Despite being a Top-Level Third Rank Formation Master, setting up a Taboo Formation was a massive undertaking that one person could not finish quickly.

He recalled the Second Rank Great Formation at Bi Lake Mountain, which required a large team and over a year to complete.

After a month of labor, Lu Changsheng finished the Third Rank layout. He then settled in to wait for the Sea Splitting Mysterious Whale's True Spirit Tribulation to begin.
