On this trip to the Tiangan Secret Realm, Mu Jinyu's greatest gain was monopolizing the Creation Divine Liquid in the Life and Death Creation Pool, allowing the seed of the Mystical Little Tree to finally take root and sprout again, turning back into a sapling.

Secondly, he acquired many Space Law Fragments and Life and Death Law Fragments.

When Mu Jinyu first entered the Tiangan Secret Realm, he thought these law fragments could only be digested on the spot. However, he later discovered that they could be stored in his body without refining.

Thus, Mu Jinyu gathered additional law fragments to bring back for Chu Huannian. This would allow her to accelerate her training in the Unity Realm Stage, striving to quickly advance to the Void Breaking Realm and potentially become an intermediate student!

These gains are the usual opportunities for anyone entering the Tiangan Secret Realm.

As for other gains, they naturally involved killing those imperial family descendants and looting their Qiankun Rings, acquiring treasures from them.

Many ordinary imperial family descendants didn't bring valuable items, as they clearly anticipated the possibility of dying in the Tiangan Secret Realm.

Therefore, they didn't bring valuable items inside.

The one Mu Jinyu killed, Ji Changfei, was the young core member of the Ji Clan, and his brother was also there, so each brought a replica of the clan's treasured Yin-Yang Qiankun Sword.

The sturdy Ji Changfei carried the Yang Kun Sword as his replica.

At the time, outside Duanchang Gorge, Ji Changkong repeatedly wielded his Yinqian Sword, attempting to resonate with the Yang Kun Sword, aiming to depart with the dual swords combined.

But under the suppression of the Earth Emperor's Tome, it failed to stir up any turmoil.

Mu Jinyu had no idea this sword had such a significant background, being a replica of the Ji Clan's treasured sword.

Even as a replica, its rank was not low and should be at the Creation Divine Weapon level!

Higher than the Life and Death Divine Weapon by one rank!

Mu Jinyu didn't even own a Life and Death Divine Weapon.

If Ji Changfei had used the Yang Kun Sword during their fight, he might not have been killed instantly.

Perhaps he could have endured a few more moves!

After killing Ji Changfei, Mu Jinyu obtained his Qiankun Ring and, upon inspection, discovered the Yang Kun Sword within, noting its excellent material, but found it hard to refine.

He speculated that a special restriction had been placed during its refinement, preventing non-Ji Clan members or those without the right incantation from using the flying sword.

Noting its excellent material, being a Creation Divine Weapon, he decided to keep it and immersed it in the River of Oblivion to see if it could wash away the Ji Clan's branding, enabling his use.

At worst, he could reforge it into a new Magic Treasure!

This action rendered Ji Changkong's attempt to use the Yinqian Sword to draw out the Yang Kun Sword to find the culprit ineffective.

If Mu Jinyu's murder of Ji Changfei had been exposed, even Wei Qiankun's formidable presence might not have quelled the Ji Clan's wrath so easily!

With the matter still undiscovered, he had more time to cultivate and strengthen himself.

Mu Jinyu slowly focused his divine sense into the Earth Emperor's Tome.

"Clang!"

With a thought, the Three Life Stone slowly shifted aside!

Instantly, a golden flying sword leaped out, radiating dazzling brilliance like a blazing sun, unmatched in sharpness.

If not within the Earth Emperor's Tome's Minor World, the void would likely have collapsed in a vast area.

This was the Ji Clan's Yin-Yang Qiankun Sword replica.

However, without the master's control, it stood dumbly in the void after leaping from the ground, undertaking no other actions.

The previous leap was a residual command from the Yinqian Sword's previous call.

Now, with the Yinqian Sword too distant, it couldn't feel the call to resonate, nor take any further action.

"Indeed a fine sword, but the Ji Clan's branding is too deep. Even the River of Oblivion can't cleanse it entirely. The unique design also makes it awkward to use. Better wait for an opportunity to reforge you!"

Mu Jinyu glanced at the Yang Kun Sword, shaking his head in some regret.

This sword far surpassed the ordinary low-grade divine flying sword he had purchased for a dozen academic credits at Dongyue Mansion's Treasure Pavilion.

The gap was akin to comparing a bamboo sword made by mortals to a Spiritual Treasure!

The difference was even greater.

Unable to refine and use it, what a pity!

"Whoosh!"

Mu Jinyu then threw the Yang Kun Sword back into the River of Oblivion, using the Three Life Stone to suppress it, intending to let it soak longer.

His cultivation was still relatively low; even if he wanted to smelt the Yang Kun Sword into iron to reforge a Magical Treasure, he lacked the power.

So he decided to ignore it for now.

Retracting his gaze, Mu Jinyu then searched through the jade slips found in Ji Changfei's Qiankun Ring.

These jade slips recorded the Ji Clan's core cultivation methods.

This was why the clan elders insisted on finding the murderer after Ji Changfei's death, unlike other imperial clans.

Ji Changfei had carried their clan's core cultivation methods, which would have significant consequences if leaked!

After the Life and Death Creation Pool, Mu Jinyu had spent considerable time examining these jade slips from afar.

Although this Cultivation Method involved Foreign Race Bloodline,

certain aspects were enlightening for Mu Jinyu, holding considerable reference value.

It described integrating Divine Soul Power with Physical Strength to achieve resonance in the Five Viscera and Six Bowels, accelerating blood replacement and marrow cleansing.

The Ji Clan did this to better accumulate their Strong Clan Bloodline and maintain its purity.

They aimed to expel any weak Foreign Race Bloodline within themselves as much as possible.

The Ji Clan contained not only Divine Race bloodline but also Devil, Demon, and Immortal Clan bloodlines.

Like Ji Changfei, whose Demon Race bloodline was potent, it didn't mean he lacked Divine, Devil, or other Foreign Race Bloodline.

The cultivation of this method aimed to purify his Demon Race bloodline, retaining as much useful Human Race bloodline as possible while expelling useless Divine and Devil bloodlines!

To make oneself as purely inclined towards the Demon Race as possible.

Thus, their Foreign Bloodline Cultivation Path could extend further.

Mu Jinyu found this method interesting, worthy of reference to perfect the "Marrow Nourishment Chapter." It might mean less need for constant consumption to recuperate after each breakthrough, like a reborn Starving Ghost.

As Mu Jinyu studied the Cultivation Method, he contemplated how it could supplement the "Marrow Nourishment Chapter."

Time passed unconsciously.

Night fell soon.

Mu Jinyu shook his head, pausing his research to venture outside.

Chu Huannian had just returned.

Mu Jinyu found her and explained that during the trip, over thirty intermediate students had died, including many ranked in the top thirty, hence Dongyue Mansion would soon promote a new batch of intermediate students.

He encouraged her to strive harder.

"But my cultivation is still lacking, is that alright?" Chu Huannian felt somewhat troubled, hearing this.
