"Whoosh!"

Mu Jinyu raised his hand and condensed a Dharma Body in front of him using True Yuan, with the power circulating around to protect him. Its defensive power could roughly reach the Late Stage of the Fanxu Realm.

Then, he let the rune, heavy with murderous aura, shoot like an arrow, directly targeting that True Yuan Dharma Body.

"Boom!" With a sound, the True Yuan Dharma Body was directly shattered by the rune, dispersing into tiny points of True Yuan light.

The rune itself, not long after shattering the True Yuan Dharma Body, also began to flicker unsteadily and ultimately collapsed with a soft poof.

"The power has enhanced considerably…"

Mu Jinyu narrowed his eyes slightly, his gaze sharp as he spoke softly.

Just when the bone arrow was activated, its power could probably kill a mid-stage Fanxu Realm cultivator, but for a Late Stage Fanxu Realm cultivator, it's fairly difficult to kill, at most causing severe injury.

And when the rune was pushed to its limit, the bone arrow that served as its vessel collapsed first. However, the power emitted by the rune increased significantly.

"However, although the bone arrow is ordinary, it served as a vessel to maintain the rune for so many years, which is pretty good."

Mu Jinyu's eyes flashed uncertainly as he recalled the changes in the rune just now and memorized them.

Afterward, Mu Jinyu took out his Dragon Spear and began inscribing the rune onto it.

With the material of the Dragon Spear, inscribing this rune would certainly allow it to be activated to its limit without causing the spear to collapse, maximizing the rune's power.

After spending more than ten minutes.

Mu Jinyu finally finished inscribing the rune on the Dragon Spear.

Thereafter, he once again condensed a Dharma Body using True Yuan, its defensive ability roughly reaching the First Layer Hedao Realm.

Finally, Mu Jinyu solely activated the rune on the Dragon Spear, intentionally suppressing the Artifact Spirit and its inherent power before piercing the True Yuan Dharma Body with one thrust.

"Boom!"

The True Yuan Dharma Body momentarily resisted the sharpness, but soon, as the rune was once again pushed to its limit, the Dragon Spear's edge penetrated the body, causing it to collapse and gradually dissipate.

"Indeed, the difference in vessel enhances the rune's power considerably, though it can at most kill an Early Stage Fusion Realm cultivator."

Mu Jinyu analyzed silently.

Afterward, Mu Jinyu spent time deciphering the bone arrows, stone arrows, and other magical treasures he obtained from Mount Tai, extracting forbidden runes from them.

These runes were not all unique; each arrow had a distinctive rune, yet the majority were the same.

Ultimately, Mu Jinyu only extracted six different runes from these hundreds of arrows.

They were all extremely slaughterous runes.

But they had varying strengths and traits.

The stronger runes were characterized by outstanding sharpness, achieving the ultimate in piercing through with pinpoint accuracy; intensely ruthless with spiral energy attacks, even if they couldn't kill the enemy, they would render them incurable; lastly, wide-range attacks, although their extreme destructive power might be slightly inferior to the others, they were most useful during great battles.

The slightly weaker runes had attributed traits like icy nature or corrosive nature...

Mu Jinyu, after extracting these six runes, inscribed them one by one onto the Dragon Spear.

The Dragon Spear, inscribed with six runes, didn't see a change in material or quality grade, but its power was considerably stronger than before.

"Nice, this journey has yielded tremendous gains."

Mu Jinyu wore a joyful expression, then waved his hand to sweep all the stone dust and bone ash out of the room, taking out those stone booklets with inscriptions.

These stone booklets were what Mu Jinyu obtained from unraveling numerous folded spaces on Mount Tai, found among the remains in those sealed spaces. He only obtained three booklets.

Showing their rarity.

Mu Jinyu was uncertain whether the inscriptions on them were cultivation technique inheritances or the last words of the deceased, but they were rare items he had to bring back.

After glancing at the stone booklets, Mu Jinyu couldn't understand the inscriptions, slightly wrinkling his brow.

Then, he channeled his Divine Sense into them, hoping to sense any remaining spirits within for a general understanding.

Unfortunately, perhaps when these stone booklets were originally inscribed they retained some spiritual imprint, but with the indefinite passage of time, these spiritual imprints no longer even retained remnants.

"What a pity…"

Mu Jinyu sighed regretfully.

In his sighs, he suddenly thought of something, his gaze solidifies, murmuring: "Right, I wonder if Yin Li can understand these."

Speaking, Mu Jinyu spread out his Divine Sense, enveloping the entire Yinlong Mountain, searching for Yin Li's whereabouts.

The other day, after refining the Creation Heavenly Pill using Dragon Marrow, his Divine Dragon Blood, and various spiritual medicines, to improve Gu Xiyan and their aptitude, Yin Li also wished to eat. Ultimately he gave Yin Li one pill, no more. The little one became sulky and ran off.

He guessed she went to eat ice cream, so Mu Jinyu didn't bother with her more. Later, when he departed for Mount Tai, he did not bring Yin Li along.

After scanning with his Divine Sense, Mu Jinyu found Yin Li indulging herself heavily, a subtle smile formed as he stepped forward, vanishing from the room.

"Whoosh!"

Inside a spacious cold storage room.

This place didn't store frozen meat or chicken; it was packed full but only stored one thing.

Ice cream!

"Splash splash…"

Yin Li lay in an ice cream tub, gulping the ice cream with a face full of contentment and eyes filled with satisfaction.

"Little Princess, come help me with something."

Mu Jinyu's figure swayed, appearing in the cold storage, smiling at Yin Li who was devouring ice cream.

"No, I refuse."

Hearing Mu Jinyu's words, Yin Li didn't react with surprise, merely paused her licking of ice cream, then without turning her head, replied before continuing to lick.

Yet, her actions noticeably slowed down compared to before.

Originally showing a tomboy's eating manner, now shifted to that of a lady.

Mu Jinyu said, "Really not going to help?"

"Not helped!" Yin Li replied angrily, adding, "Unless you give me more candies to eat."

What she referred to as candies, of course, weren't actual candies, but the Creation Heavenly Pill.

Mu Jinyu exhibited a wry smile, saying, "Eating those candies doesn't benefit you, while a few of my brothers need them to improve their aptitude, why waste them..."

Pausing, he continued, "How about this, I'll buy a few tons of newly released ice cream for you, how does that sound?"

"Gulp…"

Mu Jinyu heard several sounds of swallowing.

Yin Li backed toward Mu Jinyu, then slowly turned around, her large eyes shimmering, eagerly looking at Mu Jinyu, saying expectantly, "Really?"

"Really." Mu Jinyu nodded.

Thinking, little kids are indeed easy to cheer up.

Yin Li hesitated again, "What flavors are in the new ice cream release?"

Mu Jinyu pondered, replied slowly, "Caramel sea salt, durian mango, vanilla chocolate..."

Actually not certain about the latest ice cream flavors, but he glanced briefly at the cold storage's ice cream flavors and casually named some.

Even if the recent releases aren't those flavors, he could simply adjust the taste as needed.
