A brilliant silver-blue light burst forth from Ah Yin's body, rapidly spreading in all directions.
At that moment, Ye Yu swiftly stored Tang Hao back into his storage-type soul tool, the Wishful Hundred Treasure Purse.
After initiating the sacrifice, within the silver-blue light barrier it created, flames tinged with blood-red ignited across Ah Yin's body. Her voluptuous and elegant figure gradually crystallized into a blood-colored crystal statue, suspended in midair.
From the crimson crystal statue that Ah Yin had become, streams of red light carrying soul power and life force continuously flowed out, pouring directly into Ye Yu's body.
Ye Yu could clearly feel the surging vitality nourishing and strengthening every fiber of his being. At the same time, the soul power transferred through the sacrifice was steadily increasing his internal reserves.
However, since his current cultivation had already reached rank 70, the soul power from the sacrifice couldn't be fully absorbed until he acquired his seventh spirit ring to break through the bottleneck.
Before long, Ah Yin had completely sacrificed all her life force and soul power, leaving behind only:
a single blood-red 100,000-year spirit ring,
a transparent left leg spirit bone, resembling blue crystal and flickering with silver-blue starlight,
a Blue Silver Crystal Seed,
and an External Spirit Bone: Demon Willow Fluff.
The 100,000-year spirit ring immediately flew toward Ye Yu, wrapping itself around his summoned Blue Silver Jade Tree Martial Soul.
The Blue Silver Emperor Left Leg Bone, the Blue Silver Crystal Seed, and the Demon Willow Fluff external spirit bone all dropped gently into Ye Yu's arms.
Because the spirit ring had come from Ah Yin's voluntary sacrifice, it didn't require any further refining. The ring instantly fused with Ye Yu's Blue Silver Jade Tree Martial Soul, becoming its seventh spirit ring.
Upon absorbing the 100,000-year spirit ring from the Blue Silver Emperor, the Blue Silver Jade Tree Martial Soul didn't undergo any drastic transformation. Only the golden veins running through the trunk became even more defined, golden patterns emerged along the bark, and the internal vitality intensified dramatically.
But beyond that, Ye Yu sensed something new—a unique ability had awakened.
It wasn't a spirit ability, but rather, a form of authority.
Without even needing to operate the Inner Core Technique or channel his spiritual power, Ye Yu could now sense the emotions and thoughts—the joys and sorrows—of nearby Blue Silver Grass. Through the Blue Silver Jade Tree Martial Soul, he could influence them directly, enhancing their growth speed and cultivation efficiency, subtly guiding them to evolve toward the lifeform of his own Martial Soul.
Even more astonishing—he could now borrow their soul power and life force.
This revelation left Ye Yu practically trembling with excitement.
This was no ordinary effect—it was clearly the authority of the Blue Silver Emperor!
Yet compared to the traditional Blue Silver Emperor, Ye Yu's Blue Silver Jade Tree Martial Soul wielded an even more advanced authority. After all, normal Blue Silver Emperor authority only allowed communication and influence—but Ye Yu's version enabled him to actively guide Blue Silver Grass to evolve, turning them into closer replicas of his own Martial Soul.
He immediately realized the potential: if, one day, he could fully materialize his Blue Silver Jade Tree Martial Soul and endow it with complete sentience, then as long as he planted its offspring all over the Douluo Continent, he could use this authority to awaken the spiritual nature of the entire world's Blue Silver Grass.
Each one of those would become a potential follower.
After pondering it for a moment, Ye Yu gave this power a name:
Blue Silver Decree.
With the seventh spirit ring now in hand, Ye Yu was eager to experience his new seventh spirit ability:
Martial Soul True Body.
On the Douluo Continent, the seventh spirit ability—Martial Soul True Body—was universally acknowledged as one of the greatest power spikes for a soul master, rivaling even the might of 100,000-year soul skills.
"Seventh Spirit Ability: Blue Silver Jade Tree True Body!"
With a surge of lightning, Ye Yu soared into the air and landed in a forest clearing outside the mountain range where the Ice and Fire Yin Yang Well was located. Brimming with anticipation, he activated his seventh spirit ability.
In an instant, as the seventh ring lit up beneath him, the normally one-meter-thick Blue Silver Jade Tree exploded with radiant blue-silver light.
Its trunk swelled rapidly. In a matter of seconds, it expanded to over ten meters in diameter and over three hundred meters tall.
Its thick branches unfurled like a canopy in the sky. From those azure crystal-like branches and leaves, tiny starlight specks, crescent moons, and golden sun-like orbs shimmered like a tapestry of the cosmos itself.
Under the state of Blue Silver Jade Tree True Body, the Martial Soul's size and strength reached staggering levels. Its life force and regeneration rate increased fourfold.
Even more absurd—within a one-hour time window, all spirit abilities from the Blue Silver Jade Tree could be used without cooldown, their effects and power tripled, and energy consumption halved.
"As expected… Martial Soul True Body really is the most powerful spirit ability available to soul masters."
"Even a ten-thousand-year version is on par with a 100,000-year spirit skill."
"And the stronger the Martial Soul's quality, the more terrifying the enhancement!"
"With the innate quality of my Blue Silver Jade Tree and the boost from a 100,000-year Blue Silver Emperor spirit ring, the seventh ability it grants me is nothing short of monstrous!"
Bathed in this surge of power, Ye Yu couldn't help but laugh in satisfaction.
Then, staring at his now-massive Blue Silver Jade Tree, he activated all six previous spirit abilities in rapid succession.
Empowered by their combined effects, the Blue Silver Jade Tree expanded again—its crystalline trunk now over fifty meters wide, and its towering height surpassed a thousand meters.
Its branches were now so massive that horse-drawn carriages could travel along them.
"Now this... this is what it means to reach the level of a Great Pillar."
Once the effect of the seventh spirit ability ended, Ye Yu transformed back into a bolt of lightning and returned to the Ice and Fire Yin Yang Well.
He pulled out a single blue crystal seed, and a knowing smile appeared on his face.
"Just as I expected… Blue Silver Emperor, being of the ultimate life attribute, is not so easily killed."
"After regaining 100,000-year cultivation and performing a second sacrifice, she still managed to leave behind a seed."
"That works out even better."
Looking at the seed in his palm, Ye Yu prepared to replant it in the Blue Silver Domain.
Once Ah Yin regrew into a sapling, he would once again use the Demon Willow Fluff to raise her cultivation to the 100,000-year level and let her reform into human shape.
However, this time, he wouldn't take another 100,000-year spirit ring or soul bone from her.
Instead, he planned to use Demon Willow Fluff to directly extract the Blue Silver Emperor bloodline from her.
Compared to siphoning Tang San's Blue Silver Emperor bloodline, this method would be far more efficient.
With Ah Yin willingly cooperating, Ye Yu could finally perfect the integration of the Blue Silver Emperor bloodline into his own body—and maybe even unravel the mystery of self-generated spirit rings in the process.
