Ye Yu dismissed the electromagnetic rail cannon he had constructed with the Blue Silver Glazed Tree Martial Soul.
Then, transforming into a bolt of lightning, he soared through the sky and landed at the base of the mountain where the Blue Lightning Tyrant Dragon Clan resided.
Blue Silver Glazed Tree—Manifest!
With a thought, Ye Yu summoned his Blue Silver Glazed Tree Martial Soul.
First Spirit Ability: Undying Root!
Second Spirit Ability: Starlight Absorption!
Sixth Spirit Ability: Parasitic Devour!
In an instant, all six of his Spirit Abilities activated simultaneously.
The Blue Silver Glazed Tree exploded from the ground, its trunk expanding rapidly, thick branches extending in every direction, and its canopy growing denser and denser.
In a matter of seconds, it had become a towering titan of a tree.
But the real change was happening underground.
The roots of the Blue Silver Glazed Tree plunged deep into the earth, frantically growing and spreading.
They began to encircle the mountain range where the Blue Lightning Tyrant Dragon Clan was located.
At the base of the mountain, an entire forest of Blue Silver Glazed Trees had grown in the blink of an eye.
With the augmentation of all six Spirit Abilities, the trees drew energy from the earth, absorbing sunlight, nutrients, and life force from surrounding plants.
Not only could this sustain their rapid growth, but it also fed Spirit Power and vitality directly back into Ye Yu.
This meant that summoning his Blue Silver Glazed Tree Martial Soul no longer consumed Spirit Power—in fact, it even replenished it.
Since he had resolved to eradicate the entire Blue Lightning Tyrant Dragon Clan, Ye Yu removed all restraints and allowed the Martial Soul to grow unimpeded.
Very quickly, the trees had spread into the clan's territory.
From underground, the roots erupted through the soil, growing wildly upward and outward, smashing through buildings as they went.
Tree branches, thick as sapphire serpents, whipped and coiled through the air, targeting the disciples hiding inside.
Those caught by the Blue Silver Glazed Trees were helpless. Once entangled, there was no escape—only death.
The disciples who had thought hiding in buildings would protect them from Ye Yu's rail cannon now found themselves being attacked from below.
The trees grew straight through the foundations, crashing into the buildings and commencing indiscriminate slaughter.
They were like grim reapers, reaping life itself.
The disciples were thrown into utter despair.
They were trapped—caught between a rock and a hard place.
They had no choice.
Even if stepping outside meant likely death, dying later was better than dying now.
So the disciples fled the buildings, only to be instantly gunned down by Ye Yu's electromagnetic rail cannon.
Within a few hours, the entire sect lay in ruins, their halls shattered by towering crystal-blue trees.
Not a single disciple survived.
A few Spirit Sages and Spirit Douluo elders of the clan made a desperate last stand.
They all activated Martial Soul Avatar, transforming into mighty Blue Lightning Tyrant Dragons, roaring in fury as they took to the skies and charged toward Ye Yu at the foot of the mountain.
But Ye Yu was nothing if not cautious. He always maintained a safe distance, never letting anyone catch a glimpse of his face or figure.
If he couldn't take them all down in one shot, then he would use his superior speed to retreat and fire again.
One rail cannon shot didn't work?
Then he'd fire two. Or three.
Very soon, all the attacking elders were sniped dead.
Some began to panic when they realized they couldn't even get close to Ye Yu while their comrades were being picked off one by one, heads exploding without warning.
Terrified, a few tried to flee.
But they were far slower than the projectiles fired by Ye Yu's rail cannon, which—at full output from his spirit core—could exceed 2,000 meters per second.
Faster than the speed of sound.
That meant the victims didn't even hear it coming.
Ye Yu didn't know whether among those he killed were Yu Xiaogang's older brother, or his uncle Yu Luomian.
Nor did he care.
In the end, they all became corpses under the fire of his rail cannon.
After eliminating every last visible disciple of the Blue Lightning Tyrant Dragon Clan using the Blue Silver Glazed Tree Martial Soul and electromagnetic cannon, Ye Yu took extra precautions.
He summoned his external Spirit Bone: Thunderous Hell Prison Spear.
Holding the spear in hand, he expanded his Blue Silver Domain to its maximum range and stepped onto the clan's mountaintop.
Using the domain's life force sensing capabilities, Ye Yu scanned the entire sect three times.
He flushed out every remaining disciple hiding in underground chambers and executed them on the spot.
Only after confirming there were no survivors did he enter the clan's treasure vault.
Because his Jade Dragon Bracelet, Wishful Hundred Treasures Purse, and the storage-type Soul Tool in the vault all had capacity limits, he couldn't carry everything out at once.
So Ye Yu used the Soul Tool to load the items and then transferred them via his Blue Silver Space, relocating everything to the mountain housing the Ice and Fire Yin-Yang Well.
After incinerating all the corpses and clearing out the vault...
Ye Yu returned once more to the foot of the mountain.
He activated his Blue Silver Glazed Tree Martial Soul and spent over six hours growing the roots underground.
He completely filled the subterranean spaces beneath the Blue Lightning Tyrant Dragon Clan's mountain with Blue Silver Glazed Tree roots.
Finally, Ye Yu released the summoning of the Martial Soul from the mountain peak and surrounding regions.
RUMBLE—!!
In an instant, the ground beneath the mountain gave way, forming a massive sinkhole.
The terrain collapsed violently.
With thunderous rumbling, the entire mountain peak crumbled in on itself.
The buildings of the Blue Lightning Tyrant Dragon Clan were crushed under the weight of the collapsing rock and buried in the massive crater.
When it was all over, only rubble remained.
All around the mountain, massive cracks webbed across the earth like the aftermath of an earthquake.
"All done."
Clapping his hands with satisfaction, Ye Yu returned to the Ice and Fire Yin-Yang Well via the Blue Silver Space to inspect his spoils.
At the moment, the area was deserted.
Ye Yu had brought Xiao Wu, the transformed 100,000-year-old Soft-Boned Rabbit, back to the Dugu Residence.
Since then, Dugu Bo had remained behind to keep an eye on her.
The well was still under Ye Yu's surveillance—he had planted Blue Silver Glazed Trees here, allowing him to monitor it at any time and teleport instantly when needed.
So it no longer required anyone to guard it personally.
Now, in the quiet of the Ice and Fire Yin-Yang Well, Ye Yu took out the shattered True Dragon Nine Crowns and the Thunder Swap Left Leg Bone from Yu Yuanzhen.
He fused both Spirit Bones into his body.
The process pushed his cultivation to Level 68 Spirit Emperor.
After fusing the True Dragon Nine Crowns, Ye Yu tested its Spirit Bone Skill.
And the results shocked him.
First, it provided a threefold increase to all physical attributes.
This was comparable to the boost of a 100,000-year auxiliary-type Spirit Ability.
That alone would be impressive.
But what stunned Ye Yu most was that it also doubled the power and effectiveness of his Blue Silver Glazed Tree's Spirit Abilities.
That was ridiculously overpowered.
Additionally, it offered a total of 100,000 years of Spirit Ring enhancement, freely allocatable across his six Spirit Rings.
Although no single ring could be boosted beyond 99,999 years, the cumulative enhancement was enormous.
And this was in the True Dragon Nine Crowns' shattered state—with reduced power due to its fragmentation.
Ye Yu could scarcely imagine how powerful it would be if it were ever fully restored.
Author's Note (Clarification):
Some readers seem to have misunderstood the function of the True Dragon Nine Crowns.
It provides a total of 100,000 years of Spirit Ring enhancement, which can be distributed freely.
It's not limited to a single ring.
However, no individual Spirit Ring can be raised beyond 99,999 years.
For example:
If the protagonist's sixth ring is originally a 90,000-year Demon Willow Fluff ring,
He could allocate a few thousand years to boost it to 99,999 years.
The remaining years could then be distributed among his fifth, fourth, third, second, and first rings.
The total enhancement cap remains 100,000 years.
