Su Yu once again attempted to summon the Thunderous Yanyu Vine.
With the assistance of Ellex, it was easily summoned.
In the desolate space, lightning flickered, illuminating the entire area.
Su Yu introduced the Thunderous Yanyu Vine to the other two entities present.
Since they would all be living in the Sea of Spirit, getting to know each other was beneficial.
...
Everything was ready, Su Yu signaled the Blue Silver Emperor to start the breakthrough.
Massive Life Force emerged from the Blade of Living Beings, flooding into the Blue Silver Emperor's body through Su Yu and the Emperor's contract.
Actually, Su Yu could transmit it through Space, but using the contract transmission can reinforce the relationship between both parties, and facilitate the upcoming transformation to Soul Spirit.
After all, once the Blue Silver Emperor crosses the tribulation, it would become a Fierce Beast with two hundred thousand years of cultivation.
Su Yu had just absorbed a hundred-thousand-year Thunderous Yanyu Vine, directly absorbing the Blue Silver Emperor would be highly pressuring.
The Blue Silver Emperor must sacrifice as much as possible and fully cooperate, while the Thunderous Yanyu Vine mustn't encounter any mishaps.
...
With the injection of massive Life Force from the Blade of Living Beings, the Blue Silver Emperor's cultivation instantly broke through two hundred thousand years.
For Soul Beasts, the Celestial Tribulation is not a test but a calamity.
Once the cultivation breaks through, it will arrive.
Crossing it would truly make one a Fierce Beast; failing means only death.
Externally, Soul Beasts can only become Fierce Beasts after crossing the tribulation, with a sudden surge in power.
It's not that power surges during the tribulation.
Rather, without this opportunity or fortuitous encounter, one cannot achieve a power surge, thus failing to overcome the calamity.
The Blue Silver Emperor's cultivation broke through two hundred thousand years, the Celestial Tribulation was still far away, and now Su Yu could only continue to make the Blue Silver Emperor enhance.
After breaking through two hundred thousand years, approximately a thousand years more in cultivation was achieved, and high above in the Undead Half-Plane, the Celestial Tribulation began to form.
The terrifying tribulation clouds distributed an oppressive force similar to divine authority.
"Is this the Celestial Tribulation?"
It was the first time Ellex saw a Celestial Tribulation on the Douluo Plane as well.
His illusory energy form furrowed his brows.
"This is a boundary set after rules..."
The Blue Silver Emperor's Celestial Tribulation descended.
Boom! Crack!
A massive lightning bolt fell directly down.
The Blue Silver Emperor's aura was powerful, with tendril-like roots gathering together to form a spear.
"Blue Silver Tyrant Spear!"
The spear scattered the lightning while shattering itself.
This was merely one lightning bolt, though.
Within the clouds nurturing the Celestial Tribulation, terrifying lightning energy brewed.
As the first bolt fell, thousands more lightning bolts closely followed, frenziedly striking down at the Blue Silver Emperor.
Su Yu watched from afar, feeling his heart race.
The intensity of the Celestial Tribulation was no joke.
This two hundred thousand years tribulation might be tough even for a typical Titled Douluo to withstand.
The Thunderous Yanyu Vine began to exert effort as well.
It exercised its racial characteristic, diverting the Celestial Tribulation Power to its front.
It seemed provoked, as the tribulation clouds rolled and rapidly expanded, enveloping both the Blue Silver Emperor and the Thunderous Yanyu Vine.
Inside the Thunderous Yanyu Vine, a dense Life Force transmitted through the contract.
The existence of the contract was quite magical, concealing the rules of the Celestial Tribulation and allowing Su Yu to bolster the two Soul Beasts.
Of course, if they couldn't cross the tribulation, then Su Yu would also be affected through the contract.
However, it wasn't a big problem.
Surviving it and still being able to continue cultivating are two different matters.
As long as there's no immediate death and one survives until the Celestial Tribulation dissipates, then it's considered as having survived.
Lightning bolts crashed one after another.
Even with the intensified tribulation, the Thunderous Yanyu Vine drew most of the tribulation lightning over.
The tribulation lightning was highly destructive, but after adapting to the initial few bolts and refining through the tribulation lightning, compressing the Thunder Tribulation power within, the absorption by the Thunderous Yanyu Vine was smoother.
The Celestial Tribulation isn't a test for Fierce Beasts, it's a calamity.
Yet for the Thunderous Yanyu Vine, it was an outright tempering.
As long as it was tempered by lightning, the Thunderous Yanyu Vine's cultivation could be enhanced.
Leveraging Su Yu's Ultimate Life support, the Thunderous Yanyu Vine aggressively swallowed the tribulation lightning.
The Blue Silver Emperor felt the pressure reduce considerably.
Originally thought that bringing another in would make the tribulation harder to cross, but it seemed it had little impact.
The addition of the Thunderous Yanyu Vine seemed merely to borrow a lead from here, with another part for itself set aside to pass.
...
The Celestial Tribulation of the two hundred thousand years Fierce Beast lasted quite long.
It struck continuously for three days and nights without any sign of stopping.
Su Yu also directly felt the fearsome nature of the Celestial Tribulation.
He fully mobilized the Life Force from the Blade of Living Beings, not even converting it into Ultimate Life Attribute after Martial Soul absorption, and directly injected it into the Thunderous Yanyu Vine, keeping it alive.
"Are you still holding on this hard?"
After absorbing the Fierce Beast's Celestial Tribulation for three days and nights, the Thunderous Yanyu Vine had reached the edge of ten thousand years of cultivation.
Stimulated by Su Yu, the Thunderous Yanyu Vine crackled all over, disregarding its already somewhat burst body, forcibly swallowing all surrounding Celestial Tribulation lightning.
Even the Blue Silver Emperor's side lightning emptied instantly.
Taking this opportunity, the Blue Silver Emperor swiftly absorbed and digested the Power of Life transferred over by Su Yu and simultaneously requested for Su Yu's Extreme Attribute boost.
Boom!
Within the Thunderous Yanyu Vine's main body, thunder roared louder than the lightning rolling in the tribulation clouds above.
Cracks appeared all over its main body.
Lightning exploded.
Just about to detonate.
An ultimate burst of Life Attribute emerged.
Su Yu's Ultimate Life Attribute slightly merged into the Thunderous Yanyu Vine at this critical moment through the contract.
