In the past, the World Tree's growth had primarily devoured the energy of the void. The energy of the entire great domain in which the Star Boundary resided could all serve as nourishment for its growth.
The reason it had grown so slowly before was that the void energy was not particularly dense.
But after a month of fighting, the Heavenly Sword Alliance alone had lost over a hundred Opening Heaven Realm cultivators in battle, and Void Earth had also suffered dozens of casualties. After their deaths, their personal Small Universes collapsed entirely, and their World's Great Power dissipated into the void, drawn by the World Tree's pull and devoured by it.
Receiving such nourishment, the World Tree naturally grew rapidly, and in return, the Star Boundary benefited immensely as well.
That was why the World Tree and the Star Boundary had undergone such tremendous changes.
Yang Kai could only guess as much! Otherwise, the changes before his eyes were simply inexplicable.
Such changes were undoubtedly of unimaginable benefit to the World Tree and the Star Boundary, but with powerful enemies pressing down upon them now, how could Yang Kai have the leisure to consider such matters?
His figure blurred as he shifted sideways to block the Heavenly Sword Palace's path forward. Yang Kai raised his spear and pointed it ahead, his eyes solemn.
They were only a million li from the Star Boundary. If the Heavenly Sword Palace was allowed to advance any further, the Star Boundary would surely fall into enemy hands. They had to stop the Heavenly Sword Palace outside the void no matter what.
Only a fight to the death, without retreat!
Swish, swish, swish…
One figure after another landed beside Yang Kai. As if sensing his determination, the Iron Blood, Red Dust, Beast Martial, Phantom, Flower Shadow, and Ice Feather Great Emperors arrived together in silence.
Right after them, Yue He, Mo Mei, Mao Zhe, Geng Qing, Zhou Ya, Hua Yong, Shu Mudan, Hui Gu, Qing Kui, Su Yingxue, Fang Yue, and Xiang Ying also appeared in flashes.
Twenty Sixth-Order cultivators, lined up abreast, stretched across the void like an impenetrable shield, blocking the space between the Heavenly Sword Palace and the Star Boundary.
Behind the many Sixth-Order cultivators stood dozens of Fifth-Order cultivators!
In flashes of light, with heads bobbing about, over a thousand Opening Heaven cultivators below the Fifth-Order who had been providing support from afar also flew in to help.
The army assembled, their momentum like a rainbow!
"This scene looks familiar!" Iron Blood Great Emperor said with a faint smile.
Beast Martial Great Emperor Mo Huang clenched his fists, producing a series of cracking sounds. "It reminds me of the war between the two races."
Back when they had battled the Great Demon God, many Great Emperors had joined forces to face the enemy. It was the first time they had gathered the Star Boundary's most elite power, aiming to win in a single decisive battle. And though the ones attacking today were the Heavenly Sword Alliance and Zuo Quanhui, how similar the situation was!
If they could join forces to slay the Great Demon God back then, why couldn't they join forces today to destroy the Heavenly Sword Palace and eliminate Zuo Quanhui!
Both were battles of the weak against the strong—enough to awaken boundless heroic passion in one's heart!
"Little Yang, don't you die this time!" Red Dust Great Emperor turned his head to warn Yang Kai.
During that battle against the Great Demon God, Yang Kai had completely died in combat once. Fortunately, the Undying Tree had reconstructed his physical body, bringing him back from death, which gave him the means to continue fighting the Great Demon God.
Yang Kai bared his teeth in a fierce grin. "Don't worry, I won't die!"
He roared: "Kill!"
Instantly activating the Dragon Transformation secret art, his body shot up three hundred zhang. The enormous Azure Dragon Spear raised the blazing sun and crashed toward the Heavenly Sword Palace.
At the same time, over a thousand Opening Heaven cultivators unleashed the power of their divine abilities and artifacts, bombarding the Heavenly Sword Palace head-on.
After nearly a month of fierce battle, even though Zuo Quanhui, a Seventh-Order Opening Heaven cultivator, was personally overseeing it, the Heavenly Sword Palace had still sustained some damage. It was just that this artifact possessed impressive defenses—destroying it completely was still a bit out of reach.
In flashes of light, dense attacks also shot out from within the Heavenly Sword Palace, meeting them head-on.
Countless divine abilities collided in the void and annihilated each other. Rift after rift in the void appeared and then quickly healed.
Most of the attacks were intercepted. A smaller portion struck the Heavenly Sword Palace, causing layer after layer of protective barriers to shatter and flicker out.
Before Void Earth could launch a second attack, the Heavenly Sword Palace suddenly blazed with brilliant light. Ten thousand sword lights flickered out from within it, densely packed, raining down upon the Void Earth forces like a violent storm.
Yang Kai charged to the very front, leading the way. With a thought, an enormous, sky-reaching ancient tree materialized behind him, shielding the void. Its branches hung down, transforming into a barrier that blocked countless sword lights.
Ripple after ripple spread outward, and the Majestic Evergreen secret art also dimmed considerably.
Majestic Evergreen was powered by Wood Element energy, and Yang Kai's Wood Element energy had been refined from the Undying Tree. This technique not only helped heal injuries but also possessed extremely powerful defensive capabilities.
However, Majestic Evergreen was not omnipotent—it could not envelop all the Opening Heaven cultivators. Though it blocked most of the attacks, some still slipped through.
Even though the many Opening Heaven cultivators of Void Earth had been prepared, every single sword light in this round of attacks from the Heavenly Sword Palace was comparable to a strike from a Fifth-Order Opening Heaven cultivator.
Blood sprayed, and dozens fell on the spot.
With a thunderous boom, Yang Kai smashed his spear into the Heavenly Sword Palace, causing its forward momentum to plummet. The entire Heavenly Sword Palace shuddered violently.
Boom, boom, boom…
