Chapter 1511
Two groups of powerful beings faced off in midair, their auras colliding violently. The lingering shockwaves from their previous clash caused the very fabric of space to tremble. At the center of this confrontation, space itself seemed to flicker, like the afterimage one sees in the dark when something flashes repeatedly before their eyes.
As the flickering grew more frequent, a sudden crack of thunder tore through the air. A slender spatial rift appeared, filled with countless threads of lightning.
In an instant, the roar intensified, as if the entire corridor space was crying out in pain. The slender rift expanded rapidly, stretching for over ten kilometers within seconds. It kept growing, faster and faster, and a sense of impending doom began to fill the corridor.
Sensing this aura, both sides abruptly withdrew their power. Without their catalysis, the spatial rift stopped expanding and began to slowly close. The destructive energy roared within the massive rift but could no longer sustain its spread.
After half an hour, the rift finally vanished, and the trembling of space gradually subsided.
On the side of the Northend Allied Forces, the expressions of the strong were grim, but their eyes were cold and resolute. If the Four Knights dared to make a move, they were ready to respond in kind.
The Plague Knight, shrouded in a dark green mist, floated in the sky, glaring coldly at Agalon and his companions.
"I'll let you live a little longer. That damned Blood Lich, before dying, managed to awaken the great Undead King. Our King has already awakened, and will soon come here in person. Your souls will be reserved for our King."
Beyond the Blighted Domain, Deathmist began to rise. The gray fog formed a wall, climbing from the earth to the sky, quickly enclosing everything outside the Blighted Domain. The space beyond the corridor was now sealed off by Deathmist.
The Four Knights slowly retreated into the Deathmist and vanished from sight. The roaring undead followed, disappearing into the Deathmist as well.
The Four Knights did not act because the corridor space could not yet withstand a battle between so many Tier Nine powerhouses. If the space were fully stabilized, the Four Knights would have had no reservations. Their restraint now was mostly due to the awakening of the Undead King.
With all Four Knights present, Lin Yun knew he could no longer disguise himself as an undead. The Death Tome had once been the Plague Knight's scepter, so the Plague Knight would surely sense its aura.
With the undead gone, arranging the Hexagram Formation became much smoother. Within a week, steel fortresses were erected throughout the corridor space, each serving as a crucial node for the formation. Once the space was fully stabilized and able to withstand the power of Tier Nine, the Hexagram Formation could be fully activated.
The segmented activation of the Hexagram Formation now encompassed the entire corridor space, fully protecting it. The undead army could no longer breach the formation.
This massive Hexagram Formation was essentially a colossal cluster of alchemical arrays. Only when combined into a whole could it unleash its true power.
These segmented Hexagram Formations could barely hold back the Four Knights, but stopping the Undead King was even more impossible.
The final battle was about to begin. Space grew increasingly stable, and after more than ten days, it was strong enough for Tier Nine powerhouses to act. However, until complete stabilization, the peak of Tier Nine and those beyond could not fight here.
The Northend Allied Forces had withdrawn from the corridor space, leaving only Lord Agalon, Alonzo, the Three Deans of Astral Academy, and Lin Yun behind. Even the Lionheart King and the Forest Elf King had departed.
Once the space was fully stabilized, they could immediately activate the Hexagram Formation.
The days of waiting were torturous. Even Agalon and Alonzo had no mood for banter, and Lin Yun was pondering how to make use of that Tier Nine ultimate spell slot.
What lay ahead was surely the Undead King, a terrifying being beyond Tier Nine. Offensive spells, even those with eleventh-level power, had little chance of taking down the Undead King in one blow. Defensive spells were even less relevant—after all, there was only one spell slot.
The Undead King's body had already reached near-immortality. Defeating him was far too difficult. Even if everyone here joined forces, it wouldn't be enough. Ten Agalons wouldn't necessarily be a match for the Undead King.
That's why the Lionheart King and the Forest Elf King had left.
Floating in the sky and looking down at the land below, Lin Yun suddenly had an idea. He thought of a Tier Nine spell that seemed well suited to the current situation, but unless the spell could hit the Undead King, it would be useless.
Even with the computational power of the Wheel of Myriad Spells and the Magenergy Array, it was still uncertain if they could track the Undead King's movements, let alone guarantee the spell would hit him.
After pondering for a while, Lin Yun hurried into the alchemy laboratory and began crafting a very special potion. Only a Saint Alchemist could make this potion; without the creative power of a Saint Alchemist, even a Creator might risk their life trying to make it.
All kinds of materials had already been prepared in the materials vault. He had never faced such a difficult situation before, and before advancing to Saint Alchemist, he would never have dared to attempt this potion.
To craft this potion required the alchemist's life force and soul power. Even a Tier Nine Saint Alchemist would suffer for making it, let alone someone weaker.
He took out the materials he had prepared in advance, especially the main catalyst—a drop of Agalon's heart blood, infused with soul power and the essence of life.
