Su Xiao and Caesar's plan had succeeded, but not completely. The first kill of Beast Morachi yielded 8.6% of the World Source, but the second kill had reduced that to 7.9%.
At first, Beast Morachi could revive once every five hours. After Su Xiao and Caesar increased the energy output of the spell formation, this time had been shortened to once every two hours. That was already the limit. Any further increase in energy output might cause the "Dark Spell Formation" to explode.
It was two in the morning, and more than fifty hours remained before the next dark tide appeared.
Because Su Xiao had used Extreme Blade Moon here repeatedly, the originally black-sand battlefield had been compressed into a relatively flat area with hardness surpassing steel, making the "Dark Spell Formation" resting on it more stable.
Above the dark formation was a hollow hexagonal crystal over ten meters in diameter. Su Xiao had constructed it by converting 2.7 million points of Mana into Aria Crystals. Its inherent strength was already astonishing, and dozens of layers of Sealing Technique covered its surface.
The hexagonal crystal happened to envelop a black dot in midair at its center. After Beast Morachi's "revival point" had refreshed twice, it had stabilized there. It was not that Beast Morachi could not choose its own revival location; rather, the "Dark Spell Formation" forcibly dragged it here to revive.
Inside the hexagonal crystal were more than a dozen "Beast Cores." At this moment, they were ricocheting through the crystal at extreme speed, occasionally leaving black marks in space, demonstrating their power.
Thus, whenever Beast Morachi revived, it would immediately be blasted full of holes by the "Beast Cores" before it could react, then return to the Abyss to revive again. This was practically an entirely automated way
