The Eight Trigram Soul Seal
"There's not enough time to start gathering 15,000 Soul-Essence. Damn it, actually starting to regret relinquishing those eight thousand souls I had."
As he drowned in his regrets, he perceived several growls coming from all around him, followed by glowing eyeballs which popped up all around him.
He smiled softly, realizing he was already surrounded. "Well, there's no going back now is there. Come forth, my soldiers of the dead."
From the ground, an eerie sound—the groan of earth disturbed—echoed through the silence.
Then, as though answering a cursed summon, several hands began to claw their way out from beneath the soil. First one, then another, until the earth itself seemed to weep, spilling forth its dead.
