“Omega Blade, kill Gorouzaburou.”

The moment he finished speaking, the Sage collapsed. It was almost unsatisfying.

“All right, on to the next one.”

“No, please wait a moment.”

“What’s wrong?”

“Gorouzaburou is still alive.”

Shigeto looked down at the fallen Sage. Though he had collapsed, his fingers were still twitching.

“What’s going on? Isn’t the sword supposed to be omnipotent?”

“It executed your order to kill him perfectly.”

“Wait, does that mean he came back to life after dying?”

“There seems to be an object from another world buried inside him. That is what revived him. It is unrelated to the Battlesong system, so your previous order failed to neutralize it.”

“Then I’ll just take it out of him. Omega Blade, remove the object inside Gorouzaburou’s body.” As he spoke, the Sage’s back exploded, a small translucent stone bursting out of it. The stone floated up and into Shigeto’s palm.

“So this is what you were talking about? What is it?”

“As the source of the Sages’ power, they call it a Philosopher’s Stone.”
