The spinning black hurricanes rapidly replenished the slain Foul Mutation Knights. Once their numbers had returned to twenty thousand, the four hurricanes ceased their rampage, transforming into four black rivers that flew back into the Death Knight's sword.
"That sword is a fine thing..." Ye Luo smacked his lips. If the black rivers were made up of countless souls, then that sword was the vessel that contained them! Souls were good things. Soul energy was a high-grade form of energy, unlike ordinary power sources.

Those two divine swords had been the weapons of the previous Heavenly Demon Emperor. Back then, the Heavenly Demon Emperor had entered the Immortal-Slaying Sword Formation alone, a formation set by one hundred and one Immortal Lords. Not only had he broken free of the formation, but he had also slaughtered thirty-one Immortal Lords!
