This was the Soul Society. Setting aside just how strong its spatial defenses were, the spatial barrier of the Soul Society alone was far thicker than that of Karakura Town in the Human World.
Other than the normal passage that had been opened to Karakura Town in the Human World, it was nearly impossible to carve out another passage through the void here!!!
Uchiha Hikaru looked at the purple-black rift in the void, which was only about the height of a person, and thought, This must be the backup Aizen Sosuke left behind.
Drawing his gaze back, Uchiha Hikaru stood three or four steps behind Aizen Sosuke. He tightened his grip on the Nether Flame Blade and fixed his eyes on Aizen Sosuke's back!!
Then he suddenly thrust forward!!
"Hmm???" Aizen Sosuke suddenly felt a chill at the spot over his heart on his back. Instinctively, he shifted slightly to the right.
"Ugh~~~" A transparent Ryujin Jakka instantly pierced through Aizen Sosuke's chest. Blood dripped from the invisible blade tip, outlining the shape of the blade.
Aizen Sosuke stared in disbelief at the Zanpakuto protruding through his chest. He could only feel the life force within him constantly draining away as his body grew increasingly exhausted...
His hand left Sokyoku, and the light surrounding it instantly dissipated. The blade aura around Sokyoku also immediately stopped spilling outward.
Uchiha Hikaru shifted into physical form, and his figure gradually appeared.
Aizen Sosuke turned around with difficulty and looked at Uchiha Hikaru, the man he had drunk and chatted merrily with only months ago...
"This bastard!!!"
"He actually deceived me..."
Uchiha Hikaru's lips curled into a faint smile. "Aizen, if you had dodged that strike just now, you would have been fine."
"But since you walked right into the line of fire yourself."
