Kagami appeared in a desert in an uninhabited region of the world. This was the entrance to the Pure Land. It was hidden in another dimension, and unless one had a profound knowledge of space, its existence could not be sensed. But Kagami, with his Taixu Yujie God, could. He had hurried here because he had sensed a change in the Pure Land, a change that made him uneasy. He felt that if he had come a step later, he might have missed something important.
He took out Yamato, the artifact from his Vergil template, and poured his surging demonic power into it. The patterns on the blade flickered with a strange light. He swung it forward, and a huge black crack appeared in the space before him, connecting reality to the Pure Land, filled with an endless cold and the stench of death. Unafraid, Kagami stepped through. The crack slowly healed behind him, and the desert returned to its silent calm.
In the center of the Pure Land, the Sage of Six Paths floated in the air. He suddenly opened his eyes, which were filled with excitement and madness. Under Kagami's instigation, wars raged across the ninja world, and countless souls poured into the Pure Land, providing him with a constant supply of soul power. With Kagami's unwitting help, the Sage had completely refined the authority of the ninja world ahead of schedule. At this moment, he was an immortal god, holding all power in the world.
"I have finally done it!" he laughed crazily. "Now I am an immortal god! I control all the power in the ninja world. No one can threaten me anymore!" He had waited for this day for too long. His eyes turned icy cold. "Kagami, I really should thank you! If it weren't for you, I wouldn't have succeeded so quickly. But even so, I will never let you go! I will tear you to pieces!"
At that moment, he felt a strange presence approaching the Pure Land. He frowned. "Who dares to trespass into the pure land created by this immortal?" The Pure Land was his creation; no one but him could sense it or open a passage to it. But now, someone had entered. When he realized it was Kagami, a ferocious murderous intent appeared on his face. "Kagami, you actually dared to come to my door! Today, I will tear you to pieces to vent my hatred!" He vanished, rushing toward Kagami.
Kagami had arrived in a gray, empty space. He released his perception and immediately felt the Sage approaching. "Sage of Six Paths," he sneered, "you've arrived just in time. Today is the day I take your life."
The Sage appeared before him, surrounded by a vast amount of chakra, his eyes filled with a terrifying murderous intent. "Kagami, you've ruined my plan. I'm going to torture you to death!"
Kagami couldn't help but laugh. "Hagoromo Ōtsutsuki, you rebellious son! Is this how you talk to your father?" Since Kaguya was now his woman, and Hagoromo was her son, it wasn't a stretch to call himself the Sage's father. "Today, let your father teach you a lesson about filial piety!" His aura suddenly burst forth, colliding with the Sage's. The surrounding space distorted.
"Kagami, since you want to die, then I will grant your wish!" the Sage roared, enraged. He raised his right hand, and five terrifying ninjutsu of different attributes shot toward Kagami, each powerful enough to destroy a mountain.
But Kagami showed no fear. He took a step forward, his Mangekyo Sharingan opening. A huge black Susanoo appeared behind him, raising its giant sword and slashing at the five ninjutsu. With five earth-shaking booms, the attacks were cut in half. Kagami didn't stop, controlling his Susanoo to continue its charge toward the Sage of Six Paths.
