Life Simulation: Propose Marriage To Kushina Uzumaki at the Beginning

"From this moment on, things began to slip out of Hagoromo's control, for he had no idea who was actually opposing him behind the scenes."

"At this time, he could never have imagined that his mother, Kaguya, would create another being at the moment when he and his brother had sealed her. That being was Black Zetsu."

"Black Zetsu not only concealed his identity perfectly, but since he hadn't inherited Kaguya's other powers, even the Sage of Six Paths couldn't detect his presence. With these remarkable concealment abilities, it began carefully plotting to achieve its goals."

"And Black Zetsu's goal, as everyone probably knows, was to resurrect Kaguya. He had always been working toward this single purpose."

"I can't help but admire Black Zetsu's patience. He plotted in the ninja world for nearly a thousand years. Ask yourselves — could you scheme for a thousand years?"

Yusuke said this, his face showing a trace of admiration.

But that was as far as it went. After all, he was now destined to be Black Zetsu's enemy — his adversary. He had to kill it.

"This ability was truly extraordinary. None of us could have orchestrated such a grand scheme over a thousand years. What we never expected was that Black Zetsu was behind everything — this revelation shocked us all. But I'm curious about something: since it had been plotting for so long, did the Sage of Six Paths and his two sons, Indra and Asura, really not notice anything at all?"

Facing Hashirama's doubts, Yusuke's face showed a faint smile.

Then he continued, "That's an excellent question. I'll tell you plainly: Hagoromo never discovered Black Zetsu's existence. But between Indra and Asura, one of them knew about it. Based on the current situation, you can probably guess who it was."

"That's right, it was Indra. Having inherited his father's Yin nature, along with chakra and various powerful kekkei genkai, he drew Black Zetsu's attention. But the Sage of Six Paths remained unaware of this as he set up a succession challenge for Indra and Asura. In the end, this succession issue would prove to be his downfall."

After saying this, Yusuke took a deep breath. He closed his eyes and slowly organized his thoughts.

Next, he looked at everyone present and began to explain the matter.

"All of the Sage of Six Paths' careful planning and schemes were ultimately undone by his successor selection process. Under his leadership, he had established a vast village where relations between different tribes were harmonious."

"However, with the emergence of Indra and Asura, two distinct factions formed. One faction rallied behind Indra, drawn to his incredible power. As the inventor of hand signs and the one who taught them to harness chakra, Indra commanded the loyalty of nearly seventy percent of the village."

"These followers believed wholeheartedly in his power, convinced he would grant them great strength. This faith wasn't misplaced — Indra did teach them many powerful ninja techniques, being the originator of Ninjutsu."

"But something went awry in the Sage of Six Paths' judgment." Yusuke said calmly, "Upon realizing the extent of his son's immense power, Hagoromo began contemplating the formal selection of his successor. Though he recognized Indra's power and confidence, he found his elder son lacking the qualities he saw in Asura. Specifically, Asura possessed the ability to connect with people.

"Without this essential quality, Hagoromo hesitated to entrust the village to Indra, regardless of his power. In response, he devised a test for the two brothers. As he prepared this challenge, Indra sensed something was amiss."

"He questioned the complexity of the selection process. Why hadn't his father simply chosen the most capable protector for the village? Instead, he had created an elaborate test to determine the succession between him and Asura."

"This decision would prove to be Hagoromo's grave mistake — using a test to determine whether Indra or Asura would inherit leadership of the village."

"The test involved two similar villages in different locations. Both territories were plagued by remnants of the Ten-Tails' roots, which had contaminated their water sources for years and caused widespread disease."

"Hagoromo presented this challenge to Indra and Asura: if they could resolve the problem of these roots, he would judge their methods and determine the true heir to the ninja village."
