Hokage: I Confronted the Five Kage Before the System Arrived

Chapter 140: Truth-Seeking Ball: Yin-Yang and Five Elements

Hagoromo Gengetsu extended his right hand, palm up. Using Yin-Yang Release, a small black sphere, about the size of a ping-pong ball, appeared in his hand. The first step, creating a form with Yin-Yang Release, was complete.

The second step involved adding high-density chakra from seven attributes: Yin, Yang, Fire, Earth, Wind, Water, and Lightning. Hagoromo Gengetsu concentrated, channeling these chakras into the black sphere. This task was challenging and required an in-depth understanding of the nature transformation of these elements to prevent them from clashing and causing a violent reaction.

Despite his expertise, even Hagoromo Gengetsu had to focus intensely, not allowing a single distraction. After a few seconds of stability, the black sphere started to destabilize and exploded with a deafening roar. The explosion's force was comparable to an S-rank jutsu, but Hagoromo Gengetsu was prepared. He absorbed the energy with Yin Release, leaving the lab unscathed except for some scattered papers.

"It still doesn't work?" Hagoromo Gengetsu sighed. His experiment was an attempt to create the "Truth-Seeking Ball," a unique ninjutsu known to Six Paths-level beings, who typically have several floating behind them. These balls, made of all elements, could change into any form, providing immense power. Unlike bloodline limits or selections, Truth-Seeking Balls are classified as "ninjutsu."

Although these beings naturally acquire them upon reaching Six Paths-level, individuals like Hagoromo Gengetsu, with a deep understanding of the seven chakra natures, could potentially create them manually. His attempt failed, but he remained optimistic due to his advanced knowledge.

"The fusion of the seven chakra natures still feels rough, and my understanding of Yin and Yang Release is lacking. But these are fixable issues," he thought. With more time and research, Hagoromo Gengetsu was confident he could achieve mastery over the Truth-Seeking Balls, elevating his power significantly.

He recalled a similar concept in the "Fury of Heaven Forbidden Technique," which balanced chakra and natural energy in a similar structure, considering it as a potential model. He also noted the benefits of studying the Sharingan's abilities further and contemplated researching Hashirama cells.

After a significant journey through the Land of Fire, which brought him new insights into senjutsu, Hagoromo Gengetsu recognized the necessity of time. He had learned from the lesson of the Valley of the Fallen God that rushing ambitions or vengeance was not his priority; he simply needed time.

At 25, still in the prime of his life and ninja career, Hagoromo Gengetsu knew that while most ninjas reach a plateau, his continuous progress meant that given enough time, he could achieve his goals without distraction.

He had temporarily diverted the attention of the Five Great Nations from the Land of Keys, assigning the running of Lockfront Village and the Hagoromo Clan to Moteni and others, while he focused on his training and experiments.

However, his tranquility and progress were short-lived. While attempting another experiment with the Truth-Seeking Ball, he noticed a sudden disturbance emanating from the Mangekyō Sharingan soaking in a container nearby. Realizing there was no external manipulation involved, Hagoromo Gengetsu speculated that it could be linked to Uchiha Shisui's other Mangekyō Sharingan.

The doppelgänger, whose right eye now housed the Mangekyō Sharingan, noticed the approaching presence connected to the Sharingan's power, confirming the origin of the disturbance. "So, it's the other Mangekyō Sharingan of Uchiha Shisui?" Hagoromo Gengetsu thought, amused by the unexpected pursuit.

Deciding to meet this approaching presence, Hagoromo Gengetsu ordered the doppelgänger to prepare. The clone, equipped with the Mangekyō Sharingan, vanished from the lab, ready to face the oncoming encounter.
