Hyuga Shinichi's Byakugan snapped open, and a wave of pressure flooded the courtyard, nearly knocking the two spectators off their feet.
The pressure vanished as quickly as it had appeared, leaving Hyuga Shinichi kneeling on the ground, gasping for air.
Uzumaki Mito, unfazed by the pressure, stepped forward to help Hyuga Shinichi up.
"How are you, Shinichi?"
Uzumaki Mito looked at him, her face full of concern.
Hyuga Shinichi managed a weak smile and shook his head, signaling that he was fine, just drained of energy.
At this moment, Jiraiya regained his composure and exclaimed in wonder.
"What was that just now? Does the Byakugan really have that kind of power?"
Whoosh! Whoosh!
Two figures appeared beside Jiraiya: Tsunade and Dan Katō. Both had sensed something while they were sleeping and had rushed to the courtyard immediately.
"What's going on, Jiraiya?"
"Shinichi... Shinichi just used a Byakugan ability we've never seen before."
Jiraiya said with a grave expression.
Tsunade looked at the pale, exhausted Hyuga Shinichi, her heart filled with doubt and worry. Seeing this, Dan Katō analyzed the situation.
"Is it because Shinichi used that ability that he's in such a bad state now?"
Jiraiya nodded, and Tsunade decided to check Hyuga Shinichi's physical condition first.
She stepped forward to help Uzumaki Mito guide Hyuga Shinichi to a place to rest, then used medical ninjutsu to diagnose him. During this time, Nawaki also arrived in the courtyard; upon hearing the situation from Jiraiya, he wore a worried expression.
A moment later, the frown that had been etched on Tsunade's face finally relaxed.
"Shinichi's chakra was completely depleted all at once. He just needs to rest in this state. But how did this situation even come about?"
Hyuga Shinichi had already caught his breath while sitting down, and by the time Tsunade finished her diagnosis, he was feeling much better and could communicate normally.
"Big sister, it was a technique I activated with my Byakugan. It was my first time using it actively, and I didn't control it well, so it drained all the chakra in my body. If it weren't for the chakra supply in my Yin Seal, I probably would have fainted just now."
Seeing that Hyuga Shinichi was fine and understanding the sequence of events, everyone relaxed.
Nawaki didn't fully grasp what had happened, but he knew Hyuga Shinichi had grown stronger again.
"Damn it, Shinichi, you've gotten stronger again, but I won't give up! Once you've rested, we're still going to have that fight we promised. Let me see the gap between us now!"
"Heh, don't go crying and making excuses when the time comes. Same old rules: the winner gets a bowl of ramen."
"How are you, Shinichi?"
Hyuga Shinichi knew very well that Mito was not asking about his physical condition this time, but about the Byakugan's pressure.
"Grandmother, it feels like something is still missing. This time, there was only the sensation of a chakra burst; it's very different from the effect I achieved the first time."
"Could it be that there is less spiritual energy in the chakra? To make others feel a sense of oppression, it should be a spiritual attack."
Uzumaki Mito recalled the feeling brought on by the Byakugan's pressure earlier.
"I only felt pressure and a bit of impact just now. It seems ordinary chakra can only cause physical impact, making the body feel pressure. As for the spiritual aspect, we were only surprised because we were caught off guard; we didn't feel anything else."
"Then, Grandmother, what should I do next?"
"I'm not sure, but I have a guess. It might be similar to the awakening of the Sharingan. I once read through Tobirama's old notes on his research into the Uchiha; the awakening of the Sharingan requires emotional stimulation."
"Special chakra surges in the brain and eventually acts on the optic nerve. The Byakugan's pressure might follow the same principle."
"That sounds like it's getting even more complicated, Grandmother."
"Mm, take your time and ponder it. You haven't even mastered the sealing techniques I taught you yet, so there's no rush for this."
Finally, Hyuga Shinichi returned to his room to rest, supported by Jiraiya and Nawaki.
Hearing that Nawaki was going out for a stroll, he gave him Namikaze Minato's address and asked him to let Minato know that he was resting and would come to see him in the afternoon.
"Big Brother Jiraiya, this Minato is the person I want to recommend to you. You can come over to see him this afternoon."
"Oh, really? It seems you care quite a lot about him."
"Of course. What kind of older brother doesn't care about his younger brother?"
"So you've already accepted him as a younger brother? Well, I'm certainly looking forward to it. Get some rest; we're leaving."
The sound of the door closing followed, leaving Hyuga Shinichi alone in the room.
Lying on the bed, his consciousness gradually blurred as he drifted into a dream.
In his dream, Hyuga Shinichi arrived in a space with a pure white background.
"Where is this? My mental world?"
Suddenly, a voice like an ancient chime boomed in Hyuga Shinichi's ears. The sound carried the weight of history and the vicissitudes of time, as if it could pierce through a person's soul.
"Approaching perfect... purity... Byakugan. Is it Otsutsuki... No, just a Byakugan... has it atavized?"
Hearing this voice, Hyuga Shinichi tried hard to see the surrounding environment, but he could never manage to do so.
Suddenly, a blinding white light shone from somewhere in the space, and he instinctively covered his eyes with his hand.
When Hyuga Shinichi opened his eyes again, he found himself in an unfamiliar place, standing before an elderly man with a wrinkled face dressed in white robes.
Two short white horns grew from the sides of his forehead, and he wore his white hair long; his eyes were unmistakably a pair of Byakugan, and his entire being exuded a mysterious, ancient aura.
As a reincarnator, how could Hyuga Shinichi not know who this was? It was Hamura Otsutsuki, the brother of the Sage of Six Paths, and the ancestor of both the Otsutsuki Clan on the moon and their descendants, the Hyuga Clan.
"Who are you?"
Even though Hyuga Shinichi knew who the other party was, he still feigned vigilance; after all, he had no idea what his current situation was.
The old man smiled slightly.
"My name is Hamura Otsutsuki, and I suppose you could call me your ancestor."
"Then why have you appeared in my dream?"
The old man spoke slowly.
"Whenever I sense the power of the Byakugan awakening, I manifest in the form of chakra."
Upon hearing this, Hyuga Shinichi could not help but feel puzzled.
In the original story, after the Sage of Six Paths died, his chakra continued to drift through the world, silently guarding the ninja world.
But his brother had supposedly passed away peacefully after leaving his final testament to the Otsutsuki Clan on the moon; he had never heard of him pulling a stunt like this.
Hamura Otsutsuki paid no mind to Hyuga Shinichi's confused expression and continued.
"Child, the purity of your Byakugan is very high, one could even say it is near perfect. Aside from my mother, I have never seen a Byakugan of this purity, yet you have not fully mastered it."
Hyuga Shinichi's expression turned serious and respectful; he bowed slightly and asked in a sincere tone.
"May I ask, Ancestor, what must I do to fully master the Byakugan?"
Hamura Otsutsuki did not speak, but instead extended a finger and tapped the air, sending a ball of light flying toward Hyuga Shinichi, which then merged into his body.
Hyuga Shinichi suddenly felt a warm current flow into his body like a clear spring, bringing a sense of comfort and pleasure wherever it passed.
This mysterious power rapidly spread to every corner of his body, as if injecting new vitality and life into every single cell.
As this power continued to gather and fuse, Hyuga Shinichi was astonished to discover that his Byakugan had undergone a miraculous change!
