The Shinobi World, a forbidden area in the mountains behind the Hyuga Clan.
"I think..." Hyuga Kenji said, his head still spinning. He felt like he was about to throw up. "Your Space-Time Ninjutsu needs some adjustments."
Long-distance teleportation was like riding in a boat. The swaying was so disorienting that some people experienced nausea and vomiting.
Poor Hyuga Kenji. He probably wouldn't learn even the simplest Space-Time Ninjutsu in ten lifetimes.
"Thanks for your effort." Hyuga Tenjin took over, offering Kyosuke his heartfelt thanks.
Without the Uchiha boy, he would never have guessed that the key to awakening the Tenseigan lay on the moon.
Now that they had the body of a member of the Otsutsuki Main Family, all it would take was a period of experimentation for the Hyuga Clan to gain a fighter who surpassed Clan Leader Level.
His own strength had plateaued, and there wasn't much room left for him to grow. Such a precious bloodline shouldn't be wasted on him.
Besides, Hyuga Tenjin had agreed to the Uchiha Clan's request for an alliance, and didn't have time to slowly cultivate his eyes.
But his son was different. He was still young and had great potential.
As long as the transplant succeeded, he would surely gain that legendary, ultimate power.
At the thought, he could no longer hold back his excitement. "Give me a few days to make arrangements here, then I'll set out with you right away."
"Please, take your time, Clan Head Tenjin." Kyosuke tactfully took his leave.
He knew Hyuga Tenjin would begin researching at once. Unfortunately, the Otsutsuki Clan's genes weren't so easy to acquire.
In the original story, Orochimaru, Danzo, and other scientists in the Shinobi World spent decades researching Hashirama Cells.
And what did they have to show for it?
