At this moment, on a plain, Uchiha Hikari's Mangekyō Sharingan gleamed with an eerie light. Faint Dragon Vein Power slowly rose like mist and, under the control of Hikari's Yachihoko ocular technique, gradually flowed into a sealing scroll, forming a black character for "dragon."
"Phew..."
Hikari covered her eyes and let out a long breath. Naruto hurried over to support her.
Leaning against Naruto's chest, Hikari revealed a faint smile. "Naruto, I finally completed one. Give me another two days, and I can make another Dragon Vein Scroll."
"You've worked hard, Hikari. Get some rest. Using your ocular technique nonstop for two days to collect it has put a huge strain on your body. You can't force yourself like this."
Naruto scooped Hikari up in a princess carry. After putting away the Dragon Vein Scroll, he carefully carried her back to camp.
"Mm!"
Hikari softly murmured in response and fell asleep from exhaustion.
Collecting the Dragon Vein had been even more difficult than expected. Since it was energy belonging to the planet itself, Hikari could not simply implant an inscription into the Dragon Vein Power and let it burst from the ground like a volcanic eruption. That could even destroy this world.
So, Hikari could only allow the Dragon Vein Power to seep out from the surface as mist, then gather it and seal it inside scrolls.
This method severely tested Hikari's endurance, chakra control, and mastery of her Mangekyō Sharingan ocular technique. Collecting Dragon Vein Power had indirectly become training for her.
Naruto made a rough estimate of Hanabi Hyuga and Uchiha Hikari's current chakra control. Hanabi was now tens of thousands of times better than Sakura at it, while Hikari was hundreds of times better.
