Back to an earlier time.
Uchiha Onibi raced through the dense forest with his unconscious younger brother on his back.
His Body Flicker Technique was incredibly fast, carrying him dozens of meters with each flicker.
However, although he had temporarily stopped the bleeding from the wound piercing Ryota Uchiha's abdomen with basic Medical Ninjutsu, his brother's internal organs were severely damaged. He had lost too much blood, and his condition was critical.
Uchiha Onibi felt that even Lady Tsunade from the village might not be able to save his brother if she were here.
After using the Body Flicker Technique again to appear on the branch of a large tree, Uchiha Onibi stopped.
He gently lowered Ryota Uchiha and propped him against the trunk.
Looking at his brother's pale face, a trace of fierceness flashed across Uchiha Onibi's face, and his newly awakened Mangekyō Sharingan involuntarily appeared again.
"Ryōta, hang on!"
Uchiha Onibi murmured, the Mangekyō pattern in his right eye suddenly spinning faster!
A power different from ordinary chakra, deeper and colder, poured from his right eye.
He stared intently at his brother's badly wounded body and silently commanded:
Turn back!
An invisible, indescribable power of law enveloped Ryota Uchiha.
The next moment, a miracle occurred!
The hideous wounds on Ryota Uchiha's body began reversing at a speed visible to the naked eye!
The blood that had flowed out retreated into his body as though alive. His torn clothes rewove themselves as if time were running backward. The wound piercing his abdomen rapidly healed without leaving even a scar. The cut on his face, deep enough to expose bone, vanished completely, leaving smooth skin. His broken arm rejoined itself, as though he had never been injured!
Even his depleted stamina and chakra returned to their states before his injuries!
