Senya and Hikari used the Dragon Vein's power from this era to teleport directly back to Senya's original timeline.
He did not absorb this Dragon Vein or anything like that. After all, this timeline itself was a branch of the World Tree in Senya's world.
Senya did not dare imagine what would happen to the timeline if he absorbed the Dragon Vein here.
Playing with time was dangerous to begin with. He had the nerve to be a little reckless in other timelines, but using himself as a guinea pig was another matter. There was no need for that.
Besides, the Dragon Vein's power had already completely fused into Senya's body. As long as he wished, he could create new Dragon Vein Chakra at any time.
Though rather than calling it Dragon Vein Chakra, Senya preferred to call it a Sage Mode best suited to humans.
At the same time, Senya could sense a brand-new power gestating within his eye sockets.
After all, the soul power left behind after Asura and Indra's consciousnesses had been extracted was all within him. He also possessed Uchiha blood and Wood Release cells copied from Obito.
Still, Senya could clearly feel that the process was rather slow. At this rate, it would probably take at least thirty or forty years for his Rinnegan to awaken.
But that was not much of a problem. Once he returned, he could find Orochimaru and get some Hashirama Cells.
Senya and Hikari reappeared inside the abandoned tower.
The familiar sight before him could not help but remind Senya of the first time he had absorbed the Dragon Vein.
"I didn't expect time to pass so quickly. I've already been away from here for more than half a year."
From Senya's perspective, only half a year had truly passed.
