Watanabe Ichiro had left as soon as Kagami Uchiha arrived.
He passed through the wall and plunged straight into Tobirama Senju's Laboratory.
When he had activated his Rinnegan ability earlier, the system had actually recognized two Artificial Humans in the Laboratory as living beings. What did that mean?
