Sam and Sai arrived at the tempest valley in a few hours. Sai initially felt that he has to walk slower because of Sam, but it turned out to be another way around. Although Sam wouldn't be able to beat his top speed, he is as fast as Pre-transcendent on the Harbinger.
He can vaguely see that it is not his top speed.
After reaching the tempest valley, Sam stored his harbinger and stood there with Sai.
"It is better to let the beast out," Sai said and Sam let the Raiju out.
Sai was a bit surprised when he saw the beast. There is some change which he can put his finger on. But he is sure that there is something that changed with this beast.
He took out the white fur just in case and all three of them started walking inside.
When they reached the vicinities of the central area with the most lightning, Sai said.
"Sam is here."
