In the thousand years that Ravier had been busy, Shiba and Eini didn't slack on their training.
Eini had finally become a Law God in the Fire Law. Since she didn't need a tribulation, it was a smooth breakthrough, and she hadn't even had the chance to tell her father yet. She had also improved a lot on the Life Law, but it was a difficult Law, so she hadn't become a Law God yet.
Shiba didn't lack behind because he was on the verge of becoming a Law God with the Wind Law, but for fear of the tribulation, he put his attention into his other Laws at Law Master level first.
After his last tribulation, he felt that it would be better if he could ask his father-in-law for some tips just in case. After all, it would be stupid to have an origin God available to ask questions and not ask anything.
Still, Shiba didn't want to disturb him while he was busy, so he had been waiting the whole time.
