Weeks ticked by.
[Immortal Sakura] had been simple for Ryu due to the initial foundation laid by Eska's guidance in combination with his Heavenly Pupils. The questions Ryu asked back then seemed to going around in circles, but they were very pointed and sometimes touched the core of the technique.
However, Flora was obviously not here to guide Ryu. Even if she was, Ryu wouldn't trust those Zu Ancestors again. Still, in just a month and half, Ryu broke into the third Divine Pestle Stage.
For [Immortal Sakura], Ryu held off on entering its third stage because the consumption was too great. But, for [Divine Chaotic Annihilation], the trade off for consumption based on return value was too good to give up. If the first stage was granted a value of one, the third stage was over ten thousand.
