Only Shiba knew how much time he trained because Yale had left him too many times in a separate dimension with a modified time flow without even caring about how much it was.
Although the training was harsh, Shiba managed to obtain the Minor Dimensional Divinity thanks to it.
"Master, I finally did it."
That was the first time he managed to flee from one of the dimensions Yale used to isolate him.
The strength to flee form that dimension was just that of the Minor Dimensional Divinity, so it had been the best training to obtain it. However, even a Great God would go crazy staying in those dimensions for too long, so Yale took Shiba out from time to time.
"Good job. Now we can proceed to the next level. Are you ready?"
Yale wanted to continue with the training, but he didn't plan to force Shiba if he didn't want to do it.
"Of course. I am always ready."
