See Through
The Favor Alchemy Sky God was silent as she paid some attention to Ryu, but in reality her heart was beating quite fast.
In truth, the [Absolute Domain] technique wasn't as simple as it seemed. Though it was funny to say this considering just how complex it was, what she meant by this was that it wasn't just a movement technique like Ryu thought. Rather than just a movement technique, it was more accurate to say that this "movement" technique was the very foundation of her race's strength. Every one of their techniques, talents and Daos were built off of it as a foundation.
Adjusting such a foundational technique wasn't nearly as easy as Ryu was making it sound. The more things a technique relied upon, the more set in its ways it was. Just like how Ryu struggled so greatly with dual wielding spears, glaives and halberds because there was too much Fate weighing it down, [Absolute Domain] was similar.
