Ryu's gaze flickered. This changed a lot of things.
If he could enter the Crystalline Jade while it was within his Inner World, it would be able to save his life at a crucial moment.
The Inner World of a Heavenly Pupil wielder was cut off from normal space. It would take an absolute expert with a top tier Spatial Inheritance or someone above the True Sky God level to pinpoint its location without the protection of Ryu's body.
If Ryu performed this, it would be like he vanished into thin air. The residual traces would be something, again, only someone like Yaana or someone above the True Sky God Realm could trace. It was definitely a nice card to have so long as Ryu had a small buffer of time to execute it.
