No Way
Ryu's Realm Heart had gone through a lot of changes in its life, and everything seemed to deviate it further and further from what it was meant and designed to be.
When he first got it, it was used as a replacement for his dantian, and that much was fine enough. However, after he reaffirmed his connection with his Chaotic Silk Meridians, it was forced to undergo a different sort of change, being influenced now by both its own path and that of Ryu's.
As though that wasn't enough, Ryu then began to use it to store his true Spiritual Foundation, and that inevitably caused another series of changes.
After all, it had to be remembered that the Spiritual Foundation was the manifestation of one's Dao Heart. The form itself was less important than the soul it represented. That meant, in essence, Ryu's soul and the soul of the Realm Heart were suddenly occupying the same space, causing it to undergo even more changes.
