"Smack

The green aura surrounded my entire body. The pain in the abdomen gradually subsided.

... It must have been Asia who sent me the recovery aura. Just at the right moment. Just now, I really was about to lose consciousness.

However, the wound was still open. And smoking a bit. No way, it looks as if it is about to expand again! Was it because the healing provided from a distance was not strong enough? Asia's distance healing was very effective but still inferior compared to her direct touch... Still, long range healing was already very powerful, but the holy spear's damage seems to have exceeded it.

I took out the Phoenix Tears from my shirt pocket, and scattered them over the wound on my abdomen... The wound finally closed."

So it was Asia's distance healing that couldn't heal True Lonignus' damage.
