Healing Master

The end wasn't considered the end for someone like the Sun Celestial. Although his Celestial body had been destroyed by David, his true body was within a secret realm where he was absorbing cosmic energies to improve his strength and recuperate from his hidden injuries.

And so it began.

"Cough!!! Ughhhh!!!"

Blood escaped in the form of a mist, merging into the surrounding energy and disappearing into the air.  The principle- energy cannot be destroyed and can only be converted from one form to another seem very true at the moment. The Sun Celestial Celestial body although made in the form of a true body, is the accumulation of various types of energies, matter, precious resources and time to create his own Celestial body.

Meanwhile the Celestial body isn't the strongest form of a Celestial, it could be the said to be a perfect clone of the true body, and might even be stronger than the true body of the Celestial in some aspect.
