Milky Way Main Star.

Lin Yuan arrived at his Inner World.

Lin Yuan slowly merged the Eight-Star Supreme Cosmic Rare Treasure he had traded for 12,000 Cubic Universe Crystals into his Inner World.

A Cosmic Rare Treasure like the Thunder Heart was clearly superior to others like the 'Primordial Fire'.

This could be seen from their values.
