Lin Yuan entered his inner world.

"Thunder Heart."

Lin Yuan used twelve thousand cubic Cosmic Crystals, trading for the eighth-level supreme cosmic treasure, slowly merging it into his inner world.

A cosmic treasure like the Thunder Heart clearly exceeded a cosmic treasure like the 'Primordial Fire.'

This could be seen from its value.

"My current strength should be considered first in the sequence right below the invincible of the Eighth Layer....." Lin Yuan thought to himself.
