Milky Way Main Star.

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.

Whoosh.

Threads of purple lightning began to fill the vast inner world, stretching over two million miles.

The purple lightning was filled with a sense of destruction, yet it also surged with vibrant life, making the entire inner world suddenly more realistic.

"As expected of the Thunder Heart."

Lin Yuan felt the changes in his inner world.

A satisfied expression appeared on his face.

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.
