Chapter 303: Explosion in Strength, Physical Body Heavenly Immortal Realm! [8k]

[In the one hundred and fiftieth year, you thoroughly repaired the Flowing Cloud Golden Light Boat...]

[With years of artifact refining, your artifact refining skills had improved, and you were now capable of attempting to refine top-grade Immortal Treasures...]

[However, the materials needed for top-grade Immortal Treasures were exceedingly rare!]

[To refine a top-grade Immortal Treasure, the material costs were nearly a billion high-grade Spirit Stones, over ten times the cost of refining a high-grade Immortal Treasure...]

"Nearly a billion high-grade Spirit Stones... that's tens of millions of top-grade Spirit Stones!"

"Only a True Immortal could possess such wealth, right?"

Top-grade Immortal Treasures were originally meant for True Immortals, to be able to unleash their maximum power.
