An Earth youth carries an immortal world's greatest treasure and travels to another world, thus embarking on an unconventional path of artifact cultivation.
Want to become powerful? Warriors need to sit in meditation and train, while mages must meditate and study. However, Robin just needs to keep eating, using his body as a cauldron to refine everything, eventually turning different parts of his body into unique magical artifacts, cultivating an invincible treasure-filled body.
An awesome life doesn't require cultivation!
