Swallowing the Stars, Starting with the Cosmic Genius Battle

Arriving in the world of Swallowed Star, I start as a mere apprentice-level mentalist. Fortunately, the Cosmic Genius Battle is about to begin. Knowing the plot's direction, I bet my entire fortune on the winner, gaining a large amount of cosmic coins. I invest heavily in cultivation, achieving immortality and eternity. P.S.: A small character's cultivation journey in the world of Swallowed Star, comprehending the mysteries of the universe.
